   During production, White revealed to Gries that Greg is “very sinister.” That became rather irrefutable by the season’s climax, which saw Tanya’s demise orchestrated by her now-husband.

   Come Season 3, Gries had to rewrite Greg’s backstory again, this time drawing from some unlikely sources for inspiration, like HBO docuseries “The Jinx,” about late convicted killer Robert Durst, and the case involving the man who came to be known as the Tinder Swindler.

   Gries said he was struck by Durst’s “kind of seemingly even keel personality,” which served as a model for where Greg was headed, someone “who doesn’t really show a great deal of emotion, doesn’t seem to get too angry, just gets a little bit irritated and is dangerous.”

   “There’s a bridled rage underneath. And those kind of people I find – at least with respect to Gary, Greg, Gary – fascinating,” he said.

   And yet, while searching for an empathetic way back to portraying his character, Gries kept wondering if there was anything still redeeming about Greg.
   An important “wake up moment” came during a decisive conversation he had with White just before filming in Thailand, in which the show’s creator said of Greg, in no uncertain terms: “He’s a psychopath.”

   “And that was it. It was like, ‘back to the drawing board.’ And it really did help me,” Gries said.

   The penultimate episode of the series will air on Sunday, an evening that thanks to “Lotus” and other shows has again become a night of appointment viewing amid a general move away from binge watching. Gries said he appreciates the shift.

   “We’re a society that in a weird way doesn’t understand the beauty of waiting. The beauty of the space between the notes,” he shared. “If I binged (‘White Lotus’) I’d feel like I just ate too many chocolates. It just wouldn’t be the same. You need to process this.”

   “The White Lotus” airs Sundays at 9 p.m. EDT on HBO, with the episode available to stream on Max. HBO and Max, like CNN, are owned by the same parent company, Warner Bros. Discovery.

2. Wellness perfectionism doesn’t exist. Focus on these sustainable habits
   sushiswap
   ou’re scrolling through your phone when you stumble upon the next viral trend: an influencer claiming that following their incredibly strict diet will help you achieve their jaw-dropping physique. Or you see a fresh-faced runner swearing you can run a marathon without any training — just like they did.

   Whether or not you’re actively searching for wellness advice, it’s nearly impossible to avoid hearing about the latest health craze making bold guarantees of transformation.

   As you wonder if these claims hold any truth, you might also question why people often feel motivated to dive into intense challenges — when seemingly simple habits, such as getting enough sleep or eating more vegetables, often feel much harder to tackle.

   Many of us are drawn to these extreme challenges because we’re craving radical change, hoping it will help prove something to ourselves or to others, experts say.

   “We always see these kinds of challenges as opportunities for growth, particularly if we’re in a phase of our life where we’ve let ourselves go,” said Dr. Thomas Curran, associate professor of psychology at the London School of Economics and Political Science and an expert on perfectionism. “Maybe we feel that we need to be healthier, or we just had a breakup or (major) life event.”
   With social media amplifying these movements, it’s easy to see why people are increasingly drawn to the idea of achieving the “perfect” version of themselves. But before jumping into a new wellness challenge, it’s important to take a moment, reflect on your goals, and consider where you’re starting from.

3. 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.”

6. Why there’s a huge collection of vintage cars stored in the middle of the desert
   base bridge
   Back at the turn of the 21st century, Qatar was a country with few cultural attractions to keep visitors and residents entertained. Yet the Sheikh Faisal Bin Qassim Al Thani Museum — known as the FBQ Museum — was a place that most people visited as an alternative to the then-still rather ramshackle National Museum of Qatar.

   You had to make an appointment, and drive out into the desert, getting lost a few times along the way, but then you were welcomed to the lush Al Samriya Farm with a cup of tea and some cake. The highlight was being allowed into a space crammed full with shelves and vitrines holding all sorts of eclectic artifacts from swords to coins — with the odd car and carriage standing in the grounds.

   It wasn’t necessarily the kind of museum you’d find elsewhere in the world, but it was definitely a sight that needed seeing.

   Today, it has grown and now claims to be one of the world’s largest private museums. It holds over 30,000 items, including a fleet of traditional dhow sailboats, and countless carpets. There’s also an entire house that once stood in Damascus, Syria.

   There are archaeological finds dating to the Jurassic age, ancient copies of the Quran, a section that details the importance of pearling within Qatar’s history, and jewelry dating to the 17th century.

