A molecule found in sharks appears to be able to wipe out human liver viruses, such as hepatitis, new research has found.
"Sharks are remarkably resistant to viruses," study researcher Michael
Zasloff, of the Georgetown University Medical Center, told LiveScience.
Zasloff discovered the molecule, squalamine, in 1993 in the dogfish
