Science / Tech News Last Update on November 25, 2015 08:06 GMT IN THE NEWS: PHONE ENCRYPTION EXPANDING, TO FEDS' DISMAY NEW YORK (AP) -- The positive news: the smartphone you are carrying around these days probably does a much better job of protecting your privacy, thanks to encryption. The not-so-positive upshot of that: that same technology makes it harder for authorities to track possible national-security threats. Over the years, tech companies have stepped up their use of scrambling technology that keeps others from nosing around in your data. But police and intelligence agencies have been trying to thwart that same technology to go after those they want to find -- or to keep an eye on. In the wake of the Paris attacks, U.S. officials are pushing for limits on the use of encryption, though there's no evidence yet the terrorists involved used it to shield their communications. IN THE NEWS: SELF-DRIVING CARS MAKE PROGRESS LOS ANGELES (AP) -- It appears the Feds are putting the brakes on their resistance to self-driving cars. A couple of years ago, the U.S. Department of Transportation said in its official policy statement it opposed the idea of having self-driving cars hit the mainstream. But now, Transportation Secretary Anthony Foxx says the policy is being updated. It's unclear what the new policy will be. But Foxx says while the government wants to be aware of safety issues, he doesn't want the DOT "to be skittish" about embracing the idea of self-driving cars.
