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
AI-Designed Antibodies Are Racing Toward Clinical Trials
“Generative biology is moving drug discovery from a process of chance to one of design.” Antibodies touch nearly every corner of healthcare. These carefully crafted proteins can target cancer cells, control autoimmune diseases, fight infections, and destroy the toxic proteins that drive neurological disorders. They’re also notoriously difficult to make.Over 160 antibody therapies have been approved globally. Their market value is expected to reach $445 billion in the next five years. But the tra
Ask HN: Quantum Computation, Computers and Programming
What are some good resources viz. books/papers/articles/videos/etc. to study about the three domains listed above (from Basics to Advanced)?1) Quantum Computation: What exactly are the abstract models of computation here? Are the Classical Computation models i.e. https://en.wikipedia.org/wiki/Model_of_computation applicable? What other new models have been invented?2) Quantum Computers: What is the Physics, Organization and Architecture of these? In classi
Quantum-dot device can generate multiple frequency-entangled photons
Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path to more powerful quantum communication and computing technologies.
'Nu' citation index may bridge gap between productivity and impact metrics
Researchers propose a new citation index that balances productivity and impact in academic publishing. The h-index of citations was introduced in 2005 by physicist Jorge E. Hirsch. This index is defined simply as the maximum number h of an author's published papers with at least h citations each. For example, h = 3 means that there are three papers with 3 or more citations, but if a fourth paper exists, it has fewer than four citations.
Scientists realize a three-qubit quantum register in a silicon photonic chip
Quantum technologies are highly promising devices that process, transfer or store information leveraging quantum mechanical effects. Instead of relying on bits, like classical computers, quantum devices rely on entangled qubits, units of information that can also exist in multiple states (0 and 1) at once.
This AI spots dangerous blood cells doctors often miss
A generative AI system can now analyze blood cells with greater accuracy and confidence than human experts, detecting subtle signs of diseases like leukemia. It not only spots rare abnormalities but also recognizes its own uncertainty, making it a powerful support tool for clinicians.
Spacecraft capture the Sun building a massive superstorm
Scientists have pulled back the curtain on one of the most extreme solar regions seen in decades, tracking it almost nonstop for three months as it unleashed powerful space weather. By combining views from two spacecraft—one near Earth and one orbiting the Sun—researchers followed a massive active region as it grew, twisted, and ultimately triggered the strongest geomagnetic storms since 2003.
This strange form of water may power giant planets’ magnetic fields
At extreme pressures and temperatures, water becomes superionic — a solid that behaves partly like a liquid and conducts electricity. This unusual form is believed to shape the magnetic fields of Uranus and Neptune and may be the most common type of water in the solar system. New high-precision experiments show its atomic structure is far messier than expected, combining multiple crystal patterns instead of one clean arrangement. The finding reshapes models of icy planets both near and far.
Sci-Fi Cloaking Technology Takes a Step Closer to Reality With Synthetic Skin Like an Octopus
The skin could allow machines to dynamically blend into their surroundings or be used to create adaptive displays and artwork. An octopus’s adaptive camouflage has long inspired materials scientists looking to come up with new cloaking technologies. Now researchers have created a synthetic “skin” that independently shifts its surface patterns and colors like these intelligent invertebrates.The ability to alter an object’s appearance on demand has a host of applications, from allowing

Ask HN: Are LLM providers making LLMs worse on purpose?
The question is less about the classic MoE/Quantization debate, but more about the trained behaviors for a model.<p>It feels like the most ideal model for an LLM provider is the one where user have to follow up with another prompt to clarify or improve the result and make it behave like this maybe 50% of the time to avoid excessive churn.
