Image 1A block is a defensive tactic in chess in response to an attack, consisting of interposing a piece between the opponent's attacking piece and the piece being attacked. This type of blocking will only work if the attacking piece is a type that can move linearly an indefinite number of squares such as a queen, rook, or bishop and there is at least one empty square in the line between the attacking and attacked piece. Blocking is not an option when the attacking piece is directly adjacent to the piece it is attacking, or when the attacking piece is a knight (because knights "jump over other pieces" and cannot be blocked). When an opponent's attack on a piece is blocked, the blocking piece is to some extent pinned, either relatively or absolutely, until a future move by either side allows it to be unpinned.
A check on a king by an opponent's queen, rook, or bishop can sometimes be blocked by moving a piece to a square in line in between the opponent's checking piece and the checked king. The blocking piece is then absolutely pinned to the king by the attacking piece.
Another type of interposing in chess can involve placing a piece between two opponent's pieces where one of those pieces is protecting the other, or they are both protecting each other. This chess tactic can be called interference. (Full article...)
Image 2A revenue model is a framework for generating financial income. There can be a variety of ways for revenue generation such as the production model, manufacturing model, as well as the construction model. A revenue model identifies which revenue source to pursue, what value to offer, how to price the value, and whopays for the value. It is a key component of a company's business model. A revenue model primarily identifies what product or service will be created and sold in order to generate revenues.
Without a clear and well-defined revenue model new businesses will be more likely to struggle. By having a clear revenue model, a business can focus on a target audience, fund development plans for a product or service, establish marketing plans, open a line of credit and raise capital.

Image 3Traditionally, meals have been prepared by women in a home kitchen (painting from the circle of Jean-Baptiste de Saive, 1563). A meal is an occasion that takes place at a certain time and includes consumption of food. The English names used for specific meals vary, depending on the speaker's culture, the time of day, or the size of the meal. A meal is different from a snack in that meals are generally larger, more varied, and more filling.
Though they can be eaten anywhere, meals usually take place in homes, restaurants, and cafeterias. Regular meals occur on a daily basis, typically several times a day. Special meals are normally held in conjunction with celebratory or momentous occasions such as birthdays, weddings, anniversaries, funerals, and holidays.
The type of food that is served or consumed at any given time depends on regional customs. Three main meals are typically eaten in the morning, early afternoon, and evening in most civilizations. Furthermore, the names of meals are often interchangeable by custom as well. Some serve dinner as the main meal at midday, with supper as the late afternoon/early evening meal, while others may call their midday meal lunch and their early evening meal supper or dinner. Except for breakfast, these names can vary from region to region or even from family to family. (Full article...)
Image 4A 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 5Emerging 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.

Image 6The branches of science, also referred to as sciences, scientificfields or scientific disciplines, are commonly divided into three major groups:
Scientific knowledge must be grounded in observable phenomena and must be capable of being verified by other researchers working under the same conditions.
Image 7Location of Asia Asian cuisine encompasses several significant regional cooking styles of Asia: Central Asian, East Asian, North Asian, South Asian, Southeast Asian, and West Asian. Cuisine is a distinctive way of cooking practices and customs, usually associated with a specific culture. Asia, as the largest and most populous continent, is home to many cultures, each with its own characteristic cuisine. Asian cuisine, also known as Eastern cuisine, is considered the "culture of food within a society" due to the beliefs, cooking methods, and the specific ingredients used throughout the entire process. Asian cuisines are also renowned for their spices. A key taste factor in Asian cuisine is “umami” flavor, a strong savoriness prominent in Asian cooking, which can be achieved through fermented food or meat extract.
Ingredients common to many cultures in East and Southeast Asia include rice, ginger, garlic, sesame seeds, chilis, dried onions, soy, and tofu. Stir frying, steaming, and deep frying are common cooking methods.
While rice is common to most Asian cuisines, different varieties are popular in the various regions. Glutinous rice is ingrained in the culture, religious tradition and national identity of Laos. Basmati rice is popular in the Indian subcontinent, jasmine rice is often found across Southeast Asia, while long-grain rice is popular in China and short-grain in Japan and Korea.
Curry is a common dish in South Asia, Southeast Asia, and East Asia. Curry dishes have their origins in the Indian subcontinent. Countries in Indochina typically use a coconut milk base in their curries; countries in Southwest Asia typically use a yogurt base. (Full article...)
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...)

