About 20 scientists are clustered in a cramped conference room in San Diego, one of the country's science hubs, but they aren't there to pore over their latest research. Instead, this is a meeting of BioToasters — a chapter of the public speaking organization Toastmasters, geared specifically toward scientists.
"For a typical scientist, they will spend a lot of time at the bench, so they're doing a lot of maybe calculations or lab work where they're not interacting directly from person to person," says BioToasters President Zackary Prag, a lab equipment sales rep.
There is a broad scientific consensus that to keep global warming in check, we need to phase out 80 percent of all oil, coal and natural gas by midcentury. President Obama has set a nonbinding target to do precisely that.
There are technologists who say this national goal is well within reach, but there are also economists who are quite pessimistic about those prospects. And you can find this range of opinion on the University of California, Berkeley campus.
ARI SHAPIRO, BYLINE: It's ALL THINGS CONSIDERED from NPR News. I'm Ari Shapiro. The 2013 Atlantic hurricane season ends tomorrow. It'll be remembered as one of the quietest on record. Since June, there have been just two hurricanes, both were relatively weak. As NPR's Jon Hamilton reports, forecasters were expecting something very different.
JON HAMILTON, BYLINE: The National Oceanic and Atmospheric Administration told Americans to expect an unusually active year with between seven and 11 hurricanes. Other forecasters offered variations on that theme.
If you find yourself stuck in holiday traffic this weekend, our next story won't help you much, but it does bring hope for a less stressful future. A computer scientist at the Massachusetts Institute of Technology thinks he's found a way to eliminate at least one kind of really annoying traffic jam. NPR's Joe Palca explains.
Think back to an important event in your life: a graduation, a birth, a special Thanksgiving dinner. Chances are you're remembering not only what happened, but also where it happened. And now scientists think they know why.
As we form so-called episodic memories, the brain appears to be using special cells in the hippocampus to "geotag" each event, researchers report in Science. The process is similar to what some digital cameras do when they tag each picture with information about where the image was taken.
Last December, a website called The Morning Newsasked me to describe the most important and unimportant events of my year. So I sent them a story that felt like both to me, something slight but at the same time deeply rich. Now that it's Thanksgiving, I'm going to post it here because it's about two girls who want the best for everybody — and that can get complicated.
Those of us who were schoolchildren in the 1950s and 1960s remember duck-and-cover drills: in our classrooms, we practiced dropping under our desks in order to protect ourselves in case a nuclear bomb went off.
