The mysterious symbols found carved in Qatar’s desert

Some shoot out of the soft rock like reptiles bathing in the sun. Others are mysterious depressions resembling an ancient board game played all over the world. And a few are straight-up puzzling.

On a desolate and windswept corner of Qatar’s northeastern coast, among the sand dunes of the barren desert, lies Al Jassasiya, the Gulf country’s largest and most important rock art site.

Here, people centuries ago used a series of low-lying limestone outcrops as a canvas on which they carved symbols, motifs and objects that they observed in their environment.
Overall, archaeologists have found a total of some 900 rock carvings, or “petroglyphs,” at Al Jassasiya. They are mostly enigmatic cup marks arranged in various patterns, including rows and rosettes, but also eye-catching representations of sailing ships, usually seen from above but also depicted in linear profile, among other symbols and signs.

“Although rock art is common in the Arabian Peninsula, some of the carvings in Al Jassasiya are unique and cannot be found anywhere else,” Ferhan Sakal, head of excavation and site management at Qatar Museums, told CNN, referring to the petroglyphs of ships seen from a bird’s-eye view.

“These carvings represent a high degree of creativity and observation skills the part of] the artists who made them,” he said. “Also abstract thinking, as they were not able to see the dhow (a traditional ship) from above.”

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.

Sea robins are fish with ‘the wings of a bird and multiple legs like a crab’
kra8 cc
Some types of sea robins, a peculiar bottom-dwelling ocean fish, use taste bud-covered legs to sense and dig up prey along the seafloor, according to new research.

Sea robins are so adept at rooting out prey as they walk along the ocean floor on their six leglike appendages that other fish follow them around in the hope of snagging some freshly uncovered prey themselves, said the authors of two new studies published Thursday in the journal Current Biology.

David Kingsley, coauthor of both studies, first came across the fish in the summer of 2016 after giving a seminar at the Marine Biological Laboratory in Woods Hole, Massachusetts. Kingsley is the Rudy J. and Daphne Donohue Munzer Professor in the department of developmental biology at Stanford University’s School of Medicine.

Before leaving to catch a flight, Kingsley stopped at a small public aquarium, where he spied sea robins and their delicate fins, which resemble the feathery wings of a bird, as well as leglike appendages.

“The sea robins on display completely spun my head around because they had the body of a fish, the wings of a bird, and multiple legs like a crab,” Kingsley said in an email.
“I’d never seen a fish that looked like it was made of body parts from many different types of animals.”
Kingsley and his colleagues decided to study sea robins in a lab setting, uncovering a wealth of surprises, including the differences between sea robin species and the genetics responsible for their unusual traits, such as leglike fins that have evolved so that they largely function as sensory organs.

The findings of the study team’s new research show how evolution leads to complex adaptations in specific environments, such as the ability of sea robins to be able to “taste” prey using their quickly scurrying and highly sensitive appendages.

7 simple secrets to eating the Mediterranean way
кракен онион
What if “diet” wasn’t a dirty word?

During Suzy Karadsheh’s childhood in Port Said, Egypt, diet culture was nonexistent.

“My parents emphasized joy at the table, rather than anything else,” Karadsheh said. “I grew up with Mediterranean lifestyle principles that celebrate eating with the seasons, eating mostly whole foods and above all else, sharing.”

But when Karadsheh moved to the United States at age 16, she witnessed people doing detoxes or restricting certain food groups or ingredients. Surrounded by that narrative and an abundance of new foods in her college dining hall, she says she “gained the freshman 31 instead of the freshman 15.” When she returned home to Egypt that summer, “I eased back into eating the Mediterranean food that I grew up with. During the span of about two months, I shed all of that weight without thinking I was ever on a diet.”
To help invite joy back to the table for others — and to keep her family’s culinary heritage alive for her two daughters (now 14 and 22) — Atlanta-based Karadsheh launched The Mediterranean Dish food blog 10 years ago. Quickly, her table started getting filled with more than just her friends and family.

“I started receiving emails from folks whose doctors had prescribed the Mediterranean diet and were seeking approachable recipes,” Karadsheh said. The plant-based eating lifestyle, often rated the world’s best diet, can reduce the risk for diabetes, high cholesterol, dementia, memory loss and depression, according to research. What’s more, the meal plan has been linked to stronger bones, a healthier heart and longer life.

Preparing meals the Mediterranean way, according to Karadsheh, can help you “eat well and live joyfully. To us, ‘diet’ doesn’t mean a list of ‘eat this’ and ‘don’t eat that.’” Instead of omission, Karadsheh focuses on abundance, asking herself, “what can I add to my life through this way of living? More whole foods, vegetables, grains, legumes? Naturally, when you add these good-for-you ingredients, you eat less of what’s not as health-promoting,” she told CNN.

Automatic takeoffs are coming for passenger jets and they’re going to redraw the map of the sky
kra cc

In late 1965, at what’s now London Heathrow airport, a commercial flight coming from Paris made history by being the first to land automatically.

The plane – A Trident 1C operated by BEA, which would later become British Airways – was equipped with a newly developed extension of the autopilot (a system to help guide the plane’s path without manual control) known as “autoland.”

Today, automatic landing systems are installed on most commercial aircraft and improve the safety of landings in difficult weather or poor visibility.

Now, nearly 60 years later, the world’s third largest aircraft manufacturer, Brazil’s Embraer, is introducing a similar technology, but for takeoffs.

Called “E2 Enhanced Take Off System,” after the family of aircraft it’s designed for, the technology would not only improve safety by reducing pilot workload, but it would also improve range and takeoff weight, allowing the planes that use it to travel farther, according to Embraer.

“The system is better than the pilots,” says Patrice London, principal performance engineer at Embraer, who has worked on the project for over a decade. ”That’s because it performs in the same way all the time. If you do 1,000 takeoffs, you will get 1,000 of exactly the same takeoff.”

Embraer, London adds, has already started flight testing, with the aim to get it approved by aviation authorities in 2025, before introducing it from select airports.
