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

NEC spent decades developing quantum hardware, but it's time to leave

NEC's quantum computing retreat leaves Fujitsu gaining experienced researchers while the Japanese giant shifts toward ...

Which Bitcoin Wallets Are at Risk From Quantum Computers? 6.9 Million BTC Have Exposed Keys

About 6.9 million Bitcoin have public keys visible on-chain. One check on your own address decides whether your coins are ...

Show HN: Objo Studio. A modern visual RAD IDE for desktop and web

I posted Objo Studio here some months ago when it was much earlier in development and it didn’t get much attention. Since then it has changed quite a bit, so I thought it was worth showing again.Objo Studio is my attempt to build a modern version of...

1,000 times faster operations bring reliable quantum computing a step closer

So far, quantum computers have been held back by their extreme sensitivity to errors and external disturbances. The longer a ...

Scientists made gravity act on an atom in a quantum superposition — the surprising result could bring Einstein’s theory and quantum physics closer together

Physicists have directly linked quantum mechanics and Einstein's gravity theory. An experiment used ultracold atoms in ...

Physicists turn classical light into a quantum machine for information processing

Quantum computers promise to tackle problems that are extraordinarily difficult for today's computers. But there is a major ...

Dwarf Star Support for DeepSeek 4.1 Flash on MBPro 128GB

Antirez just landed a commit[1] to the github repo for DwarfStar that adds support for his heavily quantized variant of DeepSeek V4.1 Flash.He claims it runs with SSD streaming on a macbook pro M5-Max 128 GB laptop. The code was just checked in liter...

FutureWhy So Many AI Researchers Think the Machines Could Kill EveryoneWill Knight | Wired ($)“Genuinely stunning advances in AI capabilities—an OpenAI model solved a centuries-old math problem in a matter of hours—have come amid a rash of secu...

Tiny sound waves could help solve a major quantum computing problem

Researchers at Harvard have demonstrated a way to protect quantum information using microscopic sound waves. By continuously surrounding a diamond-based qubit with mechanical vibrations, they extended its coherence time by roughly threefold. The same...

Physicists turn classical light into a quantum machine for information processing

Quantum computers promise to tackle problems that are extraordinarily difficult for today's computers. But there is a major obstacle: quantum systems are notoriously fragile. Noise, loss and even tiny disturbances can destroy the delicate behavior th...

Researchers find a Wordle strategy that wins 99% of the time

Researchers at Binghamton University have developed a mathematical strategy that can solve Wordle with a 99% success rate. Instead of simply guessing words packed with common letters or choosing the most likely answer, the method uses Shannon entropy...

Show HN: A Modern C++ course with videos and interactive GitHub homeworks

Hi HN. Over the last couple of years in my free time, I’ve been designing and recording a complete modern C++ course. I wanted to share it here in case people still care about things like this in this brave new age of AI.The course is absolutely fr...

Show HN: Table – A fast, streaming-first table renderer for Go

I built this because I wanted one Go table library that could handle text, HTML, GFM, CSV/TSV, and other table-oriented output without giving up streaming.The main design goal is to provide both a Table API and a row-at-a-time Stream API for eve...

Ask HN: Did Google kill its enterprise workhorse model?

Is anyone else in a panic over the Gemini 2.5 model generation (Pro, Flash) being sunset in October before there's even any Pro class model in general availability (with geo restrictions etc.)? Google wants everyone to migrate to 3.x Flash, wh...
