Hundreds Of New Species Discovered In Eastern Himalayas Posted: 11 Aug 2009 05:00 AM PDT Over 350 new species including the world's smallest deer, a "flying frog" and a 100-million-year old gecko have been discovered in the Eastern Himalayas, a biological treasure trove now threatened by climate change. A decade of research carried out by scientists in remote mountain areas endangered by rising global temperatures brought exciting discoveries such as a bright green frog that uses its red and long webbed feet to glide in the air.

Found: A Gene That May Play A Role In Type 1 Diabetes Posted: 11 Aug 2009 05:00 AM PDT Scientists have identified a gene that may play a role in the development of type 1 diabetes, an autoimmune disease in which the immune system attacks the body's insulin-producing cells. Insulin, a hormone produced by cells of the pancreas, helps the body to absorb sugars found in food and to maintain blood sugar at appropriate levels.

Triple Asteroid System Triples Observers' Interest Posted: 11 Aug 2009 05:00 AM PDT Radar imaging at NASA's Goldstone Solar System Radar on June 12 and 14, 2009, revealed that near-Earth asteroid 1994 CC is a triple system. Asteroid 1994 CC encountered Earth within 2.52 million kilometers (1.56 million miles) on June 10. Prior to the flyby, very little was known about this celestial body.

Low Prevalence Of HPV Infection May Be Tied To Poor Prognosis For Blacks With Head And Neck Cancer Posted: 11 Aug 2009 05:00 AM PDT Researchers at the University of Maryland Marlene and Stewart Greenebaum Cancer have found that head and neck cancer patients who test positive for the human papillomavirus (HPV) have much better survival rates than patients who don't have the virus, according to a new study in the journal Cancer Prevention Research. The researchers also discovered that blacks in the study had a very low rate of HPV infection, and consequently worse survival.

Navigating In The Ocean Of Molecules: Computer Program Points The Way To New Disease Treatments Posted: 11 Aug 2009 05:00 AM PDT Tracking down new active agents for cancer or malaria treatment could soon become easier. A new computer program acts as a tool for navigating chemical space. It generates maps of chemically-related structures and links them to biological activity, that is, to their potential to bind to proteins, in particular medically relevant proteins.

Smoking, Binge Drinking: Double-threat To Teen Health Posted: 11 Aug 2009 05:00 AM PDT Researchers have found that teens who are smokers are also more likely to binge drink. They say both these behaviors need to be addressed together as one health risk.

Meteorite Found On Mars Yields Clues About Planet's Past Posted: 11 Aug 2009 02:00 AM PDT NASA's Mars Rover Opportunity is investigating a metallic meteorite the size of a large watermelon that is providing researchers more details about the Red Planet's environmental history. The rock, dubbed "Block Island," is larger than any other known meteorite on Mars.

Resistance To Antibiotics: When 1+1 Is Not 2- Genetic Interactions Underlie Multi-resistant Bacteria Posted: 11 Aug 2009 02:00 AM PDT The evolution of multiple antibiotic resistances is a global and difficult problem to eradicate. Scientists report that the deleterious effect associated with the acquisition of resistance by a bacteria can be suppressed by the acquisition of a new resistance to another antibiotic. These findings have direct implications for the approaches taken to tackle the problem of multi-resistance to antibiotics and in the choice of antibiotics to be administrated to patients.

Ocean Health Plays Vital Role In Coral Reef Recovery Posted: 11 Aug 2009 02:00 AM PDT A new study shows that bleached corals bounce back to normal growth rates more quickly when they have clean water and plentiful sea life at their side.

Prehypertension, Obesity And Kidney Disease Risks Posted: 11 Aug 2009 02:00 AM PDT People with prehypertension are not at increased risk of kidney disease if their body mass index (BMI) is under 30.0 kg/m2, a first-ever examination of the combined effect of blood pressure and body weight on the risk of kidney disease shows.

Understanding How Weeds Are Resistant To Herbicides Posted: 11 Aug 2009 02:00 AM PDT In a little over seven hours, one weed scientist got more genetic information about waterhemp than in two years time in a lab. The genetic information was obtained using pyrosequencing technology. The genetic sequence will allow scientists to study herbicide resistance in waterhemp.

Parents Fear Errors During Children's Hospitalization Posted: 11 Aug 2009 02:00 AM PDT Nearly two-thirds of parents reported they felt the need to watch over their child's care to ensure that medical errors are not made during their hospital stay, according to a new study. Parents whose first language is not English were more likely to report the need to be vigilant about their child's care.

Humans 'Damaging The Oceans' In Profound Ways Posted: 10 Aug 2009 11:00 PM PDT There is mounting evidence that human activity is changing the world's oceans in profound and damaging ways. Man-made carbon emissions "are affecting marine biological processes from genes to ecosystems over scales from rock pools to ocean basins, impacting ecosystem services and threatening human food security," warn experts.

Advanced Targeted Therapies Effective As First-line Treatment For Lung Cancer Posted: 10 Aug 2009 11:00 PM PDT Several new studies show that targeted therapies, as first-line treatment, have the potential to slow cancer growth and improve patient outcomes.

Woodlands Suffer Large-scale Biodiversity Loss Posted: 10 Aug 2009 11:00 PM PDT 21st century British woodlands are less distinctive than those of the early 20th century due to environmental change. Native woodland plants have re-organized over the last 70 years in response to increased soil fertility and loss of light related to increased canopy shading.

Physician Trust, Early Screening Reduces Disparities For Prostate Cancer Posted: 10 Aug 2009 11:00 PM PDT Men who have a regular, ongoing relationship with a health-care provider are more likely to receive prostate cancer screening and less likely to be diagnosed with advanced prostate cancer, regardless of their race, according to a new study.

New Computer Simulation Helps Explain Folding In Important Cellular Protein Posted: 10 Aug 2009 11:00 PM PDT Scientists have created a two-step computer simulation (using an important process called the Wang-Landau algorithm) that sheds light on how a crucial protein -- glycophorin A -- becomes an active part of living cells. The new use of Wang-Landau could lead to a better understanding of the controlling mechanisms behind protein folding.

Northern Ireland: One In Ten 16 Year Olds Have Self-harmed In Past Year Posted: 10 Aug 2009 11:00 PM PDT One in ten 16 year olds in Northern Ireland have self-harmed in the past year, according to new research. Of the 941 young people who were questioned during the 2008 Young Life and Times Survey, a further 14 per cent had thought about harming themselves in the past year but had not done so. This is the first time a representative sample of young people in Northern Ireland has been asked about their attitudes to and experiences of self-harm.

Physicians Bust Myths About Insulin Posted: 10 Aug 2009 09:00 PM PDT People diagnosed with type 2 diabetes often resist taking insulin because they fear gaining weight, developing low blood sugar and seeing their quality of life decline. A study suggests that those fears are largely unfounded and that patients and physicians should consider insulin as a front-line defense, as opposed to a treatment of last resort for non-insulin-dependent diabetes.
