1. 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.

   “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.

2. 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.”

3. 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.

4. 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.

5. Of course, he said yes to coming back to the series, which eventually required him to live in Italy for a few months for filming.

   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.

6. Critics say this power imbalance is clear in the 2016 contract Guyana signed with Exxon. Under the agreement, Exxon keeps 75% of everything it makes from its oil operations in Guyana, with the remaining 25% shared equally between the company and the government, which also takes a 2% royalty.

   “It was a bad deal,” Ali said in the BBC interview, but he has rejected the idea of unilaterally changing the agreement, which was signed by the previous government. He says the next contract with Exxon will be on different terms.

   An Exxon spokesperson said the contract is “globally competitive for countries at a similar stage of exploration” and said Guyana is averaging $1 billion a year in “oil profits.”

   Exxon has also faced a number of lawsuits over its potential environmental impact, many filed by Melinda Janki, a Guyanese international lawyer, who drafted the country’s Environmental Protection Act back in the 1990s.

   A big victory for Guyana’s people and environment came in 2023, when the court ruled Exxon should have unlimited liability for the costs of any oil spill. Exxon has since appealed the ruling and has posted a $2 billion guarantee while it awaits the appeal outcome.
   Exxon said this commitment supplements “its robust balance sheets … and the insurance policies they already had in place.” Janki says this isn’t enough. Offshore oil spills can be extremely expensive to deal with, the 2010 Deepwater Horizon spill cost nearly $70 billion to clean up.

   The push and pull between those who say oil offers Guyana a brighter future and those who fear the industry’s impact will continue.

   Exxon said it’s had a positive impact on the country, including employing more than 6,200 people, investing more than $2 billion with local Guyanese businesses since 2015 and spending more than $43 million on community projects.

7. Water and life
   Eth Mixer
   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.
   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.”
