2019 London Calling
Field-Forward Sequencing with Oxford Nanopore Technology
Jellyfish expert Dr. Cheryl Ames presents at Oxford Naopre’s London Calling Aquatic Ecosystems plenary session. Dr. Ames discusses the work of her team at the U.S. Naval Research Laboratory using eDNA to categorize jellyfish diversity for environmental monitoring, sting prevention (affecting both combat divers in the Navy and recreational divers), to investigate biodiversity in the gulfstream, and also aid public aquariums.
SciShow Explains How Jellyfish Sting Without Touching You!
I Don’t Think You’re Ready for this Jelly!
SciShow’s Olivia Gordon discusses our recent discovery about Upside-Down Jellyfish and how they sting. This jellyfish might look kind of unassuming, but it’s got some surprising long-range weaponry to catch its prey!
The National Science Foundation Discusses Stinging Upside-Down Jellyfish
Researchers, with support in part by the U.S. National Science Foundation, have taken a close look at the cause of the “stinging water” encountered near these placid-looking creatures: a toxin-filled mucus the jellyfish release into the water. In the Feb. 13 issue of the journal Communications Biology, a journal from Nature Research, a team led by scientists at the Smithsonian’s National Museum of Natural History, the University of Kansas and the U.S. Naval Research Laboratory reports on microscopic structures they have discovered inside the mucus–gyrating balls of stinging cells that they call cassiosomes.
Jellyfish Can Sting You Without Even a Single Touch
Scientists have found that a species of the jellyfish throw venom grenades to create stinging water to snare their preys. The Cassiopea xamachana jellyfish, found in shallow waters around Florida, the Caribbean and Micronesia, is a frequent nuisance to snorkelers and surfers who appear to get stung without touching the creatures. It was thought that the stings came from detached tentacles or younger specimens. But a team from the U.S. Naval Research Laboratory realized that Cassiopea had in fact evolved a novel way of hunting without tentacles.
