Experiments show that ATP synthase motors achieve maximum efficiency with steady, continuous motion, minimizing energy loss compared to more variable force applications. doi.org/g95zcw

This was a stimulating and thoroughly enjoyable melding of experiment and theory. Special salute to lead author Takahide Mishima and the rest of Shoichi Toyabe’s group at Tohoku, former postdoc Deepak Gupta, and current grad student Callum Wareham @sfuphysics.bsky.social @sfuscience.bsky.social

Is it more efficient to push a molecular motor with a constant force, or at a constant velocity? See our collaborative paper in @physrevlett.bsky.social doi.org/10.1103/b24h... and the Focus article physics.aps.org/articles/v18... to learn the winner and the why (it’s all about the fluctuations).
