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
These ancient quasars shouldn't exist so soon after the Big Bang
Astronomers have uncovered 31 of the oldest known quasars, including the two earliest ever detected, shining from a time when the universe was only about 670 million years old. Powered by supermassive black holes billions of times the Sun’s mass, these incredibly bright objects challenge scientists’ understanding of how such enormous black holes formed so quickly after the Big Bang.
This Mars rover could finally reveal whether life ever existed on Mars
The hunt for ancient life on Mars just got an important test run. Scientists confirmed that the Rosalind Franklin rover's sophisticated instrument can detect subtle differences in two stable molecules that could preserve evidence of past life for billions of years. But the team also uncovered a surprise: organic molecules in the Murchison meteorite appear to have been contaminated by fossil fuel pollution during their journey through Earth's atmosphere.
Ask HN: Any Quantum Computer people who knows how to run a benchmark here?
I have a quantum circuit compilation pipeline validated on real quantum hardware (IBM Heron r2).- No heuristics, no simulation, no free-parameters.- It passed the IBM's 892 abstract transpilation tests in 75 minutes (Qiskit took 17 hours 15 minutes),- It was clone 200+ times on GitHub in about 3 months,- It is hardware-agnostic, fully analytic, and scale linearly up to 1M+ qubits (that is one million and above),- All benchmarks are documented, public, and 2 papers where published.Anybody ca
Scientists finally solved a 150-year-old gallium mystery
Scientists have rewritten the story of gallium after discovering that its unusual atomic bonds re-form at high temperatures, contradicting decades of accepted theory. The finding changes how researchers explain why the metal melts so easily and behaves unlike almost any other metal. Beyond solving a long-standing scientific mystery, the work could lead to advances in semiconductors, nanotechnology, and liquid metal engineering.
Harvard scientists turn a silicon chip into a DNA writing machine
Scientists have created a silicon chip that can write dozens of DNA sequences simultaneously using electricity and water-based enzymes, offering a cleaner alternative to conventional DNA manufacturing. The breakthrough could eventually support portable DNA-writing devices and even massive DNA data storage, although new chemistry will be needed to scale the technology further.
Heidelberg physicists just united two opposing quantum theories
A new quantum theory bridges two rival models of how impurities behave inside many-particle systems, resolving a problem that has challenged physicists for decades. The findings could reshape experiments on ultracold atoms, semiconductors, and other exotic forms of quantum matter.
Scientists used AI to crack one of water's biggest mysteries
Water’s odd behavior becomes even more dramatic when it is supercooled, but scientists have struggled to compare the many different ways of describing its microscopic structure. Researchers at the University of Osaka used an AI model trained on computer simulations to evaluate 16 different structural descriptors. The system identified the most effective ways to distinguish between water’s two competing liquid states, providing a clearer framework for studying one of nature’s most mysterious subs
Reinforcement learning control of quantum error correction
<p>Nature, Published online: 08 July 2026; <a href="https://www.nature.com/articles/s41586-026-10759-2">doi:10.1038/s41586-026-10759-2</a></p>By integrating reinforcement learning with quantum error correction, a quantum computer continuously self-calibrates during computation, achieving record logical error rates and enhanced resilience to drift.
Separating logic and language
Some people find it useful to talk through their problems — but language isn’t necessary for logical reasoning, cognitive neuroscientists at MIT’s McGovern Institute for Brain Research say. In research published this week in the journal PNAS, researchers led by MIT associate professor of brain and cognitive sciences Evelina Fedorenko have shown that people can perform well on tasks that require logical reasoning even if their language abilities are severely impaired. What’s more, brain imag

3 Questions: Searching for new physics with “beauty” particles
The Standard Model of particle physics is a well established theory that describes the fundamental particles and forces that govern the universe. Yet it cannot explain dark matter, the matter–antimatter imbalance, or gravity at the quantum scale, all of which suggest that additional particles and forces beyond the Standard Model may exist. One promising place to look for cracks in the Standard Model is in the decays of particles containing a type of elementary particle called the “beauty qu
Long-theorized electron-on-helium qubit achieves strong coupling to a single microwave photon
Quantum computers, devices that store and process information leveraging the principles of quantum mechanics, have been found to be promising for tackling some problems that cannot be solved by classical computers. Quantum computers store data in the form of qubits (i.e., quantum bits), units of information that can exist in combinations of different states, instead of being limited to a binary value (i.e., 0 or 1), like classical bits.
New AI model reveals how neutron star mergers forge heavy elements
Researchers have created an AI-based simulation that makes it much faster to model how neutron star mergers produce many of the universe's heaviest elements. The new tool could improve predictions of these powerful explosions while helping scientists better connect observations in space with experiments on Earth.

Show HN: Fast, native Mac file manager (filters, fuzzy find, 9 MB, no Electron)
My Downloads folder had been left unkept for a really long time and cleaning it up using Finder was quite cumbersome. So I started creating a simple app to help me filter out and delete or move the files in the folder.It started out very basic and the filtering options genuinely helped me clean out the Downloads folder, then as I thought of more features I would like to see in a file manager I started to add them. Some of the features are:- Fuzzy go to folder/file where you only need to wri
Opinion: Agents > Unix Shell
This is just something I've been thinking about. My experience is that agents aren't useful if you view them as programmers, because you still have to audit all the code until we get to the point where you don't, which may be quite far off.<p>But if you view them as a replacement/driver for the Unix shell, as much as I have loved it for many years, it does seem like you can move faster.
Show HN: A short walking sim based on 3DGS that runs in the browser
Hi! I built a free short walking sim you that runs in the browser.I originally made this experience about 2-3 years ago in Unreal Engine. The resulting build was huge: over 6 GB to download in order to play for max 10 minutes. Needless to say there weren't that many people that ended up playing the game.Seeing the quality that's possible to achieve nowadays in the browser using gaussian splats, I recently got the idea to port it to a web-based experience. The result is that the whole g
Ask HN: How do I find startups hiring developers for low pay and equity?
I know about Work at a Startup, YC job, and Wellfound jobs, but they haven’t really worked for me so far.I don’t mind if the pay is low as long as there is some equity involved, or even a mix of both. Are there any other job platforms or should I approach startup by myself ? I’m trying to find a role where I can use that experience while also learning more about the startup side.If you are a startup, how would you respond to that?I have 4+ years of experience working with React and Next.js, and
