Breakthrough in worm research has implications for human disease studies

RENO, Nev. -- It's just a worm, a tiny soil-dwelling nematode worm -- but the implications are big for biomedicine and circadian biology as shown in a recent study authored by University of Nevada, Reno researcher Alexander van der Linden. The art...

Biologists discover biochemical link between biological clock and diabetes

Biologists have found that a key protein that regulates the biological clocks of mammals also regulates glucose production in the liver and that altering the levels of this protein can improve the health of diabetic mice. Their discovery, detailed...
