Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, their internal forces compete, causing constant rearrangements that dramatically increase resistance at certain distances. This creates a surprising peak in friction instead of a steady rise, breaking a long-standing physics law.

In an incredibly lucky cosmic accident, NASA’s Hubble Space Telescope captured a comet breaking apart in real time—something astronomers have long tried and failed to observe. The comet, C/2025 K1 (ATLAS), wasn’t even the original target, but when researchers pivoted to it, they unknowingly caught it mid-disintegration into multiple pieces.

Scientists at Harvard have built a miniature device that can twist and tune light in real time. By rotating two stacked photonic crystals and adjusting their spacing with a tiny mechanical system, they can control how light’s “handedness” behaves. This allows the chip to distinguish between left- and right-circular polarized light with remarkable precision. The

A mysterious spike of platinum buried deep in Greenland’s ice has long fueled theories of a catastrophic comet or asteroid strike 12,800 years ago—possibly triggering a sudden return to icy conditions known as the Younger Dryas. But new research points to a far less dramatic, yet still powerful culprit: volcanic eruptions. Scientists found the platinum

Researchers have created a cutting-edge catalyst that turns CO2 into methanol more efficiently than ever before. Instead of using clumps of metal atoms, they engineered a system where each single indium atom actively drives the reaction. This dramatically reduces energy needs while making the process easier to study and optimize. The result could accelerate the

A nearby galaxy is behaving strangely—and now scientists know why. The Small Magellanic Cloud’s stars move in chaotic patterns because it slammed into its larger neighbor millions of years ago. That collision disrupted its structure and even created the illusion that its gas was rotating. The discovery means this once “textbook” galaxy may not be

A new subatomic particle known as the Ξcc⁺ has been discovered at CERN’s Large Hadron Collider. This heavy proton-like particle contains two charm quarks and was detected using the upgraded LHCb experiment. Scientists observed it through its decay into lighter particles in high-energy collisions. The finding confirms predictions and settles a decades-long question about its

AI’s growing energy use sounds alarming, but its global climate impact may be far smaller than expected. Researchers found that while AI consumes huge amounts of electricity, it barely moves the needle on overall emissions. The real impact is more localized, especially around data centers. Meanwhile, AI could become a powerful tool for building greener

Astronomers have identified a strange new kind of exoplanet that challenges how scientists classify worlds beyond our Solar System. The planet, L 98-59 d, appears to contain a vast ocean of molten rock beneath its surface that traps large amounts of sulfur deep inside. Observations from the James Webb Space Telescope revealed unusual sulfur-rich gases

A new tomato-picking robot is learning to think before it acts. Instead of simply identifying ripe fruit, it predicts how easy each tomato will be to harvest and adjusts its approach accordingly. This smarter strategy boosted success rates to 81%, with the robot even switching angles when needed. The breakthrough could pave the way for
