Rare Meteorite Found Using New Camera Network In Australian Desert Posted: 20 Sep 2009 02:00 PM PDT Researchers have discovered an unusual kind of meteorite in the Western Australian desert and have uncovered where in the Solar System it came from, in a very rare finding.

New Rabies Vaccine May Require Only A Single Shot, Not Six Posted: 20 Sep 2009 02:00 PM PDT A person, usually a child, dies of rabies every 20 minutes. However, only one inoculation may be all it takes for rabies vaccination, according to new research.

Uncertain Future Predicted For Forests Posted: 20 Sep 2009 02:00 PM PDT The composition of some of our nation's forests may be quite different 200 to 400 years from today according to a recent study. The study found that temperature and photosynthetic active radiation were the two most important variables in predicting what forest landscapes may look like in the future. The uncertainties became very high after the year 2200.

Medications Effective In Reducing Risks For Breast Cancer Can Also Cause Serious Side Effects Posted: 20 Sep 2009 02:00 PM PDT Three drugs that reduce a woman's chance of getting breast cancer also have been shown to cause adverse effects. This research is the first to make a direct, comprehensive comparison of drugs that reduce the risk of breast cancer so that women and their health-care providers can assess their potential effectiveness and adverse effects.

New X-ray Technique Illuminates Reactivity Of Environmental Contaminants Posted: 20 Sep 2009 02:00 PM PDT A chemical reaction can occur in the blink of an eye. Thanks to a new analytical method, scientists can now pinpoint, at the millisecond level, what happens as harmful environmental contaminants such as arsenic begin to react with soil and water under various conditions.

Researchers Explore Long-term Adolescent Vulnerability To Drugs Posted: 20 Sep 2009 02:00 PM PDT As part of efforts to understand drug abuse, researchers are finding that adolescent rats appear to be less vulnerable to the long-term effects of withdrawal and relapse in certain types of drug use than rats that take the drugs in adulthood.

Venus Express Adds Evidence For Atmospheric Water Loss On Earth's Twin Posted: 20 Sep 2009 08:00 AM PDT Observations by the European Space Agency's Venus Express mission have provided strong new evidence that the solar wind has stripped away significant quantities of water from Earth's twin planet. The data also shed new light on the transfer of trace gases in the Venusian atmosphere and wind patterns.

Nanoparticle-based Erectile Dysfunction Therapy Shows Promise Posted: 20 Sep 2009 08:00 AM PDT An innovative drug-delivery system -- nanoparticles encapsulating nitric oxide or prescription drugs -- shows promise for topical treatment of erectile dysfunction, according to a new study.

Impact Of Renewable Energy On Our Oceans Must Be Investigated, Say Scientists Posted: 20 Sep 2009 08:00 AM PDT Scientists are calling for urgent research to understand the impact of renewable energy developments on marine life. The study highlights potential environmental benefits and threats resulting from marine renewable energy, such as off-shore wind farms and wave and tidal energy conversion devices.

Cheap, Quick Bedside 'Eye Movement' Exam Outperforms MRI For Diagnosing Stroke In Patients Posted: 20 Sep 2009 08:00 AM PDT In a small "proof of principle" study, stroke researchers have found that a simple, one-minute eye movement exam performed at the bedside worked better than an MRI to distinguish new strokes from other less serious disorders in patients complaining of dizziness, nausea and spinning sensations.

Diamonds Are A Laser's Best Friend Posted: 20 Sep 2009 08:00 AM PDT Tomorrow's lasers may come with a bit of bling, thanks to a new technology that uses man-made diamonds to enhance the power and capabilities of lasers. Researchers have now demonstrated the first laser built with diamonds that has comparable efficiency to lasers built with other materials.

Doctors' 'Gut Feelings' Defined Posted: 20 Sep 2009 08:00 AM PDT "Gut feelings" experienced by general practitioners (GPs) play a substantial role in their diagnostic reasoning process, but always in combination with analytical reasoning. Gut feelings can be separated into the sense of alarm and the sense of reassurance. Researchers worked with 27 medical opinion leaders to closely define the concepts, which will allow future research to evaluate the effectiveness of this "gut-compass."

Planck Snaps Its First Images Of Ancient Cosmic Light Posted: 20 Sep 2009 02:00 AM PDT Planck, the European Space Agency's mission to study the early Universe, started surveying the sky regularly from its vantage point at L2 on August 13. The instruments of ESA's "time machine" were fine-tuned for optimum performance in the period preceding this date. In preparation for routine scientific operations, their long-term stability has been verified by conducting a first trial survey.

HIV Uses Several Strategies To Escape Immune Pressure Posted: 20 Sep 2009 02:00 AM PDT A study of how HIV mutates in response to immune system pressure shows that the virus can take several escape routes, not one preferred route.

Mechanism Related To Onset Of Various Genetic Diseases Revealed Posted: 20 Sep 2009 02:00 AM PDT Researchers in Spain have revealed the process by which proteins with a tendency to cause conformational diseases such as amyotrophic lateral sclerosis, familial amyloidotic polyneuropathy, familial amyloidotic cardiomyopathy, finally end up causing them. The researchers carried out an analysis of their 3D structure and studied why these proteins finally become toxic although they are correctly folded, an indicator that they are functioning correctly.

Protein Helps Distinguish Chromosome Ends From DNA Breaks Posted: 20 Sep 2009 02:00 AM PDT Researchers have demonstrated how human cells protect chromosome ends from misguided repairs that can lead to cancer. The work follows the team's 2007 in vitro demonstration of the role of the hRAP1 protein in preventing chromosome ends from being fused to new DNA breaks.

Controlling The Language Of Security: A New Language Could Improve Home Computer Security Posted: 20 Sep 2009 02:00 AM PDT Korean computer scientists have developed a security policy specification for home networks that could make us more secure from cyber attack in our homes.

Majority Of Unintended Incidents In The Emergency Room Are Caused By Human Error, Study Finds Posted: 20 Sep 2009 02:00 AM PDT Sixty percent of the causes of unintended incidents in the emergency department that could have compromised patient safety are related to human failures, according to a new study.
