Autism linked to multisensory integration (August 20, 2010) -- A new study has provided concrete evidence that children with autism spectrum disorders process sensory information such as sound, touch and vision differently than typically developing children. ... > full story

Frozen flies may yield secrets for human organ transplants (August 20, 2010) -- Frozen fruit fly cells may hold key to human organ transplant process, according to new research. ... > full story

Smart fungus disarms plant, animal and human immunity (August 20, 2010) -- Fungal and bacterial pathogens are well capable of infecting plants, animals and humans despite their immune systems. Fungi penetrate leafs, stalks and roots, or skin, intestines and lungs, to infect their hosts. Researchers have now discovered how this is possible. They found that the fungus secretes a protein that makes stray building blocks of the fungal cell wall invisible for the immune system of the plant. In this way infection remains unnoticed. ... > full story

Innovative imaging system may boost speed and accuracy in treatment of heart rhythm disorder (August 20, 2010) -- Researchers have developed a novel 3-D imaging approach that may improve the accuracy of treatment for ventricular tachycardia, a potentially life-threatening heart rhythm disorder that causes the heart to beat too fast. The new approach couples CT (computed tomography) images with conventional ablation techniques to eliminate erratic electrical circuits in the heart that produce arrhythmias. ... > full story

Mapping out pathways to better soybeans (August 20, 2010) -- Agricultural scientists are a step closer to unlocking genetic clues that may lead to packing more protein and oil into soybeans, a move that would boost their value and help US growers compete in international markets. ... > full story

Male menopause affects more than five million men (August 20, 2010) -- While most frequently associated with women's health, age-related hormone changes, often dubbed menopause, can occur in men as well, causing symptoms of fatigue, mood swings, decreased desire for sex, hair loss, lack of concentration and weight gain.

Is the ice in the Arctic Ocean getting thinner? (August 20, 2010) -- The extent of the sea ice in the Arctic will reach its annual minimum in September. Forecasts indicate that it will not be as low as in 2007, the year of the smallest area covered by sea ice since satellites started recording such data. Nevertheless, sea ice physicists are concerned about the long-term equilibrium in the Arctic Ocean. ... > full story

Cigarette smoke causes harmful changes in the lungs even at the lowest levels, study finds (August 20, 2010) -- Casual smokers may think that smoking a few cigarettes a week is "no big deal." But according to new research, having an infrequent smoke, or being exposed to secondhand smoke, may be doing more harm than people may think. The findings may further support public smoking bans, say the authors. ... > full story

Diabetes risk in children increases risk for weak bones (August 20, 2010) -- Children at risk for diabetes before they reach puberty also appear to be at risk for weak bones, researchers report. A study of 140 overweight children age 7-11 who got little regular exercise found that the 30 percent with signs of poor blood sugar regulation had 4-5 percent less bone mass, a measure of bone strength, said a bone biologist. ... > full story

Blood pressure drugs could help fight frailty, experiments show (August 20, 2010) -- Researchers believe they've found a way to use widely available blood pressure drugs to fight the muscular weakness that normally accompanies aging. ... > full story

Nanoscale inhomogeneities in superconductors explained (August 20, 2010) -- Superconducting materials, which transmit power resistance-free, are found to perform optimally when high- and low-charge density varies on the nanoscale level, according to new research. ... > full story

Victims of bullying suffer academically as well, psychologists report (August 20, 2010) -- Students who are bullied repeatedly do substantially worse in school, psychologists report. A high level of bullying was consistently associated with lower grades across the three years of middle school. ... > full story
