The topic of electricity often poses difficulties for many secondary school students in physics lessons. Physics Education Researchers at the Goethe University and the University of Tübingen have developed and empirically evaluated a new, intuitive curriculum as part of a major comparative study. The result: not only do secondary school students gain a better conceptual … [Read more...] about New curriculum improves students’ understanding of electric circuits in schools

Oak Ridge National Laboratory researchers have developed a new family of cathodes with the potential to replace the costly cobalt-based cathodes typically found in today's lithium-ion batteries that power electric vehicles and consumer electronics. The new class called NFA, which stands for nickel-, iron- and aluminum-based cathode, is a derivative of lithium nickelate and can … [Read more...] about New class of cobalt-free cathodes could enhance energy density of next-gen lithium-ion batteries

Super-fast quantum computers and communication devices could revolutionize countless aspects of our lives -- but first, researchers need a fast, efficient source of the entangled pairs of photons such systems use to transmit and manipulate information. Researchers at Stevens Institute of Technology have done just that, not only creating a chip-based photon source 100 times more … [Read more...] about Scientists create entangled photons 100 times more efficiently than previously possible

Researchers at the George Washington University, together with researchers at the University of California, Los Angeles, and the deep-tech venture startup Optelligence LLC, have developed an optical convolutional neural network accelerator capable of processing large amounts of information, on the order of petabytes, per second. This innovation, which harnesses the massive … [Read more...] about Developing smarter, faster machine intelligence with light: Researchers invent an optical convolutional neural network accelerator for machine learning

A research group led by Associate Professor YAGUCHI Takaharu (Graduate School of System Informatics) and Associate Professor MATSUBARA Takashi (Graduate School of Engineering Science, Osaka University) have succeeded in developing technology to simulate phenomena for which the detailed mechanism or formula are unexplained. They did this by using artificial intelligence (AI) to … [Read more...] about Artificial Intelligence that can run a simulation faithful to physical laws: Replicating energy conservation and dissipation using digital analysis

Quantum computers have already managed to surpass ordinary computers in solving certain tasks -- unfortunately, totally useless ones. The next milestone is to get them to do useful things. Researchers at Chalmers University of Technology, Sweden, have now shown that they can solve a small part of a real logistics problem with their small, but well-functioning quantum … [Read more...] about Tiny quantum computer solves real optimization problem

Artificial intelligence is classifying real supernova explosions without the traditional use of spectra, thanks to a team of astronomers at the Center for Astrophysics | Harvard & Smithsonian. The complete data sets and resulting classifications are publicly available for open use. By training a machine learning model to categorize supernovae based on their visible … [Read more...] about Artificial intelligence classifies supernova explosions with unprecedented accuracy: A new machine learning algorithm trained only with real data has classified over 2,300 supernovae with over 80% accuracy

When you're responsible for a multimillion-dollar satellite hurtling through space at thousands of miles per hour, you want to be sure it's running smoothly. And time series can help. A time series is simply a record of a measurement taken repeatedly over time. It can keep track of a system's long-term trends and short-term blips. Examples include the infamous Covid-19 curve of … [Read more...] about Method finds hidden warning signals in measurements collected over time: A new deep-learning algorithm could provide advanced notice when systems — from satellites to data centers — are falling out of whack.

Researchers at the University of Pittsburgh School of Medicine have combined synthetic biology with a machine-learning algorithm to create human liver organoids with blood- and bile-handling systems. When implanted into mice with failing livers, the lab-grown replacement livers extended life. The study, published today in Cell Systems, shows that it's possible to trigger and … [Read more...] about Synthetic biology and machine learning speed the creation of lab-grown livers

More than half of the matter in our universe has so far remained hidden from us. However, astrophysicists had a hunch where it might be: In so-called filaments, unfathomably large thread-like structures of hot gas that surround and connect galaxies and galaxy clusters. A team led by the University of Bonn (Germany) has now for the first time observed a gas filament with a … [Read more...] about Longest intergalactic gas filament discovered: Study confirms models on the evolution of our universe
