Metabolic 'breathalyzer' reveals early signs of disease Posted: 06 Feb 2012 02:42 PM PST The future of disease diagnosis may lie in a "breathalyzer"-like technology currently under development.

School Closures Slow Spread of pH1N1 Posted: 06 Feb 2012 02:42 PM PST Using high-quality data about the incidence of influenza infections in Alberta during the 2009 H1N1 flu pandemic, the researchers show that when schools closed for the summer, the transmission of infection from person to person was sharply reduced.

Clues to common birth defect found in gene expression data Posted: 06 Feb 2012 12:41 PM PST Researchers have uncovered 27 new candidate genes for congenital diaphragmatic hernia, a common and often deadly birth defect. Their sophisticated data-filtering strategy offers a new, efficient and potentially game-changing approach to gene discovery.

Discovery predicts patient sensitivity to important drug target in deadly brain cancer Posted: 06 Feb 2012 11:41 AM PST A recent discovery enables the prediction of patient sensitivity to proposed drug therapies for glioblastoma – the most common and most aggressive malignant brain tumor in humans.

It's not solitaire: Brain activity differs when one plays against others Posted: 06 Feb 2012 11:39 AM PST Researchers have found a way to study how our brains assess the behavior -- and likely future actions -- of others during competitive social interactions. Their study is the first to use a computational approach to tease out differing patterns of brain activity during these interactions, the researchers report.

Exercise triggers stem cells in muscle Posted: 06 Feb 2012 11:39 AM PST Researchers have determined that an adult stem cell present in muscle is responsive to exercise, a discovery that may provide a link between exercise and muscle health. The findings could lead to new therapeutic techniques using these cells to rehabilitate injured muscle and prevent or restore muscle loss with age.

Why people can hold visual information in great detail in their working memory Posted: 06 Feb 2012 11:38 AM PST A new study may explain why people can hold visual information in great detail in their working memory.

Raw milk is a dangerous raw deal for farmers and consumers, experts say Posted: 06 Feb 2012 11:38 AM PST Researchers and experts on food safety have commented on the danger presented to farmers and consumers by the raw milk movement.

Key finding in stem cell self-renewal Posted: 06 Feb 2012 09:27 AM PST Scientists have proposed a mechanism for the control of whether embryonic stem cells continue to proliferate and stay stem cells, or differentiate into adult cells like brain, liver or skin. The work has implications in two areas. In cancer treatment, it is desirable to inhibit cell proliferation.

Strategy shift with age can lead to navigational difficulties Posted: 06 Feb 2012 06:26 AM PST A researcher believes studying people's ability to find their way around may help explain why loss of mental capacity occurs with age.

Children hospitalized at alarming rate due to abuse, U.S. study finds Posted: 06 Feb 2012 06:26 AM PST In one year alone, over 4,500 children in the United States were hospitalized due to child abuse, and 300 of them died of their injuries, researchers report in a new study.

Positive parenting during early childhood may prevent obesity Posted: 06 Feb 2012 06:25 AM PST Programs that support parents during their child's early years hold promise for obesity prevention, according to a new study.

Did your surgeons miss something? New system to prevent retained surgical items Posted: 06 Feb 2012 06:25 AM PST It may sound like something from a TV medical drama, but the incidence of surgeons leaving something behind in the body is very real at hospitals across the country. But researchers have now created a new system using state-of-the-art technologies to insure that no foreign objects are left behind during surgery.
