Methane has 30 times the warming effect of carbon dioxide but lacks the press awareness of its greenhouse gas cousin. 

And a new study in
Nature Geoscience has found that the seafloor off the coast of Northern Siberia is releasing more than twice the amount of methane as previously estimated - the East Siberian Arctic Shelf is venting at least 17  million tons
(teragrams) of methane into the atmosphere each year. 

Using chest pain characteristics (CPCs) specific to women in the early diagnosis of acute myocardial infarction (AMI, heart attack) in the emergency department does not seem to be supported by the findings of a new study.

While about 90 percent of patients with AMI present with chest pain or discomfort, some patients present without typical chest pain. Sex-specific differences in symptom presentation among women have received increasing attention. But it remains unclear whether identifying sex-specific CPCs is possible to help physicians differentiate women with AMI from women with other causes of chest pain, the authors write in the study background.

Playing violent video games not only increases aggression, it also leads to less self-control and more cheating, according to  a paper in Social Psychological and Personality Science.

The psychologists found that teens who played violent video games ate more chocolate and were more likely to steal raffle tickets in a lab experiment than were teens who played nonviolent games. The effects were strongest in those who scored high on a measure of moral disengagement – the ability to convince yourself that ethical standards don't apply to you in a particular situation. 

Awe-inspiring moments, like the sight of the Grand Canyon or the Aurora Borealis, might increase our tendency to believe in God and the supernatural, according to a new paper in Psychological Science which suggests that awe-inspiring sights increase our motivation to make sense of the world around us. Learning geology may be too hard to it's easier to default to aliens or religion. 

The government enjoyed tremendous success steering the goals of science in World War II and that continued during the NASA era. Since that time, government has exercised greater control of science through larger and larger pools of funding that have gradually supplanted corporate basic research.

But government control of funding has its downside; fashions in research funding (solar power now, before that), reward structures in universities that focus on government grants and streamlining of scientific agendas undermine traditional scientific norms and may even result in science bubbles.

If you have ever wondered about why you can tap a newly opened beer bottle and its suds will foam out and go all over the place, researchers from Carlos III University and Universite Pierre et Marie Curie, Institut Jean le Rond d'Alembert have provided some insight - by exploring the phenomenon of cavitation. 

Cavitation, a phenomenon relevant to such common engineering concerns as erosion of ship propellers, is the mechanism by which bubbles appear in a liquid such as beer after an impact, said Javier Rodriguez-Rodriguez, the lead researcher from Carlos III University.
