Waves and Their Applications in Technologies for Information Transfer
- Earth
Explainer: Earth — layer by layer
Explore the sizzling heat, unimaginable pressures — and some surprise diamonds — that sit beneath our feet. This is the side of Earth that you can’t see.
- Health & Medicine
Explainer: What is ultrasound?
These sound waves, which fall above the range of human hearing, are important in medicine, medical imaging and more.
- Tech
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
- Science & Society

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
The word quantum often gets misused. What does it mean? Think small. Really, really 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.
