New strategies are needed to address the current and future shortages of radioisotopes that threaten medical research and treatment.
Take a tour of the Linac Coherent Light Source (LCLS), whose ultra-powerful X-ray beam is being used to solve the structures of proteins that are notoriously hard to crystallize.
This animation illustrates optogenetics—a radical new technology for controlling brain activity with light. Ed Boyden, the co-inventor of this technology, is a professor at the MIT Media Lab and at the McGovern Institute for Brain Research, where he continues to develop new technologies for controlling brain activity.
“This is my trophy,” says biologist Michael Edidin, walking across his office at Johns Hopkins University to pick up two oversized clock hands, once part of the stately clock tower that still stands on the Baltimore campus. In his right-hand pocket i
