Explaining the icy mystery of the Dyatlov Pass deaths

A decades-old mystery from Soviet Russia could be explained by studying the science of snow.

The Golden State killer case spotlights how genetic testing can affect your—and your relatives'—privacy

Police managed to use consumer DNA test results to close a case 32 years after a killer was believed to have committed at least 12 murders and 50 rapes. Their "smoking gun": They compared a DNA sample from the crime scene to genetic data relatives had shared on an open-source genealogy database. The suspect was caught after investigators explored family trees on this database and connected the dots from over 100 distant relatives who had some percentage of DNA that matched the killer. (Some users may encounter a paywall.)

New evidence suggests the eruption's victims died as their blood boiled

The claims that Jesus was buried in the Shroud of Turin, preserved since 1578

The 14-foot linen cloth bears a faint image of a crucified man and is the most scientifically studied relic in history. The core dispute hasn't moved much: 1988 radiocarbon dating placed it in the 13th-14th century, while defenders argue the sample was contaminated by medieval repairs. No one disputes that scientists can't explain how the image was formed, which acts like a photographic negative and has no trace of paint or dye.

Historians estimate only 1% of shipwrecks have been discovered

The oldest known shipwreck dates to around 2,700–2,300 BCE, but evidence suggests humans started open-ocean sailing at least 50,000 years ago. Many have completely deteriorated but artifacts aboard the vessels remain, while many lack historical records of the event or location.

The oldest medical report of a near-death experience dates to around 1740

In 2014, Dr. Philippe Charlier, a medical doctor and archeologist, found a French medical book from 1740 that described the near-death experience of a pharmacist. Using the Greyson Scale, Charlier found that the incident would have rated at least 12/32, more than high enough to scientifically classify as an NDE by today’s standards.
