MIT engineers develop a magnetic transistor for more energy-efficient electronics

Transistors, the building blocks of modern electronics, are typically made of silicon. Because it’s a semiconductor, this material can control the flow of electricity in a circuit. But silicon has fundamental physical limits that restrict how compact and energy-efficient a transistor can be.MIT researchers have now replaced silicon with a magnetic semiconductor, creating a magnetic transistor that could enable smaller, faster, and more energy-efficient circuits. The material’s magnetism strongly

Black holes may avoid singularities when charge and Hawking radiation combine, theoretical physicist argues

Black holes are regions in space where gravity is so strong that nothing, even light, can escape. Einstein's theory of general relativity breaks down inside black holes, either by the presence of a so-called "curvature singularity" or "Cauchy horizon."

When noisy decision-making becomes a strategic advantage

A new study shows that apparently erratic or "sloppy" behavior in strategic situations is not necessarily a mistake. Under certain conditions, being less sensitive to one's own gains can become a long-term advantage.

Made a Chrome extension that stops me from sending dumb messages

3 weeks ago i almost sent a passive-aggressive "ok cool" to my CTO at 11pm. caught myself in time. realized this happens to me like weekly so i built a thing for it.it's called cooldown. when you hit post/send/tweet, a small modal pops up with a countdown (10s by default). you can cancel or send anyway. that's it.the part i actually like about it: it doesn't trigger on every message. that would be insanely annoying. it only kicks in when the message is: - long

Show HN: Haystack – Review the PRs that need human attention

Hey HN! We're building Haystack (https://haystackeditor.com/) to help teams deal with the explosion in the number of pull requests that need to be reviewed due to the rise of coding agents.Haystack replaces the GitHub PR review system with a queue that triages each PR before a human has to read any diffs. It looks at the diffs, the codebase, and the coding-agent conversation that produced the PR. Haystack then routes it into one of three buckets:1. Safe to merge. This means t

Show HN: 5 Minute Frenzy – free multiplication practice game for kids

My kids love maths. A key part of that is being at ease with the fundamentals - if a kid struggles with the fundamentals, it’s hard to build confidence on top of that. One of those fundamentals is being really good at times tables. At home we’ve always tried to make learning fun, and enjoyed adding a little competition to it too.At school (an international school in Portugal for english-speaking students), they also use lots of fun strategies to teach kids their times tables. One of those is cal

Ask HN: Transition from Engineering Manager to IC

I work at a FAANG. Engineering manager since 2015. I have been asked to choose between taking IC role in the same team or take severance. My goal is to quit and do my own tech startup in a year or so. What option should I choose now?

Ask HN: How are agentic workflows meant to offset AI debt?

I don't know quite how to put it. But projects I inherit and am supposed to get over the line have this same strange quality: they are 'undesigned'.I believe this may be because processes and context-related code that was previously considered with basic design principles and functionality seem not so much to be missing, but they have they seem to be simulated. Giving the impression of being considered, which is quite difficult for a project manager to catch.So I'm now spe

Molecule-in-a-crystal system could boost quantum computing via chemically engineered qubits

Within a crystal's atomic structure, tiny atomic-scale flaws will naturally occur where electrons can become trapped. These defects have emerged as one of the leading platforms for quantum information processing. Through a new study, posted to the preprint server arXiv, Ilai Schwartz and colleagues at NVision Imaging Technologies in Germany have shown that a specialized molecule embedded inside a crystal could take this approach a step further, offering a more controllable and versatile route to

Scientists discover strange “narwhal” waves that trap light beyond known limits

Physicists at Peking University have uncovered a new way to confine light far beyond conventional limits — without relying on metals and their inherent energy dissipation. By formulating the singular dispersion equation, the team discovered narwhal-shaped wavefunctions that trap light at deep-subwavelength volumes in purely dielectric materials. The advance, dubbed singulonics, could pave the way for ultra-efficient photonic chips, new quantum technologies, and imaging tools with unprecedented r

Physicists finally solve the strange mystery of “breathing” lasers

Scientists have finally figured out how mysterious “breather” laser pulses work, solving a puzzle that has frustrated laser physicists for years. These unusual ultrafast lasers produce light pulses that rhythmically grow and shrink instead of staying steady, almost like they’re breathing.

Jupiter’s lightning may be 100x more powerful than Earth’s

Jupiter’s storms aren’t just gigantic — they may unleash lightning far more powerful than anything on Earth. Using NASA’s Juno spacecraft, scientists discovered that some lightning bolts on the gas giant could pack up to 100 times the punch of Earth’s lightning, and possibly much more. The findings reveal that Jupiter’s atmosphere works very differently from our own, with massive storms building enormous amounts of energy before erupting in violent flashes across cloud tops towering more than 10

Scientists discover a strange “inside-out” planetary system that shouldn’t exist

Scientists have discovered a bizarre planetary system where a rocky world orbits farther out than giant gas planets, defying long-standing theories of planet formation. The finding hints that some planets may form much later than expected — and that our Solar System might not be as typical as we thought.

Dopamine drives persistent remodelling of the maternal brain

New quantum sensor could count individual photons and hunt dark matter

Researchers have built an ultra-sensitive sensor capable of detecting unimaginably small amounts of energy — below one zeptojoule. The breakthrough relies on fragile superconducting materials that react to even the slightest temperature change. This level of precision could improve quantum computers, enable photon counting, and even help scientists detect elusive dark matter particles from space.

Quantum sensors use atoms, electrons and light as ultra‑steady rulers

Quantum computers get a lot of attention, even though they are not ready for prime time, but quantum sensors are already doing useful work. These sensors measure fields, forces and motion so small that ordinary background noise can drown them out. Some sensors are already in daily use, while others are moving from research labs into flight tests, hospitals and field instruments.
