Immortalised cell lines are widely used as a simple model for more complex biological systems – for example, for the analysis of the biochemistry and cell biology of mammalian (including human) cells. [2] The main advantage of using an immortal cell line for research is its immortality; the cells can be grown indefinitely in culture.
For example, John le Carré's 2001 The Constant Gardener, and its film adaptation, tells the tale of the testing of anti-tuberculosis drugs on unwitting subjects in Africa. [20] In the 1915 novel Anne of the Island, the third in the Anne of Green Gables series, Ruby Gillis, one of Anne's childhood friends, dies of "the galloping consumption". [21]
Thomas began writing a monthly essay “Notes of a Biology Watcher” in the New England Journal of Medicine in 1971 while he was at Yale. In 1973 he became the president of the Sloan-Kettering Institute in New York. Lewis Thomas published multiple books throughout his career, the first being The Lives of a Cell: Notes of a Biology Watcher.
Homochirality is an obvious characteristic of life on Earth, yet extraterrestrial samples contain largely racemic compounds. [7] It is not known whether homochirality existed before life, whether the building blocks of life must have this particular chirality, or whether life must be homochiral at all.
The evolution of biological complexity is one important outcome of the process of evolution. [1] Evolution has produced some remarkably complex organisms – although the actual level of complexity is very hard to define or measure accurately in biology, with properties such as gene content, the number of cell types or morphology all proposed as possible metrics.
The two-part disaster series Flood and Ark (followed by three additional stories, "Earth III," "Earth II," and "Earth I") which also fits into this category, where catastrophic events unfold in the near future and humanity must adapt to survive in three radically different planetary environments.
The presence of real or apparent teleology in explanations of natural selection is a controversial aspect of the philosophy of biology, not least for its echoes of natural theology. [ 1 ] [ 7 ] The English natural theologian John Ray , and later William Derham , used teleological arguments to illustrate the glory of God from nature.
Aristotle's biology is the theory of biology, grounded in systematic observation and collection of data, mainly zoological, embodied in Aristotle's books on the science. Many of his observations were made during his stay on the island of Lesbos , including especially his descriptions of the marine biology of the Pyrrha lagoon, now the Gulf of ...
