Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have uncovered previously unobserved oscillation states—so-called Floquet states—in tiny magnetic vortices. Unlike earlier experiments, which required energy-intensive laser pulses to create such …

What if we told you that Mount Everest was once underwater? The discovery of marine fossils at its summit has scientists scratching their heads.

A new video provides a front-row seat to a cosmic drama that has been playing out for centuries.

Ceratopsians were horned, beaked dinosaurs that once stomped their way all over North America and Asia during the Late Cretaceous period, about 80 million years ago. Their abundance in the fossil records of these continents, which were connected by land bridg…

JWST peered at the glowing trail of stars left behind by a candidate runaway supermassive black hole deep in space, revealing new insights after other telescopes looked at the event.

Development continues on NASA’s Power and Propulsion Element, a solar electric propulsion spacecraft designed to provide power for Gateway in lunar orbit.

2025 MN45 is 0.4 miles wide and completes one rotation every 1.88 minutes.

A billionaire-backed philanthropic organization is funding the development of a series of new observatories, including a space telescope larger than Hubble.

Researchers have proposed a theoretical timepiece, dubbed the "CRASH Clock," which tells us how quickly satellites would start colliding if they lost the ability to avoid each other, such as during a powerful solar storm. And its value is rapidly decreasing.

Scientists at the University of Colorado Boulder may have solved a pressing mystery about the universe's gravitational wave background.

Flash forward 10 years and Sivakumar had become an integrative biology major paid to conduct groundbreaking research into how the genes of closely related bird species help cause the variation in the architecture of their wings.

Beneath one of the world’s busiest trade routes, a long-forgotten tectonic fault is stirring back to life. New scientific evidence reveals unexpected underground shifts in a region once declared geologically dead.

“Standing at the edge of the world, in a place I only knew from photos and documentaries, I can’t imagine a greater thrill than this,” she wrote in one account. “The thrill of seeking to know the ocean and joining the ranks of researchers across the globe wor…

After being preserved for millennia, the crocodile's stomach was recently scanned,and the results are jaw-dropping.

Cells experience many different types of stress, such as starvation or stress caused by too much salt or too high a temperature. Insulin signals respond to such stress signals by sending the protein DAF-16 into the cell nucleus where it activates the stress-s…

To ensure that the tissue structures of biological samples are easily recognizable under the electron microscope, they are treated with a staining agent. The standard staining agent for this is uranyl acetate. However, some laboratories are not allowed to use…

Solar system comets are often at their brightest as they draw close to the sun

Nearly everything in the universe is made of mysterious dark matter and dark energy, yet we can’t see either of them directly. Scientists are developing detectors so sensitive they can spot particle interactions that might occur once in years or even decades.…

They're called ghost particles for a reason. They're everywhere—trillions of them constantly stream through everything: our bodies, our planet, even the entire cosmos. These so-called neutrinos are elementary particles that are invisible, incredibly light, an…

Both NASA’s James Webb Space Telescope and Chandra X-ray Observatory caught these two galaxies in a close embrace.

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might behave slightly differently at extreme energies. By tracking ult…

The discovery that small stone arrow tips were treated with plant poison 60,000 years ago means that ancient African hunters were capable of complex thinking.

Experiments inside a fusion reactor in China have demonstrated a new way to circumvent one of the caps on the density of the superheated plasma swirling inside.

Fossilized bones and teeth dating to 773,000 years ago are providing a deeper understanding of the emergence of Homo sapiens.

Cold weather is vanishing—and with it, something vital inside the world’s crops. Scientists are uncovering how the loss of deep winter chill is quietly disrupting flowering, pest control, and even plant memory.
