🌊 Kelp forests are estimated to be losing ~1.8% (~11,500 km²) of their area annually. The striking part? The carbon-sink capacity lost from the climate-driven decline is 1,000–10,000× larger than the gains achieved via seaweed restoration, afforestation & farming. journals.plos.org/plosbiology/...

Seaweed carbon removal cannot keep up with climate-driven loss
Seaweed forests are widely viewed as natural climate solutions, yet warming oceans are driving their rapid decline. This Essay reveals that losses are outpacing restoration efforts by orders of magnit...

(1/16) Nearly two-thirds of ocean carbon fixation flows through a diverse organelle: the pyrenoid. Our new paper maps its 3D architecture in the alga Chlorella and identifies new proteins — expanding the toolkit to engineer this CO2-concentrating machine into crops🧵 #Pyrenoid #CCM #Photosynthesis

Excited to share our latest preprint on #PhycologyFriday. We map out the carbon fixation pathway for the first time in a multicellular alga, the green seaweed Ulva, and reveal a unique Rubisco-Linker interaction in the pyrenoid, a chloroplast condensate. Below I summarize some key points. #seaweeds
