Her techniques aren't super-sophisticated. She's not a leader in the field. She's more or less an amateur. This is what you can do with ordinary genetic engineering tools right now. Artist Heather Dewey-Hagborg can find a cigarette lying on the sidewalk on Myrtle Avenue in Brooklyn, and working from traces of saliva, by pulling DNA out of those saliva cells and using a bunch of simple algorithms available online, she can make some very educated guesses about what the smoker might look like.

What if we could get our gasoline, diesel fuel and jet fuel from yeast instead of from oil wells? That's not as crazy as it sounds. In fact, it's already happening on a small scale. And there's a vigorous research effort to ramp this up on a massive scale.

One of the more innovative approaches uses a new technology called "synthetic biology." Jay Keasling is one of the leaders in this hot field.

The U.S. is ready for tornadoes, but not tsunamis.

That's the conclusion of a panel of scientists who spoke this week on "mega-disasters" at the American Geophysical Union's science policy meeting in Washington, D.C.

The nation has done a good job preparing for natural disasters like hurricanes and tornadoes, which occur frequently but usually produce limited damage and relatively few casualties, the panelists said. But government officials are just beginning to develop plans for events like a major tsunami or a large asteroid hurtling toward a populated area.

Climate change seems like this complicated problem with a million pieces. But Henry Jacoby, an economist at MIT's business school, says there's really just one thing you need to do to solve the problem: Tax carbon emissions.

"If you let the economists write the legislation," Jacoby says, "it could be quite simple." He says he could fit the whole bill on one page.

Basically, Jacoby would tax fossil fuels in proportion to the amount of carbon they release. That would make coal, oil and natural gas more expensive. That's it; that's the whole plan.

From California to the Great Lakes, persistent water pollution shows that no beach is an island when it comes to public health threats like hepatitis, dysentery and stomach flu.

The Natural Resources Defense Council released its annual beach report card Wednesday detailing the levels of bacteria hanging around beaches across the nation.
