Improving lasers with microring mirrors

(PhysOrg.com) -- We use lasers everyday, though many of us may not think about it. “Lasers are in a number of consumer products,” Lynford Goddard tells PhysOrg.com. “We have them in DVD players, printers, and ...

New type of solar structure cools buildings in full sunlight

(Phys.org) —A Stanford team has designed an entirely new form of cooling panel that works even when the sun is shining. Such a panel could vastly improve the daylight cooling of buildings, cars and other structures by radiating ...

Lost Reflector Found on the Moon

Physicists have pinpointed the location of a long lost light reflector left on the Moon by the Soviet Union nearly 40 years ago. The reflector could actually help today's scientists measure physical properties of the Moon ...

Laser beams reflected between Earth and moon boost science

Dozens of times over the last decade NASA scientists have launched laser beams at a reflector the size of a paperback novel about 240,000 miles (385,000 kilometers) away from Earth. They announced today, in collaboration ...

Acoustic levitation made simple

A team of researchers at the University of São Paulo in Brazil has developed a new levitation device that can hover a tiny object with more control than any instrument that has come before.

Fossil moths show their true colors

The brightest hues in nature are produced by tiny patterns in, say, feathers or scales rather than pigments. These so-called "structural colors" are widespread, giving opals their fire, people their blue eyes, and peacocks ...
