Sustainable transportation: Clearing the air on nitrogen doping

Proton-exchange membrane (PEM) fuel cells are an energy storage technology that will help lower the environmental footprint of transportation. These fuel cells make use of a chemical reaction known as oxygen reduction. This ...

Magnetic 'T-Budbots' made from tea plants kill and clean biofilms

Biofilms—microbial communities that form slimy layers on surfaces—are difficult to treat and remove, often because the microbes release molecules that block the entry of antibiotics and other therapies. Now, researchers ...

Scientists record rapid carbon loss from warming peatlands

Scientists at the Department of Energy's Oak Ridge National Laboratory have demonstrated a direct relationship between climate warming and carbon loss in a peatland ecosystem. Their study published in AGU Advances provides ...

Nanoparticles: Acidic alert

Researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have synthesized nanoparticles that can be induced by a change in pH to release a deadly dose of ionized iron within cells. This mechanism could potentially open ...

Metabolic diversity of the 'big six' of E. coli strains

NUS food scientists have discovered that the six major strains of Escherichia coli (E. coli) that cause foodborne illnesses have different metabolisms and tolerance towards acidic conditions.
