'Cutting edge' algae removal tech to be tried on Lake Okeechobee

Toxic algae blooms have threatened Florida's Lake Okeechobee for decades, the result of man-made engineering missteps, and political favoritism. The Army Corps of Engineers is working to correct the growing environmental menace.

Blue-green algae adapting easily to rising carbon dioxide levels

Rising CO2 levels will eventually force many of the Earth's life forms to adapt or end up being lost. One species, the blue-green algae, of which there are many toxin-producing varieties, is adapting very quickly, and that is not a good thing.

New type of bacteria-powered energy source

As part of the hunt for new types of energy, especially those that are renewable, microbiologists have been examining the properties of marine bacteria. One species, called Cyanothece 51142, is of particular interest.

Hot spring bacteria use red light for growth

Scientists have long been puzzled how bacteria grow in the near darkness of hot springs. It transpires that the bacteria can harness small quantities of red light from the little sunlight that permeates the depths.

Green biodiesel possibility

Scientists have successfully engineered two strains of blue-green algae like bacteria (cyanobacteria) to produce a liquid fuel. The fuel is being declared as an environmentally friendly alternative to fossil fuels.
