Atropa bella-donna has a long history of use as a medicine, cosmetic, and poison. [14] [4] [15] Known originally under various folk names (such as "deadly nightshade" in English), the plant was named Atropa bella-donna by Carl Linnaeus (1707–1778) when he devised his classification system.
[4] [5] [6] It has contributed to most of the basic knowledge in fields such as human physiology and biochemistry, and has played significant roles in fields such as neuroscience and infectious disease. [7] [8] The results have included the near-eradication of polio and the development of organ transplantation, and have benefited both humans ...
There are many types of SCID mice used by researchers at present. Some examples include SCID-hu Thy/Liv mice, which are given human fetal thymus and liver cells, hu-SRC-SCID mice, which are implanted with human hematopoietic stem cells (HSC), and hu-PBL-SCID mice, in which human peripheral blood mononuclear cells have been injected.

The etymology of the word "morphology" is from the Ancient Greek μορφή (morphḗ), meaning "form", and λόγος (lógos), meaning "word, study, research". [2] [3]While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist ...
Toward a New Philosophy of Biology: Observations of an Evolutionist (published by Harvard University Press, Cambridge, Massachusetts, in 1988) is a book by Harvard evolutionary biologist Ernst Mayr. [ 1 ]
Developmental bioelectricity is a sub-discipline of biology, related to, but distinct from, neurophysiology and bioelectromagnetics.Developmental bioelectricity refers to the endogenous ion fluxes, transmembrane and transepithelial voltage gradients, and electric currents and fields produced and sustained in living cells and tissues.
That figure comes from an 1860 study, [297] but modern research shows that the average internal temperature is 36.4 °C (97.5 °F), with small fluctuations. [298] [299] [300] The cells in the human body are not outnumbered 10 to 1 by microorganisms. The 10 to 1 ratio was an estimate made in 1972; current estimates put the ratio at either 3 to 1 ...
An example of convergent evolution is carcinization, which is he convergent evolution of crustaceans to a crab-like body plan. Convergent evolution—the repeated evolution of similar traits in multiple lineages which all ancestrally lack the trait—is rife in nature, as illustrated by the examples below.
