Our new paper in @natureportfolio.nature.com. Psychedelics don’t simply disorder the brain. We found hidden, context-sensitive organisation beneath the apparent chaos -- strongest in people reporting more positive, profound experiences and a reduced sense of separation from the world. 🧵👇

Grateful to be involved in this important work. Props to Manesh Girn and Danilo Bzdok for leading! Hoping that folks read carefully and critically: notably, substantial between-drug differences challenge the primacy of "THE" psychedelic experience.

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.

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.

bullying smaller or less capable people (countries) is not a sign of strength. generosity and support is not weakness. having people’s backs is not equivalent to being taken advantage of. we were stronger when we believed in the value of our own moral imperative, and when we acted accordingly.

It was an honor to sign the guest book in the home of Anne Frank. I was here as a younger man and thought about her life as a dark chapter of history. Today, I can’t help but think of her story as one of caution. Our world is fragile, and it’s incumbent on us not to break it.

when was the last time there was a mass string of layoffs in the country like this? it sounds like we are just getting started, too. these abrupt layoffs alone will hurt the economy before we get to the downstream effects on other services and businesses

Don’t lose hope. Remember, Watergate took over two years to fully unravel from the initial break-in to Nixon’s resignation. Just like then and now, Americans are losing faith in their government. We are documenting every illegal action and will hold this administration and Elon Musk accountable.

All joking aside, the path we're headed down is widespread civil conflict. Official corruption is generally more of an accelerant than the curtailment of rights, though they often go hand-in-hand, as we're seeing.

The NIH overhead cut doesn't just hurt universities. It's deadly to the US economy. The US is a world leader in tech due to the ecosystem that NIH and NSF propel. It drives innovation for tech transfer, creates a highly-skilled sci/tech workforce, and fosters academic/industry crossfertilization.
