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 Link: arxiv.org/abs/2506.03443 🔽
