Materials of the last century shaped modern life, but at a price
From our homes and cities to our electronics and clothing, the stuff of daily life is dramatically different from decades ago.
- Physics
An ‘everlasting’ bubble endured more than a year without popping
One of the bubbles, made with water, glycerol and microparticles, lasted 465 days before popping.
- Quantum Physics
Quantum particles can feel the influence of gravitational fields they never touch
A quantum phenomenon predicted in 1959, the Aharonov-Bohm effect, also applies to gravity.
- Quantum Physics
A century of quantum mechanics questions the fundamental nature of reality
A century after the quantum revolution, a lot of uncertainty remains.
- Physics
Antiprotons show no hint of unexpected matter-antimatter differences
The ratio of electric charge to mass for protons mirrors that of their antimatter counterparts.
- Quantum Physics
Quantum physics requires imaginary numbers to explain reality
Quantum theory based only on real numbers fails to explain the results of two new experiments.
- Astronomy
The only known pulsar duo sheds new light on general relativity and more
Einstein was right, among other insights gleaned from watching a one-of-a-kind system of two pulsating dead stars for 16 years.
- Health & Medicine
For 50 years, CT scans have saved lives, revealed beauty and more
In 1971, the first CT scan of a patient laid bare the human brain. That was just the beginning of a whole new way to view human anatomy.
- Quantum Physics
Physicists have coaxed ultracold atoms into an elusive form of quantum matter
Quantum spin liquids could be used to help protect fragile information in quantum computers.
- Quantum Physics
Scientists finally detected a quantum effect that blocks atoms from scattering light
When all available quantum states are full, atoms can’t scatter light, thanks to the Pauli exclusion principle, new experiments show.

This eco-friendly glitter gets its color from plants, not plastic
Using cellulose extracted from wood pulp, researchers have created a greener alternative to traditional glitter.
