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
Ask HN: What is the AI setup for an experienced dev starting on a new project?
I have been working as a software developer for more than 20 years now. Been around the block a few times. Thanks to generous allowances in my current place, I've dipped my toes into LLM world and am quite impressed with it. However, we are on a legacy code base, LLM impact is limited in a sense. If I was to start a new project (let's say a web app with backend) - what is the state of the art for the setup? From Issue tracking, CI, automated deployments, agents, documentation etc - is
Show HN: Gitdot – A better GitHub. Open-source, written in Rust
What works now: user signups, org creations, private/public repos, and importing GitHub repositories (both as read-only mirrors and full migrations). So basically, you can create, push and pull to a repo, but we don't have many features quite yet (issues, PRs, CI).What is a bit unique is: 1) we built it in Rust and 2) the website is a little odd. Its design is inspired by CLIs (e.g., fzf, broot, vim) instead of web apps, and as such, lacks some affordances that you might typically expe
Show HN: Mach – A compiled systems language looking for contributions
Hi HN,I'm the creator of Mach (https://github.com/octalide/mach or https://machlang.org). Two days ago, we finally achieved full self hosting. I wanted to make a post here to show off the language since this is a big milestone for us.## TL;DR about the language for those curious:- There are no external dependencies anywhere in the pipeline. This includes LLVM, libc bindings, or anything of the sort (save for the historical bootstrap compiler, which requires any
Show HN: Guestlist – know which sites will let your agent in
I've been building computer-use agents prototypes for the last few months and I had a reoccurring problem: many sites the agent should be able to use (common SaaS dashboards, retail sites, newspapers etc) just block it by recognizing them as non-humans. The problem is that this always leads to longer execution times since the agent doesn't know when to call it quits and just runs in a loop until forced timeout or worse it returns hallucinations. This was especially bad for swarm proje

Show HN: Welter's game, a little Nim-like combinatorial game
Hi HN! Here's a little game I (and my buddy Claude, cf. the obvious CSS gradient tell) set up to explain to my kids some of things we were working on at work.So in the game you're taking turns moving coins down a line until no moves are possible. If you've taken a course on combinatorial game theory, you'll have come across the game of nim and you can think of this one as a variant of nim where there can only be a single coin in every square. The theory of how to play it isn&
Show HN: Persist.chat – Outreach and Sales Agents
Hello HNs,Meet persist.chat - outreach agents that runs itself. It will find you prospects on the internet and reach out to them and do personalized followups till you secure a sell.Also bring your contacts, and launch campaigns with personalized followups. it runs 24/7 with out you looking.Most founders quit because of the assumption of vitality on 3-7 days of after building apps. unfortunately that's not how the internet works. Your website might take unto 7-14 days to get indexed. a
Show HN: Leash, a low-dopamine mobile browser replacement
Hello!In an attempt to reduce my time spent on screens (and more time in real life), I uninstalled social media from my phone ages ago. The same for email: only on desktop for me.At some point, I discovered that I would, however, not spend that much less time on my phone, but rather 'migrate' to other habits, such as impulse checking of news sites.A mobile browser is like a fridge full of sweets if you're trying to stay on a healthy diet.So I've been living without a mobile b
MIT’s new spacecraft engine could send tiny satellites to Mars
MIT researchers have shown that one fuel can power both chemical and electric spacecraft thrusters, potentially transforming what small satellites can do. The approach combines quick bursts of speed with highly efficient long-range propulsion in a single compact system. A NASA-supported CubeSat mission will soon test the technology in orbit.
Majorana modes withstand disorder in atomic chains, boosting fault-tolerant quantum computing
Quantum computers—systems that process information and perform computations by leveraging the principles of quantum mechanics—could solve some tasks faster and more effectively than classical computers. While some studies have demonstrated the advantages of these computers for specific tasks, ensuring their reliable operation in real-world settings has proved challenging.
A classic brain test exposed AI's biggest weakness
Researchers gave top AI models a classic attention test used in psychology and found a major flaw. While the models could correctly name colors in short lists, their performance deteriorated sharply as the task became longer and more complex. Some leading systems fell from over 90% accuracy to nearly complete failure.
Quantum witness technique reveals spinons in quantum spin liquid candidate
Physicists at University College Cork have developed a new approach in the search for a quantum spin liquid, a long-sought state of quantum matter resembling a magnetic liquid whose quantum properties mean it never freezes. The work is a key step in the search for quantum silicon, a mineral that could be used to create quantum computers, just as silicon is used in traditional computers. The resulting paper appears in Nature Physics.
Physicists harness potential of quantum phase transitions
Researchers at University College Dublin and international collaborators have just published a detailed and accessible guide that aims to translate theoretical ideas into practical devices for quantum enhanced sensing technologies.
Physicists observe synchronized quantum dance of excitons and phonons
An international team of researchers has reported a major advance in understanding quantum dynamics in semiconductor materials. They directly observed how excitons and phonons evolve together in perovskite nanocrystals, revealing a fully coherent quantum dance between light-induced electronic excitations and crystal lattice vibrations. They published their findings in Nature Communications.

New buried-growth process enables 2D arrays of position- and orientation-controlled diamond qubits
Researchers at Kanazawa University, in collaboration with Diamond and Carbon Applications (Germany), have developed a buried-growth process for nitrogen–vacancy (NV) centers in diamond using microwave plasma chemical vapor deposition (MPCVD). By employing nitrogen-radical selective etching, which simultaneously enhances metal-mask durability through nitridation, the team enabled a continuous etching–growth sequence within a single MPCVD process.
Quantum memory surpasses classical limits for storing unknown quantum operations
Quantum memories, systems that store and retrieve information leveraging quantum mechanical effects, can outperform classical storage systems on some existing tasks. Yet these promising memories could also complete operations that are very difficult or impossible for classical systems, including the storage and retrieval of so-called isometry channels.
Scientists think they solved the mystery of the Amaterasu particle
The mysterious Amaterasu particle may not be a proton at all. New research suggests that some of the most extreme cosmic rays could be ultraheavy atomic nuclei, heavier than iron, which are better able to retain their energy while traveling through space. This idea could help explain how these rare particles reach Earth and provide new clues about the powerful cosmic explosions that create them.