Image 10The technological singularity—or simply the singularity—is a hypothetical future point in time at which technological growth becomes uncontrollable and irreversible, resulting in unforeseeable consequences for human civilization. According to the most popular version of the singularity hypothesis, I. J. Good's intelligence explosion model of 1965, an upgradable intelligent agent could eventually enter a positive feedback loop of self-improvement cycles, each successive; and more intelligent generation appearing more and more rapidly, causing a rapid increase ("explosion") in intelligence which would ultimately result in a powerful superintelligence, qualitatively far surpassing all human intelligence.
The Hungarian-American mathematician John von Neumann (1903-1957) became the first known person to use the concept of a "singularity" in the technological context.
Alan Turing, often regarded as the father of modern computer science, laid a crucial foundation for the contemporary discourse on the technological singularity. His pivotal 1950 paper, "Computing Machinery and Intelligence," introduces the idea of a machine's ability to exhibit intelligent behavior equivalent to or indistinguishable from that of a human.
Stanislaw Ulam reported in 1958 an earlier discussion with von Neumann "centered on the accelerating progress of technology and changes in human life, which gives the appearance of approaching some essential singularity in the history of the race beyond which human affairs, as we know them, could not continue". Subsequent authors have echoed this viewpoint. (Full article...)
Image 11Knowledge extraction is the creation of knowledge from structured (relational databases, XML) and unstructured (text, documents, images) sources. The resulting knowledge needs to be in a machine-readable and machine-interpretable format and must represent knowledge in a manner that facilitates inferencing. Although it is methodically similar to information extraction (NLP) and ETL (data warehouse), the main criterion is that the extraction result goes beyond the creation of structured information or the transformation into a relational schema. It requires either the reuse of existing formal knowledge (reusing identifiers or ontologies) or the generation of a schema based on the source data.
After the Portolá expedition of 1769–1770, Spanish missionaries began setting up 21 California missions on or near the coast of Alta (Upper) California, beginning with the Mission San Diego de Alcala near the location of the modern day city of San Diego, California. During the same period, Spanish military forces built several forts (presidios) and three small towns (pueblos). Two of the pueblos would eventually grow into the cities of Los Angeles and San Jose. After Mexico's Independence was won in 1821, California fell under the jurisdiction of the First Mexican Empire. Fearing the influence of the Roman Catholic church over their newly independent nation, the Mexican government closed all of the missions and nationalized the church's property. They left behind a "Californio" population of several thousand families, with a few small military garrisons. After the Mexican–American War of 1846–1848, The Mexican Republic was forced to relinquish any claim to California to the United States.
The California Gold Rush of 1848–1855 attracted hundreds of thousands of ambitious young people from around the world. Only a few struck it rich, and many returned home disappointed. Most appreciated the other economic opportunities in California, especially in agriculture, and brought their families to join them. California became the 31st U.S. state in the Compromise of 1850 and played a small role in the American Civil War. Chinese immigrants increasingly came under attack from nativists; they were forced out of industry and agriculture and into Chinatowns in the larger cities. As gold petered out, California increasingly became a highly productive agricultural society. The coming of the railroads in 1869 linked its rich economy with the rest of the nation, and attracted a steady stream of settlers. In the late 19th century, Southern California, especially Los Angeles, started to grow rapidly. (Full article...)
Natural science can be divided into two main branches: life science and physical science. Life science is alternatively known as biology, and physical science is subdivided into branches: physics, chemistry, earth science, and astronomy. These branches of natural science may be further divided into more specialized branches (also known as fields). As empirical sciences, natural sciences use tools from the formal sciences, such as mathematics and logic, converting information about nature into measurements that can be explained as clear statements of the "laws of nature".
Modern natural science succeeded more classical approaches to natural philosophy. Galileo, Kepler, Descartes, Bacon, and Newton debated the benefits of using approaches which were more mathematical and more experimental in a methodical way. Still, philosophical perspectives, conjectures, and presuppositions, often overlooked, remain necessary in natural science. Systematic data collection, including discovery science, succeeded natural history, which emerged in the 16th century by describing and classifying plants, animals, minerals, and so on. Today, "natural history" suggests observational descriptions aimed at popular audiences. (Full article...)
Image 14Etruscan: 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 15Human 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.
Early discussions of overpopulation in English were spurred by the work of Thomas Malthus. Discussions of overpopulation follow a similar line of inquiry as Malthusianism and its Malthusian catastrophe, a hypothetical event where population exceeds agricultural capacity, causing famine or war over resources, resulting in poverty and depopulation. More recent discussion of overpopulation was popularized by Paul Ehrlich in his 1968 book The Population Bomb and subsequent writings. Ehrlich described overpopulation as a function of overconsumption, arguing that overpopulation should be defined by a population being unable to sustain itself without depleting non-renewable resources.
Image 17A 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 18Two 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 20An 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 21Web scraping, web harvesting, or web data extraction is data scraping used for extracting data from websites. Web scraping software may directly access the World Wide Web using the Hypertext Transfer Protocol or a web browser. While web scraping can be done manually by a software user, the term typically refers to automated processes implemented using a bot or web crawler. It is a form of copying in which specific data is gathered and copied from the web, typically into a central local database or spreadsheet, for later retrieval or analysis.
Scraping a web page involves fetching it and then extracting data from it. Fetching is the downloading of a page (which a browser does when a user views a page). Therefore, web crawling is a main component of web scraping, to fetch pages for later processing. Having fetched, extraction can take place. The content of a page may be parsed, searched and reformatted, and its data copied into a spreadsheet or loaded into a database. Web scrapers typically take something out of a page, to make use of it for another purpose somewhere else. An example would be finding and copying names and telephone numbers, companies and their URLs, or e-mail addresses to a list (contact scraping).
Web pages are built using text-based mark-up languages (HTML and XHTML), and frequently contain a wealth of useful data in text form. However, most web pages are designed for human end-users and not for ease of automated use. As a result, specialized tools and software have been developed to facilitate the scraping of web pages. Web scraping applications include market research, price comparison, content monitoring, and more. Businesses rely on web scraping services to efficiently gather and utilize this data.

