(PhysOrg.com) -- A team of astronomers, led by Loretta Dunne from the University of Nottingham, have found some very unusual stardust. In a paper to be published in Monthly Notices of the Royal Astronomical Society, Dr Dunne and her team find new evidence for the production of copious quantities of dust in the Cassiopeia A supernova remnant, the remains of a star that exploded about 300 years ago. http://www.physorg.com/news154709258.html Space & Earth Tue, 24 Feb 2009 14:48:14 EST news154709258 It is estimated that 4 million people world-wide are suffering from Parkinson's, a complex disease that varies greatly among affected individuals. Understanding the brain chemistry that leads to the onset of Parkinson's is vital if we are to develop methods for early MRI diagnosis and new treatments for this devastating disease. http://www.physorg.com/news153831792.html Medicine & Health Sat, 14 Feb 2009 11:05:21 EST news153831792 (PhysOrg.com) -- In the early Universe, some galaxies may have had stars packed together a hundred times more closely than in the present day, according to research by a University of Bonn team to be published in a paper in Monthly Notices of the Royal Astronomical Society.( http://www.physorg.com/news153679859.html Space & Earth Thu, 12 Feb 2009 16:51:37 EST news153679859 (PhysOrg.com) -- New research conducted in part by researchers at The George Washington University has led to novel insights into how feeding and dietary adaptations may have shaped the evolution of the earliest humans. http://www.physorg.com/news152859468.html Other Sciences Tue, 03 Feb 2009 04:58:12 EST news152859468 Over the past decade, two-thirds of Indiana growers have shifted to planting their soybean crop earlier because they believe that earlier planting increases yield. Planting date is probably one of the most important yet least expensive management decisions that significantly affects soybean yield. Few scientists, however, have studied the effect of early-planting dates on soybean yield components and the impact of early planting on seed composition. http://www.physorg.com/news152804395.html Other Sciences Mon, 02 Feb 2009 13:40:29 EST news152804395 Yale School of Medicine researchers have identified proteins associated with early onset neonatal sepsis (EONS), a stealthy bacterial infection linked to premature birth, illness and death. Using protein analysis, the researchers have found the biomarkers that can provide key information on how EONS develops. http://www.physorg.com/news152470600.html Medicine & Health Thu, 29 Jan 2009 16:57:12 EST news152470600 Scientists seek to create reliable early warning systems that accurately estimate the magnitude of an earthquake within the first seconds of rupture. In this paper published by the Bulletin of the Seismological Society of America, authors S. Murphy of University College Dublin, Ireland and S. Nielsen of the Instituto Nazionale di Geofisica e Vulcanologia, Roma, Italy look at the idea that an earthquake's final size can be determined during its initiation, rather than something that only becomes apparent at the end of the rupture. http://www.physorg.com/news152375731.html Space & Earth Wed, 28 Jan 2009 14:35:53 EST news152375731 (PhysOrg.com) -- An alternative proposal to dark energy in which the Earth sits near the center of a large void is undergoing scrutiny, and the results show that void models fit poorly with observed data. Nevertheless, scientists say that more research will be needed to determine if void models, dark energy, or something else can accurately explain how the universe is expanding at an accelerating rate. http://www.physorg.com/news152374990.html Physics Wed, 28 Jan 2009 14:23:51 EST news152374990 (PhysOrg.com) -- `Mom always liked you best.` The Smothers Brothers aside, chances are if you`ve got a sibling, this is something you`ve either heard or said at some point in your life. Many people feel that their parents were harder on them than on their siblings.

Alternatively, a parent's positive influence may go a long way to reduce risky sexual behavior during adolescence, according to Myeshia Price and Dr. Janet Hyde from the University of Wisconsin in the USA. Their findings have just been published online in Springer's Journal of Youth and Adolescence. http://www.physorg.com/news146745891.html Other Sciences Mon, 24 Nov 2008 10:44:51 EST news146745891 The human foot is a miracle of evolution. We can keep striding for miles on our well-sprung feet. There is nothing else like them, not even amongst our closest living relatives. According to Evie Vereecke, from the University of Liverpool, the modern human foot first appeared about 1.8 million years ago, but our ape-like ancestors probably took to walking several million years earlier, even though their feet were more 'floppy' and ape like than ours. http://www.physorg.com/news146139176.html Biology Mon, 17 Nov 2008 10:12:56 EST news146139176 The positive U.S. health trend documented over the past 30 years of reduction in risk for heart disease is not as strong as is widely perceived - and, in fact, the trend has flattened, according to a new analysis of national data by Mayo Clinic. http://www.physorg.com/news145627689.html Medicine & Health Tue, 11 Nov 2008 12:08:09 EST news145627689 The newly implemented Tsunami Early Warning System for the Indian Ocean, GITEWS, goes into operation today and with this, the system enters its final phase of optimisation.

A new study, published in the open access journal BMC Public Health, shows no significant decrease in alcohol-related attendances after 24-hour drinking was introduced but a significant shift in the time of attendances. http://www.physorg.com/news144651443.html Medicine & Health Fri, 31 Oct 2008 05:57:23 EST news144651443 A study initiated by researchers at Columbia University Mailman School of Public Health and the Leiden University Medical Center in the Netherlands suggests that prenatal exposure to famine can lead to epigenetic changes that may affect a person's health into midlife. The findings show a trickle-down effect from pregnant women to the DNA of their unborn children and the timeframe over which such early damage can operate. While previous studies have suggested that adult disease risk may be associated with adverse environmental conditions early in development, these data are the first to show that early-life environmental conditions can cause epigenetic changes in humans that persist throughout life. The full study findings are published online in the Proceedings of the National Academy of Science. http://www.physorg.com/news144598464.html Medicine & Health Thu, 30 Oct 2008 15:14:24 EST news144598464
