Bacteria-based batteries, a new armored dinosaur, India's forest bridges and more from around the web

A Battery Powered by Bacteria and Sweat Researchers from the University of Massachusetts Amherst have engineered a bacteria-based battery that can produce power from human sweat. The key to their innovation is bacterium Geobacter sulfurreducens, a bacteria that can produce electricity and has been used to explore microbial batteries. However, its need to be fed a constant diet has limited its functionality. To get around …

A Battery Powered by Bacteria and Sweat

Researchers from the University of Massachusetts Amherst have engineered a bacteria-based battery that can produce power from human sweat. The key to their innovation is bacterium Geobacter sulfurreducens, a bacteria that can produce electricity and has been used to explore microbial batteries. However, its need to be fed a constant diet has limited its functionality. To get around this, the researchers grew the bacteria sustainably …

The Organic Source of Spring’s Distinct Scent

The unmistakable (and hopeful) scent that emerges around springtime has long been traced to an organic source: the soil-based compound geosmin. Scientists from the Swedish University of Agricultural Sciences, the John Innes Centre and Lund University have attributed the familiar yet often unplaceable smell—much like a rainy day or freshly turned earth—to a “symbiotic relationship between a six-legged worm, known as the springtail, and Streptomyces, …
