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 www.nature.com/articles/s41...

A transcriptomic hourglass in brown algae - Nature
Similar to other eukaryotes, brown algae exhibit transcriptome conservation that is consistent with the molecular hourglass model during differentiation in embryonic development.

Plant plasmodesmata bridges form through ER-dependent incomplete cytokinesis
Diverging from conventional cell division models, plant cells undergo incomplete division to generate plasmodesmata communication bridges between daughter cells. Although fundamental for plant multice...

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...
Woodcut with black ink on off-white background. A domestic black cat is prowling through vegetation, exuding the look and feel of her wild ancestors. Her eyes have been left free of all detail, making them appear to glow strikingly with the pure color of the light paper.

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: "Will the real Robert Hooke please stand up?" by Winfried S. Peters, in #ThePlantCell #PlantScience

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 📸 🧪
