Old World monkeys have undergone a remarkable evolution in facial appearance as a way of avoiding interbreeding with closely related and geographically proximate species, researchers from New York University and the University of Exeter have found. Their research provides the best evidence to date for the role of visual cues as a barrier to breeding across species. “Evolution produces adaptations…
There was a time when parents of newborns were perfectly content to know only a few basic things about their babies: their height, their weight, their apgar score, and which side of the family should get the credit for making the kid so adorable. But a graduate student at the University of California, Davis named Razib Khan wanted to know…
Congratulations, Class of 2014. Wishing each of you the best in your future endeavors! -The Institute for Society and Genetics
A team of Stanford University investigators has linked a particular brain circuit to mammals’ tendency to interact socially. Stimulating this circuit — one among millions in the brain — instantly increases a mouse’s appetite for getting to know a strange mouse, while inhibiting it shuts down its drive to socialize with the stranger. The new findings, published June 19 in…
Single Dose of Century-Old Drug Approved for Sleeping Sickness Reverses Autism-Like Symptoms in Mice
In a further test of a novel theory that suggests autism is the consequence of abnormal cell communication, researchers at the University of California, San Diego School of Medicine report that an almost century-old drug approved for treating sleeping sickness also restores normal cellular signaling in a mouse model of autism, reversing symptoms of the neurological disorder in animals that…
What do you get when you mix theorists in computer science with evolutionary biologists? You get an algorithm to explain sex. It turns out that 155 years after Charles Darwin first published “On the Origin of Species,” vexing questions remain about key aspects of evolution, such as how sexual recombination and natural selection produced the teeming diversity of life that…
