Quite the resignation letter.
I know it's April Fool's Day, but is CDC actually eliminating HIV surveillance completely? Along with most or all of its programs to combat HIV?

Here's a thread detailing many of the devastating cuts to pandemic preparedness and antiviral drug research that were just announced. It is stupefying, inconceivable, pick your adjective, that we would kneecap our knowledge, our top researchers and our national health this way.

Pretty mind-boggling detail.
Thanks to @tgof137 for this summary of the latest report on #COVID and its origins. I am more inclined than he is to think the virus originated in a lab, but he rightly points out that evidence is wholly inconclusive and we've learned almost nothing new for 3 years.
Is @VivekGRamaswamy blaming FDA for the track record of the company he founded?

Anyone else having trouble w/MA Health Connector? Please dm me. I've been trying since Nov. 1 to shop plans but the website crashes every time. We are seven calls in with customer "assistance" and zero help. I can't be the only one - feels like a story.

I really appreciate people who take the time to pull citations and write a thoughtful post to counter misleading shorthand claims about vaccines (or anything else). The convo can be exhausting but it's important to engage.

Now here's one of the most interesting psychedelic narratives I've read, from @SohrabAhmari in Compact. compactmag.com/article/the-cr…
Example of the minimalist approach that will be popular in wake of FDA MDMA decision. Single-dose psilocybin "with psychological support." sciencedirect.com/science/articl… What does "support" actually entail? Talk therapy before or after? Quiet trip-sitting? etc. Doesn't say.
"The silica rule is 30 years overdue, and this administration has implemented it." Coal dust containing silica increases the severity of lung diseases, including cancer. Learn more in this report by grantee @EmilyRiceWVPB for @wvpublic.pulitzercenter.org/stories/will-n…
Yikes
This could be a great project but re: "It's time to... begin the precision design of mood, cognition and perception"... hope this team incorporates a dose of humility.

When a rural county screened for HIV, several people tested positive for the virus. So why did they report zero cases to the state? Our series “Public Health, Public Trust” continues w/@wvpublic, thanks to @pulitzercenter wvpublic.org/fears-of-hidde…
The news of @stevesilberman’s death is a punch to the gut. Steve was a brilliant writer and a kind, generous man, burning with curiosity and humanity. I barely knew him personally, but my sense of loss is heavy. Sending love to all his friends and loved ones.
