Scientist from Indian Institute of Technology Kanpur (IITK) have developed a novel ternary nanocomposite (compound made of three different nano compounds) which can remove methylene blue from a solution when shone with visible or Ultra Violet (UV) light.
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.
