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: Open Passkey – open-source passkey auth with free "backendless" host

I, like Andrej Karpathy, became super frustrated by how annoying it was to deploy projects that were previously an absolute joy to make with Claude Code. That is why I made open-passkey, an MIT licensed passkey repo with support for 33 languages and frameworks (examples included) that makes adding simple secure auth to a project easy.We are also releasing gateway (https://gateway.locke.id) a "backendless" hosted auth server that frontend apps can consume for free so that you

Why Rigetti Computing (RGTI) Is Up 34.9% After Launching Its 108-Qubit Cepheus-1-108Q System

In early April 2026, Rigetti Computing announced the general availability of its Cepheus-1-108Q system, a 108-qubit modular quantum computer accessible via Rigetti Quantum Cloud Services and Amazon Braket, featuring 12 interconnected 9-qubit chiplets and median two-qubit gate fidelity of 99.1% with ~60 ns gate speeds. By tripling the qubit count of its prior Cepheus-1-36Q system and introducing chiplet, control electronics, and fabrication advances aimed at scalable error-corrected...

RoboticsPhysical Intelligence, a Hot Robotics Startup, Says Its New Robot Brain Can Figure Out Tasks It Was Never TaughtConnie Loizos | TechCrunch“Physical Intelligence, the two-year-old, San Francisco-based robotics startup that has quietly become one of the most closely watched AI companies in the Bay Area, published new research Thursday showing that its latest model can direct robots to perform tasks they were never explicitly trained on—a capability the company’s own researchers say c

Mental math's shortcut—pupil dilation suggests people start solving before all numbers are in

People often solve simple arithmetic problems, such as basic addition, subtraction, multiplication or division, in their minds. The precise mental processes they rely on to solve these problems, however, are not entirely clear. Researchers at Université de Bordeaux and UCLouvain recently tried to better understand how humans tackle simple math mentally by tracking the size of their pupils.

Black hole jets measured for first time and rival the power of 10,000 suns

Scientists have captured stunning new insights into one of the universe’s most powerful phenomena—black hole jets—by using a planet-sized network of radio telescopes. Focusing on Cygnus X-1, one of the first known black holes, they measured jets blasting out with the energy of 10,000 Suns and moving at half the speed of light. By watching these jets get pushed and bent by the fierce stellar winds of a nearby supergiant star, researchers could calculate their true power for the first time.

Universal quantum protocol extracts maximum work without knowing a system's state in advance

A new study published in Nature Communications has shown that in the asymptotic limit, extracting the maximum possible work from many copies of a quantum system does not require knowing exactly what state that system is in.

Show HN: Marky – A lightweight Markdown viewer for agentic coding

Hey HN,In this age of agentic coding I've found myself spending a lot of time reviewing markdown files. Whether it's plans or documentation that I've asked my agent to generate for me, it seems that I spend more time reading markdown than code.I've tried a few different solutions to make it easier to read such as Obsidian however I've found their Vault system to be quite limiting for this use case and I've found TUI solutions to not quite be as friendly to read as I
