Toolkit for folks in the US from @sse-evolution.bsky.social docs.google.com/document/d/1... Below, some points I found useful 1/4

Being a field biologist means embracing uncertainty, rolling with the punches, and keeping up a positive demeanor. That's why field biologists are so fun!! Cheers to y'all <3 🐸🌿🧪

🚨🚨 Friday night news drop from National Science Foundation!! 🧪 NSF just released its detailed budget request for next year: nsf-gov-resources.nsf.gov/files/00-NSF... We knew it was going to be bad...and it lives up. Guts direct NSF support for a **quarter million people** 🧵 on some highlights...

"It’s a remarkable quarter-century arc for an infotech company to go from revolutionizing search by using PageRank as a way of prioritizing results from influential and trusted sites, to grabbing any old random bullshit from the web and offering that up to its users in the guise of an AI Overview."

Very pleased that our online course about how to learn and thrive in an online world (thebullshitmachines.com) is mentioned in @johnthornhill.bsky.social's latest Financial Times piece.

It's great to see research on this is growing. I wrote about a case study in Indigenous persistence from California a few years ago. @lmpanich.bsky.social and others have shown local communities outlasted the arrival of Spanish missions: archaeology.org/issues/may-j...

Hello Quito! We are here to film our field sites to make a virtual field trip for Ecuadorian and US students to learn more about fieldwork and scientific collection in the classroom 🐸🧪
