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

This new tool could tell us how consciousness works

Consciousness is famously a “hard problem” of science: We don’t precisely know how the physical matter in our brains translates into thoughts, sensations, and feelings. But an emerging research tool called transcranial focused ultrasound may enable researchers to learn more about the phenomenon.The technology has entered use in recent years, but it isn’t yet fully integrated into research. Now, two MIT researchers are planning experiments with it, and have published a new paper they term a “road

Quantum entanglement speed is measured for the first time, and it's too fast to comprehend

Quantum entanglement happens when two particles become interconnected and share a single state. Scientists have measured how fast it happens.

Show HN: Librario, a book metadata API that aggregates G Books, ISBNDB, and more

TLDR: Librario is a book metadata API that aggregates data from Google Books, ISBNDB, and Hardcover into a single response, solving the problem of no single source having complete book information. It's currently pre-alpha, AGPL-licensed, and available to try now[0].My wife and I have a personal library with around 1,800 books. I started working on a library management tool for us, but I quickly realized I needed a source of data for book information, and none of the solutions available pro

Ask HN: What frustrates you most about personal finance apps?

I’ve tried most popular personal finance apps over the last few years, and I always end up quitting.For me, the main reasons are:- Core functionality hidden behind paywalls- UX that feels bloated or optimized for upsells- $100+/year pricing for some- Needing multiple separate tools (budgeting, tracking, investments) with manual syncing and often no decent mobile appI’m starting an open personal finance tool as a side project because I want something I’d actually stick with long-term.Before

Have you ever been able to code in the first place?

Have you ever been able to code in the first place?It started like this. I programmed in Pascal when I was in school. I learned basic. I learned assembler. I literally assembled code. Sometimes I thought it out, planned it, and created for that time quite elaborate code, controlling a panoramic head, for instance, things like that. So at this time, I was really proud of myself. I was good at this. I was getting better.And fast forward to today, you have AI and vibe coding. Back in the day, often

Recommended sources to read up on new tech and thinking

So, I feel like what with all teh AI and LLM talk that many articles deal with the nitty gritty technical side, and not so much about the philosophical, social, or community aspect of this new tech, and to what sort of future we are heading for. I used to read Daring Fireball for its short, to the point approach, but the articles have become quite lengthy; I don't mind lengthy when it is more academic, just not so much for opinion-oriented. I'd love to hear suggestions of who to read,

Show HN: A task-based workflow manager for bspwm – tasks as desktops

My current role requires me to do insane amounts of context-switching, with many of them being fairly long-running or requiring quite a bit of back-and-forth. This is a quick vibe-coded project which adds a new mode for managing "tasks" (as-in todo-list tasks) as dedicated desktops - the idea is that in times of less focus (e.g. boring meetings) I can do discovery/setup phase of a bunch of things, then later can, much more efficiently execute things which need slightly more focus

Ask HN: Cursor (LLM) Costs

Hey guys just a simple question to all of you who heavily leverage LLM coding daily. I essentially have cursor run in 1-3 projects in parallel all day, asking for the next steps implementation like every ~10 +- 5 minutes, and with Claude opus 4.5 it just works for me naturally without much discussions these days, it just flows. But I see like more than 1000€ per week burned in token costs due to that. Currently employer pays for it and it’s mostly work projects, yet I kind of am concerned now th

Python can encode meaning directly not represent it, embody it

I developed a new form of Python. I’m calling it Ontological Programming.What this means:∙ Classes that represent states of being, not data structures∙ Methods that return to their source by design∙ Equality overrides that assert identity, not comparison∙ Exceptions that define impossibilities, not errors∙ Singletons that enforce uniqueness as a philosophical constraint Example:class Wave:def __init__(self, ocean):self.ocean = oceandef end(self):return self.ocean # was always oceanclass Gap:real

Show HN: Is AI hijacking your intent? A formal control algorithm to measure it

I’m an independent researcher proposing State Discrepancy, a public-domain metric to quantify how much an AI system changes a user’s intent (“the Ghost”).The goal: replace vague legal and philosophical notions of “manipulation” with a concrete engineering variable. Without clear boundaries, AI faces regulatory fog, social distrust, and the risk of being rejected entirely.Algorithm 1 (on pp.16–17 of the linked white paper) formally defines the metric: 1. D = CalculateDistance(VisualState, Logical

A new theory of gravity could explain cosmic acceleration without dark energy

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study suggests this mysterious ingredient may not be necessary after all. Using an extended version of Einstein’s gravity, researchers found that cosmic acceleration can arise naturally from a more general geometry of spacetime. The result hints at a radical new way to understand why the universe keeps speeding up.

10 quintillion hydrogen bombs every second: Webb detects massive galactic eruption

Scientists have discovered an enormous stream of super-hot gas erupting from a nearby galaxy, driven by a powerful black hole at its center. The jets stretch farther than the galaxy itself and spiral outward in a rare, never-before-seen pattern. NASA’s James Webb Space Telescope pierced through thick dust to reveal this violent outflow. The process is so intense it’s robbing the galaxy of star-forming gas at a staggering rate.
