Artificial intelligence using neural networks performs calculations digitally with the help of microelectronic chips. Physicists at Leipzig University have now created a type of neural network that works not with electricity but with so-called active colloidal particles. In their publication in Nature Communications, the researchers describe how these microparticles can be used as a physical system for [...]
Since it was detected in August 2023, the JN.1 variant of COVID has spread widely. It has become dominant in Australia and around the world, driving the biggest COVID wave seen in many jurisdictions for at least the past year. The World Health Organization (WHO) classified JN.1 as a “variant of interest” in December 2023 and in January strongly stated COVID was a [...]
A study forecasts that by mid-2024, bad actors are expected to increasingly utilize AI in their daily activities. The research, conducted by Neil F. Johnson and his team, involves an exploration of online communities associated with hatred. Their methodology includes searching for terminology listed in the Anti-Defamation League Hate Symbols Database, as well as [...]
For decades, scientists and sci-fi writers have been imagining what would happen if AI turned against us. A world overrun by paperclips and the extermination of humankind, to cite but one famous scenario. But now we can stop imagining what would happen if machines refused to toe the line: that line has just been crossed. A new study [...]
Princeton researchers have learned to harness the gossamer scaffolding that maintains the structure of living cells and used it to develop a nanotechnology platform. The technique eventually could lead to advances in soft robotics, new medicines, and the development of synthetic systems for high-precision biomolecular transport. In an article, "Building on-chip cytoskeletal circuits via [...]
Researchers from the University of Copenhagen have become the first in the world to mathematically prove that, beyond simple problems, it is impossible to develop algorithms for AI that will always be stable. ChatGPT and similar machine learning-based technologies are on the rise. However, even the most advanced algorithms face limitations. Researchers from the University of [...]
Researchers at City of Hope and Translational Genomics Research Institute (TGen) have developed and tested an innovative machine-learning approach that could one day enable the earlier detection of cancer in patients by using smaller blood draws. The study is published in the journal Science Translational Medicine. "A huge body of evidence shows that cancer caught at later stages [...]
Cryptocurrency is usually "mined" through the blockchain by asking a computer to perform a complicated mathematical problem in exchange for tokens of cryptocurrency. But in research appearing in the journal Chem a team of chemists has repurposed this process, asking computers to instead generate the largest network ever created of chemical reactions which may have given rise to [...]
A team of researchers from the Institute for Optoelectronic Systems and Microtechnology at Universidad Politécnica de Madrid (UPM) has designed a biosensor capable of identifying proteins and peptides in quantities as low as a single monolayer. For that, a surface acoustic wave (SAW), a kind of electrically controlled nano earthquake on a chip, is [...]
Cynthia Horton’s earaches are the stuff of nightmares. “I can wake up from my sleep in horrible pain, like I’m having a root canal with no anesthesia,” she said. “When I sit up, my ear is often weeping with infection, even oozing blood.” Already weakened by a lifelong battle with lupus, Horton’s immune system was [...]
