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

Dispatches from the possibly last days of human relevance
As most readers have presumably heard by now, Paul Erdös’s Unit Distance Problem from 1946—one of the central open problems from the field of discrete geometry—has been solved by GPT5.5Pro. Erdös had conjectured that, given n points in the plane, at most n1+o(1) pairs of them could be unit distance apart. Using high-powered results from algebraic number theory, GPT refuted this, constructing a set with n1+ε unit-distance pairs, for ε ~ 10-38. Shortly afterward, Will Sawin, a

ETH Zurich built an ultra-stable quantum gate across 17,000 qubit pairs
Quantum computing still stumbles on fragility, where tiny disturbances can wreck calculations. ETH Zurich researchers built a geometric swap gate with neutral atoms that stayed remarkably stable across 17,000 qubit pairs, hinting at a sturdier path toward large-scale quantum machines.
Brighter MRI signals
When doctors and scientists want to see inside a body, magnetic resonance imaging (MRI) is a powerful tool. MRI can noninvasively capture detailed images of the body’s muscles, organs, and bones. It can monitor blood flow to generate a map of brain activity. And with new sensors developed by bioengineers at MIT, MRI can track the kinds of molecules that make our brains and bodies work.In the May 13 issue of the journal Nature Biomedical Engineering, a team led by Alan Jasanoff, the Eugene McDerm

Q&A: How researchers are building next-gen quantum computers
Quantum computers have the potential to transform science, accelerating breakthroughs in drug development, cosmology, materials science, nuclear physics, and more.
Perfect randomness realized for the first time
Creating perfect randomness is surprisingly difficult. Even modern random number generators never generate completely ideal random numbers: small systematic errors can result in some numbers appearing slightly more frequently than others. For many applications, this does not matter. In cryptography, however, even the tiniest deviations can be problematic.
The strange quantum property of tomorrow's insulator
Ultra-fast data transfer and superconductivity: Quantum materials offer significant technological prospects—if we can understand them at the atomic scale. A team from the University of Geneva (UNIGE), in collaboration with the University of Salerno, the Institute of Materials Science of Barcelona, and the National Research Council of Italy, has succeeded in observing the "quantum metric" in a topological insulator—a unique geometric property of these materials, which conduct electricity only on
Did the Linux memory management maintainer "just quit"?
I came across this breathlessly written article, the beginning of which I will reproduce below, so as to not give its author any more engagement:Title: "Linux Memory Had One Maintainer for 26 Years. He Just Quit. Now What?"Subtitle: "One person held the code that runs every Android phone, cloud server, and supercomputer for 26 years. On April 21, he posted one message and then was silent."Last non-paywalled sentence: "Two weeks later, at a developer summit in Zagreb, the
Show HN: Kakeibo – a simple budget tracking app for simple people
Hey HN!For the past few years I've been following the kakebo/kakeibo method to track my expenses and savings. The term might be a bit obscure, but it's really simple: plan your monthly spending based on your income and fixed expenses; track your expenses and categorise them in one of 4 categories (needs, wants, culture, unexpected); at the end of the month, reflect on your spending: look at aggregates by category, spot trends… overall, just be a bit more conscious about where you
Show HN: Raft in Rust
For quite sometime, I’ve wanted to give implementing the Raft consensus protocol a try. I first looked at MIT’s 6.5840 Distributed Systems labs as a way to do this but it is in Go and my Go skills have atrophied as well as I have been deeply investing time in Rust. The other option was PingCAPs approach (https://github.com/pingcap/talent-plan/blob/master/courses/d...) but I also wanted the ability to define my own types and RPC approach, so I decided to do
