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
The 50-year quest to create a quantum spin liquid may finally be over
For minerologists, a mine is an invitation. The earth has been broken open, its veins laid bare – and those who enter hope to find unknown wonders. In the 1970s, Kali Kafi mine near the small Iranian ...

Quantum technologies, devices and systems that process, store, detect, or transfer information leveraging quantum mechanical effects, have the potential to outperform classical technologies in a ...
New chip harnesses quantum computing's biggest weakness — and tries to turn it into a strength
A new quantum computing chip turns destructive noise into a programmable feature, helping scientists study signal loss and ...
Show HN: Git-lazy-mount mount a repo without cloning it. Works with ordinary Git
Hello!This is an attempt to make google3 style repo clones work with Git. In a HN thread a few days ago the idea sparked for me.It can be super useful for very large repos that need to be cloned for AI coding sessions that might only need a subset of files to accomplish something.Similar to google3, files appear to be there and can be read and edited but they are only fetched when they are needed.It works with normal Git commands so there is no need for a new CLI.On huge catch is, running grep w
Show HN: ShotBrief – Daily photography briefings, should you shoot tomorrow?
I had a n8n workflow running for quite a while that would send my these briefings on Telegram, telling me the photography conditions tomorrow, if I should bother going out or not (I go by weather a lot).<p>Turned that into ShotBrief.
Show HN: Cyclearchive.com – search vintage cycling magazines
Hi HN, Cycle Archive is a free, browsable library of old cycling magazines and books from the 1860s–1940s.
I started it as a way to explore cycling history myself, and all of the weird and wonderful articles in there. People inventing brakes, fighting about wheel sizes, pioneering indoor training and some pretty questionable dietary and training advice!The site attempts to pull it all together somewhere you can actually sit and read it. (Almost) every issue has a generated contents list: article
Show HN: Discover content in any YouTube channel with RAG
Ask Channel AI (http://askchannel.ai) allows you to quickly find relevant videos, quotes, and timestamps from any YouTube channel.Channels that are not yet indexed or imported can be done so by signing up, and imports are typically pretty fast for small to medium sized channels (~1 minute). Channels are the first-class citizen instead of individual videos, since summarization of individual videos is already a thing in YouTube.---I spend a lot of time watching and listening to long-form
Show HN: Luma – A New Workspace for Frida
Hi HN! I'm the creator of Frida.<p>I'd like to share Luma, a new workspace for Frida that I've been working on for quite a while.<p>The goal is to bring together the workflows I kept bouncing between while reverse engineering and instrumenting applications: persistent workspaces, an interactive REPL, `frida-trace`, collaboration, and more, in a single application.<p>It runs on macOS, iOS, Linux, and Windows, and it's open source.<p>Happy to answer any questions.
Show HN: Engye – transfer files between any two devices by scanning a QR code
Early in April I needed to print some tax forms at the library, first time in forever, and I began to wonder: what's the easiest way to get a file onto a public computer?There are many ways, but most of them involve creating an account somewhere or plugging in a thumb-drive. I use a password manager, so my passwords are long and complicated, not easily typed. I don't want to plug anything into a public computer, nor do I fancy uploading my taxes to some random website.I thought about w
Yellowstone’s supervolcano may be fueled by something unexpected
Scientists have uncovered a new explanation for what powers Yellowstone and other supervolcanoes. Instead of a deep plume rising from near Earth’s core, a broad “mantle wind” may push hot rock beneath Yellowstone, generating magma closer to the surface. This process helps create a massive underground magma network and may explain how supervolcanoes remain active for long periods.
A rare supernova peeled back a star’s layers and revealed a hidden secret
Astronomers studying the rare supernova SN 2021yfj discovered material from one of the deepest layers of a dying star, providing a rare look at its hidden interior. The finding confirms key theories about how massive stars forge the elements that help build planets, worlds, and life.

ComputingIBM Has Unveiled Chip Technology That Could Help Extend Moore’s Law Another DecadeSophia Chen | MIT Technology Review ($)“To fit more transistors on a chip, engineers across the industry are eyeing a pivot to an approach familiar to urban planners: build up. On Thursday, IBM announced it has created a chip that uses this strategy. The new architecture, known as a nanostack, vertically stacks transistors in two layers on a silicon chip.”Artificial IntelligenceAI Is Designing
