Quantum interference of sodium nanoparticles, which can each contain more than 7,000 atoms at masses greater than 170,000 Da, is demonstrated.

With its attribution to Paranthropus, a 2.6-million-year-old partial mandible expands the range of the genus into the Afar region of Ethiopia and adds to our understanding of hominin evolution in eastern Africa.

Quantum technologies, systems that process, transfer or store information leveraging quantum mechanical effects, could tackle some real-world problems faster and more effectively than their classical counterparts. In recent years, some engineers have been foc…

A remote fossil site has revealed the largest dinosaur footprints ever documented, massive enough to dwarf a grown adult.

When Neanderthals in Italy were crossing the Alps, it's likely they took refuge in high-altitude bear caves. A new study of stone tools in Caverna Generosa, a cave sitting 1,450 meters up in the mountains, found that these travelers also brought a toolkit wit…

A pair of incredible images show the very moment that two different stars exploded, an incredible display that's melting our minds.

The Large Magellanic Cloud, or LMC, is a key spot for astronomers to study star formation.

Team aims to drill half-mile down into warming waters to gauge melt

In a recent study, researchers from China have developed a chip-scale LiDAR system that mimics the human eye's foveation by dynamically concentrating high-resolution sensing on regions of interest (ROIs) while maintaining broad awareness across the full field…

<p><em>Astronomers have observed the effects of a rapidly spinning black hole twisting the motion of matter around it, a result widely interpreted by cosmologists as consistent with a century-old prediction of Einstein’s general theory of relativity. The find…

Our planet has experienced dramatic climate shifts throughout its history, oscillating between freezing "icehouse" periods and warm "greenhouse" states.

A massive geological rift is tearing one of Earth’s largest continents in two, faster than scientists once believed.

In a landmark discovery that bridges nearly a century of theoretical physics, a Chinese research team has successfully captured the first direct evidence of the Migdal effect, a breakthrough with profound implications for probing dark matter—the invisible sub…

Along with bonus stargazing targets!

This close orbit subjects the planet to continuous stellar bombardment, turning its atmosphere into a furnace of volatile activity.

A strange set of magnetic fossils from the age of dinosaurs is making scientists wonder: did an extinct marine animal once navigate using Earth’s magnetic field?

Ars checks in with the new president of the Giant Magellan Telescope.

Gold, long considered untouchable, has revealed a hidden side in a lab experiment that could upend chemistry, energy science, and everything we thought we knew about the periodic table.

Mock observations test the performance of the Chinese Space Station Telescope as the 2-meter-class observatory moves closer to launch.

Shortly after its perihelion passage on October 29, 2025, the interstellar object 3I/ATLAS was imaged by amateur astronomers to have…

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the observation that matter behaves differently at the smallest scales. A key finding was wave-particle duality, the revelation that parti…

Ancient shoreline features hint that water on Mars once formed a vast ocean.

A novel biochemical analysis of a Renaissance medical text has successfully recovered centuries-old proteins that might be from lizards and hippos.

A paper proposes that outer space acts like viscous fluid, which if true could explain discrepancies in observations of the universe.

The unique bronze-and-gold Nebra Sky Disc appears to represent what the night sky looked like more than three millennia ago.
