Volcano discovered smoldering under a kilometer of ice in West Antarctica
A temporary seismic array in Marie Byrd Land in West Antarctica recorded two bursts of activity in 2010 and 2011. Careful analysis of the events shows they originate from a subglacial volcano at the leading end of a volcanic mountain chain. The volcano is unlikely to erupt through the kilometer of ice that covers it but it will melt enough ice to change the way the ice in its vicinity flows.

Preschoolers exposure to television can stall their cognitive development
Television is a powerful agent of development for children, particularly those in preschool. But when could too much TV be detrimental to a young child's mind? A recent paper published in the Journal of Communication found that preschoolers who have a TV in their bedroom and are exposed to more background TV have a weaker understanding of other people's beliefs and desires.

Obesity and nutrition are keys to avoiding metabolic syndrome
Data reported by the Hearts Beat Back: The Heart of New Ulm Project reinforce the positive influence of lifestyle factors in mitigating risks that potentially increase the likelihood of heart disease and other health problems. Findings based on 1,059 residents of New Ulm, Minn., underscore the importance of obesity prevention and nutrition, specifically eating more fruits and vegetables, in addressing metabolic syndrome, a common precursor to cardiovascular disease.

FDA approved immune-modulating drug unexpectedly benefits mice with fatal mitochondrial defect
In a lab devoted to increasing healthy lifespans, the transplant anti-rejection drug rapamycin showed unexpected health benefits and increased survival in a mouse model of a fatal mitochondrial defect. Children with the untreatable condition suffer from brain damage and muscle weakness, and rarely live beyond 6 or 7 years. The drug enables the body to bypass the mitochondrial defect by switching its metabolism to burn fats and amino acids instead of glucose, and thereby reduces toxic byproducts.

Pre-industrial rise in greenhouse gases had natural and anthropogenic causes
For years scientists have intensely argued over whether increases of potent methane gas concentrations in the atmosphere -- from about 5,000 years ago to the start of the industrial revolution -- were triggered by natural causes or human activities. A new study, published Friday in the journal Science, suggests the increase in methane likely was caused by both.

The reality behind Europe's response to climate change
British cities -- unlike their counterparts on the mainland -- are taking the lead in making plans to curb and handle the impact of climate change. A study in Climatic Change analyzed the relevant strategic policies and planning documents of 200 urban areas in eleven European countries. It found that one in every three European cities has no plans to reduce greenhouse gas emissions, while seven in every ten urban areas have no formal adaptation plans.

Brain imaging differences in infants at genetic risk for Alzheimer's
Researchers at Brown University and Banner Alzheimer's Institute have found that infants who carry a gene associated with an increased risk for Alzheimer's disease tend to have differences in brain development compared to infants who do not carry the gene. The findings do not mean that these infants will get Alzheimer's, but they may be a step toward understanding how this gene confers risk much later in life.

It's like a party in the atmosphere!
The Space Test Program-Houston 4-FireStation investigation, also simply known as FireStation, will orbit the Earth for a year attached to the outside of the space station. This instrument collects data as it flies over thunderstorms, taking aim at the exciting energy exhibit to help scientists answer burning questions involving the relationship between lightning and gamma rays.

Hands off -- please
Behavioral biologists conducting research in the field often depend on state-of-the-art techniques. Consequently, damage to or theft of technical equipment represents a dramatic financial and scientific loss. Researchers from the Max Planck Institute for Ornithology in Seewiesen decided to find out whether the information content and tone of labels attached to the equipment could reduce the incidence of vandalism. In total 60 equipment dummies were distributed in four public parks in Munich. The researchers found that a friendly, personal label reduced the interaction of people with the equipment in comparison with neutral or threatening labels. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
