ICE is no longer an immigration agency. It is a paramilitary force, backed by a parallel prison system, answerable to the president alone. What’s happening in the U.S. isn’t a deviation—it’s an infrastructure. And it won’t end with Trump. civiceconomist.substack.com/p/ice-trumps...

Reconstructing the early spatial spread of pandemic respiratory viruses in the United States www.pnas.org/doi/10.1073/...

Excited to share a new study published in PNAS! @pnas.org We reconstructed the early, cryptic spatial spread of 2009 H1N1 influenza and SARS-CoV-2 across US metropolitan areas. Link👉https://www.pnas.org/doi/10.1073/pnas.2518051123 #PandemicPreparedness #InfectiousDisease #HumanMobility

If accurate, this raises the question "who is governing Venezuela right now, and tomorrow?" (The answer isn't "Delta Force" or "SEAL Team 6," that's not what they do.) While nearly every state has a presidential line of succession, that may not indicate where power actually lies in coming days.

For the first time in my career, I can’t tell people to trust what the CDC website says. And that is an incredibly sad and devastating place for this country to be.

Trump just continually shooting our country in the face. This unwarranted (and likely illegal) destruction of Goddard is madness. It jeopardizes the next several decades of space exploration.

Proud of this work published in @pnasnexus.org! Thanks to @marcotonin.bsky.social and Bruno Lepri for a great collaboration!

Who people spend time with in physical space is more predictive of voting behavior than who they connect with online, according to a study. The study uses real-world colocation data derived from the Facebook app’s location services feature. In PNAS Nexus: https://ow.ly/PBTe50XhFcC

Un dato drammatico che resta quasi del tutto ignorato.

Solo il 32% dei 25-34enni italiani ha una laurea contro il 44% della media dell'Unione Europea. L'Italia ha il secondo peggior dato dopo quello della Romania. Siamo anche uno dei paesi con più giovani che si fermano alla terza media, quasi uno su cinque.

I am deeply honored to be awarded the Lagrange Prize 🏆, the premier award in the field of Complex Systems. I'd like to share this moment with all my current and past students, research team members, and collaborators over the years. Thank you CRT Foundation & @isi.it for this honor

This morning my ChatGPT quota was inexplicably exhausted. It took a while but I pieced it together. Voice mode somehow got activated when I went to bed. The bot then engaged in a 10 hour conversation with my snoring dog, answering questions the pup wasn’t asking and praising him for his insight.

Epidemic amplification by correlated superspreading arxiv.org/abs/2509.15338

Can large language models stand in for human participants? Many social scientists seem to think so, and are already using "silicon samples" in research. One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want. THREAD 🧵
