When I woke up this morning the centigrade temperature was three times the fahrenheit temperature. But by 9 AM it was already 10 times the fahrenheit temperature and the ratio was climbing at a dizzying rate!

In a long-form piece, I address recent claims by the Editor-in-Chief of @science.org that "quiet" insiders rather than "heated" activists should be credited for passage of top-line budget numbers for science and medical research.

Accounting for heterogeneity among hosts, even if done very simply, can have dramatic effects on models' ability to parse out patterns.
Updating conventional epidemic models to account for assortativity aligns realized and predicted breakthrough infections.

Why indeed? Because it's exactly what you would expect. The shots are excellent -- and led to "measles-elimination status". But they're not perfect.
The MMR vaccine provides durable protection against measles for most people. Most infections in the US are in unvaccinated people. But rare instances of breakthrough infections are amplified by anti-vaccine influencers to suggest vaccines are ineffective.

Measles is spreading. The number of cases in vaccinated people will continue to go up (although not as fast as the number in unvaccinated people). These "breakthrough" cases will be used for #antivax propaganda. Public health needs to be ready.
In a new preprint, we combine modeling with school-level vaccine data to contextualize the risk of 'breakthrough infections' and impacts on the ongoing US measles outbreak. #idsky #episky

This is exactly why there used to be processes for making decisions, and protocols for carrying them out. The _way_ they do things like cut USAID is actually worse than the _fact_ that they do them.

It also dovetails with something that stuck in my mind: you can now be called a “domestic terrorist” simply for _observing_, before you even say anything. That seems pretty revealing.

Until now, [the Reporters Committee for Freedom of the Press] said, the Justice Department had “never executed a search warrant at the home of a reporter in a national security leak case.”

Inside The Washington Post, the impact was immediate. Reporters called the search “incredibly disturbing.” Hannah Natanson, whose home was raided, urged her Post colleagues to keep reporting.

Viral genes sometimes use certain codons more than others due to their nucleotide content, translational efficiency, and selection pressure from the host immune system. The rabies virus (RABV) is a ne...
