The world’s nuclear enrichment programs should be under international control to prevent the development of nuclear weapons after the new arms deal with Iran expires in 10 to 15 years, said Frank von Hippel, a senior Princeton University research physicist and a former security advisor during the Clinton Administration.

“We have 10 to 15 years to strengthen the non-proliferation machine,” von Hippel said, speaking at the Ronald E. Hatcher Science on Saturday public lecture Jan. 30 at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory.

Shannon Greco, a science education program leader at PPPL, has been named one of the YWCA Princeton’s “women of excellence” for her work with young women and disadvantaged youth, including her help in starting two all-girls robotics teams for the YWCA Princeton.

When astronomer Isaac Roberts showed a photograph of the Andromeda Nebula to the Royal Astronomical Society, it caused a huge sensation. “There were audible gasps in the audience,” astronomer Alan Hirshfeld told the audience at the first Ronald E. Hatcher Science on Saturday lecture at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory on Jan. 9.

“The professional astronomers had never seen such a clear image of the nebula,” Hirshfeld said.
