Compounds that kill dormant pathogen while sparing human cells could lead to new drugs Attempts to eradicate tuberculosis (TB) are stymied by the fact that the disease-causing bacteria have a sophisticated mechanism for surviving dormant in infected cells. Now, a team of scientists including researchers from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, Stony Brook University (SBU), Weill Cornell Medical College, and The Rockefeller University has identified compounds...

Reveals shape-shifting atomic interactions; suggests mechanism and possible drug targets How much difference can a tenth of a nanometer make? When it comes to figuring out how proteins work, an improvement in resolution of that miniscule amount can mean the difference between seeing where atoms are and understanding how they interact. Case in point: New, improved-resolution views of a zinc transporter protein deciphered at the U.S. Department of Energy's Brookhaven National Laboratory provide...

An international team of scientists has discovered extensive similarities between a strain of bacteria commonly associated with plants and one increasingly linked to opportunistic infections in hospital patients. The findings suggest caution in the use of the plant-associated strain for a range of biotech applications. The genetic analysis was conducted in part at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, and will be published in the July 2009 issue of Nature...

In 1972, Apollo astronauts narrowly escaped a potential catastrophe. On August 2nd of that year, a large and angry sunspot appeared and began to erupt, over and over again for more than a week, producing a record-setting fusillade of solar proton radiation. Only pure luck saved the day. The eruptions took place during the gap between Apollo 16 and 17 missions, so astronauts missed the storm. Researchers still wonder, what would have happened if the timing had been just a little different,...

Duke and Brookhaven examine free-flowing 'exploding cigars' Several years after Duke University researchers announced spectacular behavior of a low density ultracold gas cloud, researchers at Brookhaven National Laboratory have observed strikingly similar properties in a very hot and dense plasma "fluid" created to simulate conditions when the universe was about one millionths of a second old. The plasma was formed at a colossal 2 million degrees Kelvin temperatures within Brookhaven's...

NIST, Brookhaven Researchers Use Tuberculosis Bacteria to End 25-Year Quest The bacterium behind one of mankind's deadliest scourges, tuberculosis, is helping researchers at the Commerce Department's National Institute of Standards and Technology (NIST) and the Department of Energy's Brookhaven National Laboratory (BNL) move closer to answering the decades-old question of what controls the switching on and off of genes that carry out all of life's functions. In a Journal of Biological...

Findings have implications for increasing biomass for the production of biofuels Through work originally designed to remove contaminants from soil, scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and their Belgium colleagues at Hasselt University have identified plant-associated microbes that can improve plant growth on marginal land. The findings, published in the February 1, 2009 issue of Applied and Environmental Microbiology, may help scientists design...

A team of scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, in collaboration with researchers from the University of Delaware and Yeshiva University, has developed a new catalyst that could make ethanol-powered fuel cells feasible. The highly efficient catalyst performs two crucial, and previously unreachable steps needed to oxidize ethanol and produce clean energy in fuel cell reactions. Their results are published online in the January 25, 2009 edition of...

New research may be able to explain why men are more capable of watching what they eat than women. Women's brains are at fault, researchers said in their report published in Proceedings of the National Academy of Sciences. "There is something going on in the female," lead researcher Gene-Jack Wang, of Brookhaven National Laboratory, told the Associated Press. "The signal is so much different." He and his colleagues compared the results of positron emission tomography (PET) brain scans from...

Mechanistic details revealed through unique light source technique Using two simultaneous light-based probing techniques at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, a team of researchers has illuminated important details about a class of enzymes involved in everything from photosynthesis to the regulation of biological clocks. The interdisciplinary team has a broad interest in flavoproteins, which were first discovered in the 1930s and derive from riboflavin, or...

Word of the Day
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
