Scientists from Indian Institute of Technology, Bombay, find a way to convert undesirable heat energy from electronic devices to electricity and reconverting this into electricity using the concept of thermoelectric effect - a physical phenomenon where a difference in the temperature between two contacts leads to a difference in the voltage, and hence flow of electricity.
The study from IISc found a previously unidentified yeast-like symbiont inside the lac insect Kerria lacca, which gives the insect its distinctive red colour and, may also provide other nutrients in return for shelter.
