Now published in Nature Biotechnology: go.nature.com/44P7nSm If you missed it, the TL;DR is in my April thread below

How do #cyanobacteria keep amorphous calcium carbonate (ACC) stable inside their cells? Our new #JACS paper shows — via solid-state NMR — that a protein shell and water molecules stabilize ACC. 👉 pubs.acs.org/doi/full/10.... #biomineralization @biomin-impmc.bsky.social @ulbruxelles.bsky.social

The Carbonate Forum will be back in 2026! Keep an eye on this account for regular news and updates - from the start of December.

Wound healing is a hallmark feature of all life, including single cells. In a new preprint, Ambika Nadkarni @biochembika.bsky.social investigates a new dimension in cellular wound healing: how cells recover AFTER the wound has been closed www.biorxiv.org/content/10.1...

Wow!!

In 2010, a scientist argued that 2.1 billion-year-old African specimens showed complex life appearing 500 million years ahead of schedule. His critics say they are — literally — fool's gold. At stake? The question of when and how complex life arose at all. My cover story (!) for @sciam.bsky.social!
