October 5, 2025 Dr. Angel Yanagihara is a leading biochemist and toxinologist internationally recognized for her groundbreaking work on venomous marine invertebrates—particularly the box jellyfish (Alatina alata) and bluebottle (Physalia physalis). Based at the University of Hawai‘i at Mānoa, she is an associate researcher at the Pacific Biosciences Research Center and directs the Pacific Cnidaria Research Laboratory. Her research dispels long-held myths about jellyfish stings and establishes evidence-based first aid protocols grounded in cellular and biochemical science. Working in partnership with the U.S. military, Dr. Yanagihara developed Sting No More®, a first-aid product line that neutralizes jellyfish venom and is now used globally in marine safety operations. A global leader in cnidarian envenomation science, Dr. Yanagihara’s research has shaped protocols for beach management, lifeguard response, and swimmer safety worldwide. Her real-life contributions to open-water safety were featured in the 2023 Netflix film Nyad, in which she was represented as part of the scientific and medical support team ensuring Diana Nyad’s successful Cuba-to-Florida crossing.
