Viral NblA proteins negatively affect oceanic cyanobacterial photosynthesis - Nature
Viral NblA accelerates the cyanophage infection cycle, directs degradation of the host phycobilisome and other proteins, and reduces host photosynthetic light-harvesting efficiency.

Diving through the purple sulfur bacteria layer of Fayetteville Green Lake with our ROV last month. This is the most intense density of PSB that I've seen in many years!

Now we show how seasonal extremes drive microbial shifts and mineralisation, offering a window into processes that shaped Earth’s first biostructures 🪨
