cancer research
Biologist Nick Hum loads samples onto the Lab’s biological Accelerator Mass Spectrometer (AMS). Each sample passes through the AMS to be analyzed for extremely sensitive measurements of carbon-14-labeled molecules. Looking on are fellow biologists and team members Gaby Loots (center) and Kelly Martin. The researchers have developed a way to determine how many cancer cells it takes to initiate a tumor in another part of the body. Photo by Julie Russell/LLNL
