Eureka! Neural evidence for sudden insight Posted: 14 May 2010 05:00 PM PDT A recent study provides intriguing information about the neural dynamics underlying behavioral changes associated with the development of new problem solving strategies. The research supports the idea of "a-ha" moments in the brain that are associated with sudden insight.

Cheese -- acting as 'carrier' for probiotic bacteria -- found to improve immune response of elderly Posted: 14 May 2010 05:00 PM PDT Scientists in Finland have discovered that cheese can help preserve and enhance the immune system of the elderly by acting as a carrier for probiotic bacteria. The research reveals that daily consumption of probiotic cheese helps to tackle age-related changes in the immune system.

Novel pouch could reduce mother-to-infant HIV infection Posted: 14 May 2010 05:00 PM PDT By using medications packaged just like fast-food ketchup, HIV-positive mothers in developing countries can more easily provide protection to newborn babies born at home.

Concerns over radiation exposure may overshadow life-saving benefits of cardiac imaging tests Posted: 14 May 2010 05:00 PM PDT When patients present with chest pain or other high-risk symptoms of heart problems, doctors increasingly rely on nuclear imaging and computed tomography (CT) tests to find out whether there is evidence of heart disease, blockages in the coronary arteries or reduced blood flow to the heart. Results of these procedures can help guide life-saving prevention and treatment options.

How microtubules let go of their attachments during cell division Posted: 14 May 2010 05:00 PM PDT Researchers have determined how cells regulate the chromosome/microtubule interface, which is central to proper chromosomal distribution during cell division. The chromosome/microtubule interface is critical during cell division. If a microtubule attaches incorrectly to a chromosome and cell division proceeds, the chromosomes may divide unevenly, resulting in cells with an incorrect number of chromosomes. Aberrant distribution of chromosomes can lead to cancer or premature cell death.

Going to the dogs: What can shy dogs teach us about longevity? Posted: 14 May 2010 05:00 PM PDT According to a new study by a Quebec research team, there are strong correlations between dog breeds' typical personalities, how long they live, and how much food they eat.

Black holes: Gas blowers of the universe Posted: 14 May 2010 02:00 PM PDT Supermassive black holes with the mass of many millions of stars have been detected at the centre of many large galaxies. A super-massive black hole acts like a lurking "monster" at the centre of the galaxy which swallows the surrounding material through the intensity of its gravitational pull. X-ray observations indicate that a large amount of energy is produced by the in-fall of matter into a black hole, and ejected in powerful jets. Astronomers have now shown that these jets eject matter not only from their host galaxies but even the gas between the galaxy group members.

Immune system compromised during spaceflight, study finds Posted: 14 May 2010 02:00 PM PDT Immunobiologists have discovered that spaceflight changes the activity of genes controlling immune and stress response, perhaps leading to more sickness.

Setting time limits for hunting and fishing may help maintain wildlife populations Posted: 14 May 2010 02:00 PM PDT Hunting and fishing quotas limit the number of game animals or fish an individual may take based on harvests from the previous year. But according to a new study, this strategy may jeopardize wildlife populations.

Researchers discover additional benefit of vitamin A Posted: 14 May 2010 02:00 PM PDT Vitamin A is critical to maternal health and child survival, yet in most developing countries Vitamin A deficiency is a leading cause of blindness and increased child mortality. Scientists recently discovered a link between offspring lung function and maternal vitamin A supplementation.

Emergence of fungal plant diseases linked to ecological speciation Posted: 14 May 2010 02:00 PM PDT A new commentary on the nature of pathogens is raising startling new questions about the role that fundamental science research on evolution plays in the understanding of emerging disease.

Childhood psychological problems create long-term economic losses, study finds Posted: 14 May 2010 02:00 PM PDT A first-of-its-kind study examining the long-term economic consequences of childhood psychological disorders such as depression and substance abuse finds the conditions diminish people's ability to work and earn as adults, costing $2.1 trillion over the lifetimes of all affected Americans.

Quality of child care linked to academic achievement: Behaviors persist into adolescence Posted: 13 May 2010 09:00 PM PDT Teens who were in high-quality child care settings as young children scored slightly higher on measures of academic and cognitive achievement and were slightly less likely to report acting-out behaviors than peers who were in lower-quality child care arrangements during their early years, according to the latest analysis of a long-running study.

Muscle mass in elderly boosted by combining resistance exercise and blood flow restriction Posted: 13 May 2010 09:00 PM PDT Researchers have determined that moderately and temporarily restricting the flow of blood through muscles -- a practice adopted by bodybuilders who noticed that it made light weights feel heavier -- can be combined with low-level resistance exercise training to produce muscle-mass increases in older men.

Homeless adults have significant unmet health care needs, study finds Posted: 13 May 2010 09:00 PM PDT The vast majority of homeless adults surveyed in a national study had trouble accessing at least one type of needed health care service in the preceding year, according to new research that may be the first broad-based national study of factors related to unmet health needs among homeless people.

The fear of falling Posted: 13 May 2010 09:00 PM PDT One in four people over the age of 70 suffers from gait disturbance. To prevent falls, specific treatment should be given. In a new study, researchers in Germany describe methods of differential diagnosis and therapy.

Lowering pH regulates spider’s silk production, researchers find Posted: 13 May 2010 09:00 PM PDT How can a tiny spider body contain material for several decimeters of gossamer silk, and what governs the conversion to thread? Researchers in Sweden can now explain this process.

Growers can boost benefits of broccoli and tomatoes Posted: 13 May 2010 09:00 PM PDT Agronomic practices can greatly increase the cancer-preventive phytochemicals in broccoli and tomatoes. The highest levels of detoxifying enzymes were found in rats that ate selenium-treated broccoli.
