Some obese people misperceive that their body size is normal and think they don't need to lose weight, according to research presented at the American Heart Association's Scientific Sessions 2009. http://www.physorg.com/news177702370.html Medicine & Health Tue, 17 Nov 2009 18:01:02 EST news177702370 Teenage women who are obese may be more than twice as likely to develop multiple sclerosis (MS) as adults compared to female teens who are not obese, according to a study published in the November 10, 2009, print issue of Neurology, the medical journal of the American Academy of Neurology. http://www.physorg.com/news177009035.html Medicine & Health Mon, 09 Nov 2009 17:20:04 EST news177009035 Former professional football players with large bodies don't appear to have the same risk factors for heart disease as their non-athletic counterparts, UT Southwestern Medical Center researchers have found in studying a group of National Football League (NFL) alumni. http://www.physorg.com/news173516557.html Medicine & Health Wed, 30 Sep 2009 08:30:02 EST news173516557 Male seahorses have a clear agenda when it comes to selecting a mating partner: to increase their reproductive success. By being choosy and preferring large females, they are likely to have more and bigger eggs, as well as bigger offspring, according to Beat Mattle and Tony Wilson from the Zoological Museum at the University of Zurich in Switzerland. Their findings have just been published online in Springer's journal Behavioral Ecology and Sociobiology. http://www.physorg.com/news166187324.html Biology Tue, 07 Jul 2009 12:30:01 EST news166187324 (PhysOrg.com) -- Milder winters are causing Scotland's wild breed of Soay sheep to get smaller, despite the evolutionary benefits of possessing a large body, according to new research due to be published in this week's Science Express (2 July). http://www.physorg.com/news165762932.html Biology Thu, 02 Jul 2009 14:15:56 EST news165762932 Large size and a fast bite spelled doom for bony fishes during the last mass extinction 65 million years ago, according to a new study to be published March 31, 2009, in the Proceedings of the National Academy of Sciences. http://www.physorg.com/news157294064.html Biology Thu, 26 Mar 2009 13:48:46 EST news157294064 Researchers at Columbia University Mailman School of Public Health examined the association of neighborhood food environments and "walkability" with body mass index (BMI) and obesity in New York City and found that a higher density of BMI-healthy food outlets is associated with a lower BMI and lower prevalence of obesity. BMI-unhealthy food stores and restaurants -- although far more abundant than healthy ones -- were not significantly associated with higher BMI or prevalence of obesity. The findings are published in the March 2009 issue of Environmental Health Perspectives. http://www.physorg.com/news156693412.html Medicine & Health Thu, 19 Mar 2009 14:58:10 EST news156693412 (PhysOrg.com) -- Somewhere out there in the ocean, SpongeBob SquarePants has a teeny-tiny cousin and a humongous uncle. http://www.physorg.com/news156540818.html Biology Tue, 17 Mar 2009 20:34:15 EST news156540818 The larger body size of professional football players doesn't increase risk of cardiovascular disease or atherosclerosis after they retire, according to research presented at the American Heart Association's Scientific Sessions 2008. http://www.physorg.com/news145626441.html Medicine & Health Tue, 11 Nov 2008 11:47:21 EST news145626441 Knee clicking can establish mating rights among antelopes. A study of eland antelopes, published in the open access journal BMC Biology, has uncovered the dominance displays used by males to settle disputes over access to fertile females, without resorting to genuine violence. http://www.physorg.com/news144959037.html Biology Mon, 03 Nov 2008 18:23:57 EST news144959037 Ever since Darwin, evolutionary biologists have wondered why some lineages have diversified more than others. A classical explanation is that a higher rate of diversification reflects increased ecological opportunities that led to a rapid adaptive radiation of a clade. http://www.physorg.com/news138003096.html Biology Fri, 15 Aug 2008 07:11:36 EST news138003096 After taking a fresh look at an old fossil, John Flynn, Frick Curator of Paleontology at the American Museum of Natural History, and colleagues determined that the brains of the ancestors of modern Neotropical primates were as small as those of their early fossil simian counterparts in the Old World. This means one of the hallmarks of primate biology, increased brain size, arose independently in isolated groups -the platyrrhines of the Americas and the catarrhines of Africa and Eurasia. http://www.physorg.com/news134820876.html Biology Wed, 09 Jul 2008 11:14:36 EST news134820876 Measuring and testing the teeth of living primates could provide a window into the behavior of the earliest human ancestors, based on their fossilized remains. Research funded by the National Science Foundation and led by University of Arkansas anthropologist Michael Plavcan takes us one step closer to understanding the relationship between canine teeth, body size and the lives of primates. http://www.physorg.com/news133709182.html Other Sciences Thu, 26 Jun 2008 14:26:22 EST news133709182
