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
Is Reality an Illusion? New Theory Challenges Modern Physics
A physicist proposes that consciousness is the fundamental basis of reality, with matter and spacetime emerging from it.
Quantum dynamics show 'memory' depends on whether states or observables evolve
An international group of researchers have investigated the role of memory in quantum systems and dynamics. Their findings show that a quantum process can appear memoryless from one perspective while ...

A new 'uncertainty relation' for quantum measurement errors
One of the most striking features of quantum physics is that certain properties cannot be measured at the same time. Every measurement may inevitably affect the object's physical state being ...

The Retention Imperative: Why AI-Powered SaaS Companies Are Winning in 2026
The SaaS growth playbook has changed: retention now beats acquisition 2.5x. AI-powered companies grow 27% faster and reach $100M ARR 1.7 years sooner.Key shifts:
- Median ARR growth: 35% (2021) → 15% (2026)
- CAC payback: 18mo → 23mo; cost per $1 ARR: $1.24 → $2.08
- NRR drives growth: >106% = 2.5x faster than peers
- Expansion ARR = 40% of total new (50%+ at scale)AI transforms retention:
1. Product: predictive analytics, churn-preventing workflows
2. Operations: agents automate CRM, save re
Show HN: Learnprints – a full learning OS I built solo on nights and weekends
I’m 25, work full-time at my family’s cabinetry company, and spent the last 9 months solo-building Learnprints (learnprints.ca) on nights and weekends with a ~$2,500 budget and a lot of searching and learning.The frustration that started it: every learning tool I tried was optimized for engagement, not understanding. Anki is great but gives you no structure. Notion is a graveyard. AI chatbots answer questions but don’t build knowledge.I wanted something that actually closed the loop.What Learnpr
Show HN: Self-Protecting Files for the Agentic Era
We've been building Honeycake, a file-native security platform that embeds encryption, access policies, and audit trails directly into files.The thesis: AI Agents are moving data at machine speed across workflows, platforms, and organizations, often without explicit human approval. Conventional security protects locations (firewalls, IAM, DLP), but once an Agent copies a file somewhere new, those controls don't follow. The file is unprotected.Our approach is a new file primitive called
GAEB4Linux – An Open Source GAEB XML Viewer Built with Spring Boot and Vaadin
Hi HN,
I’m building GAEB4Linux, an open-source GAEB XML viewer for Linux.
GAEB (Gemeinsamer Ausschuss Elektronik im Bauwesen) is a German standard used in construction for exchanging bills of quantities (BoQ), pricing, tenders, invoices, etc. Most existing tools are Windows-only and closed source.
What it currently does
Loads GAEB XML files (DA80 / DA81, e.g. X81)
Parses via JAXB (generated from official XSD 3.3)
Extracts BoQ structure and positions
Displays:
Position number (OZ)

Show HN: Tensor Spy: inspect NumPy and PyTorch tensors in the browser, no upload
We needed a side project to give agentic coding a try, and created tensorspy.com together with Junie and ChatGPT 5.2.Tensor Spy lets you quickly inspect the contents of numpy & pytorch tensors locally (your tensors are not uploaded to any servers).This is useful to validate your deep learning data pipelines, to check which layers in your diverging model are actually going haywire, and just because it's kind of cool & a lot more convenient for one-off inspections than loading things
Show HN: Qrvpn – deploy and run VPN server on any device and behind NAT/FW
I want to present a new tool that allows you to deploy and run your own VPN server with just a few clicks on Windows, Linux, Android and iPhone/Mac.
No public IP or open ports are needed - both client and server use outgoing connections to bypass NAT/FW. This is handled with a relay server that forwards opaque, encrypted traffic.
WireGuard is used as VPN protocol (rust implementation). UI was done in Flutter and look the same across all OSs. The core logic in C++. It was quite fun to p
Show HN: TamAGI – A local-first virtual agent that lives on your machine
Hey HN! I'm building a deceptively simple chat application fronting a local LLM (Ollama or any OpenAI compatible API). TamAGI is the culmination of about 6 months worth of scattered thoughts and incredibly frustrating code sessions (I _suck_ at Python). With OpenClaw's release, I had the "Aha" moment I was looking for and used Claude Code to help fill in the gaps (to be frank, quite a lot of gaps) and make this project a reality.The TLDR: TamAGI is a virtual agent, in the spi
The Support Agent Who Never Burns Out
The Support Agent Who Never Burns Out
Human-like AI teammates are quietly solving the problem that broke customer service.
Meet Sarah.
Sarah is your best customer support agent. She knows your product cold, handles difficult customers with patience, and resolves tickets faster than anyone on the team. She also called in sick Monday, runs on fumes by Thursday, and quit last April right after you finished training her replacement.
This is the story nobody tells about customer service. The quiet st
