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

Silicon quantum computer performs logical operations for the first time
Silicon is ubiquitous in modern electronics, and now it is becoming increasingly useful in quantum computing. In particular, silicon's compatibility with existing chip technology and its long coherence times in silicon-based spin qubits make it a promising material for scalable quantum computing. A new study, published in Nature Nanotechnology, has demonstrated silicon's use in a logical quantum processor, representing the first of its kind.
Framework unifies the classical and quantum Mpemba effects
Physicists have developed a new theoretical framework which unifies a wide array of seemingly unrelated "Mpemba effects": counterintuitive cases where systems driven further from equilibrium relax faster than those closer to it. Reporting their results in Physical Review X, researchers led by John Goold at Trinity College Dublin show that both classical and quantum versions of the effect can be understood using the same underlying logic—resolving a long-standing conceptual puzzle.
Webb telescope spots mysterious explosion that defies known physics
Astronomers have spotted a bizarre cosmic explosion that refuses to play by the rules—and it’s leaving scientists scrambling for answers. GRB 250702B, detected by NASA’s James Webb Space Telescope and a global network of observatories, lasted an astonishing seven hours—far longer than typical gamma-ray bursts, which usually fade in under a minute.
Monster black holes are silencing star formation across the universe
A blazing supermassive black hole can influence far more than its own galaxy. Scientists found that quasars emit radiation strong enough to shut down star formation in nearby galaxies millions of light-years away. This could explain why some galaxies near early quasars appear faint or missing. The finding suggests galaxies grow and evolve together, not in isolation.

Lost in space: Microgravity makes sperm lose their sense of direction
Making babies in space may be more complicated than expected, as new research shows sperm struggle to navigate in microgravity. Scientists found that while sperm can still swim normally, they lose their sense of direction without gravity, making it harder to reach and fertilize an egg. In lab experiments simulating space conditions, far fewer sperm successfully made it through a maze designed to mimic the reproductive tract, and fertilization rates in mice dropped by about 30%.

Ask HN: Is consumer AI boxes a viable idea?
I suspect at some point LLM in its current form will be deemed good enough for general research and coding tasks. I don't get why we need to continue with a de-facto cloud-based approach. Cloud in my opinion solves operational complexity, which is worth paying a premium for. But it seems it isn't quite all that complex to get an open source model running locally as long as you have the hardware. Over time I suspect the models get better and cheaper.Is there a future where we can expect
