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.
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.
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.

It's deja vu all over again in Maine.
For the first time in years, a state has acted to allow its citizens to purchase prescription drugs by mail from other countries. The idea is to take advantage of those nations' lower prices, which can be half the cost of those at American pharmacies.
Twenty percent of strokes hit people under age 65, and the cause of many of those strokes remains a mystery. Having had a concussion or other traumatic brain injury might make the risk of a stroke more likely, a study says.
Back in 2011, researchers in Taiwan had unearthed an association between traumatic brain injury and stroke by combing through hospital records.
It's one of those "Oh, really?" findings that gets scientists itching to check it out themselves.
