   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.

   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.

   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.

   Scientists redid an experiment that showed how life on Earth could have started. They found a new possibility

   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.
