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

Quantum and quantum-like effects across neuroscience
Due to its apparent biological implausibility, the idea that quantum effects might be functionally relevant in neuroscience has been widely dismissed. Nevertheless, in recent years evidence that is consistent with this quantum brain hypothesis has been accumulating from diverse subfields of neuroscience. These range from theoretical and experimental results pertaining to anesthetic mechanisms, and non-standard MRI measurements reflecting consciousness at the whole-organism level, down to results demonstrating remarkable physical properties of microtubules at the subcellular level.In parallel with these developments on the biophysical side of the field, a burgeoning quantum cognition literature has developed describing how aspects of quantum theory appear well-suited for a rigorous quantitative statistical description of a wide range of behaviors in psychology. The behavioral results are striking and robust enough that researchers have begun to consider potential neural implementations for generating quantum-like cognition.This Topic aims to collect studies reflecting the current state of the art relevant to potential quantum effects operating in brain cells, and quantum-like effects at the level of behavior, in order to survey the range of current evidence relevant to quantum and quantum-like functions of the brain. Because the focus of this collection is neuroscience, theoretical/modeling studies are appropriate if they address neural mechanisms.· Computational and/or exp...
Quantum entanglement explained - How does it really work?
In this video, we delve into quantum entanglement, famously described as “spooky action at a distance” by Albert Einstein.
Show HN: Redos-analyzer – static ReDoS detection and auto-fix for Python
At 13:42 UTC on July 2, 2019, an engineer working for Cloudflare made changes to the regular ruleset that was being used by their Web Application Firewall. In under three minutes, there was an 80% drop in the amount of traffic globally. The load on all HTTP serving CPUs in their network hit 100%. It was caused by one regular expression intended to detect XSS attacks, which contained the regular expression pattern `.(?:.=.)`. This pattern included two quantifiers using `.` on the same character c
Show HN: I built an app using Apple Watch's water and HR sensors to track baths
Hey HN! First Show HN for me - niche app, but I think it nails something that hasn't been done properly before.Furolog (フロログ — furo = bath, log = logging) is an iOS + watchOS app that uses the Apple Watch underwater temperature sensor to automatically track onsen, sento, and sauna sessions. Everything runs and is stored locally.How it works: The core is an algorithm built on CMWaterSubmersionManager, heart rate, and motion data that detects whether you're bathing, resting, or in a saun
Show HN: Jbofs – explicit file placement across independent disks
Hey all,I created `jbofs` ("Just Bunch of File Systems") as an experiment to workaround some recurring issues I have run into
with suprising filesystem performance.My use case is storing large media (think pcaps, or movie files), where some hierarchal organization is still useful.Whether it’s NFS mounts (and caches), ZFS, or RAID (mis)configurations, I’ve run into surprising(ly bad) performance on
many occasions. Doubtless this is largely user error, but it can be hard to diagnose what
Show HN: Opensidian: Local-first notes in the browser with POSIX shell and sync
Hey HN! Braden here. Some of you might know me from Whispering a while back (https://news.ycombinator.com/item?id=44942731).Obsidian was one of the biggest inspirations behind the Epicenter project. I used it daily and think it's incredible software. But it's not open source, and Obsidian Sync never quite worked the way I wanted it to. I think any tool that sits this deep in your personal knowledge system should be open source and auditable.So I built Opensidian as an op
I don't want an autonomous AI agent. I want a collaborator
I’ve been using Cursor, Claude, and others quite a bit and I keep hitting the same pattern. The tool really wants me to step aside. I hand it a task, it vanishes, edits a bunch of files, and comes back with a fat diff. Then I’m supposed to reverse-engineer what it did, tie it back to what I intended, and fix what’s not right if I can spot it. It works pretty well a fair amount of the time, but it's not my work. Giving the LLM enough instruction to narrow that gap is more effort than just wr
Ask HN: How do you promote apps which are vibe coded but has real life usecase?
I am quite keen on developer tools, built some tools for developer productivity. But when I post about the app on the reddit (or other place), I don't get interaction instead getting more harsh comments about being vibe coded. In some cases, people are not even opening my app's website, rather just commenting like a bot about being vibe coded or having text using LLM.It was not like that, 2 years ago, any packages I created (more simple but useful), I posted on reddit and people shared
Show HN: PromptJuggler – A dev env and runner for prompts, workflows, agents
Backstory: At work I had to build an AI pipeline to run millions of prompts. First I just put the prompts into string consts and integrated directly with api, chaining one run onto the output of another – but it quickly became a maintenance nightmare. Iterating on prompts, testing them over datasets, experimenting with different chaining did not fit into the regular sdlc and running them at our scale was quite difficult as most of the time is spent on waiting for the api response while holding o

Something just hit the Moon and left a bright new scar
For all its ancient, familiar features, the Moon is still changing—and sometimes in dramatic ways. Scientists recently identified a fresh 22-meter-wide crater by comparing orbital images taken years apart, revealing a relatively recent impact that no one actually saw happen. The collision blasted bright material outward in striking rays, making the new crater stand out sharply against the darker lunar surface.
Did a black hole just explode? This “impossible” particle may be the evidence
A bizarre, record-breaking neutrino detected in 2023 may have originated from an exploding primordial black hole—a relic from the early universe. Scientists suggest these black holes could carry a mysterious “dark charge,” causing rare but powerful bursts of energy that current detectors might occasionally catch. This could explain why only one experiment saw the event. The theory also opens the door to discovering entirely new particles and possibly uncovering the nature of dark matter.
This walking robot could change how we search for life on Mars
Planetary exploration may be about to get a major speed boost. Researchers tested a semi-autonomous robot that can move from rock to rock, analyzing each without waiting for human instructions. The system completed missions up to three times faster than traditional methods while still accurately identifying important geological targets. This could allow future missions to cover far more ground in the search for resources and signs of life.
Quantum computers keep losing data. This breakthrough finally tracks it
Quantum computers struggle with a major flaw: their information vanishes unpredictably. Scientists have now created a new method that can measure this loss over 100 times faster than before. By tracking changes in near real time, researchers can finally see what’s going wrong inside these systems. This could be a big step toward making quantum computers stable and practical.
Scientists just uncovered the secret behind nature’s “proton highway”
Scientists have zoomed in on how phosphoric acid moves electrical charges so efficiently in both biology and technology. By freezing a key molecular pair to extremely low temperatures, they found it forms just one stable structure—contrary to predictions. This structure relies on a specific hydrogen-bond network that may be universal in similar systems. The discovery helps explain how protons travel so quickly and could inspire better energy materials.

Elon Musk, Quantum Microtubules, and the Race for the Conscious Machine
A recent Quanta Magazine piece by John Pavlus examines a burning question: how close are humanoid robots to becoming more sophisticated than humans? While neural networks on fast GPUs have turbocharged computer vision and reinforcement learning, allowing robots to perceive environments better, a massive gap remains between "moving" and "being."Engineers have moved beyond the "linear inverted pendulum" model, using deep reinforcement learning to act as whole-body con
MIT Mined Bacteria for the Next CRISPR—and Found Hundreds of Potential New Tools
An AI system unearthed a trove of CRISPR-like proteins in minutes instead of weeks or months. CRISPR is a breakthrough technology with humble origins. Scientists first discovered the powerful gene editor in bacteria that were using it as a weapon against invading viruses called phages. Phages can wipe out up to a quarter of a bacterial population in a day. Under assault, bacteria have evolved a hefty arsenal of defenses in a relentless arms race.These bacterial immune systems often chop up the D
