Have you seen this? This recent study of mode share (the % share of transportation trips that are 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

J'ai écris ce texte parce que la génétique s'invite partout dans les débats sur l'identité et les revendications des peuples.
Et loin d'apporter aux luttes, pour les natifs d'Amérique comme pour les palestiniens, le risque est qu'elles soient sabotées.

AI is not a peer, so it can’t do peer review
If we still believe that science is a vocation grounded in argument, curiosity and care, we can’t delegate judgement to machines, says Akhil Bhardwaj

People say we can't compare this to the Third Reich because of the atrocities but we only found out about the atrocities after the fact when it was all said and done and we're not done with this yet so I am sure the worst stomach churning shit has yet to be revealed.

This is an important point in my view: with regard to the US pressure, we are in a situation in which our options are all pretty bad. That’s the consequence of decades of close cooperation - any efforts to decouple and/or use existing links to apply pressure also hurt us. We still may have to do so.

« Environmental Health Perspectives », née en 1972, avait cessé toute activité sur décision du gouvernement américain, et ses riches archives avaient disparu. Une société savante la reprend.
