Explainer: What is the electric grid?
Most of us get electricity through a huge system of power lines and equipment that together are known as the electric grid. Here’s how it works.
- Tech
New eyewear could help the visually impaired
Young inventors develop novel electronics to help people identify colors and navigate obstacles.
- Computing
Fingerprints could help keep kids from dangerous websites
A teen develops a program that estimates age based on someone’s fingers

Explainer: Seismic waves come in different ‘flavors’
Earthquakes generate several different types of seismic waves, some more damaging than others
- Physics
Explainer: Quantum is the world of the super small

Disabilities don’t stop these experts in science and tech
People with disabilities are as varied as the careers some of them pursue in science, technology, engineering and math.
- Chemistry
Scientists Say: Photochromic
Photochromic chemicals change shape when exposed to a specific wavelength of light. The shape change changes the chemical’s color.
- Physics
Scientists Say: Acoustic
Acoustic is an adjective used to describe something involving sound. It’s also a noun that refers to the branch of physics that studies sound.
