Researchers have created the largest synaptic-resolution, 3D reconstruction of a piece of human brain to date, showing in vivid detail each cell and its web of neural connections in a piece of human temporal cortex about half the size of a rice grain.

Most people with early-stage glaucoma don't know they have it, even though early treatment is key to reducing vision loss. While detecting a subtle increase in eye pressure helps doctors to diagnose glaucoma, it's challenging to monitor continuously, especially with the variety of temperatures eyes experience. Now, researchers report a prototype 'smart' contact lens that measures eye pressure accurately, regardless of temperature.
