#OnThisDay in 1859, Charles Darwin's landmark book 'On the Origin of Species' was first published. The work is one of the foundations of evolutionary biology, and one of the most important scientific works of the 19th century. #HistoryOfScience

Wonderful remembrance of the great Philippe Taquet by my friend Didier Dutheil. Sad news indeed.
Very proud to have been part of the team that honored him by naming a dinosaur species after him—and a most bizarre one at that (which, as it turns out, was found by Didier).

Destiné à reprendre l’industrie textile familiale, cet esprit libre a préféré la vie de chercheur d’os, découvrant plusieurs espèces d’animaux disparus, tout en menant une carrière institutionnelle de premier plan. Il s’est éteint le 16 novembre, à 85 ans.

My advice for #2025SVP would be aimed not to students, who are excellent in our society and I am sure will do great but on senior academics. During Q&A, please resist the urge to grandstand or grill. Be polite, constructive, and supportive. That’s how we build a stronger, kinder community. #SVP2025
Many of our student attendees will be giving their first talk or poster this meeting! What advice you give them to help make it the best experience possible?

This is excellent advice for all first time presenters … also, the quality of your talk will not impact your future career - that comes down to your CV & skills overall, not your ability to perform on the platform. So, if you slip up a bit don’t sweat it - most of the audience won’t realise anyway 🤷🏻♂️
The best advice I received back when I gave my first presentation was, "This is your study and you know this subject better than anyone else who might be listening. Relax." It helped. #2025SVP
