1/ Hey y'all, I'm excited to share my latest paper, which is out now in PNAS! We introduce FAVA, a statistical framework to measure compositional variability across microbiome samples. If you want to measure variability across a stacked bar plot, FAVA is for you! Paper: doi.org/10.1073/pnas...

We’ve suspected for a long time that rainfall variability increases with warming. Now, observations are long enough and of sufficient quality to prove it. Not enough rain, and then too much, exacerbates climate impacts and makes adaptation more difficult.

Anthropogenic amplification of precipitation variability over the past century
As the climate warms, the consequent moistening of the atmosphere increases extreme precipitation. Precipitation variability should also increase, producing larger wet-dry swings, but that is yet to b...

I'm sceptical that LLMs provide a meaningful economic benefit because of their variability
"Variability destroys variability" so when you apply the same tech, with the same variability dynamic, throughout an economy, whatever benefit it might intrinsically provide will wash out at scale
