According to Deshevaya et al., 2024 numbers reduced and survival is due to lyophilization.

So they were not growing, but preserved.

Still cool though.

Thanks! I corrected it.

In case anyone was wondering the same: The zinc spark is the release of zinc by the egg upon fertilization. It is called spark because the researchers used a fluorescent probe for detection. There is no light emitted upon conception if the probe is not present. The exact reason for the release of zinc is still unknown.

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?
