I had the experience of a lifetime on Tuesday, seeing Rush in LA. Their new drummer, Anika Nilles, is off-the-charts f*king extraordinary. It seems like apostasy, but she's at least as good as Neil. @lawrensack.bsky.social was kind enough to accompany me and translate the lyrics from Canadian.

I'm very sad to say William Bond, of the University of Cape Town & Fellow of the Royal Society (@royalsociety.org ), has passed away. It is a great loss. He was an enthusiastic ecologist and a critical thinker. I learned a lot, and I still had a lot to learn from him. RIP. 😢 🧪🌎🔥🌿🌳🪴🌐 #PlantScience

Saddened to hear about the passing of Steve Long. His work had a profound impact on plant science. A true loss to the scientific community. @ripeproject.bsky.social emails.illinois.edu/newsletter/4...
Wind and frost have surprisingly strong effects on global patterns in leaf cuticle thickness! Latitude, biome and taxonomy matter too. Other climate variables not so much. #trait research from international team including @lawrensack.bsky.social @westobymark.bsky.social. doi.org/10.1111/nph....
For the connoisseur of plant traits: the environmental associations of kidney-bean vs dumbbell-shaped stomatal types and their implications. Similar climate associations of stomatal size and density for grasses and non-grasses across communities. www.nature.com/articles/s41...
How do parasitic plants find their prey? New study shows dodder vines use touch sensitivity and light detection to hunt victims. These master grafters even attempt to parasitize metal objects. Learn more: wp.me/pdRZhH-m3g #Botany #PlantScience 🧪

🌿 Excited to share our latest preprint! We tracked how plasmodesmata numbers evolved across the path from C₃ → C₄ photosynthesis in Flaveria - and found a stepwise increase in cell-to-cell connectivity. Thoughts or feedback are most welcome 😊 #PlantScience

Wait, what? I took ichthyology in college, and at no point did they explain to me that the reason early vertebrates were dominated by cartilaginous fish wasn't simplicity, but because PLANTS had not yet released enough calcium from rocks for it to become bioavailable for bone development. 🤯 🐟🌎

Balanophora is a parasitic plant that lacks chlorophyll, and steals its nutrients from tree roots. It lives beneath the rainforest floor, where once in a while, it sends up an orb that glows like the moon.
