The long-held idea that only vertebrates have sophisticated adaptive immune systems that can protect them for life against many pathogens after being infected by them just once has been revised in…

Finally, a win for human embryonic stem cells (hESCs). Mice whose skulls were made whole again by bone tissue grown from hESCs shows that healing critical-size defects (defects that would not…

An effective and sensitive new method for detecting and characterizing prions, the infectious compounds behind diseases like mad cow disease, is now being launched by researchers at Linköping…

Acclaimed stem cell researcher Shinya Yamanaka, MD, PhD, has reported that he and his Kyoto University colleagues have successfully reprogrammed human adult cells to function like pluripotent…

There's always been speculation that human embryonic stem cell research was not worth the controversy due to uncertainty about their value in research and objections from womens' rights groups on one…

MIT researchers have identified a family of proteins key to the formation of the communication networks critical for normal brain function. Their research could lead to new treatments for brain…

It’s well known that the body’s energy levels cycle on a 24-hour, or circadian, schedule, and that this metabolic process is fueled by oxygen. Now, researchers at the University of Pennsylvania…

The cells which thicken the womb wall during a woman's menstrual cycle contain a newly discovered type of stem cell, and could be used in the treatment of damaged and/or old tissue, according to…
