After the war, Seaborg and his colleagues continued their research on the transuranium elements, discovering such elements as berkelium, californium, einsteinium, fermium, mendelevium, and nobelium.
Besides probing fermium further, the team plans next to study element number 101, mendelevium, Backe says.
