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

A Quantum Leap for the Turing Award

Charles Bennett and Gilles Brassard pioneered quantum information theory. Now they’ve been awarded the highest honor in computer science.

HKU Engineering researchers discover quantum entanglement accelerates quantum simulation

Researchers from the Faculty of Engineering at The University of Hong Kong (HKU) have made a significant discovery regarding quantum entanglement. This phenomenon, which has long been viewed as a ...

Scientists just found a hidden 48-dimensional world in quantum light

A routine quantum optics technique just revealed an extraordinary secret: entangled light can carry incredibly complex topological structures. Researchers found these hidden patterns reach up to 48 dimensions, offering a vast new “alphabet” for encoding quantum information. Unlike previous assumptions, this topology can emerge from a single property of light—orbital angular momentum.

A new entanglement-enhanced quantum sensing scheme

Over the past decades, quantum scientists have introduced various technologies that operate leveraging quantum mechanical ...

Show HN: Skillcop: Block malicious Claude Skills before they execute

I've been wanting to adopt more skills in my agent workflows, but I've been super sketched as a security person. There's marketplaces like Skills.sh and a ton of stuff on Github, but I felt like a lot of it was too untrustworthy to just be pulling down.Combined with Snyk reporting that they found ~1500 malicious skills on such marketplaces (https://snyk.io/blog/toxicskills-malicious-ai-agent-skills-c...), I decided to build a library for doing skill scanning si

How we are looking for cofounders is stupid

I have literally talked to hundreds of potential cofounders in the past year, some with awesome skill sets, some with access to millions in funding, and some who were wizards with social.None of that stuff matters guys! at least not as a first filter for finding a cofounder. What matters to a new startup more than anything else is energy/chemistry, working with someone you like a little bit is almost guaranteed to kill your startup. The first big issue you have, one of you will give up or y

Show HN: Agent Use Interface (AUI) – let users bring their own AI agent

As I started building AI integrations, I came to realize that for many projects, the the best agentic experience is one that simply enables the user's personal agent to take actions within your app.The existing options like MCP or A2A are quite involved and for simple apps that are already URL parameter driven, those options seem like overkill.This led me to prototype the Agent Use Interface (AUI) spec.The idea is simple: a lightweight, open spec that makes any app "agent-navigable.&qu

This Week’s Awesome Tech Stories From Around the Web (Through March 21)

Artificial IntelligenceOpenAI Is Throwing Everything Into Building a Fully Automated ResearcherWill Douglas Heaven | MIT Technology Review ($)“The San Francisco firm has set its sights on building what it calls an AI researcher, a fully automated agent-based system that will be able to go off and tackle large, complex problems by itself. ​​OpenAI says that the new goal will be its ‘North Star’ for the next few years, pulling together multiple research strands, including work on

Harvard engineers build chip that can twist and control light in real time

Scientists at Harvard have built a miniature device that can twist and tune light in real time. By rotating two stacked photonic crystals and adjusting their spacing with a tiny mechanical system, they can control how light’s “handedness” behaves. This allows the chip to distinguish between left- and right-circular polarized light with remarkable precision. The advance could lead to smarter sensors, faster communications, and new quantum technologies.

Physicists find electronic agents that govern flat band quantum materials

Physicists have directly visualized the fundamental electronic building blocks of flat-band quantum materials, a class of systems in which electron motion is effectively quenched and strong interactions give rise to emergent phases of matter. In a study published in Nature Physics, Qimiao Si's group at Rice University, in collaboration with researchers at the Weizmann Institute of Science, identified compact molecular orbitals that act as the key electronic agents governing the exotic behavior o

Prior art and simulation results for a non-von Neumann coordination

Two months ago I posted a public origin record for PRCA.https://news.ycombinator.com/item?id=46728770Two updates since then:1. Prior art formally registered via Zenodo. Three documents now have DOIs.2. Ran quantitative simulations based on the implementation guide. Results and analysis report here: https://doi.org/10.5281/zenodo.19128851 One number from the simulation I didn't expect: At N=25,000, Von Neumann synchronization overhead reach

Google DeepMind Plans to Track AGI Progress With These 10 Traits of General Intelligence

There’s plenty of hand-waving around AGI. DeepMind hopes to change that with a new, more rigorous approach. Few terms are as closely associated with AI hype as artificial general intelligence, or AGI. But Google DeepMind researchers have now proposed a framework that could more concretely measure how close models are to this tech industry holy grail.Artificial general intelligence refers to a mythical AI system that can match the general and highly adaptable form of intelligence found in h

New controls can stretch, blur and even reverse quantum time flow

In new research published in Physical Review X, scientists have designed quantum control protocols that generate processes more consistent with time flowing backward than forward. The protocols—techniques to control quantum systems—modify a quantum system's "arrow of time," the concept of time as moving in one forward direction. The work opens up possibilities for energy extraction from quantum systems and for quantum state preparation.
