Hidden Diversity In Key Environmental Cleanup Microbes Found By Systems Biology Assessment Posted: 05 Oct 2009 08:00 AM PDT Researchers analyzed the gene sequences, proteins expressed and physiology of 10 strains of bioremediation microbes called Shewanella. Results showed surprising diversity not seen using traditional microbiology approaches.

Tai Chi May Be An Effective Treatment For Dizziness, Balance Issues Posted: 05 Oct 2009 08:00 AM PDT Tai Chi, a form of Chinese martial arts often practiced for its health benefits, may be an effective treatment option for patients who suffer from dizziness and balance disorders (also known as vestibular disorders).

Graphite Mimics Iron's Magnetism: New Nanotech Applications Posted: 05 Oct 2009 05:00 AM PDT Researchers show for the first time why ordinary graphite is a permanent magnet at room temperature. The results are promising for new applications in nanotechnology, such as sensors and detectors. In particular graphite could be a promising candidate for a biosensor material.

Global Death Toll: One Million Premature Babies Every Year Posted: 05 Oct 2009 05:00 AM PDT Some 13 million babies worldwide were born preterm and more than one million die annually as a result, according to the the March of Dimes. The highest preterm birth rates are in Africa, followed by North America (United States and Canada).

Microbiology: Free-for-all On The Leaf Surface Posted: 05 Oct 2009 05:00 AM PDT Scientists have examined the genes and proteins of bacteria that live on leaves to clarify which unicellular organisms are found on leaf surfaces and what they are doing there.

Radiofrequency Energy Technique As Effective As Tonsillectomy Surgery, Study Finds Posted: 05 Oct 2009 05:00 AM PDT Radiofrequency tonsillotomy, which enables surgeons to reduce the size of the tonsillar tissue instead of removing the tonsils entirely, seems to be an effective and safe method of treating children with symptoms of enlarged tonsils.

Femtoseconds Lasers Help Formation Flying In Space Posted: 05 Oct 2009 05:00 AM PDT The National Physical Laboratory has helped to establish that femtosecond comb lasers can provide accurate measurement of absolute distance in formation flying space missions.

Brazilians, North Americans Judge Facial Beauty Differently Posted: 05 Oct 2009 05:00 AM PDT Standard ideals of facial beauty and harmony may differ depending on geographic location, with a specific difference between North American beauty ideals and those of Brazilians.

Gene Controlling Number Of Brain Cells Pinpointed Posted: 05 Oct 2009 02:00 AM PDT A new study suggests that a single gene, called GSK-3, controls the signals that determine how many neurons actually end up composing the brain. This has important implications for patients with neuropsychiatric illness, as links have recently been drawn between GSK-3 and schizophrenia, depression and bipolar disorder.

'Micro Shuttle' Drug Delivery Could Mean An End To Regular Dosing Posted: 05 Oct 2009 02:00 AM PDT Scientists have developed micrometer-sized capsules to safely deliver drugs inside living cells. In the future, this technique could allow full courses of prescription drugs to be effectively "shrink-wrapped" and buried under the skin or inside the body.

There's Still Time To Cut The Risk Of Climate Catastrophe, Study Shows Posted: 05 Oct 2009 02:00 AM PDT A new analysis of climate risk shows that even moderate carbon-reduction policies now can substantially lower the risk of future climate change. It also shows that quick, global emissions reductions would be required in order to provide a good chance of avoiding a temperature increase of more than 2 degrees Celsius above the pre-industrial level -- a widely discussed target.

Scientists Determine Dynamics Of HIV Transmission In UK Heterosexuals Posted: 05 Oct 2009 02:00 AM PDT Among heterosexuals in the United Kingdom, HIV transmission can occur within networks of as many as 30 people, according to a new study.
