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

Did an exploding comet wipe out the mammoths?

Scientists are uncovering new clues that a cosmic explosion may have rocked Earth at the end of the last ice age. At major Clovis-era sites, researchers found shocked quartz—evidence of intense heat and pressure consistent with a comet airburst rather than volcanism or human activity. The event could have sparked massive fires, blocked sunlight, and triggered a rapid return to ice-age conditions. These harsh changes may explain the sudden loss of megafauna and the disappearance of the Clovis cul

Scientists spot quantum behavior inside a living system for the 1st time

Quantum effects are no longer confined to ultra-cold chips and vacuum chambers. For the first time, researchers have ...

Russia’s 72-qubit quantum test hits 94% accuracy on 2-qubit ops

Russia has quietly vaulted into the front rank of quantum powers with a neutral-atom machine that combines a 72-qubit scale ...

This tiny chemistry change makes flow batteries last far longer

A new advance in bromine-based flow batteries could remove one of the biggest obstacles to long-lasting, affordable energy storage. Scientists developed a way to chemically capture corrosive bromine during battery operation, keeping its concentration extremely low while boosting energy density through a two-electron reaction. This approach sharply reduces damage to battery components and allows the use of cheaper materials.

A planet just vanished. NASA’s Hubble reveals a violent cosmic secret

Astronomers tracking a nearby star system thought they had spotted an exoplanet reflecting light from its star. Then it vanished. Even stranger, another bright object appeared nearby. After studying years of Hubble Space Telescope data, scientists realized they were not seeing planets at all, but the glowing debris left behind by two massive collisions between asteroid-sized bodies.

Kids With Spinal Muscular Atrophy Show Dramatic Improvement With FDA-Approved Gene Therapy

Once only available for children under two, a one-and-done treatment is now approved for older kids too. Waking up, hopping out of the bed, and stumbling to the kitchen for a cup of coffee: It’s an everyday routine most people don’t think twice about.But for children with spinal muscular atrophy, simply propping themselves up in bed is an everyday struggle. The inherited disease is caused by mutations in the SMN1 gene. Without a working copy of the gene, motor neurons—cells that control muscles—

NASA’s Webb telescope just discovered one of the weirdest planets ever

A newly discovered exoplanet is rewriting the rules of what planets can be. Orbiting a city-sized neutron star, this Jupiter-mass world has a bizarre carbon-rich atmosphere filled with soot clouds and possibly diamonds at its core. Its extreme gravity stretches it into a lemon shape, and it completes a full orbit in under eight hours. Scientists are stunned — no known theory explains how such a planet could exist.

Axion One OS

The AXION One OS architecture represents the convergence of software engineering and cognitive science. By rigorously defining the mechanisms of Global Workspace Synchronization, Internal Reality Awareness, and Consciousness Metrics, we move beyond the "Black Box" of current AI. We are proposing a transparent, measurable, and self-regulating "Glass Box"—a machine that knows it is a machine, understands its world, and seeks to optimize its existence within it. This is not just

Debugging for Systems Programming Learning

Learning systems programming was always an aspiration for me. Understanding more about what the machine was doing when you coded something one way as opposed to another. I always felt a vast gulf between toy examples and real programs. I could grasp the concepts quite well, but did not have a good feel for how to compose them. And when I read code for large systems, it was in the how the developer can composed the pieces that I would begin to feel lost and get discouraged. But that feeling that

Want to Learn about Timepieces

www.thenakedwatchmaker.com I came up with the idea of this website in 2016 after my now ex, quit his job. "what are we going to do now?" he asked. Now divorced, I kept the site. I have been sick with an autoimmune sickness and it's been hard to keep it going. But I'm still standing. I'm now trying to include more diverse elements to the site. Please check it out.

Ask HN: How do people validate deep self-study in math or CS?

I recently decided I wanted to better understand modern cryptography and zero-knowledge proofs. Although I took mathematics courses in college, that was years ago, so I began working through an undergraduate abstract algebra textbook on my own, reading and solving problems most evenings.I made progress, but found it difficult to stay motivated without a clear external benchmark. I kept wishing there were a standardized, rigorous abstract algebra examination I could register for in advance. Somet
