Borrowing from Astronomy Sharpens Microscopic Images

April 14, 2014 12:00 pm | by Howard Hughes Medical Institute | News | Comments

The complexity of biology can befuddle even the most sophisticated light microscopes. Biological samples bend light in unpredictable ways, returning difficult-to-interpret information to the microscope and distorting the resulting image. New imaging technology rapidly corrects for these distortions and sharpens high-resolution images over large volumes of tissue.
