Physicists create tabletop antimatter 'gun'

(Phys.org) —An international team of physicists working at the University of Michigan has succeeded in building a tabletop antimatter "gun" capable of spewing short bursts of positrons. In their paper published in the journal ...

Regular Light Bulbs Made Super-Efficient with Ultra-Fast Laser

(PhysOrg.com) -- An ultra-powerful laser can turn regular incandescent light bulbs into power-sippers, say optics researchers at the University of Rochester. The process could make a light as bright as a 100-watt bulb consume ...

Electrons at the speed limit

Electronic components have become faster and faster over the years, thus making powerful computers and other technologies possible. Researchers at ETH Zurich have now investigated how fast electrons can ultimately be controlled ...

Scientists create metal that pumps liquid uphill

(PhysOrg.com) -- In nature, trees pull vast amounts of water from their roots up to their leaves hundreds of feet above the ground through capillary action, but now scientists at the University of Rochester have created a ...

Laser-based camera can see around corners

(PhysOrg.com) -- Researchers from MIT have developed a camera that can capture images of a scene that is not in its direct line of sight. The camera is equipped with a femtosecond laser, which fires extremely short bursts ...

3D laser printing yields high quality micro-optics

Researchers have demonstrated 3D printing of micron-scale optics with unprecedented performance and reproducibility. Their approach can be used to create almost any type of integrated optical element on a micron or smaller ...

Laser Fusion and Exawatt Lasers

(PhysOrg.com) -- In the recent past, producing lasers with terawatt (a trillion watts) beams was impressive. Now petawatt (a thousand trillion watts, or 10^15 watts) lasers are the forefront of laser research. Some labs are ...
