DNA lets sharks take a bite out of cancer
USA Today published an article on January 30, 2017 entitled: “Could sharks be the key to solving human cancer?”
A new study of shark DNA shows that unique evolutionary changes in immunity genes may explain how sharks’ open wounds heal so fast and why the ocean’s top predator rarely gets cancer.
But, scientist warn, simply eating shark meat or other parts won’t help humans battle cancer. In fact, eating sharks could be detrimental to human health because of high levels of mercury found in these “apex predators.”