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...)
Image 24A 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 25 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 4HPE Frontier at the Oak Ridge Leadership Computing Facility is the world's first exascale supercomputer. Exascale computing refers to computing systems capable of calculating at least 10 IEEE 754 Double Precision (64-bit) operations (multiplications and/or additions) per second (exaFLOPS)"; it is a measure of supercomputer performance.
Exascale computing is a significant achievement in computer engineering: primarily, it allows improved scientific applications and better prediction accuracy in domains such as weather forecasting, climate modeling and personalised medicine. Exascale also reaches the estimated processing power of the human brain at the neural level, a target of the now defunct Human Brain Project. There has been a race to be the first country to build an exascale computer, typically ranked in the TOP500 list. (Full article...)
Image 5In condensed matter physics, a time crystal is a quantum system of particles whose lowest-energy state is one in which the particles are in repetitive motion. The system cannot lose energy to the environment and come to rest because it is already in its quantum ground state. Time crystals were first proposed theoretically by Frank Wilczek in 2012 as a time-based analogue to common crystals – whereas the atoms in crystals are arranged periodically in space, the atoms in a time crystal are arranged periodically in both space and time. Several different groups have demonstrated matter with stable periodic evolution in systems that are periodically driven. In terms of practical use, time crystals may one day be used as quantum computer memory.
The existence of crystals in nature is a manifestation of spontaneous symmetry breaking, which occurs when the lowest-energy state of a system is less symmetrical than the equations governing the system. In the crystal ground state, the continuous translational symmetry in space is broken and replaced by the lower discrete symmetry of the periodic crystal. As the laws of physics are symmetrical under continuous translations in time as well as space, the question arose in 2012 as to whether it is possible to break symmetry temporally, and thus create a "time crystal" that is resistant to entropy.

