There is no shortcut at the top right to quickly toggle or like there is for hidden posts. Not sure why. There is also a button that quickly clears the next 25 read posts. The + at the bottom right also has that button.

The authors show that stabilizing the microtubules network with epothilone B delays the onset of unconsciousness in rats under isoflurane anesthesia by one minute.

This suggests that a normal microtubules network is required for normal neuronal function. This is expected, considering the microtubules network is essential for cell shape and intercellular transport, among other things.

Taking this as evidence or even concluding that quantum microtubules vibrations are responsible for consciousness is a very big stretch.

I’m also unclear why this would be specific to neurons or higher animals for that matter. Virtually every eukaryotic cells has microtubules.

tl;dr: me no likey.

Today I learned that MALDI-proteomics is used for identification of bacteria. I expected sequencing to be the gold standard.

Is it a highly targeted approach where you can guarantee coverage of proteins of interest? On average, how many proteins contribute to the fingerprint of a bacterium?
