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: CityEdit – Open-source map for voting on NYC street changes
CityEdit (cityedit.org, https://github.com/edbltn/city-edit) is a map where anyone can propose street changes, e.g. safer crossings, new bike lanes, improved tree beds. Neighbors can then vote on those proposals.We just soft launched the app by hanging posters with QR codes at NYC's statistically most dangerous intersections (from open crash data at https://data.cityofnewyork.us/Public-Safety/Motor-Vehicle-Co...).

Show HN: Neal – Codex writes the code, Claude reviews it
neal is a CLI I wrote while trying to use an LLM coding agent (in this case, Codex GPT-5.4) to work autonomously on a migration of our large frontend codebase. A few things came up during that project that guided the development of neal:1. Telling an agent to "keep working unless blocked" doesn't actually work over long stretches of time.2. Large projects should be broken up into smaller chunks of work.3. The coding agent should start each chunk of work with a fresh context to pre
Show HN: Ocean – All your team's agent sessions in one place
I spend a lot of time in Claude Code and Codex with my friend. We kept losing the context behind changes because every agent session lived on one person's laptop, and by the time code made it into a PR, all the reasoning was gone.We tried commits, PRs, and docs, but they only really capture the end result, so we built a tool to keep all of our agent sessions in one searchable place.Now we (and our agents) can check out anyone's session and ask things like "what was Alex working on
Show HN: I made a self-built catalogue of education Simulation games
I'm quite intrigued by the new domain unlocked by AI - Simulation games!I want this catalogue to be education related, for players to take something home after playing the game.I'm a researcher of this domain, I will add more games, right now these are available:1. Race to AGI - Can you fight against the odds and run a Frontier AI Labs?

Sunlight-powered setup generates quantum entanglement
Today's quantum technologies rely on energy-intensive lasers, raising concerns that scaling them up could further increase energy demands. In new work, researchers have demonstrated that quantum entanglement between photons can be generated directly from sunlight, offering a potential alternative.
Engineers build world's first portable diamond-powered quantum computer — it works at room temperature and can be plugged into an outlet
A German startup has debuted the world's first diamond-based quantum computing system to exceed 10 qubits.The machine, built by engineers at Saxon Q, is a nitrogen-vacancy (NV) quantum computer, meaning it uses defects in synthetic diamonds as quantum bits (qubits) to perform quantum operations. Qubits can be manipulated to represent the 0s and 1s of data, as well as quantum states that are superpositions of both the 0s and the 1s.The hardware is currently available i
A star’s violent death exposed a hidden supermassive black hole
A supermassive black hole has been found lurking about 30,000 light-years from the center of its galaxy—the first dormant black hole detected so far from a galactic core. It revealed itself only after shredding a passing star and producing a brief, brilliant flare. Astronomers think it may be the remnant of a devoured galaxy or a black hole flung outward during a chaotic cosmic encounter.
Cell-inspired nanoreactor turns sunlight into hydrogen peroxide
A new hollow nanoreactor mimics living cells to make hydrogen peroxide more efficiently using visible light. Its light-trapping cavity and proton-shuttling shell could open new possibilities for cleaner chemical manufacturing and artificial photosynthesis.
A new way to watch heat move through electronics
The same overheating problem that happens to our laptops also plagues computer servers and data centers around the world — and heat management is only getting harder as computer chips get more compact and powerful.Understanding how heat moves through chips at the micro scale is essential for continuing to improve their performance. Unfortunately, most methods for measuring heat flow struggle with multilayered devices like the electronics that power our modern world.Now MIT researchers have demon
Claude Fable 5 AI finds a tiny formula that topples an 87-year-old math conjecture
A mathematician working at Anthropic says he used the AI model Claude Fable 5 to uncover a remarkably simple counterexample to the Jacobian conjecture, a famous problem that has resisted mathematicians for more than a century. The result shows that the conjecture is false in three dimensions and above, although the original two-dimensional version remains unsolved.
Miniaturized laser technology paves the way for fundamental physics experiments in space
An international team of researchers has succeeded in producing atomic quantum gas mixtures with an unprecedented particle flux. In the journal Nature Communications, the scientists report on experiments conducted with the MAIUS-B apparatus, in which Bose–Einstein condensates (BECs) consisting of two different atomic species—rubidium and potassium—were generated and studied under microgravity conditions in the Einstein Elevator at Leibniz University Hannover in Germany.
