Study shows more genes are controlled by biological clocks
The tick-tock of your biological clock may have just gotten a little louder. Researchers at the University of Georgia report that the number of genes under control of in living things than suspected only a few years ago. view more (2008-08-29)
Molecular sleuths track evolution through the ribosome
A new study of the ribosome, the cell's protein-building machinery, sheds light on the oldest branches of the evolutionary tree of life and suggests that differences in ribosomal structure between the three main branches of that tree are "molecular fossils" of the early evolution of protein synthesis. view more (2008-08-19)
Ricin's Deadly Action Revealed by Glowing Probes
A new chemical probe can rapidly detect ricin, a deadly poison with no known antidote that is feared to be a potential weapon for terrorists and cannot quickly be identified with currently available tests. view more (2008-08-07)
Researchers reveal insights into hidden world of protein folding
The proteins upon which life depends share an attribute with paper airplanes: Unless folded properly, they just won't fly. view more (2008-06-12)
UIC scientists discover how some bacteria survive antibiotics
Researchers at the University of Illinois at Chicago have discovered how some bacteria can survive antibiotic treatment by turning on resistance mechanisms when exposed to the drugs. The findings, published in the April 24 issue of the journal Molecular Cell, could lead to more effective antibiotics to treat a variety of infections. view more (2008-05-01)
