Image 5Two pieces of string under a light microscope String is a long flexible structure made from fibers twisted together into a single strand, or from multiple such strands which are in turn twisted together. String is used to tie, bind, or hang other objects. It is also used as a material to make things, such as textiles, and in arts and crafts. String is a simple tool, and its use by humans is known to have been developed tens of thousands of years ago. In Mesoamerica, for example, string was invented some 20,000 to 30,000 years ago, and was made by twisting plant fibers together. String may also be a component in other tools, and in devices as diverse as weapons, musical instruments, and toys. (Full article...)
Image 6 Trichophyton rubrum Trichophyton is a genus of fungi, which includes the parasitic varieties that cause tinea, including athlete's foot, ringworm, jock itch, and similar infections of the nail, beard, skin and scalp. Trichophyton fungi are molds characterized by the development of both smooth-walled macro- and microconidia. Macroconidia are mostly borne laterally directly on the hyphae or on short pedicels, and are thin- or thick-walled, clavate to fusiform, and range from 4 to 8 by 8 to 50 μm in size. Macroconidia are few or absent in many species. Microconidia are spherical, pyriform to clavate or of irregular shape, and range from 2 to 3 by 2 to 4 μm in size. (Full article...)
Image 7A depiction of Idris visiting Heaven and Hell from an illuminated manuscript version of the Islamic text Stories of the Prophets (1577) The afterlife or life after death is a purported existence in which the essential part of an individual's stream of consciousness or identity continues to exist after the death of their physical body. The surviving essential aspect varies between belief systems; it may be some partial element, or the entire soul or spirit, which carries with it one's personal identity.
In some views, this continued existence takes place in a spiritual realm, while in others, the individual may be reborn into this world and begin the life cycle over again in a process referred to as reincarnation, likely with no memory of what they have done in the past. In this latter view, such rebirths and deaths may take place over and over again continuously until the individual gains entry to a spiritual realm or otherworld. Major views on the afterlife derive from religion, esotericism, and metaphysics.
Some belief systems, such as those in the Abrahamic tradition, hold that the dead go to a specific place (e.g., paradise or hell) after death, as determined by their god, based on their actions and beliefs during life. In contrast, in systems of reincarnation, such as those of the Indian religions, the nature of the continued existence is determined directly by the actions of the individual in the ended life.

Image 8Life extension is the concept of extending the human lifespan, either modestly through improvements in medicine or dramatically by increasing the maximum lifespan beyond its generally-settled biological limit of around 125 years. Several researchers in the area, along with "life extensionists", "immortalists", or "longevists" (those who wish to achieve longer lives themselves), postulate that future breakthroughs in tissue rejuvenation, stem cells, regenerative medicine, molecular repair, gene therapy, pharmaceuticals, and organ replacement (such as with artificial organs or xenotransplantations) will eventually enable humans to have indefinite lifespans through complete rejuvenation to a healthy youthful condition (agerasia). The ethical ramifications, if life extension becomes a possibility, are debated by bioethicists.
The sale of purported anti-aging products such as supplements and hormone replacement is a lucrative global industry. For example, the industry that promotes the use of hormones as a treatment for consumers to slow or reverse the aging process in the US market generated about $50 billion of revenue a year in 2009. The use of such hormone products has not been proven to be effective or safe. (Full article...)
One argument for the importance of this risk references how human beings dominate other species because the human brain possesses distinctive capabilities other animals lack. If AI were to surpass human intelligence and become superintelligent, it might become uncontrollable. Just as the fate of the mountain gorilla depends on human goodwill, the fate of humanity could depend on the actions of a future machine superintelligence.
The plausibility of existential catastrophe due to AI is widely debated. It hinges in part on whether AGI or superintelligence are achievable, the speed at which dangerous capabilities and behaviors emerge, and whether practical scenarios for AI takeovers exist. Concerns about superintelligence have been voiced by computer scientists and tech CEOs such as Geoffrey Hinton, Yoshua Bengio, Alan Turing, Elon Musk, and OpenAI CEO Sam Altman. In 2022, a survey of AI researchers with a 17% response rate found that the majority believed there is a 10 percent or greater chance that human inability to control AI will cause an existential catastrophe. In 2023, hundreds of AI experts and other notable figures signed a statement declaring, "Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war". Following increased concern over AI risks, government leaders such as United Kingdom prime ministerRishi Sunak and United Nations Secretary-GeneralAntónio Guterres called for an increased focus on global AI regulation.
Two sources of concern stem from the problems of AI control and alignment. Controlling a superintelligent machine or instilling it with human-compatible values may be difficult. Many researchers believe that a superintelligent machine would likely resist attempts to disable it or change its goals as that would prevent it from accomplishing its present goals. It would be extremely challenging to align a superintelligence with the full breadth of significant human values and constraints. In contrast, skeptics such as computer scientistYann LeCun argue that superintelligent machines will have no desire for self-preservation. (Full article...)
Image 10An EXCOMM meeting during the Cuban Missile Crisis, a crisis between the United States and Soviet Union over ballistic missiles in Cuba A crisis (pl.: crises; ADJ: critical) is any event or period that will lead to an unstable and dangerous situation affecting an individual, group, or all of society. Crises are negative changes in the human or environmental affairs, especially when they occur abruptly, with little or no warning. More loosely, a crisis is a testing time for an emergency.

Image 11Emerging technologies are technologies whose development, practical applications, or both are still largely unrealized. These technologies are generally new but also include old technologies finding new applications. Emerging technologies are often perceived as capable of changing the status quo.
Emerging technologies are characterized by radical novelty (in application even if not in origins), relatively fast growth, coherence, prominent impact, and uncertainty and ambiguity. In other words, an emerging technology can be defined as "a radically novel and relatively fast growing technology characterised by a certain degree of coherence persisting over time and with the potential to exert a considerable impact on the socio-economic domain(s) which is observed in terms of the composition of actors, institutions and patterns of interactions among those, along with the associated knowledge production processes. Its most prominent impact, however, lies in the future and so in the emergence phase is still somewhat uncertain and ambiguous."
New technological fields may result from the technological convergence of different systems evolving towards similar goals. Convergence brings previously separate technologies such as voice (and telephony features), data (and productivity applications) and video together so that they share resources and interact with each other, creating new efficiencies.

LCC has been criticized for lacking a sound theoretical basis; many of the classification decisions were driven by the practical needs of that library rather than epistemological considerations. Although it divides subjects into broad categories, it is essentially enumerative in nature. That is, it provides a guide to the books actually in one library's collections, not a classification of the world. (Full article...)

On the left is a Mars Exploration Rover (MER) test vehicle that is a working sibling to Spirit and Opportunity, which landed on Mars in 2004. On the right is a test rover for the Mars Science Laboratory, which landed Curiosity on Mars in 2012.
The goal of most robotics is to design machines that can help and assist humans. Many robots are built to do jobs that are hazardous to people, such as finding survivors in unstable ruins, and exploring space, mines and shipwrecks. Others replace people in jobs that are boring, repetitive, or unpleasant, such as cleaning, monitoring, transporting, and assembling. Today, robotics is a rapidly growing field, as technological advances continue; researching, designing, and building new robots serve various practical purposes. (Full article...)
Image 16A superintelligence is a hypothetical agent that possesses intelligence surpassing that of the brightest and most gifted human minds. "Superintelligence" may also refer to a property of problem-solving systems (e.g., superintelligent language translators or engineering assistants) whether or not these high-level intellectual competencies are embodied in agents that act in the world. A superintelligence may or may not be created by an intelligence explosion and associated with a technological singularity.
University of Oxford philosopher Nick Bostrom defines superintelligence as "any intellect that greatly exceeds the cognitive performance of humans in virtually all domains of interest". The program Fritz falls short of this conception of superintelligence—even though it is much better than humans at chess—because Fritz cannot outperform humans in other tasks.
Technological researchers disagree about how likely present-day human intelligence is to be surpassed. Some argue that advances in artificial intelligence (AI) will probably result in general reasoning systems that lack human cognitive limitations. Others believe that humans will evolve or directly modify their biology to achieve radically greater intelligence. Several future study scenarios combine elements from both of these possibilities, suggesting that humans are likely to interface with computers, or upload their minds to computers, in a way that enables substantial intelligence amplification.
Some researchers believe that superintelligence will likely follow shortly after the development of artificial general intelligence. The first generally intelligent machines are likely to immediately hold an enormous advantage in at least some forms of mental capability, including the capacity of perfect recall, a vastly superior knowledge base, and the ability to multitask in ways not possible to biological entities. This may allow them to — either as a single being or as a new species — become much more powerful than humans, and displace them. (Full article...)
Image 17Visualization of various methodological approaches to gaining insights from meta data areas
Information science is an academic field which is primarily concerned with analysis, collection, classification, manipulation, storage, retrieval, movement, dissemination, and protection of information. Practitioners within and outside the field study the application and the usage of knowledge in organizations in addition to the interaction between people, organizations, and any existing information systems with the aim of creating, replacing, improving, or understanding the information systems.
Visceral fat, also known as organ fat or intra-abdominal fat, is located inside the peritoneal cavity, packed in between internal organs and torso, as opposed to subcutaneous fat, which is found underneath the skin, and intramuscular fat, which is found interspersed in skeletal muscle. Visceral fat is composed of several adipose depots including mesenteric, epididymal white adipose tissue (EWAT), and perirenal fat. An excess of adipose visceral fat is known as central obesity, the "pot belly" or "beer belly" effect, in which the abdomen protrudes excessively. This body type is also known as "apple shaped", as opposed to "pear shaped" in which fat is deposited on the hips and buttocks.
Researchers first started to focus on abdominal obesity in the 1980s when they realized it had an important connection to cardiovascular disease, diabetes, and dyslipidemia. Abdominal obesity was more closely related with metabolic dysfunctions connected with cardiovascular disease than was general obesity. In the late 1980s and early 1990s insightful and powerful imaging techniques were discovered that would further help advance the understanding of the health risks associated with body fat accumulation. Techniques such as computed tomography and magnetic resonance imaging made it possible to categorize mass of adipose tissue located at the abdominal level into intra-abdominal fat and subcutaneous fat.

