Researchers have used atoms trapped by light to sustain quantum superposition. The cat is both dead and alive.

Imagine how a phone call works: Your voice is converted into electronic signals, shifted up to higher frequencies, transmitted over long distances, and then shifted back down so it can be heard clearly on the other end. The process enabling this shifting of signal frequencies is called frequency mixing, and it is essential for communication technologies like radio and Wi-Fi. Frequency mixers are vital components in…

A new algorithm solves complicated partial differential equations on triangle meshes by breaking them down into simpler problems, potentially guiding complex modeling and analysis in computer graphics and geometry processing.

Turbulence is ubiquitous in nature. It exists everywhere, from our daily lives to the distant universe, while being labeled as "the last great unsolved problem of classical physics" by Richard Feynman. Prof. Dr. Huirong Yan and her group from the Institute of Physics and Astronomy at the University of Potsdam and DESY have now discovered a long-predicted phenomenon: the weak-to-strong transition in small amplitude…

Recent advancements in hyperspectral imaging and machine learning have revolutionized the non-destructive monitoring of crop nutritional status, enabling accurate prediction of plant element concentrations. Despite successes, the single-target regression method, which predicts concentrations individually, faces accuracy limitations for certain elements.

A protein engineering method using simple, cost-effective experiments and machine learning models can predict which proteins will be effective for a given purpose, according to a new study by University of Michigan researchers.

Gene regulatory networks (GRNs) depict the regulatory mechanisms of genes within cellular systems as a network, offering vital insights for understanding cell processes and molecular interactions that determine cellular phenotypes. Transcriptional regulation, a prevalent type for regulating gene expression, involves the control of target genes (TGs) by transcription factors (TFs).

Researchers created new AI models to simulate how trees grow and shape in response to their environments.

Feng Guo, an associate professor of intelligent systems engineering at the Indiana University Luddy School of Informatics, Computing and Engineering, is addressing the technical limitations of artificial intelligence computing hardware by developing a new hybrid computing system—which has been dubbed "Brainoware"—that combines electronic hardware with human brain organoids.

Each year at its annual meeting, the American Physical Society's Division of Fluid Dynamics sponsors a contest for the best images in a variety of categories, all related to the flow of fluids.

Ultrafast lasers have the advantages of high time resolution, high energy density, broadband spectrum, etc. Ultrafast lasers with high-energy and high peak power have been widely applied in industrial fields and frontier science, such as advanced manufacturing, photomedicine, and ultrafast physics.

Mirage largely returns to the stealth-based gameplay of past titles, while adding a new insta-kill Focus system, fun combat tools, and a bustling Middle East-city setting.Ubisoft's historical fiction epic, Assassin's Creed, has seen a slew of themes, premises, and gameplay concepts across its [...]

Professor Wei Xiong's group, from the Wuhan National Laboratory for Optoelectronics at Huazhong University of Science and Technology, proposes a pioneering high-speed multi-photon polymerization lithography technique with a record-high 3D printing rate of 7.6 × 107 voxel s−1, which is nearly one order of magnitude higher than earlier scanning multiphoton lithography (MPL).

MIT system demonstrates greater than 100-fold improvement in energy efficiency and a 25-fold improvement in compute density compared with current systems. ChatGPT has made headlines around the world with its ability to write essays, email, and computer code based on a few prompts from a user. Now

Updated: We take a deep dive into the inner workings of the wildly popular AI chatbot, ChatGPT. If you want to know how its generative AI magic happens, read on.

MIT's "Lightning" system connects photons to the electronic components of computers using a novel abstraction, creating the first photonic computing prototype to serve real-time machine-learning inference requests.
