Researchers at the Polytechnic University of Turin are using DNA DNA from herring sperm cells to develop new types of flame retardant materials . They DNA DNA forms a protective coating when heated that prevents fire . The DNA breaks down into a polymer that chars into a foam - like material . researchers discovered it could create environmentally - friendly flame retardants . These could be used to protect fabrics , furniture and appliances from fire .
Researchers at the Polytechnic University of Turin are using DNA extracted from herring sperm cells to develop new types of flame retardant materials . They found DNA forms a protective coating when heated that resists fire . The DNA breaks down into a foam that chars into a ceramic-like material . Scientists believe it could create environmentally-friendly flame retardants . These could be used to protect fabrics , furniture and plastics from fire .
