50 years ago, Jardetzky proposed the alternating-access model, which has shaped the theoretical understanding of how substrates are carried across cell membranes. Two studies now demonstrate that ...

Integrating sensors into rotational mechanisms could make it possible for engineers to build smart hinges that know when a door has been opened, or gears inside a motor that tell a mechanic how fast ...

Smith and Chance 1 have reported the behaviour of coacervates in an alternating electric field. Earlier, Furedi and Ohad 2 observed similar behaviour by live red blood cells in isotonic sucrose ...
