Physicists have long relied on the idea that electrons behave like tiny particles zipping through materials, even though ...

Several years ago, scientists discovered that a single microscopic particle could rock back and forth on its own under a ...

Columnist Natalie Wolchover checks in with particle physicists more than a decade after the field entered a profound crisis.

In its first moments, the infant universe was a trillion-degree-hot soup of quarks and gluons. These elementary particles ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

Astronomers found evidence that dark matter and neutrinos may interact, hinting at a "fundamental breakthrough" that ...

It’s a fundamental principle of physics that particles with opposite charges attract each other, while those with the same charge repel. But now, scientists at the University of Oxford have found that ...

But only in the last 70 years have we known for certain they were there. In 1956, physicists Clyde Cowan and Frederick Reines ...

Far beneath the Antarctic ice sheet, scientists are mapping a landscape that looks less like a frozen desert and more like an ...

The use of atomic clocks could help bring cosmology and astrophysics "down to Earth" by allowing scientists to investigate the mysteries of dark energy and dark matter in the lab. When you purchase ...
