How do you cope, when your bow arm starts shaking? How do you prevent that from happening in the first place? It's a fascinating and in-depth read about a topic that affects nearly every violinist at some point.

Great to see our new paper "Health losses attributed to anthropogenic climate change" out in print today in @natclimate.nature.com, which builds on our landscaping project on climate-health attribution a couple of years ago, funded by @wellcometrust.bsky.social
🚨 NEW: Climate change is already causing 30,000 deaths per year - a global annual economic loss of $100-350B USD - but the true damage is probably 10x higher. Out TODAY in Nature Climate Change: the first systematic look at the science of "health impact attribution" 🔓 www.nature.com/articles/s41...

For Trump and his allies, renewable energy is akin to the new Cracker Barrel logo: something they oppose largely because it’s different and seems to be forced upon them. But unlike the logo, there’s no going back on wind and solar.

Research findings with p-values marginally less than 0.05 attract 60 to 110% higher Altmetric scores than those with p-values marginally above 0.05.

Today nearly all new car sales in Norway are electric. That’s true even in Finnmark, the northernmost region in Europe’s northernmost country.
For us who live in the city, the most immediate benefit is cleaner air.

There is no "science-wide replication crisis" because every word in that phrase carries unfounded assumptions. 🧵
1. There is no evidence that progress has generally stalled in the sciences. Also, no one has actually tried to estimate replicability across fields.
