Researchers discover underwater volcano

.... Much of Nafanua is covered with yellow "fluff," microbial aggregations that are produced by microscopic life feeding on chemical energy from the volcano's hydrothermal system. As Staudigel and his international team explored the area, they discovered a number of large communities of eels inhabiting the frag...

Scientists discover how plants disarm the toxic effects of excessive sunlight

...s a host defense to inhibit the growth of unwanted microbial pathogens. In fact, it appears that even non-photosynthetic bacteria, including human and animal pathogens like Vibrio and Pseudomonads have systems to sense and protect themselves from singlet oxygen, says Donohue. Other reactive oxygen species - of...

Transgenic plants remove more selenium from polluted soil than wild plants, new tests show

...he lab," said Norman Terry, professor of plant and microbial biology at UC Berkeley's College of Natural Resources and co-lead author of the study. "It turns out that our field test results were better than those from the greenhouse, and that was a surprise." In California, as much as 100,000 cubic meters of ...

Scientists solve structure of key protein in innate immune response

...ses the CD14 receptor protein to recognize several microbial and cellular products including lipopolysaccharide (LPS), a glycolipid found on the outer membrane of certain bacteria. Once CD14 binds to LPS or another ligand, it presents the molecule to other proteins which initiate a strong pro-inflammatory resp...

Examination of internal 'wiring' of yeast, worm, and fly reveals conserved circuits
