End of Cling film.....Silk wrap invented

                Scientists have invented a cling film-like food wrap made from silk that can preserve fruit for more than week. It’s a natural, biodegradable alternative to plastic. International concern has been growing about plastic waste, particularly the amount that washes into the sea. One estimate is that by 2050 there will more plastic than fish in the world’s oceans. Now a team of biomedical engineers at Tufts University in the US have developed a technique that enables food to be coated with an almost invisible layer of fibroin, a protein found in silk, which helps make it one of nature’s toughest materials, according to report in The Independent. The lead researchers, Professor Fiorenzo Omenetto, said the world should probably move “towards processes that are more efficient and more naturally derived” and developed materials that “are closer to things that surround us, rather than having more man-made, processed materials for the general well being of our planet”.
