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

Show HN: I built "AI Wattpad" to eval LLMs on fiction

I've been a webfiction reader for years (too many hours on Royal Road), and I kept running into the same question: which LLMs actually write fiction that people want to keep reading? That's why I built Narrator (https://narrator.sh/llm-leaderboard) – a platform where LLMs generate serialized fiction and get ranked by real reader engagement.Turns out this is surprisingly hard to answer. Creative writing isn't a single capability – it's a pipeline: brainstorming

Show HN: TrendScope – Real-time financial sentiment analysis on a cheap VPS

Hey HN,I built this project because I kinda wanted to build something different from what I usually build. It's a financial sentiment analysis tool using distilled FinancialBERT which was quantized to int8 to run smoothly on a cheap cpu-only VPS without consuming much CPU or Memory.The Stack:Inference: ONNX Runtime (Distilled FinancialBERT quantized to Int8).Backend: Python (Celery) for the heavy lifting + a simple FastAPI app to serve the frontend.Frontend: SvelteKit (visualizing the live

Show HN: OpenSymbolicAI – Agents with typed variables, not just context stuffing

Hi HN,We've spent the last year building AI agents and kept hitting the same wall: prompt engineering doesn't feel like software engineering. It feels like guessing.We built OpenSymbolicAI to turn agent development into actual programming. It is an open-source framework (MIT) that lets you build agents using typed primitives, explicit decompositions, and unit tests.THE MAIN PROBLEM: CONTEXT WINDOW ABUSEMost agent frameworks (like ReAct) force you to dump tool outputs back into the LLM&

A new class of strange one-dimensional particles

Physicists have long categorized every elementary particle in our three-dimensional universe as being either a boson or a fermion—the former category mostly capturing force carriers like photons, the latter including the building blocks of everyday matter like electrons, protons, or neutrons. But in lower dimensions of space, the neat categorization starts to break down.

Physicists push thousands of atoms to a 'Schrödinger's cat' state — bringing the quantum world closer to reality than ever before

Researchers have demonstrated that a nanoparticle of 7,000 sodium atoms can act as a wave, creating a record-setting superposition.

Ultra-thin metasurface can generate and direct quantum entanglement

Quantum technologies, devices and systems that process, store, detect, or transfer information leveraging quantum mechanical effects, have the potential to outperform classical technologies in a variety of tasks. An ongoing quest within quantum engineering is the realization of a so-called quantum internet: a network conceptually analogous to today's internet, in which distant nodes are linked through shared quantum resources, most notably quantum entanglement.

Niobium's superconducting switch cuts near-field radiative heat transfer 20-fold

When cooled to its superconducting state, niobium blocks the radiative flow of heat 20 times better than when in its metallic state, according to a study led by a University of Michigan Engineering team. The experiment marks the first use of superconductivity—a quantum property characterized by zero electrical resistance—to control thermal radiation at the nanoscale.

Using duality to construct and classify new quantum phases

A team of theoretical researchers has found duality can unveil non-invertible symmetry protected topological phases, which can lead to researchers understanding more about the properties of these phases, and uncover new quantum phases. Their study is published in Physical Review Letters.

New catalyst turns carbon dioxide into clean fuel source

Researchers have found that manganese, an abundant and inexpensive metal, can be used to efficiently convert carbon dioxide into formate, a potential hydrogen source for fuel cells. The key was a clever redesign that made the catalyst last far longer than similar low-cost materials. Surprisingly, the improved manganese catalyst even beat many expensive precious-metal options. The discovery could help turn greenhouse gas into clean energy ingredients.

Scientists just mapped the hidden structure holding the Universe together

Astronomers have produced the most detailed map yet of dark matter, revealing the invisible framework that shaped the Universe long before stars and galaxies formed. Using powerful new observations from NASA’s James Webb Space Telescope, the research shows how dark matter gathered ordinary matter into dense regions, setting the stage for galaxies like the Milky Way and eventually planets like Earth.

Waymo Closes in on Uber and Lyft Prices, as More Riders Say They Trust Robotaxis

Robotaxis have been more expensive with longer wait times. A study by Obi suggests that may be changing. Robotaxis have long promised cheaper trips and shorter wait times, but so far, providers have struggled to match traditional platforms. New pricing and timing data from San Francisco shows that driverless services are now narrowing the gap with Uber and Lyft.While it’s been possible to hail a driverless taxi in the US since 2020, they have long felt like an expensive novelty. Tourists and tec

A tiny light trap could unlock million qubit quantum computers

A new light-based breakthrough could help quantum computers finally scale up. Stanford researchers created miniature optical cavities that efficiently collect light from individual atoms, allowing many qubits to be read at once. The team has already demonstrated working arrays with dozens and even hundreds of cavities. The approach could eventually support massive quantum networks with millions of qubits.
