Just a few days of eating a diet high in saturated fat could be enough to cause memory problems and related brain inflammation in older adults, a new study in rats suggests.

Researchers at UC San Francisco have enabled a man who is paralyzed to control a robotic arm through a device that relays signals from his brain to a computer.  

He was able to grasp, move and drop objects just by imagining himself performing the actions.  

Investigators have found that the gene Asah1 plays a crucial protective role in preventing the progression of nonalcoholic fatty liver diseases (NAFLD) into more severe forms of liver disease by regulating hepatic lipid homeostasis and cellular maintenance processes. The findings from the new study in The American Journal of Pathology, published by Elsevier, have the potential to inform new therapeutic strategies and improve outcomes for NAFLD patients.
