Marine scientists urge government to reassess oil spill response Posted: 20 Apr 2012 09:39 AM PDT On the second anniversary of the Deepwater Horizon blowout, a national panel of researchers is urging the US federal government to reassess how it would respond to similar oil spills that might occur in the future.

How 'checkpoint' proteins bind chromosomes Posted: 20 Apr 2012 09:38 AM PDT New research has pinpointed the precise mechanism by which spindle checkpoint proteins bind chromosomes. The development of more effective cancer drugs could now be a step nearer.

Soda consumption increases overall stroke risk Posted: 20 Apr 2012 09:38 AM PDT Researchers have found that greater consumption of sugar-sweetened and low-calorie sodas is associated with a higher risk of stroke. Conversely, consumption of caffeinated or decaffeinated coffee was associated with a lower risk.

Early treatment improves outcomes in rare, often undiagnosed form of encephalitis Posted: 20 Apr 2012 09:38 AM PDT A mysterious, difficult-to-diagnose, and potentially deadly disease that was only recently discovered can be controlled most effectively if treatment is started within the first month that symptoms occur, according to a new report.

New genes contributing to autism and related neurodevelopmental disorders uncovered Posted: 20 Apr 2012 09:38 AM PDT Researchers have utilized new sequencing strategies to reveal chromosome abnormalities associated with autism and other neurodevelopmental disorders.

Your left side is your best side: Our left cheek shows more emotion, which observers find more aesthetically pleasing Posted: 20 Apr 2012 09:38 AM PDT Your best side may be your left cheek, according to a new study. Images of the left side of the face are perceived and rated as more pleasant than pictures of the right side of the face, possibly due to the fact that we present a greater intensity of emotion on the left side of our face.

Human neural stem cells with tumor targeting ability discovered Posted: 20 Apr 2012 08:00 AM PDT Could engineered human stem cells hold the key to cancer survival? Scientists have discovered that neural stem cells possess the innate ability to target tumor cells outside the central nervous system. This finding was demonstrated successfully on breast cancer cells.

New stem cell found in brain: Finding could be key to developing methods to heal and repair brain injury and disease Posted: 20 Apr 2012 07:59 AM PDT Researchers have discovered a new stem cell in the adult brain. These cells can proliferate and form several different cell types -- most importantly, they can form new brain cells. Scientists hope to take advantage of the finding to develop methods to heal and repair disease and injury in the brain.

Scientists find Achilles' heel in life-threatening malaria parasites Posted: 20 Apr 2012 07:58 AM PDT Scientists have identified a link between different strains of malaria parasites that cause severe disease, which could help develop vaccines or drugs against life-threatening cases of the infection.

Meat eating behind evolutionary success of humankind, global population spread, study suggests Posted: 20 Apr 2012 07:55 AM PDT Carnivory is behind the evolutionary success of humankind. When early humans started to eat meat and eventually hunt, their new, higher-quality diet meant that women could wean their children earlier. Women could then give birth to more children during their reproductive life, which is a possible contribution to the population gradually spreading over the world. The connection between eating meat and a faster weaning process is shown by a research group from Sweden, which compared close to 70 mammalian species and found clear patterns.

Freeing loggerhead turtles comes at a price Posted: 20 Apr 2012 07:53 AM PDT Scientists have studied loggerhead turtles' re-adaptation to the environment. The results show that after a lengthy recovery in rehabilitation centers these animals display changes in behavior and may not adapt well to being free.

Polar bears evolutionarily five times older and genetically more distinct: Ancestry traced back 600,000 years Posted: 20 Apr 2012 07:53 AM PDT Polar bears evolved as early as some 600,000 years ago, according to a new study. Scientists show the largest arctic carnivore to be five times older than previously thought. The new findings on the evolutionary history of polar bears are the result of an analysis of information from the nuclear genome of polar and brown bears, and shed new light on conservation issues regarding this endangered arctic specialist.

Body cooling cuts in-hospital cardiac arrest patient deaths nearly 12 percent Posted: 20 Apr 2012 07:53 AM PDT Forced body cooling known as therapeutic hypothermia has reduced in-hospital deaths among sudden cardiac arrest patients nearly 12 percent between 2001 and 2009, according to a new study.

Alzheimer's plaques disrupt brain networks Posted: 20 Apr 2012 07:45 AM PDT Researchers have shown that brain plaques in mice are associated with disruption of the ability of brain regions to network with each other.

Parent diet choice knowledge doesn't prevent child obesity Posted: 20 Apr 2012 07:45 AM PDT A study of the families of 150 preschoolers suggests that parents of healthy-weight and overweight preschoolers are generally well aware of dietary risk factors that fuel childhood obesity.

Dawn gets extra time to explore Vesta Posted: 20 Apr 2012 06:43 AM PDT NASA's Dawn mission has received official confirmation that 40 extra days have been added to its exploration of the giant asteroid Vesta, the second most massive object in the main asteroid belt. The mission extension allows Dawn to continue its scientific observations at Vesta until Aug. 26, while still arriving at the dwarf planet Ceres at the same originally scheduled target date in February 2015.

Cassini finds Titan lake is like a Namibia mudflat Posted: 20 Apr 2012 06:40 AM PDT A new study analyzing data from NASA's Cassini spacecraft suggests that the lake, known as Ontario Lacus, behaves most similarly to what we call a salt pan on Earth.

NASA image gallery highlights Earth's changing face Posted: 20 Apr 2012 06:20 AM PDT In celebration of this year's Earth Day on April 22, NASA's Global Climate Change website has unveiled a new version of its popular image gallery, "State of Flux." The gallery presents stunning images, mostly from space, of our ever-changing planet, chronicling changes taking place over time periods ranging from days to centuries.

Warning signs from ancient Greek tsunami Posted: 19 Apr 2012 12:39 PM PDT In the winter of 479 B.C., a tsunami was the savior of Potidaea, drowning hundreds of Persian invaders as they lay siege to the ancient Greek village. New geological evidence suggests that the region may still be vulnerable to tsunami events.

Online chatter affects stock returns Posted: 19 Apr 2012 12:38 PM PDT It turns out that all of those bad reviews of new computers, shoes, toys and other products at Amazon and other websites with consumer reviews have more impact than just helping shoppers decide if they'll buy the newest smartphone. Negative web buzz can drive down stock prices.

Accelerating climate change exerts strong pressure on Europe's mountain flora Posted: 19 Apr 2012 11:31 AM PDT Mountain plants across the continent are moving to higher altitudes. The new article is based on detailed surveys of 66 mountain summits in Europe. Scientists mapped all plant species at each European site in 2001 and 2008.

New study links air pollution and early death in the UK Posted: 19 Apr 2012 10:26 AM PDT Emissions from cars, trucks, planes and power plants cause 13,000 premature deaths in the United Kingdom each year, new research suggests.

New genes discovered contributing to autism, links to psychiatric disorders Posted: 19 Apr 2012 09:15 AM PDT A new approach to investigating hard-to-find chromosomal abnormalities has identified 33 genes associated with autism and related disorders, 22 for the first time. Several of these genes also appear to be altered in different ways in individuals with psychiatric disorders such as schizophrenia.

Childhood trauma linked to schizophrenia Posted: 19 Apr 2012 07:24 AM PDT Researchers have found that children who have experienced severe trauma are three times as likely to develop schizophrenia in later life.
