Cancer protein's surprising role as memory regulator (September 23, 2011) -- Scientists have found that a common cancer protein leads a second, totally different life in normal adult brain cells: It helps regulates memory formation and may be implicated in Alzheimer's disease. ... > full story

No harm to mice testes from BPA in utero: Data on female mice less encouraging (September 23, 2011) -- Male mice whose mothers were exposed to either moderate or high levels of bisphenol A while pregnant did not grow up to show any adverse effects to their reproductive systems by several measures, according to a new study. Data on female mice is still forthcoming but less encouraging. ... > full story

Researchers pinpoint the cause of MRI vertigo: Machine's magnetic field pushes fluid in the inner ear's balance organ (September 23, 2011) -- A team of researchers says it has discovered why so many people undergoing magnetic resonance imaging (MRI), especially in newer high-strength machines, get vertigo, or the dizzy sensation of free-falling, while inside or when coming out of the tunnel-like machine. ... > full story

Humor as effective as medication in treating agitation in dementia (September 23, 2011) -- Humor therapy is as effective as widely used antipsychotic drugs in managing agitation in patients with dementia -- and avoids serious drug side effects, a new study shows. ... > full story

Some brain wiring continues to develop well into our 20s (September 23, 2011) -- The human brain doesn't stop developing at adolescence, but continues well into our 20s, demonstrates recent research. It has been a long-held belief in medical communities that the human brain stopped developing in adolescence. But now there is evidence that this is in fact not the case. ... > full story

Combating obesity and diabetes: Researchers identify pathways leading to activation of 'good' fat (September 23, 2011) -- Researchers have identified for the first time two molecular pathways that are critical to activating a type of "good" fat found in the body, called brown fat, which actually burns energy rather than storing it, which the more common white fat does. The discovery could play an important role in the fight against obesity and diabetes. ... > full story

Mother’s occupation while pregnant can increase risk of asthma in children (September 23, 2011) -- Mothers who are exposed to particular agents during pregnancy could give birth to children with a higher risk of asthma, according to new research. ... > full story

Science and religion do mix? Only 15 percent of scientists at major research universities see religion and science always in conflict (September 23, 2011) -- Throughout history, science and religion have appeared as being in perpetual conflict, but a new study suggests that only a minority of scientists at major research universities see religion and science as requiring distinct boundaries. ... > full story

Decoding vaccination: Researchers reveal genetic underpinnings of response to measles vaccine (September 23, 2011) -- Researchers are hacking the genetic code that controls the human response to disease vaccination, and they are using this new cipher to answer many of the deep-seated questions that plague vaccinology, including why patients respond so differently to identical vaccines and how to minimize the side effects to vaccination. ... > full story

Kidney damage and high blood pressure: Faulty filtration allows detrimental enzymes to wreak havoc on fluid balance, research suggests (September 23, 2011) -- Scientists have now begun to understand kidney damage on a cellular level and how the activity of certain molecules in damaged kidneys contributes to salt and water retention in nephrotic syndrome. Several new insights in this area of research are presented at an upcoming meeting. ... > full story

One million more U.S. children living in poverty since 2009, new census data shows (September 23, 2011) -- Between 2009 and 2010, one million more children in America joined the ranks of those living in poverty, bringing the total to an estimated 15.7 million poor children in 2010, an increase of 2.6 million since the recession began in 2007, according to researchers. ... > full story

Scientists use brain imaging to reveal the movies in our mind (September 23, 2011) -- Imagine tapping into the mind of a coma patient, or watching one's own dream on YouTube. With a cutting-edge blend of brain imaging and computer simulation, scientists are bringing these futuristic scenarios within reach. Using functional Magnetic Resonance Imaging (fMRI) and computational models, researchers have succeeded in decoding and reconstructing people's dynamic visual experiences -- in this case, watching Hollywood movie trailers. ... > full story
