🔬 New publication from BIOM in Science Advances! How did the vertebrate kidney evolve? Comparing catshark, lamprey & amphioxus embryos, Sylvie Mazan's team & collaborators show the primitive kidney arises from a somitic compartment. 👏 Congrats to all authors! 🔗 www.science.org/doi/10.1126/...

Good to see students working hard to dissect adults and collect eggs and sperm for fertilization from many different kinds of ascidian species.

Bilaterian BMP signaling gradients suggest an ancestral anti-neural role. Study of #cnidarians shows that #BMP signalling promotes neurogenesis; its "anti-neural" function is a side effect of its role in the DV axis @paulknabl.bsky.social @genikhovich.bsky.social @plosbiology.org 🧪 plos.io/4dJHoiR
In the box jellyfish Tripedalia cystophora, BMP signaling is active in ganglionic neurons of the umbrella, the ring nerve and in the rhopalium. Top left: Oral view of the umbrella, black arrowheads highlight the location of the rhopalia (rh). Top right: lateral and frontal detail of the rhopalium anatomy. Bottom, from left to right: pSMAD1/5 activity in the rhopalia, lateral view of the rhopalium, view from the top highlights pSMAD1/5 activity around the stalk, detailed view of the pit eye and the area around it (pSMAD1/5 is observed in a sector of the pit eye retina, the upper lens eye and some cells between the pit eye and the stalk).

These trees look like Jimmy Hendrix & Claude Monet did a collab, but this is just what the rainbow eucalyptus (Eucalyptus deglupta) looks like every day: fabulous. The only 'rainforest' eucalyptus, it's native to the Philippines & Indonesia, but introduced in Hawaii, Florida & California.
A photo taken from Smart Seeds Emporium.  It shows the almost violent shades of fluorescent green, red, brown, orange and green that are exposed by the peeling bark of the rainbow eucalyptus.
