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: UK Butchers Meat Price Tracker

Hey all!Long time lurker, thought I would contribute back something to the community (at least the meat eaters in the UK). One thing that's been a pain for me to get a good understanding of is what the best price is for online butchers based around the UK. I like high quality meat (including some of the bigger cuts for kamado/bbq), and I'm willing to pay a premium however there isn't a single resource that would let me get an overview of what's available and price moveme

Show HN: I made a human-in-the-loop system for tuning LLMs in beta

OneShot is an API that routes failed LLM outputs to trained humans, returns corrected outputs or prompt injections, and stores the edits as structured training data.Privacy Note: This product is not built for privacy yet. The current use case is internal tools or beta features where users aren’t promised privacy. But the point of this tool is NOT FOR PRODUCTION.In the future, there will be a feature for anonymizing all private information automatically.Problem: My project this year was a tool fo

Ask HN: Feedback on OSS Project Idea

I want to learn c++, ultra low latency, and low level Linux internals through an OSS project that provides great value to its users. Aside from learning, the main purpose would be to provide a sense of accomplishment to me while doing good.I'm thinking of a utility that allows greatly reducing the network latency of any program on linux. It would do this by hooking the socket syscalls of the target program into its own implementations that utilize userspace networking. So a kernel bypass wi

Show HN: Hacker News Christmas Colors Browser Extension

I love the look of HN on Christmas Day, but I never feel like I get quite enough of it in just one day. To rectify this catastrophic problem, I created a browser extension to give me the Christmas HN experience from the day after Thanksgiving until the first work-day of the new year.I also added a fun "extra festive" mode that enhances the festivity level of the site beyond it's normal look. I love it, but I expect it to be controversial :-DIt's pretty easy to `git clone` a

A keyboard ring capable of alphanumeric output

Hello,Testing the waters here, as I just scored technical feasibility on this after working on it for a 2-3 years. Have to be shallow about the details as it is being patented.I have designed a keyboard ring capable of silent typing using HID only. The raw data is processed by an AI system delivering the complete sentences to the host device clipboard or in the companion app. I got the hardware working, but have not yet decided on the software layer.The product while worn was originally meant to

AI finds a hidden stress signal inside routine CT scans

Researchers used a deep learning AI model to uncover the first imaging-based biomarker of chronic stress by measuring adrenal gland volume on routine CT scans. This new metric, the Adrenal Volume Index, correlates strongly with cortisol levels, allostatic load, perceived stress, and even long-term cardiovascular outcomes, including heart failure risk.

Astronomers watched a sleeping neutron star roar back to life

Astronomers tracked a decade of dramatic changes in P13, a neutron star undergoing supercritical accretion. Its X-ray luminosity rose and fell by factors of hundreds while its rotation rate accelerated. These synchronized shifts suggest the accretion structure itself evolved over time. The findings offer fresh clues to how ultraluminous X-ray sources reach such extreme power.

Webb finds a hidden atmosphere on a molten super-Earth

Webb’s latest observations reveal a hellish world cloaked in an unexpected atmosphere: TOI-561 b, an ultra-hot rocky planet racing around its star in under 11 hours. Despite being blasted by intense radiation that should strip it bare, the planet appears to host a thick layer of gases above a global magma ocean, making it far less dense than expected.

UK quantum networking start-up Nu Quantum raises $60m

Nu Quantum plans to use the funding to accelerate its quantum entanglement roadmap, expand its teams and fuel its global growth.

IBM Unveils Quantum Roadmap, Plans 1,000-Qubit Chip by 2023

IBM is one of the companies jockeying for position in the nascent field of quantum computing and the company thinks it has a roadmap to develop a universal quantum computer with up to 1,000 qubits.

New quantum antenna reveals a hidden terahertz world

Researchers at the University of Warsaw have unveiled a breakthrough method for detecting and precisely calibrating terahertz frequency combs using a quantum antenna made from Rydberg atoms. By combining atomic electrometry with a powerful terahertz-to-light conversion technique, they achieved the first measurement of a single terahertz comb tooth—something previously impossible due to the limits of electronics and optical tools.

A clear new material could make windows super efficient

MOCHI uses microscopic, air-filled channels to stop heat in its tracks while remaining nearly crystal clear. If scaled up, it could transform windows into powerful energy savers and solar harvesters.
