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 theory, biological organization, and the mind-brain problem
The relationship between physical theory and biological organization remains one of the most challenging in contemporary science. Part of the inspiration of ...
You Can Expand Your Consciousness to See Hidden Layers of Reality, Oxford Physicist Claims
A leading physicist argues the brain may operate like a quantum system—and that enhancing it could create humans who perceive hidden layers of reality.

IBM Promises 750 Full-Time Jobs At South Side Quantum Campus, Officials Say
The company agreed to create the jobs in exchange for an estimated $19 million in state tax credits to build a computing hub on the planned quantum campus. It also pledged to hire graduates of a new City Colleges program.
The First 5 Quantum Computing Stocks I'd Buy If I Were Starting From Scratch
Both IonQ (NYSE: IONQ) and D-Wave Quantum (NYSE: QBTS) are popular quantum computing investments. They are pure plays, so ...
Breakthrough technique could mean light-powered quantum computers are more viable
Scientists have achieved a breakthrough by "distilling" light to eliminate the noise that prevents photonic quantum computers ...
1,000 Qubits Here We Come: Quantum Art’s Series A Is Now $140 Million
Quantum Art says its 1000-qubit quantum computer isn't that far off. The company just added $40 million to a $100-million ...
IBM files for new quantum computing facility in Poughkeepsie, New York
IBM is planning another building at its quantum campus in Poughkeepsie, New York. As reported by local publication Midhudson ...
IBM announces new innovation center at Chicago quantum park, creating 750 new tech jobs
Building on its growing Chicago quantum footprint, IBM is creating a FutureNow delivery center at the Illinois Quantum and Microelectronics Park, with a commitment to create 750 new full-time technology jobs on the city’s South Side.
IBM CEO makes bold call on quantum computing
IBM CEO Arvind Krishna is doubling down on quantum as IBM’s next big bet. In an April 17 interview with Semafor, Krishna said the technology may not be far off. “Quantum is probably 3 to 5 years away in terms of timing,” he said, adding it “is going to solve the kinds of problems AI could not do.” ...
Show HN: Quldra – A true device based post quantum messenger
Quldra is a messaging app built with post-quantum cryptography from the ground up. Private keys never leave your device. No phone number required. Just secure, private communication designed to stay that way -- even as computing power advances.
Ask HN: What are you doing during inference?
I’ve not seen any good discussion on this, and friends have very varied answers. If you’re using agents to program, what are you doing while they work? Feels like there’s an upper limit to how much work I can supervise and still do a good job (even with the help of supervisor and code-review agents), so I find I’m sat quite a bit not wanting to lose context or context switch too heavily.How are you handling this? Are you sucking it up and running 5 agents so there’s always something requiring yo
Show HN: Pcons: new software build tool in Python, inspired by SCons and CMake
I've been really gratified to see a bit of uptake of pcons in the open-source community, so I thought I'd post an update since it's up to v0.14.1 now. Pcons is a new open-source build tool that's the best of SCons and CMake with fewer of their problems.Since v0.7 (last HN post), there's now a porting guide, LaTeX toolchain, full C++20 module support, Fortran toolchain (including MODULE/USE), WebAssembly via WASI and EMSDK. It can generate pkg-config files, finds MSV
Show HN: AgentPort – Open-source Security Gateway For Agents
Hey HN!I've been wanting to use something like OpenClaw for a while but couldn't get myself to give it access to anything important due to all the risks involved. Prompt injection is still a problem (even though some people seem to ignore it) and so are hallucinations and mishaps that cause agents to do things like delete production data [1].Even harnesses like Claude Code and Codex are subject to this, particularly since we're getting progressively looser about how we run them e.
Show HN: Despatch – Project management for systems thinking, not just software
I've been experimenting with a project management tool for disciplines that use systems thinking, so government services, infrastructure, energy, (non-software) engineering. Things that Jira, Asana, Monday etc. weren't quite designed forThese fields have deep hierarchy (programmes → projects → work packages → tasks), and need first-class data structures for requirements, stakeholders, interfaces, and risk registers — not just tickets and sprints.Existing mainstream tools either force y
Increase in Claude Code speed bumps?
Claude Code seems like it's pausing a lot more than it has previously to ask me kind of frivolous questions about the prompt I've just given it. It seems to be pausing multiple times per step. I've been using CC for quite awhile and have never noticed it until this week in particular.<p>Am I missing a new setting or something? (I do not and will not use the destructive flag(s))
This AI knew the answers but didn’t understand the questions
For decades, psychologists have debated whether the human mind can be explained by one unified theory or must be broken into separate parts like memory and attention. A recent AI model called Centaur seemed to offer a breakthrough, claiming it could mimic human thinking across 160 different cognitive tasks. But new research is challenging that bold claim, suggesting the model isn’t truly “thinking” at all—it’s just memorizing patterns.
A photon was teleported across 270 meters in stunning quantum breakthrough
Scientists have pulled off a first: teleporting a photon’s state between two separate quantum dots. This was done over a 270-meter open-air link, proving quantum information can travel between independent devices. The achievement marks a key step toward building quantum networks for ultra-secure communication. It also sets the stage for more advanced systems like quantum relays.
