And this image is a little different: it captures the powerful magnetic fields that are acting as the cosmic cutlery feeding mass into the singularity. Avery Broderick is part of the Event Horizon Telescope team, he’s also a professor at the University of Waterloo’s Department of Physics and Astronomy, and associate faculty at the Perimeter Institute for theoretical physics.Decoding how chickadees maintain a mental map of their food cachesChickadees have an uncanny ability to recall thousands of secret stashes of food with a centimetre-scale precision. Salmaan Chettih, a postdoctoral researcher in neuroscience at Columbia University, investigated how chickadees encode their internal treasure maps. In his study in the journal Cell, he found the chickadee brains produce a unique pattern of activity — akin to a neural “barcode” — that marks t
