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

Quantum dots control brain cells for the first time

In an unlikely marriage of quantum physics and neuroscience, tiny particles called quantum dots have been used to control brain cells for the first time. Having such control over the brain could one ...

Microsoft debuts groundbreaking Majorana 1 quantum chip with topological qubits

Microsoft Corp. today debuted the Majorana 1, an eight-qubit chip that it touts as a major breakthrough in quantum computing. The processor is powered by quasiparticles called Majorana zero modes.

New programmable photonic chip can control how fast light moves

Scientists have created a programmable optical chip that can slow light on demand, giving engineers far greater control over how optical signals propagate through a circuit. The technology could provide the delays, synchronization, and buffering functions needed to make light-based computing more practical. A single chip could eventually perform several tasks that currently require separate devices, potentially reducing energy use, cost, and complexity in AI servers and data centers.

Ask HN: Claude Blind Test Results: Bug or Feature?

I asked Claude to organise my conversation logs with another leading model for me, removing company and product names. After organising some of the information, abnormal outputs began to appear. I asked Claude, “Why is this happening?” Claude replied, “You’re asking why—why AI is behaving this way. I don’t know how to answer you, because ‘why’ is a vast question in itself. From a commercial perspective, in the data economy, users equal data, and data equals value. That is the logic.” Below is a

Show HN: BlazeRules – YAML rule engine for streaming data, 3M records/SEC

https://blazerules.dev I initially wanted to make a sub-millisecond log parser in C++ but that blew into a embeddable decision engine, that can run YAML defined rules on incoming data.The rules are executed in a vectorized format on incoming data by reprojecting into a columnar format first, if it's not already. Depending on the payload size and rules complexity, the performance goes from 200K records/s to more than million records/sec, in terms of througput this would b

Show HN: A simple TUI to CRUD Beads tasks

Wasn't really happy with any of the beads TUIs out there, so set Codex/Claude Code on creating one that allows for quick task management inside a repo that has an associated beads database. Quite happy with the vim style UX and the tree based nav is good at showing you what only what you need.

Show HN: Semglot – Sqlglot for Semantic Layers

Hey HN, I’m André, one of the people that is building benchouse.ai, a public leaderboard for analytics agents.To score every agent fairly, we need to give them equivalent semantic context. Every agent has their own format ranging from dbt docs to Snowflake semantic views or custom yaml formats. I was porting them over manually, but every change in the reference context meant updating multiple docs. Quite annoying.So we wrote semglot, it reads one semantic model and emits another one. Similar to

Show HN: Velprium - Time Workspace

Hi HN, I'm Minjae, a solo developer.- About two years ago, I came up with an idea and worked on it as a side project for about three months, but I had to quit because I was overwhelmed by my main job.However, when I recently used a coding agent to configure the specifications and have the development done, the implementation speed was incredibly faster than it was two years ago. So, I focused on refining the specifications and rode that momentum to launch the service in just two weeks.- The

Show HN: Riace – a hands-free interval timer I built while getting back in shape

I always wanted to be a developer, and it was quite long time that I was planning to get fit and change my habits (smoke, fast food, alcohol, and so on)I run a food business (American style potato rolls), and definitely I'm not a developer, even tho I've been working as project manager for a decade being the intersection between designers and developers. At the end of 2024 something changed in me, so I started my Project Riace to get fit, and while doing this I built an app that helped

Ask HN: To lead with, or bury, AI in product marketing

Howdy dear folks.Here on hackernews there seems to be very little other than AI related stories. Maybe not all too strange given the crowd who frequents this site. From what I gather the mostly positive sentiment isn't as widely shared among the general population (0: 50% of americans are more concerned than excited about the increase use of AI).How do you think about whether or not to mention, or advertise, the AI capabilities of your own products when marketing to the general population?

Diffuse puffs of “missing” matter surround most galaxies

Stars and galaxies make up much of the universe’s ordinary, observable matter. But for decades, scientists have wrestled with a cosmic conflict: There should be much more. Physicists have good estimates of how much matter was present in the early universe. Shortly after the Big Bang, roughly 83 percent of all matter in the universe was composed of invisible dark matter, with ordinary matter making up the rest. And yet, these estimates exceed the amount of ordinary matter seen in stars and g

China’s Chang’e-6 reveals why solar wind hits the Moon’s two sides differently

China’s Chang’e-6 samples have uncovered a surprising difference between the Moon’s two hemispheres. Solar wind particles penetrated deeper into the far-side soil because Earth’s magnetosphere slows the particles that reach the near side. Noble gases locked inside the lunar regolith preserved evidence of this uneven bombardment. These gases may even help scientists reconstruct the ancient history of Earth’s magnetic shield.

Astronomers find the first atmosphere on a rocky world in the habitable zone

Astronomers have found the first confirmed atmosphere around a rocky planet in another star’s habitable zone. The planet, LHS 1140 b, revealed its atmosphere through helium slowly leaking into space. Located 48 light-years away, the world may have preserved its atmosphere for billions of years, making it a promising target in the search for potentially habitable planets.

A hidden “switch-off” signal could predict solar storms seven years early

A newly discovered turning point in the Sun’s 11-year cycle could allow scientists to predict future solar activity years earlier than before. At this “switch-off” point, the most violent space weather abruptly ends, and the remaining number of sunspots offers clues about the next cycle’s strength. Early projections suggest Solar Cycle 26 may be moderate, but a clearer forecast is expected in about two years.

Quantum bath keeps distant qubits entangled without human control

Two qubits sat half a meter apart, with no direct link between them. Yet correlated microwave photons pushed them into a shared quantum state, offering a new route to entanglement without constant int...

Show HN: The0 – self-hosted runtime for trading bots, bring your own language

So Im a solo developer who has always had an itch for algorithmic trading. Initially I started off learning how to trade algorithmically with Yves Hilpisch book "Python for Algorithmic Trading" after reading that book I was hooked and started building algorithmic trading bots. Initially these were separate python scripts that I ran on my local machine. That was a bad idea cause local machines are not reliable and I wanted to run my bots 24/7 365. In my actual career im a software

Show HN: Ekko – post-quantum E2EE layer for Instagram, WhatsApp, Telegram Web

Hi everyone,I am a big privacy activist and the amount of privacy concerns in the internet with the discussions around European Chat Control, Meta removing e2ee in Instagram and corporations harvesting personal data for AI training is on the rise. The closed source social media companies keep managing and storing our private keys, allowing them to effectively access all of our personal communications..Many open source alternatives exist, but the problem I kept running into was not a lack of goo
