Hello HN,I was away from my computer for two weeks, and after coming back and reading the latest discussions on HN about coding assistants (models, harnesses), I felt very out of the loop。 My normal process would have been to keep reading and figure out the latest and greatest from people's comments, but I wanted to try and automate this process。Ba
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
Acoustic fire suppression goes commercial
After two centuries of failed attempts, scientists have finally grown dolomite in the lab, cracking a long-standing geological puzzle。 They discovered that the mineral’s growth stalls because of tiny defects—but in nature, those flaws get washed away over time。 By mimicking this process with precise simulations and electron beam pulses, the team ac
Deep inside planets like Uranus and Neptune, scientists may have uncovered a bizarre new state of matter where atoms behave in unexpected ways。 Advanced simulations suggest that carbon and hydrogen, under crushing pressures and scorching temperatures, can form a strange hybrid phase—part solid, part fluid—where hydrogen atoms spiral through a rigid
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
For decades, psychologists have debated whether the human mind can be explained by one unified theory or must be broken into separate parts like memory and attention。 A recent AI model called Centaur seemed to offer a breakthrough, claiming it could mimic human thinking across 160 different cognitive tasks。 But new research is challenging that bold
Researchers have, for the first time, directly visualized how electronic patterns known as charge density waves evolve across a phase transition。 Using cutting-edge microscopy, they found these patterns form unevenly, breaking into patches influenced by tiny structural distortions。 Unexpectedly, small pockets of order persist even above the transit
A team at King’s College London has created a powerful new aluminum compound capable of doing the work of expensive rare metals。 Its unique triangular structure gives it remarkable stability and reactivity, allowing it to drive chemical reactions in ways never seen before。 The discovery could lead to greener and far more affordable industrial proce
Engineers at Northwestern University have taken a striking leap toward merging machines with the human brain by printing artificial neurons that can actually communicate with real ones。 These flexible, low-cost devices generate lifelike electrical signals capable of activating living brain cells, a breakthrough demonstrated in mouse brain tissue
Scientists have developed a fuel cell that uses microbes in soil to produce electricity。 The device can power underground sensors for tasks like monitoring moisture or detecting touch, without needing batteries or solar panels。 It works in both dry and wet conditions and even lasts longer than similar technologies
In the chaotic first moments after the Big Bang, ripples in spacetime may have done more than just echo through the cosmos—they could have helped create dark matter itself。 New research suggests that faint, ancient gravitational waves might have transformed into particles that eventually became the invisible substance shaping galaxies today
A surprising breakthrough in physics could reshape the future of computing by tapping into a strange, previously untapped property of matter。 Scientists have shown that tiny atomic vibrations—called chiral phonons—can directly transfer motion to electrons, allowing them to carry information without magnets, batteries, or even electricity。 This open
Astronomers have unleashed a powerful new AI tool called RAVEN to comb through data from NASA’s TESS mission—and it’s paying off in a big way。 By analyzing millions of stars, the system has confirmed over 100 exoplanets, including 31 brand-new worlds, and identified thousands more promising candidates。 What makes this especially exciting is the dis
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
Calling AI things like “smart” or saying it “knows” something might sound harmless, but it can quietly mislead people about what AI actually does。 A new study shows that news writers are more careful than expected, rarely using strongly human-like language。 When they do, it often falls on a spectrum—sometimes describing simple requirements, other t
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
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
