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: DomeAPI (YC F25) was acquired. pmxt is the open-source equivalent
Hi HN, I'm the maintainer of pmxt.<p>With Polymarket's recent acquisition of DomeAPI to bring their infrastructure in-house, there is a sudden gap for developers building cross-market arbitrage bots, tracking whale wallets, or running quantitative models across prediction markets. If you are trading across Polymarket, Kalshi, or Limitless, you need a unified API to avoid getting locked into a single exchange's ecosystem.<p>pmxt is stepping in to fill that void.
Scientists may have found the holy grail of quantum computing
Scientists may have spotted a long-sought triplet superconductor — a material that can transmit both electricity and electron spin with zero resistance. That ability could dramatically stabilize quantum computers while slashing their energy use. Early experiments suggest the alloy NbRe behaves unlike any conventional superconductor. If verified, it could become a cornerstone of next-generation quantum and spintronic technology.
Generative AI analyzes medical data faster than human research teams
Researchers tested whether generative AI could handle complex medical datasets as well as human experts. In some cases, the AI matched or outperformed teams that had spent months building prediction models. By generating usable analytical code from precise prompts, the systems dramatically reduced the time needed to process health data. The findings hint at a future where AI helps scientists move faster from data to discovery.
James Webb Space Telescope captures strange magnetic forces warping Uranus
For the first time, scientists have mapped Uranus’s upper atmosphere in three dimensions, tracking temperatures and charged particles up to 5,000 kilometers above the clouds. Webb’s sharp vision revealed glowing auroral bands and unexpected dark regions shaped by the planet’s wildly tilted magnetic field.
NASA’s Hubble spots nearly invisible “ghost galaxy” made of 99% dark matter
Astronomers have uncovered one of the most mysterious galaxies ever found — a dim, ghostly object called CDG-2 that is almost entirely made of dark matter. Located 300 million light-years away in the Perseus galaxy cluster, it was discovered in an unusual way: not by its stars, but by four tightly packed globular clusters acting like cosmic breadcrumbs.

Show HN: 17MB pronunciation scorer beats human experts at phoneme level
I built an English pronunciation assessment engine that fits in 17MB and runs in under 300ms on CPU.Architecture: CTC forced alignment + GOP scoring + ensemble heads (MLP + XGBoost). No wav2vec2 or large self-supervised models — the entire pipeline uses a quantized NeMo Citrinet-256 as the acoustic backbone.Benchmarked on speechocean762 (standard academic benchmark, 2500 utterances):
- Phone accuracy (PCC): 0.580 — exceeds human inter-annotator agreement (0.555)
- Sentence accuracy: 0.710 — exce
Show HN: Value of the Day – Rate your day with stars and reviews
I’ve just released "Value of the day" — An Experimental website project to rate each day with stars and reviews.The website functions like a collective diary, where the "value" of each day is determined by its average star rating and a repository of anonymous reflections.The calendar on each page displays the average star rating for that day, and once you've posted, you can click on the date to see the review details.

Ask HN: On-Device vs. Cloud Based LLMs
According to Claude, "the underlying infrastructure uses shared compute resources — many users' requests are handled across a pool of GPUs"What is the size of this pool, ie how many GPUs would it take for an individual user to be able to run their own equivalent today? Let's assume the LLM is fully downloadable.I ask, because, if LLMs stop improving exponentially, surely soon enough we will ALL be able to run un-quantised local LLMs of sufficient quality for day to day tasks.