The same terminology can be used with the term "sentience" instead of "consciousness" when specifically designating phenomenal consciousness (the ability to feel qualia). Since sentience involves the ability to experience ethically positive or negative (i.e., valenced) mental states, it may justify welfare concerns and legal protection, as with animals.
Some scholars believe that consciousness is generated by the interoperation of various parts of the brain; these mechanisms are labeled the neural correlates of consciousness or NCC. Some further believe that constructing a system (e.g., a computer system) that can emulate this NCC interoperation would result in a system that is conscious. (Full article...)
Image 20A userscript manager, also known as a userscript engine, is a type of browser extension and augmented browsing technology that provides a user interface to run and organize userscripts. The main purpose of a userscript manager is to execute scripts on predetermined webpages as they are loaded, for example, running a userscript to modify only youtube.com pages. But, userscript managers do a lot more than execute scripts, and screen for the pages they are intended to run on. The most common operations performed by a userscript manager include installing, organizing, creating, copying, saving, deleting, and editing (including modifying webpage permissions of) userscripts.
Userscript managers use metadata that is embedded in a script's source code primarily to determine the websites it should execute on and the dependencies necessary for the script to run properly. Metadata can also include information that is useful to the user such as the script's name, author, description and version number.
Popular userscript managers include Tampermonkey, Greasemonkey, and Violentmonkey. The Gear browser for IOS has a userscript manager built in. (Full article...)
Image 22Artificial general intelligence (AGI) is a type of artificial intelligence (AI) that matches or surpasses human cognitive capabilities across a wide range of cognitive tasks. This contrasts with narrow AI, which is limited to specific tasks. Artificial superintelligence (ASI), on the other hand, refers to AGI that greatly exceeds human cognitive capabilities. AGI is considered one of the definitions of strong AI.
Creating AGI is a primary goal of AI research and of companies such as OpenAI and Meta. A 2020 survey identified 72 active AGI research and development projects across 37 countries.
The timeline for achieving AGI remains a subject of ongoing debate among researchers and experts. As of 2023, some argue that it may be possible in years or decades; others maintain it might take a century or longer; a minority believe it may never be achieved; and another minority claims that it is already here. Notable AI researcher Geoffrey Hinton has expressed concerns about the rapid progress towards AGI, suggesting it could be achieved sooner than many expect.
Image 23Etruscan: Diomedes and Polyxena, from the Etruscan amphora of the Pontic group, c. 540–530 BCE – From Vulci Ceramic art is art made from ceramic materials, including clay. It may take varied forms, including artistic pottery, including tableware, tiles, figurines and other sculpture. As one of the plastic arts, ceramic art is a visual art. While some ceramics are considered fine art, such as pottery or sculpture, most are considered to be decorative, industrial or applied art objects. Ceramic art can be created by one person or by a group, in a pottery or a ceramic factory with a group designing and manufacturing the artware.
In Britain and the United States, modern ceramics as an art took its inspiration in the early twentieth century from the Arts and Crafts movement, leading to the revival of pottery considered as a specifically modern craft. Such crafts emphasized traditional non-industrial production techniques, faithfulness to the material, the skills of the individual maker, attention to utility, and an absence of excessive decoration that was typical to the Victorian era.
The word "ceramics" comes from the Greek keramikos (κεραμεικός), meaning "pottery", which in turn comes from keramos (κέραμος) meaning "potter's clay". Most traditional ceramic products were made from clay (or clay mixed with other materials), shaped and subjected to heat, and tableware and decorative ceramics are generally still made this way. In modern ceramic engineering usage, ceramics is the art and science of making objects from inorganic, non-metallic materials by the action of heat. It excludes glass and mosaic made from glass tesserae.
There is a long history of ceramic art in almost all developed cultures, and often ceramic objects are all the artistic evidence left from vanished cultures, like that of the Nok in Africa over 2,000 years ago. Cultures especially noted for ceramics include the Chinese, Cretan, Greek, Persian, Mayan, Japanese, and Korean cultures, as well as the modern Western cultures. (Full article...)
Image 24Figure 1. Compliant bonding a gold wire (Click to enlarge view) Compliant bonding is used to connect gold wires to electrical components such as integrated circuit "chips". It was invented by Alexander Coucoulas in the 1960s. The bond is formed well below the melting point of the mating gold surfaces and is therefore referred to as a solid-state type bond. The compliant bond is formed by transmitting heat and pressure to the bond region through a relatively thick indentable or compliant medium, generally an aluminum tape (Figure 1). (Full article...)
The term anthropogenic designates an effect or object resulting from human activity. The term was first used in the technical sense by Russian geologist Alexey Pavlov, and it was first used in English by British ecologist Arthur Tansley in reference to human influences on climax plant communities. The atmospheric scientist Paul Crutzen introduced the term "Anthropocene" in the mid-1970s. The term is sometimes used in the context of pollution produced from human activity since the start of the Agricultural Revolution but also applies broadly to all major human impacts on the environment. Many of the actions taken by humans that contribute to a heated environment stem from the burning of fossil fuel from a variety of sources, such as: electricity, cars, planes, space heating, manufacturing, or the destruction of forests.

Image 2Brain-reading or thought identification uses the responses of multiple voxels in the brain evoked by stimulus then detected by fMRI in order to decode the original stimulus. Advances in research have made this possible by using human neuroimaging to decode a person's conscious experience based on non-invasive measurements of an individual's brain activity. Brain reading studies differ in the type of decoding (i.e. classification, identification and reconstruction) employed, the target (i.e. decoding visual patterns, auditory patterns, cognitive states), and the decoding algorithms (linear classification, nonlinear classification, direct reconstruction, Bayesian reconstruction, etc.) employed.
In 2024 -2025, professor of neuropsychology Barbara Sahakian qualified, "A lot of neuroscientists in the field are very cautious and say we can't talk about reading individuals' minds, and right now that is very true, but we're moving ahead so rapidly, it's not going to be that long before we will be able to tell whether someone's making up a story, or whether someone intended to do a crime with a certain degree of certainty."

An unmanned surface vehicle, unmanned surface vessel or uncrewed surface vessel (USV), colloquially called a drone boat, drone ship or sea drone, is a boat or ship that operates on the surface of the water without a crew. USVs operate with various levels of autonomy, from remote control to fully autonomous surface vehicles (ASV). (Full article...)
Image 4Industrial ecology (IE) is the study of material and energy flows through industrial systems. The globalindustrial economy can be modelled as a network of industrial processes that extract resources from the Earth and transform those resources into by-products, products and services which can be bought and sold to meet the needs of humanity. Industrial ecology seeks to quantify the material flows and document the industrial processes that make modern society function. Industrial ecologists are often concerned with the impacts that industrial activities have on the environment, with use of the planet's supply of natural resources, and with problems of waste disposal. Industrial ecology is a young but growing multidisciplinary field of research which combines aspects of engineering, economics, sociology, toxicology and the natural sciences.
Industrial ecology has been defined as a "systems-based, multidisciplinary discourse that seeks to understand emergent behavior of complex integrated human/natural systems". The field approaches issues of sustainability by examining problems from multiple perspectives, usually involving aspects of sociology, the environment, economy and technology. The name comes from the idea that the analogy of natural systems should be used as an aid in understanding how to design sustainable industrial systems. (Full article...)
Image 5Concept art of hyperloop inner workings
Hyperloop is a proposed high-speed transportation system for both passengers and freight. The concept behind the Hyperloop originated in the late 17th century with the invention of the world's first artificial vacuum, which led to designs for underground rapid transit systems powered by pneumatics in the decades that followed. In 1799, inventor George Medhurst proposed the idea to move goods through cast-iron pipes using air pressure and in 1844 built a railway station (for passenger carriages) in London that relied on pneumatics until 1847. In 2013, entrepreneur Elon Musk published a white paper, where the hyperloop was described as a transportation system using capsules supported by an air-bearing surface within a low-pressure tube. Hyperloop systems have three essential elements: tubes, pods, and terminals. The tube is a large, sealed low-pressure system (typically a long tunnel). The pod is a coach at atmospheric pressure that experiences low air resistance or friction inside the tube using magnetic propulsion (in the initial design, augmented by a ducted fan). The terminal handles pod arrivals and departures. The hyperloop, in the form proposed by Musk, differs from traditional vactrains by relying on residual air pressure inside the tube to provide lift from aerofoils and propulsion by fans; however, many subsequent variants using the name "hyperloop" have remained relatively close to the core principles of vactrains.
Hyperloop was teased by Elon Musk at a 2012 speaking event, and described as a "fifth mode of transport". Musk released details of an alpha-version in a white paper on 22 August 2013, in which the hyperloop design incorporated reduced-pressure tubes with pressurized capsules riding on air bearings driven by linear induction motors and axial compressors. The white paper showed an example hyperloop route running from the Los Angeles region to the San Francisco Bay Area, roughly following the Interstate 5 corridor. Some transportation analysts challenged the cost estimates in the white paper, with some predicting that a hyperloop would run several billion dollars higher. (Full article...)
Image 6 Uncrewed spacecraft or robotic spacecraft are spacecraft without people on board. Uncrewed spacecraft may have varying levels of autonomy from human input, such as remote control, or remote guidance. They may also be autonomous, in which they have a pre-programmed list of operations that will be executed unless otherwise instructed. A robotic spacecraft for scientific measurements is often called a space probe or space observatory.
Many space missions are more suited to telerobotic rather than crewed operation, due to lower cost and risk factors. In addition, some planetary destinations such as Venus or the vicinity of Jupiter are too hostile for human survival, given current technology. Outer planets such as Saturn, Uranus, and Neptune are too distant to reach with current crewed spaceflight technology, so telerobotic probes are the only way to explore them. Telerobotics also allows exploration of regions that are vulnerable to contamination by Earth micro-organisms since spacecraft can be sterilized. Humans can not be sterilized in the same way as a spaceship, as they coexist with numerous micro-organisms, and these micro-organisms are also hard to contain within a spaceship or spacesuit.

