Recycling orbital satellites

No matter how painstakingly we choose the materials to build satellites, once a mission is over they are just so much junk. But what if one day they could be recycled in space for future missions – perhaps as construction ...

Bacteria from Salar de Uyuni in Bolivia conceal bioplastic

In Bolivia, in the largest continuous salt desert in the world, researchers from the Polytechnic University of Catalonia have found a bacterium that stores large amounts of PHB, a prized polymer. This biodegradable plastic ...

Biogas from animal waste in need of maturity

Biogas-based energy could solve both the environmental concern of agricultural waste and reduce dependency of fossil fuels, particularly in Eastern Europe, albeit at a steep production cost.

Super-microbes engineered to solve world environmental problems

Environmental problems, such as depleting natural resources, highlight the need to establish a renewable chemical industry. Metabolic engineering enhances the production of chemicals made by microbes in so-called "cell factories". ...

Team determines how estrogens to persist in dairy wastewater

Wastewater from large dairy farms contains significant concentrations of estrogenic hormones that can persist for months or even years, researchers report in a new study. In the absence of oxygen, the estrogens rapidly convert ...

New harvesting approach boosts energy output from bacteria

A team of scientists from University of Colorado Denver has developed a novel energy system that increases the amount of energy harvested from microbial fuel cells (MFCs) by more than 70 times. The new approach also greatly ...
