Protein shell discovery reveals how diatoms capture CO₂ so effectively

Tiny diatoms in the ocean are masters at capturing carbon dioxide (CO2) from the environment. They fix up to 20% of the Earth's CO2. A research team at the University of Basel, Switzerland, has now discovered a protein shell in these algae that is necessary for efficient CO2 fixation. This groundbreaking discovery can provide ideas for bioengineering approaches to reduce CO2 in the atmosphere.