Google started selling a prototype of Google Glass to qualified "Glass Explorers" in the US on April 15, 2013, for a limited period for $1,500, before it became available to the public on May 15, 2014. It has an integrated 5 megapixel still/720p video camera. The headset received a great deal of criticism amid concerns that its use could violate existing privacy laws. (Full article...)
The new .50 BMG gun and improved scope could employ "fire-and-forget" technologies including "fin-stabilized projectiles, spin-stabilized projectiles, internal and/or external aero-actuation control methods, projectile guidance technologies, tamper proofing, small stable power supplies, and advanced sighting, optical resolution and clarity technologies". Its estimated availability at the time was 2015. (Full article...)
Image 10Comparison of parallax-barrier and lenticular autostereoscopic displays. Note: The figure is not to scale.
Autostereoscopy is any method of displaying stereoscopic images (adding binocular perception of 3D depth) without the use of special headgear, glasses, something that affects vision, or anything for eyes on the part of the viewer. Because headgear is not required, it is also called "glasses-free 3D" or "glassesless 3D".
There are two broad approaches currently used to accommodate motion parallax and wider viewing angles: eye-tracking, and multiple views so that the display does not need to sense where the viewer's eyes are located. Examples of autostereoscopic displays technology include lenticular lens, parallax barrier, and integral imaging. Volumetric and holographic displays are also autostereoscopic, as they produce a different image to each eye, although some do make a distinction between those types of displays that create a vergence-accommodation conflict and those that do not.

Image 11The vehicle The Ford Mach I, also known as the Ford Levacar Mach I, is a concept carhovercraft developed by the Ford Motor Company in the 1950s. The Mach I was a single-seat automobile which rode on pressurized air, not wheels. Its name was inspired by the speed Mach 1, an aspiration speed not yet achieved by vehicles at the time. It used air pressure at a force of 15–100 psi (100–690 kPa) to provide lift and propulsion. In experiments, 50–60 psi (340–410 kPa) was used so that 15 hp (11 kW) was needed for levitation and 2.5 hp (1.9 kW) propelled it 20 mph (32 km/h). An advertisement for the Mach I appeared in the magazine Boys' Life in 1960, in which it indicated the single-seater's dimensions: 94 in (2.4 m) long; 48 in (1.2 m) high; 54 in (1.4 m) wide.
The Levacar project was led by Andrew A. Kucher (a Ford Vice-President for Engineering and Research) and David J. Jay (a Senior Development Engineer). Kucher had initially conceived the concept around 1930. One of the lead designers was Gale Halderman, known for being the initial designer of the Ford Mustang. In addition to the Mach I automobile, the project also developed a similarly outfitted scooter, the Levascooter. In experiments on a circular track, vehicles would raise .125 inches (3.2 mm) off the ground and could jump 1 inch (25 mm) obstacles. (Full article...)
Image 12 Communication is commonly defined as the transmission of information. Its precise definition is disputed and there are disagreements about whether unintentional or failed transmissions are included and whether communication not only transmits meaning but also creates it. Models of communication are simplified overviews of its main components and their interactions. Many models include the idea that a source uses a coding system to express information in the form of a message. The message is sent through a channel to a receiver who has to decode it to understand it. The main field of inquiry investigating communication is called communication studies.
A common way to classify communication is by whether information is exchanged between humans, members of other species, or non-living entities such as computers. For human communication, a central contrast is between verbal and non-verbal communication. Verbal communication involves the exchange of messages in linguistic form, including spoken and written messages as well as sign language. Non-verbal communication happens without the use of a linguistic system, for example, using body language, touch, and facial expressions. Another distinction is between interpersonal communication, which happens between distinct persons, and intrapersonal communication, which is communication with oneself. Communicative competence is the ability to communicate well and applies to the skills of formulating messages and understanding them. (Full article...)
Augmented reality (AR) is an interactive experience that combines the real world and computer-generated 3D content. The content can span multiple sensory modalities, including visual, auditory, haptic, somatosensory and olfactory. AR can be defined as a system that incorporates three basic features: a combination of real and virtual worlds, real-time interaction, and accurate 3D registration of virtual and real objects. The overlaid sensory information can be constructive (i.e. additive to the natural environment), or destructive (i.e. masking of the natural environment). As such, it is one of the key technologies in the reality-virtuality continuum.
This experience is seamlessly interwoven with the physical world such that it is perceived as an immersive aspect of the real environment. In this way, augmented reality alters one's ongoing perception of a real-world environment, whereas virtual reality completely replaces the user's real-world environment with a simulated one.

Image 14Simplified view of a double-layer of negative ions in the electrode and solvated positive ions in the liquid electrolyte, separated by a layer of polarized solvent molecules
Every electrochemical capacitor has two electrodes, mechanically separated by a separator, which are ionically connected to each other via the electrolyte. The electrolyte is a mixture of positive and negative ions dissolved in a solvent such as water. At each of the two electrode surfaces originates an area in which the liquid electrolyte contacts the conductive metallic surface of the electrode. This interface forms a common boundary among two different phases of matter, such as an insoluble solid electrode surface and an adjacent liquid electrolyte. In this interface occurs a very special phenomenon of the double layer effect.
Applying a voltage to an electrochemical capacitor causes both electrodes in the capacitor to generate electrical double-layers. These double-layers consist of two layers of charges: one electronic layer is in the surface lattice structure of the electrode, and the other, with opposite polarity, emerges from dissolved and solvated ions in the electrolyte. The two layers are separated by a monolayer of solvent molecules, e.g., for water as solvent by water molecules, called inner Helmholtz plane (IHP). Solvent molecules adhere by physical adsorption on the surface of the electrode and separate the oppositely polarized ions from each other, and can be idealised as a molecular dielectric. In the process, there is no transfer of charge between electrode and electrolyte, so the forces that cause the adhesion are not chemical bonds, but physical forces, e.g., electrostatic forces. The adsorbed molecules are polarized, but, due to the lack of transfer of charge between electrolyte and electrode, suffered no chemical changes. (Full article...)
Image 15Life extension is the concept of extending the human lifespan, either modestly through improvements in medicine or dramatically by increasing the maximum lifespan beyond its generally-settled biological limit of around 125 years. Several researchers in the area, along with "life extensionists", "immortalists", or "longevists" (those who wish to achieve longer lives themselves), postulate that future breakthroughs in tissue rejuvenation, stem cells, regenerative medicine, molecular repair, gene therapy, pharmaceuticals, and organ replacement (such as with artificial organs or xenotransplantations) will eventually enable humans to have indefinite lifespans through complete rejuvenation to a healthy youthful condition (agerasia). The ethical ramifications, if life extension becomes a possibility, are debated by bioethicists.
The sale of purported anti-aging products such as supplements and hormone replacement is a lucrative global industry. For example, the industry that promotes the use of hormones as a treatment for consumers to slow or reverse the aging process in the US market generated about $50 billion of revenue a year in 2009. The use of such hormone products has not been proven to be effective or safe. (Full article...)
Image 17Software-defined radio (SDR) is a radio communication system where components that conventionally have been implemented in analog hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a computer or embedded system. While the concept of SDR is not new, the rapidly evolving capabilities of digital electronics render practical many processes which were once only theoretically possible.
A basic SDR system may consist of a computer equipped with a sound card, or other analog-to-digital converter, preceded by some form of RF front end. Significant amounts of signal processing are handed over to the general-purpose processor, rather than being done in special-purpose hardware (electronic circuits). Such a design produces a radio which can receive and transmit widely different radio protocols (sometimes referred to as waveforms) based solely on the software used. (Full article...)
Image 19Leica camera (1950s) A camera is an instrument used to capture and store images and videos, either digitally via an electronic image sensor, or chemically via a light-sensitive material such as photographic film. As a pivotal technology in the fields of photography and videography, cameras have played a significant role in the progression of visual arts, media, entertainment, surveillance, and scientific research. The invention of the camera dates back to the 19th century and has since evolved with advancements in technology, leading to a vast array of types and models in the 21st century.
Cameras function through a combination of multiple mechanical components and principles. These include exposure control, which regulates the amount of light reaching the sensor or film; the lens, which focuses the light; the viewfinder, which allows the user to preview the scene; and the film or sensor, which captures the image.

