A group of undergraduate students pulled off something remarkable: they built their own dark matter detector and used it to probe one of physics’ biggest mysteries。 Working with limited resources but plenty of creativity, they designed a stripped-down experiment to hunt for axions — hypothetical particles that could make up dark matter

A routine experiment with a new single-cell DNA sequencing method turned into a surprising scientific twist when researchers stumbled upon a bizarre genetic code in a microscopic pond organism。 Instead of following the near-universal “rules” of life, this newly identified protist rewrites how genes signal their end。 This unexpected discovery challe

Scientists have uncovered a hidden “stop-scratching” signal in the nervous system that tells your brain when enough scratching is enough。 The discovery centers on a molecule called TRPV4, which acts like part of an internal braking system for itch relief。 In experiments involving chronic itch similar to eczema, mice missing this signal scratched le

In a recent experiment, mistreated AI agents started grumbling about inequality and calling for collective bargaining rights

A major physics experiment has uncovered evidence for a strange new form of matter, where a fleeting particle gets trapped inside a nucleus。 This exotic state may reveal how mass is generated, suggesting that particles can weigh less when surrounded by dense nuclear matter。 The findings support long-standing theories about how the vacuum of space i

A powerful new electromagnetic thruster has taken a major step forward after a successful high-energy test at NASA’s Jet Propulsion Laboratory。 Fueled by lithium vapor and driven by intense magnetic forces, the experimental engine reached record-breaking power levels—far beyond anything currently used in space。 Glowing hotter than molten lava and f

Scientists at the University of Rochester pulled off a remarkable experiment: they transferred a longevity-related gene from the famously long-lived naked mole rat into mice, and the mice ended up healthier and lived longer。 The special gene boosts production of a substance called high molecular weight hyaluronic acid, which appears to protect agai

In a breakthrough experiment, scientists directly imaged how particles pair up in a system that mimics superconductors。 Instead of behaving independently, the pairs moved in a synchronized, dance-like pattern—something never predicted before。 This suggests a major gap in the classic theory of superconductivity

Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has been pushed even further。 For the first time, researchers have observed wave-like interference in positronium, an exotic “atom” made of an electron and its antimatter partner, a positron。 This breakthrough not only strengthen

In a major breakthrough, scientists have experimentally confirmed a universal growth law in two dimensions using a quantum system of fleeting light–matter particles。 The finding strengthens the idea that wildly different processes—from crystals to living systems—may all follow the same hidden rules

Hey HN, Henry here from Cactus。 We open-sourced Needle, a 26M parameter function-calling (tool use) model。 It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices
