Cool... There are also some rare metabolic disorders that affect earwax. The most notable earwax scientific discovery of recent times is that of a 24cm wax earplug from a blue whale. Unlike humans which shed their earwax and dead skin cells, filter-feeding whales retain their earwax, recording life events similar to the way tree rings reveal arid and wet seasons during its lifetime. The earwax was analysed by Sascha Usenko, a environmental scientist at Baylor University in Waco, Texas. He and his team found that during the 12-year-old male whales life it came into contact with 16 different pollutants such as pesticides.
