Scientists discover small RNA that regulates bacterial infection

People with weakened immune systems are at constant risk of infection. Pseudomonas aeruginosa, a common environmental bacterium, can colonize different body parts, such as the lungs, leading to persistent, chronic infections ...

New strategy directly activates cellular 'death protein'

Researchers at Dana-Farber/Children's Hospital Cancer Center have devised a strategy to directly activate a natural "death" protein, triggering the self-destruction of cells. They say the development could represent a new ...

Single-DNA images give clues to breast cancer

For the first time, researchers at the University of California, Davis, have watched single strands of DNA being prepped for repair. The research, published this week in the journal Nature, has implications for understanding ...

New chemistry technique reproduces nature's elusive complexity

(Phys.org)—Scientists at The Scripps Research Institute have shown how to synthesize in the laboratory an important set of natural compounds known as terpenes. The largest class of chemicals made by living organisms, terpenes ...

Team applies new techniques and sees surprises in cell division

Researchers at the California Institute of Technology have obtained the first high-resolution, three-dimensional images of a cell with a nucleus undergoing cell division. The observations, made using a powerful imaging technique ...

Research predicts growth, survival of 'superorganism' ant colonies

(Phys.org)—Smaller ant colonies tend to live faster, die younger and burn up more energy than their larger counterparts, as do the individual ants that make up those colonies, according to new research that views the colonies ...

Cracking open a cell biology mystery

Two billion years ago somewhere in the primordial soup, one of our single-cell ancestors made a quick lunch out of another. But, in a moment of evolutionary serendipity, the would-be prey worked out a "win-win" symbiotic ...
