Radioactive leftovers from Eisenhower-era bomb tests could help save the African elephant from extinction, thanks to a team of scientists.
The team led by a researcher now at Columbia University’s Lamont-Doherty Earth Observatory in Rockland has developed a forensic technique that it says will cut down on elephant poaching and the illegal ivory trade. The method determines a tusk’s age, revealing if it was acquired before or after a 1989 ban on trade in African elephant ivory.
The study was published this month in the Proceedings of the National Academy of Sciences.
