June 18, 2015 — DNA from the 8,500-year-old skeleton of an adult man found in 1996, in Washington, is more closely related to Native American populations than to any other population in the world, according to an ... read more

June 18, 2015 — Scientists have provided the first direct experimental evidence for how primordial proteins developed the ability to accelerate the central chemical reaction necessary to synthesize proteins and thus ... read more

Data Bank Launched for Global Access to Ancient DNA

June 17, 2015 — Medical and other researchers and science teachers around the world will be able to compare ancient DNA from humans from thousands of years ago with the genetics of modern day humans, thanks to a new ... read more

June 11, 2015 — Funnel-web spider venom contains powerful neurotoxins that instantly paralyze prey (usually insects). Millions of years ago, however, this potent poison was just a hormone that helped ancestors of ... read more

Eukaryotes: A New Timetable of Evolution

June 3, 2015 — The first single-celled organisms with a nucleus originated more than a billion years later than biogeochemical evidence had previously indicated. In contrast to prokaryotes such as bacteria, ... read more

June 1, 2015 — New research shows that the close linkage between the physical properties of amino acids, the genetic code, and protein folding was likely the key factor in the evolution from building blocks to ... read more

Ancient DNA Sheds Light on How Past Environments Affected Ancient Populations

May 28, 2015 — For the first time, a study shows that epigenetic marks on DNA can be detected in a large number of ancient human remains, which may lead to further understanding about the effects of famine and ... read more
