Nanoscale DNA sequencing could spur revolution in personal health care (August 21, 2010) -- In experiments with potentially broad health care implications, researchers have devised a method that works at a very small scale to sequence DNA quickly and relatively inexpensively. That could open the door for more effective individualized medicine, for example providing blueprints of genetic predispositions for specific conditions and diseases such as cancer, diabetes or addiction. ... > full story
Virus may act as 'evolution-proof' biopesticide against malaria (August 21, 2010) -- A naturally occurring virus in mosquitoes may serve as a "late-life-acting" insecticide by killing older adult mosquitoes that are responsible for the bulk of malaria transmission. ... > full story
Big quakes more frequent than thought on San Andreas fault, research shows (August 21, 2010) -- Earthquakes have rocked the powerful San Andreas fault that splits California far more often than previously thought, according to researchers who have charted temblors there stretching back 700 years. ... > full story
Newly identified RNA sequence is key in microRNA processing (August 21, 2010) -- Researchers have uncovered a mechanism that regulates the processing of microRNAs (miRNAs), molecules that regulate cell growth, development, and stress response. The discovery helps researchers understand the links between miRNA expression and chronic disease. ... > full story
Lowering Daisy's emissions: Battle against agricultural climate offenders (August 21, 2010) -- Agriculture accounts for approximately nine per cent of Norway's total emissions of greenhouse gases. Now, researchers are acquiring actual gas measurements and new knowledge about what causes the emissions -- with the aim of mitigating Norwegian agriculture's impact on the climate and environment. In particular, it is emissions of the greenhouse gases methane (CH4, from cattle) and nitrous oxide (N2O, from the soil and fertilisers) that make agriculture such a major climate culprit. This summer Daisy has gone to pasture adorned with some advanced monitoring equipment to help out. ... > full story
Today's superheroes send wrong image to boys, say researchers (August 21, 2010) -- Watching superheroes beat up villains may not be the best image for boys to see if society wants to promote kinder, less stereotypical male behaviors, according to psychologists. ... > full story
Drought drives decade-long decline in plant growth (August 21, 2010) -- Global plant productivity that once was on the rise with warming temperatures and a lengthened growing season is now on the decline because of regional drought, according to a new study of NASA satellite data. ... > full story
Researchers identify two FDA approved drugs that may fight HIV (August 21, 2010) -- Researchers have identified two drugs that, when combined, may serve as an effective treatment for HIV. The two drugs, decitabine and gemcitabine -- both FDA approved and currently used in pre-cancer and cancer therapy -- were found to eliminate HIV infection in the mouse model by causing the virus to mutate itself to death -- an outcome researchers dubbed "lethal mutagenesis." ... > full story
New targets for anti-angiogenesis drugs revealed (August 21, 2010) -- A new study describes a novel pathway of angiogenesis, the growth of new blood vessels. Targeting the new pathway, scientists identified two approaches that significantly reduced angiogenesis in mice. These discoveries may lead to novel treatments for diseases caused by excessive angiogenesis, including corneal graft rejection, age-related macular degeneration, cancer and diabetes. ... > full story
Disturbances in certain genes play a role in autism (August 21, 2010) -- Autism researchers have found that autism can be partially explained by abnormalities in certain genes. The group's results could, in the long run, pave the way for more appropriate treatments for autism. ... > full story
Hydrogen causes metal to break (August 21, 2010) -- Hydrogen is considered the fuel of the future. Yet this lightest of the chemical elements can embrittle the metals used in vehicle engineering. The result: components suddenly malfunction and break. A new special laboratory is aiding researchers' search for hydrogen-compatible metals. ... > full story
Drug addicts get hooked via prescriptions, keep using 'to feel like a better person,' research shows (August 21, 2010) -- If you want to know how people become addicted and why they keep using drugs, ask the people who are addicted. Thirty-one of 75 patients hospitalized for opioid detoxification told physicians they first got hooked on drugs legitimately prescribed for pain. ... > full story
