- 2013 September-October, Katie L. Burke, “In the News”, in American Scientist[1], archived from the original on 30 November 2014:
- Oxygen levels on Earth skyrocketed 2.4 billion years ago, when cyanobacteria evolved photosynthesis: […] . The evolutionary precursor of photosynthesis is still under debate, and a new study sheds light. The critical component of the photosynthetic system is the “water-oxidizing complex”, made up of manganese atoms and a calcium atom.
- 2024 August 6, Ricardo Treviño, “Self-Healing Concrete Help Buildings Seal Themselves”, in TecScience[2], archived from the original on 19 January 2025:
- “This material has a specific hardness and is chemically very stable. It forms naturally from calcium alone, but bacteria accelerate the transformation into calcium carbonate,” explains Alejandro Montesinos, head of the Decarbonization, Climate Change, and Circular Economy Research Group at Tec de Monterrey and a member of the Institute of Advanced Materials and Sustainable Manufacturing.
- (countable) An atom of this element.
