New gamma-ray observatory begins operations at Sierra Negra volcano
The High-Altitude Water Cherenkov (HAWC) Gamma Ray Observatory has begun formal operations at its site in Mexico. HAWC is designed to study the origin of very high-energy cosmic rays and observe the most ...
How to prevent earthquake damage: make buildings invisible
Bell Labs researchers build camera with no lens
New design for a metamaterial could be far more efficient at capturing sunlight than existing solar cells
Metamaterials are a new class of artificial substances with properties unlike anything found in the natural world. Some have been designed to act as invisibility cloaks; others as superlenses, antenna systems ...
Cantilever bends repeatedly under light exposure for continuous energy generation
An ultrasensitive molybdenum-based image sensor
A new material has the potential to improve the sensitivity of photographic image sensors by a factor of five. In 2011, an EPFL team led by Andras Kis discovered the amazing semi-conducting properties of ...
Single-pixel power: Scientists make 3-D images without a camera
Their system uses simple, cheap detectors which have just a single pixel to sense light instead of the millions of pixels used in the imaging sensors of digital cameras.