Making territorial claims in space is prohibited by international space law, defining space as a common heritage. International space law has had the goal to prevent colonial claims and militarization of space, and has advocated the installation of international regimes to regulate access to and sharing of space, particularly for specific locations such as the limited space of geostationary orbit or the Moon. To date, no permanent space settlement other than temporary space habitats have been established, nor has any extraterrestrial territory or land been internationally claimed. Currently there are also no plans for building a space colony by any government. However, many proposals, speculations, and designs, particularly for extraterrestrial settlements have been made through the years, and a considerable number of space colonization advocates and groups are active. Currently, the dominant private launch provider SpaceX, has been the most prominent organization planning space colonization on Mars, though having not reached a development stage beyond launch and landing systems.

Image 22Dummy unit illustrating the design of a BrainGate interface
A brain–computer interface (BCI), sometimes called a brain–machine interface (BMI), is a direct communication link between the brain's electrical activity and an external device, most commonly a computer or robotic limb. BCIs are often directed at researching, mapping, assisting, augmenting, or repairing human cognitive or sensory-motor functions. They are often conceptualized as a human–machine interface that skips the intermediary of moving body parts (hands...), although they also raise the possibility of erasing the distinction between brain and machine. BCI implementations range from non-invasive (EEG, MEG, MRI) and partially invasive (ECoG and endovascular) to invasive (microelectrode array), based on how physically close electrodes are to brain tissue.
Research on BCIs began in the 1970s by Jacques Vidal at the University of California, Los Angeles (UCLA) under a grant from the National Science Foundation, followed by a contract from the Defence Advanced Research Projects Agency (DARPA). Vidal's 1973 paper introduced the expression brain–computer interface into scientific literature. (Full article...)
Image 23Vyommitra (Indian Space Research Organisation, 2020) A gynoid, or fembot, is a femininehumanoid robot. Gynoids appear widely in science fiction films and arts. As more realistic humanoid robot design becomes technologically possible, they are also emerging in real-life robot design. Just like any other robot, the main parts of a gynoid include sensors, actuators and a control system. Sensors are responsible for detecting the changes in the environment while the actuators, also called effectors, are motors and other components responsible for the movement and control of the robot. The control system instructs the robot on what to do so as to achieve the desired results. (Full article...)
Image 24A smart contract is a computer program or a transaction protocol that is intended to automatically execute, control or document events and actions according to the terms of a contract or an agreement. The objectives of smart contracts are the reduction of need for trusted intermediators, arbitration costs, and fraud losses, as well as the reduction of malicious and accidental exceptions. Smart contracts are commonly associated with cryptocurrencies, and the smart contracts introduced by Ethereum are generally considered a fundamental building block for decentralized finance (DeFi) and non-fungible token (NFT) applications.
Image 25Throughout the past decade in the field of tissue engineering, novel cell sources, engineering materials, and tissue architecture techniques have provided engineering tissues that better restore, maintain, improve, or replace biological tissues. Tissue engineering is a biomedical engineering discipline that uses a combination of cells, engineering, materials methods, and suitable biochemical and physicochemical factors to restore, maintain, improve, or replace different types of biological tissues. Tissue engineering often involves the use of cells placed on tissue scaffolds in the formation of new viable tissue for a medical purpose, but is not limited to applications involving cells and tissue scaffolds. While it was once categorized as a sub-field of biomaterials, having grown in scope and importance, it can be considered as a field of its own. While most definitions of tissue engineering cover a broad range of applications, in practice, the term is closely associated with applications that repair or replace portions of or whole tissues (i.e. organs, bone, cartilage, blood vessels, bladder, skin, muscle etc.). Often, the tissues involved require certain mechanical and structural properties for proper functioning. The term has also been applied to efforts to perform specific biochemical functions using cells within an artificially-created support system (e.g. an artificial pancreas, or a bio artificial liver). The term regenerative medicine is often used synonymously with tissue engineering, although those involved in regenerative medicine place more emphasis on the use of stem cells or progenitor cells to produce tissues.

While the ability to deliberately engineer pathogens has been constrained to high-end labs run by top researchers, the technology to achieve this is rapidly becoming cheaper and more widespread. For example, the diminishing cost of sequencing the human genome (from $10 million to $1,000), the accumulation of large datasets of genetic information, the discovery of gene drives, and the discovery of CRISPR. Biotechnology risk is therefore a credible explanation for the Fermi paradox. (Full article...)
One argument for the importance of this risk references how human beings dominate other species because the human brain possesses distinctive capabilities other animals lack. If AI were to surpass human intelligence and become superintelligent, it might become uncontrollable. Just as the fate of the mountain gorilla depends on human goodwill, the fate of humanity could depend on the actions of a future machine superintelligence.
The plausibility of existential catastrophe due to AI is widely debated. It hinges in part on whether AGI or superintelligence are achievable, the speed at which dangerous capabilities and behaviors emerge, and whether practical scenarios for AI takeovers exist. Concerns about superintelligence have been voiced by computer scientists and tech CEOs such as Geoffrey Hinton, Yoshua Bengio, Alan Turing, Elon Musk, and OpenAI CEO Sam Altman. In 2022, a survey of AI researchers with a 17% response rate found that the majority believed there is a 10 percent or greater chance that human inability to control AI will cause an existential catastrophe. In 2023, hundreds of AI experts and other notable figures signed a statement declaring, "Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war". Following increased concern over AI risks, government leaders such as United Kingdom prime ministerRishi Sunak and United Nations Secretary-GeneralAntónio Guterres called for an increased focus on global AI regulation.

Image 3Investment is traditionally defined as the "commitment of resources to achieve later benefits". If an investment involves money, then it can be defined as a "commitment of money to receive more money later". From a broader viewpoint, an investment can be defined as "to tailor the pattern of expenditure and receipt of resources to optimise the desirable patterns of these flows". When expenditures and receipts are defined in terms of money, then the net monetary receipt in a time period is termed cash flow, while money received in a series of several time periods is termed cash flow stream.
In finance, the purpose of investing is to generate a return on the invested asset. The return may consist of a capital gain (profit) or loss, realised if the investment is sold, unrealised capital appreciation (or depreciation) if yet unsold. It may also consist of periodic income such as dividends, interest, or rental income. The return may also include currency gains or losses due to changes in foreign currency exchange rates.
Investors generally expect higher returns from riskier investments. When a low-risk investment is made, the return is also generally low. Similarly, high risk comes with a chance of high losses. Investors, particularly novices, are often advised to diversify their portfolio. Diversification has the statistical effect of reducing overall risk. (Full article...)
Image 4Solid waste after being shredded to a uniform size Waste (or wastes) are unwanted or unusable materials. Waste is any substance discarded after primary use, or is worthless, defective and of no use. A by-product, by contrast is a joint product of relatively minor economic value. A waste product may become a by-product, joint product or resource through an invention that raises a waste product's value above zero.
In most countries, such trade represents a significant share of gross domestic product (GDP). While international trade has existed throughout history (for example Uttarapatha, Silk Road, Amber Road, salt roads), its economic, social, and political importance has been on the rise in recent centuries.
Carrying out trade at an international level is a complex process when compared to domestic trade. When trade takes place between two or more states, factors like currency, government policies, economy, judicial system, laws, and markets influence trade. (Full article...)
The prerequisites for the crisis were complex. During the 1990s, the U.S. Congress had passed legislation intended to expand affordable housing through looser financing. In 1999, parts of the Glass–Steagall legislation (passed in 1933) were repealed, permitting institutions to mix low-risk operations, such as commercial banking and insurance, with higher-risk operations such as investment banking and proprietary trading. As the Federal Reserve ("Fed") lowered the federal funds rate from 2000 to 2003, institutions increasingly targeted low-income homebuyers, largely belonging to racial minorities, with high-risk loans; this development went unattended by regulators. As interest rates rose from 2004 to 2006, the cost of mortgages rose and the demand for housing fell, causing property values to decline. In early 2007, as more U.S. mortgage holders began defaulting on their repayments, subprime lenders went bankrupt, culminating in April with the bankruptcy of New Century Financial. As demand and prices continued to fall, the contagion spread to worldwide credit markets by August, and central banks began injecting liquidity. By July 2008, Fannie Mae and Freddie Mac, companies which together owned or guaranteed half of the U.S. housing market, were on the verge of collapse; the Housing and Economic Recovery Act enabled the government to take over and cover their combined $1.6 trillion debt on September 7.
Image 8Early in the COVID-19 pandemic, convention centers (pictured here) were deemed to be ideal sites for temporary hospitals, due to their existing infrastructure (electrical, water, sewage). Hotels and dormitories were also considered appropriate because they can use negative pressure technology.
A pandemic (/pænˈdɛmɪk/pan-DEM-ik) is an epidemic of an infectious disease that has a sudden increase in cases and spreads across a large region, for instance multiple continents or worldwide, affecting a substantial number of individuals. Widespread endemic diseases with a stable number of infected individuals such as recurrences of seasonal influenza are generally excluded as they occur simultaneously in large regions of the globe rather than being spread worldwide.
Throughout human history, there have been a number of pandemics of diseases such as smallpox. The Black Death, caused by the Plague, caused the deaths of up to half of the population of Europe in the 14th century. The term pandemic had not been used then, but was used for later epidemics, including the 1918 H1N1 influenza A pandemic—more commonly known as the Spanish flu—which is the deadliest pandemic in history. The most recent pandemics include the HIV/AIDS pandemic, the 2009 swine flu pandemic and the COVID-19 pandemic. Almost all these diseases still circulate among humans though their impact now is often far less.
Unemployment, according to the OECD (Organisation for Economic Co-operation and Development), is the proportion of people above a specified age (usually 15) not being in paid employment or self-employment but currently available for work during the reference period.
Unemployment is measured by the unemployment rate, which is the number of people who are unemployed as a percentage of the labour force (the total number of people employed added to those unemployed).
Unemployment can have many sources, such as the following: (Full article...)
Image 10Global distribution of dryland areas based on the aridity index computed over a 30-year average during 1981 to 2010. Typical deserts are indicated by the hyper-arid category (light yellow). Desertification is a type of gradual land degradation of fertile land into arid desert due to a combination of natural processes and human activities.
The immediate cause of desertification is the loss of most vegetation. This is driven by a number of factors, alone or in combination, such as drought, climatic shifts, tillage for agriculture, overgrazing and deforestation for fuel or construction materials. Though vegetation plays a major role in determining the biological composition of the soil, studies have shown that, in many environments, the rate of erosion and runoff decreases exponentially with increased vegetation cover. Unprotected, dry soil surfaces blow away with the wind or are washed away by flash floods, leaving infertile lower soil layers that bake in the sun and become an unproductive hardpan. This spread of arid areas is caused by a variety of factors, such as overexploitation of soil as a result of human activity and the effects of climate change.
At least 90% of the inhabitants of drylands live in developing countries, where they also suffer from poor economic and social conditions. This situation is exacerbated by land degradation because of the reduction in productivity, the precariousness of living conditions and the difficulty of access to resources and opportunities.

