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 ...

Researchers created a system that enables makers to incorporate sensors directly into rotational mechanisms with only one pass in a 3D printer. This gives rotational mechanisms like gearboxes the ...

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 ...

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 ...
