Diverse cellular processes require many tiny force-generating motor proteins to work in a team. Paradoxically, nature often chooses the weak and inefficient dynein motor to generate large persistent forces inside cells. Here ...

(Phys.org)—Physics researchers working at Brandeis University have created a gel that is capable of spontaneous movement. In their paper published in the journal Nature, the team describes how they created gel drops by ...
In a critical breakthrough in unraveling how molecular "motors" ferry proteins and nutrients through cells, Harvard scientists have produced high-resolution images that show how the "foot" of dynein—one of the most complex, ...

Cells can show a remarkable range of motility, creeping over substrates using a variety of pushes, pulls, stretches, and drags to get from A to B. This range of motion is achieved through the concerted efforts of motor proteins ...
