Excited to highlight a new paper from my graduate student Sergio Bernal Garcia who, together withLuke Hammond, developed RESPAN, a new deep-learning pipeline automating the segmentation of neuronal morphology and dendritic spines from fluorescent microscopy images: www.cell.com/cell-reports...

✨ Post-doc opportunity in axon biology, funded by #ATIP-Avenir! 👀 We are looking for an enthusiastic post-doc to join our team at @ibdm.bsky.social to explore translation dynamics in axon regrowth, using live imaging approaches. Apply at: emploi.cnrs.fr/Offres/CDD/U... Thank you for sharing! 👋 🙏

Simpering cowards one and all. This is almost unbearable to watch.

fascinating results👇

I enjoyed this. And what an infectious laugh. ❤️ "Reporter left speechless after witnessing Japan's new $70 million Maglev train in action at 310 mph"

Modern-Day Oracles or Bullshit Machines? Jevin West (@jevinwest.bsky.social) and I have spent the last eight months developing the course on large language models (LLMs) that we think every college freshman needs to take. thebullshitmachines.com

In 25 years, every business school in the country will be doing case studies about how a long defunct company known as “Google” once had an unbeatable lock on online information retrieval and then started doing shit like this.

Watch this video about the new Vera Rubin telescope. Truly remarkable scientific and engineering achievement, so much to learn about our universe! I In these troubled times, it's so refreshing and stimulating to realize how transformative science and human ingenuity can be 👇

New, from me: The Times published a piece accusing a man born in Africa as claiming to be African-American in a failed college admission. They viewed this story to be newsworthy enough to grant anonymity to a eugenicist working with hacked personal data. donmoynihan.substack.com/p/whos-afrai...

Elon Musk casually, and illegally, dismantled USAID. According to a new study in the Lancet, that action will lead to *14 million* premature deaths between 2025 and 2030. Again: Elon Musk is directly responsible for 14 million coming deaths. 4.5 million will be children.

Dissolving ACIP is an absolute mistake. We need accurate information—not fringe theories—guiding government recommendations on which vaccines to give which people.

My message to Trump’s NIH Director? No one in America wants us to do LESS cancer research. No one is asking Trump to make it harder to cure Alzheimer's disease. Yet Trump is cutting all of this NOW and demanding an $18 BILLION cut to NIH next year. Not on my watch.

Trump sends 5,000 military to invade & occupy LA, and NYT headline is literal false-equivalency he-said-she-said.

RFK Jr.‘s extreme anti-vax views — and his related conflicts of interest — were a huge problem during his confirmation process. So he promised not to change the vaccine advisory panel. Today, he fired every single expert on that panel. It's a public health disaster.

Vaccines are rigorously tested, they are effective, and they save lives. More than 150 million lives have been saved in the past 50 years thanks to vaccines! But you may be worried about what's in them? So, let’s break it down ⬇

Postdoc opportunity in the heart of Europe! Check out the flyer below. Join our team on an international project with Anthony Holtmaat exploring synaptic plasticity and specificity in cortical and thalamocortical circuits.

🚨URGENT RESPONSE CALL🚨 You’ve seen the bad news. Now it’s time for us to flood the zone. Over 400 NSF grants — gone. Trump’s cronies are cutting science funding and betting we won’t notice. But we’re not powerless. We’ve got 24 hours to make noise. Here’s how 🧵(1/3) ➡️

excellent opportunity!! 👇

It's hard to see what is happening unless you pull back the lens, read @ruthbenghiat.bsky.social and others on autocrats and centers of knowledge and expertise. Once you recognize it, a chill should go down your spine. www.thenation.com/article/soci...

Published an op-ed for @cnn.com: “Nobel laureate: I owe America my success. Today, its scientific future is in danger.” A personal reflection on what’s at stake as science funding gets slashed. I’d be grateful if you could amplify both in and beyond the science world. www.cnn.com/2025/04/09/h...

The current figure I'm seeing is that as many as 3.3 million Americans protested today. #HandsOff #Resist

I've already had two federal grants terminated and face a 33% pay cut due to future terminations. It's painful, but not as painful as the conversations I'm having every day with brilliant trainees in graduate school and postdoctoral positions who see little future for themselves in US science.

We were there!! massive crowd for the #HandsOff rally in NYC from Bryant Park to MSG.

Trainees, graduate students, postdocs or PIs, consider registering for this fabulous practical Brain Prize Course on 'Advanced Techniques for Synapse Biology' this summer (June 23-July) in Bordeaux, France. Amazing lineup and instructors. Deadline is March 31st 👇 cajal-training.org/on-site/syna...

1. For the past thirty years I've had the best job in the world. 
I've had the opportunity to follow my curiosity; explore the workings of nature and society; mentor students and junior colleagues in the same process; and teach generations of students about it all.

I’m struck by how close we’re getting to finally curing some of the world’s worst diseases—sickle cell, Alzheimers, pancreatic cancer, etc.—at the same time that the world’s worst people are destroying medical research and care around the world.

An unnecessary and self-mutilating attack on scientific research. Making America Sicker and Weaker Again

I confirm, one of my own MD-PhD graduate student, who received a perfect 1.0 impact score, just got her F30 award canceled. Enraging.

the attack of this administration against science continues, this will have such lasting and devastating consequences on the future of this country...

After Watergate, Congress created a system to audit the executive branch and protect the rights of federal workers. Those offices became known as watchdogs. Now, for the first time in 44 years, President Trump has fired these officials en masse. https://cbsn.ws/4bEkPdC

As a former Fulbright Scholar (in Chile), I personally understand how terrifying this is. U.S. citizens around the world & foreign nationals in the U.S. — all Fulbright Scholars — have now had their incomes eliminated & are stranded. DOGE is an illegal, criminal operation that must be shut down.

beautiful day to support science in NYC 💪🏻 #standupforscience
