Central to coral reefs around the world is the deeply interdependent relationship between corals and algae. This interconnection is responsible for algae’s protected habitat, corals’ bright colors, and the mutual exchange of nutrients for photosynthesis. Algae growth is modulated by a process called self-shading, decreasing exposure to light. In an artificial setup, however, this process prevents researchers from growing coral quickly. To prevent this light … Continue reading 3D printed corals grow algae that photosynthesize more efficiently

First it was New Jersey’s Lake Hopatcong, then the Pacific Northwest, and most recently in Central Park. The culprit? An ancient and prolific family of microbes that have been shaping our world for millennia—cyanobacteria.” Cyanobacteria are bacteria that thrive in the same conditions that make algae flourish and … Continue reading Blue-Green Planet: It’s a cyanobacterial world, and we just live on it.