Image 6Atomic scale moiré pattern created by overlapping two skewed sheets of graphene, a hexagonal lattice composed of carbon atoms. Twistronics (from twist and electronics) is the study of how the angle (the twist) between layers of two-dimensional materials can change their electrical properties. Materials such as bilayer graphene have been shown to have vastly different electronic behavior, ranging from non-conductive to superconductive, that depends sensitively on the angle between the layers. The term was first introduced by the research group of Efthimios Kaxiras at Harvard University in their theoretical treatment of graphene superlattices.
A mesh refers to rich interconnection among devices or nodes. Wireless mesh networks often consist of mesh clients, mesh routers and gateways. Mobility of nodes is less frequent. If nodes constantly or frequently move, the mesh spends more time updating routes than delivering data. In a wireless mesh network, topology tends to be more static, so that routes computation can converge and delivery of data to their destinations can occur. Hence, this is a low-mobility centralized form of wireless ad hoc network. Also, because it sometimes relies on static nodes to act as gateways, it is not a truly all-wireless ad hoc network.

Most USRPs connect to a host computer through a high-speed link, which the host-based software uses to control the USRP hardware and transmit/receive data. Some USRP models also integrate the general functionality of a host computer with an embedded processor that allows the USRP device to operate in a stand-alone fashion. (Full article...)
Image 9The general definition of a qubit as the quantum state of a two-level quantum system. In quantum computing, a qubit (/ˈkjuːbɪt/) or quantum bit is a basic unit of quantum information—the quantum version of the classic binary bit physically realized with a two-state device. A qubit is a two-state (or two-level) quantum-mechanical system, one of the simplest quantum systems displaying the peculiarity of quantum mechanics. Examples include the spin of the electron in which the two levels can be taken as spin up and spin down; or the polarization of a single photon in which the two spin states (left-handed and the right-handed circular polarization) can also be measured as horizontal and vertical linear polarization. In a classical system, a bit would have to be in one state or the other. However, quantum mechanics allows the qubit to be in a coherent superposition of multiple states simultaneously, a property that is fundamental to quantum mechanics and quantum computing.

Image 10Thyristor RAM (T-RAM) is a type of random-access memory dating from 2009 invented and developed by T-RAM Semiconductor, which departs from the usual designs of memory cells, combining the strengths of the DRAM and SRAM: high density and high speed. This technology, which exploits the electrical property known as negative differential resistance and is called thin capacitively-coupled thyristor, is used to create memory cells capable of very high packing densities. Due to this, the memory is highly scalable, and already has a storage density that is several times higher than found in conventional 6T SRAM. It was expected that the next generation of T-RAM memory will have the same density as DRAM.
This technology exploits the electrical property known as negative differential resistor and is characterized by the way in which its memory cells are built, combining DRAM efficiency in terms of space with that of SRAM in terms of speed. Very similar to the current 6T-SRAM, or SRAM memories with 6 cell transistors, is substantially different because the SRAM latch CMOS, consisting of 4 of the 6 transistors of each cell, is replaced by a bipolar latch PNP -NPN of a single Thyristor. The result is to significantly reduce the area occupied by each cell, thus obtaining a highly scalable memory that has already reached storage density several times higher than the current SRAM.

