Calcium pump motions captured in action

The pumping action of the calcium pump protein—an intricate molecular machine with several moving parts that helps control muscle contraction—has been detailed with exquisite precision by RIKEN biophysicists. By providing ...

Devices designed to identify pathogens in food

Researchers at the National Polytechnic Institute (IPN) in Mexico have developed a technology capable of identifying pathogens in food and beverages. This technique could work in the restaurant industry as a biosensor to ...

Histone exchanger comes into focus

The packaging of a gene has a major impact on its functional state and must be precisely controlled. A novel blend of methods has unveiled the architecture of a large protein complex that modulates DNA packing, and hints ...

Watching the cogwheels of the biological clock in living cells

Our master circadian clock resides in a small group of about 10'000 neurons in the brain, called the suprachiasmatic nucleus. However, similar clocks are ticking in nearly all cells of the body, as demonstrated by the group ...

Team views genome as it turns on and off inside cells

UCSF researchers have developed a new approach to decoding the vast information embedded in an organism's genome, while shedding light on exactly how cells interpret their genetic material to create RNA messages and launch ...

More Proof of Outer Membrane Cytochrome Role in Electron Transfer

(PhysOrg.com) -- Another step toward improving understanding of electron exchange between microbes and minerals has been documented in the January 2010 issue of Geobiology. Bacteria such as the metal-reducing Shewanella oneidensis ...
