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

Show HN: Questle – Daily Mindful Side Quests That'll Make You Say What?
A friend and I made this project (with a little help from Claude, naturally).We wanted to create a wordle-esque shared experience, so everyone gets the same quests and those quests should have some meaningful impact on your day.The approach we took was to create around 100 sentence structure templates that used a selection of verb and noun arrays. These were nested so depending on the sentence you might want all "things" (a very large list) or perhaps more granular like "things.fu
Show HN: Try [name-redacted] AI video model
Hi HN,I’m building an AI video playground where people can try different text-to-video models in one place. We recently added support for [name-redacted], [name-redacted] latest video model, and I thought some of you might like to experiment with it.[url-redacted]A few things that stood out when testing [name-redacted]:It often generates multi-shot sequences instead of a single static shotMotion can be quite smooth compared to earlier T2V modelsIt supports native audio generationPrompts with cam
Show HN: Kanban-md – File-based CLI Kanban built for local agents collaboration
I built kanban-md because I wanted a simple local task tracker that works well for the agent loop: drop tasks in, run multiple agents in parallel, avoid collisions, and observe progress easily.Tasks are just Markdown files (with YAML frontmatter) in a `kanban/` next to your code — no server, no DB, no API tokens. Simple, transparent, future-proof.What makes it useful for multi-agent workflows:- *Atomic `pick --claim`* so two agents don’t grab the same task.- *Token-efficient `--compact` out
Show HN: 3D Modelling in CSS
When I first built this a few years ago, someone else submitted it to HN before I could. I'm sharing it now myself after making some performance improvements, though it's still quite unusable on certain devices (apologies).
Show HN: Browse Internet Infrastructure
I'm launching Wirewiki.com today!Wirewiki makes the internet’s hidden infrastructure browsable.I quit my job 5 years ago to scale Nslookup.io. But after reaching 600k monthly users, I hit a ceiling. I couldn't naturally expand beyond DNS because of the domain name.So I went back to the drawing board: how would I make it today? Not as a collection of tools, but as a browsable graph.I've spent hundreds of hours and commits building that. It's not even at 10% of what I want it t
Machine learning reveals hidden landscape of robust information storage
In a new study published in Physical Review Letters, researchers used machine learning to discover multiple new classes of two-dimensional memories, systems that can reliably store information despite constant environmental noise. The findings indicate that robust information storage is considerably richer than previously understood.
A simple discovery is shaking the foundations of spintronics
A long-standing mystery in spintronics has just been shaken up. A strange electrical effect called unusual magnetoresistance shows up almost everywhere scientists look—even in systems where the leading explanation, spin Hall magnetoresistance, shouldn’t work at all. Now, new experiments reveal a far simpler origin: the way electrons scatter at material interfaces under the combined influence of magnetization and an electric field.
AI reads brain MRIs in seconds and flags emergencies
Researchers at the University of Michigan have created an AI system that can interpret brain MRI scans in just seconds, accurately identifying a wide range of neurological conditions and determining which cases need urgent care. Trained on hundreds of thousands of real-world scans along with patient histories, the model achieved accuracy as high as 97.5% and outperformed other advanced AI tools.
Physicists discover what controls the speed of quantum time
Time may feel smooth and continuous, but at the quantum level it behaves very differently. Physicists have now found a way to measure how long ultrafast quantum events actually last, without relying on any external clock. By tracking subtle changes in electrons as they absorb light and escape a material, researchers discovered that these transitions are not instantaneous and that their duration depends strongly on the atomic structure of the material involved.
Scientists Send Secure Quantum Keys Over 62 Miles of Fiber—Without Trusted Devices
The strongest known form of quantum-secure communication is no longer limited to tabletop experiments. Quantum communication could enable uncrackable transfer of information, but most approaches rely on trusted devices. Researchers have now demonstrated that a new method that does away with this challenging requirement can operate over distances as large as 62 miles.One of the central promises of a future quantum internet is provably secure communication. That’s thanks to one of the quirks of qu
Laser‑written glass chip pushes quantum communication toward practical deployment
As quantum computers continue to advance, many of today's encryption systems face the risk of becoming obsolete. A powerful alternative—quantum cryptography—offers security based on the laws of physics instead of computational difficulty. But to turn quantum communication into a practical technology, researchers need compact and reliable devices that can decode fragile quantum states carried by light.
Why elite chess ratings get stuck: A new model treats draws as data
Here's a statistical challenge worthy of a grandmaster: How do you create an accurate ranking system when the best players usually don't win? This is the conundrum of elite chess. The stronger the players, the greater the odds of the match ending in a draw.
Quantum dots reveal entropy production, a key measure of nanoscale energy dissipation
In order to build the computers and devices of tomorrow, we have to understand how they use energy today. That's harder than it sounds. Memory storage, information processing, and energy use in these technologies involve constant energy flow—systems never settle into thermodynamic balance. To complicate things further, one of the most precise ways to study these processes starts at the smallest scale: the quantum domain.
Leading AI models struggle to solve original math problems
Mathematics, like many other scientific endeavors, is increasingly using artificial intelligence. Of course, math is the backbone of AI, but mathematicians are also turning to these tools for tasks like literature searches and checking manuscripts for errors. But how well can AI perform when it comes to solving genuine, high-level research problems?
