Fairy tale inspiration could help rovers explore risky places
Taking a cue from Hansel and Gretel, scientists propose a way for rovers to send back data from treacherous terrain.
- Environment
Fungi help rescue crops being harmed by microplastics
Microplastics in the soil hinder plant growth. But two finalists at Regeneron ISEF found that fungi and farm waste can reduce the harm.

Older diesel school buses linked to more student absences
Schools that replaced or upgraded old diesel school buses increased student attendance rates, new research shows.
- Tech
A new solar-powered gel purifies water in a flash
The unusual, fruit-inspired structure of this material provides quick filtration that could satisfy people's daily water needs.
- Tech
Magnetic fields melt and re-form new shape-shifting devices
Miniature machines made of gallium and magnetic particles can switch from solid to liquid and back.
- Chemistry
Chemists have unlocked the secrets of long-lasting Roman concrete
By searching ancient texts and ruins, scientists found a concrete recipe that could make buildings stronger — and help address climate change.

Here’s how to increase clean energy without harming wildlife
Wind farms, solar panels and more take up land and may harm wildlife. Researchers are working to resolve this conflict.
- Physics
A powerful laser can control the paths that lightning takes
In a mountaintop experiment, a laser beamed at the sky created a virtual lightning rod that snagged several bolts.
