The downfall of a long-standing theory in psychology raises a question: How much does the environment we’re raised in change how we literally see the world?

A new analysis uncovers seasonal patterns of dengue, a mosquito-borne disease, across the Americas, which could help scientists anticipate future outbreaks

Astronomers have spotted what could be the brightest Fast Radio Burst explosion of radiation ever, tracing it back to source and further investigating with the James Webb Space Telescope.

The Canon EOS R8 is now $383 off and comes with a wide-angle zoom lens. Now is a good time to buy, too, with the galactic core of the Milky Way still visible — but not for too much longer!

A quantum computer that uses particles of light took about two dozen microseconds to complete a calculation that may take trillions of trillions of trillions of years on the world’s best supercomputers

Money talks louder in some languages than others

This powerful side-by-side comparison shows just how bright a star explosion is.

Researchers spied a wild array of life, including dozens of suspected new species, in an underwater gorge

It's back to the Wasteland for more nuked nightmares when Prime Video's hit sci-fi series returns in December.

The 60-meter asteroid 2024 YR4 has a 4 percent chance of hitting the moon. Could such a lunar collision create a dangerous new meteor shower?

Peanut allergies more than tripled in U.S. kids between the late 1990s and late 2000s, and the prevalence has risen even more since then. Scientists are still searching for answers—and new ways to treat them.

The impending merger of the two galaxies hints at what might be in store for the Milky Way and the Andromeda galaxy if and when they collide.

The Kite of Boötes tips. The Great Square of Pegasus balances en pointe. Cassiopeia climbs. And Saturn muscles up in the east.

The camera battery died about 2am local time

The U.S. Space Force's X-37B space plane lifted off atop a SpaceX Falcon 9 rocket tonight (Aug. 21), carrying a variety of high-tech gear to Earth orbit.

Exoplanets with and without a magnetic field are predicted to form, behave, and evolve very differently. In order to understand the exoplanet population, and to make progress understanding habitability, astronomers need to understand and constrain exoplanets' magnetic fields. Detecting them may best be done from the Moon.

Physicists from the University of Copenhagen have begun using the gigantic magnetic fields of galaxy clusters to observe distant black holes in their search for an elusive particle that has stumped scientists for decades.
