Prof. Jasmina Wiemann has been selected for a prestigious Packard fellowship. This the first recognition of a paleobiologist by the Foundation!
That is 8 Packard Fellows in 6 years for Johns Hopkins University.

Imagine you could not only chemically characterize individual molecules, but also simultaneously visualize them - in their biological framework or at mineral surfaces ... my AFM UV|Vis|NIR-Raman spectroscopy lab is officially operational, and the first data exceeded expectations!

The breakthrough proof bringing mathematics closer to a grand unified theory
Nature - The Langlands programme has inspired and befuddled mathematicians for more than 50 years. A major advance has now opened up new worlds for them to explore.

I picked up the current Re-issue of 'Reimagining #Dinosaurs' in @ National Geographic - just in time for #JurassicWorldRebirth!
Our research is still as exciting as it was 4 years ago, but my lab is now proudly based @jhuartssciences.bsky.social [with co-featured Fabbri, Balanoff, & Bever labs].

1️⃣/ Fascinating new piece in @cenmag.bsky.social on the hunt for dinosaur proteins! The 2005 Schweitzer T. rex collagen reports remain contentious after 20 years. Recent Edmontosaurus data adds fuel to the debate, but I cofess I remains cautiously sceptical. #palaeoproteomics
