Another beautiful Shchedryk performance amidst ruins. It was set in what used to be a DTEK thermal power plant — now destroyed by russia. The contrast between russia’s destructive nature and the Ukrainian will to create beauty even in the darkest times is palpable.

log-transform the world and keep thinking linearly 😀 (not to make fun of @adamjkucharski.bsky.social's wonderful educational and outreach efforts; just couldn't keep the math nerdiness under control)

On Oct 1, 2025, GISAID informed us that they had ended updates to the flat file of SARS-CoV-2 genomic sequences and associated metadata that we had used to update Nextstrain analyses since Feb 2020. GISAID's stated rationale was that their "resources are limited". 1/5

I am not an expert on the early SARS-CoV-2 evolution, but this looks like a thorough study. It is also important given a big splash @jbloomlab.bsky.social's recovered sequence analysis made back in 2021

Four years ago, Jesse Bloom announced the recovery of SARS-CoV-2 sequences and suggested they could come from very early COVID-19 patients. Zach Hensel and I found out that Bloom's claim relied on the deliberate omission of a January 30, 2020 collection date contradicting his narrative. 🧪 #PopGen
