GREEN REVOLUTION: HYDROGEN

submitted by: nsf
Host Lisa Van Pay meets with NSF-funded scientists Yang-Shao Horn and Yogi Surendranath at the Massachusetts Institute of Technology as they take on the hydrogen energy challenge. Hydrogen bonds are an extremely efficient way to store energy, and scientists would like to capture this energy to power all sorts of things—from cars to laptops. Unlike other fuel sources, hydrogen can’t be harvested easily, so we have to make it. From the importance of developing an effective catalyst to...

Advances in Proton Therapy, Pencil Beam Technology Reach Patient Care

submitted by: mdanderson

In treating cancer, the pencil beam technology for proton therapy delivers a single, narrow proton beam (about a centimeter in diameter) that is magnetically swept across the tumor, depositing the radiation dose like a painter
