Detector advance could lead to cheaper, easier medical scans Posted: 29 Oct 2021 10:40 AM PDT Researchers have demonstrated the first experimental cross-sectional medical image that doesn't require tomography, a mathematical process used to reconstruct images in CT and PET scans. The work could lead to cheaper, easier and more accurate medical imaging.

Solving complex learning tasks in brain-inspired computers Posted: 29 Oct 2021 08:40 AM PDT Spiking neural networks, which mimic the structure and function of a natural nervous system, are powerful, fast, and energy-efficient. One key challenge is how to train such complex systems. An interdisciplinary research team has now developed and successfully implemented an algorithm that achieves such training. It can be used to train spiking neural networks to solve complex tasks with extreme energy efficiency.

Engineers develop better method for cleaning up orbiting space junk Posted: 29 Oct 2021 07:31 AM PDT Mechanical engineers have discovered a method of manipulating orbiting space debris with the use of spinning magnets, allowing agencies more dexterous movement in clearing out space junk or repairing satellites.
