Water and life
stargate finance
Lightning is a dramatic display of electrical power, but it is also sporadic and unpredictable. Even on a volatile Earth billions of years ago, lightning may have been too infrequent to produce amino acids in quantities sufficient for life — a fact that has cast doubt on such theories in the past, Zare said.
Water spray, however, would have been more common than lightning. A more likely scenario is that mist-generated microlightning constantly zapped amino acids into existence from pools and puddles, where the molecules could accumulate and form more complex molecules, eventually leading to the evolution of life.
“Microdischarges between obviously charged water microdroplets make all the organic molecules observed previously in the Miller-Urey experiment,” Zare said. “We propose that this is a new mechanism for the prebiotic synthesis of molecules that constitute the building blocks of life.”
However, even with the new findings about microlightning, questions remain about life’s origins, he added. While some scientists support the notion of electrically charged beginnings for life’s earliest building blocks, an alternative abiogenesis hypothesis proposes that Earth’s first amino acids were cooked up around hydrothermal vents on the seafloor, produced by a combination of seawater, hydrogen-rich fluids and extreme pressure.
Researchers identified salt minerals in the Bennu samples that were deposited as a result of brine evaporation from the asteroid’s parent body. In particular, they found a number of sodium salts, such as the needles of hydrated sodium carbonate highlighted in purple in this false-colored image – salts that could easily have been compromised if the samples had been exposed to water in Earth’s atmosphere.

Yet another hypothesis suggests that organic molecules didn’t originate on Earth at all. Rather, they formed in space and were carried here by comets or fragments of asteroids, a process known as panspermia.
“We still don’t know the answer to this question,” Zare said. “But I think we’re closer to understanding something more about what could have happened.”
Though the details of life’s origins on Earth may never be fully explained, “this study provides another avenue for the formation of molecules crucial to the origin of life,” Williams said. “Water is a ubiquitous aspect of our world, giving rise to the moniker ‘Blue Marble’ to describe the Earth from space. Perhaps the falling of water, the most crucial element that sustains us, also played a greater role in the origin of life on Earth than we previously recognized.”

A more organic way to see this coast is by the multi-day coastal ferry, the long-running Sarfaq Ittuk, of the Arctic Umiaq Line. It’s less corporate than the modern cruise ships and travelers get to meet Inuit commuters. Greenland is pricey. Lettuce in a local community store might cost $10, but this coastal voyage won’t break the bank.
The hot ticket currently for exploring Greenland’s wilder side is to head to the east coast facing Europe. It’s raw and sees far fewer tourists, with a harshly dramatic coastline of fjords where icebergs drift south. There are no roads and the scattered population of just over 3,500 people inhabit a coastline roughly the distance from New York to Denver.
A growing number of small expedition vessels probe this remote coast for its frosted scenery and wildlife. Increasingly popular is the world’s largest fjord system of Scoresby Sound with its sharp-fanged mountains and hanging valleys choked by glaciers. Sailing north is the prosaically named North East Greenland National Park, fabulous for spotting wildlife on the tundra.
Travelers come to see polar bears which, during the northern hemisphere’s summer, move closer to land as the sea-ice melts. There are also musk oxen, great flocks of migrating geese, Arctic foxes and walrus.
Some of these animals are fair game for the local communities. Perhaps Greenland’s most interesting cultural visit is to a village that will take longer to learn how to pronounce than actually walk around — Ittoqqortoormiit. Five hundred miles north of its neighboring settlement, the 345 locals are frozen in for nine months of the year. Ships sail in to meet them during the brief summer melt between June and August.
Locked in by ice, they’ve retained traditional habits.
“My parents hunt nearly all their food,” said Mette Barselajsen, who owns Ittoqqortoormiit’s only guesthouse. “They prefer the old ways, burying it in the ground to ferment and preserve it. Just one muskox can bring 440 pounds of meat.”

Siham Haleem, a private tour guide for 15 years, says that Doha now has many world-class, modern museums — the National Museum of Qatar being a firm personal favorite. And yet he says that visiting Sheikh Faisal’s museum should still be on everybody’s to-do list.

