Two launches this week delivered 61 more satellites to orbit for the Amazon Leo broadband network
Senator decries "blatant, brazen corruption," wants to target Trump admin next
A major discovery is reshaping how scientists think about catalysts。 Researchers have, for the first time, captured oxygen atoms moving through the interior of a catalyst—not just along its surface。 This reveals that the bulk material can actively participate in reactions, opening a new frontier in catalyst design
Crushing soda cans for science, why dolphins swim so fast, how urine helps mushrooms communicate, and more
Curiosity has detected a surprising variety of organic molecules on Mars, including compounds tied to the chemistry of life。 Some of these molecules may be billions of years old, preserved in ancient clay-rich rocks that once held water。 One standout find resembles building blocks of DNA, raising exciting questions about Mars’ past
Trump lashes out at Cassidy while announcing his new nomination
Scientists have discovered unexpected water-ice clouds on a distant, Jupiter-like exoplanet, challenging current atmospheric models。 By directly imaging Epsilon Indi Ab with the James Webb Space Telescope, they found less ammonia than expected—likely hidden by thick, patchy clouds。 The finding reveals new layers of complexity in giant planets and s
A mysterious magnetic material once thought to host an exotic “quantum spin liquid” has turned out to be something entirely different—and possibly just as intriguing。 Scientists studying cerium magnesium hexalluminate found it showed the hallmark signs of this elusive quantum state, like a lack of magnetic order and a spread of energy states。 But a
AI ModelForge is a platform that teaches men how to generate their own AI influencers
In a striking glimpse into extreme physics, scientists have captured the split-second chaos that unfolds when powerful laser flashes blast matter into a superheated plasma。 By combining two cutting-edge lasers, researchers were able to track how copper atoms lose and regain electrons in trillionths of a second, creating and dissolving highly charge
Scientists are grappling with a cosmic mystery: why does the Universe behave differently on massive scales compared to our own solar system。 While distant galaxies reveal clear signs of something bending the rules of gravity—often attributed to dark energy or a hidden “fifth force”—everything nearby seems to follow Einstein’s playbook perfectly
As the Moon swallowed the Sun during the April 8, 2024, total solar eclipse, something remarkable happened on the ground—cities went eerily quiet。 Scientists analyzing seismic data found that human-generated vibrations, usually caused by traffic, construction, and daily activity, dropped sharply during totality。 The effect was so pronounced that it
AI-powered personas are becoming so realistic that they can infiltrate online communities and subtly steer public opinion。 Unlike traditional bots, they adapt, coordinate, and refine their messaging at a massive scale, creating a false sense of consensus。 Early warning signs—like deepfakes and fake news networks—have already appeared in global elec
Astronomers have long been puzzled by a cosmic mystery: planets orbiting two stars—like Star Wars’ Tatooine—are surprisingly rare, even though they should be common。 New research suggests the culprit is none other than Einstein’s theory of general relativity
A new AI-driven method called GOFLOW is turning weather satellite images into highly detailed maps of ocean currents。 By tracking how temperature patterns shift over time, it can reveal fast-moving, small-scale currents that were previously impossible to observe directly。 These currents are key to understanding climate, marine ecosystems, and carbo
A decades-old cosmic mystery has finally been cracked: the strange X-rays coming from the bright star gamma-Cas are caused by a hidden stellar companion feeding off it。 Using cutting-edge observations from the XRISM space mission, astronomers discovered that an unseen white dwarf star is siphoning material from gamma-Cas, heating it to extreme temp

AWS stops billing Middle East cloud customers as repairs to war damage drag on
A mysterious cosmic explosion has astronomers buzzing, as a strange event may hint at an entirely new kind of stellar cataclysm。 After detecting ripples in space-time, scientists spotted a fast-fading red glow that initially looked like a rare kilonova—the kind of collision that forges gold and uranium。 But just days later, the signal shifted, beha
