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

Cutting a photon in two creates an infinite swarm of particles
By definition, elementary particles can't be broken into smaller pieces. But in a new theoretical study published in Physical Review Letters, Johannes Skaar and colleagues have revealed what would happen if you tried anyway for a single photon. The answer is deeply strange: attempting to cut a photon in two wouldn't produce two smaller photons, but instead conjure an infinite number of them out of thin air.
A stellar “Rosetta stone” reveals the source of mysterious cosmic signals
Astronomers have finally cracked the mystery behind a strange class of repeating cosmic signals that has baffled scientists for years. Using Australia’s ASKAP radio telescope, researchers traced the bursts to a rare stellar duo in which a dense white dwarf is relentlessly siphoning material from a nearby red dwarf companion. As the stolen matter spirals inward, the system unleashes powerful radio waves and X-rays every 1.4 hours.
Show HN: Glq LLM quantization using E8 lattice
I have with the help of AI create an open source method of E8 LLM code book quantization library called glq. I was interested in creating Glq
as a PC gamer and devops, interested in both LLMs and AI. The current high RAM prices and LLM resource usage also inspired me to write glq. A question arises could you try and squeeze more out a gaming GPU with limited VRAM size by using alternative LLM compression methods?Glq is effective compared to other LLM quantization algorithms at between 2-bits per
Show HN: Opthash – Rust implementations of Elastic and Funnel hashing
I first came across the paper “Optimal Bounds for Open Addressing Without Reordering” through a Quanta Magazine YouTube video a few months back. I went looking for an official implementation and couldn’t find one, so I decided to try implementing the paper's Elastic Hashing and Funnel Hashing in Rust.To that end, I build opthash, a Rust library providing ElasticHashMap and FunnelHashMap implementations (and more recently HashSet variants). They are at API parity with std::collections::HashM
Show HN: Interpreto – Live Translation for Travel
I built Interpreto as a quick side project after getting frustrated with every translation out while travelling to Mexico and China.The problem I want to solve was making those four back-and-forth conversations when two people are sharing one phone. It uses the new GPT real-time translation and a split-screen UI for turn taking. It's incredibly fast at translating and currently supports a few languages.It's quite expensive right now which is why there's a subscription option if yo
Show HN: Manger – Livestock Management App
Hi HN,My name is Matt and I've been working on a project called Manger, a mobile app used for livestock management. As a child, I grew up in a rural area with chickens, cows and other livestock around me. At the same time, I've always been passionate about technology. About a year ago, I launched Manger on iOS, and, more recently on Android. Just this past week, I launched RFID tags for poultry, called "eFlock Smart Poultry Tags" along with a companion scanner. The "kill
Am I too pessimistic about Python's future?
Python was my main language for more than a decade. My unpopular opinion is that things started to go wrong with asyncio. It feels like a band-aid solution that required a whole new ecosystem to grow around it.Typing was a good idea, but I feel like it was never fully completed. So we ended up with optional typing, which definitely helps with reading code, but that’s about it. I see many features being implemented to speed up execution, along with attempts — some successful — to overcome the GIL
Show HN: Voice control coding agents on your machine via smartwatch / CarPlay
TLDR: got tired of my desk, so now I touch grass while coding from my watch.Ever since the 2021 GH Copilot beta saved me from dual carpal tunnel, I figured AI's main benefit in coding would be cutting typing while keeping productivity. That's turned out true; no one writes their own code lately. Why wouldn’t you have AI do the first draft? Why not your updates too? I expected phone coding to rise next, but tiny keyboards wreck your hands even faster. To put this into practice, I starte
Ask HN: What email API providers to use for pet project?
I'm building a pet project for a local community, and I need to send emails - potentially thousands of them. The project won't be commercial, so I'd like to spend as little money as possible. I'd also like to avoid hosting a custom SMTP server or dealing with all the setup.It seems like there are quite a few email providers on the market, but I'm not sure whether my project would meet their requirements.What would you recommend as a cheap and reliable(good deliverability
Show HN: Textile – A desktop app for weaving together bits of text
Hi all,I'm excited to show off Textile, a desktop app I recently built.Textile can combine bits of text using various inputs, such as commands on your computer, the contents of your clipboard, and hard-coded strings that you provide. It lets you carefully build up and modify a dynamic string, step by step, until it's exactly how you need it. The saved steps can then be executed on demand, with the click of a button or using a keyboard shortcut.I built Textile because I was often constr
Can Polymarket predict the progress of science, or are subject-experts better?

How Fast Are You Aging? New Genetic Clock May Have the Answer
A huge analysis of gene expression across species revealed genetic hallmarks of aging and could accelerate anti-aging treatments. There’s truth to the old adage, “Age is just a number.” People of the same age differ vastly in health and mental capabilities. One 80-year-old may be vibe coding with Claude, while another is gradually forgetting familiar faces and memories.To better gauge this difference, scientists have been developing “clocks” that measure biological age. Rather than the number of
New hydrogen breakthrough turns waste heat into clean fuel
A breakthrough hydrogen-production method could make clean fuel far cheaper and easier to generate. Researchers at the University of Birmingham developed a perovskite-based catalyst that splits water into hydrogen at much lower temperatures than existing technologies, potentially allowing factories, steel plants, cement works, and renewable energy sites to turn waste heat into valuable hydrogen.
New light-powered chip could accelerate AI and quantum computing
Scientists have created a tiny chip that can generate, steer, and read light-based information all in one device, marking a major leap toward ultra-fast, energy-efficient computing. The breakthrough uses atomically thin materials and nanoscale structures to control a unique quantum property of light called the “valley” degree of freedom, allowing information to be encoded in new ways.
Matter may entangle with light far more easily near quantum critical points
Quantum entanglement is a state in which particles are entwined with each other. In this entwined state, the properties of one particle influence the other, even when they aren't physically close to each other. This phenomenon has often been observed in small quantum systems with only a few particles in them, where researchers can use it to store and process quantum information. Rice University professor Qimiao Si is interested in understanding and applying quantum entanglement to macroscopic sy
