I enjoyed the reminder by @brilliantmaps how exciting the age of railways actually must’ve been. From 1837-1875 the network in France just exploded. Imagine seeing the world open up to you so rapidly after being relatively stuck in your region for so long. Source: buff.ly/RgyNhfd

A great post from @scholarlykitchen.bsky.social exploring the link between #openscience and research integrity. The authors highlight a recent PLOS Open Science Indicators (OSI) dataset as a tool used to help assess this relationship. See the OSI dataset: plos.io/3ZFdjYL Read the findings ⬇️

Before looking at this graphic, see if you can guess the top 5 or top 10 cities with the most skyscrapers. The graphic defines skyscrapers as buildings above 150 meters (492 feet or 69 Shaquille O'Neals for our friends from the US).

In cellular automata, simple rules create elaborate structures. Now researchers are working backward — starting with the result to learn the rules behind it. @georgemusser.com, SFI’s 2025 Journalism Fellow, explores how this could reshape computation and self-organization in Quanta:

Major European cities at the same scale. I to Melbourne (Australia) 18 years ago from Berlin. You can squeeze Berlin around seven times into Melbourne. Density matters. In a low density beast like Melbourne residents pay for much more infrastructure per head. Expensive exercise. HT @xruiztru

Looks more complicated than it is. In our recent study journals.plos.org/plosone/arti... we search for an optimum city size, minimizing both urban carbon emissions and urban heat island (constraint: fundamental allometry). It turns out that given the known UHI parameters such optimum does not exist.
