Jellyfish glow lights up medical imaging
A glowing protein from jellyfish transformed medical imaging, enabling scientists to visualize cellular processes in living organisms with unprecedented precision and without invasive procedures.
The green fluorescent protein (GFP), first found in bioluminescent jellyfish, has revolutionized medical imaging. This protein naturally glows bright green under blue or UV light, a trait jellyfish evolved for underwater luminescence. Scientists learned to use GFP to tag specific proteins and cells, earning a Nobel Prize in 2008 for Osamu Shimomura, Martin Chalfie, and Roger Tsien. Today, GFP allows researchers to non-invasively track dynamic processes inside living bodies, from observing tumor growth to visualizing brain activity. This innovation provides real-time, non-toxic imaging, accelerating discoveries in fields like neurology and oncology.
