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.

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
