• Scientists built a camera that can track invisible particles in 3D
  A new particle detector called PLATON could replace millions of tiny detector components with a single block of light-producing material. Using a light-field camera, highly sensitive photon sensors, and AI, it reconstructs particle paths in fast, detailed 3D. Simulations suggest it could match or surpass today’s best detectors while being far easier to scale. The technology may also lead to sharper PET medical scans.
• NASA’s James Webb catches a supermassive black hole feeding
  JWST has captured unusually detailed images of gas feeding the supermassive black hole at the center of NGC 4696. A vast filament appears to funnel material into an 800-light-year-wide spinning disk, where gas races around at up to 600 kilometers per second. The findings suggest black holes may recycle their own fuel by heating gas with jets and later drawing the cooled material back in.
