Like the rest of the developed world, Europe is getting a lot fatter, and public health experts in Europe have found a correlation for the upward spike in youth obesity - the low birth rate. They say only children, singletons, have a more than 50 percent higher risk of being overweight or obese than children with siblings. Over 22 million children in Europe are estimated to be overweight.

On the road to true Open Publishing, where taxpayer money isn't used to pay to publish or to read already taxpayer-funded studies at all, the Sponsoring Consortium for Open Access Publishing (SCOAP) in Particle Physics has set a new waypoint, and Oxford University Press has signed up Progress of Theoretical and Experimental Physics (PTEP) for this new transparent model of open access, where members can see how the taxpayer money is being spent.  

Emotions tag our experiences and act as waypoints in how we steer our behavior, but they seem to be subjective. Avoiding danger and pursuing rewards is essential for successful navigation through a complex environment, and thus for survival, but why are some people afraid of harmless spiders yet most are not afraid of incredibly dangerous horses?

The search for the neural correlate of emotions fascinates neuroscientists and psychologists – emotions are a central part of our mental selves.

Did Sen. Barack Obama buy the election of 2008, given that he bypassed public financing and so was able to raise and spend twice as much money as Sen. John McCain?  In 2012, the concern is the high spending by PACs but the playing field is level, both campaigns can raise and spend as much as possible this election and they will; each candidate this year will spend as much as the entire 2004 election, the last time both candidates held themselves to public financing limits.

Is your decision-making suspect?  Do you continually date strippers or bad boys who are 'getting their band together' and wish you could instead replace your own judgment with a prosthesis?

Maybe one day.  Researchers at Wake Forest Baptist Medical Center have created a prosthetic device which is capable of restoring decision-making due to reduced capacity due from brain disease or injury - in non-human primates, anyway.

Variation in facial shape is an easy way to explain phenotypes in humans to people who don't understand biology all that well. Monozygotic twins have almost identical faces and siblings usually have more similar faces than unrelated people, implying our facial morphology is under genetic regulation - but still little has been known about the genetic basis of normal human facial morphology.
