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.

Can these ultra-exclusive luxury destinations help extend your life? They’d certainly like to try
https://pinup-india.in/
When the Six Senses Residences Dubai Marina is completed in 2028, the gleaming 122-story building will be the tallest residential structure in the world, complete with luxury fitness and wellness amenities to match. Residents will be able to lift weights, take an outdoor yoga class or swim laps in a pool more than 100 stories high in the clouds.

But what if, by living there, people were also extending their lives? That’s the mission of the “longevity floor,” another amenity available to future residents of the Six Senses’ 251 apartments and “sky mansions.” This unique floor will include even more specialized offerings such as crystal sound healing, believed by its practitioners to reduce stress and improve sleep. Or residents can indulge in hyperbaric treatments, breathing in 100% oxygen in a pressurized chamber which has shown promising anti-aging results.

“The idea around it is that you’re not just purchasing a residence, you’re purchasing a lifestyle,” said Kevin Cavaco, director of marketing for Select Group, the building’s developer.

“You’re purchasing an opportunity to work on your true wealth — which is your longevity. You’re prolonging your time.”

Life extension may be a lofty — and dubious — pitch, but it’s a common theme among luxury fitness clubs, opulent new high rises and exclusive retreats. The trend coincides with new scientific studies and a parallel fixation in the tech world, but the provable science behind these promises is often murky.
Celebrity personal trainer and gym designer Harley Pasternak is used to designing programs for high-profile celebrities including Kim Kardashian, Lady Gaga and Halle Berry. But he’s noticed a shift in the past few years, he told CNN over email, as he’s gained an “influx” of tech founder clients.

“All of them are definitely more interested in aging, in a way that I’ve never seen prior to five years ago,” he said. “All kinds of biohacking tricks like heat exposure, cold, exposure, certain supplements, training, foraging, and even certain medications.”

The magical white stone wonderland with effervescent bathing pools
live casino 1xbet
From a distance, Pamukkale looks every bit like a ski resort, with a cascade of brilliant white slopes and a scattering of tourists at the top, seemingly preparing to slalom down into the valley below.

So why isn’t it melting away as midsummer temperatures nudge toward 100 Fahrenheit, or 37 Celsius, and the heat hangs in the shimmering air?

Because this unusual and beautiful wonder, located deep in the sunkissed hills of southwestern Turkey, isn’t snow at all. In fact the water it’s formed from sometimes spurts out of the ground at boiling point.

And those visitors milling around its upper reaches aren’t going anywhere fast. Most are here to take in the extraordinary spectacle – and either paddle or soak in some of the planet’s most photogenic pools.

Today, Pamukkale’s travertine limestone slopes and pools, filled with milky blue mineral water, are perfect for Instagram moments, especially as the magic hour evening sun casts their rippled surfaces in hues of pink.

Gateway to Hell
But this place was a tourist sensation thousands of years before social media, as first Greeks, then Romans flocked here for the thermal waters and to pay tribute at what was revered as a gateway to Hell.

Today, Pamukkale and the ancient city of Hierapolis, which sprawls across the plateau above the white terraces, are part of a UNESCO World Heritage site that pulls in coachloads of visitors. Typically, many visit for a couple of hours, but it’s worth spending at least a day in this geological and historical playground.
