President Trump has argued the U.S. should test nuclear weapons because other countries are doing it. But scientific data suggest they’re not.

New evidence may resolve a longstanding archaeological puzzle in Peru. A vast line of thousands of holes dug into a ridge in the foothills of the Andes Mountains served as a regional marketplace for pre-Inca groups more than…

If you have ever been awake late at night and heard a strange, high-pitched scream echoing through the darkness, you might have wondered what it was. Many people describe it as frightening, almost human-like but it’s often the sound of a…

You all must have heard the rhythmic tick-tick sound of a clock in a quiet room, have you ever sat and thought about it, why does it happen? The answer lies in the simple science of how clocks keep time. The tick-tick sound comes from the…

The jewels nabbed in the Louvre heist may still be at large, but scientists have just closed the case on another gemstone mystery: what gives rare ammolite gems their rainbow shimmer. Ammolite comes from the fossilized shells…

From growing smaller leaves to shape-shifting its insides, a desert flowering plant goes all in to flourish in the harshest of conditions. Summer temperatures in Death Valley National Park frequently exceed 50° Celsius (122°…

China’s Tianwen 1 spacecraft has captured new images of the interstellar comet 3I/ATLAS. The China National Space Administration (CNSA) released the pictures this week, noting that these were taken between October 1 and October 4.…

Studying winds on Mars is very difficult. On Earth, we can easily use weather balloons or satellite tools to measure wind directly. But on Mars, there are very few places where scientists can put instruments — and the air on Mars is…

Hidden beneath all their rum-pum-pumming, woodpeckers are quietly grunt-grunt-grunting. The birds exhale with each strike, much like a tennis pro groaning through a stroke. Elaborate coordination between those breaths and…

Streams of liquid form drops thanks to unidentified disturbances. It could be the jiggling of individual molecules.

Planetary scientist Adeene Denton runs computer simulations to investigate Pluto, the moons of Saturn and other icy bodies in the solar system.

Math and physics explain the anguish of a golf ball that zings around the rim of the hole instead of falling in.

Supernova remnants, stellar nurseries and more populate the new edge-on view of the Milky Way as seen from Earth’s southern hemisphere.

Iceland’s first mosquitoes are poised to face a frosty test. Winter is coming, and it’s uncertain whether these newcomers might stick around until spring. The Nordic island, previously one of the last places on Earth without…

When a person is trapped in an avalanche, there is very little time before their oxygen supply runs out. A new safety device that channels air to the buried person’s face may extend survival and increase the chance of a…

An AI tool trained on chemical signatures from corpse-eating insects may help determine time and place of death for victims of violent crimes.

Meghan Rosen is a senior writer who reports on the life sciences for Science News. She earned a Ph.D. in biochemistry and molecular biology with an emphasis in biotechnology from the University of California, Davis, and later…

A new Nanotyrannus fossil suggests the diminutive dino lived alongside T. rex in the late Cretaceous Period

A Japanese flower lures in its pollinators with a morbid perfume — the scent of injured ants. The unusual scent belongs to Vincetoxicum nakaianum, a recently named species of Japanese dogsbane. Botanist Ko Mochizuki of the…

New Delhi: The interstellar comet 3I/ATLAS is set to reach its closest point to the Sun which is called the perihelion  at a distance of 1.35 astronomical units, or about 125 million miles (202 million kilometres).   (This is a breaking…

Some planets might produce their own water instead of relying on outside sources. In laboratory experiments, researchers simulated extreme conditions found within certain exoplanets by blasting olivine — a mineral abundant in…

Theoretical physicist Alex Lupsasca is pushing for a space telescope to glimpse the thin ring of light that is thought to surround every black hole.

Scientists found thousands of patterned fish nests in Antarctica’s Weddell Sea, boosting calls for marine protected areas.

Two small genetic changes reshaped the human pelvis, setting our early ancestors on the path to upright walking, scientists say. One genetic change flipped the ilium — the bone your hands rest on when you put them on your hips…

A new AI model is opening the black box of the leading artificial intelligence tool for predicting how proteins will interact with small molecules, such as drugs. The model, OpenFold3, which launched October 28, is a…

With winds whirling at about 290 kilometers per hour, Hurricane Melissa is one of the strongest ever recorded in the Atlantic Ocean — and is poised to become the strongest storm ever to make landfall in Jamaica. It’s also a…

In a single year, one polar bear can leave roughly 300 kilograms of prey for other animals to dine on. Altogether, the carnivores provide 7.6 million kilograms of carrion for scavengers throughout the Arctic, researchers estimate.…

A fossil unearthed on Eastern Europe’s Crimean Peninsula has divulged the strongest genetic clues yet about Neandertals’ long-distance journeys into the heart of Asia. After identifying a bone fragment previously excavated…
