Rice University scientists have detected at least three instances of cross-species mating that likely influenced the evolutionary paths of "old world" mice, two in recent times and one in the distant past. The researchers think these instances of introgressive hybridization -- a way for genetic material and, potentially, traits to be passed from one species…

NASA's Mars Curiosity rover has measured a tenfold spike in methane, an organic chemical, in the atmosphere around it and detected other organic molecules in a rock-powder sample collected by the robotic laboratory’s drill. "This temporary increase in methane -- sharply up and then back down -- tells us there must be some relatively localized…

The link between a mother and child is profound, and new research suggests a physical connection even deeper than anyone thought. The profound psychological and physical bonds shared by the mother and her child begin during gestation when the mother is everything for the developing fetus, supplying warmth and sustenance, while her heartbeat provides a…

One of the reasons cancer is so deadly is that it can evade attack from the body's immune system, which allows tumors to flourish and spread. Scientists can try to induce the immune system, known as immunotherapy, to go into attack mode to fight cancer and to build long lasting immune resistance to cancer cells. Now,…

The genetic material DNA can survive a flight through space and re-entry into Earth's atmosphere -- and still pass on genetic information. A team of scientists from UZH obtained these astonishing results during an experiment on the TEXUS-49 research rocket mission. Applied to the outer shell of the payload section of a rocket using pipettes,…

Looking across evolutionary time and the genomic landscapes of humans and mice, an international group of researchers has found powerful clues to why certain processes and systems in the mouse -- such as the immune system, metabolism and stress response -- are so different from those in people. Building on years of mouse and gene…
