Here's a new, sly (and frankly selfish) way to think about global warming: Instead of worrying about the whole planet and all its oceans, how about asking a more personal question ...

What about me? What about where I live? Or where my grandma lives? Or the North Pole? Or Siberia? What if I could take my cursor, plop it onto any place on Earth and find out what's happened to temperatures right there.

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.

Edward Tufte Wants You to See Better

Transcript

FLORA LICHTMAN, HOST:

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.

Inventors Design Lamp Powered Entirely By Gravity

Transcript

FLORA LICHTMAN, HOST:

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.

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.

How Do You Fend Off The Flu?

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.
