Mummification
Chemists at the University of Bristol analyzed the air around tiny fragments of Egyptian mummies to identify volatile organic compounds linked to embalming materials. The study, covering remains from 3200 BC to 395 AD, found 81 distinct compounds from oils, resins, beeswax, and bitumen. These clues show mummification practices grew more complex over time.

The mummified remains of a teenage boy, turned entirely green by a copper burial box, have been analyzed in Italy. Buried around three centuries ago in Bologna, the discovery provides new insights into copper's preservative effects on human tissue. The boy, aged 12 to 14, is the only near-complete green mummy known.
