Geneticists of Leiden University Medical Centre (LUMC) are the first to determine the DNA sequence of a woman. She is also the first European whose DNA sequence has been determined. Following in-depth analysis, the sequence will be made public, except incidental privacy-sensitive findings. The results will contribute to insights into human genetic diversity.
Italian investigators have published a new study on the neurobiologic correlates of the inability to express emotions (alexithymia) in the third 2008 issue of Psychotherapy and Psychosomatics.
A species of wild yeast goes through a cycle of sexual reproduction once in every 1,000 asexual generations, according to new research by Imperial biologists published in the PNAS journal in April.
Silkworms have a unique ability to eat toxic mulberry leaves without feeling ill, and researchers have come one step closer to understanding why: silkworms contain a special digestive enzyme that is not affected by mulberry’s toxic chemicals.
The International Institute for Species Exploration at Arizona State University and an international committee of taxonomists — scientists responsible for species exploration and classification — has just announced the top 10 new species described in 2007.
Biologists have discovered that a fundamental building block in the cells of flowering plants evolved independently, yet almost identically, on a separate branch of the evolutionary tree–in an ancient plant group called lycophytes that originated at least 420 million years ago.
Research led by the University of Leeds has discovered genetic evidence that overturns existing theories about human migration into Island Southeast Asia (covering the Philippines, Indonesia and Malaysian Borneo) – taking the timeline back by nearly 10,000 years.
A statistical approach to studying genetic variation promises to shed new light on the history of human migration.
