Ok folks, now more than ever, we need to Be Kind and do Good Science.
This means digging in, producing the evidence, communicating clearly and sincerely, celebrating our collective curiosity, and being mindful of the spaces we are and can be in.

Great to see this one out - one of the original questions on this #NSF BII journey - are wildlife more or less 'zoonotic' as they become more endangered? Read on below...

NEW! 🦠🦧 We revisited a perplexing paradox: do wildlife really pose less of a risk to human health as they become more endangered? Turns out, it's sampling bias all the way down: conservation risks correlate with disease surveillance blindspots. 🔓 esajournals.onlinelibrary.wiley.com/doi/full/10....
Viral diversity and zoonotic risk in endangered species
A growing body of evidence links zoonotic disease risk, including pandemic threats, to biodiversity loss and other upstream anthropogenic impacts on ecosystem health. However, there is little current...

Twitter accounts are based in Russia. BlueSky accounts are based in homes with, frankly, too many books, plants, obsolete cables, and pieces of rustic pottery, that could do with a bit of a tidying up, to be honest.

While this is a bit of a harsh way to put it, it is not a false scare. The importance of resource allocation to health, to health infrastructure, to basic staffing, is misunderstood by the people with the resources.

In a rapidly warming world, heat waves will become mass mortality events. If 2003 European heat wave were to recur with 1.5 °C of warming (we're close to that today), this study predicts 17,800 excess deaths across Europe in *one week.* With 3 C of warming, the toll rises to 32,000.
