| Antarctic circumpolar current The Antarctic Circumpolar Current (ACC) is an ocean current that flows from west to east around Antarctica. An alternate name for the ACC is the West Wind Drift. The ACC is the dominant circulation feature of the Southern Ocean and, at approximately 125 Sverdrups, the largest ocean current . It keeps warm ocean waters away from Antarctica, enabling that continent to maintain its huge ice sheet. Antarctic_circumpolar_current | |
| Alcoholism Alcoholism is a term with multiple and sometimes conflicting definitions.In common and historic usage, alcoholism refers to any condition that results in the continued consumption of alcoholic beverages despite health problems and negative social consequences. Alcoholism | |

| Beer Beer is the world's oldest and most widely consumed alcoholic beverage and the third most popular drink overall after water and tea. It is produced by the brewing and fermentation of starches, mainly derived from cereal grains—the most common of which is malted barley, although wheat, maize (corn), and rice are widely used. Most beer is flavoured with hops, which add bitterness and act as a natural preservative, though other flavourings such as herbs or fruit may occasionally be included. Beer | |
| Black hole In general relativity, a black hole is a region of space in which the gravitational field is so powerful that nothing, including light, can escape its pull. The black hole has a one-way surface, called an event horizon, into which objects can fall, but out of which nothing can come. It is called "black" because it absorbs all the light that hits it, reflecting nothing, just like a perfect blackbody in thermodynamics. Quantum analysis of black holes shows them to possess a temperature and Hawking radiation. Black_hole | |
| Carbon nanotube Carbon nanotubes (CNTs) are allotropes of carbon with a cylindrical nanostructure. Nanotubes have been constructed with length-to-diameter ratio of up to 28,000,000carbon molecules have novel properties that make them potent Carbon_nanotube | |
| Chandrasekhar limit Chandrasekhar limit limits the mass of bodies made from electron-degenerate matter, a dense form of matter which consists of nuclei immersed in a gas of electrons. The limit is the maximum nonrotating mass which can be supported against gravitational collapse by electron degeneracy pressure. Chandrasekhar_limit | |

| Chocolate Chocolate (pronounced or /-ˈələt/) comprises a number of raw and processed foods that are produced from the seed of the tropical cacao tree. Native to lowland, tropical South America, cacao has been cultivated for at least three millennia in Central America and Mexico, with its earliest documented use around 1100 BC. Chocolate | |
| Cold fusion Cold fusion refers to a postulated nuclear fusion process of unknown mechanism offered to explain a group of disputed experimental results first reported by electrochemists Martin Fleischmann and Stanley Pons. Cold fusion research sometimes is referred to as low energy nuclear reaction (LENR) studies or condensed matter nuclear science.Cold fusion, under this definition, was first announced on March 23, 1989 when Fleischmann and Pons reported producing nuclear fusion in a tabletop experiment involving electrolysis of heavy water on a palladium (Pd) electrode.

| Cactus A cactus (pluralcacti or cactuses) is any member of the plant family Cactaceae, native to the Americas. They are often used as ornamental plants, but some are also crop plants. Cacti are grown for protection of property from wild animals, as well as many other uses. Cacti are part of the plant order Caryophyllales, which also includes members like beets, baby's breath, spinach, amaranth, tumbleweeds, carnations, rhubarb, buckwheat, plumbago, bougainvillea, chickweed and knotgrass.

| Goeldi's Monkey Goeldi's Marmoset or Goeldi's Monkey (Callimico goeldii) is a small, South American New World monkey that lives in the upper Amazon Basin region of Bolivia, Brazil, Colombia, Ecuador, and Peru. It is the only species classified in the genus Callimico, and the monkeys are sometimes referred to as "callimicos". Goeldi's Marmosets are blackish or blackish-brown in color. Their bodies are about 8–9 inches (20–23 Goeldi's_Monkey | |
| Homeostasis Homeostasis (from Greek:hómos, "similar"; and ιστημι, histēmi, "standing still"; defined by Walter Bradford Cannon in 1929 + 1932) is the property of a system, either open or closed, that regulates its internal environment and tends to maintain a stable, constant condition. Homeostasis | |
| Hematite Hematite, also spelled as hæmatite, is the mineral form of Iron(III) oxide (Fe2O3), one of several iron oxides. Hematite crystallizes in the rhombohedral system, and it has the same crystal structure as ilmenite and as corundum. Hematite and ilmenite form a complete solid solution at temperatures above 950°C. Hematite | |
| Insulin Insulin is a hormone that has extensive effects on metabolism and other body functions, such as vascular compliance. Insulin causes cells in the liver, muscle, and fat tissue to take up glucose from the blood, storing it as glycogen in the liver and muscle, and stopping use of fat as an energy source. Insulin | |
| Ivory-billed Woodpecker The Ivory-billed Woodpecker (Campephilus principalis) is, or was, a very large member of the family Picidae. It was considered extinct for many years until a series of possible sightings beginning in 1999. It is currently officially listed as a critically endangered species by the International Union for Conservation of Nature (IUCN) after being upgraded from extinct in 2000.