A head-up display, or heads-up display, also known as a HUD (/hʌd/) or head-up guidance system (HGS), is any transparent display that presents data without requiring users to look away from their usual viewpoints. The origin of the name stems from a pilot being able to view information with the head positioned "up" and looking forward, instead of angled down looking at lower instruments. A HUD also has the advantage that the pilot's eyes do not need to refocus to view the outside after looking at the optically nearer instruments.
Although they were initially developed for military aviation, HUDs are now used in commercial aircraft, automobiles, and other (mostly professional) applications. (Full article...)
Image 12Hand transplantation, or simply a hand transplant, is a surgical procedure to transplant a hand from one human to another. The donor hand, usually from a brain-dead donor, is transplanted to a recipient amputee. Most hand transplants to date have been performed on below-elbow amputees, although above-elbow transplants are gaining popularity. Hand transplants were the first of a new category of transplants where multiple organs are transplanted as a single functional unit, now termed vascularized composite allotransplantation (VCA).
The operation is quite extensive and typically lasts from 8 to 12 hours. In comparison, a typical heart transplant operation lasts 6 to 8 hours. Surgeons usually connect the bones first, followed by tendons, arteries, nerves, veins, and skin. (Full article...)
Image 14The plasma window (not to be confused with a plasma shield) is a technology that fills a volume of space with plasma confined by a magnetic field. With current technology, this volume is quite small and the plasma is generated as a flat plane inside a cylindrical space.
Plasma is any gas whose atoms or molecules have been ionized, and is a separate phase of matter. This is most commonly achieved by heating the gas to extremely high temperatures, although other methods exist. Plasma becomes increasingly viscous at higher temperatures, to the point where other matter has trouble passing through. (Full article...)
Digital currencies exhibit properties similar to traditional currencies, but generally do not have a classical physical form of fiat currency historically that can be held in the hand, like currencies with printed banknotes or minted coins. However, they do have a physical form in an unclassical sense coming from the computer to computer and computer to human interactions and the information and processing power of the servers that store and keep track of money. This unclassical physical form allows nearly instantaneous transactions over the internet and vastly lowers the cost associated with distributing notes and coins: for example, of the types of money in the UK economy, 3% are notes and coins, and 79% as electronic money (in the form of bank deposits). Usually not issued by a governmental body, virtual currencies are not considered a legal tender and they enable ownership transfer across governmental borders. (Full article...)

In the case of organ printing, the material being used by the printer is a biocompatible plastic. The biocompatible plastic forms a scaffold that acts as the skeleton for the organ that is being printed. As the plastic is being laid down, it is also seeded with human cells from the patient's organ that is being printed for. After printing, the organ is transferred to an incubation chamber to give the cells time to grow. After a sufficient amount of time, the organ is implanted into the patient. To many researchers the ultimate goal of organ printing is to create organs that can be fully integrated into the human body. Successful organ printing has the potential to impact several industries, notably artificial organsorgan transplants, pharmaceutical research, and the training of physicians and surgeons.

Image 18Ekranoplan A-90 Orlyonok A ground-effect vehicle (GEV), also called a wing-in-ground-effect (WIGE or WIG), ground-effect craft/machine (GEM), wingship, flarecraft, surface effect vehicle or ekranoplan (Russian: экранопла́н – "screenglider"), is a vehicle that is able to move over the surface by gaining support from the reactions of the air against the surface of the earth or water. Typically, it is designed to glide over a level surface (usually over the sea) by making use of ground effect, the aerodynamic interaction between the moving wing and the surface below. Some models can operate over any flat area such as frozen lakes or flat plains similar to a hovercraft. The term Ground-Effect Vehicle originally referred to any craft utilizing ground effect, including what is known later as hovercraft, in descriptions of patents during the 1950s. However, this term is nowadays regarded as distinct from air-cushion vehicles or hovercraft. The definition of GEVs does not include racecars utilizing ground-effect for increasing downforce.

Image 19Using the VirtuSphere simulator VirtuSphere is a sphericalvirtual reality device. It consists of a 10-foot hollow sphere, which is placed on a special platform that allows the sphere to rotate freely in any direction according to the user’s steps. It works with computer based simulations and virtual worlds, and rotates as the user walks, allowing for an unlimited plane upon which the user can walk. A wireless head-mounted display with gyroscopes is used to both track the user's head movement as well as display the environment of the virtual world. VirtuSphere can serve many purposes, including exercise, video gaming, military training, and virtual museum tours.
The VirtuSphere is a creation of Ray and Nurulla Latypov, whose company, VirtuSphere Inc, is based in Binghamton, New York. (Full article...)

