Cells re-energize to come back from the brink of death

The discovery of how some abnormal cells can avoid a biochemical program of self-destruction by increasing their energy level and repairing the damage, is giving investigators at St. Jude Children's Research Hospital insights into a key strategy cancer cells use to survive and thrive. The finding of...

ASU research shows connection between testosterone, dietary antioxidants and bird coloration

... nutrient specific mechanisms by which animals can avoid the immune costs of testosterone elevation and still keep their attractive and bright colors,” McGraw said. Most previous studies of this sort have focused on physiological or even genetic links between testosterone and health. He adds that it is wor...

In this way, he said, physicians might avoid the usual pitfall involved in transplanting cells or organs from other people — organ rejection, which requires organ recipients to take immune-suppressing drugs for the rest of their lives. Huge numbers of stem cells are thought to be required to...
