- Parrondo's Paradox
- In molecular biology and biophysics, molecular motors such as kinesin and myosin extract directed work from thermally randomized binding and unbinding cycles by alternating asymmetric potential phases — the Brownian-ratchet realization of the pattern.
This sourceBrownian-ratchet account of how motor proteins extract directed motion from thermal noise by cycling between asymmetric potential states.
Supported in partVerified against the publisher's abstract
The 1997 Science review's abstract states the Brownian-ratchet principle — fluctuation-driven transport biasing particle motion without gradients — but names no motor protein, so it backs the mechanism, not the kinesin/myosin examples.
“Nonequilibrium fluctuations, whether generated externally or by a chemical reaction far from equilibrium, can bias the Brownian motion of a particle in an anisotropic medium without thermal gradients, a net force such as gravity, or a macroscopic electric field.”

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
