Slimy, hard-to-clean bacterial mats called biofilms cause problems ranging from medical infections to clogged drains and fouled industrial equipment. Now, researchers at Princeton have found a way to cleanly and completely peel off these notorious sludges.
Creating new tools that harness light to probe the mysteries of cellular behavior, Princeton researchers have made discoveries about the formation of cellular components called membraneless organelles and the key role these organelles play in cells.
For centuries, scientists have puzzled over configurations of objects that fit a given space. These packing problems not only have fascinated mathematicians, they also hold critical implications for disciplines from chemistry to shipping.
