Never observed anywhere in the bulge before, this peculiar "cocktail" of stars suggests that Terzan 5 is in fact one of the bulge's primordial building blocks, most likely the relic of a dwarf galaxy that merged with the Milky Way during its very early days. http://www.physorg.com/news178377940.html Space & Earth Wed, 25 Nov 2009 13:28:26 EST news178377940 (PhysOrg.com) -- What constitutes fish food is a matter of debate. A high-profile study a few years ago suggested that fish get almost 50 percent of their carbon from trees and leaves, evidence for a very close link between the terrestrial and aquatic ecosystems. http://www.physorg.com/news178280069.html Biology Tue, 24 Nov 2009 10:15:44 EST news178280069 (PhysOrg.com) -- A multi-trillion-watt laser at the University of Rochester has simulated a stellar jet -- an outpouring of matter from a fledgling star -- with unprecedented realism. http://www.physorg.com/news177949235.html Physics Fri, 20 Nov 2009 14:27:46 EST news177949235 (PhysOrg.com) -- As a clean energy alternative, NASA invented an algae photo-bioreactor that grows algae in municipal wastewater to produce biofuel and a variety of other products. http://www.physorg.com/news177780192.html Chemistry Wed, 18 Nov 2009 15:40:01 EST news177780192 If you eat fish to gain the heart-health benefits of its omega-3 fatty acids, baked or boiled fish is better than fried, salted or dried, according to research presented at the American Heart Association's Scientific Sessions 2009. http://www.physorg.com/news177694021.html Medicine & Health Tue, 17 Nov 2009 15:27:45 EST news177694021 Oil from soybeans modified through biotechnology increased levels of omega-3 eicosapentaenoic acid (EPA) in red blood cells according to research presented at the American Heart Association's Scientific Sessions 2009. http://www.physorg.com/news177621068.html Medicine & Health Mon, 16 Nov 2009 22:50:01 EST news177621068 Contrary to the findings of some studies, new research indicates that augmenting antidepressant therapy with an omega-3 fatty acid supplement does not result in improvement in levels of depression in patients with coronary heart disease, according to a study in the October 21 issue of JAMA. http://www.physorg.com/news175275685.html Medicine & Health Tue, 20 Oct 2009 17:20:01 EST news175275685 (PhysOrg.com) -- The negative impact of high amounts of methylmercury in seafood on blood pressure may outweigh the protective effects of fish nutrients, researchers report in Hypertension: Journal of the American Heart Association. http://www.physorg.com/news173983169.html Medicine & Health Mon, 05 Oct 2009 17:39:54 EST news173983169 Research led by Hernan A. Bazan, MD, Assistant Professor of Surgery, Section of Vascular Surgery, at LSU Health Sciences Center New Orleans School of Medicine, has found that unstable carotid artery plaques - those in danger of rupturing and leading to a stroke - contain more inflammation and significantly less omega-3 fatty acids than asymptomatic plaques. This suggests that increasing the levels of omega-3 fatty acids in carotid artery plaques could either prevent strokes or improve the safety of treatment. This may be accomplished by increasing dietary intake of foods rich in omega-3 fatty acids. http://www.physorg.com/news173620928.html Medicine & Health Thu, 01 Oct 2009 13:20:02 EST news173620928 (PhysOrg.com) -- CSIRO research on grains and lamb aimed at developing new dietary sources of long-chain omega-3 oils will be presented at the World Congress on Oils and Fats in Sydney this week. http://www.physorg.com/news173350145.html Medicine & Health Mon, 28 Sep 2009 10:00:01 EST news173350145 Aquaculture, once a fledgling industry, now accounts for 50 percent of the fish consumed globally, according to a new report by an international team of researchers. And while the industry is more efficient than ever, it is also putting a significant strain on marine resources by consuming large amounts of feed made from wild fish harvested from the sea, the authors conclude. Their findings are published in the Sept. 7 online edition of the Proceedings of the National Academy of Sciences (PNAS). http://www.physorg.com/news171564523.html Biology Mon, 07 Sep 2009 17:49:39 EST news171564523 A team of French scientists have found the dose of DHA (docosahexaenoic acid) that is "just right" for preventing cardiovascular disease in healthy men. In a research report appearing in the September 2009 print issue of The FASEB Journal, the scientists show that a 200 mg dose of DHA per day is enough to affect biochemical markers that reliably predict cardiovascular problems, such as those related to aging, atherosclerosis, and diabetes. This study is the first to identify how much DHA is necessary to promote optimal heart health. http://www.physorg.com/news170938612.html Biology Mon, 31 Aug 2009 13:30:03 EST news170938612 Hoping to broaden understanding about the benefits of Omega-3 fatty acids, a Purdue University-based international consortium has launched a Web site and newsletter campaign to educate the public, physicians and veterinarians. Bruce Watkins, Purdue professor of nutrition and director of the International Omega-3 Learning and Education Consortium for Health and Medicine, said most people know that Omega-3 fatty acids are good for them and can often name a few foods that contain them, but that's about it. http://www.physorg.com/news169926193.html Medicine & Health Wed, 19 Aug 2009 18:44:37 EST news169926193 Accumulating safety data from the large, international ORIGIN trial have been reviewed by its independent data monitoring committee, who have concluded that there is no cause for concern. http://www.physorg.com/news169201666.html Medicine & Health Tue, 11 Aug 2009 09:40:01 EST news169201666 There is mounting evidence that omega-3 fatty acids from fish or fish oil supplements not only help prevent cardiovascular diseases in healthy individuals, but also reduce the incidence of cardiac events and mortality in patients with existing heart disease. A new study, published in the August 11, 2009, issue of the Journal of the American College of Cardiology, extensively reviews data from a broad range of studies in tens of thousands of patients and sets forth suggested daily targets for omega-3 consumption. http://www.physorg.com/news168539596.html Medicine & Health Mon, 03 Aug 2009 20:50:01 EST news168539596 Current research suggests that a diet high in omega-3 fatty acids may help prevent one of the leading causes of legal blindness among the elderly. The related report by Tuo et al, "A high omega-3 fatty acid diet reduces retinal lesions in a murine model of macular degeneration," appears in the August 2009 issue of the American Journal of Pathology. http://www.physorg.com/news167548837.html Medicine & Health Thu, 23 Jul 2009 06:21:43 EST news167548837 Consumers may be able to eat longer-lasting, potentially healthier fish fillets if research at Oregon State University makes its way to the supermarket. http://www.physorg.com/news166982443.html Chemistry Thu, 16 Jul 2009 17:01:18 EST news166982443 Most of us are aware of the potential health benefits of omega-3 found in fish oil and flax seed.
