I’m going to be clear. In my opinion, none of these people can be trusted. Prasad and Hoeg made their careers out of an agenda to take down COVID19 vaccines.
It is so incredibly dangerous to have these people at the FDA. They are a threat to the entire U.S. vaccination program.

Honestly, when will unis and other research orgs collectively say enough is enough, and invoice them for all our unpaid labour that drives publishers MASSIVE profits?

If we don't privatise everything that the people own and award contracts to the company that donates the most to a political party then where do we expect politicians to make money from when their terms end

Day 132 is Thanksgiving (in the US) (and my birthday)! Thankful for all of you and all the pets! Here are two weirdos who are thankful for each other, even if they won’t admit it. #UglyDogs

Out now: Favila, Capece Marsico et al. 2025, Nature Communications: Using longitudinal deep-brain imaging, we report that amygdala interneurons exhibit complex and heterogeneous plasticity during associative learning, at both the single-cell and population level.

Heterogeneous plasticity of amygdala interneurons in associative learning and extinction - Nature Communications
In this study, the authors uncover how diverse inhibitory interneurons in the amygdala flexibly contribute to fear and safety learning, revealing a key role for inhibition in emotional memory and adap...

Russian asset Ron Johnson says there’s no money to give Americans $2K inflation checks. But there is money for a despot’s $250M ballroom and enough to give $40B to Argentina’s dictator.
I’ll always remember Ron paying Putin a visit in Moscow on July 4th weekend in 2018.

New lab paper drop, this one has been a long time coming! Driven by Rob Aukema (now a postdoc with Kerry Ressler) this paper in Science Advances answered the lingering question of what role the amygdala plays in stress-induced neuroendocrine responses.

I tried an even harder example on Gemini Pro image generation and this is quite scary/amazing. I asked for a microscopy image of around 20 HeLa cells, GFP tagged 20% nuclear, 10% membrane, +1 nuclear staining, + overlap. Image below and prompt in the following post.

Excellent analysis of the COVID response in the UK & Europe.
Some questionable appraisal of Sweden, without considering comparisons with NZ, Australia - or indeed Finland, Denmark, & Norway.
Many countries minimized COVID deaths AND minimized lockdown, by reducing infections.

We are living in the stupidest period of US history and this is saying something.
GOP Sen. Ron Johnson is crowing about Robert Kennedy Jr.’s CDC pushing debunked vaccine misinformation.
“Time to apologize to Dr. Andrew Wakefield and all the others who were maligned and vilified for simply asking the right questions,” he says.
Wakefield’s paper was *fraudulent.*

“This is how the wellness influencer industry works,” Hotez said. “It’s not enough to push the snake oil. You have to discredit mainstream biomedical science and portray scientists as public enemies or cartoon villains, and that's what Kennedy’s seeking to do.”
