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.
Tiny house with elaborate – and erotic – frescoes unearthed at Pompeii
[url=https://krmp12.cc]kraken зайти[/url]
Archaeologists have uncovered a tiny house in Pompeii that is filled with elaborate – and sometimes erotic – frescoes, further revealing the ornate way in which Romans decorated their homes.
Situated in the central district of the ancient city, the house is smaller than normal and unusually lacks the open central courtyard – known as an atrium – that is typical of Roman architecture, the Archaeological Park of Pompeii, which oversees the site, said in a statement Thursday.

This change could have occurred due to shifting trends in Roman – and particularly Pompeian – society, during the first century AD, archaeologists said.
Pompeii was destroyed by the eruption of Mount Vesuvius in AD 79 when its buildings and thousands of inhabitants were buried beneath layers of ash and pumice. This coating perfectly preserved the city for millennia, making it one of the most important archaeological sites in the world as it offers an unprecedented insight into Roman daily life.
This latest discovery spotlights the ornate decorations that rich Romans enjoyed in their homes – several frescoes depict mythical scenes and others are decorated with plant and animal motifs on a white background.
One small square painting set against a blue-painted wall depicts intercourse between a satyr and a nymph, while another shows Hippolytus, son of the mythical Greek king Theseus, and his stepmother Phaedra who fell in love with him before killing herself when he rejected her in disgust.
He served with the US Army in Iraq. Now he’s one of Asia’s top chefs and a Netflix ‘Culinary Class Wars’ judge

From a warzone in Iraq to a Michelin-starred kitchen and a hit Netflix show, chef Sung Anh’s path to the top of Asia’s fine dining scene has been anything but ordinary.
“Just like I did in the US Army, where I volunteered to go to the war, wanting to do something different — I decided to come here to Korea to try something different,” says the Korean-American chef and judge on hit reality cooking show “Culinary Class Wars,” which has just been green-lit for a second season.

Sung, 42, is the head chef and owner of South Korea’s only three-Michelin-starred restaurant, Mosu Seoul. In recent weeks, he has gained a new legion of fans as the meticulous and straight-talking judge on the new Netflix series. It’s this passion and unwavering drive to forge his own path that’s helped reshape fine dining in his birth home.
Born in Seoul, South Korea’s capital, Sung and his family emigrated to San Diego, California when he was 13.
“We were just a family from Korea, seeking the American Dream,” he says. “As an immigrant family, we didn’t really know English.”
As a teen growing up on the US West Coast, his mind couldn’t have been further from cooking.
“I went to school, got into college, but decided to join the US Army because that’s the only way I thought I could travel,” says the chef.
Over four years of service, he trained in bases across the country, before being deployed to his country of birth, South Korea and — following 9/11 — to the Middle East.
Scientists say skeletal remains found in castle well belong to figure from 800-year-old saga
[url=https://krmp12.cc]kraken market[/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.

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.
