(PhysOrg.com) -- Physicists Praveen Ashok, Bavishna Praveen, and K. Dholakia working together at the University of St Andrews in Scotland have developed a method for testing whiskey for authenticity using a crafted device that allows for measurements via spectroscopy.

A new report warns that the exploding usage of radio waves by broadband-devouring smartphones and video threatens to deplete a finite wireless spectrum . “If you look at traffic patterns over the past five years, we went from things like illegal music downloads, to legal music downloads, to video,” said technology adviser and report author Michael Kleeman at University of California San Diego

It can take a bit more than a 30-second elevator pitch to understand Kaggle , a new Silicon Valley startup founded by 28-year-old Australian Anthony Goldbloom. After all, it's not selling anything, creating another social network, or peddling yet another useless app

An international research team led by the University at Buffalo has shown that large energy fluctuations can rile even a "relaxed" system, raising questions about how energy might travel through structures ranging from the ocean to DNA.

Aiming to take "clean" to a whole new level, researchers at the University of California at Berkeley and the University of Maryland at College Park have teamed up to study how low-temperature plasmas can deactivate potentially dangerous biomolecules left behind by conventional sterilization methods. Using low-temperature plasmas is a promising technique for sterilization and deactivation of surgical instruments and medical devices, but the researchers say its effectiveness isn't fully understood yet.

When digital cameras focus, they use a complicated and slow system that often doesn't come close to being correct. Humans, however, focus correctly in an instant.

Many physicists are great at figuring out how the world works, but less adept at describing those workings to a nontechnical audience.

(PhysOrg.com) -- Engineering researchers at the University of Toronto have developed the world's most efficient organic light-emitting diodes (OLEDs) on plastic. This result enables a flexible form factor, not to mention a less costly, alternative to traditional OLED manufacturing, which currently relies on rigid glass.
