super cool study found human artifacts in Bearded vulture nests, incl. "weaponry like a crossbow bolt and wooden lance, decorated sheep leather, and parts of a slingshot....a shoe made from twigs and grass is ~675-years-old." link to paper: doi.org/10.1002/ecy..... www.popsci.com/environment/... 🧪🌍🦉
Multi-generational vulture nests hold 700 years of human artifacts
Crossbow bolts, sandals, slingshots, and more.

Actually my favorite bird etymology is that in 1400s England they gave human nicknames to birds (Jenny Wren, Tom Tit) but some of them stuck. Jack Daw became Jackdaw, Maggie Pie became Magpie. With Robin Redbreast they just dropped the original name of the bird entirely.

🐇 Very happy to announce our new paper in #ProcB on rabbit #domestication and feralization and what that does to the skulls of these animals. That's #evolution going on in (almost) real time.

New OA paper out! This doesn't happen very often anymore but I am very happy about this one! In 2023, Jolantha Eschrig (@jolantha.bsky.social) came to St.Gallen to create what is now the first complete inventory of meteorite specimens in Switzerlands public collections. Thread! ☄️🪐🔭 (1/6)

Our new paper, based on data from 1,705 studies, shows that pesticides are toxic to organisms they are not intended to harm, including fungi, microbes, plants, insects, & vertebrates such as ourselves. Questions the wisdom of applying over 3 million tonnes of them every year...

We expect that some 50 Auschwitz Survivors will come to the Memorial for the 80th anniversary of the liberation.

The eyes and ears of the world should rest upon them.

We must safeguard their voices from silence, distortion, or being overshadowed.

And done. I feel people would appreciate fishes more if they could see them face to face more often. Such beautiful creatures.

From top to bottom: European perch (Perca fluviatilis), dace (Leuciscus leuciscus), northern pike (Esox lucius), roach (Rutilus rutilus) and gudgeon (Gobio gobio). #Sciart

Under the feet of the dinosaurs, our own ancestors lived... surprisingly slowly.

One of the work highlights of last year: a press release illustration I painted for @elsa-panciroli.bsky.social for her and colleague's paper on a fascinating fossil find.

That these kinds of experiences can form core memories absolutely warms my heart as a museum scientist and educator. Museums are an essential public good!
A core memory for me is finding my first fossil in a sandbox at the Nebraska State Museum and learning about sea urchins.

Museum educators: sometimes the 3-4 year-old really does keep their free fossil forever and advances beyond junior paleontologist. Thanks for all you do. #fossilfriday
