Oetzi the Iceman has a new look. Decades after the famous glacier mummy was discovered in the Italian Alps, scientists have dug back into his DNA to paint a better picture of the ancient hunter.
They determined that Oetzi was mostly descended from farmers from present day Turkey, and his head was balder and skin darker than what was initially thought, according to a study published Wednesday in the journal Cell Genomics.
Oetzi, who lived more than 5,000 years ago, was frozen into the ice after he was killed by an arrow to the back. His corpse was preserved as a “natural mummy” until 1991, when hikers found him along with some of his clothing and gear — including a copper ax, a longbow and a bearskin hat. Since then, many researchers have worked to uncover more about the mummy, which is displayed at the South Tyrol Museum of Archaeology in Bolzano, Italy.
An earlier draft of Oetzi’s genome was published in 2012. But ancient DNA research has advanced since then, so scientists decided to take another look at the iceman’s genes, explained study author Johannes Krause, a geneticist at Germany’s Max Planck Institute for Evolutionary Anthropology. They used DNA extracted from the mummy's hip bone.
The updated genome is “providing deeper insights into the history of this mummy,” said Andreas Keller of Germany’s Saarland University. Keller worked on the earlier version but was not involved with the latest study.
Based on the new genome, Oetzi's appearance when he died around age 45 was much like the mummy looks today: It's dark and doesn't have much hair on it, said study author Albert Zink, head of the Institute for Mummy Studies at Eurac Research in Italy. Scientists previously thought the iceman was lighter-skinned and hairier in life, but that his mummified corpse had changed over time.
His genome also showed an increased chance of obesity and diabetes, the researchers reported.
And his ancestry suggests that he lived among an isolated population in the Alps, Zink said. Most Europeans today have a mix of genes from three groups: farmers from Anatolia, hunter-gatherers from the west and herders from the east. But 92% of Oetzi’s ancestry was from just the Anatolian farmers, without much mixing from the other groups.

As gas prices surge amid the Russian invasion of Ukraine, other nations could potentially transition faster to using clean energy than previously expected. Philip K. Verleger, a senior fellow at the Niskanen Center, joined Cheddar News to explain how this could be a possibility in the near future. "Part of the reason I think we have this invasion and the tantrum that's being thrown by Russia, terrible tantrum, is because the Russians were trying to slow down the transition," he said. "Ironically they speeded it up."
As Russia intensifies its war on Ukraine, President Biden announced a ban on oil imported from the aggressor nation. Critics of Russia have said this would be the best way to force Putin to pull back, but curbs on Russian oil exports are expected to send already skyrocketing oil and gas prices even higher, further impacting consumers, businesses, financial markets, and the global economy. Leslie Beyer, CEO of the Energy Workforce and Technology Council, joined Cheddar News' Closing Bell to discuss. "It's certainly going to increase pricing, but it is the right thing to do," she said. "The industry itself has already pulled out of the significant portion of its operations in Russia."

Vaccine maker Pfizer delayed its COVID shot for kids allegedly due to a lack of data on how it would perform against the omnicron variant, according to the Wall Street Journa. Peter Pitts, professor and founder of the Center for Medicine in the Public Interest and a former FDA associate commissioner, joined Cheddar News Wrap to break down why the authorization can't be rushed. "Going forward, the FDA wants to look at data specifically against omicron, and it looks like that's going to be a three-shot regimen versus two, which was efficient against delta but not omicron because obviously omicron is more infectious," said Pitts.

Bamboo-based toilet paper company Cloud Paper raised $5 million in a recent funding round. Its product is a bamboo-based alternative to traditional toilet paper made from trees, and its mission is to end the deforestation caused by traditional paper products. Cloud Paper says the raise will allow it to make significant investments in its supply chain, product development, and hiring. Ryan Fritsch, a co-founder of Cloud Paper, joined Cheddar News' Closing Bell to discuss.
Space tourism company World View plans to launch its first commercial flights in early 2024, with voyages to take off from iconic locations around the world like the Grand Canyon — but seemingly at a flexible price point. Dale Hipsh, president of tourism and exploration at World View, joined Cheddar to discuss what a trip to the stratosphere would look like with his company and its much less expensive take on space travel. "Our technology allows us to be more democratic, to offer more opportunities for people to experience near space, and that overview effect," he said. "So we're really thrilled to be bringing it to market."
A recent NOAA report found America's coastline could experience a century's worth of sea rise in just 30 years. By 2050, water on the U.S. coast will be 10-12 inches higher, causing major eastern cities to be hit regularly with floods, even on sunny days. Gary Mitchum, professor of physical oceanography at the University of South Florida, joins Cheddar News to discuss.
