University of Pennsylvania School of Medicine researchers have described a previously unknown biological mechanism in cells that prevents them from cannibalizing themselves for fuel.

AMP-activated protein kinase, or AMPK, is a master regulator protein of metabolism that is conserved from yeast to humans. When a cell is low on fuel, AMPK shuts down processes that use energy and turns on processes that produce energy.

Investigators have found that fruit fly (Drosophila melanogaster) males -- in which the activity of an Alzheimer’s disease protein is reduced by 50 percent -- show impairments in learning and memory as they age.

Soccer referees may have an unconscious bias towards calling fouls based on a play’s direction of motion, according to a new study.
