Physicists fail to find mysterious ‘sterile neutrino’ particles

After decades of looking, physicists are no closer to discovering theorised particles that could help solve ongoing problems in physics Physics 27 October 2021 By Leah Crane Part of the MicroBooNE neutrino experimentCindy Arnold The hunt for mysterious theoretical particles known as sterile neutrinos has turned up empty again. Neutrinos are extremely light subatomic particles…

Genetically engineered bacteria could heal us from inside our cells

AI can turn a collection of 2D images into an explorable 3D world

Technology 25 October 2021 By Chris Stokel-Walker An artificial intelligence algorithm can transform still images into a high-resolution, explorable 3D world, with potential implications for film effects and virtual reality. By feeding the neural network a selection of images of a scene and a rough 3D model of the scene created automatically using off-the-shelf software…
