In mammals, hair follicles emerge during embryonic development, forming geometric patterns that vary from one species to another. But how is the position of each hair determined? A team from the University of Geneva (UNIGE) has shown that a simple mechanism based on the movement

A Cornell-led study is challenging a decades-old explanation for how chromosomes exchange genetic material within the biological process that forms eggs and sperm in mammals.

A tiny mouse living nearly 7,000 meters (23,000 feet) above sea level in the Andes is helping scientists rethink the limits of life on Earth. The animal, a leaf-eared mouse, is the focus of a new international study co-authored by McMaster University researchers, revealing how ma

Within every muscle of every living species with a backbone, a protein called myosin tugs on a partner protein to generate a muscle contraction. This function, discovered in mammals a century ago, has been presumed by scientists to operate the same way among birds, reptiles, amph
