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

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

The missing dataset for clean-topology 3D mesh generation?

We need a Blender bpy.ops dataset for autoregressive modeling and mesh generation is a dead end being eaten alive by publish or perish.Everyone knows neural mesh generation is a bit of a useless toy, but in 2022, Autodesk Research published SkexGen (ICML 2022), an autoregressive model that generates CAD construction sequences. You sketch a 2D profile, extrude it, boolean it, and each step is a valid CAD operation. SCAD and Adam and whatnot are already extrapolating that to LLMs, and it's fi

Novel protocol reconstructs quantum states in large-scale experiments up to 96 qubits

Quantum computers, systems that process information leveraging quantum mechanical effects, could outperform classical computers on some computationally demanding tasks. Despite their potential, as the size of quantum computers increases, reliably describing and measuring the states driving their functioning becomes increasingly difficult.

A universal scheme can verify any quantum state

Quantum technologies, devices that can process, store, or detect information leveraging quantum mechanical effects, could outperform classical devices in some tasks or scenarios. Despite their potential, verifying that these devices work correctly and truly realize desired quantum states can be challenging, particularly when they cannot be fully examined or inspected.

This hidden state of water could explain why life exists

Scientists have finally found a hidden “critical point” in supercooled water that explains why it behaves so strangely. At this point, two different liquid forms of water merge, triggering powerful fluctuations that affect water even at normal temperatures. The breakthrough was made possible by ultra-fast X-ray lasers that captured water before it froze. This discovery could reshape our understanding of water’s role in nature—and possibly even life itself.

This quantum computing breakthrough may not be what it seemed

A team of physicists set out to test some of the most exciting claims in quantum computing—and found a very different story. Instead of confirming breakthroughs, their careful replication studies revealed that signals once hailed as major advances could actually be explained in simpler ways. Despite the importance of these findings, their work initially struggled to get published, highlighting a deeper issue in science.

Quadratic gravity theory reshapes quantum view of Big Bang

Waterloo scientists have developed a new way to understand how the universe began, and it could change what we know about the Big Bang and the earliest moments of cosmic history. Their work suggests that the universe's rapid early expansion could have arisen naturally from a deeper, more complete theory of quantum gravity. The paper, "Ultraviolet completion of the Big Bang in quadratic gravity," appears in Physical Review Letters.