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 22A volumetric display device is a display device that forms a visual representation of an object in three physical dimensions, as opposed to the planar image of traditional screens that simulate depth through a number of different visual effects. One definition offered by pioneers in the field is that volumetric displays create 3D imagery via the emission, scattering, or relaying of illumination from well-defined regions in (x,y,z) space.
A true volumetric display produces in the observer a visual experience of a material object in three-dimensional space, even though no such object is present. The perceived object displays characteristics similar to an actual material object by allowing the observer to view it from any direction, to focus a camera on a specific detail, and to see perspective – meaning that the parts of the image closer to the viewer appear larger than those further away.

Image 24 An expendable launch system (or expendable launch vehicle/ELV) is a launch vehicle that can be launched only once, after which its components are destroyed during reentry or impact with Earth, or discarded in space. ELVs typically consist of several rocket stages that are discarded sequentially as their fuel is exhausted and the vehicle gains altitude and speed. As of 2024, fewer and fewer satellites and human spacecraft are launched on ELVs in favor of reusable launch vehicles. However, there are many instances where a ELV may still have a compelling use case over a reusable vehicle. ELVs are simpler in design than reusable launch systems and therefore may have a lower production cost. Furthermore, an ELV can use its entire fuel supply to accelerate its payload, offering greater payloads. ELVs are proven technology in widespread use for many decades. (Full article...)
"Aeronautical engineering" was the original term for the field. As flight technology advanced to include vehicles operating in outer space, the broader term "aerospace engineering" has come into use. Aerospace engineering, particularly the astronautics branch, is often colloquially referred to as "rocket science". (Full article...)
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...)
Image 2A typical suburban development in the United States, located in Chandler, Arizona Urban sprawl (also known as suburban sprawl or urban encroachment) is defined as "the spreading of urban developments (such as houses and shopping centers) on undeveloped land near a city". Urban sprawl has been described as the unrestricted growth in many urban areas of housing, commercial development, and roads over large expanses of land, with little concern for very dense urban planning. Sometimes the urban areas described as the most "sprawling" are the most densely populated. In addition to describing a special form of urbanization, the term also relates to the social and environmental consequences associated with this development. In modern times some suburban areas described as "sprawl" have less detached housing and higher density than the nearby core city. Medieval suburbs suffered from the loss of protection of city walls, before the advent of industrial warfare. Modern disadvantages and costs include increased travel time, transport costs, pollution, and destruction of the countryside. The revenue for building and maintaining urban infrastructure in these areas are gained mostly through property and sales taxes. Most jobs in the US are now located in suburbs generating much of the revenue, although a lack of growth will require higher tax rates.
In Europe, the term peri-urbanisation is often used to denote similar dynamics and phenomena, but the term urban sprawl is currently being used by the European Environment Agency. There is widespread disagreement about what constitutes sprawl and how to quantify it. For example, some commentators measure sprawl by residential density, using the average number of residential units per acre in a given area. Others associate it with decentralization (spread of population without a well-defined centre), discontinuity (leapfrogging development, as defined below), segregation of uses, and so forth.
The term urban sprawl is highly politicized and almost always has negative connotations. It is criticized for causing environmental degradation, intensifying segregation, and undermining the vitality of existing urban areas, and is attacked on aesthetic grounds. The pejorative meaning of the term means that few openly support urban sprawl as such. The term has become a rallying cry for managing urban growth. (Full article...)

Image 4Early 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.
Image 6Global 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 8Summary 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...)

