Discovered: Teen driving laws work, a delicious way to lose weight, cheap drugs aren't always the best kind of drugs, and our oceans can't hold all of our carbon dioxide anymore.

  • Teen driving laws that work. Sorry eager-to-drive teens, the chart kind of says it all: as more states have so called graduated driving laws for teens (which limit things like the number of passengers allowed in the car or a curfew) have reduced drunk driving among teens. "Teens in states with the strongest laws were less likely to drive after drinking or to ride in a car with a driver who had been drinking," explains researcher Patricia A. Cavazos-Rehg. "In states with the toughest laws, teens were half as likely to engage in those risky behaviors." Sorry, kids. [Washington University School of Medicine]
  • A delicious way to lose weight. Not only do fruits and vegetables help a smoker quit, but certain fruits might also curb obesity and diabetes. "Our studies have shown that stone fruits – peaches, plums and nectarines – have bioactive compounds that can potentially fight the syndrome," explains Dr. Luis Cisneros-Zevallos. "Our work indicates that phenolic compounds present in these fruits have anti-obesity, anti-inflammatory and anti-diabetic properties in different cell lines and may also reduce the oxidation of bad cholesterol LDL which is associated to cardiovascular disease." So, America, stock up on your stone fruits. Just in time for summer, too! [American Chemical Society]
  • Cheap drugs aren't always the best kind of drugs. We know healthcare has gotten too expensive and everything, but in this particular case the pricier option really is the better choice. Looking at patients treated with two tiers of drugs for Age-related Macular Degeneration, science found some scary adverse effects of the budget choice, finding it could lead to eye-inflammation, a potentially blinding side-effect. Patients who got the cheapo drug had a 12 times higher risk of serious eye inflammation and some patients also lost their sight. Splurge on this one, okay? [Queen's University]
  • There's a lot of carbon dioxide in the oceans. Too much carbon dioxide actually and the oceans can't really handle it all anymore. Care to guess where it goes? "The river water contains high levels of organic matter, which is partially broken down to carbon dioxide in the sea. This leads to the level in the sea being higher than in the air, and thus carbon dioxide flows from the sea into the air, accelerating climate change," explains researcher Iréne Wåhlström.
