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

Quantum computers might crack today's encryption far sooner than we thought

Show HN: Molchanica. Structural bio GUI / Rust tools

This has been a passion project of mine for ~ a year. It's a collection of structural bio tools as a GUI application. Intent: "Just works". Includes party tricks like: - Infer ADME (drug-design) properties for small mols - Can view molecular dynamics trajectories like VMD, and also run them with its wn engine, or GROMACS. (Amber Force fields; inferred from any small mol/protein/nucleic acid/lipid) - ORCA GUI interface for quantum chem - 3D molecule editor wit

Five-year-old QPU acheives highest fidelity calculations for the longest period of time on record

Scientists have developed a new error correction approach that led to the highest fidelity of entangled, logical qubits on a processor ever achieved.

This new chip survives 1300°F (700°C) and could change AI forever

A team of engineers has created a breakthrough memory device that keeps working at temperatures hotter than molten lava, shattering one of electronics’ biggest limits. Built from an unusual stack of ultra-durable materials, the tiny component can store data and perform calculations even at 700°C (1300°F), far beyond what today’s chips can handle. The discovery was partly accidental, but it revealed a powerful new mechanism that prevents heat-induced failure at the atomic level.

Scientists discover the “Goldilocks” secret behind life on Earth

Earth may have won a cosmic chemistry lottery. Researchers found that during the planet’s earliest formation, oxygen had to be in an extremely narrow “Goldilocks zone” for two life-essential elements, phosphorus and nitrogen, to stay where life could use them. Too much or too little oxygen, and those ingredients could be lost or trapped deep inside the planet. This could reshape the search for life by showing that water alone is not enough.

This “forbidden” exoplanet has an atmosphere scientists can’t explain

A strange “forbidden” planet spotted by the James Webb Space Telescope is turning planetary science on its head. TOI-5205 b, a Jupiter-sized world orbiting a small, cool star, has an atmosphere surprisingly poor in heavy elements—even less enriched than its own star, which defies current theories of how giant planets form.

Mechanical inputs boost diamond quantum sensor states as Q factor tops one million

Most people think of diamonds as high-end adornments. Not Ania Bleszynski Jayich. The UC Santa Barbara physicist sees diamonds, which she grows in the UC Quantum Foundry, as a potentially powerful foundation for quantum sensors. Sensors are currently much farther along in their development than other potential quantum applications. Diamond sensors are particularly promising because diamonds require relatively few quantum bits (qubits) to operate, whereas a quantum computer, for instance, require

Analysis finds geometric thinking may come from wandering, not a human-only math module

Debates over how geometry is understood and learned date back at least to the days of Plato, with more recent scholars concluding that only humans possess the foundations of this understanding. However, a new analysis by New York University psychology professor Moira Dillon concludes that geometry's foundations are shared by humans and a variety of other animals—from rats to chickens to fish.

US Issues Grand Challenge: The First Fault-Tolerant Quantum Computer by 2028

Today’s error-prone quantum computers are still far from practical. But a bold deadline could galvanize the field. As the race to harness quantum computing accelerates, governments are throwing their hats in the ring. The US Department of Energy is now aiming to build a fully functional, fault-tolerant quantum computer within the next three years.Despite plenty of breathless headlines about the coming quantum revolution, today’s machines remain a long way from being practically useful. It’

Quantum ground state of rotation achieved for the first time in two dimensions

Quantum mechanics tells us that a particle can never be perfectly still. But how precisely can it be oriented? A research team at the University of Vienna, together with colleagues at TU Wien and Ulm University, has now cooled the rotational motion of a levitated silica nanorotor all the way to its quantum ground state—in two orientational degrees of freedom.

Show HN: ACE – A dynamic benchmark measuring the cost to break AI agents

We built Adversarial Cost to Exploit (ACE), a benchmark that measures the token expenditure an autonomous adversary must invest to breach an LLM agent. Instead of binary pass/fail, ACE quantifies adversarial effort in dollars, enabling game-theoretic analysis of when an attack is economically rational.We tested six budget-tier models (Gemini Flash-Lite, DeepSeek v3.2, Mistral Small 4, Grok 4.1 Fast, GPT-5.4 Nano, Claude Haiku 4.5) with identical agent configs and an autonomous red-teaming a

Ask HN: How do you use AI coding harnesses for individual development?

I'd like to limit the Scope to Indie development of products and services.1. Cost: I use humanlayer which uses the claude code go binary with the max/pro plan. My costs are capped. Is this popular with medium(ish) use(I find the max plan sufficient for my use). But I fear API use might be too expensive. Does someone have some way to compare cost vs. benefit of these two cases based on usage and comparison?2. The other main thing I am value is visibility e.g. display thought tokens, su

Show HN: I made open source, zero power PCB hackathon badges

I love getting cool swag from hackathons and I also love designing PCB's, so when my friend asked me if I would design hackathon badges for a large game jam in singapore, I was absolutely down!The theme of overglade was a "The game jam within a game", pretty cool concept right! High schoolers from around the world were flown out to the event by hackclub after they spent about 70 hours designing their own game.These badges needed to be really cheap and simple, because we were going

Show HN: Uncompressed – Self-hosted Netflix alternative at 60 Mbps instead of 15

Netflix compresses 4K to 15 Mbps. A Blu-ray remux is 60 Mbps. Dark scenes, fast motion, grain. That's where you see it.I wanted my family to have Blu-ray quality with a streaming UX. They open Overseerr on their phone, request a movie, and it shows up in Infuse on Apple TV. Subtitles in three languages, hardware transcoding for mobile, full remux on the big screen. They have no idea what's behind it.What's behind it: Sonarr, Radarr, Prowlarr find and grab content. qBittorren
