Microscope created allowing deep brain exploration

A team of neuroscientists and bioengineers has created a miniature, fiber-optic microscope designed to peer deeply inside a living brain. The laser-scanning microscope, a prototype which will be further refined, uses fiber-optics and a tiny electrowetting lens. Compared to other small, focusing lenses, it's fast and not sensitive to motion. This allows it to reliably focus on living tissue.
