Scientists have uncovered an elegant biophysical trick that tuberculosis-causing bacteria use to survive inside human cells, a discovery that could lead to new strategies for fighting one of the world ...

Researchers have identified a novel mechanism by which bacteria form membrane vesicles, which bacteria employ to communicate with each other or to defend themselves against antibiotics. By studying ...

Our cells are surrounded by a fragile membrane that's only 5 nanometers thick, 1/20 of a soap bubble. Cells are easily damaged by physiological activities, including muscle contraction and tissue ...

Just as countries import a vast array of consumer goods across national borders, so living cells are engaged in a lively import-export business. Their ports of entry are sophisticated transport ...

Schematic of an active cell membrane. In a typical active biological process, active proteins (shown in a variety of colors) in a cell membrane (shown in blue) interact with various biological ...

Scientists describe the design and construction of artificial membrane channels, engineered using short segments of DNA. The DNA constructions behave much in the manner of natural cell channels or ...
