How to weigh a star using a moon (October 16, 2010) -- How do astronomers weigh a star that's trillions of miles away and way too big to fit on a bathroom scale? In most cases they can't, although they can get a best estimate using computer models of stellar structure. An astrophysicist says that in special cases, we can weigh a star directly. ... > full story
Diagnosing autism with MRI is one step closer (October 16, 2010) -- Medical researchers have made an important step in diagnosing autism through using MRI, an advance that eventually could help health care providers identify the problem much earlier in children and lead to improved treatment and outcomes for those with the disorder. ... > full story
New data on effects of alcohol during pregnancy (October 16, 2010) -- Scientific data continue to indicate that higher intake of alcohol during pregnancy adversely affects the fetus, and could lead to very severe developmental or other problems in the child. However, most recent publications show little or no effects of occasional or light drinking by the mother during pregnancy. ... > full story
Low-cost weight loss program beats obesity, researchers find (October 16, 2010) -- In the battle against obesity, new research has found that it may not be necessary to spend a lot on a weight loss program when cheaper, nonprofit alternatives may work just as well. ... > full story
Studies of radiative forcing components: Reducing uncertainty about climate change (October 16, 2010) -- Much is known about factors that have a warming effect on Earth's climate -- but only a limited amount is understood about factors that have a cooling effect. Researchers in Norway are working to fill the knowledge gap by studying as many radiative forcing components as possible simultaneously. ... > full story
Happier to give than receive? (October 16, 2010) -- Is there a correlation between a nation's contributions to international aid programs and the happiness of its citizens? According to a study of nine European donor countries, there is a direct relationship between the level of foreign aid and level of happiness in the UK and France but for other European countries there seems to be no link.

Scientists discover new species in one of world’s deepest ocean trenches (October 16, 2010) -- Scientists investigating in one of the world's deepest ocean trenches -- previously thought to be void of fish -- have discovered an entirely new species. ... > full story
Flexing their muscles helps kidney disease patients live longer, study finds (October 16, 2010) -- Kidney disease patients are healthier and live longer if they've beefed up their muscles, according to a new study. The results suggest that patients may benefit from pumping iron or taking medications to boost their lean body mass. ... > full story
Cells able to switch genetic profile: Implications for cancer drug testing (October 16, 2010) -- Scientists have made a breakthrough in the way anti-cancer drugs are tested. A tumor cannot grow to a large size or spread until it has developed its own blood supply and leading research has looked for a way of halting capillary formation to stop tumors taking hold. But new findings have shown that scientists testing such treatments may not have been studying exactly what they thought they were. The research shows that cells are able to switch their genetic profile -- turning off genes expressed by blood vessel cells and turning on genes specific to lymphatic cells. ... > full story
Insight gained into age-related hearing loss (October 16, 2010) -- Researchers have gained insight into how different types of age-related hearing loss may occur in humans. The discovery could eventually help physicians develop drugs to combat progressive hearing loss. ... > full story
Unsung hero: Researchers produce high-res model of Ndc80 in action (October 16, 2010) -- Scientists have used cryo-electron microscopy and three-dimensional image reconstruction to create a subnanometer resolution image of Ndc80, a protein complex that helps prevent chromosomal distribution mistakes during mitosis that can lead to birth defects, cancer and other disorders. ... > full story
Improving sonography: Spatial ability is key to becoming a successful sonographer, study finds (October 16, 2010) -- Diagnostic ultrasounds are the most widely used medical tests in the world. Though the technology is more than 50 years old, scientists continue to discover new uses for it, ranging from more targeted cancer treatments to liposuction. As the technology becomes more complex, a sonographer's skill level is even more important. Now, researchers may have found one of the keys to becoming a successful sonographer: spatial ability. ... > full story
