A 75-Kilowatt Laser Just Solved Cryo-Electron Microscopy's Biggest Blind Spot
By trapping a laser 100 million times brighter than the sun inside an electron microscope, physicists have dramatically boosted image contrast, allowing scientists to finally see the smallest proteins in the human body.

Why this matters
More than 90 percent of the proteins inside human cells are currently too small to be seen by electron microscopes. By using a laser to dramatically boost image contrast, this breakthrough allows scientists to finally visualize the hidden molecular machinery that drives both fundamental biology and complex diseases, accelerating the discovery of new life-saving drugs.
