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

Bitcoin could fall victim to quantum computers sooner than expected. Now crypto investors are turning to these alternative coins

After research from Google suggested a potential threat to some cryptocurrencies, tokens like QRL and Cellframe (CEL) saw their values rise.

A simple explainer on what quantum computing actually is, and why it is terrifying for bitcoin

Most simplifies the complex process of quantum computing as "it can be 0 and 1 at the same time." That is not an explanation for why it threatens Bitcoin. This is.

Wormholes Aren’t Portals After All. But They Do ‘Stitch’ the Whole Universe Together.

Now it seems that wormholes, those shortcut tunnels through time and space that Albert Einstein theorized and that science fiction depicts as portals between two distant galactic points, are at the ...

Show HN: 1B Embeddings

We built a vector search engine based on Quantized Tensor Train (QTT) decomposition. Instead of approximate nearest neighbor (ANN) indices like HNSW or IVF, we factorize the entire dataset into a compressed tensor format and serve exact cosine similarity queries directly from the compressed representation. The headline: 1 billion vectors on a single H100, 38ms query, 100% recall, 66 GB serving.Recall improves with scale at fp16: 96% at 400M → 98% at 500M → 99% at 600M → 100% at 1B. This is the o

Scientists trap light in a layer 1,000x thinner than hair

Researchers have created a nanoscale structure that traps infrared light in a layer just 40 nanometers thick—over 1,000 times thinner than a human hair. By using a unique material with exceptional light-bending properties, they can confine and intensify light far beyond previous limits. This setup also dramatically boosts light conversion effects, turning infrared into visible blue light. The advance could pave the way for smaller, faster photonic technologies.

Mars dust storms are sparking electricity and rewriting the planet’s chemistry

Mars may look like a quiet, dusty world, but it’s actually buzzing with hidden electrical activity. Powerful dust storms and swirling dust devils generate static electricity strong enough to spark faint glowing discharges across the planet, triggering chemical reactions that reshape its surface and atmosphere. Scientists have now shown that these tiny lightning-like events can create a surprising mix of chemicals—including chlorine compounds and carbonates—and even leave behind distinct isotopic

Truckloads of food are being wasted because computers won’t approve them

Modern food systems may look stable on the surface, but they are increasingly dependent on digital systems that can quietly become a major point of failure. Today, food must be “recognized” by databases and automated platforms to be transported, sold, or even released, meaning that if systems go down, food can effectively become unusable—even when it’s physically available.

Scientists built a quantum battery that breaks the rules of charging

Scientists have taken a major step toward futuristic energy tech by building a working prototype of a quantum battery—one that can charge, store, and release energy using the strange rules of quantum physics instead of chemistry. This tiny, laser-powered device hints at a future where energy storage is not only faster but actually improves as systems get larger, flipping the rules of conventional batteries.
