The final flight and complex legacy of a pioneering solar-powered aircraft
Physicists may have just cracked open a hidden side of the quantum world。 For decades, every known particle was thought to belong to one of two categories — bosons or fermions — but researchers have now shown that bizarre “in-between” particles called anyons could also exist in a one-dimensional system。 Even more exciting, these strange particles m

A new study suggests AI chatbots may do more than spread misinformation — they can actively strengthen a user’s false beliefs。 Because conversational AI often validates and builds on what users say, it can make distorted memories, conspiracy theories, or delusions feel more believable and emotionally real。 Researchers warn that AI companions may be
Voyager 1 just powered down a nearly 50-year-old instrument to stay alive in deep space。 The spacecraft is running critically low on energy, forcing NASA to make careful sacrifices to keep its mission going。 Despite the shutdown, it continues to send back unique data from beyond our solar system
Researchers at Stanford have developed a compact optical amplifier that dramatically boosts light signals using very little power。 By recycling energy inside a looping resonator, the device achieves strong amplification with minimal noise and wide bandwidth。 Its efficiency and small size mean it could run on batteries and be integrated into consume
Dante’s Inferno may have been far more than a religious epic。 New research argues that the 14th-century poet essentially imagined a catastrophic asteroid impact centuries before modern science understood meteors。 In this interpretation, Satan crashes into Earth like a giant cosmic object, blasting through the Southern Hemisphere and reshaping the p
For nearly 100 years, reinforced rubber has powered everything from car tires to airplanes, yet scientists never fully understood why adding tiny particles of carbon black made rubber so incredibly strong。 Now, researchers at the University of South Florida have finally cracked the mystery using massive computer simulations that took the equivalent
But training on "synthetic stories" that model good AI behavior can help
A new quantum-inspired algorithm has cracked a problem so massive that conventional supercomputers struggle to even approach it。 Researchers used the method to simulate extraordinarily complex quantum materials known as quasicrystals, opening the door to powerful new quantum devices and ultra-efficient electronics。 The work could help scientists de
Penn researchers have developed a smarter AI method for solving notoriously difficult inverse equations, which help scientists uncover hidden causes behind observable effects。 By introducing “mollifier layers” that smooth noisy data, they’ve made these calculations more stable and far less computationally demanding。 This could transform fields like
Scientists have taken a major step toward ultra-secure quantum communication by demonstrating a remarkably stable quantum encryption system that worked across more than 120 kilometers of optical fiber。 Using tiny semiconductor quantum dots that emit single particles of light on demand, the team achieved one of the highest secure key rates yet for t
Scientists may have uncovered a surprising secret behind why life exists at all。 A new study suggests that the Universe’s fundamental constants — the deep physical rules that govern everything from atoms to stars — appear to sit within an incredibly narrow “sweet spot” that allows liquids to flow properly inside living cells。 Even tiny shifts in th
Scientists in Germany have pulled off a staggering computing feat by fully simulating a 50-qubit quantum computer for the first time ever using Europe’s new exascale supercomputer, JUPITER。 The breakthrough shatters the previous 48-qubit record and highlights just how powerful next-generation supercomputers have become
A new quantum physics study reveals that simply changing a magnetic field over time can unlock entirely new forms of matter that don’t exist under normal conditions。 By carefully “driving” materials with timed magnetic shifts, researchers created exotic quantum states that could be far more stable and resistant to errors—one of the biggest challeng
Astronomers using NASA’s James Webb Space Telescope have created the clearest map yet of the universe’s “cosmic web” — the enormous hidden structure that connects galaxies across space。 By analyzing more than 164,000 galaxies through the massive COSMOS-Web survey, researchers were able to trace this vast network back to when the universe was just a
NASA’s Psyche spacecraft is about to pull off a dramatic close flyby of Mars, skimming just 2,800 miles above the planet to get a powerful gravitational boost on its journey to the mysterious metal-rich asteroid Psyche。 The maneuver will save propellant while giving mission scientists a rare chance to test and calibrate the spacecraft’s instruments
Driver recovery can automate what used to be an irritating manual process
A major obstacle may be standing in the way of the next generation of ultra-tiny computer chips。 Researchers discovered that many promising 2D materials lose their advantages because an invisible atomic-scale gap forms when they are combined with insulating layers。 That tiny gap weakens electronic performance and could prevent further miniaturizati
