NASA to demonstrate communications via laser beam

It currently takes 90 minutes to transmit high-resolution images from Mars, but NASA would like to dramatically reduce that time to just minutes. A new optical communications system that NASA plans to demonstrate in 2016 ...

Whales as ecosystem engineers

"Consider the subtleness of the sea; how its most dreaded creatures glide under water, unapparent for the most part," wrote Herman Melville in Moby Dick. Today, we no longer dread whales, but their subtlety remains. "For ...

Could plasma jet thrusters 'kickstart' interplanetary travel?

A great offshoot from commercial space companies getting a foothold in real missions to orbit is that the old entrepreneurial space spirit seems to have been revived. People are attempting to develop and build what could ...

Wireless power transfer enhanced by metamaterials

(Phys.org)—Over the past decade, research on wireless power transfer has led to the development of several commercial applications, such as wireless charging of mobile devices and electric toothbrushes, as well as wireless ...

Nano-LEDs emit full visible spectrum of light

(PhysOrg.com) -- Physicists from Taiwan have designed and fabricated nano-sized light-emitting diodes (LEDs) that emit light spanning the entire visible spectrum. Although the tiny full-color LEDs aren't intended for commercial ...

Smart material prototype challenges Newton's laws of motion

For more than 10 years, Guoliang Huang, the Huber and Helen Croft Chair in Engineering at the University of Missouri, has been investigating the unconventional properties of "metamaterials"—an artificial material that exhibits ...
