A device spots and counts honeybees hosting a dangerous parasite
At Regeneron ISEF, three teens debuted an infrared system to detect honeybees carrying mites. It can show beekeepers when a colony needs to be treated.

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.

Let’s learn about piezoelectric materials
Piezoelectric materials turn mechanical energy into electrical energy — and vice versa.
- Computing
A single chip like this could transmit a world’s worth of data
The internet has a big environmental footprint. But this new type of tech could help reduce the climate impact of computing.

When it comes to dance, it’s all about the bass
During a concert, people danced more when they were bathed in sounds that were too low for their ears to hear.
