Climate scientists have a good reason to want to get away from it all. To get an accurate picture of the amount of carbon dioxide in the Earth's atmosphere, you have to find places where the numbers won't be distorted by cities or factories or even lots of vegetation that can have a major local impact on CO2 concentrations.
And Flora Lichtman is here with our Video Pick of the Week. Hi, Flora.
FLORA LICHTMAN, BYLINE: Hi. It's multitasking's - you know, what goes best with multitasking? A big cup of coffee.
LICHTMAN: That's what our video is about this week. Our continuing coverage of this hard-hitting serious issue: What is the science in your morning Joe? So our video this week was put together by video producer Jenny Woodward. And this one goes into the gear.
Children with autism see simple movements twice as fast as other children their age, a new study finds.
Researchers at Vanderbilt University and the University of Rochester were looking to test a common theory about autism which holds that overwhelming sensory stimulation inhibits other brain functions. The researchers figured they could check that by studying how kids with autism process moving images.
Earth's atmosphere is entering a new era. A mountaintop research station that has been tracking carbon dioxide for more than 50 years says the level of that gas in our air has reached a milestone: 400 parts per million.
That number is one of the clearest measures of how human beings are changing the planet. It shows how much carbon we have put into the air from burning fossil fuels — and that carbon dioxide drives global warming.
This measurement comes from Mauna Loa, Hawaii, a remote volcano where the air is largely free of local influences.
The SETI (Search for Extraterrestrial Intelligence) Institute's Jill Tarter has spent decades searching for the signals that would tell us we aren't alone in the cosmos. Tarter discusses the hunt, and what the presence of intelligent life elsewhere might tell us about our own future on Earth.
David Matsumoto, a psychology professor at San Francisco State University, trains national security officials and police officers to recognize "microexpressions"--fleeting, split-second flashes of emotion across someone's face. Matsumoto says those subtle cues may reveal how an interview subject is feeling, helping officials to hone their line of questioning.
Up next, we'll be focusing on you and your true love - your smartphone. Think about it. Are you lost without it? Inconsolable if the two of you are separated? Willing to walk into a lamppost rather than look up while texting? Is it the object of your desire? Isn't it?
Saul Perlmutter shared the 2011 Nobel Prize in physics for his discovery that the universe was expanding at an accelerating rate. Perlmutter explains how supernovae and other astronomical artifacts are used to measure the expansion rate, and explains what physicists are learning about "dark energy" — the mysterious entity thought to be driving the acceleration.
What would it be like to be a string that made music? Not anything simple, like a guitar string or a cello string, but a magical string, a sine curve that's taut then loose, that doubles then doubles again, that sheds then dissolves into showers of notes — a flaming, sighing, looping, dissolving string. Curious?
