Swiped Tokens Expose Android Devices To Data Theft
tsamsoniw writes "Researchers at the University of Ulm have found that eavesdroppers can intercept and use authentication tokens sent between Android apps and Google services via unsecured Wi-Fi. Those tokens, which aren't tied to specific devices or sessions, can be used to peek at and tweak a user's email, contacts, and calendar. Devices running Android 2.3.3 or earlier (which accounts for the vast majority of phones) are most vulnerable, but there are steps devs, Google, and users can take to reduce the risks." -
Integrated Reflector Could Lead to Ubiquitous LEDs
Andreas writes "Professor Schubert says he has found a way to raise the efficiency of LEDs to 99%. From an article on Advanced Technology: "Until now, all lighting systems, especially incandescent bulbs, generated more heat than light. But our 99-percent efficient reflectors for LEDs makes them the first candidate for light-bulb replacement that generates more light than heat," said Schubert."
