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
IBM CEO says quantum computing will have a 'measurable impact' on earnings by 2028 or 2029
IBM CEO Arvind Krishna said the company's investments in quantum computing should begin to have "a measurable impact" on revenue and earnings by 2028 or 2029.
Quantum computers are starting to become useful as scientific tools
Three problems that are out of reach for conventional computers have been cracked by quantum computers and show how important the machines could become for scientific research
Is the quantum threat to Bitcoin real or not? Galaxy Digital just pledged $5 million to boost Bitcoin's quantum resistance.
Money is now moving to help protect the coin from its biggest emerging threat.

Ask HN: Why did Fastify never get more hype?
I've been checking current frameworks for Node.js, and it seems, for example, that Hono is quite popular and gets supported by different solutions (e.g. AI agent libraries) much easier than Fastify, despite being relatively young.<p>I've been thinking why Fastify never got more popular despite being seemingly good, battle-tested, and Matteo Collina's authority.
Show HN: An LSP for agent skills–rename, references, completion, and diagnostics
I was quite surprised to find no one had built an LSP for agent skills — one where you can go-to-definition, get skill-completions, refactor (and it renames the folder and the name:), so I went ahead and built one!(Reminds me of the old Ruby on Rails days where we had to find-and-replace-all in our codebase to refactor things lol.)Since submitting this on Monday, I've expanded it to provide:- 1-click install for VS Code, Cursor, Windsurf, VSCodium, Zed- References & description-on-hover
Ask HN: Has Claude Code been (mostly) usable for you?
I have just had my 3rd session in less than a week when I had to eventually quit Claude Code and do a task using another model/subscription.<p>Am I just unlucky?<p>EDIT: it is working again. Today I was asking for research and I kept getting warnings that the model was unavailable (Opus 4.8)
Show HN: BlazeRules – YAML rule engine for streaming data, 5M records/SEC
https://blazerules.devI initially wanted to make a sub-millisecond log parser in C++ but that blew into a embeddable decision engine, that can run YAML defined rules on incoming data. The rules are executed in a vectorized format on incoming data by reprojecting into a columnar format first, if it's not already. Depending on the payload size and rules complexity, the performance goes from 200K records/s to more than million records/sec, in terms of througput this would b
Show HN: Wienerdog – memory and self-improving skills for Claude Code/Codex
The idea of Wienerdog was born out of my experience setting up my own simple but effective system of memory, self-improving skills and hooks for Claude Code and Codex. As I was teaching my friends and colleagues how to set up their own I found myself automating more and more of my system setup and finally I decided to publish it on GitHub to help others get more out of their AI usage.So what is Wienerdog? Simply put, it is just files — no daemon, no server, no telemetry: a collection of instruct
Dark matter’s secret force does the opposite of what scientists expected
Dark matter particles may exert a hidden force on one another, but its effects are stranger than expected. An extra attraction helps the particles cluster, yet it also makes dark matter effectively lighter as the Universe expands. That weakens its gravitational impact and usually slows the growth of cosmic structure rather than accelerating it.
Mathematicians prove perfectly fair elections are impossible
Mathematicians have shown that no electoral system can perfectly balance local representation, proportional national results, and a fixed-size parliament once enough parties compete. A newly proposed voting method could soften these unavoidable trade-offs and produce outcomes that are much closer to fair.
Mysterious Milky Way object accelerates protons beyond one quadrillion electron volts
Scientists have identified LHAASO J1912+1014u as a cosmic accelerator that can push protons beyond one quadrillion electron volts. The finding may help reveal where the Milky Way’s most energetic cosmic rays come from and how they influence the galaxy.
IBM and Qedma Demonstrate Quantum Advantage, Modeling Physics Beyond Classical Capabilities Through Trusted Quantum Computation

Why full-fledged quantum computers might always be five years away
To predict when we’ll have a truly useful quantum computer, we need to know precisely what one is. Columnist Karmela Padavic-Callaghan finds that’s harder to pin down than you might think ...
Unusual metal oxide shows signs of magnetism under lattice strain in ultrathin layers
Ruthenium dioxide (RuO2) is a metal oxide that commonly serves as an important metallic conductor, quantum material and industrial electrocatalyst. While there have been debates surrounding the magnetic properties of RuO2, it is generally thought to be nonmagnetic in its bulk form. But now, a new study, published in Science Advances, has found that very thin layers of RuO2 can become magnetic when its lattice is placed under strain.
