14,000-year-old ivory tools discovered in Alaska suggest how Clovis’ ancestors first arrived in the New World
Ancient tools discovered in Alaska could shed light on how humans first reached the Americas, a new study has found. These artifacts include items related to stone tool making and ocher, a red mineral often used in rituals, and are about 600 years older than similar artifacts from the Clovis people who lived further south, […]
A new genomic study suggests there are far fewer people related to Genghis Khan than previously assumed.
According to Kazakh folklore, the body of Genghis Khan’s eldest son Jochi is kept in a mausoleum in the Ulitau region in the country’s central highlands. But when archaeologists examined bodies recently unearthed from a medieval mausoleum, they did not find Jochi, but instead discovered a new genetic lineage that may have been inherited by […]
Obesity may increase chances of dying from serious infections, study finds
A new study of more than 500,000 people found that people who are obese are 70% more likely to be hospitalized or die from a serious infection than those who are not obese. The study found that obese people account for one in 10 deaths from infectious diseases worldwide. This association persisted even in obese […]
Blood Moon 2026: Where to live stream next week’s total lunar eclipse

Scientists discover ancient black holes are breaking the universe’s ‘velocity limit’, casting doubt on multiple theories
Amazingly voracious black holes from the dawn of the universe break two big rules. Not only does it exceed the “rate limit” for black hole growth, it also produces extreme X-ray and radio emissions, two characteristics that are not predicted to coexist. The object, a quasar known as ID830, is an extremely bright and active […]
Powerful software can reduce the time required to simulate large molecule reactions from weeks to just minutes.
A powerful quantum chemistry engine is now available to help scientists tackle complex chemical problems. The new technology has the potential to significantly speed up research in drug discovery, materials science and other fields, claims the system’s developer, QDX.
