Leuven might be the best cycling city you’ve never heard of. 37% of trips are by bike; not by accident, but by years of rethinking streets, reducing car dominance and recirculating traffic. While the large capitals attract most headlines, Leuven is another example of a small city making big moves.

A striking finding from global drought experiments: Trees show little evidence of physiological acclimation to drought. The inner hydraulic machinery stays the same. The safety margin shrinks. That’s a very different, more vulnerable picture of forest resilience. www.pnas.org/doi/10.1073/...