“For those eager to learn about Qatar’s — and the region’s — heritage and beyond, the museum is an ideal destination,” he says. “Personally, I’m captivated by the car collection, the fossils, and especially the Syrian house, painstakingly transported and reassembled piece by piece.”
Stephanie Y. Martinez, a Mexican-American student mobility manager at Texas A&M University in Qatar likes the museum so much she includes it on all of her itineraries for students visiting from the main campus in Texas.
“The guided tours are very detailed, and the collections found at the museum have great variety and so many stories to unfold,” she says. “Truly, the museum has something to pique everyone’s interest. My favorites are the cars and the furniture exhibits showcasing wood and mother-of-pearl details. Definitely one of my favorite museums in Qatar, every time I visit I learn something new.”
Raynor Abreu, from India, also had praise for the unusual and immense collection.
“Each item has its own story, making the visit even more interesting,” he says. “It’s also impressive to know that Sheikh Faisal started collecting these unique pieces when he was very young. Knowing this makes the museum even more special, as it reflects his lifelong passion for history and culture.”
It takes time and dedication to truly examine the many collections within the museum — especially since most of them are simply on display without explanation.
Eclectic it may be, but it’s hard to fault the determination of Sheikh Faisal, who has brought together items that tell the story of Qatar and the Middle East.
Sarah Bayley, from the UK, says she visited the museum recently with her family, including 16 and 19-year-old teenagers, and was won over by its sheer eccentricity.
“Amazing. Loved it. It is a crazy place.”

Challenging our perceptions of ‘perfection’
traderjoexyz exchange
With health influencers raising the bar for success, the wellness space now often feels like a performative space where people strive to showcase peak physical and mental strength.
While seeing others’ achievements can be motivating, it can also be discouraging if your progress doesn’t match theirs.
Each person is chasing the perfect version of themselves — whether it’s a body or a lifestyle — which is dangerous because this is typically an impossible or dangerous version to achieve, Curran said. He added that this type of comparison creates a dangerous cycle in which people constantly feel dissatisfied with their own progress.
“It’s a fantasy in many ways, and once you start chasing after it, you constantly find yourself embroiled in a sense of doubt and deficit,” he said.
Curran also noted that wellness challenges can be particularly damaging for women who struggle with perfectionism, as they tend to be bombarded with impossible beauty standards and societal expectations.
Renee McGregor, a UK-based dietitian who specializes in eating disorders and athlete performance, encourages people to approach wellness trends with curiosity and skepticism. That’s because some influencers and celebrities could be promoting products because there’s a financial benefit for them.
“The thing to ask yourself about the person you’re taking advice from is what do they gain from it?” McGregor said. “If they are going to gain financially, then you know that they (could be willing) to sell you a lie.”
Whether you want to try a new challenge or product that promises amazing results, McGregor suggests doing your research and seeking diverse perspectives, including consulting with doctors when possible.

New design revealed for Airbus hydrogen plane
beefy fi
In travel news this week: Bhutan’s spectacular new airport, the world’s first 3D-printed train station has been built in Japan, plus new designs for Airbus’ zero-emission aircraft and France’s next-generation high-speed trains.
Grand designs
European aerospace giant Airbus has revealed a new design for its upcoming fully electric, hydrogen-powered ZEROe aircraft. powered by hydrogen fuel cells.
The single-aisle plane now has four engines, rather than six, each powered by their own fuel cell stack.
The reworked design comes after the news that the ZEROe will be in our skies later than Airbus hoped.
The plan was to launch a zero-emission aircraft by 2035, but now the next-generation single-aisle aircraft is slated to enter service in the second half of the 2030s.
Over in Asia, the Himalayan country of Bhutan is building a gloriously Zen-like new airport befitting a nation with its very own happiness index.
Gelephu International is designed to serve a brand new “mindfulness city,” planned for southern Bhutan, near its border with India.
In rail travel, Japan has just built the world’s first 3D-printed train station, which took just two and a half hours to construct, according to The Japan Times. That’s even shorter than the whizzy six hours it was projected to take.
France’s high-speed TGV rail service has revealed its next generation of trains, which will be capable of reaching speeds of up to 320 kilometers an hour (nearly 200 mph).
The stylish interiors have been causing a stir online, as has the double-decker dining car.
Finally, work is underway in London on turning a mile-long series of secret World War II tunnels under a tube station into a major new tourist attraction. CNN took a look inside.

