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

Launch HN: Stoa Markets (YC S26) – A Marketplace for GPUs and AI Servers

Hi HN, we’re Eren, Berat and Kaan. We’re building Stoa (https://www.stoaexchange.com), a marketplace for new and used GPUs and AI servers.GPUs are the collateral in the data center buildout. Today, financing terms mostly depend on the offtaker, meaning the company that has committed to use the compute.If that company is a hyperscaler, the financing can look investment grade. If it’s a smaller cloud or startup, terms get expensive fast, even with the same hardware as collateral.The lend

On the hunt for dark matter

Physicists across the globe are on a quest for a particle that makes up nearly 85 percent of all matter in the universe, yet no one has ever directly detected it. Jessica Fry, a fifth-year physics PhD candidate in the Laboratory for Nuclear Science (LNS), is one such hunter.Fry grew up in the San Francisco Bay Area, not far from the SLAC National Accelerator Laboratory. She began dancing at age 3 and by elementary school was competing nationally. On her office desk sits a photograph of her

Monochrome No More: New Night-Vision Glasses Show Color

The system combines quantum dots and an OLED display, translating infrared light into a range of visible colors. Night-vision technology has changed little for decades, producing grainy green images that make it difficult to distinguish objects and depth. Now, researchers have developed a system that converts infrared light into color images.Standard night-vision goggles amplify the scant light available and convert it into monochrome green images that only vary by brightness. This is not a good

When it comes to predicting people's preferences, it pays to consider 'the power of three'

In his 1927 paper, "A law of comparative judgment," the American psychologist L. L. Thurstone proposed that when people select one option among multiple alternatives, they are picking the one that has the highest value to them, even though they cannot assign a particular number to that choice.

Quantum heat circuits learn electronics' oldest trick: Sharing a power supply

Every electronic and optoelectronic device generates heat, and today that heat is managed almost entirely from the outside. Heatsinks, fans, cold plates and refrigerators are bulky exterior measures bolted onto a chip or package after the fact. They treat heat as a single averaged quantity to be removed in bulk, even though the heat is actually produced locally, component by component, deep inside the circuitry.

Discovery of 'slow' electrons in 2D material could lead to new memory device

Over the last decade, researchers have developed two-dimensional materials with fascinating quantum effects that could be harnessed for next-generation technologies.

Show HN: A tool to auto-generate .vscode/settings.json and extensions.json

Hello HN,I built a tool that automatically generates .vscode's settings.json and extensions.json.## Why I built thisAt my job, our project didn't have a properly set up dev environment, and each developer managed their own .vscode settings individually. I felt this was hurting PR review efficiency due to formatting differences and similar issues.We were allowed to use Claude Code, but .vscode is treated as a protected directory, so it wouldn't reliably create or update these files

Show HN: Run your GitHub Actions locally or self-hosted in isolated microvms

Hey HN. I've been frustrated with Github Actions' reliability, and inability to run workflows locally. Preloop is a Rust reimplementation of the GitHub Actions, both the runner(tracking the latest version) and the control plane that runs in hardware-isolated microvms on MacOS/Linux/Windows(we use smolvm project that uses the libkrun vmm).The microvms starts in <400ms from a packed artifact, and cow-clones for each job are instant. The control plane speaks the exact officia

Show HN: Mail Attachment Lens: A Browser extension to manage Gmail attachments

Recently, I was getting close to Google’s free storage limit, and the storage manager showed that Gmail was using most of it.I wanted a simple way to see my attachments in one place, download the files I wanted to keep, and remove emails with attachments I no longer needed. Gmail search can find emails with attachments, but it doesn’t provide a convenient file-based view.So I built a browser extension called Mail Attachment Lens. It lets me search and filter attachments, download files, and move

Show HN: Voice driven murder mystery, Interview AI suspects with your voice

Hey HN!I'm excited to show off this really fun project I put together. I originally built this project 2-3 years ago, AI was already booming at the time, however voice AI agents were still very early. I loved my proof of concept at the time, but wasn't quite happy with it.I recently had the desire to check out the tech again, and know many of you will be interested.Interviews are speech to speech with OpenAI's gpt-realtime-2.1 over WebRTC. This model is... expensive, and because o

Scientists discover a hidden switch inside silver nanocatalysts

Silver nanocatalysts have been found to switch where they perform their most important reactions depending on whether a solid oxide cell is making electricity or hydrogen. The discovery could enable smarter catalyst designs that boost clean power generation while making green hydrogen more energy-efficient.

The sun will vanish over Europe in a rare total solar eclipse: Watch live

A total solar eclipse will plunge parts of Europe into darkness on August 12, 2026, with Spain offering some of the best views. ESA will livestream the spectacle from the Javalambre Observatory, combining telescope feeds, drone footage, and expert commentary. At 20:31 CEST, the observatory will experience 1 minute and 21 seconds of totality, revealing the Sun’s normally hidden outer atmosphere.

Voyager 2 was running out of power. NASA just bought it more time

NASA engineers have found a clever way to squeeze more life out of Voyager 2, nearly half a century after it left Earth. In an operation nicknamed the “Big Bang,” the team simultaneously shut down certain power-hungry hardware and switched to lower-power alternatives while keeping the spacecraft warm enough to survive.

Cassini reveals a surprising twist in Saturn’s magnetic shield

Cassini data has revealed a surprising twist in Saturn’s magnetic shield: the planet’s rapid rotation appears to drag a key opening in its magnetosphere far toward the afternoon side instead of keeping it near noon, as happens on Earth. The finding confirms that giant planets like Saturn operate under a fundamentally different magnetic regime, where fast spin and charged material from moons such as Enceladus can overpower the Sun’s influence.

Sunlight-powered setup generates quantum entanglement

Today's quantum technologies rely on energy-intensive lasers, raising concerns that scaling them up could further increase ...

University of Ottawa scientists produce quantum entanglement using sunlight

Sunlight produced entangled photons in an outdoor experiment, challenging the belief that these quantum links require carefully controlled lasers. The photon pairs closely matched an ideal entangled state and displayed correlations that classical physics could not fully explain.

Chemists set electrons free and break a decades-old chemistry barrier

Chemists have developed a catalyst that breaks a long-standing rule governing which molecules receive electrons during chemical reactions. By releasing electrons directly into solution, the technique could unlock reactions—and potentially useful new molecules—that were previously out of reach.

A 0.42-nanometer breakthrough could push transistors beyond silicon

Atomically thin semiconductors could enable dramatically smaller and more efficient chips, but a stubborn problem at the boundary between materials has limited their performance. Researchers have now engineered that atomic interface to protect electron flow while still allowing extremely thin insulating layers. The resulting transistors delivered an unusually strong combination of electrical control and performance.
