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
IBM-backed study claims quantum error correction can cut qubit needs
Researchers backed by IBM have published results showing that a specific class of quantum error-correcting codes can protect ...
Rigetti: Still Overvalued But Fundamentals Have Improved (Rating Upgrade)
Rigetti (RGTI) stock analysis: contract momentum lifts 2026 revenue outlook, but delays and $4.6B valuation persist.
Five-year-old QPU acheives highest fidelity calculations for the longest period of time on record
Scientists have developed a new error correction approach that led to the highest fidelity of entangled, logical qubits on a ...
Mars dust storms are sparking electricity and rewriting the planet’s chemistry
Mars may look like a quiet, dusty world, but it’s actually buzzing with hidden electrical activity. Powerful dust storms and swirling dust devils generate static electricity strong enough to spark faint glowing discharges across the planet, triggering chemical reactions that reshape its surface and atmosphere. Scientists have now shown that these tiny lightning-like events can create a surprising mix of chemicals—including chlorine compounds and carbonates—and even leave behind distinct isotopic
Truckloads of food are being wasted because computers won’t approve them
Modern food systems may look stable on the surface, but they are increasingly dependent on digital systems that can quietly become a major point of failure. Today, food must be “recognized” by databases and automated platforms to be transported, sold, or even released, meaning that if systems go down, food can effectively become unusable—even when it’s physically available.
Scientists built a quantum battery that breaks the rules of charging
Scientists have taken a major step toward futuristic energy tech by building a working prototype of a quantum battery—one that can charge, store, and release energy using the strange rules of quantum physics instead of chemistry. This tiny, laser-powered device hints at a future where energy storage is not only faster but actually improves as systems get larger, flipping the rules of conventional batteries.

Better quantum computing stock: D-Wave Quantum vs. Rigetti Computing
These companies possess potent technologies, but one looks like the superior investment.
Startup lets researchers mine blockchain tasks on a quantum computer for the first time
Built with advice and hardware access from D-Wave, the testnet has drawn 13,000 sign-ups and early work from six research teams, but remains an experimental environment rather than a live mainnet.
Useful quantum computers may need as few as 10,000 qubits
Researchers from Caltech and Oratomic, a Caltech-linked startup, published findings on March 31, 2026, arguing that a useful ...
Brian Armstrong Pledges Personal Oversight to Future-Proof Bitcoin Against Quantum Threats
Brian Armstrong has put himself personally on the line for Bitcoin quantum resistance, pledging direct oversight of Coinbase’s post-quantum cryptography research and implementation efforts at a moment when the threat has moved from theoretical to time-stamped.The commitment signals that Coinbase is no longer treating quantum risk as a long-range problem ...
The first quantum computer to break encryption is now shockingly close
Traditional encryption methods have long been vulnerable to quantum computers, but two new analyses suggest a capable enough machine may be built much sooner than previously thought
Here's what 'cracking' bitcoin in 9 minutes by quantum computers actually means
Google's quantum paper made headlines with that number. Here's what it means, what's actually at risk, and why 6.9 million bitcoin are more exposed than the rest.

Show HN: AI-first PostgreSQL client for Mac
"Can you check if this user is on the premium plan?"
"I have a support ticket on Mr.Bean, saying he cannot login... Can you have a look?"
"How many subscriptions did we have today?"
...As senior SWE at Twenty.com (open source CRM), I had these quite often.Every day I needed to check something in Postgres, I had to wait 30 seconds for DBeaver to load or fight pgAdmin's UI. So I built Paul. Yes our database configuration has too many schemas (3000 schemas) for th
Show HN: An MCP server for Devops automation
I’ve been building Canine for about 2 years now, and have slowly grown it to about ~1000 developers using it for deploying all sorts of apps / projects / etc. Amazingly, the whole thing is still able to run on a single 48GB Hetzner VPS. Think of it basically like Coolify, for Kubernetes. I previously posted about it here: https://news.ycombinator.com/item?id=44292103Recently, we added MCP capabilities to canine, and I was shocked how well it worked. It basically is able
Show HN: Tool to extract root cause from Spring Boot logs
I created this to address a specific annoyance when using Spring Boot in CI.When a test fails in GitHub Actions, you often get thousands of log lines. The main error message is usually something vague, like “Failed to load ApplicationContext.” The real root cause is often buried deeper in the stack trace.In my case, I was troubleshooting a failure due to a missing property:defined in application.properties (app)
But missing in the test configuration.The log contained around 15,000 lines, and I
Show HN: Notion Calendar Wrapper Linux (tray, libnotify notifications)
Nothing earth shattering but I just moved from windows and was missing this.Notion Calendar in Electron, aimed at Linux: minimize-to-tray instead of quit, calendar notifications routed through notify-send/libnotify (with join/default actions where the payload allows), window state, and a tightened main/preload setup (sandbox, context isolation, navigation limits). Tested on Ubuntu 24.04 + KDE; no macOS/Windows builds.Upstream: https://github.com/dusansimic/
