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: Cifer, zero-key custody using threshold cryptography

I built CIFER, a distributed encryption + access-control system designed so that no component ever holds a complete decryption key at rest.Core idea: each “secret” (per user or per dataset) has its own independent post-quantum keypair. There is no master key.Architecture summary:Control plane: verifiable ownership, delegation, revocation, and append-only audit records (tamper-evident authorization history)Custody plane: 5 custody nodes running in TEEs, each storing 1 key fragmentOrchestration: v

Rydberg atoms detect clear signals from a handheld radio

For the first time, a team of US researchers has used sensors containing highly excited Rydberg atoms to detect signals from an ordinary handheld radio. Through a careful approach to demodulating the incoming signals, Noah Schlossberger and colleagues at the National Institute of Standards and Technology (NIST) were able to recover audio encoded in multiple public radio channels, with promising implications for everyday uses in consumer electronics. The research has been published in Physical Re

Researchers unlock hidden dimensions inside a single photon

Researchers have discovered new ways to shape quantum light, creating high-dimensional states that can carry much more information per photon. Using advanced tools like on-chip photonics and ultrafast light structuring, they’re pushing quantum communication and imaging into exciting new territory. Although long-distance transmission remains tricky, innovative approaches—such as topological quantum states—could make these fragile signals far more resilient. The momentum suggests quantum optics is

Apollo rocks reveal the Moon had brief bursts of super-strong magnetism

Scientists at the University of Oxford have finally settled a decades-long mystery about the Moon’s magnetic field — and it turns out both sides were right. By reanalyzing Apollo mission rocks, they discovered that the Moon did occasionally generate an incredibly powerful magnetic field, even stronger than Earth’s — but only for fleeting bursts lasting thousands of years or less. Most of the time, the Moon’s magnetic field was weak.

Energy loss triggers quantum thermal Hall-like effect at macroscopic scale

In many quantum materials—materials with unusual electrical and magnetic properties driven by quantum mechanical effects—electrons can organize themselves into Landau levels. Landau levels are essentially quantized energy states that form when charged particles move in a magnetic field.

Show HN: I got tired of writing Pandas scripts just to JOIN two CSV files

Every few weeks I get 2-3 CSV files and need to run a quick JOIN or aggregation. The options are always the same: fire up pandas, import into SQLite by hand, or use some janky web tool.So I built a plugin for Tabularis (my native DB GUI) that treats a folder of CSV files as a database. Drop your files in, every file becomes a table, column types are inferred automatically, and you get a full SQL editor.No code. No imports. Just SQL.Example: 3 CSV files (users, orders, products) → this query work

Show HN: ZSE – Open-source LLM inference engine with 3.9s cold starts

I've been building ZSE (Z Server Engine) for the past few weeks — an open-source LLM inference engine focused on two things nobody has fully solved together: memory efficiency and fast cold starts.The problem I was trying to solve: Running a 32B model normally requires ~64 GB VRAM. Most developers don't have that. And even when quantization helps with memory, cold starts with bitsandbytes NF4 take 2+ minutes on first load and 45–120 seconds on warm restarts — which kills serverless and

Show HN: Cosmos-Reason2-2B on Nano Super

Hi! Today, me and my team is releasing a version of Cosmos-Reason2-2B that is quantized so that it fits even on the NVIDIA Jetson Orin Nano Super.<p>We managed to find a mixed precision configuration such that it maintains virtually the same accuracy as the unquantized model while being able to run really efficiently on the Nano Super and other edge devices :)

Ask HN: How do you think about financial runway before quitting?

I have been thinking about changing jobs.What surprised me is that I was not afraid of the change itself. I was unsure how long I could realistically sustain myself if my income dropped.Most tools I found were full budgeting systems or complex financial software. I did not need tracking. I needed clarity about how many months my current situation could hold under different scenarios.How do you approach this?Do you run detailed spreadsheets? Do you assume a conservative burn rate? Do you factor i

Ask HN: How to exhaustively search the scientific literature?

I have a need for a comprehensive database of a certain type of event described in the scientific literature. For what it&#x27;s worth, the event is a &#x27;paleoearthquake&#x27;, which is a historic or prehistoric earthquake that is found in the geologic record, usually by digging a trench across a fault line and identifying the disturbances in the geologic strata across or adjacent to the fault and, if possible, dating them via radiocarbon or other geochronological methods. However I don&#x27;

Tell HN: Planning to end my life today

Tell HN: Going to end my life todayI&#x27;m 35 and I am going to end my life today. About year one ago I quit my job to work on my own startup (alone). Since then I made good progress in making the product, but very little in selling it. And there&#x27;s competition in that space with newly-funded VC startups out-executing me. Shit I was so scared to contact my ICP to prospect and to sell -- I am ashamed at myself for messing this opportunity. I WASTED 10 MONTHS!!!! Also realized: it is an uphil

Terms of use: What types of competition do model providers ban?

I thought it would be interesting to look at the terms of service of the frontier labs and there was more deviation than I expected when it comes to the issue of building competing offerings. Note that I am not a lawyer and none of this is legal advice. You should refer to the specific versions of the agreements that apply to you and consult with a lawyer.It is very common for technology companies (particularly when providing data through an API,) to include a term that more-or-less says their c

Show HN: A Simple Obisidan plugin to draw ASCII shapes like MS Paint

I like to draw things ascii on obsidian when I am working on projects but sometimes it&#x27;s quite challanging for me because the line starts to shift as I edit some regions. I ended up building a ms paint like canvas experience for ascii so instead of thinking like it&#x27;s text, we think like it&#x27;s canvas but it still draws texts. Also, it supports embed on other notes and dynamic canvas size for your preference.

Ask HN: Should you include a list of technologies in your CV?

I&#x27;m talking about a &quot;skills&quot; section where you simply list the technologies you have experience with, presumably tailored a bit for the role you are applying for. Like this:Skills: - Java - AWS - Kafka - RabbitMQ - Docker ...Do recruiters care at all about such a list?If I&#x27;d be recruiting, I&#x27;d be only interested in what specific achievements the candidate has, regardless of what programming language or cloud provider they have used. But I&#x27;ve noticed that this list s

What are the best coping mechanisms for AI Fatalism?

Your kids forwarded you Matt Shumer&#x27;s Something Big Happened article. Your feed exploded with the Citrini 2028 Global Intelligence Crisis and its artful, immutable chain reactions. The key leaders of the AI labs struggle openly with the morality of what they are building as their safety leaders quit in frustration. Policy leaders strive to regulate AI as if it were atomic weapons (thanks Oppenheimer).What are the best psychological coping mechanism for this stage of the S-curve?Asking for a

Show HN: Kinetic SQL – A lightweight, real-time SQL Engine for Node.js

Hi HN, I&#x27;m the author.I&#x27;ve spent years building Node.js backends (mostly Express and NestJS) and I’ve consistently found traditional ORMs like TypeORM too heavy, while Prisma’s subscription models didn&#x27;t quite fit my need for lightweight CDC (Change Data Capture). I wanted something universal that felt closer to the metal but still handled real-time events seamlessly.Over the past couple of days, I built Kinetic SQL. It&#x27;s a thin, highly flexible SQL wrapper for Node.js (suppo
