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

MIT Mined Bacteria for the Next CRISPR—and Found Hundreds of Potential New Tools

An AI system unearthed a trove of CRISPR-like proteins in minutes instead of weeks or months. CRISPR is a breakthrough technology with humble origins. Scientists first discovered the powerful gene editor in bacteria that were using it as a weapon against invading viruses called phages. Phages can wipe out up to a quarter of a bacterial population in a day. Under assault, bacteria have evolved a hefty arsenal of defenses in a relentless arms race.These bacterial immune systems often chop up the D

'Voorhees law' explains why the slower car often catches up

Many drivers will know the feeling: you pull ahead of the slower car you've been stuck behind and cruise the open road ahead at your own, faster speed. By the time you reach the next stop light, you're sure that you've left the slower car far behind you—but to your surprise, you see that same car cruise up right behind you in the mirror. Horror buffs might even recall scenes from "Friday the 13th," where masked villain Jason Voorhees always catches up to his sprinting victims—despite himself wal

Quantum computing without interruptions

Mid-circuit measurements are one of the biggest practical hurdles in quantum error correction on encoded qubits. Researchers in Innsbruck and Aachen have now proposed and experimentally demonstrated that a universal fault-tolerant quantum algorithm can be executed without such measurements. Using a trapped-ion quantum processor, the team successfully ran Grover's quantum search algorithm on three logical qubits.

Before we start on quantum

Imagine that every week for twenty years, people message you asking you to comment on the latest wolf sighting, and every week you have to tell them: I haven’t seen a wolf, I haven’t heard a wolf, I believe wolves exist but I don’t yet see evidence of them anywhere near our town.Then one evening, you hear a howl in the distance, and sure enough, on a hill overlooking the town is the clear silhouette of a large wolf. So you point to it — and all the same people laugh and accuse you of “crying wol

Show HN: Molchanica. Structural bio GUI / Rust tools

This has been a passion project of mine for ~ a year. It's a collection of structural bio tools as a GUI application. Intent: "Just works". Includes party tricks like: - Infer ADME (drug-design) properties for small mols - Can view molecular dynamics trajectories like VMD, and also run them with its wn engine, or GROMACS. (Amber Force fields; inferred from any small mol/protein/nucleic acid/lipid) - ORCA GUI interface for quantum chem - 3D molecule editor wit

This new chip survives 1300°F (700°C) and could change AI forever

A team of engineers has created a breakthrough memory device that keeps working at temperatures hotter than molten lava, shattering one of electronics’ biggest limits. Built from an unusual stack of ultra-durable materials, the tiny component can store data and perform calculations even at 700°C (1300°F), far beyond what today’s chips can handle. The discovery was partly accidental, but it revealed a powerful new mechanism that prevents heat-induced failure at the atomic level.

Scientists discover the “Goldilocks” secret behind life on Earth

Earth may have won a cosmic chemistry lottery. Researchers found that during the planet’s earliest formation, oxygen had to be in an extremely narrow “Goldilocks zone” for two life-essential elements, phosphorus and nitrogen, to stay where life could use them. Too much or too little oxygen, and those ingredients could be lost or trapped deep inside the planet. This could reshape the search for life by showing that water alone is not enough.

This “forbidden” exoplanet has an atmosphere scientists can’t explain

A strange “forbidden” planet spotted by the James Webb Space Telescope is turning planetary science on its head. TOI-5205 b, a Jupiter-sized world orbiting a small, cool star, has an atmosphere surprisingly poor in heavy elements—even less enriched than its own star, which defies current theories of how giant planets form.

Mechanical inputs boost diamond quantum sensor states as Q factor tops one million

Most people think of diamonds as high-end adornments. Not Ania Bleszynski Jayich. The UC Santa Barbara physicist sees diamonds, which she grows in the UC Quantum Foundry, as a potentially powerful foundation for quantum sensors. Sensors are currently much farther along in their development than other potential quantum applications. Diamond sensors are particularly promising because diamonds require relatively few quantum bits (qubits) to operate, whereas a quantum computer, for instance, require

Analysis finds geometric thinking may come from wandering, not a human-only math module

Debates over how geometry is understood and learned date back at least to the days of Plato, with more recent scholars concluding that only humans possess the foundations of this understanding. However, a new analysis by New York University psychology professor Moira Dillon concludes that geometry's foundations are shared by humans and a variety of other animals—from rats to chickens to fish.

US Issues Grand Challenge: The First Fault-Tolerant Quantum Computer by 2028

Today’s error-prone quantum computers are still far from practical. But a bold deadline could galvanize the field. As the race to harness quantum computing accelerates, governments are throwing their hats in the ring. The US Department of Energy is now aiming to build a fully functional, fault-tolerant quantum computer within the next three years.Despite plenty of breathless headlines about the coming quantum revolution, today’s machines remain a long way from being practically useful. It’

Quantum ground state of rotation achieved for the first time in two dimensions

Quantum mechanics tells us that a particle can never be perfectly still. But how precisely can it be oriented? A research team at the University of Vienna, together with colleagues at TU Wien and Ulm University, has now cooled the rotational motion of a levitated silica nanorotor all the way to its quantum ground state—in two orientational degrees of freedom.

Show HN: ACE – A dynamic benchmark measuring the cost to break AI agents

We built Adversarial Cost to Exploit (ACE), a benchmark that measures the token expenditure an autonomous adversary must invest to breach an LLM agent. Instead of binary pass/fail, ACE quantifies adversarial effort in dollars, enabling game-theoretic analysis of when an attack is economically rational.We tested six budget-tier models (Gemini Flash-Lite, DeepSeek v3.2, Mistral Small 4, Grok 4.1 Fast, GPT-5.4 Nano, Claude Haiku 4.5) with identical agent configs and an autonomous red-teaming a
