    ‘Nanomagnetic’ Computing can provide Low-energy AI

    May 6, 2022, Categories  Physics, Technology/Electronics

    Researchers have shown it is possible to perform artificial intelligence using tiny nanomagnets that interact like neurons in the brain. The new method, developed by a team led by Imperial College London researchers, could slash the energy cost of artificial intelligence (AI), which is currently doubling globally every 3.5 months.

    In a paper published today in Nature Nanotechnology, the international team have produced the first proof that networks of nanomagnets can be used to perform AI-like processing. The researchers showed nanomagnets can be used for ‘time-series prediction’ tasks, such as predicting and regulating insulin levels in diabetic patients.

    Artificial intelligence that uses ‘neural networks’ aims to replicate the way parts of the brain work, where neurons talk to...

    As Wi-Fi is deployed more widely in cities, and perhaps at higher frequencies, it may depend on an abundant urban asset: streetlight poles.

    To help ensure these networks work well, researchers at the National Institute of Standards and Technology (NIST) have developed and verified a novel mo...

    The new technology could make at-home diagnosis of diseases faster and more affordable. A University of Minnesota Twin Cities research team has developed a new microfluidic chip for diagnosing diseases that uses a minimal number of components and can be powered wirelessly by a smartphone. The innovation opens the door for faster and more affordable at-home medical testing.

    The researchers’ paper is published in Nature Communications, a peer-reviewed, open access, scientific journal published by Nature Research...
