A generally accepted 44-year-old assumption about how certain kinds of bacteria make energy and synthesize cell materials has been shown to be incorrect by a team of scientists led by Donald Bryant, the Ernest C. Pollard Professor of Biotechnology at Penn State University and a research professor in the Department of Chemistry and Biochemistry at Montana State University. The research, which will be published in the journal Science on 16 December 2011, is expected to help scientists discover...

Something rotten never smelled so sweet. This is what members of a team of scientists at Cold Spring Harbor Laboratory (CSHL) are telling one another as they discuss a new finding they did not expect to make. They have discovered that hydrogen sulfide (H2S) — the flammable, highly toxic gas that we usually associate with the smell of rotten eggs in landfills and sewers — plays an important role in the regulation of a signaling pathway implicated in biological malfunctions...

Researchers at the Stanford University School of Medicine report that they have identified the molecular pathway through which physical force contributes to scarring in mice. "Our study exposes one of the fundamental mechanisms by which the mechanical environment can directly increase inflammation, which is strongly implicated in scarring," said Geoffrey Gurtner, MD, professor and associate chair of surgery. Mice genetically engineered to lack an enzyme that is activated by mechanical...

Scientists at Warwick Medical School have made an important discovery about the mechanism controlling the body´s ℠fat switch´, shedding new light on our understanding of how proteins regulate appetite control and insulin secretion. This research, led by Professor Victor Zammit, Head of Metabolic and Vascular Health at Warwick Medical School, found that the enzyme known as ℠Carnitine palmitoyltransferase 1A´ (CPT1) has a switch which is thrown depending on the...

Findings explain the molecular basis for cherubism disease and may open new avenues for inhibiting Tankyrase function in cancer therapy The Samuel Lunenfeld Research Institute's Drs. Frank Sicheri, Tony Pawson and Sebastian Guettler, in collaboration with Dr. Robert Rottapel at the Ontario Cancer Institute, have uncovered the detailed architecture of a crucial component of Tankyrase, a protein linked to the bone development disorder cherubism and involved in a myriad of cellular processes....

Supercomputer simulations at the Department of Energy's Oak Ridge National Laboratory are giving scientists unprecedented access to a key class of proteins involved in drug detoxification. Jerome Baudry and Yinglong Miao, who are jointly affiliated with ORNL and the University of Tennessee, have performed simulations to observe the motions of water molecules in a class of enzymes called P450s. Certain types of P450 are responsible for processing a large fraction of drugs taken by humans....

Scientists at the European Commission's Joint Research Centre (JRC) have identified a shortlist of denaturants that could be used to harmonize denaturing practices at EU level and reduce fraud and tax evasion of alcoholic beverages. The proposed denaturants could potentially replace over 100 different substances currently used in Member States to denature alcohol. Denaturants are used to make alcohol unfit for human consumption and are therefore strong-smelling or bitter-tasting...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
