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
Scientists discover hidden math secret inside Chinese money plant leaves
Scientists have uncovered a hidden mathematical secret inside the leaves of the Chinese money plant: a naturally occurring geometric pattern known as a Voronoi diagram, something typically associated with city planning, computer science, and network design. By mapping tiny pores and looping veins in the plant’s leaves, researchers discovered that the plant organizes itself using the same kind of elegant spatial logic humans use to solve complex distance problems — without ever “measuring” anythi

Deadly “red sky” solar storm from 800 years ago discovered in ancient trees
Researchers in Japan traced a hidden medieval solar storm using ancient tree rings and centuries-old sky observations. The team linked reports of eerie red auroras with spikes of carbon-14 trapped in buried wood, revealing a powerful solar radiation event around 1200 CE. The findings suggest the Sun was far more active at the time, with unusually short solar cycles.
Earth is flying through ancient supernova debris and scientists found the evidence in Antarctic ice
Earth is quietly collecting radioactive debris from an ancient stellar explosion as our Solar System drifts through a giant cloud of gas and dust between the stars. Scientists analyzing Antarctic ice up to 80,000 years old discovered traces of iron-60 — a rare isotope forged in supernova explosions — and found evidence that this “cosmic ash” has been lingering inside the Local Interstellar Cloud for ages. The discovery suggests the cloud surrounding our Solar System was shaped by a long-ago expl
In quantum gravity, the cosmological constant may behave similar to the quantum Hall effect
Trying to solve quantum gravity is frustrating. We have made tremendous progress in quantum theory, but it seems that every time we find a new quantum technique, there's a reason it doesn't quite work with gravity. Take, for example, the case of quantum fluctuations and renormalization.
No more NYT cooperation: my dog-rape red line
Over the years, I’ve written two op-eds for The New York Times about quantum computing, at the NYT editors’ invitation:Quantum Computing Promises New Insights, Not Supermachines (2011)Why Google’s Quantum Supremacy Milestone Matters (2019)I’ve also visited the NYT office and helped NYT reporters with numerous stories about quantum computing and beyond. In the wake of Cade Metz’s hatchet job against the rationalist community, I resolved no longer to talk to Metz, bu

Quantum geometry provides theoretical limits on measurable properties of solids
Two RIKEN physicists have established new theoretical limits for experimentally measurable quantities by viewing solids through a lens of quantum geometry. Their results shed light both on the physics of solids and on quantum mechanics.
Show HN: SLayer, a semantic layer maintained by your agent
Hello HN!If you want to connect your agent to a database (say, to build a data analyst chatbot or any kind of agentic app) today you have 2 options: an SQL MCP server or a semantic layer.SQL MCP is the easiest path to setup, especially if you also have a .md knowledge base which the agent can update. It gets quite messy quickly though, especially if there's many interactions or DB is large. Generated SQL is hard to review if you want to understand where the numbers came from, and related qu
Show HN: NodeDB – High Perfomance Multi-Model Database
Hey HN,I've been working on a multi-model database called NodeDB.Originally, i've found out the idea of SurrealDB quite good. However, it doesn't have some graph and vector features that I need. And since it is just a KV wrapper, instead of purpose-built engine, the performance will never be close to the specialized databases (like Neo4j, Pinecone, Clickhouse, etc).And i've asked myself, what if, there is a database that have the same idea, but built differently? Instead of j
