Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo that mirrors today’s mechanism. The results illuminate Earth’s early history, life’s origins, and the magnetism of other planets. Plus, it could help forecast future changes […]

Complex, intelligent life in the galaxy appears vanishingly rare, with the nearest possible civilization perhaps 33,000 light-years distant. Yet despite the odds, scientists insist that continuing the search for extraterrestrial intelligence is essential — for either outcome reshapes our understanding of life itself.

A team at the University at Buffalo has made it possible to simulate complex quantum systems without needing a supercomputer. By expanding the truncated Wigner approximation, they’ve created an accessible, efficient way to model real-world quantum behavior. Their method translates dense equations into a ready-to-use format that runs on ordinary computers. It could transform how

Scientists using a global array of radio telescopes have detected the universe’s lowest-mass dark object by observing how it warped light through gravitational lensing. The invisible mass, about a million times the Sun’s weight, could be a small clump of dark matter or a dormant dwarf galaxy. The finding supports cold dark matter models and

A team of engineers at North Carolina State University has designed a polymer “Chinese lantern” that can rapidly snap into multiple stable 3D shapes—including a lantern, a spinning top, and more—by compression or twisting. By adding a magnetic layer, they achieved remote control of the shape-shifting process, allowing the lanterns to act as grippers, filters,

Scientists have developed an ultra-thin, paper-like LED that emits a warm, sunlike glow, promising to revolutionize how we light up our homes, devices, and workplaces. By engineering a balance of red, yellow-green, and blue quantum dots, the researchers achieved light quality remarkably close to natural sunlight, improving color accuracy and reducing eye strain.

USC engineers have developed an optical system that routes light autonomously using thermodynamic principles. Rather than relying on switches, light organizes itself much like particles in a gas reaching equilibrium. The discovery could simplify and speed up optical communications and computing. It reimagines chaotic optical behavior as a tool for design rather than a limitation.

Scientists at EPFL have reimagined 3D printing by turning simple hydrogels into tough metals and ceramics. Their process allows multiple infusions of metal salts that form dense, high-strength structures without the porosity of earlier methods. Early results show materials 20 times stronger with much less shrinkage. The breakthrough could lead to efficient production of complex

Our everyday GPS struggles in “urban canyons,” where skyscrapers bounce satellite signals, confusing even advanced navigation systems. NTNU scientists created SmartNav, combining satellite corrections, wave analysis, and Google’s 3D building data for remarkable precision. Their method achieved accuracy within 10 centimeters during testing. The breakthrough could make reliable urban navigation accessible and affordable worldwide.

Asteroid 2025 TF zipped past Earth above Antarctica, coming within 428 km of the surface. Roughly the size of a small car, it was detected hours after the flyby and posed no danger. ESA astronomers later confirmed its trajectory with extraordinary accuracy.
