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
All Life Uses 20 Amino Acids. Scientists Just Deleted One in Bacteria.
The synthetic bacteria push the limits of life and could open the door to designer proteins and new medicines. The bacteria grew, thrived, and divided for hundreds of generations. But they were unlike any other living creatures on Earth. These synthetic cells, called Ec19, were the first to have had one protein “letter”—or amino acid—partially removed.All life today relies on a set of 20 amino acids to make proteins. Some exotic microbes can use 22, but no one has yet found any that use less. Li
Scientists connect “time crystal” to real device in quantum breakthrough
A strange kind of matter that “ticks” forever without energy input has just taken a major leap toward real-world use. Known as a time crystal, this quantum system repeats its motion endlessly—like a clock that never winds down—and scientists have now managed to connect it to an external device for the first time. By linking the time crystal to a tiny mechanical oscillator, researchers showed they can actually control its behavior, opening the door to powerful new technologies.
Stanford’s new chip boosts light 100x with surprisingly low energy
Researchers at Stanford have developed a compact optical amplifier that dramatically boosts light signals using very little power. By recycling energy inside a looping resonator, the device achieves strong amplification with minimal noise and wide bandwidth. Its efficiency and small size mean it could run on batteries and be integrated into consumer electronics. This breakthrough could enable faster communications and more powerful optical technologies.
This tiny outer Solar System world has an atmosphere. It shouldn’t
Astronomers have spotted something surprising in the far outer Solar System—a faint, short-lived atmosphere clinging to a tiny icy world that shouldn’t be able to hold one at all. The object, called 2002 XV93, is far smaller than Pluto, yet observations during a rare stellar alignment revealed its presence through a subtle dimming of starlight. Even more puzzling, calculations suggest this atmosphere should vanish within about 1,000 years unless it’s constantly being replenished.

Show HN: Quadium 4004 – A visual laboratory for the Intel MCS-4 architecture
I’ve spent a few months building this. It’s basically a visual env for the Intel 4004 because I wanted to see what's actually happening in the buses and registers without 'black boxes'.<p>It has a transpiler called QuadBasic to go from high-level syntaxs to native MCS-4 machine code. Just a personal project from a senior dev to tribute the 1971 pioneers. Happy to answer any tech questions if you find it interesting.
Show HN: Cubitoo Journal, your web journaling app
It was first an iOS app but now it's 100% proud Ruby on Rails web app that works everywhere you can receive your emails. With 18+ guided journaling programs and things that make journaling easy, fun, and interesting.<p>It's an alpha/beta release so please don't hesitate to ask questions and share your feedback — I want to make it the best journaling app :-)
Astronomers pin down the origins of a planetary odd couple
Across the Milky Way galaxy, a planetary odd couple is circling a star some 190 light years from Earth. A normally “lonely” hot Jupiter is sharing space with a mini-Neptune, in a rare and unlikely pairing that’s had astronomers puzzled since the system’s discovery in 2020.Now MIT scientists have caught a glimpse into the atmosphere of the mini-Neptune, which is circling inside the orbit of its Jupiter-sized companion, and discovered clues to explain the origins of this unusual planetary system.I
An AI Just Beat Doctors at Diagnosing ER Patients
AI has aced medical exams, but there’s a wide gap between tests and the real world. A new study suggests the divide is closing. Emergency doctors make high-stakes decisions in fast-paced, often chaotic situations. They have to figure out which patient most urgently needs care, what’s wrong, and what to do next.AI could lend a hand. In a series of challenging scenarios, OpenAI’s o1-preview model matched or exceeded doctors in clinical reasoning. Debuted in 2024, the AI is a large language m
Scientists just created exotic new forms of matter that shouldn’t exist
A new quantum physics study reveals that simply changing a magnetic field over time can unlock entirely new forms of matter that don’t exist under normal conditions. By carefully “driving” materials with timed magnetic shifts, researchers created exotic quantum states that could be far more stable and resistant to errors—one of the biggest challenges in quantum computing. This breakthrough suggests that the future of quantum technology may depend not just on what materials are made of, but how t

SQL access to crypto market data, not just JSON
Hi HN,I’m Nazim, founders of Koinju.io and I wanted to share here an exploratory option we opened very recently: providing access to our database, which contains all cryptocurrency market data, via SQL. REST give access for direct retrieval but we're thinking more and more that SQL access for analytical work over a unified crypto market data layer could be of something because of llms.This was partly triggered by Didier Lopes, ceo of OpenBB recent essay on financial firms owning the infrast
