In the latest smog-related health scare in China, officials in Shanghai on Friday ordered schoolchildren to stay indoors, halted all construction and even delayed flights in and out of the city, which has been enveloped in a thick blanket of haze, reducing visibility in places to less than 150 feet.
NPR's Frank Langfitt reports from Shanghai that the commercial capital's Air Quality Index soared above 500 for the first time ever, according to government sensors. He says officials described the readings as "beyond index" — in layman's terms, off-the-charts awful.

This is SCIENCE FRIDAY, I'm Ira Flatow. For less than $100, you can buy a little gadget, a speedometer, that plugs into your car's cigarette lighter and it will let out a terrific scream when you exceed that speed limit that you preset into it. In fact, there's a 99-cent app for that too for your smartphone that tells you when you've exceeded the speed limit.
That, of course, is the theme of the longest running sitcom in American history. "The Simpsons" kicked off its 25th season this year. And if you've ever seen the show, you know how Homer Simpson is no math genius. He's more interested in the pie of pastry than 3.14. But in the episode "The Wizard of Evergreen Terrace," Homer does something extraordinary. He seems to have found a counter example to the notorious math problem Fermat's Last Theorem. What's going on here?

This is SCIENCE FRIDAY. I'm Ira Flatow. Do you know that what the number one reason for people filing bankruptcy in this country is? What's the number one reason? Not a lost job. It's not damage from earthquakes or floods. It's medical bills. My next guest says our high-priced medical treatments are responsible for some 60 percent of personal bankruptcies. And if you think you're safe because you have insurance, he says think again.
This is SCIENCE FRIDAY. I'm Ira Flatow. On July 20th, 1969, Neil Armstrong, Buzz Aldrin and Michael Collins were five days into their journey to the moon. As he prepared for his historic landing, Buzz Aldrin received this advisory from Houston.
The HIV virus has proven once again that it can evade detection in the body.

HIV has reappeared in the blood of two Boston patients who scientists had hoped had been cured of their infections.
This disappointing development, reported by The Boston Globe's Kay Lazar, is yet another cautionary tale of how researchers can never afford to underestimate the human immunodeficiency virus's ability to hide out in patients' bodies and overcome their most ingenious efforts to eliminate it.
This is an alarming story, not because it ends badly. It's alarming because it ends well. It shouldn't have, but it did, and biologists (and especially conservationists) now have a puzzle to ponder.
The story begins in central China, in an apple-growing region called Maoxian County, near the city of Chengdu. In the mid-1990s, the bees that regularly showed up there every spring suddenly didn't. Apple farmers, obviously, need bees. Bees dust their way through blossoms, moving from flower to flower, pollinating, which helps produce apples in September.

Wildlife officials in southwest Florida who are struggling to save dozens of beached pilot whales say there's hope that at least some of the animals might escape after they spotted at least 20 of them swimming in deeper water.
