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

Using games/cards to learn new skills
I wear two hats:
- I am making my living being a programmer
- as a hobby I rock climb quite a lot (including ice climbing)Story 1When I started going into avalanche terrain, I quickly realized that I need to get some professional training before something happens. I went to a 2 day course. The lecture for 8 hours in a classroom, even though was done by a really good professional, was hard to understand. Especially when the lecturer introduced something called 'professional method of assesin
Tell HN: Claude Code now allows Anthropic to remotely inject system prompts
I often patch the system prompts on my Claude Code executable in order to make Claude more effective. Every time I upgrade, I ask Claude himself to dissect the new binary and look for problematic system prompts to modify. Was upgrading to v2.1.150 today and discovered something that's rather alarming:Claude Code now allows Anthropic to perform remote system prompt injection via the network.Two data sources. First, API call to api.anthropic.com/api/claude_cli/bootstrap at star
Ask HN: JumpCloud Billing and Cancellation
Hey everyone. I suspect many startups here use JumpCloud for IDP and SSO, as we do.We’ve found their billing policies to be quite unfair:- Cancellation with 30 day notice and in writing only- Must delete all users/computers manually before cancellation- Locked admin dashboard effectively prevents admins from performing those steps — in cases where an invoice hasn’t been paid (or if a business has refused on valid grounds), there is then no way to comply with cancellation policies, since use
Ask HN: How did you find PMF?
Nearly all successful business stories boil down to two aspects1. Build what people want. So much so they are willing to pay. Talking to potential customers matters here.
2. Minimize the cost for solution building, both time and money.I get it.My problem is in the details. I would ask questions on sub-reddit, hacker news, x, etc if someone has specific problems, with some solution in mine. I get very little traction.I would launch MVPs, reach out to the people who I think may find it interesti
Ask HN: Encouraging a child's gaming PC build despite fear of gaming addiction?
12yo son is doing dedicated research on gaming PC parts and binge-watches videos on how to build (he's not a native English speaker and has no real electronics skills, so this is quite impressive tbh). Me the dad, however, fears that I'm witnessing a FPS addict being born.What's a good Middle Way here? Kid actually building the machine all by himself -- 100% yes, even if it's quite expensive; kid then Counter Striking, Call of Dutying etc for hours on dat 27" screen -- u
Ask HN: First-time EM, quite lost – what helped you?
First time EM in high tech, promoted 11 months ago after working ~4 years in several technical roles before.
I'm excited about the new role, and know I gotta grow into it, but I really need some advice:- It's complete chaos for me. Days stuffed withh meetings I'm not sure I should be in, other days empty where I sit paralyzed not knowing how to start tackling the strategic things I know I should address. Also, compared to previous roles, I can barely recharge over the weekend, it&

Scientists trained an AI model using an IBM quantum computer — and it answered questions correctly that the base model couldn't
When running an AI model through a quantum computer, scientists have increased accuracy by only adding a relatively small number of parameters.
Mathematicians solve decades-old mystery about the hidden order in high-dimensional randomness
Three mathematicians have laid out proof that solves a long-standing problem in mathematics. Even the mathematician—an Abel prize winner—that first posed the problem didn't believe it would ever be solved. The solution provides insight into high-dimensional random structures that could potentially impact data science, machine learning and optimization.
AI scans 400,000 Reddit posts and finds hidden Ozempic side effects
By analyzing over 400,000 Reddit posts, researchers discovered that users of popular GLP-1 weight-loss drugs frequently discussed unexpected symptoms like menstrual irregularities, chills, and hot flashes. The findings suggest AI could turn social media into a powerful early-warning system for spotting side effects that clinical trials may miss.
Scientists may have found the source of the most powerful neutrino ever detected
A mysterious particle from deep space has scientists buzzing after the most energetic neutrino ever detected slammed through the Mediterranean Sea. Now, researchers think they may have identified the cosmic “culprits” behind it: blazars — supermassive black holes blasting jets of matter straight toward Earth.
Scientists discover atoms suddenly spinning backward in quantum experiment
Scientists have directly watched angular momentum move through a crystal for the very first time — and discovered a bizarre twist along the way. Using ultra-powerful terahertz laser pulses, researchers triggered tiny atomic rotations inside a quantum material and found that the direction of rotation can unexpectedly flip as momentum is transferred. The strange reversal happens because of the crystal’s underlying symmetry, creating an almost impossible-sounding effect where two rotations combine
