Our new paper is out in @jevbio.bsky.social! Body size shapes aggression as well as how strongly individuals influence their opponents and how responsive they are to social interactions. @cdegroot.bsky.social @roriwijnhorst.bsky.social @dingemanselab.bsky.social doi.org/10.1093/jeb/...
Size-mediated differences in social responsiveness (left) and social impact (right). Here, individual i is smaller, more responsive to variation in opponent body size and elicits more aggression from opponents than individual j.

A victorious Andy Burnham MP (24,937 votes), as the result of the Makerfield by-election is announced, flanked by defeated candidates Count Binface (a bloke in a vaguely sci-fi costume with a large bin for a helmet; 95 votes) and Robert Pownall (who is in a full body fox costume, holding a sign reading "Protect British Wildlife"; 18 votes). There are some other candidates there just out of shot but that's not important right now.

Happy birthday to one of greatest mathematicians of all time Emmy Noether (1882-1935), here with her eponymous theorem, the backbone of modern physics. 🐡🧪👩🏼‍🔬🧮🎢 #histsci Noether’s theorem links any symmetry of a system with a conservation law. In my portrait, I chose to depict a young Emmy in front 🧵
My linocut portrait of Emmy Noether in front of a blackboard with diagrams and equations. Noether is printed in blue. She has her hair up and wears a pin-striped buttoned shirt with puffy sleeves, bow tie, tweed skirt with belt and is shown from waist up, turned slightly away from the viewer. The blackboard is green and shows a simple form of Noether’s equations at the top. On the left are three diagrams to represent translational symmetry (a frame of reference or 3 orthogonal axes and a straight diagonal arrow to a second frame of reference); rotational symmetry (a frame of reference and curved arrow to a second rotated frame of reference); and time symmetry (two simple clocks with an arrow between them and their hands at different places). On the right are the three associated conserved quantities: momentum (a p with arrow above it); angular momentum (an L with arrow above it); and energy (E).
