- New Technique Takes Cues From Astronomy And Ophthalmology To Sharpen Microscope Images
The complexity of biology can befuddle even the most sophisticated light microscopes because biological samples bend light in unpredictable ways, returning difficult-to-interpret information to the microscope and distorting the resulting image. New imagin ...
