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

Scientist creates 'mini‑universe' to measure time without a clock

A University of Birmingham scientist has built a "mini-universe" that takes a step toward answering one of science's biggest questions: "What is time?" Publishing his findings in Physical Review Research, Professor Giovanni Barontini shows how it is possible to measure the flow of time without using a clock at all. The new findings provide a scientific model in which a version of time emerges from the experiment itself.

Is Richard Dawkins Right About Claude? No. But It’s Not Surprising AI Chatbots Feel Conscious to Us.

Why do we see AI chatbots as more than what they are, and how do we stop? In May, evolutionary biologist Richard Dawkins wrote an op-ed suggesting AI chatbot Claude may be conscious.Dawkins did not express certainty that Claude is conscious. But he pointed out that Claude’s sophisticated abilities are difficult to make sense of without ascribing some kind of inner experience to the machine. The illusion of consciousness—if it is an illusion—is uncannily convincing:“If I entertain suspicion

These tiny holes could change how the world cleans water

A new nature-inspired membrane uses perfectly uniform one-nanometer pores to filter molecules with remarkable precision. The technology could transform industries such as pharmaceuticals and textiles by reducing energy consumption, improving water reuse, and delivering separation performance far beyond current filters.

Giant underground neutrino detector brings scientists closer to cracking the neutrino puzzle

Deep beneath the ground in China, the massive JUNO neutrino observatory has delivered its first major scientific breakthrough, achieving one of the most precise measurements yet of how elusive neutrinos change as they travel. Using just 59 days of data, researchers sharply improved measurements of key neutrino properties, boosting confidence that JUNO can tackle one of particle physics' biggest mysteries: determining the true mass hierarchy of neutrinos.

Engineering quantum Hall stripes in 2D materials inside electromagnetic cavities

Quantum materials, materials with properties that are governed by the laws of quantum mechanics, have proved to be highly promising for the development of ultra-efficient electronic devices, quantum processors, highly precise sensors and various other technologies. Reliably controlling these materials' quantum phases would be highly advantageous, as it would enable engineers to tailor and optimize their properties for specific applications.

Brain-inspired chip runs near absolute zero and could transform quantum computing

Scientists at the University of Hong Kong have created a remarkable new type of brain-inspired chip that can function just above absolute zero, one of the coldest environments imaginable. By using a standard silicon carbide transistor in a completely new way, the team made a single device behave like an energy-efficient neuron, firing electrical “spikes” similar to those in the human brain.

Show HN: AuthAI, an open-source relay for user-authorized AI sessions

Hello HN,My name is Riccardo and I created AuthAI for indie hackers.The idea is quite simple: let the end users connect their chatgpt/grok/copilot account and route the AI requests through their AI subscriptions.This enable a lot of new cool ideas where the business model/unit economics don't always make sense.The flow is straightforward:They click on "login with AI", choose their provider, and authorise the device on the provider's website.Tokens get encrypted

Show HN: Stochastc Unit Commmitment Using Genetic Algorithm

Hey everyone, in the last weeks I've been thinking about building a power market simulation engine that is not based on any linear or mixed-integer programming paradigm because these are hopeless when faced with making decisions under uncertainty. I've built a demonstratotr using julias out of the box genetic algorithm and I am quite fascinated by how far one can push this.I've modeled europes core powermarkets,connected via and PTDF approximation, fed with real-ish data. Number o

Why would someone want to learn code when AI does it better and faster?

I know it sounds like I'm some sort of self-taught "prompt engineer" but actually I spent some time learning to code, and a mistake I made was focusing too much on learning different frameworks and syntax etc etc. But it's impossible to consistently program and only learn syntax and no problem solving. So I learned a bit that too. But it hurt me very bad when I found out, not only AI is better than me in syntax, so it is in problem solving (however I sometimes catch their mis

Show HN: Claumon – forecasting Claude Code usage limits with a Gamma process

Anthropic's usage analytics dashboard is only available to Team and Enterprise org admins. On a Pro or Max plan all you get is /usage and the claude.ai usage page, which show where you stand right now but not where you're heading. I looked at various open-source projects but none quite matched what I had in mind: an all-round control panel for Claude Code that's also a single binary, with no dependencies and no install steps.The other thing I cared about was forecasting the u

Why are there an increasing number of outright unhinged high karma users on HN?

I’ve been noticing this disturbing trend for quite a while. By high karma I mean well over 1000 karma.And some of these leave comments so bizarre, that I can’t find any charitable explanation.Other than perhaps they may be skipping reading every other word or something… and then respond to an imaginary version of the parent.Uncharitably, they could be semi-random keyboard bashing, deranged bashing, emotional tantrums, and so on. Or LLM written… except the style doesnt match.Of course this has al

Show HN: A habit tracker for people who keep quitting their hobbies

I'm Mark, a 19-year-old student that once found himself clueless on how to keep up with different hobbies and passions. Like most people, I'd start strong and fade out within weeks. I noticed streaks worked incredibly well for me personally, I'm at 900+ days on Duolingo, so I built StreakUp around that idea, making every habit a streak. Built with Flutter, been working on it for 2-3 years since I was 16. Just hit 200 users. On the tech side, this project allowed me to see how much

One-way quantum synchronization could make quantum computers more reliable

Scientists at RIKEN have proposed a new way to make quantum systems synchronize in only one direction—like a one-way street for sound particles known as phonons. The breakthrough combines two quantum effects to create a form of one-way quantum synchronization that remains surprisingly stable even when exposed to manufacturing flaws and environmental noise, two major obstacles that have long hindered real-world quantum technologies.

AI Is Advancing Faster Than Our Ability to Understand It, Researchers Warn

While we still can’t explain how AI works, algorithms are rapidly learning what makes us tick. And the gap is widening. AI is becoming more powerful, and mysterious.Despite years of work on “explainable AI,” today’s most advanced systems remain black boxes for the most part. Scientists can observe what they do but cannot fully explain how they arrive at their conclusions or predict when they’ll fail.As large language models (LLMs), the algorithmic engines behind pop
