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
Graduate Student Proves a Quantum Uncertainty Principle for Fractals
At the quantum scale, tiny particles behave in bizarre ways. One reason for this is the uncertainty principle, which says that the more you know about where a quantum particle is, the less you can know about how fast it’s moving, and vice versa. Recently, this rule got a rare upgrade. The new uncertainty principle relates to fractals, shapes that remain equally complex no matter how much you…Source
Scientists turn Starlink into a giant scanner for Earth’s upper atmosphere
Researchers have found a clever new way to map a part of Earth’s upper atmosphere that is notoriously difficult to observe. Using orbital data from roughly 1,200 Starlink satellites, they reconstructed changes in atmospheric density about 500 kilometers above Earth. The approach could sharpen satellite tracking and help reduce the growing risk of collisions in increasingly crowded orbits.

A 20-year-old quantum entanglement theory has finally been confirmed in experiments
(Tony Melov/Canva) Quantum mechanics is so odd that even the visionary genius who described the secrets of the Universe seemed to dismiss certain aspects as eerie. "Spooky action at a distance" is how ...
Ask HN: How do you handle uncertain GPU capacity needs months in advance?
If your product has variable or spiky compute requirements, how do you secure capacity when you know you may need a large GPU block in a few weeks or months, but are uncertain about the timing or quantity?The apparent choices are to reserve capacity in advance and risk underutilizing it, or wait and accept price and availability risk in the on-demand market. I’m curious how inference providers, enterprises running fine-tunes or evals, and teams with batch or seasonal workloads handle this in pra
Show HN: Needle2: 14MB agentic LLM for phones, wearables, smart home and robots
Hey HN,Henry from Cactus here!We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2.The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits betw
Show HN: ReadAware – an extensible eBook reader that evolves with you
I enjoy reading books, and I wanted an ebook reader that could give me some help while I read, instead of making me wander around between different apps and lose my attention.Also, I never really found an existing ebook reader that fits my taste. To be honest they feel kind of clunky to me, and their AI integrations are usually pretty primitive or just feel like a chatbot added on the side. That's why I started ReadAware.So what makes it stand out?First, it's an agent-first reader. But
Ask HN: iMessage Agents?
it seems quite obvious that imessage is the best venue for consumer agents<p>why was poke not a success?
Show HN: SecondState – what if Hebbia started with raw ERP data?
Hi HN,I have been tinkering on a project for quite some time now.
Most AI finance tools begin after the data is ready. Financial Diligence and audits don’t.I built SecondState to start one layer earlier.The interesting pieces:- Agentic data transformation: It has kind of cursor for “data engineers” : you declare what you want and the agent builds the DAG and materialize it with a human-in-the-loop approval gate.- Just-in-time Analytics: once you have some clean data, you can ask whatever questio
Show HN: The Rotten Tomatoes for AI films, ranked by the tools that made them
I wanted a rotten tomatoes for ai film, hence popcorn.movie, because AI films need a critical and technical review that's different to movies, and we're in the 1895-1920's of ai movies right now.Many festivals, people, industries, sites reject or suppress ai, for many great reasons (slop), and of course slopscrolling and other sites have the slop problem, as does this - the idea is to look past the slop to the real stories and technically great content, with an view that ai is a t
Show HN: An open-source video editor built for coding agents
Hey HN! We’ve been working on this project for almost 3 years now, and recently decided to finally make it open source.It’s a local-first video editor that runs in the browser and is mostly built from scratch. We’re using WebCodecs for all the encoding and decoding work, which lets us get performance pretty close to native editors.Since day one the goal of the project was to solve LLM-based video editing, but the models have only recently become capable enough to make it genuinely useful. Instea
Show HN: I wrote the emudev hello world (CHIP-8 emulator in C)
Yep, just another CHIP-8 emulator. But for me, as someone who has never written anything this low level and never touched C before, it was quite the challenge at first. But after writing the first few instructions (drawing especially), it slowly became almost a breeze. Until I had to debug why my font sprites were rendering all messed up.It's still work in progress, definitely not finished, but today I have tried to run some official CHIP-8 ROMs instead of just tests and my super simple tes
Launch HN: Discovered Materials (YC P26) – AI agents to discover new materials
Hey HN, we're Advaith and Akash from Discovered Materials ( https://discoveredmaterials.com/ ). We build AI agents that discover new materials for the semiconductor industry.GPUs today have a heat problem. Nvidia & AMD are almost doubling the TDP (Thermal Design Power) in every chip they release - the H100 (released 2022) has a TDP of 700W, Blackwell (2024) gives out 1.2 kW and Rubin (2026) gives out at 2.3 kW of heat. This trend is expected to continue, and getting rid
Quantum advantage reassessed: More realistic benchmarks for quantum algorithms
Quantum advantage refers to the point at which a quantum computer solves a clearly defined task faster or more efficiently than any classical computer—or makes it solvable in the first place. For many practical applications, this has not yet been demonstrated. Research therefore relies heavily on theoretical models and simulations to explore where and under what conditions such an advantage may realistically be achieved in the future.
Long-sought Zhang-Rice singlet visualized directly in cuprate superconductor
Superconductors are materials that conduct electricity with zero electrical resistance below specific temperatures. Most of these materials become superconducting at very low temperatures, but some also exhibit superconductivity at higher temperatures.