Image 11Tar sands in Alberta, 2008. Oil is one of the most used resources by humans. Resource depletion is the consumption of a resource faster than it can be replenished. Natural resources are commonly divided between renewable resources and non-renewable resources. The use of either of these forms of resources beyond their rate of replacement is considered to be resource depletion. The value of a resource is a direct result of its availability in nature and the cost of extracting the resource. The more a resource is depleted the more the value of the resource increases. There are several types of resource depletion, including but not limited to: mining for fossil fuels and minerals, deforestation, pollution or contamination of resources, wetland and ecosystem degradation, soil erosion, overconsumption, aquifer depletion, and the excessive or unnecessary use of resources. Resource depletion is most commonly used in reference to farming, fishing, mining, water usage, and the consumption of fossil fuels. Depletion of wildlife populations is called defaunation.
Resource depletion also brings up topics regarding its history, specifically its roots in colonialism and the Industrial Revolution, depletion accounting, and the socioeconomic impacts of resource depletion, as well as the morality of resource consumption, how humanity will be impacted and what the future will look like if resource depletion continues at the current rate, Earth Overshoot Day, and when specific resources will be completely exhausted.

Image 13Human overpopulation (or human population overshoot) is the idea that human populations may become too large to be sustained by their environment or resources in the long term. The topic is usually discussed in the context of world population, though it may concern individual nations, regions, and cities.
Since 1804, the global living human population has increased from 1 billion to 8 billion due to medical advancements and improved agricultural productivity. Annual world population growth peaked at 2.1% in 1968 and has since dropped to 1.1%. According to the most recent United Nations' projections, the global human population is expected to reach 9.7 billion in 2050 and would peak at around 10.4 billion people in the 2080s, before decreasing, noting that fertility rates are falling worldwide. Other models agree that the population will stabilize before or after 2100. Conversely, other researchers have found that national birth registries data from 2022 and 2023 that cover half the world's population indicate that the 2022 UN projections overestimated fertility rates by 10 to 20% and are already outdated, that the global fertility rate has possibly already fallen below the sub-replacement fertility level for the first time in human history, and that the global population will peak at approximately 9.5 billion by 2061. The 2024 UN projections report estimated that world population would peak at 10.29 billion in 2084 and decline to 10.18 billion by 2100, which was 6% lower than the UN had estimated in 2014.
Image 14Gray goo (also spelled as grey goo) is a hypothetical global catastrophic scenario involving molecular nanotechnology in which out-of-control self-replicating machines consume all biomass (and perhaps also everything else) on Earth while building many more of themselves, a scenario that has been called ecophagy (the literal consumption of the ecosystem). The original idea assumed machines were designed to have this capability, while popularizations have assumed that machines might somehow gain this capability by accident.
Self-replicating machines of the macroscopic variety were originally described by mathematician John von Neumann, and are sometimes referred to as von Neumann machines or clanking replicators. The term gray goo was coined by nanotechnology pioneer K. Eric Drexler in his 1986 book Engines of Creation. In 2004, he stated "I wish I had never used the term 'gray goo'." Engines of Creation mentions "gray goo" as a thought experiment in two paragraphs and a note, while the popularized idea of gray goo was first publicized in a mass-circulation magazine, Omni, in November 1986.

Image 15Summary of major environmental-change categories that cause biodiversity loss. The data is expressed as a percentage of human-driven change (in red) relative to baseline (blue), as of 2021. Red indicates the percentage of the category that is damaged, lost, or otherwise affected, whereas blue indicates the percentage that is intact, remaining, or otherwise unaffected. Biodiversity loss happens when plant or animal species disappear completely from Earth (extinction) or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent. It is temporary if the damage that led to the loss is reversible in time, for example through ecological restoration. If this is not possible, then the decrease is permanent. The cause of most of the biodiversity loss is, generally speaking, human activities that push the planetary boundaries too far. These activities include habitat destruction (for example deforestation) and land use intensification (for example monoculture farming). Further problem areas are air and water pollution (including nutrient pollution), over-exploitation, invasive species and climate change.
Climate change is another threat to global biodiversity. For example, coral reefs—which are biodiversity hotspots—will be lost by the year 2100 if global warming continues at the current rate. Still, it is the general habitat destruction (often for expansion of agriculture), not climate change, that is currently the bigger driver of biodiversity loss. Invasive species and other disturbances have become more common in forests in the last several decades. These tend to be directly or indirectly connected to climate change and can cause a deterioration of forest ecosystems. (Full article...)
Access to health care may vary across countries, communities, and individuals, influenced by social and economic conditions and health policies. Providing health care services means "the timely use of personal health services to achieve the best possible health outcomes". Factors to consider in terms of health care access include financial limitations (such as insurance coverage), geographical and logistical barriers (such as additional transportation costs and the ability to take paid time off work to use such services), sociocultural expectations, and personal limitations (lack of ability to communicate with health care providers, poor health literacy, low income). Limitations to health care services affect negatively the use of medical services, the efficacy of treatments, and overall outcome (well-being, mortality rates).
Health systems are the organizations established to meet the health needs of targeted populations. According to the World Health Organization (WHO), a well-functioning health care system requires a financing mechanism, a well-trained and adequately paid workforce, reliable information on which to base decisions and policies, and well-maintained health facilities to deliver quality medicines and technologies.

Image 18The distribution of atmospheric ozone in partial pressure as a function of altitude Ozone depletion consists of two related events observed since the late 1970s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere, and a much larger springtime decrease in stratospheric ozone (the ozone layer) around Earth's polar regions. The latter phenomenon is referred to as the ozone hole. There are also springtime polar tropospheric ozone depletion events in addition to these stratospheric events.
The main causes of ozone depletion and the ozone hole are manufactured chemicals, especially manufactured halocarbonrefrigerants, solvents, propellants, and foam-blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons), referred to as ozone-depleting substances (ODS). These compounds are transported into the stratosphere by turbulent mixing after being emitted from the surface, mixing much faster than the molecules can settle. Once in the stratosphere, they release atoms from the halogen group through photodissociation, which catalyze the breakdown of ozone (O3) into oxygen (O2). Both types of ozone depletion were observed to increase as emissions of halocarbons increased.
Ozone depletion and the ozone hole have generated worldwide concern over increased cancer risks and other negative effects. The ozone layer prevents harmful wavelengths of ultraviolet (UVB) light from passing through the Earth's atmosphere. These wavelengths cause skin cancer, sunburn, permanent blindness, and cataracts, which were projected to increase dramatically as a result of thinning ozone, as well as harming plants and animals. These concerns led to the adoption of the Montreal Protocol in 1987, which bans the production of CFCs, halons, and other ozone-depleting chemicals. Over time, scientists have developed new refrigerants with lower global warming potential (GWP) to replace older ones. For example, in new automobiles, R-1234yf systems are now common, being chosen over refrigerants with much higher GWP such as R-134a and R-12. (Full article...)
The origins of the Internet date back to research that enabled the time-sharing of computer resources, the development of packet switching in the 1960s and the design of computer networks for data communication. The set of rules (communication protocols) to enable internetworking on the Internet arose from research and development commissioned in the 1970s by the Defense Advanced Research Projects Agency (DARPA) of the United States Department of Defense in collaboration with universities and researchers across the United States and in the United Kingdom and France. The ARPANET initially served as a backbone for the interconnection of regional academic and military networks in the United States to enable resource sharing. The funding of the National Science Foundation Network as a new backbone in the 1980s, as well as private funding for other commercial extensions, encouraged worldwide participation in the development of new networking technologies and the merger of many networks using DARPA's Internet protocol suite. The linking of commercial networks and enterprises by the early 1990s, as well as the advent of the World Wide Web, marked the beginning of the transition to the modern Internet, and generated sustained exponential growth as generations of institutional, personal, and mobilecomputers were connected to the internetwork. Although the Internet was widely used by academia in the 1980s, the subsequent commercialization of the Internet in the 1990s and beyond incorporated its services and technologies into virtually every aspect of modern life.

