Use of the cholesterol-lowering drugs statins for more than a year is associated with a reduced risk of having gallstones requiring surgery, according to a study in the November 11 issue of JAMA. http://www.physorg.com/news177095898.html Medicine & Health Tue, 10 Nov 2009 17:20:21 EST news177095898 (PhysOrg.com) -- Scientists at North Carolina State University have effectively lifted the veil from the structure of an ancient and important RNA-protein complex essential for the biosynthesis and function of the ribosome, the protein-manufacturing machine of all cells. This RNA-protein enzyme performs a critical task in modifying the nucleotides of ribosomal RNA, modifications that are essential for protein synthesis. http://www.physorg.com/news171814779.html Biology Thu, 10 Sep 2009 16:10:02 EST news171814779 A new four-year, $3.72 million grant to North Carolina State University will allow researchers to shed light on an important mystery - how genes impact the type and amount of "glue," known as lignin, produced in trees. Understanding the role of lignin, which binds fibers together to form wood, has significant implications in the production of paper products, biofuels and construction materials. http://www.physorg.com/news171173463.html Biology Thu, 03 Sep 2009 05:11:36 EST news171173463 (PhysOrg.com) -- Researchers have not yet found a way to turn dirt into gold, but they are trying to find something valuable in it nonetheless: starting materials for novel pharmaceuticals. http://www.physorg.com/news168252027.html Chemistry Fri, 31 Jul 2009 10:00:01 EST news168252027 Cell biologists have found a more filling substitute for caloric restriction in extending the life span of simple organisms. In a study published May 8 in the open-access journal PLoS Genetics, researchers from the University of Southern California Andrus Gerontology Center show that yeast cells maintained on a glycerol diet live twice as long as normal -- as long as yeast cells on a severe caloric-restriction diet. They are also more resistant to cell damage. http://www.physorg.com/news160985198.html Biology Fri, 08 May 2009 07:07:17 EST news160985198 (PhysOrg.com) -- Making its home near extreme temperatures of thermal vents on the ocean floor, the organism Methanopyrus kandleri harbors a molecular secret that intrigues evolutionary biologists and even HIV researchers. http://www.physorg.com/news160326843.html Chemistry Thu, 30 Apr 2009 16:14:41 EST news160326843 Combating several human pathogens, including some biological warfare agents, may one day become a bit easier thanks to research reported by a University of Iowa chemist and his colleagues in the April 16 issue of the journal Nature. http://www.physorg.com/news159112477.html Biology Thu, 16 Apr 2009 14:55:03 EST news159112477 Researchers at Oregon State University have found one gene in the human body that appears to be a master regulator for skin development, in research that could help address everything from skin diseases such as eczema or psoriasis to the wrinkling of skin as people age. http://www.physorg.com/news157136390.html Medicine & Health Tue, 24 Mar 2009 18:00:30 EST news157136390 Scientists in the United Kingdom are reporting new evidence that humans can make their own salicylic acid (SA) - the material formed when aspirin breaks down in the body. SA, which is responsible for aspirin's renowned effects in relieving pain and inflammation, may be the first in a new class of bioregulators, according to a study in the December 24, 2008 issue of ACS' biweekly Journal of Agricultural and Food Chemistry. http://www.physorg.com/news151004405.html Chemistry Mon, 12 Jan 2009 17:40:05 EST news151004405
