Ten years after carbon emissions happen, the warming effect is maximized. Methane is even quicker, and far more potent, though it also disappears much more rapidly.

It's always a good idea to reduce cost and radiation and when it comes to kids and chest X-rays, that cost reduction should be happening a lot more.

If you ask a female doctor why she didn't go into physics, she is not going to tell you it's because there are more men in physics and that is intimidating. Instead, she will say it's because she wanted to help people or she liked medicine.

Yet a number of sociological claims insist she doesn't really know why she chose not to go into physics, and it may instead be because of subtle self-bias or stereotype threat. 

If you have talked to ranchers or people who live near wolves about being able to shoot them without landing in prison with a mandatory Federal jail sentence, the response is clear: Wolves have to be controlled. If you talk to urban activists or people who hike on state game lands a few weekends a year, wolves are cute and anyone who shoots one should go to jail.

Yet that is not the real issue, according to the authors of a new paper that used surveys as their evidence. They believe the reason for the rancor is fear of wolves or the urge to care for canis lupis. It's simply social identity theory at work. People who live near wolves have never heard of that but they already know where the article in PLOS ONE is going.

The sons of fathers with criminal records tend to have less intelligence than sons of fathers with no criminal history, according to data from over 1 million Swedish men compiled as part of the Swedish mandatory conscription program.

 Population analyses have found that children of parents who engage in "antisocial" behaviors, such as rule-breaking, aggressive, or violent behavior, are at greater risk for various negative outcomes, including criminality, psychiatric disorders, substance use, and low academic achievement. Other papers have found that individuals who engage in antisocial behaviors tend to have poorer cognitive abilities than those without antisocial tendencies. 

In the classical game theory match-up known as the Prisoner’s Dilemma, two prisoners kept isolated from each other are offered a deal: they can confess to a crime and if their accomplice remains silent the charges will be dropped in exchange for testimony against the other. If they both confess, they can both get early parole. If both remain silent, they get convicted of a lesser charge.
