For years, swimmers have felt a perplexing tingling in waters inhabited by upside-down jellyfish, even without direct contact. Now, Live Science delivers the definitive scientific explanation, thanks to the pivotal research co-led by Dr. Cheryl Ames!

The long-standing question of what causes this ‘stinging water sensation’ has finally been addressed. As Dr. Cheryl Ames, an associate professor of applied marine biology at Tohoku University, explains the initial scientific challenge:

“We knew it had to be something in the mucus.”

Her team’s methodical investigation led to the identification of ‘cassiosomes’ – microscopic, venom-filled structures released by the jellyfish – providing the clear answer.

This compelling Live Science article details the journey of scientific inquiry, highlighting the rigorous process that unveiled nature’s hidden mechanisms. We’re proud to see Dr. Ames’s dedication to solving marine mysteries recognized by Live Science, bringing clarity and understanding to a broader audience.
