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
Three-way quantum correlations fade exponentially with distance at any temperature, study shows
The properties of a quantum material are driven by links between its electrons known as quantum correlations. A RIKEN ...

Part 1 the Persistent Vault Issue: Your Encryption Strategy Has a Shelf Life
Every enterprise identity platform—from Okta and Azure AD to self-hosted password managers and privileged access management systems—shares a common architectural assumption: credentials are encrypted at rest in persistent storage. AES-256, PBKDF2 stretching, HSM key management—these are table stakes. But they're also irrelevant the moment an attacker exfiltrates your encrypted database.The 2022 LastPass breach exposed the fundamental flaw. Attackers didn't need to defeat encryption in
Show HN: Reverse Turing Test (convince an LLM that you are an LLM)
I often see people throw out the idea that a Turing Test is a way to determine if an AI has general intelligence, but a lot of people don't consider that the situation is symmetrical. It is quite possible to run the test in the opposite direction, with humans trying to trick an LLM into believing that they are also an LLM. If you can't convince an LLM that _you_ are an LLM, are _you_ "generally intelligent?".So I vibe-coded up an app with claude. (I am a developer, but I do
Ask HN: How much of your token use is fixing the bugs Claude Code causes?
My experience using Claude Code is that I will detail work I want it to do, then it does it, then I spend quite a bit of time with it trying to figure out why it didn't work. Putting in debugging sometimes feels like half of the code it is writing. At the same time, I'm using more tokens by default with this "better" version of Claude. Of course I don't think this is 'on purpose' but it feels like there should be some discount on tokens being used to fix the bu
Show HN: VideoZero – 2D Video Generation
Hello Hacker News!
I've been lurking on hacker news, and it is amazing what people have built!I'm Patrick and I built a 2D video generation tool at VideoZero.ai that can produce crisp technical videos (text, formulas, graphs) by using code instead of generating raw pixels.After my PhD, I really wanted to do something more creative, and I started creating educational videos about computer science. I felt there was a huge need for engaging, short educational videos to counter all the let
Show HN: Chiptune Tracker
I built a browser-based tracker app that let's you compose audio across 4 channels. Inspired by the Gameboy audio system - not quite a true recreation but a fun toy nonetheless. Song data is persisted in local storage so you don't lose your progress.<p><a href="https://github.com/daniel-black/chiptune-tracker" rel="nofollow">https://github.com/daniel-black/chiptune-tracker</a>
Ask HN: Was my first management job bad, or is this what management is like?
My first job in management was not good. I became so stressed I got a mild case of shingles[0], and at that point decided to quit for my own health. I didn’t stay long enough to overcome the difficulties—I had to run away.I’m wondering if this job was just especially bad, or if I can expect similar troubles in any management job.It was consulting company work, and I enjoyed it when I was an individual contributor on the team. The company cared about our project in the beginning and things were w
Show HN: Webapps running in Docker containers and earning on token margins
Hello! I hope this is sufficiently different to pique your interest:1) I use Abstract Syntax Trees to have the LLM modify existing code. It will make more targeted changes than I've seen compared to codex/gemini cli/cursor etc. I wrote a blog post about how I do this if you want to know more: https://codeplusequalsai.com/static/blog/prompting_llms_to_m...2) I double-charge for tokens. This creates a margin, so that when you publish your app, you get to ear
Show HN: Hacker Newspaper – Yet another HN front end optimized for mobile
I was trying to find better content (doom) scrolling sources (quit Instagram, YouTube, etc). HN was great but I couldn't read properly on my phone hence I built Hacker Newspaper -- a mobile first HN reader.<p>Key things:
- Mobile-first, newspaper-style UI
- Tap goes to comments, not article
- Nested threads that don't get crushed on small screens<p>Still WIP, would love some feedback. Thanks!
Physicists push quantum boundaries by turning a superfluid into a supersolid — and back — for the first time
Physicists saw excitons, a type of quasiparticle, undergo a reversible phase transition from superfluid to supersolid for the first time, opening new doors for studying extreme states of matter.
Chang’e-6 lunar samples reveal a giant impact reshaped the Moon’s interior
A colossal ancient impact may have reshaped the Moon far more deeply than scientists once realized. By analyzing rare lunar rocks brought back by China’s Chang’e-6 mission from the Moon’s largest crater, researchers found unusual chemical fingerprints pointing to extreme heat and material loss caused by a giant impact. The collision likely stripped away volatile elements, reshaped volcanic activity, and left a lasting chemical signature deep below the surface.
Physicists solve a quantum mystery that stumped scientists for decades
Physicists at Heidelberg University have developed a new theory that finally unites two long-standing and seemingly incompatible views of how exotic particles behave inside quantum matter. In some cases, an impurity moves through a sea of particles and forms a quasiparticle known as a Fermi polaron; in others, an extremely heavy impurity freezes in place and disrupts the entire system, destroying quasiparticles altogether. The new framework shows these are not opposing realities after all, revea