Image 10The 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...)
Image 11The dodo became extinct during the mid-to-late 17th century due to habitat destruction, overhunting, and predation by introduced mammals. It is an often-cited example of a human-driven extinction.
The Holocene extinction, also referred to as the Anthropocene extinction, is an ongoing extinction event caused by human activities during the Holocene epoch. This extinction event spans numerous families of plants and animals, including mammals, birds, reptiles, amphibians, fish, and invertebrates, impacting both terrestrial and marine species. Widespread degradation of biodiversity hotspots such as coral reefs and rainforests has exacerbated the crisis. Many of these extinctions are undocumented, as the species are often undiscovered before their extinctions.
Current extinction rates are estimated at 100 to 1,000 times higher than natural background extinction rates and are accelerating. Over the past 100–200 years, biodiversity loss has reached such alarming levels that some conservation biologists now believe human activities have triggered a mass extinction, or are on the cusp of doing so. As such, after the "Big Five" mass extinctions, the Holocene extinction event has been referred to as the sixth mass extinction. However, given the recent recognition of the Capitanian mass extinction, the term seventh mass extinction has also been proposed.
The Holocene extinction was preceded by the extinction of most large (megafaunal) animals during the Late Pleistocene, a decline attributed in part to human hunting. The prevailing theory is that human overhunting, coinciding with existing stress conditions, likely contributed to this decline. Examples from regions such as New Zealand, Madagascar, and Hawaii have shown how human colonization and habitat destruction have led to significant biodiversity losses. While debates persist about the exact role of human predation and habitat alteration, certain extinctions have been directly linked to these activities. Additionally, climate shifts at the end of the Pleistocene likely compounded these effects. (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.

Unemployment can have many sources, such as the following: (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.
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 17Ocean acidification means that the average seawaterpH value is dropping over time.
Ocean acidification is the ongoing decrease in the pH of the Earth's ocean. Between 1950 and 2020, the average pH of the ocean surface fell from approximately 8.15 to 8.05. Carbon dioxide emissions from human activities are the primary cause of ocean acidification, with atmospheric carbon dioxide (CO2) levels exceeding 422 ppm (as of 2024). CO2 from the atmosphere is absorbed by the oceans. This chemical reaction produces carbonic acid (H2CO3) which dissociates into a bicarbonate ion (HCO−3) and a hydrogen ion (H). The presence of free hydrogen ions (H) lowers the pH of the ocean, increasing acidity (this does not mean that seawater is acidic yet; it is still alkaline, with a pH higher than 8). Marine calcifying organisms, such as mollusks and corals, are especially vulnerable because they rely on calcium carbonate to build shells and skeletons.
A change in pH by 0.1 represents a 26% increase in hydrogen ion concentration in the world's oceans (the pH scale is logarithmic, so a change of one in pH units is equivalent to a tenfold change in hydrogen ion concentration). Sea-surface pH and carbonate saturation states vary depending on ocean depth and location. Colder and higher latitude waters are capable of absorbing more CO2. This can cause acidity to rise, lowering the pH and carbonate saturation levels in these areas. There are several other factors that influence the atmosphere-ocean CO2 exchange, and thus local ocean acidification. These include ocean currents and upwelling zones, proximity to large continental rivers, sea ice coverage, and atmospheric exchange with nitrogen and sulfur from fossil fuel burning and agriculture.
A lower ocean pH has a range of potentially harmful effects for marine organisms. Scientists have observed for example reduced calcification, lowered immune responses, and reduced energy for basic functions such as reproduction. Ocean acidification can impact marine ecosystems that provide food and livelihoods for many people. About one billion people are wholly or partially dependent on the fishing, tourism, and coastal management services provided by coral reefs. Ongoing acidification of the oceans may therefore threaten food chains linked with the oceans. (Full article...)
Image 18Pollution is the introduction of contaminants into the natural environment that cause harm. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.
Image 19Human 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.
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 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.
Image 22Women 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."
Image 23Map of the world's biodiversity hot spots, all of which are heavily threatened by habitat loss and degradation
Habitat destruction (also termed habitat loss and habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide.
Environmental disasters show how the impact of humans' alteration of the land has led to widespread and/or long-lasting consequences. These disasters have included deaths of wildlife, humans and plants, or severe disruption of human life or health, possibly requiring migration. Some environmental disasters are the trigger source of more expansive environmental conflicts, where effected groups try to socially confront the actors responsible for the disaster.

