Engineers break power and distance barriers for fiber optic communication
Electrical engineers have broken key barriers that limit the distance information can travel in fiber optic cables and still be accurately deciphered by a receiver. Photonics researchers at the University of California, San ...

Interplanetary precision laser could reach to Mars and beyond
(Phys.org) —Currently, precision laser ranging is limited to the Earth-Moon distance. These systems are based on passive laser ranging, so that the signal deteriorates as 1/R4 over distance R. In a new study, physicists ...
The Internet comes to you across the bottom of the ocean
The Internet brings you data from around the world almost instantly. This information, coming from Geneva or Tokyo or Buenos Aires, arrives in the U.S. not from satellite but along cables that sit on the bottom of the ocean. ...

Physicists use a 350-year-old theorem to reveal new properties of light waves
Since the 17th century, when Isaac Newton and Christiaan Huygens first debated the nature of light, scientists have been puzzling over whether light is best viewed as a wave or a particle—or perhaps, at the quantum level, ...

Astronomy team finds evidence of galactic metal shrouded in dust
A thorough understanding of galaxy evolution depends in part on an accurate measurement of the abundance of metals in the intergalactic medium—the space between stars—but dust can impede observations in optical wavelengths. ...
