UT Knoxville and ORNL researchers turn algae into high-temperature hydrogen source

November 12, 2009

KNOXVILLE -- In the quest to make hydrogen as a clean alternative fuel source, researchers have been stymied about how to create usable hydrogen that is clean and sustainable without relying on an

Workplace BPA exposure increases risk of male sexual dysfunction

November 11, 2009

November 11, 2009 (Oakland, Calif.) -- High levels of workplace exposure to Bisphenol-A may increase the risk of reduced sexual function in men, according to a Kaiser Permanente study appearing in

Navy researchers apply science to fire fighting

November 2, 2009

A fire aboard a Navy ship can quickly become a deadly cauldron. The grim reminders of this would be the deadly fires that took place aboard the USS Forrestal in 1967 or the USS Enterprise in 1969.

Digital 'plaster' for monitoring vital signs undergoes first clinical trials

November 2, 2009

A wireless digital 'plaster' that can monitor vital signs continuously and remotely is being tried out with patients and healthy volunteers at Imperial College Healthcare NHS Trust, in a new clinic

2-pronged protein attack could be source of SARS virulence

October 29, 2009

GALVESTON, Texas -- Ever since the previously unknown SARS virus emerged from southern China in 2003, University of Texas Medical Branch at Galveston virologists have focused on finding the sourc

Researchers discover mechanism that prevents two species from reproducing

October 26, 2009

Cornell researchers have discovered a genetic mechanism in fruit flies that prevents two closely related species from reproducing, a finding that offers clues to how species evolve.

Manipulating brain inflammation may help clear brain of amyloid plaques, Mayo Clinic researchers say

October 22, 2009

JACKSONVILLE, Fla. -- In a surprising reversal of long-standing scientific belief, researchers at the Mayo Clinic campus in Florida have discovered that inflammation in the brain is not the trigger that leads to buildup of amyloid deposits and development of Alzheimer's disease.

Synthetic cells shed biological insights while delivering battery power

October 22, 2009

Trying to understand the complex workings of a biological cell by teasing out the function of every molecule within it is a daunting task. But by making synthetic cells that include just a few chemical processes, researchers can study cellular machinery one manageable piece at a time.

Genomes of 2 popular research strains of E. coli sequenced

October 20, 2009

Upton, NY -- An international team of researchers from the United States, Korea, and France has sequenced and analyzed the genomes of two important laboratory strains of E. coli bacteria, one used to study evolution and the other to produce proteins for basic research or practical applications.

ID3 provides career counseling for blood progenitors, driving the creation of gamma-delta T cells

October 15, 2009

Like an unusually forceful career counselor, the Id3 protein decides the fate of a given white blood cell precursor, according to researchers at Fox Chase Cancer Center. Their findings, published today in the journal Immunity, describe how Id3 directs blood cell progenitors to become gamma-delta T cells.

Researchers identify promising therapeutic target for central nervous system injuries

October 15, 2009

Boston, Mass. (Oct. 15) -- Scars can serve as double-edged swords in spinal cord injuries -- saving a victim's life, but sealing his or her fate as a paraplegic or quadriplegic. The scar forms a wall around the wound, preventing the injury from spreading, but limiting opportunities for neural regeneration.

Silence of the genes

October 13, 2009

BERKELEY, CA - The molecular architecture of a protein complex that helps determine the fate of human cells has been imaged for the first time by researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab).

Scientists decipher missing piece of first-responder DNA repair machine

October 1, 2009

BERKELEY, CA -- Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the Scripps Research Institute have uncovered the role played by the least-understood part of a first-responder molecule that rushes in to bind and repair breaks in DNA strands, a process that helps people avoid cancer.

Electric fish plug in to communicate

September 28, 2009

AUSTIN, Texas -- Just as people plug in to computers, smart phones and electric outlets to communicate, electric fish communicate by quickly plugging special channels into their cells to generate electrical impulses, University of Texas at Austin researchers have discovered.

Trial of new treatment for advanced melanoma shows rapid shrinking of tumors

September 23, 2009

Berlin, Germany: Researchers have made significant advances in the treatment of metastatic malignant melanoma -- one of the most difficult cancers to treat successfully once it has started to spread -- according to a study to be presented at Europe's largest cancer congress, ECCO 15 -- ESMO 34 [1], in Berlin on Thursday.
