Reporting in Environmental Science and Technology, researchers write of harvesting electricity from microbe-rich river sediments--enough to power a small LED bulb. Grant Burgess, a marine biotechnologist at Newcastle University, discusses the hunt for electron-burping bugs.
When doctors autopsied tuberculosis patients, they described finding round, white swellings, especially in and around the lungs. Medical historian Howard Markel describes how those potato-like growths led to the disease being called tuberculosis, from the Latin tuber.
