Man Dies in Collision While Being Driven by Tesla’s Autopilot System

A Tesla blog post describes the first fatality involving a self-drive system. A Tesla was driving on autopilot down a divided highway. A truck taking a left turn off the highway crossed into the Tesla's lane perpendicular to the car. A white truck body against a bright sky is not something the camera system in the Tesla perceives well. The truck's clearance was high, so when the Tesla did not stop, it went under the truck and the windshield... read more

Why Your Smartphone’s Battery Sucks Is Finally Revealed

When it comes to modern consumer electronics, we all seem to be obsessed with finding an electrical outlet to charge up. That’s because the lithium-ion batteries that power our smartphones, laptops, and other gadgets have a performance problem: with each charge, they become less efficient, eventually becoming too unstable to function. Now chemists from Texas A&M have uncovered what causes batteries to slowly die: instead of flowing freely, electrons coupled to lithium ions are getting... read more

Smart Dust Is Coming: New Camera Is the Size of a Grain of Salt

Miniaturization is one of the most world-shaking trends of the last several decades. Computer chips now have features measured in billionths of a meter. Sensors that once weighed kilograms fit inside your smartphone. But it doesn't end there. Researchers are aiming to take sensors smaller—much smaller. In a new University of Stuttgart paper published in Nature Photonics, scientists describe tiny 3D printed lenses and show how they can take super sharp images. Each lens is 120 millionths of a meter in... read more
