Climate change, nuclear arms control, the pandemic and more will be determined by whoever wins the White House and Congress.

Some physicists claim the popular landscape of universes in string theory may not exist.

The natural world is the only world, theoretical physicist Sean Carroll argues in a new book.

High-profile physicists and philosophers gathered to debate whether we are real or virtual — and what it means either way.

The Large Hadron Collider particle accelerator failed to confirm the Tevatron accelerator’s discovery of a new arrangement of quarks.

Data from the DZero experiment shows evidence of a particle containing four different types of quarks.

The most precise measurement yet of the electron’s shape casts doubt on ideas such as supersymmetry that predict a zoo of undetected particles in the universe

The Fitbit Flex was my constant companion for about a week, and by the end of it, I was pretty fond of the device.

After a week wearing the Jawbone Up, I was pretty impressed with this nifty device.

Slinking along through the sands of space is a "cosmic caterpillar" as dubbed by NASA in a new photo released from the Hubble Space Telescope.

The Milky Way's giant black hole turns out to be a messy eater. Of all the gas that falls toward it, 99 percent gets spewed back out into space, new observations show.

Astronomers have found a twin star to Earth's own sun, only much older. The rare star is the oldest known "solar twin," and offers a peek at what Earth's star will look like in 4 billion years.

Is there any more esoteric, almost mystical-sounding scientific field than particle physics?

Astronomers working with the Very Large Telescope in Chile plan to announce a "major result" Wednesday (Aug. 28).

Inside the Explorers Club are artifacts from over a century's worth of exploration, including narwhal tusks, a stuffed polar bear and even a whale penis.

The Explorers Club is open only to members who've sailed to new shores, climbed to new heights or trekked on new paths.

A strangely dense spot in the universe populated by a surprising amount of matter has been puzzling scientists since it was revealed in March in an all-sky map made by the European Planck satellite.

The speed of light is considered to be the ultimate cosmic speed limit, thanks to Einstein's special theory of relativity. But physicists aren't content to assume this limit without testing it.

Scientists have uncovered a new key to understanding the strange workings of neutron stars — objects so dense they pack the mass of multiple suns into a space smaller than a city.

Exotic particles called neutrinos have been caught in the act of shape shifting, switching from one flavor to another, in a discovery that could help solve the mystery of antimatter.

A giant radio telescope in Chile has captured amazing baby photos of what will eventually be a colossal star 11,000 light-years from Earth. Even more shocking: It's still growing, scientists say.
