we're on the cover!
At @szndohrn.bsky.social, the floor tiles have stitching and segmentation artifacts :) Just finished teaching the marvels of spatial omics to the great group of PhD students of @zoocell.biologists.social.ap.brid.gy, together with @alvarocrevenna.bsky.social. What a week! 🔬🍕🍝🍷🧪
Finding molecular tags that localise fluorescent proteins to the cell membrane was the goal of our latest paper, now published in Development @dev-journal.bsky.social. The tags act as address labels, sending proteins to the cell membrane, where they highlight the shape and arrangement of cells. 2/9
There are just a few days (and spots!) left to apply to this EM course with a focus on marine samples 🌊 do not miss it!
We are excited to share that we are hosting a hands-on course on "Electron Microscopy of Marine Environmental Samples" 🔬🌊
📍Naples, Italy 🗓️ 8th-11th of April 2026
If you are interested, check the program below!
Registration is open until the 12th of February. We look forward to seeing you there!

EMHOC’s preliminary program is out. Check it out to stay updated!
Our work on the evolution of the regulatory genome of echinoderms is now out in @natecoevo.nature.com. Led by my former PhD Marta Magri, Danila Voronov & Saoirse Foley. Great collaboration of Arnone, Hinman & Maeso labs, started long time ago with our missed José Luis Gomez-Skarmeta: rdcu.be/eXX8l
These images show live embryos of animals (jellyfish, crustacean, worm, sea urchin, sea squirt, beetle) and one of animals closest single-celled relatives. They were captured taking advantage of fluorescent proteins localised on the outer membrane of cells, allowing us to observe cell outlines. 1/9
Thrilled to present our comparative study on the evolution of zygotic genome activation (ZGA)!! 🥚🧬
Amazing PhD work of @campobes.bsky.social together with @fedemantica.bsky.social and many collaborators! @melisupf.bsky.social @crg.eu. Thread below 1/15

Summary: Screening a toolkit of diverse membrane-localising tags identifies candidates that efficiently localise proteins to the plasma membrane in a wide range of animals and choanoflagellates.

The conservation of genome regulatory elements over long periods of evolution is not limited to vertebrates, as previously thought, but also in echinoderms (invertebrates). This is one of the most not...
