Nobelium is a chemical element discovered simultaneously in the early 1960s by two groups of scientists, one in the University of California in the US, and the other in Moscow, Russia. It is a very radioactive and toxic metal which is produced in nuclear reactors from another radioactive element, curium. Nobelium was named after a famous Swedish engineer and scientist Alfred Nobel. Produced only in very small amounts, nobelium is used for research and has no biological importance.
