Half of all U.S. adults now have a mobile connection to the web through either a smartphone or tablet, significantly more than a year ago, and this has major implications for how news will be consumed and paid for, according to a new survey by the Pew Research Center's Project. We’ll go behind the numbers this morning with Jesse Feiler.
With the release this week of Apple’s iPhone 5, the Pew Research Center reports 45% of American adults own smartphones. They are particularly popular with young adults and those living in relatively higher income households; 66% of those ages 18-29 own smartphones, and 68% of those living in households earning $75,000 also own them. Duh, right?

Arctic sea ice has melted dramatically this summer, smashing the previous record. The Arctic has warmed dramatically compared with the rest of the planet, and scientists say that's what's driving this loss of ice.
To be sure, ice on the Arctic Ocean always melts in the summer. Historically, about half of it is gone by mid-September. But this year, three-fourths of the ice has melted away, setting a dramatic new benchmark.

It was the absence of feathers that got conservation biologist Thor Hanson thinking about the significance of them. Hanson was in Kenya studying the feeding habits of vultures, and he noticed the advantages that vultures had relative to other birds because of their bare, featherless heads.
"Having lost their feathers allows [vultures] to remain much cleaner and more free from bacteria and parasites and disease," Hanson tells Fresh Air contributor Dave Davies.

It didn't go far, but the NASA rover Curiosity has taken its first test drive on Mars.
"This is how I roll," NASA writes (speaking for Curiosity) with a photo it has released showing the rover's first tracks. "Forward 3 meters, 90 [degree] turn, then back. Electric slide, anyone?"
"We have a fully functioning mobility system," NASA engineer Matt Heverly just told reporters. He said Curiosity ended up moving about 4 1/2 meters during today's test. It also did a full revolution going forward, backed up and did another revolution.
An experimental aircraft that designers hoped would hit 3,600 mph in a test flight over the Pacific on Tuesday "suffered a control failure" and failed in its attempt to go hypersonic, The Associated Press writes.
