Jellyfish Glow Tracks Gene Activity
The green fluorescent protein from jellyfish glows under UV light. Scientists use it to track Tbx18 gene expression during biological pacemaker development. This technique, refined last year, shows cellular changes instantly rather than waiting days or weeks. Researchers can now see exactly how genes behave in real-time during heart cell transformation. This glowing protein revolutionized biological research by making the invisible visible without damaging living cells.