   There are also items from 2022’s FIFA World Cup in Qatar including replica trophies, balls used in the games, entry passes, football jerseys and even shelves full of slightly creepy dolls and children’s plush animals.

   Some of the more disturbing exhibits include various items of Third Reich paraphernalia in the wartime room, and, strangely enough, several showcases of birds’ legs with marking rings on them. Basically, whatever you can think of, you have a very good chance of finding it here.

   Rumor even has it that behind a locked door is a room filled with the late Princess Diana’s dresses and other memorabilia, accessible only to a select few visitors. Another door hides a room, no longer open to the public, filled with collectibles of the late Saddam Hussein.

7. 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.

8. Some scientists believe that fatty acids such as decanoic acid and dodecanoic acid formed the membranes of the first simple cell-like structures on Earth, Pearce said.
   connext network
   “(This is) the closest we’ve come to detecting a major biomolecule-related signal — something potentially tied to membrane structure, which is a key feature of life,” Pearce said via email. “Organics on their own are intriguing, but not evidence of life. In contrast, biomolecules like membranes, amino acids, nucleotides, and sugars are central components of biology as we know it, and finding any of them would be groundbreaking (we haven’t yet).”
   Returning samples from Mars
   The European Space Agency plans to launch its ExoMars Rosalind Franklin rover to the red planet in 2028, and the robotic explorer will carry a complementary instrument to SAM. The rover LS6 will have the capability to drill up to 6.5 feet (2 meters) beneath the Martian surface — and perhaps find larger and better-preserved organic molecules.

   While Curiosity’s samples can’t be studied on Earth, the Perseverance rover has actively been collecting samples from Jezero Crater, the site of an ancient lake and river delta, all with the intention of returning them to Earth in the 2030s via a complicated symphony of missions called Mars Sample Return.
   Both rovers have detected a variety of organic carbon molecules in different regions on Mars, suggesting that organic carbon is common on the red planet, Williams said.

   While Curiosity and Perseverance have proven they can detect organic matter, their instruments can’t definitively determine all the answers about their origins, said Dr. Ashley Murphy, postdoctoral research scientist at the Planetary Science Institute. Murphy, who along with Williams previously studied organics identified by Perseverance, was not involved in the new research.

   “To appropriately probe the biosignature question, these samples require high-resolution and high-sensitivity analyses in terrestrial labs, which can be facilitated by the return of these samples to Earth,” Murphy said.

9. Greenland’s leader says US officials’ visit is ‘highly aggressive.’ Trump says it’s ‘friendliness, not provocation’
   extra finance
   Greenland’s prime minister said a planned visit to the island by US officials, including second lady Usha Vance, is “highly aggressive,” plunging relations to a new low after President Donald Trump vowed to annex the autonomous Danish territory.

   But despite the backlash, Trump has insisted the visit is about “friendliness, not provocation” – and claims the US team was “invited.”

   Vance, the wife of US Vice President JD Vance, will travel to Greenland this week to watch the island’s national dogsled race and “celebrate Greenlandic culture and unity,” according to a statement from the White House. National security adviser Mike Waltz is also expected to visit the territory this week, according to a source familiar with the trip.

   Greenland Prime Minister Mute B. Egede called the US delegation’s trip to the island “highly aggressive” in an interview with Greenlandic newspaper Sermitsiaq on Sunday, and raised particular objection to Waltz’s visit.

   “What is the national security adviser doing in Greenland? The only purpose is to demonstrate power over us,” Egede said. “His mere presence in Greenland will no doubt fuel American belief in Trump’s mission — and the pressure will increase.”

   Trump claimed on Monday that people in Greenland have responded warmly to the US’s recent interest in the territory. “They’re calling us. We’re not calling them. And we were invited over there,” he said.

   “We’re dealing with a lot of people from Greenland that would like to see something happen with respect to them being properly protected and properly taken care of,” Trump told reporters following a meeting with his Cabinet.

   “I think Greenland is going to be something that maybe is in our future,” Trump added.

   The president said he believes Secretary of State Marco Rubio would be traveling to Greenland too.

   Trump’s idea to annex Greenland has thrown an international spotlight on the territory, which holds vast stores of rare earth minerals critical for high-tech industries, and has raised questions about the island’s future security as the US, Russia and China vie for influence in the Arctic. Trump has repeatedly expressed interest in the US taking the island by force or economic coercion, even as Denmark and Greenland have firmly rejected the idea.