| Intersexuality Intersexuality in humans refers to intermediate or atypical combinations of physical features that usually distinguish male from female. An intersex organism may have biological characteristics of both the male and female sexes. Intersexuality is the term adopted by medicine during the 20th century applied to human beings whose biological sex cannot be classified as either male or female. Intersexuality | |

| Lactase Lactase (LCT), a part of the β-galactosidase family of enzymes, is a glycoside hydrolase involved in the hydrolysis of the disaccharide lactose into constituent galactose and glucose monomers. In humans, lactase is present predominantly along the brush border membrane of the differentiated enterocytes lining the villi of the small intestine.Lactase is essential for digestive hydrolysis of lactose in milk. Deficiency of the enzyme causes lactose intolerance. Lactase | |
| Flowering plant The flowering plants or angiosperms (Angiospermae or Magnoliophyta) are the most widespread group of land plants. The flowering plants and the gymnosperms are the only extant groups of seed plants. The flowering plants are distinguished from other seed plants by a series of apomorphies, or derived characteristics. Flowering_plant | |
| Molybdenum Molybdenum (, from the Greek word for the metal "lead"), is a Group 6 chemical element with the symbol Mo and atomic number 42. The free element, which is a silvery metal, has the sixth-highest melting point of any element. It readily forms hard, stable carbides, and for this reason it is often used in high-strength steel alloys. Molybdenum | |

| Monoamine oxidase Monoamine oxidases (singular abbreviation MAO) () are enzymes that catalyze the oxidation of monoamines. They are found bound to the outer membrane of mitochondria in most cell types in the body. The enzyme was discovered by Mary Hare in the liver, and received the name of tyramine oxidase. They belong to protein family of flavin-containing amine oxidoreductases. Monoamine_oxidase | |
| Native Americans in the United States Native Americans in the United States are the indigenous peoples from the regions of North America now encompassed by the continental United States, including parts of Alaska and the island state of Hawaii. They comprise a large number of distinct tribes, states, and ethnic groups, many of which survive as intact political communities. Native_Americans_in_the_United_States | |
| Neptunium Neptunium () is a chemical element with the symbol Np and atomic number 93. A radioactive metallic element, neptunium is the first transuranic element and belongs to the actinide series. Its most stable isotope, 237Np, is a by-product of nuclear reactors and plutonium production and it can be used as a component in neutron detection equipment. Neptunium is also found in trace amounts in uranium ores due to transmutation reactions. Neptunium | |
| Orgasm An orgasm (sexual climax) is the peak conclusion of the plateau phase of the sexual response cycle, characterized by an intense sensation of pleasure. Experienced by both males and females, orgasm is controlled by the involuntary, or autonomic, limbic nervous system, and is accompanied by quick cycles of muscle contraction in the lower pelvic muscles, which surround the primary sexual organs and the anus. Orgasm | |

| Peer review Peer review (also known as refereeing) is the process of subjecting an author's scholarly work, research, or ideas to the scrutiny of others who are experts in the same field. Peer review requires a community of experts in a given (and often narrowly defined) field, who are qualified and able to perform impartial review. Peer_review | |
| Race and intelligence Race and intelligence have in some cases been claimed to be correlated. Contemporary debate on this issue focuses on the nature, causes, and rectifications of ethnic differences in intelligence test scores. The question of the relative roles of nature and nurture in correlation does not prove causation. No gene has been shown to be linked to intelligence, "so attempts to provide a compelling genetic link of race to intelligence are not feasible at this time". Race_and_intelligence | |

| Whale Whales are marine mammals of order Cetacea which are neither dolphinsDelphinidae or Platanistoidae—porpoises. They include the blue whale, the largest living animal. Orcas, colloquially referred to as "killer whales", and pilot whales have whale in their name but for the purpose of biological classification they are actually dolphins. Whale | |
| Yellowstone National Park Yellowstone National Park, established by the U.S. Congress as a national park on March 1, 1872, is located primarily in the U.S. state of Wyoming, though it also extends into Montana and Idaho. The park was the first of its kind, and is known for its wildlife and its many geothermal features, especially Old Faithful Geyser, one of the most popular features in the park.

| Little Ice Age Little Ice Age (LIA) was a period of cooling occurring after a warmer North Atlantic era known as the Medieval Warm Period. While not a true ice age, the term was introduced into scientific literature by François E. Matthes in 1939. Climatologists and historians working with local records no longer expect to agree on either the start or end dates of this period, which varied according to local conditions. Little_Ice_Age | |
| Kidney stone Kidney stones (called renal calculi in medical terminology, from Latin ren, renes, "kidney" and calculi, "pebbles"), are solid concretions (crystal aggregations) formed in the kidneys from dissolved urinary minerals. The terms nephrolithiasis and urolithiasis refer to the condition of having calculi in the kidneys and urinary tract, respectively. Kidney_stone |
