In just about a week, the season's first NetSci Colloquium will happen. And we're starting with a bang . . . with none other than Iain Couzin talking about Collective Behavior in Animal Groups. September 24, 10 AM ET. Register here to get a Zoom link: iu.zoom.us/webinar/regi...

Paper alert! See the new pre-print up on arXiv by Tim Mauch (@timmauch.bsky.social) and Thilo Gross (@thilogross.bsky.social) on opinion formation: arxiv.org/abs/2508.15377 The paper discusses the very nice results of Tim's master thesis, so let's get into the details, shall we? 1/5

They have to destroy scientific research to eliminate the point at which civilians from every warzone connect and recognize themselves. How can you build a quantum computing lab without Iranians? Or an ML theory lab without Israelis? Better to let progress die than to allow that they might meet.

The rot is spreading ...

Our new article in Chaos. One of my favorite articles so far. Connecting different disciplines and building on recent breakthroughs in ancient fields (Linear Algebra!). link.growkudos.com/1ebwrn9qkn4 doi.org/10.1063/5.02...

insane moment in world history right here

The dynamics of microbial cooperation... Cheap metabolites make for shaky friendships; but pricier ones can keep the peace... 🦠 Thanks @janamassing.bsky.social for leading the charge! And great working again w/ @akfbio.bsky.social & @thilogross.bsky.social

Meet our group members! Time to hear about the wonderful @laurabarthm.bsky.social: "Hi, I’m Laura! I’m a physicist by training and a PostDoc researcher working with physics-informed neural networks to enhance the interpretability of ecological models and improve forecasting.

I finally got around to edit the second part of the video on the walk (it mostly explains the math of how it was made). youtu.be/g52Lcr3rRHc (The first part is here: youtu.be/Mnaf2Y_ydq8 )

Everybody should read this ...

Meet our group members! Today let's hear from the wonderful @srilenak.bsky.social: "Hi, I’m Srilena, a HIPP postdoc in the Biodiversity Theory group. I have a background in Applied Mathematics with a research focus on theoretical ecology. My research approach combines mathematical modeling, ...

Here is a lesser know background regarding the Trump Tarifs. You might have heard that so far they wiped out 6 trillion dollars (!!). But is this money really gone or is it just elsewhere? Most of it is currently being burned, and it is importnat to understand why ... [a short tread]

Meet our group members! More postdocs to come. Today is the great Kate P. Maia: “Hello, I am Kate. I am an ecologist with a background on applying network theory to study mainly terrestrial mutualisms, such as the interactions between plants and pollinators.

This picture summarizes very much what Ole does in our lab...

About a week left to apply to join the Amsterdam Center for Dynamics and Computation as a postdoc!

Meet our group members! We continue with our PhD candidates. Today @ranashj.bsky.social: "Hi, I'm Rana! I studied physics for both my bachelor's and master's degree. My favorite subjects were statistical physics and quantum mechanics. In my thesis I studied the evolution of social networks ...

I have just (with a heavy heart) declined an invitation to the Santa Fe institute. Politics sucks.

Ashkaan describes it very well. Really excited about this paper. I think it enables a new way of studying ecological systems.

French researcher, going to a conference in Houston, was forbidden entry to US; his work and personal electronics were both confiscated. Why? Because a “random search” of his cell phone revealed a negative personal opinion on Trump and the Trump administration. www.lemonde.fr/internationa...

I couldn't put it better, so I share this wonderful post. New paper out on arXiv! It's a collaborative work of our group members @mhab.bsky.social, @thilogross.bsky.social as well as our great colleagues @akfbio.bsky.social and @jdyeakel.bsky.social:

Everything this fucking guy does benefits Putin.

There are days in life that shake you. I’m shattered 💔 to share that I just found out that the US Government terminated my 2024 NIH Director’s Early Independence Award (~$2 million), threatening my long-promised assistant professor job at Columbia University & academic career... 1/🧵

Two things I like about my commute in Oldenburg: Cormorands and fog. (also mirror images of C)

1. Today in Santa Barbara I saw an extraordinary abstract art piece—or so it seemed—from Hank Willis Thomas. As we speak, Trump seeks to erase large swaths of our history, attempting to erase the most shameful parts of our history, and paint over the triumphs and sacrifices of people of color.

Dear American friends, you are so lucky that your democracy is tested by people who aren't skilful autocrats. Imagine someone more clever had tried that. Imagine somebody competent trying that. Now is the time to make plans to rebuild better.

I don’t understand why this is not seen in government circles as the crisis it is. I’ve seen full-scale banner headlines over job losses a fraction of this size in industries worth a lot less to the UK economy. Surely government has to step up at some point?

This CDC "survey" getting sent to grantees is wild yall. This is some serious "Kiss my Ring" level bullshit.

Really excited about this:

Meet our group members! Starting off with our research assistant and newest member @timmauch.bsky.social: Hi, I'm Tim, I studied environmental modeling in my master's degree. I'm interested in the intersection of social and complexity sciences - particularly in relation to social media.

Great talk about what complexity science is and can be, by @thilogross.bsky.social in a packed room @comunelab.bsky.social in Padua. A week full of #ComplexNetworks #ComplexSystems #ComplexityThoughts

Sweden: "Not implementing a mandatory lockdown was blamed for the higher mortality seen in Sweden. In a modeling study... researchers found that the infection rates could have been reduced by 75% and mortality could have been reduced by 25%" kevinmd.com/2025/01/swed...

Question of the month: You have an Erdős-Rényi random graph with a mean degree of 4. Of course it has also a mean excess degree of 4, but then you decide to remove all nodes of degree 0 and 1. Do you expect the mean excess degree to go up or down? (Solution in the NetSci newsletter)
