Fascinating. Identification of a developmental hourglass in brown seaweed (kelp) in mid embryogenesis, like plants & animals

Suggests evolutionary acquisition of multicelluarity relies on ancient genes that become entrenched early in multicellular lineages

Happy National Black Cat Day! Should it be international instead of national? Yes. But I'm not in charge so I can't do anything about it. Woodcut by Eileen Mayo, 1938. collections.vam.ac.uk/item/O726847...

Excited our paper on thermomorphogenesis of root growth has been published! Check it out to read up on how root cell division is flexible, elongation is constrained, and cryptochrome2 has a cool role to play in temperature responses. doi.org/10.1093/pcp/...

Making yourself heard: why well-exposed flowers are an adaptation for bat pollination ($)

"Our results support the idea that exposure increases apparency, making the flowers easier to detect via echolocation."

Cool new work from Pierre Gautrat and @ronaldpierik.bsky.social in Natcomms on root-to-shoot signaling via cytokinin, regulating shade avoidance responses and nutrient acquisition. So complex! 😱

When I wrote my Short History of Plant Microscopy, I wondered when I couldn't find any reference to 'monk's chambers' in Robert Hooke's "Micrographia". Apparently I'm not the only one who wondered:

The swamp-dwelling ‘bald cypress’ is today’s #SpookyScience feature (and Louisiana’s state 🌲)!

The bald cypress is a pneumatophore, with roots growing just below the surface then protruding ⬆️ (believed to help the tree breathe). The tree’s “knees” don’t always look this spooky, but what a shot 📸 🧪
