It was surreal to be quizzed on “freedom of inquiry” and other values in my mandated U. Chicago/NIH/NSF research security training tonight given the restrictions to our research over the past eight months. Jeremy describes the experience perfectly below. (His piece is outstanding.)

Immigrants, particularly on H1Bs, are the lifeblood of American innovation. If you wanted to hurt US competitiveness in the next century, I can think of few more effective ways than a move like this

Even when found illegal, the mere intent will have irreparably harmed our future

This doesn’t affect your main point, but I think the imprinting/“original antigenic sin” hypothesis, in which differences in mortality arise from differences in early influenza exposures by birth cohort, has much more support.

But it does not *want* to do that. It has the personality and confidence of a 10x coder, and *absolutely lies to your face* to maintain the illusion.

It races to establish huge frameworks, call up parallel agents, and build you something that gives an output.

Removed datasets: "Percent Positivity of Viral Detections Among Enrolled Children in the New Vaccine Surveillance Network (NVSN), Acute Respiratory Illnesses (ARI), 2017–Present" and "Pathogen Detections Among Enrolled Children in the New Vaccine Surveillance Network (NVSN), Acute Respiratory Illnesses (ARI), 12 Month Rolling Period"

NEW: I just observed two interesting data deletions from the CDC's website. Both having to do with vaccine surveillance in children. There's nothing about these datasets that would have tripped any "gender" flags.

Just few days left to apply to one of these postdoc positions in my infectious disease modelling Unit at @pasteur.fr in Paris!

Overall, quantifying pathogen resilience offers a new perspective on understanding how pathogens respond to both large and small perturbations. These insights have important implications for pathogen persistence, prediction, and model validation. [7/8]

We've focused on resilience in the context of large perturbations. We also showed that resilience determines how sensitive a system is to smaller stochastic perturbations, with less resilient systems exhibiting greater deviations from deterministic trajectories under demographic stochasticity. [6/8]

What determines how resilient a pathogen is? It depends on the per-capita rate of replenishment of the susceptible population. Faster replenishment = more resilient dynamics, where the rate of replenishment depends on the duration of immunity and basic reproduction number (R0). [5/8]

We estimated that common respiratory pathogens are much more resilient than vaccine-preventable infections, such as measles. Our predictions about pathogen return also closely match the observed deviations (or lack thereof) from the pre-COVID dynamics of respiratory pathogens. [4/8]

We analyzed relevant time series data from Hong Kong, Canada, Korea, and the US. By quantifying the resilience of common respiratory pathogens, we could predict when each pathogen would eventually return to its pre-pandemic dynamics. [3/8]

COVID-19 interventions disrupted the circulation of many pathogens. To understand if and when they might return to pre-pandemic patterns, we developed a framework for quantifying the rate of return to pre-pandemic patterns—a measure of pathogen resilience in a given host population. [2/8]

Sang Woo (Daniel) Park and I are excited to share a new preprint, "Susceptible host dynamics explain pathogen resilience to perturbations" [1/8]

UC Berkeley researchers team up for first-of-its-kind lawsuit over Trump funding cuts University of California staff members hope to use a class action lawsuit to restore their research funding.

More of this, please: a class action lawsuit by UC Berkeley researchers to restore illegally cut federal grants. www.nbcnews.com/news/us-news...

NSF, NASA and NIH budgets per year, inflation adjusted from 2000-2025 along with the proposed cuts. NSF includes research component only. Massive cuts across all sectors, well below support spanning 25 years.

How bad will it be? Catastrophic.

Proposed cuts to #NSF, #NIH, and #NASA will set the US R&D landscape back 25 yrs+, cause economic and job loss now, and undermine innovations to come.

But, this is the WH's *proposed* budget.

Speak up now before it is too late.

SA universities face funding crisis as US federal agencies freeze research grants | News24 An investigation into the impact of the US aid freeze on research funding to South African universities has found that 44 programmes worth R2.5 billion were affected.

A not very happy Friday. CERI had 6 NIH grants canceled, which will impact operations, surveillance and response to epidemics. We are working to try to minimize disturbance but not easy with 6 grants terminated at the same moment. A crisis is unfolding in SA www.news24.com/southafrica/...

I was working on a proposal in response to one of these calls. Submission deadline next week. The proposal was 95% done, and I only learned about the cancellation from this post. 🤷‍♂️

Tbh I'm reading a review right now that completely misses some of our important contributions to a topic. Meanwhile it incorporates unnecessary jargon from some splashy articles in glam journals. In a dark reflective mood.

Unfortunately there's a risk people might not even notice your discovery unless it's in such a journal. Good work should speak for itself but it obviously doesn't fully. Sometimes I see publishing in 'higher impact' journals as a shortcut to having to give so many talks/wait for discovery.

This is such an important point. The timescales for lawsuits are much too slow to prevent the tremendous damage already occurring.

Yes, that’s exactly what they are doing. They are trying to hurt Harvard by destroying my research

PO

I've been advised to request the NCE as usual and wait until there is a request to terminate a foreign subaward.

Exclusive: NSF faces radical shake-up as officials abolish its 37 divisions Changes seen as a response to presidential directives on what research to fund

Things are going from bad to worse at NSF; www.science.org/content/arti...

But it seems disingenuous to bluntly and severely penalise researchers (and with zero advance notice) for focusing on issues that you’ve built your own career on.

A large fraction of NIH project periods end June 30, so funding is needed in two months, if not immediately for termination notices already received.

This is disastrous for many scientific fields and labs.
