Help wanted: Fast food cashier, $15 an hour Posted: 20 Jan 2015 12:50 PM PST Researchers have released a working paper verifying the ability of American fast food restaurants to more than double the minimum wage of their lowest paid workers to $15 an hour over a four-year period without causing the widespread employment losses and decline in profits often cited by critics of such increases.

Greenland Ice: The warmer it gets the faster it melts Posted: 20 Jan 2015 12:12 PM PST Melting of glacial ice will probably raise sea level around the globe, but how fast this melting will happen is uncertain. In the case of the Greenland Ice Sheet, the more temperatures increase, the faster the ice will melt, according to computer model experiments by geoscientists.

Facebook not to blame for negative impact on grades, professor says Posted: 20 Jan 2015 11:25 AM PST The more time college students, particularly freshman, spend on Facebook, the more their grades suffer. But a professor says the problem is not Facebook -- it's an issue of self-regulation.

New signal amplification process set to transform communications, imaging, computing Posted: 20 Jan 2015 08:12 AM PST A new signal amplification process is now poised to fuel new generations of electrical and photonic devices -- transforming the fields of communications, imaging and computing.

Many antennas, multiple benefits: Can handle cellular traffic more reliably Posted: 20 Jan 2015 05:45 AM PST A concept that balances large-scale installations of low-cost and low-power antennas to boost cellular coverage in difficult environments will also provide better connectivity to more users. This new architecture for wireless communications can help service providers meet growing demands for increased network capacity and improved energy efficiency.

Mathematical model that learns to compensate for positioning errors can control a micromanipulation system more accurately Posted: 20 Jan 2015 05:45 AM PST A mathematical model can improve the accuracy and repeatability of a positioning system by learning to anticipate tiny errors in its movements. Micromanipulation systems are used to control objects' positions with exquisite precision and play a vital role in applications such as telescopes and laser communication.
