For years, brain imaging has been like staring through a foggy window—you can make out the surface clearly, but the deeper you try to see, the murkier it gets. Standard light-based microscopes are great for mapping the cortex, but when it comes to peering into deeper, more complex regions like the hippocampus, resolution collapses.
MIT researchers just shattered that barrier with the world’s first sound-powered microscope—a hybrid system that uses ultrafast bursts of light to trigger microscopic sound waves, then “listens” to those waves to build high-resolution images. The result: brain scans at five times the depth of existing methods, with zero dyes, chemicals, or genetic modifications.
