July 16, 2012
Yeast cells yearning for a “soul mate” have a problem: They lack the ability to move on their own. To get closer to a potential mate, all they can do is reach out with cellular extensions. This enables a pair of yeast cells to make contact, after which they fuse their membra...

July 17, 2012
What’s good news for one might spell disaster for another. In cancer for instance, when a certain cell is commanded to grow and divide without restraint, it’s a welcome message for the cell itself but a tragedy for the person who harbors this cell in his or her bo...

July 24, 2012
Microprocessors – at least in the cell – are complexes that chop active, non-protein-coding strands called microRNAs (miRNA) out of longer, inactive precursor miRNA strands. These functional miRNAs regulate protein production by inhibiting the capacity of th...

July 24, 2012
The bacterium Clostridium thermocellum and a handful of close relatives are the only organisms known to break down one of the hardest materials in nature – the cellulose found in trees and tough, woody plants. This unique ability could be quite valuable: Sci...
