    Remote and rugged eigenlayer 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 3500 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.”

    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 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.”

    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. convex finance “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.

    Tesla is bringing its electric cars to oil-rich Saudi Arabia amid falling global sales aperture finance 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.

    Arctic auroras ethena 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.

    Trailer trucks queue to cross into the United States at the Otay Mesa Port of Entry in Tijuana Mexico November 27 2024. Jorge Duenes/Reuters New York CNN — blacksprut площадка Since President Donald Trump won the election in November businesses across the globe have been bracing for higher tariffs — a key Day One promise the president made. But over a week into his presidency Trump has yet to enact any new tariffs. блэк СЃРїСЂСѓС‚ That could change come 11:59 p.m. ET on Saturday — the deadline Trump set for when he says he will slap 25 tariffs on all Mexican and Canadian goods and a 10 tariff on all Chinese goods. The tariffs he said will be imposed as a way of punishing the three nations which Trump claims are responsible for helping people enter the country illegally and supplying fentanyl consumed in the US. Speaking to reporters from the Oval Office on Thursday Trump said he meant business especially with his tariff threats on Mexico and Canada. White House Press Secretary Karoline Leavitt also confirmed on Friday that Trump will levy the 10 tariff on China on Saturday. блекспрут Should these threats be believed? Yes and no said Trump’s former Commerce Secretary Wilbur Ross. blacksprut ссылка https://blacksprut2rprrt3aoigwh7zftiprzqyqynzz2eiimmwmykw7wkpyad.net The threat of blanket tariffs is likely being overstated Ross said in an interview with CNN. “There probably will be exclusions because there are some goods that just are not made here will not be made here and therefore there’s no particular point putting tariffs on.” Ross who was one of a handful of initial cabinet members in Trump’s first administration who kept their position for the entire four-year term said he advocated for such exclusions when he advised Trump on tariff policies. blacksprut