Biodiversity loss happens when plant or animal species disappear completely from Earth (extinction) or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent. It is temporary if the damage that led to the loss is reversible in time, for example through ecological restoration. If this is not possible, then the decrease is permanent. The cause of most of the biodiversity loss is, generally speaking, human activities that push the planetary boundaries too far. These activities include habitat destruction (for example deforestation) and land use intensification (for example monoculture farming). Further problem areas are air and water pollution (including nutrient pollution), over-exploitation, invasive species and climate change.
Climate change is another threat to global biodiversity. For example, coral reefs—which are biodiversity hotspots—will be lost by the year 2100 if global warming continues at the current rate. Still, it is the general habitat destruction (often for expansion of agriculture), not climate change, that is currently the bigger driver of biodiversity loss. Invasive species and other disturbances have become more common in forests in the last several decades. These tend to be directly or indirectly connected to climate change and can cause a deterioration of forest ecosystems. (Full article...)
Image 21Women selling produce at a market in Lilongwe, Malawi Food security is the state of having reliable access to a sufficient quantity of affordable, nutritious food. The availability of food for people of any class and state, gender or religion is another element of food security. Similarly, household food security is considered to exist when all the members of a family, at all times, have access to enough food for an active, healthy life. Individuals who are food-secure do not live in hunger or fear of starvation. Food security includes resilience to future disruptions of food supply. Such a disruption could occur due to various risk factors such as droughts and floods, shipping disruptions, fuel shortages, economic instability, and wars. Food insecurity is the opposite of food security: a state where there is only limited or uncertain availability of suitable food.
The concept of food security has evolved over time. The four pillars of food security include availability, access, utilization, and stability. In addition, there are two more dimensions that are important: agency and sustainability. These six dimensions of food security are reinforced in conceptual and legal understandings of the right to food. The World Food Summit in 1996 declared that "food should not be used as an instrument for political and economic pressure."
Virtually all civilizations have suffered such a fate, regardless of their size or complexity. Most never recovered, such as the Western and Eastern Roman Empires, the Maya civilization, and the Easter Island civilization. However, some of them later revived and transformed, such as China, Greece, and Egypt.
Anthropologists, historians, and sociologists have proposed a variety of explanations for the collapse of civilizations involving causative factors such as environmental degradation, depletion of resources, costs of rising complexity, invasion, disease, decay of social cohesion, growing inequality, extractive institutions, long-term decline of cognitive abilities, loss of creativity, and misfortune. However, complete extinction of a culture is not inevitable, and in some cases, the new societies that arise from the ashes of the old one are evidently its offspring, despite a dramatic reduction in sophistication. Moreover, the influence of a collapsed society, such as the Western Roman Empire, may linger on long after its death. (Full article...)
Image 23Deforestation of the Amazon rainforest in Brazil's Maranhão state, 2016 Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, with half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. Estimates vary widely as to the extent of deforestation in the tropics. In 2019, nearly a third of the overall tree cover loss, or 3.8 million hectares, occurred within humid tropical primary forests. These are areas of mature rainforest that are especially important for biodiversity and carbon storage.
Besides the immediate destruction of cities by nuclear blasts, the potential aftermath of a nuclear war could involve firestorms, a nuclear winter, widespread radiation sickness from fallout, and/or the temporary (if not permanent) loss of much modern technology due to electromagnetic pulses. Some scientists, such as Alan Robock, have speculated that a thermonuclear war could result in the end of modern civilization on Earth, in part due to a long-lasting nuclear winter. In one model, the average temperature of Earth following a full thermonuclear war falls for several years by 7 – 8 °C (13 to 15 degrees Fahrenheit) on average.
Early Cold War-era studies suggested that billions of humans would survive the immediate effects of nuclear blasts and radiation following a global thermonuclear war. The International Physicians for the Prevention of Nuclear War believe that nuclear war could indirectly contribute to human extinction via secondary effects, including environmental consequences, societal breakdown, and economic collapse.

Image 2The Leaning Tower of Pisa is the freestanding bell tower of the Cathedral of Pisa, Italy. The third oldest structure in the city's Square of Miracles, it is known worldwide for its unintended tilt. The tower's tilt began during construction in the 12th century, caused by an inadequate foundation on ground too soft on one side to properly support the structure's weight. The tilt gradually increased until the tower was stabilized (and the tilt partially corrected) by efforts in the late 20th and early 21st centuries. The tower, which measures 55.86 metres (183.27 feet) from the ground on the low side and 56.67 metres (185.93 feet) on the high side, has been listed as a UNESCO World Heritage Site since 1987.
Image 3An animation of a cicada undergoing ecdysis, the molting of the exoskeleton in arthropods and related groups. Since the cuticula of these animals is inelastic, it is shed during growth and a new, larger covering is formed. The old, empty exoskeleton is called an exuvia. Within one or two hours, the cuticle hardens and darkens, during which time the animal grows, since growth is otherwise constrained by the rigidity of the exoskeleton. Each frame of this image was taken at one-minute intervals, with a 30-minute gap in middle while the cicada rested. The entire process took about 2 hours to complete.
Image 4The Pinwheel Galaxy is a face-on spiral galaxy located 21 million light-years away in the constellationUrsa Major. It was first discovered by Pierre Méchain on March 27, 1781, and communicated to Charles Messier, who verified its position for inclusion in the Messier Catalogue as one of its final entries. This image, released on February 28, 2006, is composed of 51 individual exposures, as well as some extra ground-based photos. At the time of its release, it was the largest and most detailed image of a galaxy by the Hubble Space Telescope.
Image 6The International Space Station (ISS) as seen from the Space Shuttle Endeavour. Zarya, the first module of the ISS launched in 1998, is seen in the foreground. Since then, twenty-six Space Shuttle flights have docked with the ISS to assemble various other modules and components, which include four pairs of solar arrays seen on each side.
Image 8An overhead view of Skylab, the United States' first space station, in Earth orbit as photographed from the Skylab 4 Command and Service Modules. Skylab 4 was the last mission to Skylab and brought back its final crew; this photograph was the last one taken of the station before the mission re-entered Earth's atmosphere and disintegrated in 1979.

Image 11The American Bison, or Buffalo, is the largest terrestrial mammal in North America, and once inhabited the Great Plains in massive herds. They were central to the lives of Native American tribes. This pile of bison skulls from the 1870s illustrates the extent of their slaughter in the 19th century by settlers: from a population of about 60 million in 1800 to as few as 750 in 1890. They have since been reintroduced into the wild and are no longer considered a high risk endangered species.
Image 13A neutral density filter is a filter that reduces or modifies the intensity of all wavelengths or colors of light equally, giving no changes in hue of color rendition. The filter reduces the amount of light entering the lens, allowing the photographer to select combinations of aperture, exposure time and sensor sensitivity to avoid overexposed pictures. It would normally be attached to the lens, but is hand-held here to illustrate the effect.
Image 16A dust storm rushes towards a military camp as it rolls over Al Asad Airbase, Iraq, just before nightfall on April 27, 2005. A dust storm (or sandstorm) is a meteorological phenomenon common in dry, arid and semi-arid regions, usually the result of convection currents created by intense heating of the ground. These currents then carry clouds of sand over large distances.