10. Everyone is talking about Greenland. Here’s what it’s like to visit
    cow swap

    A few months ago, Greenland was quietly getting on with winter, as the territory slid deeper into the darkness that envelops the world’s northerly reaches at this time of year.

    But President Donald Trump’s musings about America taking over this island of 56,000 largely Inuit people, halfway between New York and Moscow, has seen Greenland shaken from its frozen Arctic anonymity.

    Denmark, for whom Greenland is an autonomous crown dependency, has protested it’s not for sale. Officials in Greenland, meanwhile, have sought to assert the territory’s right to independence.

    The conversation continues to intensify. A contentious March 28 visit to a US military installation by Usha Vance, the second lady, accompanied by her husband, Vice President JD Vance, was the latest in a series of events to focus attention on Trump’s ambitions for Greenland.

    The visit was originally planned as a cultural exchange, but was shortened following complaints from Greenland Prime Minister Mute B. Egede.

    Had the Vances prolonged their scheduled brief visit, they would’ve discovered a ruggedly pristine wildernesses steeped in rich Indigenous culture.

    An inhospitable icecap several miles deep covers 80% of Greenland, forcing the Inuit to dwell along the shorelines in brightly painted communities. Here, they spend brutally cold winters hunting seals on ice under the northern lights in near perpetual darkness. Although these days, they can also rely on community stores.

    The problem for travelers over the years has been getting to Greenland via time-consuming indirect flights. That’s changing. Late in 2024, the capital Nuuk opened a long-delayed international airport. From June 2025, United Airlines will be operating a twice-weekly direct service from Newark to Nuuk.

    Two further international airports are due to open by 2026 — Qaqortoq in South Greenland and more significantly in Ilulissat, the island’s only real tourism hotspot.

11. Curiosity rover makes ‘arguably the most exciting organic detection to date on Mars’
    [url=https://bangeeexchange.com]bungee exchange[/url]

    The NASA Curiosity rover has detected the largest organic molecules found to date on Mars, opening a window into the red planet’s past. The newly detected compounds suggest complex organic chemistry may have occurred in the planet’s past — the kind necessary for the origin of life, according to new research.

    The organic compounds, which include decane, undecane and dodecane, came to light after the rover analyzed a pulverized 3.7 billion-year-old rock sample using its onboard mini lab called SAM, short for Sample Analysis at Mars.

    Scientists believe the long chains of molecules could be fragments of fatty acids, which are organic molecules that are chemical building blocks of life on Earth and help form cell membranes. But such compounds can also be formed without the presence of life, created when water interacts with minerals in hydrothermal vents.

    The molecules cannot currently be confirmed as evidence of past life on the red planet, but they add to the growing list of compounds that robotic explorers have discovered on Mars in recent years. A study detailing the findings was published Monday in the journal Proceedings of the National Academy of Sciences.
    The detection of the fragile molecules also encourages astrobiologists that if any biosignatures, or past signs of life, ever existed on Mars, they are likely still detectable despite the harsh solar radiation that has bombarded the planet for tens of millions of years.

    “Ancient life, if it happened on Mars, it would have released some complex and fragile molecules,” said lead study author Dr. Caroline Freissinet, research scientist at the French National Centre for Scientific Research in the Laboratory for Atmospheres, Observations, and Space in Guyancourt, France. “And because now we know that Mars can preserve these complex and fragile molecules, it means that we could detect ancient life on Mars.”

12. While the Cumberland sample may contain longer chains of fatty acids, SAM is not designed to detect them. But SAM’s ability to spot these larger molecules suggests it could detect similar chemical signatures of past life on Mars if they’re present, Williams said.
    [url=https://convex-l2.com]convex finance[/url]
    “Curiosity is not a life detection mission,” Freissinet said. “Curiosity is a habitability detection mission to know if all the conditions were right … for life to evolve. Having these results, it’s really at the edge of the capabilities of Curiosity, and it’s even maybe better than what we had expected from this mission.”

