The repair and regeneration of tissues using endogenous stem cells represents an ultimate goal in regenerative medicine. To our knowledge, human lens regeneration has not yet been demonstrated. Currently, the only treatment for cataracts, the leading cause of blindness worldwide, is to extract the cataractous lens and implant an artificial intraocular lens. However, this procedure poses notable risks of complications. Here we isolate lens...

Macromolecular diffractive imaging using imperfect crystals
The three-dimensional structures of macromolecules and their complexes are mainly elucidated by X-ray protein crystallography. A major limitation of this method is access to high-quality crystals, which is necessary to ensure X-ray diffraction extends to sufficiently large scattering angles and hence yields information of sufficiently high resolution with which to solve the crystal structure. The observation that crystals with reduced unit-cell volumes and tighter...
360-degree dunks! NBA using freeD to deliver high-tech replays of All-Star action
A week after we wrapped our heads around Super Bowl action via dramatic new camera technology, the NBA will be deploying 360-degree replay views of its own at Sunday’s All-Star Game in Toronto. Who got that loose ball? Did he step out of bounds? I need to...
Russell Wilson touts Bing after being accused of using Google to express love for Ciara
As a business, Twitter is struggling. But dang, the social media platform sure is providing some serious entertainment this week. After Wednesday gave us Wiz Khalifa and Kanye duking it out, and later Paul Graham arguing with Mark Cuban about Shark Tank, the latest Twitter fun went down Thursday afternoon. It started after...
Uber tests out using smartphones to monitor driver behavior

Uber announced today that it will monitor some of its drivers' behavior for things like excessive speeding or distracted driving. Starting with a trial in Houston, the program will use Uber drivers' own smartphones to provide data to the company.
The company will use a phone's gyroscopes, accelerometers, and GPS to record whether drivers break speed...
Report: Google paid Apple $1B in 2014 for using its search engine on iPhone
Google paid Apple $ 1 billion in 2014 to use its search engine on the iPhone, according to court records dug up by Bloomberg News. The disclosure provides new details about the complicated relationship between Apple and Google, whose iOS and Android operating systems are rivals in the...
Netflix cracks down on customers using VPNs, proxies, and unblockers
Netflix is aiming to block unblocking services like this one. (credit: TVUnblock)
Netflix says it will step up enforcement against subscribers who use VPNs, proxies, and unblocking services to mask their locations. This will help Netflix prevent customers from watching video that isn't licensed for viewing in their country, but it may also affect people who use location-spoofing services...
Measurement noise 100 times lower than the quantum-projection limit using entangled atoms
Quantum metrology uses quantum entanglement—correlations in the properties of microscopic systems—to improve the statistical precision of physical measurements. When measuring a signal, such as the phase shift of a light beam or an atomic state, a prominent limitation to achievable precision arises from the noise associated with the counting of uncorrelated probe particles. This noise, commonly referred to as shot noise or projection noise,...
