A team of scientists, speaking today at the annual meeting of the American Association for the Advancement of Science, called for new awareness of the potential for antibiotic-resistant illnesses from the marine environment, and pointed to the marine realm as a source for possible cures of those threats. http://www.physorg.com/news153760926.html Space & Earth Fri, 13 Feb 2009 15:22:28 EST news153760926 According to a recent study published online in The FASEB Journal, diets rich in omega-3 fatty acids protect the liver from damage caused by obesity and the insulin resistance it provokes. This research should give doctors and nutritionists valuable information when recommending and formulating weight-loss diets and help explain why some obese patients are more likely to suffer some complications associated with obesity. Omega-3 fatty acids can be found in canola oil and fish. http://www.physorg.com/news153672709.html Medicine & Health Thu, 12 Feb 2009 14:54:21 EST news153672709 Researchers in the Department of Chemistry at Wake Forest University in collaboration with colleagues at the Wake Forest University Health Sciences Comprehensive Cancer Center have developed a new class of platinum-based anti-tumor drugs that animal studies have shown to be 10 times more effective than current treatments in destroying certain types of lung cancer cells. http://www.physorg.com/news153595851.html Chemistry Wed, 11 Feb 2009 17:31:18 EST news153595851 AUGUSTA, Ga. - Knocking out one gene that contributes to insulin resistance appears to prevent much of the cardiovascular damage typically associated with obesity, researchers say. http://www.physorg.com/news153578790.html Medicine & Health Wed, 11 Feb 2009 12:49:21 EST news153578790 Even the most drug-resistant fungi can be eradicated in multiple in vitro and in vivo models using a lethal combination of an antifungal agent and inhibition of the heat shock protein Hsp90, according to a new study by Whitehead Institute and University of Toronto researchers.

The genome data will aid scientists in optimizing sorghum and other crops not only for food and fodder use, but also for biofuels production. The comparative analysis of the sorghum genome appears in the January 29 edition of the journal Nature. http://www.physorg.com/news152370854.html Biology Wed, 28 Jan 2009 13:14:41 EST news152370854 Sedentary, obese older adults appear to improve their functional abilities and reduce insulin resistance through a combination of resistance and aerobic exercises, according to a report in the January 26 issue of Archives of Internal Medicine. http://www.physorg.com/news152210230.html Medicine & Health Mon, 26 Jan 2009 16:37:57 EST news152210230 (PhysOrg.com) -- Every year, millions of people are diagnosed with cancer - a remarkably high number. But what about the flipside of those statistics? That is, two out of three people never get cancer, and more than half of heavy smokers don`t get cancer, either. A recent study points out this overlooked fact, and suggests that researchers might discover something by asking why so many people are resistant to the often deadly disease. http://www.physorg.com/news151840958.html Medicine & Health Thu, 22 Jan 2009 10:03:13 EST news151840958 With an epidemic of antibiotic-resistant infections growing, experts are warning grocery-store pharmacies that antibiotics giveaways are an unhealthy promotional gimmick. If grocery stores want to help customers and save them money during cold and flu season, the Infectious Diseases Society of America (IDSA) says, they should offer free influenza vaccinations instead. http://www.physorg.com/news151328826.html Medicine & Health Fri, 16 Jan 2009 11:47:06 EST news151328826 Patients with peripheral arterial disease (PAD), which can include symptoms such as pain in the legs, who participated in supervised treadmill exercise improved their walking endurance and quality of life, according to a study in the January 14 issue of JAMA.

The research, funded by the Wellcome Trust and the Biotechnology and Biological Sciences Research Council (BBSRC), sheds light on how antibiotic resistance genes spread from one bacterium to another. The research may help scientists develop novel treatments for these diseases and novel ways to curtail the spread of antibiotic resistance. http://www.physorg.com/news150646319.html Medicine & Health Thu, 08 Jan 2009 14:11:59 EST news150646319 (PhysOrg.com) -- Dartmouth engineering professor and entrepreneur Victor Petrenko -along with his colleagues at Dartmouth and at Ice Engineering LLC in Lebanon, N.H. -have invented a way to cheaply and effectively keep ice off power lines. http://www.physorg.com/news150566568.html Technology Wed, 07 Jan 2009 16:02:48 EST news150566568 A new calibration tool was recently developed to help students and soil scientists calibrate their thumb and forefinger for the correct amount of pressure. http://www.physorg.com/news150374256.html Space & Earth Mon, 05 Jan 2009 10:37:36 EST news150374256 It's as simple as A, T, G, C.

Because abnormal glucose levels may indicate risk for diabetes or diabetes itself, these children could benefit from screening tests and diabetes prevention education. http://www.physorg.com/news148067860.html Medicine & Health Tue, 09 Dec 2008 17:57:40 EST news148067860 (PhysOrg.com) -- In less than an hour, the immune system of the beetle Tenebrio molitor neutralizes most of the bacteria infecting its hemolymph (the equivalent to blood in vertebrates); this is rendered possible by a cascade of ready-to-use cells and enzymes. Bacteria that resist these "front-line" defenses are then dealt with by antimicrobial peptides - a sort of natural antibiotic - which halt their proliferation. http://www.physorg.com/news146925795.html Biology Wed, 26 Nov 2008 12:43:15 EST news146925795
