New paper in PNAS!🎉 doi.org/10.1073/pnas...

Is herd immunity to infectious diseases effective when induced by natural infection? Earlier studies have suggested that population heterogeneity makes disease-induced herd immunity more effective than previously thought. Our work challenges this notion.

Is Bluesky a bubble?

We collected all 1B+ posts since Dec'24.

13% of content is political.

We found high polarization, but also strong imbalance: on most topics, the opposing stance made up just 1–2% of users.

Strongest split: Gaza, Ukraine, Musk & Trump

We're organizing a NetSci'25 satellite workshop on Directed Acyclic Graphs — if you're working on, e.g., citation graphs, pedigrees, causality, temporal-network event graphs, network representations of spacetime, or any other areas where DAGs play a role, please contribute! www.dagshop.xyz

In our new preprint, we study the herd immunity effect against infectious diseases induced by natural infection (i.e. immunity is gained after exposure to the disease). arxiv.org/abs/2307.04700
