Paper That Makes Water Safe
A revolutionary microbial-based paper sensor has been developed, creating a cheap, sustainable and recyclable device for detecting toxic compounds in water. Inspired by the simplicity of litmus paper - commonly used for the rapid assessment of acidity in water 鈥� it consists of a microbial fuel cell (MFC), obtained by screen printing biodegradable carbon electrodes onto a single piece of paper. Dr Mirella Di Lorenzo and Dr Janet Scott, both from the University of Bath, demonstrate how it works to Roland Pease.

Global Warming is Shrinking Insects
