That hypothesis is supported by the Columbia research, which showed that mice with high levels of osteocalcin activity were prevented from gaining weight or becoming diabetic even when they...Testosterone replacement therapy: How safe for aging men?

We can take away that effect by using antagonists that block the two cannabinoid receptors, which adds evidence that THC is the cu...Negative effects of plastic's additive blocked by nutrient supplements

The St. Jude researchers reasoned that if altering the position of the cilia in the fluid changes the ability of the cilia to amplify sound, then hearing should be affected when the mutant prestin made the cell extend itself. Therefore, the team developed a line of genetically modified mice that carr...Learning a second language -- Is it all in your head?

This change can be flicked back and forth like a light switch, says Dr. Jones, adding: Its remarkable.

Exploring the potential of biotherapy through oncolytic adenoviruses is a hot area in cancer research.

... particularly exciting about this approach is that altering an animal's genetic make-up seems able to slow down many diseases of ageing simultaneously," says Dr David Gems, a co-recipient of the award.
