Guest Jasoninser Posted March 30 Report Arctic auroras [url=https://efhenna.org]ethena[/url] 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. Quote

Guest Davidtralm Posted March 30 Report 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://comvexfimance.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.

Guest FreddieGed Posted March 30 Report 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. [url=https://connexf.net]connext network[/url] “(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.

Guest JosephNus Posted March 30 Report Greenland’s leader says US officials’ visit is ‘highly aggressive.’ Trump says it’s ‘friendliness, not provocation’ [url=https://extrolfi.org]extra fi[/url] 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. Quote

Guest EdwardTop Posted March 30 Report New design revealed for Airbus hydrogen plane [url=https://beefy-f1.com]beefy fi[/url] 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. Quote
Guest Roberticorn Posted March 30 Report Family affair [url=https://rhimo-fi.com]rhino fi[/url] Americans Brittany and Blake Bowen had never even been to Ecuador when in 2021 they decided to move to the South American country with their four children. Tired of “long commutes and never enough money” in the US, the Bowens say they love their new Ecuadorian life. “We hope that maybe we’ll have grandkids here one day.” Erik and Erin Eagleman moved to Switzerland from Wisconsin with their three children in 2023. “It feels safe here,” they tell CNN of their new outdoorsy lifestyle in Basel, close to the borders with France and Germany. Their youngest daughter even walks to elementary school by herself. For adventures with your own family, be it weekend breaks or something longer-term, our partners at CNN Underscored, a product review and recommendations guide owned by CNN, have this roundup of the best kids’ luggage sets and bags. Starry, starry nights For close to 100 years, Michelin stars have been a sign of culinary excellence, awarded only to the great and good. Georges Blanc, the world’s longest-standing Michelin-starred restaurant, has boasted a three-star rating since 1981, but this month the Michelin guide announced that the restaurant in eastern France was losing a star. More culinary reputations were enhanced this week, when Asia’s 50 best restaurants for 2025 were revealed. The winner was a Bangkok restaurant which is no stranger to garlands, while second and third place went to two Hong Kong eateries. You don’t need to go to a heaving metropolis for excellent food, however. A 200-year-old cottage on a remote stretch of Ireland’s Atlantic coast has been given a Michelin star. At the time of awarding, Michelin called it “surely the most rural” of its newest winners. Quote

Guest Kennethsar Posted March 30 Report Challenging our perceptions of ‘perfection’ [url=https://trodrerjoexzy.fi]traderjoexyz[/url] 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.
