Rating Attractiveness: Consensus Among Men, Not Women, Study Finds Posted: 27 Jun 2009 02:00 PM PDT Hot or not? Men agree on the answer. Women don't. There is much more consensus among men about whom they find attractive than there is among women, according to a new study.

Evidence Of Memory Seen In Songbird Brain Posted: 27 Jun 2009 08:00 AM PDT When a zebra finch hears a new song from a member of its own species, the experience changes gene expression in its brain in unexpected ways, researchers report. The sequential switching on and off of thousands of genes after a bird hears a new tune offers a new picture of memory in the songbird brain.

Trial Shows Promise For Arthritis Drug Posted: 27 Jun 2009 08:00 AM PDT A clinical trial of masitinib, a drug in development for the treatment of rheumatoid arthritis, has shown it to be well-tolerated and effective. Researchers have shown that treatment with masitinib significantly reduced the severity of active arthritis.

Scientists Identify Key Factor That Controls HIV Latency Posted: 27 Jun 2009 08:00 AM PDT Scientists have found another clue that may lead to eradication of HIV from infected patients who have been on antiretroviral therapy. A real cure for HIV has been elusive because the virus can "hide" in a latent form in resting CD4-T cells. By understanding this "latency" effect, researchers can identify ways to reactivate the virus, and enable complete clearance by current or future therapies.

Engineers Investigate Lead-Free Soldering Posted: 27 Jun 2009 08:00 AM PDT Engineers aim to improve the reliability of lead-free soldering alloys that are used to make electronic devices. This would help with the implementation of environmentally-friendly materials in electronics production.

One In 25 Deaths Worldwide Attributable To Alcohol Posted: 27 Jun 2009 08:00 AM PDT Worldwide, one in 25 deaths are directly attributable to alcohol consumption. This rise since 2000 is mainly due to increases in the number of women drinking.

How High Carbohydrate Foods Can Raise Risk For Heart Problems Posted: 27 Jun 2009 02:00 AM PDT Doctors have known for decades that too much carbohydrate-laden foods like white bread and corn flakes can be detrimental to cardiac health. In a landmark study, new research now shows exactly how these high-carb foods increase the risk for heart problems.

STAT3 Protein Found To Play A Key Role In Cancer Posted: 27 Jun 2009 02:00 AM PDT A protein called STAT3 has been found to play a fundamental role in converting normal cells to cancerous cells, according to a new study. The study found that STAT3, in addition to its role in the cell nucleus regulating gene expression, is also present in mitochondria, and regulates the activity of the electron transport chain in tumors cells.

Corals Stay Close to Home Posted: 27 Jun 2009 02:00 AM PDT New DNA analysis reveals that corals in one locality are more closely related than previously thought; results have significant implications for coral conservation.

Study Challenges Routine Use Of MRI Scans To Evaluate Breast Cancer Posted: 27 Jun 2009 02:00 AM PDT Reviewing the records of 577 breast cancer patients, researchers found that women with newly diagnosed breast cancer who receive a breast MRI are more likely to receive a mastectomy after their diagnosis and may face delays in starting treatment. The study demonstrates that, despite the lack of evidence of their benefit, routine use of MRI scans in women newly diagnosed with breast cancer increased significantly between 2004 and 2005, and again in 2006.

Electronic Help For Caregivers Monitoring Patients' Health And Whereabouts Posted: 27 Jun 2009 02:00 AM PDT For those who are caring for elderly parents, peace of mind is hard to come by. And, for their parents, dignity is hard to retain. But researchers hopes to ease worries and frustrations by designing an affordable in-home health-monitoring system that will notify caregivers, via smartphones or PDAs, if their loved ones need attention.

Diabetes Is Significant Economic Burden For US Health-care System Posted: 27 Jun 2009 02:00 AM PDT Excess medical expenses and reduced productivity due to diabetes costs the US economy more than $174 billion annually, a figure that could be reduced by lifestyle modifications and preventive care and by pay-for-performance incentives that reward improved disease management.

'Neurologger' Reads Bird Brains In Flight Posted: 26 Jun 2009 05:00 PM PDT Using a "neurologger" specially designed to record the brain activity of pigeons in flight, researchers have gained new insight into what goes through the birds' minds as they fly over familiar terrain. The study is the first to simultaneously record electrical brain activity integrated with large-scale navigational movements of free-flying birds, according to the researchers.

Broad Therapy For Muscular Dystrophy Posted: 26 Jun 2009 05:00 PM PDT Scientists have demonstrated that the glycosyltransferase Galgt2 can lessen symptoms in multiple models of muscular dystrophy. Muscular dystrophy is a group of inherited muscular disorders that are characterized by progressive skeletal muscle weakness, defects in muscle proteins, and the death of muscle cells and tissue.

Best Possible Cut From Gemstones With New Machine Posted: 26 Jun 2009 05:00 PM PDT Emeralds, rubies and the likes are referred to as colored gemstones by experts. They sparkle and shine with varying intensity, depending on the cut. A new machine can achieve the best possible cut and extract up to 30 per cent more precious stone from the raw material.