Image 20The Aqueduct of Segovia is a Roman aqueduct located in Segovia, Spain that transports water from the Rio Frio. It is thought to have been constructed during the 1st century CE. One of the most significant and best-preserved ancient monuments left on the Iberian Peninsula, the aqueduct is considered a symbol of Segovia and is present on the city's coat of arms.
Image 22The I-35W Mississippi River bridge was an eight-lane, steel truss arch bridge that carried Interstate 35W across the Saint Anthony Falls of the Mississippi River in Minneapolis, Minnesota. Once the third-busiest bridge in the state, it suddenly collapsed on August 1, 2007, killing 13 and injuring 145. Rescue of people stranded on the bridge was complete in three hours, while recovery of bodies—involving 75 local, state and federal agencies—took three weeks. An NTSB investigation cited a design flaw as the likely cause of the collapse, noting that a too-thin gusset plate ripped along a line of rivets.
Image 23Devastation caused by Hurricane Katrina in New Orleans, Louisiana during 2005, shown here looking down on Interstate 10 at West End Boulevard towards Lake Pontchartrain. Over 1,800 people were confirmed dead with 705 still missing. It was the costliest Atlantic hurricane in history causing around $86 billion in damage. This photo shows flooded roadways as the United States Coast Guard conducted initial damage assessment overflights of New Orleans on Monday, August 29, 2005. The city flooded due primarily to the failure of the levee system. Many who remained in their homes had to swim for their lives, wade through deep water, or remain trapped in their attics or on their rooftops.
Image 24A man engaging in big wave surfing at Mavericks, located just north of Half Moon Bay, California. Big wave surfing is a discipline within surfing in which experienced surfers paddle into or are towed onto waves which are at least 20 ft (6.1 m) high, and is a hazardous activity, as surfers can be pushed far beneath the surface of the water after a wipeout.
Image 25San Francisco Bay shrouded in fog, as seen from the Marin Headlands looking east. The fog of San Francisco is a kind of sea fog, created when warm, moist air blows from the central Pacific Ocean across the cold water of the California Current, which flows just off the coast. The water is cold enough to lower the temperature of the air to the dew point, causing fog generation. In this photo, the towers of the Golden Gate Bridge can be seen poking through the fog, and the Bay Bridge is visible in the distance.
Image 28The Door to Hell is a natural gas field in Derweze, Turkmenistan, which has been burning since 1971 when it was ignited by Soviet scientists who expected it to burn out within days. They were trying to prevent the release of poisonous gases. The name "Door to Hell" was given to the field by locals. The hot spots range over an area with a width of 60 metres (200 ft) and to a depth of about 20 metres (66 ft).
Image 29Sandboarding is a boardsport similar to snowboarding, but competitions take place on sand dunes rather than snow-covered mountains. Here, a member of the US Navy sandboards down a dune in Jebel Ali, Dubai.
Image 31A lava lake at Mount Nyiragongo, a volcano found in Virunga National Park in the Democratic Republic of the Congo. Lava lakes, which can form in three different ways, are large volumes of molten lava, usually basaltic, contained in a volcanic vent, crater, or broad depression. Persistent lava lakes such as the one at Nyiragongo, which is the largest to appear in recent times, are rare.
Image 32The Hubble Extreme Deep Field is an image of a small area of space in the constellation Fornax released by NASA on September 25, 2012. The successor to the Hubble Ultra-Deep Field, this image was compiled from 10 years of previous images with a total exposure time of two million seconds, or approximately 23 days.
Image 34Lucky Diamond Rich (b. 1971) is a New Zealand-born performance artist and street performer who holds the Guinness World Record for most tattooed man, taking the title from Tom Leppard in 2006. He is recognized by Guinness as being covered in tattoos over 100% of his body, including the inside of his eyelids, ears, and mouth.
Image 35A swan created using modular origami, a paperfolding technique which uses two or more sheets of paper to create a larger and more complex structure than possible with single-piece origami techniques. Each individual sheet of paper is folded into a module, or unit, and then modules are assembled into an integrated flat shape or three-dimensional structure by inserting flaps into pockets created by the folding process. These insertions create tension or friction that holds the model together.
Image 39One of two monkey selfies taken by Celebes crested macaques using equipment belonging to the British nature photographer David Slater. In mid-2014, the images' hosting on Wikimedia Commons was at the centre of a dispute over whether copyright could be held on artworks made by non-human animals. Slater argued that, as he had "engineered" the shot, he held copyright, while Wikimedia considered the photographs public domain on the grounds that they were made by an animal rather than a person. In December 2014, the United States Copyright Office stated that works by a non-human are not subject to US copyright, a view reaffirmed by a US federal judge in 2016.
Image 40NGC 1300 is a barred spiral galaxy located roughly 69 million light-years away in the direction of the constellation Eridanus. In its core, the nucleus shows its own extraordinary and distinct "grand-design" spiral structure that is about 3,300 light-years long.
Image 41Glaucus atlanticus is a species of small, blue sea slug. This pelagic aeolid nudibranch floats upside down, using the surface tension of the water to stay up, and is carried along by the winds and ocean currents. The blue side of their body faces upwards, blending in with the blue of the water, while the grey side faces downwards, blending in with the silvery surface of the sea. G. atlanticus feeds on other pelagic creatures, including the Portuguese man o' war.

Wow! Thanks for your help on the Future studies project. I can't believe all the pages you've contributed to, but glad you found ours!... RealFuturist (talk) 17:09, 3 February 2012 (UTC)
Many years ago, back before I had created my current account, I created a humble little userspace navigation menu based off of two of your menus from the User Page Design Center (initially 15, but ultimately 6). Over the years it has grown, but I don't know if I ever would have started it without seeing your menus first. I just want to thank you for putting the effort into creating those menus and then sharing them at the Design Center where they have been helpful for people like me. I hope you don't mind me borrowing from your hard work! Thanks again and take care! Michael Barera (talk) 03:30, 13 January 2013 (UTC)

Thank you for being one of Misplaced Pages's top medical contributors!
please help translate this message into the local language
In 2015 you were one of the top 300 medical editors across any language of Misplaced Pages. Thank you from Wiki Project Med Foundation for helping bring free, complete, accurate, up-to-date health information to the public. We really appreciate you and the vital work you do! Wiki Project Med Foundation is a user group whose mission is to improve our health content. Consider joining here, there are no associated costs, and we would love to collaborate further.
Hi there! I just wanted to let you know that I think your planet outlines are really cool. I have long thought it was a shame that only Wikipedians seem to know about Books or Portals, because they are really great tools for structuring knowledge (while everyone loves diving down the Misplaced Pages rabbit hole, we could really do with some better content organization). The outlines strike me as a great way to bring that sort content organization to mainspace, where it will actually reach a large number of readers. I notice that I am the first one to edit them besides yourself, and I hope you know that I do so with love.
What a Brilliant Idea Barnstar
Great idea with the outline articles - a great solution to a need for better mainspace-based content structuring! I see from WP:Outlines that you actually came up with this concept some years ago, but this is the first I've noticed it. A2soup (talk) 02:46, 8 February 2017 (UTC)

The Portal Barnstar
The Portal Barnstar is awarded to Wikipedians who have made significant contributions to topic portals. Awarded to Transhumanist for his overly enthusiastic efforts regarding the portal system and WikiProject Portals. – Lionel 11:02, 30 April 2018 (UTC)
Transhumanist, thank you for your extraordinary efforts on behalf of portals. It reminds me of the time when a series of attacks on scientific bibliographies led to the formation of WikiProject Bibliographies. I don't understand why your detractors are so passionate about deleting portals, but your actions have been a model for how to deal with an attack constructively. RockMagnetist(talk) 16:10, 5 May 2018 (UTC)

The Article Rescue Barnstar
May all who see this barnstar know that The Transhumanist made a valiant and commendable effort for defending the portal namespace from deletion. It preserved countless hours of work initially invested into creating the content. Moreoever, The Transhumanist, is doing a yeoman's job in attempting to improve the content within with portal namespace. RightCowLeftCoast (talk) 00:24, 26 May 2018 (UTC)
@RightCowLeftCoast: Thank you. I feel honored. Please keep in mind that I have not been working alone. Credit goes to the nearly 400 editors who came forward to speak up for the keeping of portals. And although the RfC to delete all portals is over, the job of defending portals from deletion is not. For the portal namespace to be retained in the long term, the portals in it will need to be improved to a worthy quality level, otherwise we may see more deletion attempts. This task is far more than a single editor can handle. Fortunately, many editors have come forward to meet the challenge. Working to develop portals and the entire portal system, is a team of 80 editors who are diligently redesigning, upgrading, updating, and maintaining portals. They are the members of the Portals WikiProject, and without them there might be no portals. They are doing a wonderful job, and I am very proud of them. Thank you. — The Transhumanist 17:22, 26 May 2018 (UTC)
Thank you for your thoughts and efforts regarding portals, for the concept of outlines, for sectional redirects, for articles such as Life Extension Foundation, for service from 2006, including portal philosophy and user page design center, - repeating (1 & 4 June 2009): you are an awesome Wikipedian!
Thank you. I looked, but couldn't figure out what 1 & 4 June 2009 were referring to. Just curious. — The Transhumanist 19:26, 4 June 2018 (UTC)

Image 2The Leaning Tower of Pisa is the freestanding bell tower of the Cathedral of Pisa, Italy. The third oldest structure in the city's Square of Miracles, it is known worldwide for its unintended tilt. The tower's tilt began during construction in the 12th century, caused by an inadequate foundation on ground too soft on one side to properly support the structure's weight. The tilt gradually increased until the tower was stabilized (and the tilt partially corrected) by efforts in the late 20th and early 21st centuries. The tower, which measures 55.86 metres (183.27 feet) from the ground on the low side and 56.67 metres (185.93 feet) on the high side, has been listed as a UNESCO World Heritage Site since 1987.
Image 3An animation of a cicada undergoing ecdysis, the molting of the exoskeleton in arthropods and related groups. Since the cuticula of these animals is inelastic, it is shed during growth and a new, larger covering is formed. The old, empty exoskeleton is called an exuvia. Within one or two hours, the cuticle hardens and darkens, during which time the animal grows, since growth is otherwise constrained by the rigidity of the exoskeleton. Each frame of this image was taken at one-minute intervals, with a 30-minute gap in middle while the cicada rested. The entire process took about 2 hours to complete.
Image 4The Pinwheel Galaxy is a face-on spiral galaxy located 21 million light-years away in the constellation Ursa Major. It was first discovered by Pierre Méchain on March 27, 1781, and communicated to Charles Messier, who verified its position for inclusion in the Messier Catalogue as one of its final entries. This image, released on February 28, 2006, is composed of 51 individual exposures, as well as some extra ground-based photos. At the time of its release, it was the largest and most detailed image of a galaxy by the Hubble Space Telescope.
Image 5Astronaut Buzz Aldrin saluting the flag of the United States, part of the Lunar Flag Assembly, during Apollo 11. The Lunar Flag Assembly was designed to survive a Moon landing and to appear to "wave" as it would in a breeze on Earth. This flag fell over when the Lunar Module Eagle took off.
Image 6The International Space Station (ISS) as seen from the Space Shuttle Endeavour. Zarya, the first module of the ISS launched in 1998, is seen in the foreground. Since then, twenty-six Space Shuttle flights have docked with the ISS to assemble various other modules and components, which include four pairs of solar arrays seen on each side.

