Unusually elevated core body temperature resulting from fever or prolonged exposure to a hot environment. This can be a life threatening condition. See hypothermia.
Industry:Anthropology
A relative dating method based on the fact that bones buried in the ground progressively lose nitrogen and gain fluorine and other trace elements. The rate at which these changes occur depends on the local environment. If two bones from the same site have markedly different amounts of nitrogen and fluorine, it is a strong indication that they did not come from the same time period. The bone with the least amount of nitrogen and the greatest amount of fluorine is most likely the oldest.
Industry:Anthropology
A long period of time during which earth's climate cools, causing glaciers to expand out from the poles and mountains covering vast areas. The glacials of the Pleistocene Epoch mostly occurred in the northern hemisphere. See interglacial.

A bone disorder in which there is a progressive reduction in bone density resulting in brittleness and increased porosity. People with osteoporosis are at a high risk for bone fractures. This disorder is most commonly found among post-menopausal women. However, it also occurs at a high frequency among men who have low testosterone levels (e. G. , men with Klinefelter syndrome).
Industry:Anthropology
A dark colored organic pigment produced in the skin. There are two forms of melanin----pheomelanin, which is red to yellow in color, and eumelanin, which is dark brown to black. People with light complexioned skin mostly produce pheomelanin, while those with dark colored skin mostly produce eumelanin. High concentrations of melanin near the surface of the skin result in a darker complexion. Suntanned skin also has higher concentrations of melanin.

Industry:Anthropology
A category of extremely small microscopic parasites of plants, animals, and bacteria. Viruses are not cells but rather RNA or DNA molecules surrounded by a protein coating. Since viruses cannot reproduce without a host cell, they are not strictly speaking living organisms. There are many kinds of viruses.
Industry:Anthropology
A kind of positively charged subnuclear particle (consisting of 2 protons and 2 neutrons) given off by some isotopes when they decay or fission.
Industry:Anthropology
A protein that has the ability to cause the cells that it invades to repeatedly duplicate it. Prions are responsible for causing Mad Cow Disease. Apparently, prions are not effectively attacked by their host's immune system nor can they be killed with existing antibiotics, extreme heat, cold, or other normally lethal conditions. The word prion comes from "proteinaceous infectious particle. "
