Thoughts on the defunding of disease cure research, origin of COVID, the executive order on so-called gain of function research, China’s advances in biotech, the spread of avian flu, and why the US needs to shed this fictional worldview ASAP for health and national security.

[Krutika Kuppalli, MD FIDSA @KrutikaKuppalli]

How are Public Health Officers going to take care of persons who get sick?

These are not persons who have experience in providing high levels of care for persons with this infection.

Also why would a PHS officer deploy knowing if they had an exposure that they wouldn’t be repatriated

In 2025, HHS issued stop work order for federal research lab that studies Ebola virus and other deadly pathogens and fired its director. This lab was a world leader in accelerating development therapies and vaccines for Ebola and other viruses. 1/

@angelasanford22 @dieworkwear @JohnGVibes If so he almost certainly used gel and so that wouldn’t happen

[Dr. Angela Rasmussen @angie_rasmussen]

Yes, please join us tomorrow. Our team of expert Zoonati will correct the lab leak conspiracy theories that @mattwridley will help @NIHDirector_Jay spread in service of the authoritarian destruction of American science.

People who are suffering are searching for answers, and what they encounter from trusted voices matters a lot. If we want real answers for chronic illness, we need to invest in the science that can actually deliver. Everything else risks making things worse.

[Gigi Gronvall @ggronvall]

I just finished The Deep Places by @DouthatNYT and have some thoughts. First: I am deeply sympathetic to anyone suffering from a chronic illness without clear answers or effective treatments. That experience- the pain, uncertainty, and dismissal is real, and too common.

[Gigi Gronvall @ggronvall]

But that’s not enough. When you have a platform this large, you don’t get to disclaim responsibility while still shaping how people think. Also as a pk, I'd add James 3:1: “Not many of you should become teachers… because you know that we who teach will be judged more strictly.”

[Shannon Watts @shannonrwatts]

Socrates in 460 BC: “The unexamined life is not worth living.”

Marcus Aurelius in 150 CE: “You have power over your mind—not outside events.”

Augustine of Hippo in 400 CE: “Do not go outside; return into yourself. In the inward man dwells the truth.”

Marc Andreessen in 2026:

[Friends of Bear Cat Rescue @feederofcats]

We are now forced to close intake and not help anymore cats until we find homes for the adoptable cats in our care. We literally have no more space and I'm having to say no to cats who will die without us.

all these kittens are still here.

Please share.

@angie_rasmussen Good endorsement for Plan B access!

@JReinerMD To be fair, he is doing his best to make sure that the NIH could not be called that, anymore.

[Barack Obama @BarackObama]

Congratulations to Indiana University and Coach Cignetti on winning their first College Football Playoff National Championship. One of the greatest turnarounds of all time.

Even if hospitalization isn’t required, rotavirus was deeply unpleasant. (The vaccine wasn’t available for my first kid). Who wants to see their child suffer, needlessly, when you can prevent it?

[Benjamin Mazer @BenMazer]

I'm still saddened seeing doctors lie like this. The goal of the rotavirus vaccine is mostly to reduce hospitalizations, but no mention of that (the death numbers are wrong too). He's also lying that the current vaccine was pulled off the market - that was a different vaccine.

[Arthur Caplan @ArthurCaplan]

I am a polio survivor. Post vaccine my peer kids stopped dying and didn’t need crutches. Those are the facts from an eyewitness. R fk jr is full of crap

[Gigi Gronvall @ggronvall]

@xriskology Imagine having the power to transform lives for the better, make a lasting difference that people will remember for centuries, and instead not only refrain from doing that, but directly cause an incomprehensible amount of misery and death. https://t.co/YC94oDkhV9
