More than 150 died when a twister tore through Joplin in 2011, making it the deadliest tornado in the last seven decades.

Clinicians and their patients with chronic kidney disease (CKD) need to be aware of zinc intake and anemia status.

Dr. McCormack explained that zinc is ingested with food, whereby less of the heavier isotope zinc-66 than the lighter isotope zinc-64 is stored in muscles and organs.

Muscles and organs contain more zinc-64 isotopes than zinc-66, and as a result, animals with meat and fish-heavy diets will have more zinc-64 in their systems.

But Dr. McCormack’s team found that the zinc-66 content in the megalodon teeth they studied did not differ as greatly as expected from that of species lower down the food chain.

To figure this out, scientists looked at the isotope signatures in megalodon teeth. They looked specifically at zinc-64 and zinc-66, common zinc isotopes which are absorbed when animals eat.

Muscles and organs absorb more of the isotope zinc-64 than zinc-66, meaning that the higher up the food chain an animal is—or the more meat and fish it eats—the less zinc-66 it absorbs, and ...

Different types, or isotopes, of zinc are absorbed when fish and other animals eat, but one of them — zinc-66 — is stored in tooth enamel much less than another, zinc-64.
