New Class Of Dim Supernovae Posted: 07 Jun 2009 02:00 PM PDT The colossal stellar explosions called supernovae come in many kinds and flavors. Some of them are produced when a massive star reaches the end of its life in a sudden gravitational collapse. Astronomers have just found one of these explosions that defies the current classification scheme.

New Way To Enhance Stem Cells To Stimulate Muscle Regeneration Posted: 07 Jun 2009 02:00 PM PDT Scientists have discovered a powerful new way to stimulate muscle regeneration, paving the way for new treatments for debilitating conditions such as muscular dystrophy. The research shows for the first time that a protein called Wnt7a increases the number of stem cells in muscle tissue, leading to accelerated growth and repair of skeletal muscle.

Key Regulator Of Fat Cell Development Discovered Posted: 07 Jun 2009 02:00 PM PDT Scientists have discovered how two related proteins and their roles in a key molecular pathway are critical to creating obesity-causing fat cells.

Findings In Epilepsy Gene In Animals May Guide Treatment Directions For Infants Posted: 07 Jun 2009 02:00 PM PDT Researchers studying a difficult-to-treat form of childhood epilepsy called infantile spasms have developed a line of mice that experiences seizures with features closely resembling those occurring in human infants. These genetically engineered mice provide a new opportunity for scientists to test treatments that may benefit children.

Surprising Green Energy Investment Trends Found Worldwide Posted: 07 Jun 2009 02:00 PM PDT Some $155 billion was invested in 2008 in clean energy companies and projects worldwide, not including large hydro, a new report says. Of this $13.5 billion of new private investment went into companies developing and scaling-up new technologies alongside $117 billion of investment in renewable energy projects from geothermal and wind to solar and biofuels.

Gay Marriage Bans Linked To Rise In HIV Rate Posted: 07 Jun 2009 02:00 PM PDT Bans on same-sex marriage can be tied to a rise in the rate of HIV infection, a new study has found.

'Colossal' Magnetic Effect Under Pressure: Another Revolution In Computing Technology? Posted: 07 Jun 2009 08:00 AM PDT Millions of people today carry around pocket-sized music players capable of holding thousands of songs, thanks to the discovery 20 years ago of a phenomenon known as the "giant magnetoresistance effect," which made it possible to pack more data onto smaller and smaller hard drives. Now scientists are on the trail of another phenomenon, called the "colossal magnetoresistance effect" (CMR) which is up to a thousand times more powerful and could trigger another revolution in computing technology.

New Genetic Immune Disorder In Children Discovered Posted: 07 Jun 2009 08:00 AM PDT Your immune system plays an important function in your health -- it protects you against viruses, bacteria, and other toxins that can cause disease. In autoinflammatory diseases, however, the immune system goes awry, causing unprovoked and dangerous inflammation. Now, researchers have discovered a new autoinflammatory syndrome, a rare genetic condition that affects children around the time of birth.

Nature Parks Can Save Species As Climate Changes Posted: 07 Jun 2009 08:00 AM PDT Retaining a network of wildlife conservation areas is vital in helping to save up to 90 per cent of bird species in Africa affected by climate change, according to scientists.

Linking Genetic Material MicroRNAs With Cells That Regulate The Immune System Could One Day Lead To New Therapies For Treating Cancer Posted: 07 Jun 2009 08:00 AM PDT Linking genetic material microRNAs with cells that regulate the immune system could one day lead to new therapies for treating cancer, infections and autoimmune diseases, according to a new study.

New Technique Developed To Evaluate Basketball Players Posted: 07 Jun 2009 08:00 AM PDT A team of Spanish and American researchers has developed a method to evaluate basketball players that will, they say, better meet the requirements of the sport's trainers and experts. The technique uses mathematical models designed to measure productivity.

Crowded Emergency Departments Pose Greater Risks For Patients With Heart Attacks Posted: 07 Jun 2009 08:00 AM PDT Patients with heart attacks and other forms of chest pain are three to five times more likely to experience serious complications after hospital admission when they are treated in a crowded emergency department, according to a new study.

Geography And History Shape Genetic Differences In Humans Posted: 07 Jun 2009 02:00 AM PDT New research indicates that natural selection may shape the human genome much more slowly than previously thought. Other factors -- the movements of humans within and among continents, the expansions and contractions of populations, and the vagaries of genetic chance -- have heavily influenced the distribution of genetic variations in populations around the world.

