In the latest installment of our "Looking Ahead" series, NPR science correspondent and Radiolab co-host Robert Krulwich talks about reporting on big ideas in imaginative ways, the old days at NPR and what he's wondering about today.
"The head of Saudi Arabia's religious police has warned citizens against using Twitter, which is rising in popularity among Saudis," the BBC reports. "Sheikh Abdul Latif Abdul Aziz al-Sheikh said anyone using social media sites — and especially Twitter — 'has lost this world and his afterlife.' "
After President Obama overturned Bush-era policy restricting federal funding of embryonic stem cell research in 2009, Nebraska Right to Life led a protest of the research outside the University of Nebraska regents' meeting.
This map, from the United States Geological Survey, shows the age of bedrock in different regions of North America. Scientists found ancient water in bedrock north of Lake Superior. This region, colored red, was formed more than 2.5 billion years ago.
Mars, seen in this composite image, has a lot of water in its polar ice caps. If water is also trapped in the planet's crust, experts say, it could house microbial life.
Scientists have discovered water that has been trapped in rock for more than a billion years. The water might contain microbes that evolved independently from the surface world, and it's a finding that gives new hope to the search for life on other planets.
The water samples came from holes drilled by gold miners near the small town of Timmins, Ontario, about 350 miles north of Toronto. Deep in the Canadian bedrock, miners drill holes and collect samples. Sometimes they hit pay dirt; sometimes they hit water, which seeps out from tiny crevices in the rock.
Astronomers said Wednesday that a reaction wheel that keeps the orbiting telescope pointed at tiny, distant patches of sky to look for Earth-like planets has failed. If they can't fix it, Kepler will be relegated to a less prestigious mission, directing its gaze much closer to home in a search for so-called "near-Earth objects," i.e., meteors and asteroids.
The competition for your ears — and dollars — just got a little tougher. On Wednesday, Google launched a paid music subscription service that will put it in direct competition with other streaming services like Spotify and Pandora. The announcement may just be the beginning for Google.
