1. A bit of evolutionary biology. I'm really intrigued by a new perspective piece from Steve Frank that explores connections between how natural selection creates systems that generalize and recent work in machine learning about the surprising capabilities of massively overparameterized systems.

Generalization as the great leap in evolvability: insights from machine learning

Abstract. Natural selection encodes learned information in the genome. Learned solutions may be tuned specifically to past challenges, failing in altered e

I’ve officially resigned as Associate Editor for Frontiers in Systems Neuroscience. It used to be a reputable journal, but became a case study in how forced automation destroys academic integrity. 👇

In the end, researchers were left with a list of 14 pathogens that they are sharing “to help state health departments say, ‘OK, what are the priority pathogens we should keep on our radar?’” @alexvespi.bsky.social says. My @science.org story on a preprint assessing outbreak risks at the World Cup.🧪

Will the World Cup kick off disease outbreaks?

Don’t expect pathogens to steal the show, says research group that studied the risk of visiting fans spreading infections

There's been some high profile criticism of test-negative method for vaccine effectiveness, as well as counter-criticism. Yet remarkably little in media saying what the method actually does, why it's useful, what the limitations are, and how we can improve it. Great that John Drake wrote this:

Jay Bhattacharya Called Test-Negative Study Design ‘Crap.’ Here’s How We Know Whether Vaccines Measured With It Are Effective

Jay Bhattacharya dismissed the test-negative design as 'crap.' The biostatistics literature tells a different story.

A Canadian passenger from the cruise ship Hondius has likely tested positive for hantavirus, a health official told CBC. The patient, with mild symptoms, was hospitalized and is currently in stable condition. Again, this concerns a passenger.

Marc Veldhoen@marcveld.bsky.social · 5mo ago

WHO reports no new suspected cases on the ship heading to the Netherlands. They remain in regular contact with the captain, who says no one onboard currently shows symptoms.

"WHO’s assessment continues to be that the risk to health globally is low. So far, 11 cases have been reported, including 3 deaths. All 11 cases are among passengers or crew on the ship. 9 of the 11 have been confirmed as Andes virus, and the other two are probable", says @drtedros.who.int.

🔴 La passagère française symptomatique et rapatriée hier est positive à l'#hantavirus, annonce Stéphanie Rist sur France Inter. Son état de santé "s'est dégradé" dans la nuit, elle est hospitalisée à Bichat.

After 15 years of reporting on infectious disease outbreaks, what continues to fascinate me about them is the challenge of making high-stakes decisions under uncertainty. The hantavirus outbreak on the MV Hondius is a perfect example My story in @science.org is here (and a thread to come): 🧪 #IDsky

What to do with the passengers on the cruise ship hit by hantavirus?

Past studies of Andes virus offer scant evidence on transmission risks, and have sparked debate

I've spent yesterday and today talking to researchers across the globe trying to understand the hantavirus outbreak aboard the cruise ship MV Hondius. My story in @science.org is here (and some threaded thoughts coming): www.science.org/content/arti... 🧪 #IDsky

Cruise ship’s hantavirus outbreak puts researchers in uncharted territory

Questions about the culprit virus and its route of spread remain as health officials make plans for stranded passengers

Updates on the hantavirus situation from WHO (which we, beyond belief, are no longer part of). Seven suspected cases, three deaths. Case 1 boarded Apr 1, got sick Apr 6, died Apr 11. Likely Andes virus, given Argentina link. Consistent with infection before boarding. www.who.int/emergencies/...

The hantavirus outbreak is a stress test for WHO's IHR. Cape Verde should allow disembarkation if it has capacity The IHR requires a risk assessment, and there is no risk to the local pop. This happened during COVID & it's why the IHR were amended. We haven't learned our lesson
