A Chinese engineering student created sword-shaped drones controlled by hand gestures using a wrist-mounted sensor band that detects tilts and movements. The 2-foot 3D-printed quadcopters feature four tiny propellers embedded along their length and respond smoothly to hand motions, allowing users to guide them through the air like fantasy flying swords from martial arts films.
Researchers created a flexible skin patch that converts touch patterns into digital text using iontronic sensors and AI. The device recognizes all 128 ASCII characters and provides vibration feedback for screen-free communication.
Scientists are developing biocomputers using living human brain cells grown into clusters called organoids, which are connected to electrodes to perform computational tasks like playing Pong and recognizing speech patterns. These...
Scientists conducting deep-sea mining tests at 13,123 feet below the Pacific Ocean surface discovered numerous previously unknown species, including marine worms, crustaceans, and mollusks, while documenting that mining activity...
Astronomers have developed a new method using gravitationally lensed quasars to measure cosmic expansion, bypassing traditional distance ladder techniques. By analyzing time delays in light from eight quasar systems bent around...
Scientists found a "fire amoeba" in California that reproduces at 63°C, breaking temperature records for complex life. This discovery challenges survival limits and suggests biotechnology applications.

A severe global helium shortage has persisted for over a decade as demand skyrockets for MRI machines, quantum computers, and rockets, but scientists have recently discovered massive "carbon-free" helium reservoirs trapped in...
A programmer attempted to develop a mathematical framework for representing music using functional programming concepts, exploring various approaches including functions that map time to sets of notes with durations. While...
Japanese physicists propose that knotted structures formed in the early universe could explain why matter dominates over antimatter, solving a fundamental mystery about our existence. Their model combines two particle physics...
Lead nuclei show unexpected behavior that defies nuclear physics predictions, with spin-dependent effects from two-photon exchange mysteriously vanishing or appearing much larger than expected. This confirmed anomaly threatens...
The SPHERE instrument on ESO's Very Large Telescope captured extraordinary images of 51 debris disks around young stars, revealing dusty structures where planetesimals collide and create dust that shows where new planets are...
Scientists used neutron stars to search for a hypothetical fifth fundamental force by studying their cooling rates over millions of years. The normal cooling observed ruled out strong scalar-particle interactions, setting the...
Research suggests the human brain processes language through systems similar to large language models, operating as a separate neurobiological system rather than being central to thought itself.
Researchers at the Indian Institute of Science discovered that century-old mathematical formulas by Indian mathematician Srinivasa Ramanujan for calculating pi naturally emerge in modern physics theories describing black holes,...
A four-wheeled robot that can lean into slopes like a motorcycle and carry over 100 pounds is rolling out of Hyundai's labs and into mass production. The South Korean automaker's MobED robot, short for Mobile Eccentric Droid,...
The world's ten longest tunnels showcase humanity's engineering prowess in overcoming geographical barriers, spanning from New York's 85-mile Delaware Aqueduct delivering billions of gallons daily to Mexico City's challenging...
Scientific American editors have selected ten standout fiction books for 2025, spanning genres from space romance to fungal horror. The diverse collection includes Taylor Jenkins Reid's astronaut love story set during the early...
Hengbot's $700-1,000 Sirius AI robot dog promises advanced voice commands and personality development through Amazon's AI technology, but falls short as a consumer product due to significant design flaws. The skeletal-looking...
Northwestern University researchers analyzed used face masks from airplanes and hospitals to study air quality, discovering that both environments contain mostly harmless skin bacteria rather than dangerous pathogens. The 407...
Scientists analyzed 3.3-billion-year-old olivine crystals and found geochemical evidence that subduction and continental crust formation were already active during Earth's earliest era, challenging the long-held belief that early...
Scientists created erbium-based molecular qubits that work with existing fiber-optic networks at standard telecommunications wavelengths. These qubits could enable scalable quantum networks using current infrastructure, but need...
Scientists from NOAA and NASA report that the 2025 Antarctic ozone hole is the fifth smallest since 1992, covering an average of 7.23 million square miles and breaking apart three weeks earlier than usual. The smaller hole...
Scientists discovered a massive lithium deposit worth up to $1.5 trillion inside the McDermitt Caldera, a collapsed supervolcano on the Nevada-Oregon border, containing an estimated 20-40 million tons of lithium-rich clay. The...
UCLA researchers successfully completed the world's first robotic cataract surgery using their Polaris platform, achieving unprecedented 0.053 millimeter precision in a study of 10 patients with no adverse events. The...
