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.
New research reveals that cultural tolerance and political pressure, rather than just biological science, dictate the life or death of tigers in India and wolves in Germany.
