The most worrisome element of climate change isn't a gradual increase in global temperatures. The National Academy of Sciences says we need to be concerned about — and better prepared for — abrupt changes. A new study outlines ways to anticipate and prepare for rapid changes that could affect everything from agriculture to sea level.
The space agency has announced plans to grow turnips, basil and cress on the moon by 2015. The experiment could be good news for astronauts sick of their freeze-dried fare. But researchers say the real goal is to see if humans could one day live — and farm — on the moon.
A cookie in the oven almost looks like a monster coming alive. It bulges out, triples in size and then stiffens into a crisp biscuit. So how does an oven turn raw dough into a delight? A new animation explains the chemistry behind great baking so you, too, can unleash your inner mad scientist in the kitchen.
Look inside most machines today and what do you find? Computer chips functioning mysteriously. Gaze at a 1920's Rube Goldberg cartoon and what do you find? Machines powered by hungry parrots and angry ladies. Will future tools stay inscrutable or become more Rube-like? Here's a guess.
The U.S. aims to reduce carbon dioxide emissions by 80 percent by 2050. Wind and solar power can help. But folks doing the math say other pricey, controversial technologies — such as burying carbon gas underground, and expanding nuclear power — are also likely to be part of a low-carbon future.
You can't tickle yourself because you can't surprise your own brain. But could you do it if you could trick your brain into thinking you were someone else? Host Rachel Martin talks to professor Jakob Hohwy of Monash University in Australia to learn about his experiment with illusion and reality, and the rubber hand.
Reporter Emily Graslie explores natural history museums, showing us what's going on behind the scenes. Her viewers write her, of course, and in this video, she reads some of those letters. They're not about science. Or Museums. They're about Emily. And it's embarrassing.
Science isn't known as a career field that attracts showboats. But academics must give seminars, pharmaceutical researchers present results, and graduate students defend their work. In San Diego, one of the country's science hubs, a group aims to teach scientists the art of small talk and public speaking.
