Science: In December 2012, the US Congress expanded the law defining the sanctions against Iran in response to Iran’s continued pursuit of nuclear technology. One of the changes includes preventing all US citizens, regardless of who employs them, from interacting with employees of the Iranian government. US-based journal publishers had already been prevented from publishing research performed by Iranian scientists employed by their government. The updated law now prevents US employees of foreign publishers from editing or reviewing research by employees of the Iranian government. Nongovernmental research can still be handled by US publishers and US citizens, however.
