This photo, taken by NASA's Curiosity rover, shows Mars' Gale Crater, where the rover has taken samples for chemical analysis. Scientists believe that at some point in the very distant past, there was a riverbed here.
NASA is finally receiving data on Martian soil samples from Curiosity, its rover currently traversing the red planet. The results from the soil samples hint at something exciting, but rover scientists are making very sure not to raise expectations.

A notorious group of Internet trolls says it has unleashed a worm that has littered Tumblr blogs with inflammatory and racist posts.
According to the technology site The Verge, GNNA, whose full name we can't print in a family blog, says the worm has infected more than 8,000 accounts. The worm spread when users were logged into Tumblr and clicked on a viral — in more ways than one — post that asked for all Tumblr users to "drink bleach and die."

Step back, lobsters coming through!
This summer lobsters exploded in number along the Maine coast. There were so many crustaceans crawling along the ocean floor – and into fishermen's traps – that lobster prices plummeted. Many fishermen tied up their boats, and a price war even broke out between Canadian and Maine seafood distributors.
Brad Hines is a building contractor in Los Angeles who spends a good eight hours a day in his 2008 Dodge Ram. He talked to us from his truck — hands-free, of course.
"I do everything in my truck. I drive from job site to job site. I take calls. I try to get on the computer and clean up daily reports. I answer emails on my phone. I use my truck as a mobile office," Hines says.
The idea of the mobile office is far from new — Willy Loman; the Avon Lady; plumbers; electricians. Now, technology is taking the idea of working from the road to a whole new level.
NASA's Mars rover Curiosity cut a wheel scuff mark into a wind-formed ripple at the "Rocknest" site to give researchers a better opportunity to examine the particle-size distribution of the material forming the ripple.
The director of NASA's Jet Propulsion Laboratory said last week that preliminary data showed the possibility that the agency's Mars Science Laboratory – the six-wheeled rover that landed on Mars in August — had found signs of carbon-containing molecules.
Wildlife ecologist Danielle Garneau is making a habit of tracking down roadkill. She actually seeks it out, hunting for clues about larger ecological trends. Garneau records it all on a free smartphone app, EpiCollect.
Standing by the side of the road in upstate New York, phone in hand, Garneau peers down at a dead, bloody and smelly skunk.
On Dec. 3, 1992, Neil Papworth sent what is believed to be the first text message ever. "Merry Christmas," he wrote. Weekend Edition host Rachel Martin talks to NPR's Steve Henn about the evolution of the text message in the 20 years since.
