Australian researchers find antidote for world's most venomous creature

Researchers at the University of Sydney have found an antidote for the sting of the jellyfish – which carries enough venom to kill more than 60 people.

A single sting from the creature will cause excruciating pain and skin necrosis and, if the dose of venom is large enough, cardiac arrest and death within just minutes.

Using genome editing, pain researchers at the university’s Charles Perkins Centre found a “molecular antidote” that blocks the symptoms of a box jellyfish sting if applied to skin within 15 minutes.

The researchers took millions of human cells and knocked out a different human gene in each one, before adding the jellyfish venom and looking for cells that survived the process.
