A giant meteorite boiled the oceans 3.2 billion years ago. Scientists say it was a ‘fertilizer bomb’ for life

A massive space rock, estimated to be the size of four Mount Everests, slammed into Earth more than 3 billion years ago — and the impact could have been unexpectedly beneficial for the earliest forms of life on our planet, according to new research.
Typically, when a large space rock crashes into Earth, the impacts are associated with catastrophic devastation, as in the case of the demise of the dinosaurs 66 million years ago, when a roughly 6.2-mile-wide (10-kilometer) asteroid crashed off the coast of the Yucatan Peninsula in what’s now Mexico.
But Earth was young and a very different place when the S2 meteorite, estimated to have 50 to 200 times more mass than the dinosaur extinction-triggering Chicxulub asteroid, collided with the planet 3.26 billion years ago, according to Nadja Drabon, assistant professor of Earth and planetary sciences at Harvard University. She is also lead author of a new study describing the S2 impact and what followed in its aftermath that published Monday in the journal Proceedings of the National Academy of Sciences.
“No complex life had formed yet, and only single-celled life was present in the form of bacteria and archaea,” Drabon wrote in an email. “The oceans likely contained some life, but not as much as today in part due to a lack of nutrients. Some people even describe the Archean oceans as ‘biological deserts.’ The Archean Earth was a water world with few islands sticking out. It would have been a curious sight, as the oceans were probably green in color from iron-rich deep waters.”
When the S2 meteorite hit, global chaos ensued — but the impact also stirred up ingredients that might have enriched bacterial life, Drabon said. The new findings could change the way scientists understand how Earth and its fledgling life responded to bombardment from space rocks not long after the planet formed.

Scientists say skeletal remains found in castle well belong to figure from 800-year-old saga
[url=https://kra16f.cc]kraken зайти[/url]
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. https://kra16f.cc

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.
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. https://kra16f.cc

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.”
