Each year, I teach "Evolution of Plant Form and Function" to undergraduates - I've struggled to find good synthetic out-of-class materials - until recently. This is such a superb overview of the functional and physiological overview of land plant evolution www.youtube.com/watch?v=ZSch... 🧪🌾🌐 #botany

I have a memory of him on debut in 1988 absolutely lining up Winston Benjamin w a pull shot so hard it came back to the square off the boards, thinking YESS!

Yeah there's certain people you associate w an era - Eng were so shit so often then, seeing someone take on proper quick stuff like this was amazing

Really sad about this. Such an amazing player to watch - hit the ball as hard as anyone I've ever seen

JD Vance claims that diversity weakens unions, as people end up distrusting each other and not organizing.

Let me tell you two menswear stories related to this claim. 🧵
New study from Ty Loft’s PhD thesis. We used an energetic approach to quantify, acr sub-Saharan Africa, how mammal- and bird-mediated ecosystem functions have changed. We found that overall trophic energy flows have decreased by more than one-third, but this change varies across biomes and land uses
