Deep‐branching eukaryotes and early events in protist evolution
The first eukaryotes evolved from their archaean ancestors in the early Proterozoic, likely ca. 2000–1800 million years ago (Mya). Their macroscopic multicellular descendants, such as plants, heterok...

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

The amoeba Difflugia bacillifera builds its shell from things that contain silica, and it is not particular about the source. These ones have incorporated whole shells from another testate amoeba (Euglypha), along with diatoms, algal cysts and chunks of rock. #Amoebae #ProtistsOnSky #peatlands

Two Nanochloropsis gaditana cells visualized by quick-freeze deep-etch electron microscopy. Left cell displays a chloroplast containing thylakoids, a nucleus, a mitochondrion, and a fracture face of the plasma membrane. In the right cell, the innermost membrane, marked with pits, is the fractured outer membrane of the chloroplast envelope, above which is the fractured outer membrane of the chloroplast ER, above which is the granular cell wall.
