Today, Trump declared war on his own citizens, calling for U.S. cities to be used as “training grounds” for troops to confront what he called an “invasion from within.” Americans are a proud people, and no one (foreign or domestic) will threaten our home.

1/ New consensus statement just dropped on the potential for psilocybin in clinical care, from the Task Group on Psychedelics and Related Compounds of the US National Network of Depression Centers

The message? Lots of promise, but real risks if we rush. 🧵

Dear god let this man cook.

Pritzker: It’s time for us to be done with optimism about their motives. Time to stop wondering if you can trust the nuclear codes to people who don’t know how to organize a group chat. It’s time to stop ignoring the hypocrisy in wearing a big gold cross while announcing the defunding of children’s cancer research… Autistic kids and adults who are loving contributors to our society don’t deserve to be stigmatized by a weird nepo baby who once stashed a dead bear in his car. Our military service members don’t deserve to be told by a washed-up Fox TV commentator, who drank too much before being appointed Secretary of Defense, that they can’t serve their country simply because they are Black, gay, or a woman.

I said my main goal of this trip was to meet with Kilmar. Tonight I had that chance. I have called his wife, Jennifer, to pass along his message of love. I look forward to providing a full update upon my return.

I'm a member of the NIMH BSC. The members who were fired are outstanding scientists, which is why they were appointed to the BSC in the first place. Their firing for unspecified reasons is unconscionable.

At least four neuroscientists received termination letters this week dismissing them from NIH advisory boards. “This is unusual and unprecedented,” says @thebalelab.bsky.social, one of the terminated board members.

To do this, when viewing your own profile there is a button with a "+" sign toward the top right-hand corner of your citation list. Clicking that button, you can "Configure article updates", then select "Don't automatically update my profile. Send me email to review and confirm updates."

First, I would go through and delete anything that a) isn't yours, b) is duplicate, and c) isn't peer-reviewed.

Second, I would make sure that your profile is set up to not automatically add things - this way, you can confirm what is real before it is added to your profile ...

Thanks @eeschenberg.bsky.social!!

For Google Scholar, I make sure to only accept real peer-reviewed articles. There are occassionally conference abstracts and/or popular press, and sometimes (depending on your name) other folks articles that may appear or be erroneously linked to your profile ...

Fred Barrett @fredbarrettphd.bsky.social · Mar 25

Thanks, Matt!!!!

Fred Barrett @fredbarrettphd.bsky.social · Mar 25

gotta celebrate all small victories - I just passed 10k citations on google scholar :) only legit peer-reviewed articles (this can be a fickle and deceptive number depending on what items make it on the list).

Keep good Google Scholar hygiene, people!

For the democrats saying “we can’t let the govt shut down” you’ve already lost. It’s not on you.

Republicans control everything, didn’t come to you for anything except your vote. Where else can you force changes? You can’t… you’re a willing participant in Republican majority
