Gene linked to rare disease activates fat breakdown

...lycerides. In vertebrates including humans, excess nutritional carbohydrates and fat are efficiently converted into triglycerides and deposited in fat tissue. The team, led by Rudolf Zechner of the University of Graz in Austria, now reports that CGI-58 boosts the activity of so-called adipose triglyceride lipa...

Biologists find regions of rice domestication

...esearchers can consider ways to improve the crop's nutritional value and disease resistance, which in turn can help impoverished populations in Asia and elsewhere that rely heavily on the crop. Londo expects to find even more evidence for differing geographic domestication. He said that by using the database t...

Basic work on E. coli identifies two new keys to regulation of bacterial gene expression
