Driving With a Hangover Just as Dangerous as Driving Drunk
Driving home with a hangover may be just as dangerous as driving after too many glasses of champagne, according to a sobering new study. A team of researchers, led by Utrecht University psychopharmacologist Joris Verster, found that even when drivers’ blood alcohol levels returned to zero the morning after a night of partying, they showed the same degree of driving impairment as drivers who were intoxicated. “The hangover develops when blood alcohol concentration (BAC) returns to zero and is characterized by a feeling of general misery that may last up to 20 hours after alcohol consumption,” the researchers write.

Give, if You Know What’s Good for You
The New York Times: Vancouver, British Columbia — IN the classic children’s story “How the Grinch Stole Christmas!,” when the Grinch discovered the true spirit of the holiday, his “small heart grew three sizes that day.” Dr. Seuss may have been on to something — because it now appears that acts of generosity may bestow physical benefits on the donor. To be sure, there is plenty to hate about the holidays, when we endure the incessantly cheerful sounds of “Jingle Bells” spilling out of every shop and fight our way through overcrowded airports. But the holiday season can also inspire heartwarming generosity unmatched by other times of year.

Poverty’s Role in Intellectual Development
CityLab: Whether intelligence is more the product of nature or nurture has long fascinated American social scientists and the general public alike. Typically the result is explained as some balance of genetics and environment, but since the early 1970s, researchers have noticed that this scale tends to shift dramatically across social classes. It’s as if nature and nurture play by different rules for rich and poor. Generally speaking this work has found that genetic variance tends to explain the bulk of IQ scores for advantaged groups, whereas environmental variance plays a larger role for disadvantaged ones.

Be Kind, Unwind: How Helping Others Can Help Keep Stress In Check
NPR: Say it's Monday and it's a bad one. You overslept and definitely didn't shower, so your hair might smell and maybe you spill some coffee on your shirt while you're barreling toward the Metro, which is especially unfortunate because you're meeting with your boss at 9:30. Just when you think your bloodstream has reached maximum cortisol saturation, a slow-moving elderly man steps between you and the train doors. Then he drops his wallet. Do you rush past him because you're too stressed to deal and there are plenty of other people around to step up — or do you help the guy out?
