Physicists doing economics has gotten a bad rap - a practically worldwide recession will do that - but it's no reason to give up, especially if you are of the world view that redistributing wealth is better than a free market.

Models designed to represent taxation and wealth redistribution could be adjusted to create a target level of wealth distribution, according to mathematical physicists from the Free University of Bozen-Bolzano, Italy. 
Our immune systems are funny things. An American traveling to Taiwan, for example, might be warned to get a hepatitis vaccine - unless they grew up on a farm. Rabies is even scarier.  If you are bitten by an unknown animal, it requires a series of painful injections because if clinical disease sets in, it is usually fatal.
We can't complain that children don't know how to think and act like adults if we homogenize the way children behave...but criminologists wish you would.   If you don't, they could be drug addicts.

Defiant kids are correlated with drug dependence - they include cigarettes along with pot and cocaine, naturally - according to surveys analyzed by psychologists at Sainte-Justine University Hospital Center’s (UHC) Research Center and the University of Montreal, concluded following a 15-year population-based paper published in Molecular Psychiatry.
Most methane comes from natural gas - natural gas used to be loved but once it got popular it got lumped in with mean old fossil fuels so the search is on to find a new, green approach to methane, using microbes that can convert renewable electricity into carbon-neutral methane.

Researchers are raising colonies of microorganisms, called methanogens, which have the ability to turn electrical energy into pure methane, the key ingredient in natural gas. The scientists' goal is to create large microbial factories that will transform clean electricity from solar, wind or nuclear power into renewable methane fuel.
NGC 1187, a spiral galaxy about 60 million light-years away in the constellation of Eridanus (The River), may look tranquil but it's home to some violent events. NGC 1187 has hosted two supernova explosions during the last thirty years, the latest one in 2007.

NGC 1187 was discovered in England by William Herschel in 1784 and can be seen almost face-on, which gives astronomers a good view of its spiral structure. About half a dozen prominent spiral arms can be seen, each containing large amounts of gas and dust. The bluish features in the spiral arms indicate the presence of young stars born out of clouds of interstellar gas.
Modern lifestyles are quite different from those of our hunter-gatherer ancestors. That seems obvious. People looking to apply blame for the obesity rise focus on their own agendas, be it lobbying against GMOs, high fructose corn syrup or video games. Or contend it is because we don't spend our days picking berries.

But what does science say?  There's no way to know but anthropologists are at least taking a shot at it. A new analysis, of modern hunter-gatherers anyway, found that there is no difference between their energy expenditure and Westerners, casting doubt on 'we don spend all day picking berries' hypothesis for obesity.
