Researchers are using naturally occurring algae to trace the source of nutrients polluting our rivers and bays. “We all love to visit our rivers and bays but when it rains and floods, soil is washed from forests, farmland and urban areas and pollutes these waterways. Algae are an important part of these ecosystems, but nutrients…

A native species of fast-growing and non-invasive microscopic algae could produce an alternative fuel up to 10 times more productive than existing biofuels, say scientists from The University of Queensland. Dr Evan Stephens and his research team have identified a number of algae strains that could be farmed to produce a renewable fuel that would…

A biotechnologist from the South Australian Research and Development Institute has taken using “everything but the pig’s squeal” to new lengths. Through clever recycling of pig waste, Andrew Ward has been able to produce feed for aquaculture, water for irrigation, and methane for energy. His ‘waste food chain’ can be applied to breweries, wineries and…

A test for  toxic algae could help save our coastal waters from attack by invading pests Coastal waters around the world are threatened by invaders lurking in the ballast water of cargo ships. A new global agreement will require ships to meet strict regulations to ensure they do not harbour any unwanted invaders. New technologies…
