A mysterious glow of gamma rays at the center of the Milky Way has long hinted at dark matter, but the lack of similar signals in smaller dwarf galaxies has cast doubt on that idea。 Now, researchers propose a bold twist: dark matter might not be a single particle at all, but a mix of two different types that must interact with each other to produce
Scientists have uncovered a surprising new picture of human origins that challenges the long-held idea of a single ancestral population in Africa。 By analyzing genetic data from diverse modern African groups—especially the highly distinct Nama people—and comparing it with fossil evidence, researchers found that early humans likely evolved from mult
Ancient Earth once buzzed with enormous dragonfly-like insects, and scientists long thought high oxygen levels made their size possible。 A new study overturns that idea, revealing insect flight muscles weren’t constrained by oxygen after all。 Their breathing system has plenty of room to expand, meaning oxygen alone can’t explain their giant forms
The brain’s memory center may begin life more like a crowded web than an empty canvas。 Researchers discovered that early neural networks in the hippocampus are dense and seemingly random, then become more organized by shedding connections over time。 This pruning process creates a faster, more efficient system for linking experiences and forming mem
A light-sensitive crystal is opening the door to a new era of “light-written” technology。 Arsenic trisulfide can be reshaped and permanently altered using simple light, creating ultra-fine optical patterns without expensive manufacturing tools。 Scientists even etched a nanoscale portrait of Einstein and high-density patterns that could act as secur
Scientists have created tiny “optical tornadoes” — swirling beams of light that twist like miniature whirlwinds — using a surprisingly simple setup based on liquid crystals。 Instead of relying on complex nanotechnology, the team used self-organizing structures called torons to trap and manipulate light, causing it to spiral and rotate in intricate
Senator decries "blatant, brazen corruption," wants to target Trump admin next
Different hunting patterns seem to dictate different distributions of metal
Scientists have created a powerful new way to control quantum systems, achieving the first-ever demonstration of quadsqueezing—an elusive fourth-order quantum effect。 By combining simple forces in a clever way, they made previously hidden quantum behaviors visible and usable, opening new frontiers for quantum technology
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
Physicists have taken a major step toward using AI not just to analyze data, but to uncover entirely new laws of nature。 By combining a specially designed neural network with precise 3D tracking of particles in a dusty plasma—a strange “fourth state of matter” found from space to wildfires—the team revealed hidden patterns in how particles interact
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
The outage has hampered communication concerning a critical vulnerability that gives root
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
