Macedo and Lee misrepresent what happened during the pandemic and are unable to confront Covid's actual toll, presumably because it undermines their premise. A longer take here w/my colleague Greg Gibson:

My first lead author paper is out with Ben Kerr and @alisonfeder.bsky.social! We found that making an antiviral too strong can sometimes make resistance easier to evolve. This has implications for how we design drugs, choose doses, and think about viral evolution in the face of treatment. (1/n)

Check out our latest paper on mirusviruses, one of the most remarkable new groups of protist viruses - extremely diverse, carry lots of spliceosomal introns (including new homing introns) and are at the evolutionary crossroads between tailed phages and herpesviruses! www.nature.com/articles/s41...
Widespread and intron-rich mirusviruses are predicted to reproduce in nuclei of unicellular eukaryotes - Nature Microbiology
Environmental metagenomic explorations show that Mirusviricota lineages lack essential replication and transcription genes and contain spliceosomal introns, suggesting nuclear reproduction.

This is wild.
Remember the NJ crytic lineage?
I posted 18 months ago that the Spike was too divergent to predict ACE2 binding, and asked if someone else could figure it out.
Some colleagues took me up on it.
Guess what they found?

RFK fired the CDC official (w/decades of experience) leading the measles outbreak response. It's been decades since we've had such a large outbreak. And just to ensure they they can spread the measles outbreak even farther, they also fired the leadership for the center focused on immunization.
