Nanostructure of 5,000-year-old mummy skin reveals insight into mummification process

Using cutting-edge microscopy techniques, researchers have gained insight into how human mummies can be extremely well-preserved for thousands of years. A team of scientists from Germany and Italy has investigated skin samples from Europe's oldest natural mummy, the 5,300-year-old "Iceman" who was buried in a glacier shortly after death in the Otzal Alps between Italy and Austria. The researchers found that the underlying structure of the mummy's skin is largely unaltered compared with the skin of a modern living human, likely maintaining its protective function due to dehydration.
