The Pandan family (#Pandanaceae) is widespread in tropical Africa & Asia. They are diverse in habit: climbers & epiphytes, shrubs, trees, emergent aquatics & mangroves. Poorly studied. Herbarium collections are often inadequate. #TropicalBotany 📷: Pandanus polycephalus #Botany #PlantScience 🌾🧪

🧪 Excellent code of ethics for a scientific society.

When you’re watching some of the more ridiculous Shark Week shows, consider the code of professional ethics for the American Elasmobranch Society, the world’s oldest and largest professional society for scientists studying sharks and rays.

This is so important. I stress to new grad students that they are no longer learning facts. They are now learning *how* we know facts to be true (controls, etc) and generating new facts. ‼️Critical thinking and discovery are exactly what AI cannot do. ‼️

I mean, the point of a PhD (or any degree, or ideally any level of education ever) is to teach you how to see something NEW and UNUSUAL in what you’ve read. That’s literally the opposite of the pattern-matching algo that is AI. It’s why almost none can even get simple math q’s right. Just … no.

Despite popular myths, there is no stereotypical scientist. Each person brings their own history, personality, interests and approach to their work. I love interviews with scientists that reveal their back story and how they view their life and work 1/2 🧪

Part of a good thread that illustrates why I don’t hang out on Twitter/X anymore

There was an even bigger difference in the comments received. All on Threads and all but one here were positive, constructive, or neutral (one person was just being a jerk, not a troll). Only 18% on X were positive or neutral. The rest were negative, many highly so.
