Radar technologies were originally designed to identify and track airborne military targets. Today, they're more often used to detect motor vehicles, weather formations, and geological terrain. Until now, scientists believed that radar accuracy and resolution are related to the...

Researchers have developed a more efficient, more reliable potassium-oxygen battery with a cathode that stores the energy produced by a chemical reaction in a metal-oxygen or metal-air battery. The battery could make renewable energy sources like solar and wind more viable options for the power grid...

This method also reverse-engineers computer chips to detect the chip’s purpose.

These polymers can combine thermal and optically fixable shape memory.

Squid skin inspires a new material with heat-regulating properties.

When combined with saltwater, rust can be a source of electricity.

A simple modification can improve the capability of turbulent heat exchangers by 500%.

The device could impact composites manufacturing and health monitoring.

A team at MIT created self-assembling robotic cubes that can climb and roll over each other into set formations.

Increasingly, lithium-ion batteries are supporting portable electronics, electric vehicles, and grid storage.

A preventive treatment developed by Stanford researchers could greatly reduce the incidence and severity of wildfires. The cellulose-based, gel-like fluid protects against fires and stays on target vegetation through rain, wind, and other environmental exposure. Watch the demo on Tech Briefs TV.
