NASA small satellites can aid hurricane forecasts with GPS

Eight briefcase-size satellites flying in a row may be key to improving forecasts of a hurricane's wind speed—detecting whether it will make landfall as a Category 1 or a Category 5. NASA's Cyclone Global Navigation Satellite ...

Team shows atoms can receive common communications signals

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a new type of sensor that uses atoms to receive commonly used communications signals. This atom-based receiver has the potential to ...

Scientists design new material to harness power of light

Scientists have long known that synthetic materials—called metamaterials—can manipulate electromagnetic waves such as visible light to make them behave in ways that cannot be found in nature. That has led to breakthroughs ...

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 ...

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.
