Trump Can’t Cap Overhead Rate on NIH Grants to Research Universities, Appeals Court Rules
The ruling is a victory for higher-education associations who challenged the proposed 15-percent cap, calling it illegal and claiming it would devastate the research enterprise.

How much better is an ancestral recombination graph (ARG) than a site frequency spectrum (SFS)? For recovering mutation rate history, we can answer fairly precisely because both ARG and SFS are linear transforms of mutation rate history. This blog post uses spectral analysis to clarify the picture.

The point is much broader than poliovirus and pocapavir: if we're trying to design therapeutics that exploit social interactions between viruses, we need to account for the effects of therapeutic success in diminishing those interactions.

Big picture: the feedback loop between viral density leading to social interaction, which leads to realized phenotype, which alters fitness, leading to new viral densities, should be considered when designing optimal treatments.

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)
