I analysed the modal share of nearly 400 European cities, comparing those with a metro, only a tram, and without any rail system. Large cities with a metro have roughly half the car share of cities served only by a tram. www.nature.com/articles/s44... Data: CitiesMoving.com

How can car traffic in cities be reduced? New research by CSH's @rafaelprietocuriel.bsky.social shows that while metros are effective in reducing car traffic, a study of nearly 400 European cities finds no evidence that trams have the same effect: csh.ac.at/news/metros-...

🌐 How can we address organized crime? Last week, we hosted a #workshop, organized by @rafaelprietocuriel.bsky.social, exploring the complexity of violence – including cartels and their recruitment practices, social media dynamics, crypto crimes, and law enforcement strategies

This week, we had the honor of welcoming @sergioaguayo.bsky.social and his team from Colmex to @csh.ac.at. Throughout the week, we discussed science, violence, migration, politics and more. This Wednesday, his column in Reforma was dedicated to complexity and violence. ⚗️🥼🔬

Congratulations to Dr. Rafael Prieto-Curiel, winner of the Junior Scientific Award 2025, for his contributions to complex systems research through innovative mathematical modelling of social phenomena🎉

Now at the criminal complexity satellite, @rafaelprietocuriel.bsky.social just gave a wonderful talk showing his progress when modeling organized crime recruitment by Mexican cartels. His results show that current Mexican and US policies are not enough to effectively reduce recruitment. #CCS2025

We are excited to invite you to Criminal Complexity, our Satellite Event at #CCS2025 in Siena, focusing on Crime, Violence, and Complexity Science! Join us for a series of talks that explore the intersection of criminal phenomena and complex systems. criminalcomplexity.weebly.com/programme.html

While in Vienna, CSH resident journalist Will Grimond was fascinated to learn about grätzloase--neighbourhood oasis made by and for residents to enjoy shared urban life. And he wrote a story about it for @theguardian.com (featuring @rafaelprietocuriel.bsky.social and @csh.ac.at): shorturl.at/gC6Ch

🚶🚌🚗 Where you live in a city shapes how you commute. @rafaelprietocuriel.bsky.social (CSH) & Filipe Barroso (Universidade de Aveiro) analyzed Lisbon & Porto and found: car use rises ~1% every 2 km from downtown, reaching 75%+ in outer neighborhoods. Over the decade, car trips increased nationwide.

🚔 #Crime has a rhythm — can we decode its beat? In a new study co-authored by CSH's @rafaelprietocuriel.bsky.social, 12 years of detailed crime data reveal relatively stable temporal “heartbeats” for different crime types over time. journals.sagepub.com/doi/10.1177/...

No, it's not the case that only China is responsible for the large decline in extreme poverty over the past decades. We wrote about it recently: ourworldindata.org/data-insights/was-the-global-decline-of-extreme-poverty-only-due-to-china

Very privileged to have @rafaelprietocuriel.bsky.social teaching a 5-hour course on Cities as Complex Systems! 🏙️🌳 More info: www.crm.cat/summer-schoo...

Migration is shaping the future of our societies — but how can research help shape migration policy? Last week, the #HumanMigration research group led by @rafaelprietocuriel.bsky.social hosted a three-part event series at the Complexity Science Hub to explore this pressing question.

This is interesting — a recent study of mode share (the % share of transportation trips by car, transit, walking, biking etc) relative to city size and income levels in almost 800 cities in 61 countries. Interesting results. HT @davidzipper.bsky.social www.sciencedirect.com/science/arti...

When streets are safe for walking & cycling, people spend more time outdoors, supporting local businesses & keeping city centres alive. 👍Good for business 👍Great for communities 👍Essential for safer & healthier cities 🔗 bit.ly/4jPzXsa #RoadSafety #StreetsForLife

Urban complexity science has changed how we think about cities—now it's time to rethink how we plan them. At @csh.ac.at, @rafaelprietocuriel.bsky.social & @diegorybski.bsky.social are leading a workshop to turn insights into action, with experts tackling policy, planning, and the future of #cities.

🚨 Last days to submit!!! 👇

The media plays a key role in bringing science into society—and sparking real change. That’s why we’re thrilled to see a full-page feature in El Universal on Rafael Prieto-Curiel’s research into the dynamics of Mexican cartels. Congrats, @rafaelprietocuriel.bsky.social—well deserved! 👏

La industria automotriz ha creado la ilusión de que reemplazar el combustible de los autos los hará sustentables. Pero su fabricación o los 3,000,000,000 de neumáticos que se producen son parte esencial del problema. Mi charla en @institutocervantes.bsky.social www.culturalatina.at/es/cronica/i...
