Caption: Arctic cyanobacteria research. Biologist taking samples of cyanobacteria from a lake in the Canadian Arctic. The black colour of the sample indicates that these cyanobacteria are resistant to ultraviolet rays, and this property will be investigated for use in sunblock creams. Cyanobacteria (formerly known as blue-green algae) are a photosynthesising form of bacteria. They were among the first lifeforms to appear on Earth, and oxygenated the atmosphere. They are found worldwide in most habitats, including oceans, fresh water, and soil.
