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
Show HN: Runtime AI safety via a continuous "constraint strain" score
Hi HN — I’ve been working on a small open-source experiment around runtime AI safety.The idea is to treat AI risk not as a binary “safe/unsafe” state or post-hoc failure analysis, but as accumulated constraint strain over time — similar to how engineers think about mechanical stress.The project defines a simple, model-agnostic signal (GV) and a lightweight runtime monitor (Sentinel) that classifies risk into bands (green/yellow/red) and suggests interventions (alert, throttle, hum
Show HN: Quantarded, extracting WSB stock signals using OpenAI
I built Quantarded, a side project that turns two noisy public data sources into conservative weekly stock signals.For Reddit (r/wallstreetbets), it uses OpenAI strictly as a semantic parser to extract tickers and buy/sell/neutral intent from text, then applies a mechanical weekly scoring model (recency decay, attention share, buy/sell imbalance). No fundamentals, no price features, no user weighting.For U.S. House trade disclosures, it uses a separate, slower model focused o
Show HN: Duperr – On-device voice cloning using Qwen3-TTS for iOS
I built an iOS app that runs Qwen3-TTS-12Hz-0.6B locally on your phone. No server calls, no data leaves your phone.You can record a voice, generate speech, export audio files, and share custom voices. The model is quantized to 8-bit to run on iPhone. One-time purchase for export/import features when it launches, but generation will remain unlimited when launched. No subscription.Beta: https://testflight.apple.com/join/98d1hB6UHappy to answer any questions!
Qubits: The Building Blocks of Quantum Computing
Qubits, or quantum bits, are the fundamental units of information in quantum computing. Unlike classical bits, which can only exist in one of two states (0 or 1), qubits can exist in multiple states ...

AI that talks to itself learns faster and smarter
AI may learn better when it’s allowed to talk to itself. Researchers showed that internal “mumbling,” combined with short-term memory, helps AI adapt to new tasks, switch goals, and handle complex challenges more easily. This approach boosts learning efficiency while using far less training data. It could pave the way for more flexible, human-like AI systems.
Radio waves revealed what happened before a star exploded
For the first time, astronomers have captured radio signals from a rare exploding star, exposing what happened in the years leading up to its death. The radio waves reveal that the star violently shed huge amounts of material shortly before it exploded, likely due to interaction with a nearby companion star. This discovery gives scientists a new tool to rewind the clock on stellar deaths. It also shows that some supernovae are far more dramatic in their final moments than previously thought.
AI Now Beats the Average Human in Tests of Creativity
A study tested several AI models and 100,000 people. AI was better than average but trailed top performers. Creativity is a trait that AI critics say is likely to remain the preserve of humans for the foreseeable future. But a large-scale study finds that leading generative language models can now exceed the average human performance on linguistic creativity tests.The question of whether machines can be creative has gained new salience in recent years thanks to the rise of AI tools that can gene
Study: The infant universe’s “primordial soup” was actually soupy
In its first moments, the infant universe was a trillion-degree-hot soup of quarks and gluons. These elementary particles zinged around at light speed, creating a “quark-gluon plasma” that lasted for only a few millionths of a second. The primordial goo then quickly cooled, and its individual quarks and gluons fused to form the protons, neutrons, and other fundamental particles that exist today.Physicists at CERN’s Large Hadron Collider in Switzerland are recreating quark-gluon plasma (QGP) to b
Show HN: I built a local macOS dictation app using Nvidia Parakeet and MLX
I built a voice dictation app for macOS mostly because I was tired of how awful Siri is and I didn't want to pay a subscription for cloud tools.The app uses NVIDIA's Parakeet v3 (TDT) as the primary engine. Inference is handled by the FluidAudio library. It's insanely fast on M-series chips. For Intel users, I added local Whisper support ranging from Tiny up to Large v3 Turbo (quantized to save space).The interesting part was the AI integration. I originally tried to pipeline the
Show HN: Quantifying Data Drift Using Coefficient of Variation and Numba
I realized that 'data quality' is often vague, so I wanted to build a deterministic score (0-100) for how stable a dataset is.

Show HN: Chippery, an OpenCode fork that (often) uses 20-40% fewer tokens
I kept hitting token limits with Claude Code on larger codebases and ended up building Chippery (a fork of OpenCode) to reduce context size outside the model.It uses a symbolic index, navigation layer, semantic and Pagerank-like ranking and some context reduction / compression techniques to avoid resending and rereading the same files and lookups.I ran benchmarks mostly with Anthropic’s models, and saw roughly 20–40% token reduction depending on workflow on average, in some cases quite a bi
Show HN: Donkey Support –> Reply to Support Chats from Slack/Discord/Telegram
Hi HNI built Donkey Support, a lightweight support widget for web apps that routes customer chats into Slack, Discord, or Telegram threads, so you can reply from the tools you already use instead of checking another support dashboard.I originally built this because the last early-stage SaaS I worked on was full of bugs. We were moving fast, review wasn’t great, and things broke a lot.What saved us wasn’t perfect code. It was fast support.We had a little support widget on the site, and the second
What's the Point of Clawdbot?
I personally don't get it.I can interact with ChatGPT and Claude directly using apps on my phone.I can already upload pictures and files from my phone to both the above.Before long those apps will be able to access other data sources on my phone directly such as email, Google Drive with better integration.I never need to work with files stored on my Mac mini remotely when I'm out and about. Most of my stuff is in the cloud anyway.We already have Cowork, computer use, addons for Chrome
Ask HN: My boss wants us to vibe code and I feel in danger
I am using a throwaway account because my boss scared the hell out of me.I work for a large AI team (think one of the big ones... Won't say which). And our CEO gave a short but quite clear talk: you HAVE to vibecode. He will check how much we vibe code, how many PRs etc, and will act accordingly.Now. I work in the infra team. What this vibe code mandate means for me is that my work will become unsustainable. I will forecast hordes of PRs impossible to review in time, bloated to the roof. An

Thinking on different wavelengths: New approach to circuit design introduces next-level quantum computing
Quantum computing represents a potential breakthrough technology that could far surpass the technical limitations of modern-day computing systems for some tasks. However, putting together practical, large-scale quantum computers remains challenging, particularly because of the complex and delicate techniques involved.
A sudden signal flare reveals the hidden partner behind fast radio bursts
A repeating fast radio burst has just given up one of its biggest secrets. Long-term observations revealed a rare signal flare caused by plasma likely ejected from a nearby companion star. This shows the burst source isn’t alone, but part of a binary system. The finding strengthens the case that magnetars interacting with stellar companions can generate repeating cosmic flashes.
