How can jellyfish sting without ever touching you? 🪼

After 500 million years of peaceful drifting, moon jellyfish are turning dangerous. Off of Cape Cod in the U.S., swimmers are being stung, sometimes just by mucus in the water. Scientists have identified a DNA signature in these jellies, pointing to a possible mutation or previously unknown invasive species. As climate change reshapes ecosystems, research institutions are racing to understand and contain the threat, before it spreads across the globe.
