  Curiosity rover makes ‘arguably the most exciting organic detection to date on Mars’
  bungee exchange
  
  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.”

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

  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.

  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.

  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.

  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.

  “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%.

  President Donald Trump on Thursday blamed the Federal Aviation Administration’s “diversity push” in part for the plane collision that killed 67 people in Washington, DC. But DEI backers, including most top US companies, believe a push for diversity has been good for their businesses.
  
  Trump did not cite any evidence for how efforts to hire more minorities, people with disabilities and other groups less represented in American workforces led to the crash, saying “it just could have been” and that he had “common sense.” But Trump criticized the FAA’s effort to recruit people with disabilities during Joe Biden’s administration, even though the FAA’s Aviation Safety Workforce Plan for the 2020-2029 period, issued under Trump’s first administration, promoted and supported “the hiring of people with disabilities and targeted disabilities.”

  It’s not the first time opponents of diversity, equity and inclusion initiatives, or DEI, have said they can kill people. “DEI means people DIE,” Elon Musk said after the California wildfires, criticizing the Los Angeles Fire Department and city and state officials for their efforts to advance diversity in their workforces.

  ‘We don’t want the American Dream for our kids’: Why this couple left the US for Ecuador with their children four years ago
  адвокат Запоріжжя
  They’d never even visited Ecuador before, but Brittany and Blake Bowen, from the United States, decided to move to the South American country in 2021 to give their four children a completely different upbringing.
  
  The Bowens, who were previously based in the state of Washington, have been living in Loja, a small city based in the southern section of the Andes Mountains, ever since, and say that they are in it for the long haul.
  
  “We love this little country,” Brittany tells CNN Travel. “We hope that maybe we’ll have grandkids here one day.”
  Before the move, the couple, who’ve been married for nearly 17 years, say that they were becoming increasingly concerned about the pressures placed on children by “modern American society” and wanted to try something new.
  
  “We did not like what we’d seen develop over the course of the last couple decades…” adds Brittany, explaining that they felt that young people in the United States were becoming “more isolated.”
  
  “We weren’t confident that our kids would enjoy the same sort of potential trajectory that previous generations had shared.
  
  “And the more we considered things like that, the more we wondered, ‘Is that even what we want? Do we even want them to be on a fast track to the American Dream?”
  
  The couple were also frustrated with living what they describe as the “standard American life.”
  
  “Long commutes and never enough money,” says Blake. “All those usual problems… I was working in a career that was very time consuming, and took me away from home a lot. So we didn’t want that anymore.”
  
  So why did they choose Ecuador as their “new home”?

  “You get some of me but not tomorrow as they want me in as soon as I can make it happen. This is the one time when they say jump and I ask how high due the financial gains the company could benefit from and it being important enough for the client to appear in person.”
  
  “Well I get an extra night of you at least! I wonder what we could do with that? Meantime, what about food? I am starving and delicious as it was a second breakfast is not quite enough to replenish me!”
  
  “Well get something on and we’ll sort that out first.”
  
  We drove into town and decided that a daytime visit to Charlie’s was going to be the answer. I parked in the bar lot and Elise dashed in to change into something more appropriate, jeans and a t-shirt along with her biker jacket but keeping her Converses on.
  
  Walking down to the restaurant was different from the middle of the night visits as the streets were bustling and all of the shops and outlets were open.
  
  Reaching Charlie’s we entered the front door and sat in a booth near the window. A beautiful young American Chinese girl came,smiled and said hello to Elise and gave us menus and asked if we wanted drinks in the meantime.
  
  "No thanks Lin just a pot of Jasmine tea for us please." Lin went back to the kitchen area. “No booze for me today as I will have to work in the bar so it is just tea for me.”
  
  Not in a drinking mood either, I agreed with her."
