Scientists have discovered what is thought to be the oldest known mummies in the world in Southeast Asia dating back up to 12,000 years.
Mummification prevents decay by preserving dead bodies. The process can happen naturally in places such as the sands of Chile’s Atacama Desert or the bogs of Ireland, where conditions can fend off decomposition. Humans across various cultures also mummified their ancestors through embalming to honor them or send their souls to the afterlife.
Egypt’s mummies might be the most well-known, but until now some of the oldest mummies were prepared by a fishing people called the Chinchorro about 7,000 years ago in what is now Peru and Chile.

A new study published on Monday in the journal Proceedings of the National Academy of Sciences pushes that timeline back.
Researchers found human remains that were buried in crouched or squatted positions with some cuts and burn marks in various archeological sites across China and Vietnam, and to a lesser extent, from the Philippines, Laos, Thailand, Malaysia and Indonesia.
Studying the bones further, scientists discovered the bodies were likely exposed to heat. That suggested the bodies had been smoke-dried over a fire and mummified by hunter-gatherer communities in the area.
The practice “allowed people to sustain physical and spiritual connections with their ancestors, bridging time and memory,” study author Hirofumi Matsumura of Sapporo Medical University in Japan said in an e-mail.
Dating methods used on the mummies could have been more robust and it is not yet clear that mummies were consistently smoke-dried across all these locations in southeastern Asia, said human evolution expert Rita Peyroteo Stjerna of Uppsala University in Sweden, who was not involved with the research.
The findings offer “an important contribution to the study of prehistoric funerary practices,” she said in an e-mail.
Mummies are far from a thing of the past. Even today, indigenous communities in Australia and Papua New Guinea smoke-dry and mummify their dead, scientists said.
A humanoid robot that won a half-marathon race for robots in Beijing on Sunday ran faster than the human world record in a show of China’s technological leaps. The winner from Honor, a Chinese smartphone maker, completed the 21km race in 50 minutes and 26 seconds, said a WeChat post by the Beijing Economic-Technological Development Area, also known as Beijing E-Town, where the race began. That was faster than the human world record holder, Ugandan Jacob Kiplimo, who finished the same distance in about 57 minutes in March at the Lisbon road race. The performance by the robot marked a significant step forward
Four contenders are squaring up to succeed Antonio Guterres as secretary-general of the UN, which faces unprecedented global instability, wars and its own crushing budget crisis. Chile’s Michelle Bachelet, Argentina’s Rafael Grossi, Costa Rica’s Rebeca Grynspan and Senegal’s Macky Sall are each to face grillings by 193 member states and non-governmental organizations for three hours today and tomorrow. It is only the second time the UN has held a public question-and-answer, a format created in 2016 to boost transparency. Ultimately the five permanent members of the UN’s top body, the Security Council, hold the power, wielding vetoes over who leads the
South Korea’s air force yesterday apologized for a 2021 midair collision involving two fighter jets, a day after auditors said the pilots were taking selfies and filming during the flight and held them responsible for the accident. “We sincerely apologize to the public for the concern caused by the accident that occurred in 2021,” an air force spokesman told a news conference, adding that one of the pilots involved had been suspended from flying duties, received severe disciplinary action and has since left the military. The apology followed a report released on Wednesday by the South Korean Board of Audit and Inspection,
An earthquake registering a preliminary magnitude of 7.7 off northern Japan on Monday prompted a short-lived tsunami alert and the advisory of a higher risk of a possible mega-quake for coastal areas there. The Cabinet Office and the Japan Meteorological Agency said there was a 1% chance for a mega-quake, compared to a 0.1% chance during normal times, in the next week or so following the powerful quake near the Chishima and Japan trenches. Officials said the advisory was not a quake prediction but urged residents in 182 towns along the northeastern coasts to raise their preparedness while continuing their daily lives. Prime
