Princeton finally handed off some advance copies for the 2nd Edition of my wasp book, and they look phenomenal! Thank you everyone for your exceptional patience! Go order it right now!! press.princeton.edu/books/paperb...
A photo of me (a white woman with long brownish hair wearing glasses and a dark blue shirt) holding an advance copy of my book "The Social Wasps of North America, Central America, and the Caribbean: Second Edition" in front of an old wooden railing and some lush sassafras leaves. There is a big illustration of a bald-faced hornet on the cover. 

This photo is slightly misleading, since it was taken by my mom a year ago in 2025, immediately before we noticed the major printing errors in the plate series that required us to completely redo the printing from scratch. My joy is nonetheless real, and I feel justified in using this photo since I never posted it the first time around. It's all good now!

Using a simple delta rule (Rescorla-Wagner) tweaked so that the associative strength of the common elements is weighted by its exposure-dependent activation we can simulate our results, showing latent inhibition, and its reversal:

We just published the first study showing that a bird-of-prey goes through an ontogenetic window of exploratory play. Young goshawks look like young cheetahs when tossing pine cones into the air, chasing after them. Just published in Animal Behaviour: www.sciencedirect.com/science/arti... 1/4

Chater & Christiansen asked in BBS "How has human culture become so complex?" & answered that social tinkering is a key process. In our reply, we argue that complementary minimal principles can explain how simple mechanisms generate complex cultural organization. doi.org/10.1017/S014...

This is a good time for UK institutions to start rethinking their genAI use in education. It always is! We must decide what kind of instruction we want our students to receive: one that quickly dumps them into an illusory, ephemeral work sphere, or one that gives them the knowledge they'll need.

Easily one of the most spectacular natural events I’ve ever seen: an endless river of Sooty Shearwaters along the Washington coast. These ocean-dwelling birds migrate 40,000 miles each year, foraging in massive flocks. This went nonstop for at least an hour. Best estimate is 100,000 birds.
