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
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.

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

A high level of bullying was consistently associated with lower grades across the three years of middle school. ... > full story
Natural lung material is promising scaffold for engineering lung tissue using embryonic stem cells (August 20, 2010) -- Researchers report the first successful use of cell-depleted lung as a natural growth matrix for generating new rat lung from embryonic stem cells. ... > full story
Blood stem cell, leukemia link illuminated in new study (August 20, 2010) -- Scientists have discovered at least one key reason why blood stem cells are susceptible to developing the genetic mutations that can lead to adult leukemia. Their finding also may explain, they say, why some other age-related hematological disorders develop. ... > full story
Italian youths who drink with meals are less often adult problem-drinkers (August 20, 2010) -- Italian youths whose parents allowed them to have alcohol with meals while they were growing up are less likely to develop harmful drinking patterns in the future, according to a new study. ... > full story
