Attention to Detail

Since the very first microscope revealed a hidden world, countless gradual improvements have exposed ever-deeper layers. This procession of progress eventually led to the electron microscope, able to show the very atoms of materials. But the electron beam – used in place of light – destroyed biological material, limiting its insights to the inert world. Determined to see not just matter, but life, at the finest detail, Richard Henderson – born on this day in 1945 – managed to expose a protein from a plant cell’s membrane to a reduced electron beam and picture its structure according to how the electrons bounced off (left, from 1975). With 15 years more work and the advent of cryo-electron microscopy, which freezes samples to shield from the electrons, he determined the structure at the ultimate resolution. In the process he gave the world a new viewpoint on life, and earned a share of a 2017 Nobel Prize.
