Researchers borrowed optical techniques from astronomy and ophthalmology to dramatically improve imaging of biological samples. This video, created by scientists at the HHMI Janelia Farm Research Campus, shows neurons in the brain of a living zebrafish embryo. You can see the difference in quality when their new technique of “adaptive optics” is switched on and off. According to physicist/engineer Eric Betzig who led the research, “The results are pretty eye-popping.” Yes. Yes they are. ( HHMI News , via National Geographic )
