A San Antonio physician has completed a study that shows renal artery stents should no longer be recommended for patients with chronic kidney disease and high blood pressure. The new recommendations are predicted to save millions of dollars in future medical costs.
Dr. William Henrich, president of San Antonio’s UT Health Science Center, found that millions of renal stents placed in older patients with kidney disease and high blood pressure may not have done any good -- and created billions of costs in Medicare dollars.
Much of the modern education reform movement has centered around the drive for data. Standardized tests now gauge whether children are at grade level seemingly every few months. Kids are observed, measured and sorted almost constantly.
In Silicon Valley, a $20 billion industry does much the same thing — but for a different purpose.
Video game design has become a data-driven industry where games evolve depending on how they are played.
NPR's Richard Harris has covered the U.N. climate talks since the first treaty was negotiated in Rio de Janeiro in 1992. He's monitoring these new talks, and he joins us now to talk about this long-running argument over climate-related funding for the developing world. Richard, thanks for being here.
RICHARD HARRIS, BYLINE: My pleasure.

NASA's PhoneSat, a 4-by-4-inch CubeSat satellite, will use an Android smartphone as its motherboard. It was among the 29 satellites launched Tuesday from Wallops Island, Va. Another miniature satellite, developed by high school students, also was on board.
The first satellite ever developed by high school students to make it to space is believed to be orbiting Earth after getting a ride aboard a U.S. military rocket Tuesday night from Wallops Island, Va.
Fittingly, perhaps, you can send it a text message.
The satellite, using a voice synthesizer, is built to transform that text into an audio message that can be heard over certain radio frequencies around the globe, and in different languages.
For the past nine months, Princeton University in New Jersey has been trying to halt an outbreak of bacterial meningitis in its students without success. So it's going to offer students a vaccine that's not yet approved for broader use in the US.
