When downy woodpeckers pound wood with their beaks they hold themselves rigid like hammers & grunt like tennis stars to stabilise their core muscles at the moment of impact

Another useful reminder to not divide metabolic rate by body mass!

Sable Systems @sablesys.bsky.social · 18d

This classic work by Regnault & Reiset was published in 1849. It conclusively showed that correcting metabolic rate for body mass by dividing by body mass is a worthless & misleading technique. They knew better, unlike the legacy metabolic phenotyping companies today!

I've received an 'exclusive' invite to try Nature's new 'research assistant', which will burn down a forest to provide a 'summary of the paper' I'm reading and I have SUCH exciting news for them, that's called an 'abstract' and the actual authors already wrote it for me, no forest-burning required.
