Earth ring theory may shed light on an unexplained ancient climate event, scientists say
kra18 at
Famously known for its extensive ring system, Saturn is one of four planets in our solar system that have the distinctive feature. And now, scientists hypothesize that Earth may have sported its own ring some 466 million years ago.
During the Ordovician Period, a time of significant changes for Earth’s life-forms, plate tectonics and climate, the planet experienced a peak in meteorite strikes. Nearly two dozen impact craters known to occur during this time were all within 30 degrees of Earth’s equator, signaling that the meteoroids may have rained down from a rocky ring around the planet, according to a study published September 12 in the journal Earth and Planetary Science Letters.

“It’s statistically unusual that you would get 21 craters all relatively close to the equator. It shouldn’t happen. They should be randomly distributed,” said lead author Andrew Tomkins, a geologist and professor of Earth and planetary sciences at Monash University in Melbourne, Australia.
Not only does the new hypothesis shed light on the origins of the spike in meteorite impacts, but it also may provide an answer to a previously unexplained event: A global deep freeze, one of the coldest climate events in Earth’s history, may have been a result of the ring’s shadow.
Scientists are hoping to find out more about the possible ring. It could help answer the mysteries of Earth’s history as well as pose new questions about the influence an ancient ring could have had on evolutionary development, Tomkins said.

This teen became the youngest person to summit the world’s highest peaks. Now he wants others to follow in his footsteps

Nima Rinji Sherpa’s ears are still tinged black from wind chill, an occupational hazard of climbing to heights where humans struggle to breathe, and where the weather can turn deadly in an instant.
This month, Nima became the youngest person to summit all 14 of the world’s highest peaks, but the 18-year-old Nepalese mountaineer is already getting ready for his next big feat.

Speaking to CNN via video call from the Nepali capital Kathmandu last week, Nima said he’s taking a couple weeks’ rest before preparing to climb the world’s eighth-highest mountain, Manaslu, with Italian mountaineer Simone Moro – in winter, alpine-style.
“That means we’re climbing an 8,000-meter mountain in winter… There’s no fixed ropes for us, there’s no (supplemental) oxygen for us, there is no support for us. So, it’s like pure human endurance,” Nima said. “It has never been done in the history of mountaineering.”
After that, “I’ll take some rest,” Nima laughed.
On October 9, Nima reached the top of the 8,027-meter (26,335-foot) Shishapangma along with his partner Pasang Nurbu Sherpa. For Nima, it was the final of the “eight-thousanders,” the 14 peaks recognized by the International Climbing and Mountaineering Federation as standing more than 8,000 meters above sea level.
Describing the moment of summiting the final peak as “pure joy,” Nima said his motivation comes from his family, many of whom are renowned mountaineers.
His father, Tashi Lakpa Sherpa, has climbed Everest nine times, and at age 19 became the youngest person to summit without bottled oxygen. His uncle Mingma Sherpa became the first South Asian climber to summit the 14 peaks in 2011.
“My uncles and my father, they are way more successful than I would ever be because they came from a very small village. To even dream about being this successful, for them it was really hard,” Nima said. “I have the privilege that they didn’t have.”

Scientists say skeletal remains found in castle well belong to figure from 800-year-old saga
кракен вход
Researchers have connected the identity of skeletal remains found in a well at Norway’s Sverresborg castle to a passage in a centuries-old Norse text.
The 800-year-old Sverris saga, which follows the story of the real-life King Sverre Sigurdsson, includes the tossing of the body of a dead man — later known as “Well-man” — down a well during a military raid in central Norway in 1197.

It’s likely, according to the text, that raiders lobbed the body into the well to poison the main water source for locals, but little else is said about the man or who he was in the saga.
Researchers initially uncovered the bones in the castle’s well in 1938, but they were only able to carry out a visual analysis at the time. Now, scientists have an array of analytical techniques at their disposal, including genetic sequencing and radiocarbon dating.
A new study on the remains, published Friday in the Cell Press journal iScience, reveals unprecedented insights into Well-man’s appearance based on in-depth research on samples of his teeth.
“This is the first time that a person described in these historical texts has actually been found,” said study coauthor Michael D. Martin, a professor in the department of natural history at the Norwegian University of Science and Technology’s University Museum in Trondheim, in a statement.
“There are a lot of these medieval and ancient remains all around Europe, and they’re increasingly being studied using genomic methods.”
The findings not only shed fresh light on what Well-man looked like but also who he was, with a surprising twist about how he ended up in a Norse saga.

They’ve sailed across Southeast Asia for centuries. Now, these sea nomads are being forced to live on land

Bilkuin Jimi Salih doesn’t remember how old he was when he learned to dive, only, that all the men in his family can do it.
It might have been his grandfather who taught him, or his father, or even an uncle or cousin. He recalls swimming dozens of feet underwater among the reefs, collecting spider conches, abalone and sea cucumbers to sell at the local fish market.
“One of our specialties is that, because we live on the sea and we’re always in the sea, we can dive in the water for a long time,” says Salih, via a translator. “We learn by observing, and from there, we develop our own technique.”
To most people, Salih’s free diving skills are highly unusual; but not to his community. Salih is Bajau Laut, an indigenous seafaring group in Southeast Asia that has lived a semi-nomadic lifestyle on the ocean for centuries. Living on boats and fishing for income and sustenance, the Bajau Laut aren’t just reliant on the sea: they’re biologically adapted to it, with larger spleens that give them the ability to hold their breath for far longer than the average person.
“We’re very comfortable in the water,” says Salih. The 20-year-old was born on board a lepa, a type of houseboat, on the shore of Omadal Island, off the coast of Semporna in Malaysian Borneo.
