In future, the Zika virus could be detected using mobile phone cameras. Meanwhile, an American research team has been banking on the phone’s magnetometer - not for navigation, but for reading blood sugar levels. First they created a small sensor containing a double-layered hydrogel embedded with tiny magnetic particles. Then they attached it to the smartphone above the magnetometer....

Some fish perceive their surroundings in the dark. Now, a Chinese-South Korean research team has developed a sensor that can recognise nearby objects without touching them. Key to the enterprise is a composite film made from two highly conductive materials. A polymer based on silicon (polydimethylsiloxane) and a few organic macromolecules (graphitic carbon nitride), which are mixed and then...
