Mystery Bursts Baffle Astronomers http://kccu.org/post/close-encounters-radio-kind-mystery-bursts-baffle-astronomers Astronomers have a mystery on their hands. Two large radio telescopes, on opposite sides of the planet, have detected very brief, very powerful bursts of radio waves.<p>Right now, astronomers have no idea what's causing these bursts or where they're coming from. And nothing has been ruled out at the moment — not even the kind of outrageous claims you'd expect to see in tabloid headlines.<p><strong>Australian Recordings Inspire Curiosity And Doubt</strong><p>The first report of these "fast radio bursts" appeared in 2007.

Once there, the Rosetta probe will take pictures, make measurements and drop a probe down to the comet's surface.

That indicates that black holes are more common than astronomers previously thought.

Plots unfold. And this summer, NPR science correspondent Joe Palca has been telling us how science unfolds. It's series we're creatively calling Unfolding Science.<p>(SOUNDBITE OF THEME SONG)<p>BLOCK: Today, Joe tells us about large biological molecules called proteins that have to fold and unfold properly to keep us alive.<p>JOE PALCA, BYLINE: When we talk about food, protein is a kind of nutrient you get in meat, fish or foul.
