Functional mechanical gear discovered in nature (2013)

And here&#x27;s the paper describing their findings:<p><a href="http://www.sciencemag.org/content/341/6151/1254" rel="nofollow">http:&#x2F;&#x2F;www.sciencemag.org&#x2F;content&#x2F;341&#x2F;6151&#x2F;1254</a><p>Of course as soon as I submit I think of a better title, mechanical-style gear is probably more appropriate.

It&#x27;s odd -- I&#x27;d swear I&#x27;ve read about a gear-like mechanism found in an insect years ago, but I can&#x27;t find any references now... of course Google is flooded with a million articles rehashing this single news story claiming to be the first.<p>It may just be that late 2013 feels farther than it is, and I&#x27;m remembering this news from then.

ATPase is gear-like and present in all living things (to the best of my knowledge): <a href="http://www.psc.edu/science/schulten2004.html" rel="nofollow">http:&#x2F;&#x2F;www.psc.edu&#x2F;science&#x2F;schulten2004.html</a>

This is only a story for those who ascribe some special property to a mechanical gear.