SPIE involves either a person or goods being lowered from or raised to a helicopter via a cable above terrain on which landing would be difficult.
Image 8An overhead view of Skylab, the United States' first space station, in Earth orbit as photographed from the Skylab 4 Command and Service Modules. Skylab 4 was the last mission to Skylab and brought back its final crew; this photograph was the last one taken of the station before the mission re-entered Earth's atmosphere and disintegrated in 1979.

Image 11The American Bison, or Buffalo, is the largest terrestrial mammal in North America, and once inhabited the Great Plains in massive herds. They were central to the lives of Native American tribes. This pile of bison skulls from the 1870s illustrates the extent of their slaughter in the 19th century by settlers: from a population of about 60 million in 1800 to as few as 750 in 1890. They have since been reintroduced into the wild and are no longer considered a high risk endangered species.
Image 12The mushroom cloud from the Ivy Mike nuclear test, one of two tests conducted as part of Operation Ivy at the Pacific Proving Grounds on Elugelab in the Marshall Islands. Mike was the first successful full-scale test of a multi-megaton thermonuclear weapon, and it left an underwater crater 6,240 ft (1,900 m) wide and 164 ft (50 m) deep where the island had been.
Image 13A neutral density filter is a filter that reduces or modifies the intensity of all wavelengths or colors of light equally, giving no changes in hue of color rendition. The filter reduces the amount of light entering the lens, allowing the photographer to select combinations of aperture, exposure time and sensor sensitivity to avoid overexposed pictures. It would normally be attached to the lens, but is hand-held here to illustrate the effect.

Image 16A dust storm rushes towards a military camp as it rolls over Al Asad Airbase, Iraq, just before nightfall on April 27, 2005. A dust storm (or sandstorm) is a meteorological phenomenon common in dry, arid and semi-arid regions, usually the result of convection currents created by intense heating of the ground. These currents then carry clouds of sand over large distances.

Image 22The I-35W Mississippi River bridge was an eight-lane, steel truss arch bridge that carried Interstate 35W across the Saint Anthony Falls of the Mississippi River in Minneapolis, Minnesota. Once the third-busiest bridge in the state, it suddenly collapsed on August 1, 2007, killing 13 and injuring 145. Rescue of people stranded on the bridge was complete in three hours, while recovery of bodies—involving 75 local, state and federal agencies—took three weeks. An NTSB investigation cited a design flaw as the likely cause of the collapse, noting that a too-thin gusset plate ripped along a line of rivets.
Image 23Devastation caused by Hurricane Katrina in New Orleans, Louisiana during 2005, shown here looking down on Interstate 10 at West End Boulevard towards Lake Pontchartrain. Over 1,800 people were confirmed dead with 705 still missing. It was the costliest Atlantic hurricane in history causing around $86 billion in damage. This photo shows flooded roadways as the United States Coast Guard conducted initial damage assessment overflights of New Orleans on Monday, August 29, 2005. The city flooded due primarily to the failure of the levee system. Many who remained in their homes had to swim for their lives, wade through deep water, or remain trapped in their attics or on their rooftops.
Image 24A man engaging in big wave surfing at Mavericks, located just north of Half Moon Bay, California. Big wave surfing is a discipline within surfing in which experienced surfers paddle into or are towed onto waves which are at least 20 ft (6.1 m) high, and is a hazardous activity, as surfers can be pushed far beneath the surface of the water after a wipeout.
Image 25San Francisco Bay shrouded in fog, as seen from the Marin Headlands looking east. The fog of San Francisco is a kind of sea fog, created when warm, moist air blows from the central Pacific Ocean across the cold water of the California Current, which flows just off the coast. The water is cold enough to lower the temperature of the air to the dew point, causing fog generation. In this photo, the towers of the Golden Gate Bridge can be seen poking through the fog, and the Bay Bridge is visible in the distance.
Image 26The "Baker" explosion, part of Operation Crossroads, a nuclear weapon test by the United States military at Bikini Atoll, Micronesia, on July 25, 1946. Its purpose was to test the effect of nuclear weapons on naval ships. It was the second US nuclear bomb set off since the bombing of Nagasaki.
Image 27Burj Khalifa is a skyscraper in Dubai, United Arab Emirates, and currently the tallest man-made structure in the world, at 829.8 m (2,722 ft). It was designed to be the centerpiece of a large-scale, mixed-use development known as Downtown Dubai. Construction took over five years, and the skyscraper was officially opened in January 2010.
Image 28The Door to Hell is a natural gas field in Derweze, Turkmenistan, which has been burning since 1971 when it was ignited by Soviet scientists who expected it to burn out within days. They were trying to prevent the release of poisonous gases. The name "Door to Hell" was given to the field by locals. The hot spots range over an area with a width of 60 metres (200 ft) and to a depth of about 20 metres (66 ft).

Image 31A lava lake at Mount Nyiragongo, a volcano found in Virunga National Park in the Democratic Republic of the Congo. Lava lakes, which can form in three different ways, are large volumes of molten lava, usually basaltic, contained in a volcanic vent, crater, or broad depression. Persistent lava lakes such as the one at Nyiragongo, which is the largest to appear in recent times, are rare.
Image 32The Hubble Extreme Deep Field is an image of a small area of space in the constellation Fornax released by NASA on September 25, 2012. The successor to the Hubble Ultra-Deep Field, this image was compiled from 10 years of previous images with a total exposure time of two million seconds, or approximately 23 days.
Image 33Atlantic White-sided Dolphins, on a concrete-floored dock at the port of Hvalba, which is in the Faroe Islands, north of the United Kingdom. Whaling in the Faroe Islands has been practised since at least the 10th century. It is strongly regulated by Faroese authorities and is approved by the International Whaling Commission.
Image 34Lucky Diamond Rich (b. 1971) is a New Zealand-born performance artist and street performer who holds the Guinness World Record for most tattooed man, taking the title from Tom Leppard in 2006. He is recognized by Guinness as being covered in tattoos over 100% of his body, including the inside of his eyelids, ears, and mouth.
Image 35A swan created using modular origami, a paperfolding technique which uses two or more sheets of paper to create a larger and more complex structure than possible with single-piece origami techniques. Each individual sheet of paper is folded into a module, or unit, and then modules are assembled into an integrated flat shape or three-dimensional structure by inserting flaps into pockets created by the folding process. These insertions create tension or friction that holds the model together.
Image 36The 2004 Indian Ocean earthquake was a magnitude 9.15, undersea earthquake that occurred at 00:58:53 UTC on December 26 2004. The earthquake generated a tsunami that killed more than 150,000 people around the Indian Ocean, making it one of the deadliest disasters in modern history. This photograph shows the tsunami as it reached Ao Nang, Thailand.

Image 38Crowds surrounding the Reflecting Pool, during the August 28 1963 March on Washington for Jobs and Freedom. An estimated 200,000 to 500,000 people participated in the march, which featured Martin Luther King Jr.'s famous "I Have a Dream" speech. It was a major factor leading to the passage of the Civil Rights Act of 1964 and the 1965 Voting Rights Act. The march was also condemned by the Nation of Islam and Malcolm X, who termed it the "farce on Washington".
Image 39One of two monkey selfies taken by Celebes crested macaques using equipment belonging to the British nature photographer David Slater. In mid-2014, the images' hosting on Wikimedia Commons was at the centre of a dispute over whether copyright could be held on artworks made by non-human animals. Slater argued that, as he had "engineered" the shot, he held copyright, while Wikimedia considered the photographs public domain on the grounds that they were made by an animal rather than a person. In December 2014, the United States Copyright Office stated that works by a non-human are not subject to US copyright, a view reaffirmed by a US federal judge in 2016.
Image 40NGC 1300 is a barred spiral galaxy located roughly 69 million light-years away in the direction of the constellation Eridanus. In its core, the nucleus shows its own extraordinary and distinct "grand-design" spiral structure that is about 3,300 light-years long.
Image 41Glaucus atlanticus is a species of small, blue sea slug. This pelagic aeolid nudibranch floats upside down, using the surface tension of the water to stay up, and is carried along by the winds and ocean currents. The blue side of their body faces upwards, blending in with the blue of the water, while the grey side faces downwards, blending in with the silvery surface of the sea. G. atlanticus feeds on other pelagic creatures, including the Portuguese man o' war.

Image 43American astronaut Eugene Cernan (born March 14, 1934), shown here on the surface of the Moon during the Apollo 17 mission, the last time any human has set foot on it. In that final lunar landing mission, launched December 7, 1972, Cernan became "the last man on the moon" since he was the last to re-enter the Apollo Lunar Module during its third and final extra-vehicular activity. Prior to this, Cernan had also gone into space twice on the Gemini 9A and Apollo 10 missions.
Image 44aurora australis, as seen from the International Space Station. Aurorae are natural light displays in the sky caused by the collision of energetic charged particles with atoms in the high altitude thermosphere. The particles originate in the magnetosphere and solar wind and, on Earth, are directed by Earth's magnetic field into the atmosphere.
