Boeing announced late Friday that it is postponing deliveries of its new 787 Dreamliner because of problems with its big batteries. Aviation authorities in the U.S. and abroad grounded the new jetliners after those batteries failed in two planes operated by Japanese airlines, including one battery that burned while the plane was on the ground.
These lithium-ion batteries are new to jetliners. They're powerful and lightweight, and, unfortunately, they're also fragile.

As the flu season grinds on from news cycle to news cycle, there's some flu news of a different sort. Federal regulators have approved a next-generation type of flu vaccine for the second time in two months.
The two new vaccines are the first fruits of a big government push to hasten and simplify the laborious production of flu vaccines.
Astronomers have discovered a clump of 73 quasars that spans four billion light years at its widest point--that's like 40,000 Milky Way galaxies lined end-to-end. The only problem? Theory says the quasar cluster is too big to exist. Astronomer Gerard Williger and reporter Ron Cowen discuss this cosmological oddity, and other news about the cosmos.
Last weekend, air pollution in Beijing reached record highs, raising concerns about the cost of China's rapid industrialization. David Pettit, of the Natural Resources Defense Council, discusses the pollution problem in China's capital, and why severe smog can be deadly.
Aside from getting the flu shot, how do you outsmart the wily virus? Hoard hand sanitizer? Dodge door knobs? Or quietly slink away from coughing commuters? Dr. Nicole Bouvier, a flu researcher at Mount Sinai School of Medicine, talks about what works--and what doesn't--in avoiding influenza.
This is SCIENCE FRIDAY. I'm Flora Lichtman. Up next: the man who wrote the book - well, the books, rather - on data visualization. He was doing infographics before everybody was doing infographics. Back in the '80s, data scientist Edward Tufte remortgaged his house so he could start a company and self-publish his first book, "The Visual Display of Quantitative Information." Sound like a snoozer? Well, that book, along with his others on the same topic, have sold more than a million-and-a-half copies.
This is SCIENCE FRIDAY. I'm Flora Lichtman, filling in for Ira Flatow today. Solar wind, geothermal - now there's a new renewable energy source to add to that list. It's free, completely reliable and totally unlimited: the force of gravity. Two British designers have invented a lamp that runs on gravity alone. Their GravityLight - yes, that's its name, aptly named - uses, you guessed it, the pull of gravity on a weight to generate up to 30 minutes of light.
In the Broadway play The Other Place actress Laurie Metcalf ("Jackie" on the TV show "Roseanne") plays a scientist suffering from the dementia she studies. Playwright Sharr White discusses the play and the challenge of presenting complicated science on a theater stage.

Retirees flock to Florida — and the Sunshine State even has a retirement home for chimpanzees.
There, chimps live in small groups on a dozen man-made islands. Each 3-acre grassy island has palm trees and climbing structures, and is surrounded by a moat.
This is Save the Chimps, the world's biggest sanctuary for chimps formerly used in research experiments or the entertainment industry, or as pets. The chimps living here — 266 of them — range in age from 6 years old to over 50. And as sanctuary Director Jen Feuerstein drives around in a golf cart, she recognizes each one.
