Shark blood offer hope for new medicines

Antibodies in shark blood could potentially be a potent weapon in the fight against cancer, Australian scientists have found.

Sharks have immune systems similar to humans, but their antibodies - the molecules which actually fight disease - are exceptionally resilient.

Researchers believe this quality could be harnessed to help slow the spread of diseases such as cancer.

Potentially, it could lead to a new generation of drug treatments.

The Australian team found that shark antibodies can withstand high temperatures as well as extremely acidic or alkaline conditions.