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 2Devastation 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 10An 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.

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 17A 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 19An 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 21The sperm whale is the largest toothed animal on Earth. The species was hunted extensively by humans throughout history, until protected by a worldwide moratorium on whaling starting in 1985–86.
Image 22A 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 23A 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 25Crash landing of an F6F Hellcat into the port side 20mm gun gallery of the USS Enterprise, November 10, 1943. Lieutenant Walter L. Chewning, Jr., USNR, the Catapult Officer, is climbing up the plane's side to assist the pilot from the burning aircraft. The pilot, Ensign Byron M. Johnson, escaped without significant injury. Note the plane's ruptured belly fuel tank.
Image 27Glaucus 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 28San 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 29The 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 30The 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 32A 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 35One 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 36Sandboarding 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 38The 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 39The 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 42The 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 45A 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.

A valuable service
I think you need recognition for doing the job of ten other editors, and doing it out of altruism and genuine belief in Misplaced Pages. Not many editors here have the same good attitude and provide the same service as you - I don't have any specific point to put across, but I thought you should just be prodded and reminded that you do a lot of good around here, in the hope you'll keep it up. Kudos! Seegoon (talk) 17:43, 25 January 2008 (UTC)
Just a note, I've made a minor update to your contributions. To reiterate my edit summary, you put in a tonne of effort there, and you deserve to be credited for it :) Feel free to revert, nonetheless. Regards, AGK (contact) 16:44, 29 February 2008 (UTC)

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.

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.

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!

Image 1A block is a defensive tactic in chess in response to an attack, consisting of interposing a piece between the opponent's attacking piece and the piece being attacked. This type of blocking will only work if the attacking piece is a type that can move linearly an indefinite number of squares such as a queen, rook, or bishop and there is at least one empty square in the line between the attacking and attacked piece. Blocking is not an option when the attacking piece is directly adjacent to the piece it is attacking, or when the attacking piece is a knight (because knights "jump over other pieces" and cannot be blocked). When an opponent's attack on a piece is blocked, the blocking piece is to some extent pinned, either relatively or absolutely, until a future move by either side allows it to be unpinned.

Image 1NGC 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 2Devastation 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 3The 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 4The "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 5The mushroom cloud caused by the detonation of the "Fat Man" bomb during the atomic bombing of Nagasaki, Japan in 1945, rising approximately 18 kilometres (11 mi) above the hypocenter.
Image 6Atlantic 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 7The 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 9The 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 10An 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 11Imagine waking up to this. Which makes me wonder whatever happened to the guy who took this photo.

Image 13Lucky 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 14Crowds 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 15The 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 17A 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 18aurora 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.
Image 19An 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 21The sperm whale is the largest toothed animal on Earth. The species was hunted extensively by humans throughout history, until protected by a worldwide moratorium on whaling starting in 1985–86.
Image 22A 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 23A 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 25Crash landing of an F6F Hellcat into the port side 20mm gun gallery of the USS Enterprise, November 10, 1943. Lieutenant Walter L. Chewning, Jr., USNR, the Catapult Officer, is climbing up the plane's side to assist the pilot from the burning aircraft. The pilot, Ensign Byron M. Johnson, escaped without significant injury. Note the plane's ruptured belly fuel tank.

Image 27Glaucus 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 28San 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 29The 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 30The 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 31Tracy Caldwell Dyson in the Cupola module of the International Space Station, observing the Earth below during Expedition 24. Caldwell Dyson is an American chemist and astronaut. She was selected by NASA in 1998 and made her first spaceflight in August 2007 on the STS-118 mission aboard Space Shuttle Endeavour.
Image 32A 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 33Burj 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 34Astronaut 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 35One 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 36Sandboarding 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 37United States Navy personnel engage in Special Patrol Insertion/Extraction (SPIE) training between a Sikorsky SH-60 Seahawk helicopter and the USS Dwight D. Eisenhower (CVN-69). 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 38The 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 39The 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 40The 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 41American 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 42The 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 45A 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.
