Tech

Scientists Say: Prototype

These rough draft models help engineers test how a concept translates from theory to reality.

Physics

Here’s how rainwater might one day power some of your lights

In tests, the electricity that water droplets made was small, but kept a dozen LEDs lit. This tech might one day power clean energy for wet or rainy places.

Animals

These fish yawn — and it’s contagious

Zebrafish are the first cold-blooded animals known to behave this way. Contagious yawning may affect other behaviors in these fish, too.

Artificial Intelligence

This researcher investigates the risks of digitally cloning the dead  

Katarzyna Nowaczyk-Basińska investigates the risk of AI-driven grief bots — while commuting between Poland and England.

Space

Scientists Say: Quasi-satellite

Unlike a true satellite, these tagalongs orbit outside a planet’s primary sphere of gravitational control.

Tech

This 3-D printed robot runs on air, not electricity

The soft, flexible robot can cover uneven ground and even walk underwater.

Environment

New ocean sanctuaries house young coral and even flee peril

Two ISEF finalists want to foster growth of new coral reefs. So these teens designed and built self-navigating, undersea houseboats for coral larvae.

Tech

This squirrel-like robot has some serious hops

Salto the jumping robot has a claw-like gripper. Like a squirrel, it can adjust its movement to help it stay balanced to stick a landing on "branches."

Life

Research without lab animals? New tech is making it possible

For decades, scientists have worked to phase out the use of animals in research. AI, ‘lungs’ on a chip and more are bringing that goal closer.

Tech

You can ‘grab’ these virtual displays and manipulate them midair

Such interactive floating graphics and virtual objects could be used to make more immersive video games and museum exhibits.

Tech

Soft helpers and bio-inspired tech: a match made in robot heaven

Hugging toys offer emotional support to anxious kids and slithering snake-like robots may bring rescue aid to people trapped in dangerous conditions.
