Iran could build a nuclear bomb within nine to 18 months if it decides to weaponize its atomic enrichment program, Foreign Affairs Minister John Baird says.

An antimatter atom has been measured and manipulated for the first time ever, by a Canadian-led team of physicists.

A team of Australian physicists has created the world's first functioning single-atom transistor, which could prove a critical building block toward the development of super-fast computers.

The UN nuclear watchdog says it has received an invitation from North Korea to resume monitoring parts of its atomic program.
