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
15-year-old has a PhD in quantum physics and plans to 'create superhumans'
Laurent Simons, a 15-year-old Belgian researcher, has earned a PhD in quantum physics and says he plans to create "superhumans."
Scientists Discovered Light Follows Quantum Rules. It Could Change Physics.
It's long been known that the quantum Hall effect impacts electrons in strong magnetic fields, but it turns out light also follows the fundamental constant.
Inside the quantum loop: New tool cracks a long-standing physics mystery
Superconductors are among the most puzzling materials in physics. They conduct electricity with zero resistance, but only under specific conditions that researchers have struggled for decades to fully explain.

Tell HN: macOS supports instant snapshot rollbacks
I discovered this today and was quite surprised, so I thought I'd share.<p>You can obviously do a full reset and then use Migration Assistant on a backup. This might take a half hour and it's a hassle.<p>But you can also boot into recovery, go in "Restore from Time Machine", pick a recent snapshot (including hourly "local snapshots"), and roll back to it. It takes seconds (and a reboot) and your Mac is now rolled back to its previous state.
Show HN: Kagi alternative (simpler and EU-based) – Uruky
Hi HN! My wife and I have been working on Uruky for a few months now, a simpler EU-based Kagi alternative.This week we finally got our production API Key for EUSP/STAAN (it was certainly the slowest and most complicated search provider to adopt, so far), and that brought us to 5 search providers you can choose from and sort as you prefer.We already have got over 20 paying customers (excluding family and friends, we’re guessing these paying customers came from some privacy listings and HN co
Ask HN: Apple terminated our dev account over a rogue employee
I know that HN isn't a customer support forum and it might not be right to post this here, but we are absolutely desperate and hoping someone in this community can point us in the right direction.We are a small software company in Africa. For over two years, we've built and maintained an app. It has become a vital economic engine for our local community, employing a whole fleet of delivery agents and serving as a lifeline for local stores and restaurants.Recently, we discovered that a
Show HN: Refrax – my Arc Browser replacement I made from scratch
Open the same tab in two browser windows. In Chrome or Safari, you get two unconnected pages. In Arc, one window shows a placeholder. In Zen, it silently creates a duplicate.In Refrax, the browser I built, both windows show the same page updating live. The same web page, in as many windows as you want.This shouldn't be possible. WebKit's WKWebView can exist in exactly one view hierarchy at a time. With macOS 26, Apple added a SwiftUI API separating WebView from WebPage, so you can end
Ask HN: How do you handle PR density (and slop) in open source
Given that coding agents like Claude Code or Codex are now quite good, there's of course a massive increase in PRs submitted to open source projects. Not all of them are great, some are true AI slop.See for example Daniel Stenberg on the topic as it relates to cURL:

Quantum computers could have a fundamental limit after all
The performance of quantum computers could cap out after around 1,000 qubits, according to a new analysis published in the Proceedings of the National Academy of Sciences. Through new calculations, Tim Palmer at the University of Oxford has reconsidered the mathematical foundations underlying the quantum principles behind the technology, concluding that restrictions on the information-carrying capacity of large quantum systems could make their computing power far more limited than many researche
Superconducting quantum processor performs well with significantly less wiring
Quantum computers, computing systems that process information using quantum mechanical effects, could outperform classical computers on some computational tasks. These computers rely on qubits, the basic units of quantum information, which can exist in multiple states (0, 1 or both simultaneously), due to quantum effects known as superposition and entanglement.
Neutrality can speed up and stabilize collective decisions, new study shows
Trying to persuade people to abandon deeply held views often backfires, leaving groups entrenched and unable to move forward. A new study by researchers at the University of Bath in the UK proposes a strategy that is both surprising and more effective: encourage neutrality.
World’s first quantum battery could enable ultra fast charging
Scientists in Australia have demonstrated a prototype quantum battery that could revolutionize energy storage. By harnessing quantum effects, it can absorb energy in a rapid “super absorption” event, enabling much faster charging than conventional batteries. Even more surprisingly, the system becomes more efficient as it scales up. The research opens the door to ultra-fast, next-generation energy technologies.
Scientists twisted a mysterious superconductor and got a shocking result
A decades-old superconducting mystery just took a surprising turn. Strontium ruthenate, a material that conducts electricity with zero resistance at low temperatures, has long puzzled scientists with hints of an exotic, complex superconducting state. But by carefully twisting and distorting ultra-thin crystals, researchers found something unexpected: the material barely reacted at all. This challenges years of assumptions and suggests its behavior may be far simpler—or far stranger—than previous
This floating time crystal breaks Newton’s third law of motion
Scientists have created a new kind of time crystal using sound waves to levitate tiny beads in mid-air. These particles interact in a one-sided, unbalanced way, breaking the usual rules of motion and creating a steady, repeating rhythm. The system is surprisingly simple yet reveals complex physics with big implications. It could help advance quantum computing and deepen our understanding of biological timing systems.
TVs keep getting more pixels – but we are approaching the limits of what our eyes can actually see
Michael Maasen / UnsplashI remember sitting very close to the television as a child and seeing the image was made up of tiny coloured dots, each of which broke down into miniature vertical strips of red, green and blue when I looked even closer.Back then, a television was a bulky box that sat on its own stand. Today, screens are so thin they hang flat on the wall. At the same time, picture quality seems to improve every few years. Manufacturers promise sharper resolution, brighter images and ri
New quantum controls can stretch, blur, or reverse the arrow of time
Physicists have designed a set of quantum control protocols that can make a monitored quantum process look as though time is flowing backward, forward at a different speed, or in no clear direction at ...
