Elinor Ostrom, the only woman ever to win an economics Nobel, died today at age 78.

She was famous for challenging an idea known as the tragedy of the commons — the theory that, in the absence of government intervention, people will inevitably overuse a shared resource.

So, for example, if a village shares a pasture, it's in the individual interest of each farmer to graze his cattle as much as possible on the pasture even though, in the long run, overgrazing may ruin the pasture for everyone.

The music made by Thomas Wesley Pentz, better known by his stage name, Diplo, is one part club-music mashup and one part pop music forecast. In 2009, he took bubblin' — a syncopated house style born in the clubs of Holland — as inspiration and collaborated with fellow DJ Switch, his partner in the group Major Lazer, to make the dance-floor hit "Pon de Floor." But he wasn't done with the bubblin' sound yet. In 2011, he used that song as basis for "Run the World (Girls)," a single by the pop star Beyonce.

Recreational rehabilitation programs have long been a favorite for helping disabled veterans acclimate after war, and the number of young and disabled vets returning who need those services is on the rise.

Two brothers — with nearly 60 years of military service between them — are trying to help with a unique retreat that's free for young vets. The program gets them out of their hospital beds for a few days to hunt in rural Pennsylvania.

An influential panel of experts questioned two big reasons people take vitamin D supplements.

The U.S. Preventive Services Task Force concluded in draft recommendations released Tuesday that taking less than 400 international units of vitamin D and 1,000 milligrams of calcium every day doesn't reduce the risk for bone fractures among postmenopausal women. And so the task force recommended against doing that.

A rash of kidnappings in Lebanon over the weekend, coupled with deadly cross-border attacks by the Syrian army, are all worrying signs that Syria's troubles are continuing to spill over into its smaller and weaker neighbor.

In the most recent incidents, a Sunni sheik known to support the Syrian uprising was abducted. In retaliation, several Alawites aligned with the Syrian government were taken. Days before that, the Syrian army shot several people on Lebanese territory.
