Engineer aims to connect the world with ant-sized radios

(Phys.org) —A Stanford engineering team has built a radio the size of an ant, a device so energy efficient that it gathers all the power it needs from the same electromagnetic waves that carry signals to its receiving antenna ...

ASKAP test finds "monster" black hole

Imagine trying on new pair of spectacles and when glancing around to test them you spot a monster—that's exactly what happened when the ASKAP antennas were turned towards a group of three merging galaxies 1.8 billion light ...

New antenna spreads good vibrations in fusion plasma

If you want to catch a firefly, any old glass jar will do. But when you're trying to bottle a star—the goal of fusion energy research—the bottle needs to be very special. A tokamak is one type of fusion bottle, capable ...

Low-power Wi-Fi signal tracks movement—even behind walls

The comic-book hero Superman uses his X-ray vision to spot bad guys lurking behind walls and other objects. Now we could all have X-ray vision, thanks to researchers at MIT's Computer Science and Artificial Intelligence Laboratory.

Best view yet of merging galaxies in distant universe

Using the Atacama Large Millimeter/submillimeter Array, and other telescopes, an international team of astronomers has obtained the best view yet of a collision that took place between two galaxies when the Universe was half ...

Chu's Limit—a limit no more

Chu's Limit, a fundamental principle of electromagnetics, dictates that the bandwidth an antenna can function in has a maximum level proportional to the physical size of the antenna—the smaller the antenna, the smaller ...

Solar cell efficiency could double with novel 'green' antenna

The use of solar energy in the U.S. is growing, but panels on rooftops are still a rare sight. They cost thousands of dollars, and homeowners don't recoup costs for years even in the sunniest or best-subsidized locales. But ...

Ultrafast technique unlocks design principles of quantum biology

University of Chicago researchers have created a synthetic compound that mimics the complex quantum dynamics observed in photosynthesis and may enable fundamentally new routes to creating solar-energy technologies. Engineering ...
