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

Bill Gates’ warning, first-ever AI brain surgery is successful, and India commits Rs 730 cr for mega quantum-AI campus — Weekly AI Wrap (Aug 24–29)

Meanwhile, memory manufacturers began warning that AI’s appetite for custom silicon might cause global shortages until the ...

Why the Information You Are Waiting for May Not Exist Yet?

Nowadays, especially among the more intelligent of us, a tendency to procrastinate has become increasingly common. A tendency with a specific shape and form, something different than “I just end up doing different things than what I’m expected”, “I c...

This strange “spacetime crystal” can suddenly become a black hole

Physicists have mathematically captured a bizarre “spacetime crystal” that can either dissolve or collapse into a microscopic black hole after only a tiny change in energy. Their breakthrough came from an unusual trick involving infinitely many dimen...

Ask HN: Which repos have merged PRs worth reading?

I read merged PRs on GitHub in the morning instead of the news or doomscrolling. Not the discussion, just the code diff to get inspiration for my own projects and pick up new methods. Also to keep myself close to real code and not only talking to an...

Show HN: Train 300M/32-Layer Model in 1.5GB RAM on Base M1 Mac

Hello again! Since my last post about Ullis, the project has gone through several changes as I was searching for the right architecture. As it turned out, KAN and Hyena were quite resource-heavy, and I couldn't get anything viable out of them. T...

IBM quantum computer solves classically intractable problem in 15 minutes

IBM and University of Chicago researchers have completed a quantum computation that leading classical methods could not practically reproduce. The system used 70 error-corrected logical qubits and finished the task in roughly 15 minutes while also pr...

Hollow-core fiber platform could help different quantum technologies connect

Quantum technologies promise secure communication networks, powerful forms of computing and new sensing tools. One of the major challenges, however, is that different quantum systems often operate at different wavelengths of light. Quantum memories,...

Scientists discover a massive heat anomaly deep inside Mars

Mars has a hidden temperature divide, with its southern interior potentially hundreds of degrees hotter than the north and partially molten. The discovery could help explain several long-standing Martian mysteries, including unusual magnetism, seismi...

A new recipe unlocks “impossible” nanocrystals for LEDs, implants, and superconductors

Scientists have cracked a long-standing chemistry problem, creating nanocrystals from tough metal nitrides that were previously extremely difficult to produce at this scale. The breakthrough could turn familiar materials used in LEDs, implants, and s...

QuEra Computing Uses AI to Automate a Critical Quantum Computer Subsystem, Enabling the Acceleration of Commercial-Grade Quantum Computing Deployments from QuEra

An AI agent, Anthropic's Claude, developed and validated the control logic for the laser system in a QuEra quantum computer, recovering it in seconds versus an expert needing minutes, and holding it ...

Quantum Simulators Put a 40-Year-Old Physics Theory to the Test

For roughly 40 years, physicists have used conformal field theories to predict the precise ratios separating these energy ...

Scientists turn one of the hardest plastics to recycle into high-performance engine lubricant

Researchers have discovered a way to turn notoriously difficult-to-recycle PVC plastic into a key ingredient used in high-performance lubricants such as engine oil. The technique could give mountains of plastic waste a valuable second life while maki...

The universe is still speeding up, but nobody knows why

A major new analysis challenges recent claims that the universe's expansion is slowing, finding that the evidence for cosmic acceleration remains strong. The findings preserve the leading role of dark energy, while leaving scientists with the endurin...
