The ailing Kepler planet-hunting telescope cannot be fixed, the victim of failed reaction wheels required to aim the instrument. However, researchers still have reams of data to sift through. William Borucki of NASA and Joshua Winn of MIT discuss the search for distant planets.
Reporting in the Proceedings of the National Academy of Sciences, researchers write of a possible link between copper in drinking water and Alzheimer's disease in mice. Lead author Rashid Deane discusses the potential mechanism.
When you see them on the beach, spinach-like plops of green sprawled on the sand, you'd never guess their teeny nervous systems are imprinted with beach-ness. They are the ultimate Beach Boys. For them it's always summer.
For the second time in four months, the consumer group Public Citizen is alleging that a large, federally funded study of premature infants is ethically flawed.
Both complaints raise a big issue that's certain to get more attention beyond these particular studies: What's the ethically right way to do research on the validity of the usual care that doctors provide every day.
The U.S. Department of Health and Human Services will host an unusual forum on that question next Wednesday — stimulated by the sharp questions raised by Public Citizen.

When there's room to spread out, we often take advantage of it. Think about a big car or an SUV. You're behind the wheel, you roll the window down. You might prop up your left elbow. The other arm is outstretched on the wheel. It all sounds nice and relaxing, but it could have some major consequences. There's new research suggesting that you are more likely to blow a stop sign or a red light and not even know it. NPR's social science correspondent Shankar Vedantam is here to explain this.
The Fukushima-Daiichi nuclear power plant is back in the news more than two years after an earthquake and tsunami triggered a series of meltdowns. New leaks found this week prompted regulators to consider raising the alert level there in Japan. NPR's science correspondent Geoff Brumfiel joined us to explain. Geoff, good morning.
There's a joke among scientists: Prediction is difficult, especially about the future. For Ross Stein, it wasn't a joke after the Indian Ocean quake and tsunami in 2004. It killed some 275,000 people. "I just felt almost a sense of shame," Stein says, "that this tragedy could have been so immense in a world where we have so much intense research effort."
