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.
Researchers are using luminescence dating to date samples of the mineral jarosite from Kachchh, Gujarat. Due to its geological similarities, this mineral is considered a good Martian analogue.
