Published 2D material reshapes 3D electronics for AI hardware



Researchers demonstrated monolithic 3D integration of layered 2D material into novel processing hardware for artificial intelligence computing. The new approach provides a material-level solution for fully integrating many functions into a single, small electronic chip -- and paves the way for advanced AI computing.
Published Researchers show an old law still holds for quirky quantum materials



Long before researchers discovered the electron and its role in generating electrical current, they knew about electricity and were exploring its potential. One thing they learned early on was that metals were great conductors of both electricity and heat. And in 1853, two scientists showed that those two admirable properties of metals were somehow related: At any given temperature, the ratio of electronic conductivity to thermal conductivity was roughly the same in any metal they tested. This so-called Wiedemann-Franz law has held ever since -- except in quantum materials. Now, a theoretical argument put forth by physicists suggests that the law should, in fact, approximately hold for one type of quantum material, the cuprate superconductors.
Published What was thought of as noise, points to new type of ultrafast magnetic switching



Researchers discover a new type of ultrafast magnetic switching by investigating fluctuations that normally tend to interfere with experiments as noise.
Published How do you make a robot smarter? Program it to know what it doesn't know



Engineers have come up with a new way to teach robots to know when they don't know. The technique involves quantifying the fuzziness of human language and using that measurement to tell robots when to ask for further directions. Telling a robot to pick up a bowl from a table with only one bowl is fairly clear. But telling a robot to pick up a bowl when there are five bowls on the table generates a much higher degree of uncertainty -- and triggers the robot to ask for clarification.
Published Researchers engineer a material that can perform different tasks depending on temperature



Researchers report that they have developed a new composite material designed to change behaviors depending on temperature in order to perform specific tasks. These materials are poised to be part of the next generation of autonomous robotics that will interact with the environment.
Published Nextgen computing: Hard-to-move quasiparticles glide up pyramid edges



A new kind of 'wire' for moving excitons could help enable a new class of devices, perhaps including room temperature quantum computers.
Published Compact accelerator technology achieves major energy milestone



Researchers have demonstrated a compact particle accelerator less than 20 meters long that produces an electron beam with an energy of 10 billion electron volts (10 GeV). There are only two other accelerators currently operating in the U.S. that can reach such high electron energies, but both are approximately 3 kilometers long. This type of accelerator is called a wakefield laser accelerator.
Published Defending your voice against deepfakes



Computer scientists have developed AntiFake, a tool to protect voice recordings from unauthorized speech synthesis.
Published New way of searching for dark matter



Wondering whether whether Dark Matter particles actually are produced inside a jet of standard model particles, led researchers to explore a new detector signature known as semi-visible jets, which scientists never looked at before.
Published New method uses crowdsourced feedback to help train robots



A new technique enables an AI agent to be guided by data crowdsourced asynchronously from nonexpert human users as it learns to complete a task through reinforcement learning. The method trains the robot faster and better than other approaches.
Published 'Strange metal' is strangely quiet in noise experiment



Experiments have provided the first direct evidence that electricity seems to flow through 'strange metals' in an unusual liquid-like form.
Published First experimental evidence of hopfions in crystals opens up new dimension for future technology



Hopfions, magnetic spin structures predicted decades ago, have become a hot and challenging research topic in recent years. New findings open up new fields in experimental physics: identifying other crystals in which hopfions are stable, studying how hopfions interact with electric and spin currents, hopfion dynamics, and more.
Published How we play together



Psychologists are using EEG to research what games reveal about our ability to cooperate.
Published AI can 'lie and BS' like its maker, but still not intelligent like humans



A researcher contends that the understanding of AI is muddled by linguistics: That while indeed intelligent, AI cannot be intelligent in the way that humans are, even though 'it can lie and BS like its maker.'
Published Creativity in the age of generative AI: A new era of creative partnerships



Generative AI (e.g., ChatGPT) has propelled AI into the mainstream, raising concerns about job displacement and creative work. Experts now emphasize a need to focus on 'co-creativity,' the human-AI interaction instead. Extensive research is needed for comprehending co-creativity which is crucial for the future development of AI.
Published AI system self-organizes to develop features of brains of complex organisms



Scientists have shown that placing physical constraints on an artificially-intelligent system -- in much the same way that the human brain has to develop and operate within physical and biological constraints -- allows it to develop features of the brains of complex organisms in order to solve tasks.
Published AI: Researchers develop automatic text recognition for ancient cuneiform tablets



A new artificial intelligence (AI) software is now able to decipher difficult-to-read texts on cuneiform tablets. Instead of photos, the AI system uses 3D models of the tablets, delivering significantly more reliable results than previous methods. This makes it possible to search through the contents of multiple tablets to compare them with each other. It also paves the way for entirely new research questions.
Published Research reveals rare metal could offer revolutionary switch for future quantum devices



Quantum scientists have discovered a rare phenomenon that could hold the key to creating a 'perfect switch' in quantum devices which flips between being an insulator and superconductor.
Published Three-pronged approach discerns qualities of quantum spin liquids



In 1973, physicist Phil Anderson hypothesized that the quantum spin liquid, or QSL, state existed on some triangular lattices, but he lacked the tools to delve deeper. Fifty years later, a team has confirmed the presence of QSL behavior in a new material with this structure, KYbSe2.
Published The mind's eye of a neural network system



A new tool, based on topology, makes finding the areas where neural networks are confused as simple as spotting mountaintops from an airplane. The ability to spot and address those areas of confusion should enable more confident application of neural networks in high-stakes decision scenarios or image prediction tasks like healthcare and research.
