Proteins and Water Control the Stability of the Intracellular Amorphous Calcium Carbonate Inclusions Formed by Cyanobacteria
The formation of stable intracellular amorphous calcium carbonate (ACC) inclusions is widespread among bacteria, yet the mechanisms underlying their long-term stabilization remain unresolved. In this ...

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.

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

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.

These Enigmatic ‘Fossils’ Could Rewrite the History of Life on Earth
Controversial evidence hints that complex life might have emerged hundreds of millions of years earlier than previously thought—and possibly more than once