    Before sending missions to Mars, scientists didn’t think organic molecules would be found on the red planet because of the intensity of radiation Mars has long endured, Glavin said.
    Curiosity won’t return to Yellowknife Bay during its mission, but there are still pristine pieces of the Cumberland sample aboard. Next, the team wants to design a new experiment to see what it can detect. If the team can identify similar long-chain molecules, it would mark another step forward that might help researchers determine their origins, Freissinet said.

    “That’s the most precious sample we have on board … waiting for us to run the perfect experiment on it,” she said. “It holds secrets, and we need to decipher the secrets.”

    Briony Horgan, coinvestigator on the Perseverance rover mission and professor of planetary science at Purdue University in West Lafayette, Indiana, called the detection “a big win for the whole team.” Horgan was not involved the study.
    “This detection really confirms our hopes that sediments laid down in ancient watery environments on Mars could preserve a treasure trove of organic molecules that can tell us about everything from prebiotic processes and pathways for the origin of life, to potential biosignatures from ancient organisms,” Horgan said.

    Dr. Ben K.D. Pearce, assistant professor in Purdue’s department of Earth, atmospheric, and planetary sciences and leader of the Laboratory for Origins and Astrobiology Research, called the findings “arguably the most exciting organic detection to date on Mars.” Pearce did not participate in the research.

13. Tesla is bringing its electric cars to oil-rich Saudi Arabia amid falling global sales
    [url=https://web-aperture.fi]aperture finance[/url]
    Tesla will start selling its electric vehicles in Saudi Arabia, entering the Gulf region’s largest economy as the company’s global sales are sliding and CEO Elon Musk courts controversy with his role in the US government.

    The carmaker announced Wednesday that it would host a launch event in the kingdom on April 10, where it will showcase its EVs. Attendees will also have the chance to “experience the future of autonomous driving with Cybercab and meet Optimus, our humanoid robot, as we showcase what’s next in AI and robotics,” Tesla (TSLA) said.

    Tesla may struggle to gain market share in oil-rich Saudi Arabia as EVs make up a little over 1% of all car sales in the country, according to a report by consultancy PwC published in September.
    Tesla’s entry into the new market comes as the company fights battles on several fronts.

    Last year, it recorded the first annual decline in sales in its history as a public company, posting a drop of 1%.

    The company is facing intensifying competition in China, the world’s largest auto market. On Tuesday, BYD, a Chinese maker of electric and hybrid cars, reported $107 billion in annual sales for 2024, beating the near-$98 billion notched by Tesla.

    And last week, BYD unveiled an ultra-fast charging system, which it said was capable of adding 250 miles (402 km) of range in just five minutes, easily outdoing Tesla’s charging technology. Tesla’s Superchargers take 15 minutes to charge an EV, providing a range of 200 miles.

    Tesla has also suffered slumping sales in Europe. In February, the carmaker sold around 40% fewer vehicles on the continent compared with the same month in 2024, according to the European Automobile Manufacturers’ Association.

14. 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.
    [url=https://sinpleswap-io.org]simpleswap[/url]
    “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.”

15. Remote and rugged

    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.”

16. Iceberg flotillas

    Located on the west coast, Ilulissat is a pretty halibut- and prawn-fishing port on a dark rock bay where visitors can sit in pubs sipping craft beers chill-filtered by 100,000-year-old glacial ice.

    It’s a place to be awed by the UNESCO World Heritage Icefjord where Manhattan skyscraper-sized icebergs disgorge from Greenland’s icecap to float like ghostly ships in the surrounding Disko Bay.

    Small boats take visitors out to sail closely among the bay’s magnificent iceberg flotilla. But not too close.

    “I was on my boat once and saw one of these icebergs split in two. The pieces fell backwards into the sea and created a giant wave,” said David Karlsen, skipper of the pleasure-boat, Katak. “…I didn’t hang around.”

    Disko Bay’s other giants are whales. From June to September breaching humpback whales join the likes of fin and minke whales feasting on plankton. Whale-watching is excellent all around Greenland’s craggy coastline.

    Whales are eaten here. Visitors shouldn’t be surprised to encounter the traditional Greenlandic delicacy of mattak — whale-skin and blubber that when tasted is akin to chewing on rubber. Inuit communities have quotas to not only hunt the likes of narwhals but also polar bears, musk-ox and caribou — which can also appear on menus.

