As nonconventional medical treatments become increasingly mainstream, we take a look at the science behind some of the most popular.
On the Chain Gang
Keith D. Wilkinson and David Fushman | Jul 1, 2012
More than simply helping haul out a cell’s garbage, ubiquitin, with its panoply of chain lengths and shapes, marks and regulates many unrelated cellular processes.
Growing Better Biofuel Crops
Heather Youngs and Chris Somerville | Jul 1, 2012
Research is underway to reduce the use of food crops for biofuels by shifting to dedicated energy crops and agricultural residues.
