Greenland ice loss more ‘local’ than thought, climate study says
News from Los Angeles Times:
When it comes to melting ice on Greenland, climate change experts got everything right but the present.
That means Greenland’s contribution to sea level rise this century remains roughly the same – three inches – but where it comes from and how it gets to the ocean are now more clear, according to a new study that crunched 20 years of NASA data.
The findings will make climate models far more precise, according to the researchers.
Until now, the United Nation’s Intergovernmental Panel on Climate Change based its estimation of ice loss from Greenland on the four largest of an estimated 242 major outlet glaciers on that land mass, and admitted i……………. continues on Los Angeles Times
Scientists Find the Genes That Turned Horses Into Champions
News from NBCNews.com:
Using genomic analysis, scientists have identified DNA changes that helped turn ancient horses such as those in prehistoric cave art into today’s Secretariats. Understanding the genetic changes involved in equine domestication, which earlier research traced to the wind-swept steppes of Eurasia 5,500 years ago, has long been high on the wish list of evolutionary geneticists because of the important role that taming wild horses played in the development of civilization.
It was all made possible by 125 genes, according to a study in Proceedings of the National Academy of Sciences. Related to skeletal muscles, balance, coordination and cardiac strength, those genes produced traits so desirable that ancient breeders selected horses for them, said geneticist Ludovic Orlando of the Natural History Museum of Denmark, who led the study. The result was generations of horses adapted for chariotry, pulling plows and racing. Genes active in the brain also underwent selection. Variants linked to social behavior, learning, fear response and……………. continues on NBCNews.com