Mindful wellness challenges
If you’re the type of person who thrives on challenges and pushing your limits, this doesn’t mean you need to shy away from wellness challenges altogether. But before diving in, take a step back and ask yourself if you’re pursuing the challenge for the right reasons, McGregor said.
velodrome finance
Some people want to try these challenges because they believe something is missing from their life, and they’re looking to attain “worth” or receive validation, McGregor noted.
A good way to assess your motivation is by considering whether the challenge will benefit your health or if it’s about showcasing your accomplishments on social media or some other reason.
Before trying any new trend, make sure you have the foundation to handle it and be aware of any potential risks, McGregor said.
For casual runners, this might mean signing up for a 5K but building your endurance gradually while incorporating other strength training exercises into your routine. For more intense challenges, such as a marathon, McGregor encourages people to consult with professionals or a coach who can monitor your progress and condition along the way.
Focusing on sustainable habits
Both McGregor and Curran emphasize the importance of fostering sustainable health habits before embarking on more extreme challenges.
Rather than chasing the idea of being “healthy,” McGregor suggests focusing on actual healthful behaviors and starting small.
If you’re a highly sedentary person and want to add more movement to your day, try doing lunges while brushing your teeth or taking short walks throughout your typical routine.

Scientists redid an experiment that showed how life on Earth could have started. They found a new possibility
safepal
In the 1931 movie “Frankenstein,” Dr. Henry Frankenstein howling his triumph was an electrifying moment in more ways than one. As massive bolts of lightning and energy crackled, Frankenstein’s monster stirred on a laboratory table, its corpse brought to life by the power of electricity.
Electrical energy may also have sparked the beginnings of life on Earth billions of years ago, though with a bit less scenery-chewing than that classic film scene.
Earth is around 4.5 billion years old, and the oldest direct fossil evidence of ancient life — stromatolites, or microscopic organisms preserved in layers known as microbial mats — is about 3.5 billion years old. However, some scientists suspect life originated even earlier, emerging from accumulated organic molecules in primitive bodies of water, a mixture sometimes referred to as primordial soup.
But where did that organic material come from in the first place? Researchers decades ago proposed that lightning caused chemical reactions in ancient Earth’s oceans and spontaneously produced the organic molecules.
Now, new research published March 14 in the journal Science Advances suggests that fizzes of barely visible “microlightning,” generated between charged droplets of water mist, could have been potent enough to cook up amino acids from inorganic material. Amino acids — organic molecules that combine to form proteins — are life’s most basic building blocks and would have been the first step toward the evolution of life.

Retirees 'stunned' as market turmoil over tariffs shrinks their 401(k)s
Americans nearing retirement and recent retirees said they were anxious and frustrated following a second day of market turmoil that hit their 401(k)s after President Donald Trump’s escalation of tariffs.
kra1 at
As the impending tariffs shook the global economy Friday, people who were planning on their retirement accounts to carry them through their golden years said the economic chaos was hitting too close to home.
kra35 сс
Some said they are pausing big-ticket purchases and reconsidering home renovations, while others said they fear their quality of life will be adversely affected by all the turmoil.
“I’m just kind of stunned, and with so much money in the market, we just sort of have to hope we have enough time to recover,” said Paula, 68, a former occupational health professional in New Jersey who retired three years ago.
Paula, who spoke on the condition of anonymity because she feared retaliation for speaking out against Trump administration policies, said she was worried about what lies ahead.
https://kra25a.cc
“What we’ve been doing is trying to enjoy the time that we have, but you want to be able to make it last,” Paula said Friday. “I have no confidence here.”
Trump fulfilled his campaign promise this week to unleash sweeping tariffs, including on the United States’ largest trading partners, in a move that has sparked fears of a global trade war. The decision sent the stock market spinning. On Friday afternoon, the broad-based S&P 500 closed down 6%, the tech-heavy Nasdaq dropped 5.8%, and the Dow Jones Industrial Average fell more than 2,200 points, or about 5.5%.

A tiny rainforest country is growing into a petrostate. A US oil company could reap the biggest rewards
swell network
Guyana’s destiny changed in 2015. US fossil fuel giant Exxon discovered nearly 11 billion barrels of oil in the deep water off the coast of this tiny, rainforested country.
It was one of the most spectacular oil discoveries of recent decades. By 2019, Exxon and its partners, US oil company Hess and China-headquartered CNOOC, had started producing the fossil fuel.? They now pump around 650,000 barrels of oil a day, with plans to more than double this to 1.3 million by 2027.
Guyana now has the world’s highest expected oil production growth through 2035.
This country — sandwiched between Brazil, Venezuela and Suriname — has been hailed as a climate champion for the lush, well-preserved forests that carpet nearly 90% of its land. It is on the path to becoming a petrostate at the same time as the impacts of the fossil fuel-driven climate crisis escalate.
While the government says environmental protection and an oil industry can go hand-in-hand, and low-income countries must be allowed to exploit their own resources, critics say it’s a dangerous path in a warming world, and the benefits may ultimately skew toward Exxon — not Guyana.
