LCDs get brighter with nano polarization recycler

LCDs (liquid crystal displays) provide a popular method for lighting screens on everything from computers and TVs to watches, clocks, cell phones and more. However, as scientists Sang Hoon Kim, Joo-Do Park and Ki-Dong Lee ...

Sterile neutrinos and the search for warm dark matter

Matteo Viel, a research fellow at the Institute of Astronomy in Cambridge, England, believes that particle physics and cosmology could be more compatible as scientists work toward understanding the origins and the nature ...

Snakes’ heat vision enables accurate attacks on prey

Call it a sixth sense, or evolution’s gift to these cold-blooded reptiles: some snakes have infrared vision. Also called “heat vision,” the infrared rays, which have longer wavelengths than those of visible light, signify ...

Scientists turn dents into smart bumps

Due to a phenomenon called the shape memory effect (SME), certain "memory metals" can be distorted and then brought back to their original shape by a simple temperature change. While a one-way memory effect has inspired applications ...

Scientists explain causes of abrupt rain storms

No two rain storms are alike. Dark clouds may form slowly throughout the day before a drop of rain falls, and sunny days can suddenly transform into thunderstorms. Different societies throughout history have held their own ...

Detector can count atom by atom

More than 80 years have passed since Louis de Broglie discovered that matter can act like a wave as well as a particle. With advances in technology, scientists have recently begun exploiting this strange property of everyday ...