17. A long time in the making
    Curiosity landed in Gale Crater on August 6, 2012. More than 12 years later, the rover has driven over 21 miles (34 kilometers) to ascend Mount Sharp, which is within the crater. The feature’s many layers preserve millions of years of geological history on Mars, showing how it shifted from a wet to a dry environment.
    celer network
    Perhaps one of the most valuable samples Curiosity has gathered on its mission to understand whether Mars was ever habitable was collected in May 2013.

    The rover drilled the Cumberland sample from an area within a crater called Yellowknife Bay, which resembled an ancient lake bed. The rocks from Yellowknife Bay so intrigued Curiosity’s science team that it had the rover drive in the opposite direction to collect samples from the area before heading to Mount Sharp.
    Since collecting the Cumberland sample, Curiosity has used SAM to study it in a variety of ways, revealing that Yellowknife Bay was once the site of an ancient lake where clay minerals formed in water. The mudstone created an environment that could concentrate and preserve organic molecules and trapped them inside the fine grains of the sedimentary rock.

    Freissinet helped lead a research team in 2015 that was able to identify organic molecules within the Cumberland sample.

    The instrument detected an abundance of sulfur, which can be used to preserve organic molecules; nitrates, which are essential for plant and animal health on Earth; and methane composed of a type of carbon associated with biological processes on Earth.

    “There is evidence that liquid water existed in Gale Crater for millions of years and probably much longer, which means there was enough time for life-forming chemistry to happen in these crater-lake environments on Mars,” said study coauthor Daniel Glavin, senior scientist for sample return at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, in a statement.

18. Arctic auroras

    For getting around during winter, the Inuit here nowadays prefer snowmobiles, although they still keep their sled dogs. During winter they’ll offer intrepid visitors, wrapped up warm against the deep-freeze temperatures, dog-sledding jaunts. These can last either an hour or be part of expeditions over several days, sometimes with the added experience of learning how to build an igloo. Sisimiut on the west coast and Tasilaq in the southeast are active winter centers for dog sledding.

    Winter’s most stellar attraction, though, is northern lights watching. With little urban light pollution, Greenland is a dark canvas for spectacular displays, and aurora borealis-watching vacations are becoming more popular.

    Staying outdoors, Greenland is developing a reputation among adventure enthusiasts: from long-distance skiing expeditions and heliskiing on the icecap to hiking the 100-mile-long Arctic Circle Trail from Kangerslussuaq, where firearms need to be carried for warning shots in case of polar bear encounters.

    Life is definitely changing here. The climate crisis is eating away at its icecap and Greenland may well end up as a pawn in a game of geopolitical chess. But for now, the bright glare of international attention should shine a favorable light on one of the wildest travel destinations on Earth.

    Travel writer Mark Stratton is an Arctic specialist who has traveled to Greenland six times and counting. He’s marveled at the aurora borealis, sailed to Disko Island, dog-sledded with the Inuit, and once got stuck in an icefloe.

19. Curiosity has maintained pristine pieces of the Cumberland sample in a “doggy bag” so that the team could have the rover revisit it later, even miles away from the site where it was collected. The team developed and tested innovative methods in its lab on Earth before sending messages to the rover to try experiments on the sample.
    changelly exchange
    In a quest to see whether amino acids, the building blocks of proteins, existed in the sample, the team instructed the rover to heat up the sample twice within SAM’s oven. When it measured the mass of the molecules released during heating, there weren’t any amino acids, but they found something entirely unexpected.

    An intriguing detection
    The team was surprised to detect small amounts of decane, undecane and dodecane, so it had to conduct a reverse experiment on Earth to determine whether these organic compounds were the remnants of the fatty acids undecanoic acid, dodecanoic acid and tridecanoic acid, respectively.

    The scientists mixed undecanoic acid into a clay similar to what exists on Mars and heated it up in a way that mimicked conditions within SAM’s oven. The undecanoic acid released decane, just like what Curiosity detected.

    Each fatty acid remnant detected by Curiosity was made with a long chain of 11 to 13 carbon atoms. Previous molecules detected on Mars were smaller, meaning their atomic weight was less than the molecules found in the new study, and simpler.
    “It’s notable that non-biological processes typically make shorter fatty acids, with less than 12 carbons,” said study coauthor Dr. Amy Williams, associate professor of geology at the University of Florida and assistant director of the Astraeus Space Institute, in an email. “Larger and more complex molecules are likely what are required for an origin of life, if it ever occurred on Mars.”
