Recently, Malaysian herpetologist Juliana Senawi puzzled over an unfamiliar orange-striped, yellow-speckled frog she’d live-caught in swampland on the Malay Peninsula. She showed the frog to Chan Kin Onn, a fellow herpetologist pursuing his doctorate at the University of Kansas. They wondered—was this striking frog with an appearance unlike others nearby in the central peninsula an unidentified species? Extensive genetic analysis…
The human brain can judge the apparent trustworthiness of a face from a glimpse so fleeting, the person has no idea they have seen it, scientists claim. Researchers in the US found that brain activity changed in response to how trustworthy a face appeared to be when the face in question had not been consciously perceived. Scientists made the surprise…
Large flesh-eating dinosaurs evolved into small flying birds, but it did not happen overnight. An international team of scientists on Thursday described an extraordinary evolutionary process that unfolded over a period of 50 million years in which a lineage of carnivorous dinosaurs shrank steadily and acquired numerous traits that led to the first appearance of birds. The researchers, using techniques…
ISG Associate Professor, Hannah Landecker, will be speaking at – EPIGENomics and Health Policy: Challenges and Opportunities December 1-3, 2014 IEO, via Adamello 16, Milan, Italy INTRODUCTION The rise of epigenomics has been exponential over the last decade, in terms of scientific breakthroughs and technological advances as well as in the public salience of its discourse. Its impact is particularly promising…
The classic definition of a biological species is the ability to breed within its group, and the inability to breed outside it. For instance, breeding a horse and a donkey may result in a live mule offspring, but mules are nearly always sterile due to genomic incompatibility between the two species. The vast majority of the time, mating across species…
ISG Associate Professor, Aaron Panofsky, is pleased to announce that his book Misbehaving Science: Controversy and the Development of Behavior Genetics is now out! Behavior genetics has always been a breeding ground for controversies. From the “criminal chromosome” to the “gay gene,” claims about the influence of genes like these have led to often vitriolic national debates about race, class,…
