Your running speed partly comes down to factors you can't control, like genetics, and partly relies on your training. | Continue reading
How can we truly know if AI is sentient? We do not yet fully understand the nature of human consciousness, so we cannot discount the possibility that today's AI is indeed sentient — and that we are mistreating it to potentially grave consequences. | Continue reading

New James Webb Space Telescope observations of the exoplanet WASP-43b reveal that the hot gas giant is tidally locked, meaning one side permanently faces its sun while the other always stares out into space. | Continue reading
The wreck near a beach on Mallorca gives a snapshot of sea trade in late Roman times. | Continue reading
Flaring stars, black hole outbursts and gamma-rays are just some of the cosmic exotica that Einstein Probe will hunt for. | Continue reading
The Cave of Crystals in Chihuahua, Mexico, is buried almost 1,000 feet (300 meters) beneath Earth's surface and contains giant gypsum crystal beams that are up to 37 feet (11 m) long. | Continue reading
Mercury is about to reach its "greatest elongation west" of the sun, meaning stargazers will have their best view of the "swift planet" all year. Here's how to see it. | Continue reading
A new type of hybrid sodium-ion battery that offers both high capacity and rapid-charging capabilities could power mobile devices, electric vehicles and space tech. | Continue reading
Climate models can be a million lines of code long and can take months to run on supercomputers. A new algorithm has dramatically shortened that time. | Continue reading
The James Webb Space Telescope's possible detection of biological chemicals on the exoplanet K2-18b may just have been methane gas, a new study cautions. Planned follow-up observations could solve the mystery for good. | Continue reading
Read about the latest news, incredible discoveries and mind-bending advances in science by following us on social media. | Continue reading
Scientists built a "smart filter" that can work with a cheap smartphone camera to transform low-resolution photos into supersharp images without glare and other issues. | Continue reading
With her long, brown hair and determined gaze, the new facial reconstruction lets us peek into the world of an archaic human who lived tens of thousands of years ago. | Continue reading
A pair of odd twisters spun out from a supercell thunderstorm in Oklahoma Tuesday (April 30). | Continue reading
Scientists have calculated the rotational speed of asteroid 2024 BX1, which exploded over Berlin earlier this year, by letting it trail in images of the sky. It turns out, 2024 BX1 was spinning faster than any other near-Earth object ever seen. | Continue reading
Fears of electric vehicle fires are blown out of proportion, but because EVs are heavier on average, they're safer for passengers but more dangerous for non-occupants, studies suggest. | Continue reading
Huge "tiger stripe" fault lines seen on Saturn's moon Enceladus raise hopes that a "long-lived" ocean containing potential alien life may lurk beneath the moon's icy shell. | Continue reading
A study of mice starts to unravel how the brain gets tricked by this kind of optical illusion, and it gives clues about how visual perception works. | Continue reading
Scientists build the world's first 6G antenna that, when fitted into devices, can transmit data at high speeds. | Continue reading
The sword is the first weapon from the Islamic period to be found in the Spanish city of Valencia. | Continue reading
Submillimeter wavelength radio observations of the Southern Ring Nebula have identified that it's actually a double ring, shaped by the interactions of three stars. | Continue reading
Mars has had frequent planet-wide auroras in recent months, including an unprecedented trio of events in February. Experts say the sudden increase is the result of the ongoing solar maximum. | Continue reading
A new map of a brain network that sustains wakefulness in humans could help improve our understanding of consciousness. | Continue reading
A new imaging technique, which captured frozen lithium atoms transforming into quantum waves, could be used to probe some of the most poorly understood aspects of the quantum world. | Continue reading
Northrop Grumman Corporation has built its Manta Ray uncrewed underwater vehicle, which will operate long-duration missions and carry payloads into the ocean depths in partnership with DARPA. | Continue reading
Up to 50 "shooting stars" per hour may be visible in moonless skies as the Eta Aquarid meteor shower peaks Saturday and Sunday (May 4 and 5). The annual shower is linked to debris from Halley's comet. | Continue reading
In recent experiments, rat brain cells filled in for lost neurons in mouse brains, raising new possibilities for growing donor tissues across species. | Continue reading
Researchers say a villa buried by the eruption in A.D. 79 corresponds with records of the Roman emperor's death in A.D. 14. | Continue reading
Prehistoric cold viruses are hard to find in the historical record, but scientists have unearthed some evidence in ancient human teeth. | Continue reading
Scientists have detected a new, unusually large molecule never seen in space before. The 13-atom molecule, called 2-methoxyethanol, was detected in the Cat's Paw Nebula. | Continue reading
Doctors say it's very unusual to develop a visual impairment as the first symptom of lung cancer. | Continue reading
Captured in infrared light by the James Webb Space Telescope, the star-forming Horsehead Nebula is located 1,300 light-years away in the Orion Constellation. | Continue reading
Chinese astronomers have shared the most detailed geological map of the moon ever created, revealing more than 12,000 structures. The new atlas will be essential for picking out landing locations and resource sites for future lunar missions. | Continue reading
Arabica coffee plant appears to have evolved between 600,000 and 1 million years ago after two other coffee species crossbred in the forests of what is now Ethiopia. | Continue reading
Scientists in Japan have transferred data at 100 gigabits per second in high-frequency wavelength bands over a distance of 330 feet for the first time. | Continue reading
Supermassive black holes may create conditions akin to "cosmic intersections with failed traffic lights" that make collisions between smaller stellar-mass black holes inevitable. | Continue reading
