Laser Reveals Photosynthetic Processes
Scientists have used an ultrafast laser to study a photosynthetic complex — arguably the most important bit of organic chemistry on the planet — in its complete functioning state. When sunlight strikes a photosynthesizing organism, energy flashes between proteins just beneath its surface until it is trapped as separate electric charges. These tiny hits of energy are literally...
