Nearly half of the human genome is composed of genetic parasites—transposons, plasmids, viruses, and other genetic elements that have one thing in common: they don't make any beneficial contributions to their hosts, and ...
In 2002, Secretary of state Donald Rumsfeld made a statement regarding weapons of mass destruction that today is still well known. He famously parsed the evidence (or lack thereof) into "known knowns, known unknowns, and ...
Researchers at the Chinese Academy of Agricultural Sciences, China, have applied machine learning to genetic sequence data from wild and domestic European grapes.
A team of researchers with members affiliated with several institutions in Japan has learned more about the process involved in the development of natural symbiotic relationships by engineering an artificial one between E. ...
Darwinian evolution is the process by which natural selection promotes genetic changes in traits that favor survival and reproduction of individuals. How fast evolution happens depends crucially on the abundance of its "fuel": ...
