New microscopes reveal chemicals that were once invisible
Science
A breakthrough in imaging technology has exposed a 'ghost' layer of chemistry where vital molecular reactions were happening entirely in the dark.
For decades, the world of molecular biology had a blind spot for the fast and the faint. Traditional microscopes act like cameras with slow shutter speeds, meaning they often miss transient chemical signals that vanish in milliseconds. A new generation of microscopy has finally pulled back the curtain, utilizing advanced light physics to visualize these 'invisible' chemical interactions in real-time.
