๐Ÿงช Many official government websites now have partisan propaganda about the government shutdown (as below for NIH/HHS)--this is an illegal violation of the Hatch Act. See the instructions below for registering your objection to this illegal use of government webpages for partisan propaganda.

Iโ€™m guessing those kinds of assertions are coming, never mind that of causes of death to be concerned about include the obsession with guns in America but with no corresponding gun laws whatsoever. You want to prevent unnecessary wrongful death, thatโ€™s where you start.

Speaking diplomatically when the person youโ€™re talking to is not basing anything they โ€˜thinkโ€™ on actual facts and reality IS somewhat crazy-making. I only try so hard, after that you have to call it off and tell them when they want to deal in reality, youโ€™re there for them.

Thereโ€™s a choice of whether or not to learn scienceโ€”if they donโ€™t want to learn, theyโ€™ll have to know that their opinion means nothing because they are willfully ignorant

I think we have to address the misinformation coming from this admin in particular and referring to the actual science, of the kind explained reasonably here. And I have worked with many brilliant scientists on the spectrum, and often appreciate their unique approach and perspective on our research.

Kristen Kroll (@kristenkroll) For those who have asked me about recent assertions by RFK Jr. regarding Tylenol and autism, please see this article and the NYT deep dive penned by Sam Wang, who has also studied this topic in depth....

Happy to speak with you further, as a prof in the life sciences at Washington U. My email is kkroll@wustl.edu and I can also reach out to youโ€ฆalthough Iโ€™m currently working on many grant applications and manuscript submissions so Iโ€™m more than a little over-committed at this fraught political time.

Weโ€™re still holding on for now, in part due to philanthropic support stepping in where the NIH is beyond sluggish. I think anyone wholly depending on federal funds will have problems these days, because the system is broken.

One can only hope, as we now need a prescription to qualify for a COVID booster, and likely the new variants will be worse than ever given declining herd immunity/vaccination.

Congratulations, Stephen! You saved our sanity for decades with incisive satire, brilliant commentary, kindness and humanity.

Will miss you dearly. And yes, reality DOES stillโ€”perhaps now more than everโ€”have a โ€œwell known liberal biasโ€.

This will isolate U.S. science from the global community โ€” and people WILL DIE as a result.

Your motto was โ€œProve Me Wrongโ€

Especially on guns, I think you were proved wrong, unless your grieving wife and children still believe that the cost of 2nd A in America is gun death.
And, now you arenโ€™t here to Prove me wrong.
