Scientists from Indian Institute of Space Science and Technology (IIST), Thiruvananthapuram have possibly designed the first sustainable molecular keypad lock, which can also be used as a sensor of a poisonous pesticide.
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.