Gene For Deadly Inherited Lung Disease Identified Posted: 07 Jun 2009 02:00 AM PDT A rare, deadly developmental disorder of the lungs called alveolar capillary dysplasia with misalignment of pulmonary veins (ACD/MPV) that usually kills the infants born with it within the first month of life results from deletions or mutations in the FOXF1 transcription factor gene, said a consortium of researchers.

Breast Cancer Gene Can Be Blocked By Blood Pressure Drug Posted: 07 Jun 2009 02:00 AM PDT Researchers have identified a gene that is overexpressed in up to 20 percent of breast cancers and that could be blocked in the lab by a currently available blood pressure drug, according to a new study.

Break From Hormone Therapy Doesn't Improve Mammograms Posted: 07 Jun 2009 02:00 AM PDT It's the downside of not needing to wear a bra: Having "dense" breasts is the biggest risk factor for breast cancer, aside from age. Postmenopausal hormone therapy makes breasts denser -- and harder to "read" on mammograms. So some women take a short hormone break before getting screening mammograms. Now the first large-scale randomized controlled trial of this practice shows it doesn't actually lower women's risk of being called back afterward for unnecessary extra breast imaging.

Breakthrough Toward Industrial Production Of Fluorescent Nanodiamonds Posted: 07 Jun 2009 02:00 AM PDT Scientists have discovered a novel route to fabricate fluorescent nanoparticles from diamond microcrystals.

Smoking-cessation Research Highlights Importance Of Keeping Teens From Smoking Posted: 07 Jun 2009 02:00 AM PDT Despite the efforts of college students to quit smoking, recent research suggests that an extended trial and error period is necessary. Given that most college students begin smoking in high school, another study provides insights into how graphic cigarette warning labels impact intentions of American and Canadian teens.

Bird Species Decline: Wader Populations Decline Faster Than Ever Posted: 05 Jun 2009 09:00 PM PDT More than half the populations of waders in Europe, West Asia and Africa are declining at an accelerating rate.

Bird Migrations Set To Increase: Added Distance Is 'Considerable Threat' To Some Species Posted: 05 Jun 2009 09:00 PM PDT Bird migrations are likely to get longer according to the first ever study of the potential impacts of climate change on the breeding and winter ranges of migrant birds. The length of some migrations could increase by as much as 400 km. "The predicted future temperature changes and the associated changes in habitat could have serious consequences for many species", said lead-author of a new study.

Hundreds Of Cell-surface Proteins Can Be Simultaneously Studied With New Technique Posted: 05 Jun 2009 09:00 PM PDT A new method now enables researchers to study hundreds of cell-surface proteins simultaneously. The results obtained could help to develop more accurate diagnostic tests and more specific therapies in the future.

Beehive Fence Deters Elephant Raiders Posted: 05 Jun 2009 09:00 PM PDT A fence made out of beehives wired together has been shown to significantly reduce crop raids by elephants, Oxford University scientists report.

Misreading Of Histone Code Linked To Human Cancer Posted: 05 Jun 2009 09:00 PM PDT The development of blood from stem cell to fully formed blood cell follows a genetically determined program. When it works properly, blood formation stops when it reaches maturity. But when it doesn't, genetic mutations can prevent the stop signal and cause the developing cells to turn cancerous. In research published in Nature, Rockefeller University scientists show for the first time that a misreading of the blood cells' histone code is responsible for acute myeloid leukemia, a rare form of the deadly blood cancer.

Unmanned Aircraft Helping Scientists Learn About Alaskan Ice Seals Posted: 05 Jun 2009 09:00 PM PDT Scientists have launched an unmanned aircraft to mount the vehicle's first search for ice seals at the southern edge of the Bering Sea pack ice during the Arctic spring, in an effort to learn more about these remotely located species.

New Category Of Fat In Mammalian Cells May Help Explain How Toxin Harms Farm Animals Posted: 05 Jun 2009 09:00 PM PDT A new category of fats in mammalian cells may help explain how a harmful toxin called fumonisin causes disease in farm animals.

'Junk' DNA Proves To Be Highly Valuable Posted: 05 Jun 2009 09:00 PM PDT What was once thought of as DNA with zero value in plants--dubbed "junk" DNA--may turn out to be key in helping scientists improve the control of gene expression in transgenic crops.
