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

Decision Models vs. ML Classification

About 13 years ago I made https://jeena.net/catdog using machine learning algorithms to classify pictures of faces of dogs and cats and decide if we’re looking at a cat or a dog. I was in university and this was what I came up with doi...

Show HN: Google Trends for Hacker News Comments

I've seen a fair few posts recently that try to categorise HN posts, so I thought google trends for hacker news would be fun.- chart the popularity of phrases up to 3 words long - includes all hn comments, apart from stuff like who's hiring...

Show HN: I made an app to let skiers track ski resorts and slopes they have done

Hi HN,Ever since I started skiing 2 years ago, I've been completely obsessed with skiing and all aspects of going on a ski trip (the scenery, the food, the thrill of skiing, the community).I was looking at the different ski tracking apps out the...

“110-year calculation in 19 seconds”: How will IBM’s quantum computer change the future?

A meteor hit Oklahoma 100 million years later than scientists thought

A meteor crater buried beneath Oklahoma has turned out to be nearly 100 million years younger than scientists thought. Zircon crystals show the Ames impact occurred about 370 million years ago, meaning it was not part of the mysterious Ordovician bom...

Scientists find a surprising clue to why the universe’s expansion doesn’t add up

Tiny magnetic fields created shortly after the Big Bang may help explain the long-running disagreement over how fast the universe is expanding. Detailed simulations show that these primordial fields could have changed the formation of hydrogen in the...

Scientists just found a new way to make hydrogen from water

A new light-activated material can efficiently produce hydrogen from water without requiring an additional expensive metal catalyst. Researchers say its unusual sulfur-based chemistry could point toward cheaper and more practical ways to turn sunligh...

Show HN: Terminal Gym – a Claude mod that makes you do pushups between prompts

Hi HN, I built this for myself and wanted to open-source it.The problem: I wanted a way to get reminders in-between prompts as I often spend long hours in the terminal, especially now that we're usually parallel-processing so many agents.The fir...

Show HN: Thoreau BASIC – What if BASIC hadn't gone out of fashion?

Thoreau BASIC started as a joke. I wanted a BASIC where I could type something ridiculous like: DIM A%(12000000000) …and have it actually work. Then I kept adding things. The result is Thoreau BASIC, a free x64 BASIC interpreter inspired by GW-BASI...

Reading hidden topology in light, even when energy leaks away

When I explain topology to students, I start with a knot in a rope. You can stretch it, twist it or shake it, but the knot stays until you cut the rope. Physicists have found that some materials and devices carry similar "knots" in how waves move th...
