Transient RNA structures play a key role in the emergence of highly pathogenic avian influenza viruses! Great to see this collaboration with Mathis Funk, Mathilde Richard, Stephen Cusack, and others in @science.org www.science.org/doi/10.1126/...

The data is in: the NIH goalposts have shifted. What were once almost certain fundable scores have become coin flips and what used to be likely grants have become aspirational, leading to fewer awards. Another manifestation of how HHS policies have led to fewer awards and less science.

We found a viral Trojan Horse: a virus can hide inside another virus.This one surprised us: deltaviruses don’t just borrow a helper virus. They can travel inside it. A literal Trojan Horse “virus-in-a-virus” route into cells. 🤯 Kudos to 1st author @viroscope.bsky.social and co-authors !

Should biology put complexity first? www.sciencedirect.com/science/arti... - excellent essay by @philipcball.bsky.social. I would add epistasis to polygenicity and pleiotropy as a ubiquitous and fundamental phenomenon, not some optional complication that we can try to account for afterwards

Out today in @natecoevo.nature.com! 📝 www.nature.com/articles/s41... We compare the mutational tolerance of enteroviruses A & B across their full proteomes, mapping distinct host interaction strategies 🦠 and identifying mutation-resistant regions that could inform antiviral development 💊

Thank you to @joshuasweitz.bsky.social. The origin of the current assault on science and public health has a direct tie to COVID contrarianism. But Bhattacharya, Prasad and the rest couldn’t rise without help and patronage. 1/ joshuasweitz.substack.com/p/grievance-...

A lot of people, including me, were wondering how an IRB could ever approve this study. The answer is that no IRB did. The person who “signed off” on approval from the only ethics board that reviewed it had resigned three years earlier. His signature was used without his knowledge.

In 2020, we mapped out the danger zones that will close in on Americans over the next 30 years — combining climate data with wildfire projections by US Forest Service researchers and others. See what changes are in store for your county 👇

Scoop: Top FDA official Vinay Prasad overruled the agency’s reviewers when he refused to accept Moderna’s application for a new influenza vaccine, STAT has learned. www.statnews.com/2026/02/11/m...

Last week in Minnesota, I watched ordinary people risk their lives to protect their neighbors. In the process, they not only won a significant—though not final—victory against authoritarianism, they proved virtually every MAGA social theory wrong. (gift link) www.theatlantic.com/ideas/2026/0...

This is the chair of ACIP. Experimenting on America's kids. HE'S GOT TO GO. “What we’re going to have is a real-world experience of when unvaccinated people get measles,” he said. “What is the new incidence of hospitalization? What’s the incidence of death?” www.statnews.com/2026/01/22/v....

Beautiful work from @efodor.bsky.social and Jonathan Grimes' labs - the first full structure of the influenza A virus NEP protein, and a clear indication that its role in viral replication is more nuanced that first thought www.science.org/doi/10.1126/...

🚨 New from me: Grant review at more than half of NIH's institutes could be frozen by the end of the year. That's because crucial NIH grant-review panels are slated to be empty at those institutes by Jan 2027. A wonky bureaucratic problem with big implications. A short 🧵

Excited to share: We show that basal IFNλ2/3 signaling helps human intestinal epithelial cells stay ready for viral infections, even before an acute infection. A reminder that a lot of innate immune defense happens quietly in the background. journals.plos.org/plospathogen...

I came to Minneapolis to report on what's going on, and one of the main questions I showed up with is "just what is the scale of the resistance?" After all, we're all used to the news calling Portland a "war zone" or whatever when it's just some protests in one part of town.

Rhinoviruses cause common cold & asthma attacks but are also often benign. Using nasal organoids, we learned how the community of cells in the lining the nasal passages coordinates to respond to rhinovirus and which responses lead to excess mucus & inflammation. www.cell.com/cell-press-b...

Minnesota: "School officials say the [5-year-old] child was used as bait. They say [ICE] agents made little Liam knock on the door to ask to be let in in order to see if anyone else was home."

Now live! Nearly all human genes contain multiple transcript isoforms - and the genes that predominantly control infection, ISGs, are no different. Using PacBio with analysis help from Yan Guo, Himadri noticed a never-before-seen transcript isoform of ISG15 that potently restricts flu 1/4

The thing I always come back to is how many people never despaired against longer odds, and how arrogant it would be to put myself above them.

We find that subclade K viruses are antigenically advanced; however, this year's flu vaccine surprisingly elicited antibodies in many individuals that efficiently recognized these viruses. The implications are clear: go get this year’s vaccine if you haven’t already! www.medrxiv.org/content/10.6...

If you are submitting an NIH grant in February, you will be required to use SciENcv to prepare you biosketch. IT IS MUCH WORSE THAN YOU CAN POSSIBLY IMAGINE. Set aside *at least* 4 hours just to transfer an existing an biosketch into SciENcv.

Three weeks ago I explained in @statnews.com why adopting Denmark’s vaccine schedule would leave American children unprotected. Today HHS did it anyway. www.statnews.com/2025/12/19/d...

Happy to see @joelrc.bsky.social's paper identifying cellular heterogeneity in basal OASL expression as a major determinant of interferon induction during influenza virus infection out in its final form: www.pnas.org/doi/10.1073/... Happy new year, hope everyone's 2026 is better than 2025!

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: joshuasweitz.substack.com/p/revisionis...

🧵 Thread on our new @natcomms.nature.com paper: TLDR -- ADP-ribosylation inhibits viral replication and represents a previously under-appreciated arm of innate immunity during flu infection. Read along for the details…. (1/11) www.nature.com/articles/s41...

Put a perspective piece together on how fever may have driven the evolution of antiviral genes: rupress.org/jem/article/...

Check out @lizthayer.bsky.social's new preprint exploring factors that influence cell-to-cell heterogeneity in interferon (IFN) induction potential!

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)

A study on 1.7 million people in Hong Kong shows superior hybrid immunity to Covid in people who got vaccinated before infection vs. people who got infected first. "Our findings are a direct rebuttal to arguments for natural immunity," the authors write. doi.org/10.1016/j.va...

Meet the head of a federal panel expected to upend the childhood vaccine schedule later this week. Dr. Kirk Milhoan believes that Covid was made in North Carolina and deployed to China as a bioweapon ... among other conspiracy theories. www.ms.now/news/rfk-jr-...

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? 1/

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.

NEW: @CDCgov hit hard by massive firings that several staff describe to me as a “bloodbath.” Among those RIFd: —leadership of the center for immunization and respiratory diseases; —leadership of global health center —leadership of the measles outbreak response; 1/4
