French authorities on Tuesday froze Iran’s Intelligence Ministry assets related to internal security and the assets of two Iranians in response to an alleged bomb plot that was thwarted earlier this year. The French interior, economy, and foreign ministers said in a joint statement that there was a plan to detonate explosives at a June rally near Paris by the People’s Mujahadeen of Iran, an Iranian exile group. “This act of an extreme gravity envisioned on our territory could not go without a response,” the statement read.

The Nobel Prize in physics was awarded Tuesday to an international trio of scientists for their work on lasers. American Arthur Ashkin of Bell Laboratories in New Jersey became the oldest Nobel laureate ever at age 96. Canadian Donna Strickland of the University of Waterloo is only the third woman to have won a Nobel Prize in physics—the last was Maria Goeppert-Mayer in 1963, and the other was Marie Curie in 1903. The third laureate in physics this year is Frenchman Gerard Mourou of the Ecole Polytechnique and the University of Michigan.

U.S. researcher James Allison of the University of Texas shared the 2018 Nobel Prize in medicine Monday with Tasuku Honjo of Kyoto University for lifesaving cancer research. Allison and Honjo will share the $1.01 million prize for their research into how to help the body marshal its own defenses against invading cancers.

Tesla stocks slid on Friday after government securities regulators asked on Thursday for the removal of Elon Musk as CEO of the electric car company. The Securities and Exchange Commission asked the U.S. District Court in Manhattan to bar Musk from serving as an officer or director of a public company. The complaint says that Musk’s claim on Twitter in August that funding was secured for Tesla Inc. to go private at $420 a share was false and amounted to securities fraud. Musk and the company’s board later said they decided not to go private after all.
