Nature Related images(click to enlarge) Chimelong Safari Park White tigers today are only seen in zoos, but they belong in nature, say researchers reporting new evidence about what makes those tigers white. Their spectacular white coats are produced by a single change in a known pigment gene, according to the study, appearing on May 23 in Current Biology, a Cell Press publication. "The white tiger represents part of the natural genetic di Read more...

Credit: Albozagros The genetics and history of Tibet are fascinating to many. To be honest the primary reason here is elevation. The Tibetan plateau has served as a fortress for populations who have adapted biologically and culturally to the extreme conditions. Naturally this means that there has been a fair amount of population genetics on Tibetans, as hypoxia is a side effect of high altitude living which dramatically impacts fitness. I have Read more...

The carnivorous pitcher plant Nepenthes bicalcarata (A) and the ant Camponotus schmitzi (B) team up to fight fly larvae (C) that steal the plant’s prey. An insect-eating pitcher plant teams up with ants to prevent mosquito larvae from stealing its nutrients, according to research published May 22 in the open access journal PLOS ONE by Mathias Scharmann and colleagues from the University of Cambridge and the University Brunei Darussalam.

Byzantine Emperor Leo “the Khazar” with his son Constantine IV. Credit: Cplakidas For the past year or so I’ve been getting queries about what I think about Eran Elhaik’s preprint on the genetic character of European Jews. I found some of the conclusions frankly a little weird, but I assumed that things would be cleaned up for publication. Well, it’s been out for a while now: The Missing Link of Jewish European An Read more...
