Some trees 'farm' bacteria to help supply nutrients

7/29/2010
Some trees growing in nutrient-poor forest soil may get what they need by cultivating specific root microbes to create compounds they require. These microbes are exceptionally efficient at turning inorganic minerals into nutrients that the trees can use. Researchers from France report their findings in the July 2010 issue of the journal Applied and Environmental Microbiology . "In acidic... [Comments]

Polymer passage takes time

7/29/2010
HOUSTON (July 29, 2010) Polymer strands wriggle their way through nanometer-sized pores in a membrane to get from here to there and do their jobs. New theoretical research by Rice University scientists quantifies precisely how long the journey takes. That's a good thing to know for scientists studying the transport of RNA, DNA and proteins -- all of which count as polymers -- or those w... [Comments]

Scientists post lower speed limit for cell-signaling protein assembly

7/29/2010
EAST LANSING, Mich. The apparently random self-assembly of molecular threads into the proteins that make the body work is far less frantic than previously thought, Michigan State University scientists say. That discovery could be a key to help unlock the nature of some diseases. How protein... [Comments]Scientists post lower speed limit for cell-signaling protein assembly

Mechanism uncovered behind Salmonella virulence and drug susceptibility

7/29/2010
Researchers have discovered a novel mechanism in Salmonella that affects its virulence and its susceptibility to antibiotics by changing its production of proteins in a previously unheard of manner. This allows Salmonella to selectively change its levels of certain proteins to respond to... [Comments]Mechanism uncovered behind Salmonella virulence and drug susceptibility

7/29/2010
MEDFORD/SOMERVILLE, Mass. -- Tougher than a bullet-proof vest yet synonymous with beauty and luxury, silk fibers are a masterpiece of nature whose remarkable properties have yet to be fully replicated in the laboratory. Thanks to their amazing mechanical properties as well as their looks,... [Comments]Behind the secrets of silk lie high-tech opportunities

HPC for phylogenetics tutorial aims to reduce analysis time

7/29/2010
A phylogenetic analysis can take a long time to run, but there are ways to do it more efficiently and effectively. The National Institute for Mathematical and Biological Synthesis (NIMBioS) will co-host a tutorial Oct. 13-15 focusing on high performance computing (HPC) for phylogenetics. "Fast, Free Phylogenies: HPC for Phylogenetics" focuses on how to use TeraGrid, the CIPRES Portal, the... [Comments]

Study finds black carbon implicated in global warming

7/29/2010
Increasing the ratio of black carbon to sulfate in the atmosphere increases climate warming, suggests a study conducted by a University of Iowa professor and his colleagues and published in the July 25 issue of the journal Nature Geoscience . Black carbons -- arising from such sources as diesel engine exhaust and cooking fires -- are widely considered a factor in global warming and are... [Comments]

Resting brain activity associated with spontaneous fibromyalgia pain

7/29/2010
A recent study from researchers at Massachusetts General Hospital and University of Michigan provides the first direct evidence of linkage between elevated intrinsic (resting-state) brain connectivity and spontaneous pain intensity in patients with fibromyalgia (FM). This research shows an interaction of multiple brain networks, offering greater understanding of how pain arises. Details of th... [Comments]
