Curiosity rover makes ‘arguably the most exciting organic detection to date on Mars’
[url=https://bangeeexchange.com]bungee exchange[/url]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.”
Why there’s a huge collection of vintage cars stored in the middle of the desert

Back at the turn of the 21st century, Qatar was a country with few cultural attractions to keep visitors and residents entertained. Yet the Sheikh Faisal Bin Qassim Al Thani Museum — known as the FBQ Museum — was a place that most people visited as an alternative to the then-still rather ramshackle National Museum of Qatar.You had to make an appointment, and drive out into the desert, getting lost a few times along the way, but then you were welcomed to the lush Al Samriya Farm with a cup of tea and some cake. The highlight was being allowed into a space crammed full with shelves and vitrines holding all sorts of eclectic artifacts from swords to coins — with the odd car and carriage standing in the grounds.
It wasn’t necessarily the kind of museum you’d find elsewhere in the world, but it was definitely a sight that needed seeing.
Today, it has grown and now claims to be one of the world’s largest private museums. It holds over 30,000 items, including a fleet of traditional dhow sailboats, and countless carpets. There’s also an entire house that once stood in Damascus, Syria.
There are archaeological finds dating to the Jurassic age, ancient copies of the Quran, a section that details the importance of pearling within Qatar’s history, and jewelry dating to the 17th century.
There are also items from 2022’s FIFA World Cup in Qatar including replica trophies, balls used in the games, entry passes, football jerseys and even shelves full of slightly creepy dolls and children’s plush animals.
Some of the more disturbing exhibits include various items of Third Reich paraphernalia in the wartime room, and, strangely enough, several showcases of birds’ legs with marking rings on them. Basically, whatever you can think of, you have a very good chance of finding it here.
Rumor even has it that behind a locked door is a room filled with the late Princess Diana’s dresses and other memorabilia, accessible only to a select few visitors. Another door hides a room, no longer open to the public, filled with collectibles of the late Saddam Hussein.
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.
Arctic auroras

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.
Wellness perfectionism doesn’t exist. Focus on these sustainable habits
[url=https://susisvvap.com]sushiswap exchange[/url]
ou’re scrolling through your phone when you stumble upon the next viral trend: an influencer claiming that following their incredibly strict diet will help you achieve their jaw-dropping physique. Or you see a fresh-faced runner swearing you can run a marathon without any training — just like they did.Whether or not you’re actively searching for wellness advice, it’s nearly impossible to avoid hearing about the latest health craze making bold guarantees of transformation.
As you wonder if these claims hold any truth, you might also question why people often feel motivated to dive into intense challenges — when seemingly simple habits, such as getting enough sleep or eating more vegetables, often feel much harder to tackle.
Many of us are drawn to these extreme challenges because we’re craving radical change, hoping it will help prove something to ourselves or to others, experts say.
“We always see these kinds of challenges as opportunities for growth, particularly if we’re in a phase of our life where we’ve let ourselves go,” said Dr. Thomas Curran, associate professor of psychology at the London School of Economics and Political Science and an expert on perfectionism. “Maybe we feel that we need to be healthier, or we just had a breakup or (major) life event.”
With social media amplifying these movements, it’s easy to see why people are increasingly drawn to the idea of achieving the “perfect” version of themselves. But before jumping into a new wellness challenge, it’s important to take a moment, reflect on your goals, and consider where you’re starting from.New design revealed for Airbus hydrogen plane
[url=https://v2-renzo.net]renzo[/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.

Scientists redid an experiment that showed how life on Earth could have started. They found a new possibility
[url=https://web-safepal.com]safepal[/url]
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.
A tiny rainforest country is growing into a petrostate. A US oil company could reap the biggest rewards
[url=https://svveli.net]swell[/url]
Guyana’s destiny changed in 2015. US fossil fuel giant Exxon discovered nearly 11 billion barrels of oil in the deep water off the coast of this tiny, rainforested country.It was one of the most spectacular oil discoveries of recent decades. By 2019, Exxon and its partners, US oil company Hess and China-headquartered CNOOC, had started producing the fossil fuel.? They now pump around 650,000 barrels of oil a day, with plans to more than double this to 1.3 million by 2027.
Guyana now has the world’s highest expected oil production growth through 2035.
This country — sandwiched between Brazil, Venezuela and Suriname — has been hailed as a climate champion for the lush, well-preserved forests that carpet nearly 90% of its land. It is on the path to becoming a petrostate at the same time as the impacts of the fossil fuel-driven climate crisis escalate.
While the government says environmental protection and an oil industry can go hand-in-hand, and low-income countries must be allowed to exploit their own resources, critics say it’s a dangerous path in a warming world, and the benefits may ultimately skew toward Exxon — not Guyana.
Mist and microlightning

To recreate a scenario that may have produced Earth’s first organic molecules, researchers built upon experiments from 1953 when American chemists Stanley Miller and Harold Urey concocted a gas mixture mimicking the atmosphere of ancient Earth. Miller and Urey combined ammonia (NH3), methane (CH4), hydrogen (H2) and water, enclosed their “atmosphere” inside a glass sphere and jolted it with electricity, producing simple amino acids containing carbon and nitrogen. The Miller-Urey experiment, as it is now known, supported the scientific theory of abiogenesis: that life could emerge from nonliving molecules.
For the new study, scientists revisited the 1953 experiments but directed their attention toward electrical activity on a smaller scale, said senior study author Dr. Richard Zare, the Marguerite Blake Wilbur Professor of Natural Science and professor of chemistry at Stanford University in California. Zare and his colleagues looked at electricity exchange between charged water droplets measuring between 1 micron and 20 microns in diameter. (The width of a human hair is 100 microns.)“The big droplets are positively charged. The little droplets are negatively charged,” Zare told CNN. “When droplets that have opposite charges are close together, electrons can jump from the negatively charged droplet to the positively charged droplet.”
The researchers mixed ammonia, carbon dioxide, methane and nitrogen in a glass bulb, then sprayed the gases with water mist, using a high-speed camera to capture faint flashes of microlightning in the vapor. When they examined the bulb’s contents, they found organic molecules with carbon-nitrogen bonds. These included the amino acid glycine and uracil, a nucleotide base in RNA.“We discovered no new chemistry; we have actually reproduced all the chemistry that Miller and Urey did in 1953,” Zare said. Nor did the team discover new physics, he added — the experiments were based on known principles of electrostatics.
“What we have done, for the first time, is we have seen that little droplets, when they’re formed from water, actually emit light and get this spark,” Zare said. “That’s new. And that spark causes all types of chemical transformations.”
‘White Lotus’ villain Jon Gries reveals the true crimes that inspired his twisty take on Greg/Gary
[url=https://fixedf1oat.org]fixedfloat exchange[/url]
When Season 3 of “The White Lotus” premiered last month, the shock was palpable when returning character Belinda recognized a familiar face at the resort in Thailand: Greg Hunt, the wily suitor of the late Tanya McQuoid.As the season has unfolded, Greg (played by Jon Gries) has emerged as an antagonist, particularly after Belinda dove into the investigation surrounding Tanya’s death and learned that Greg, who now goes by Gary, evaded questioning by authorities.
On a show famous for reinventing itself, the same has been asked of the actor, who says that playing the ever-shifting character has been a welcome challenge and, like “White Lotus” itself, full of twists.
“In the beginning, I totally played him for a guy who was, you know, on his last legs,” Gries said in a recent interview with CNN, referencing Greg’s very apparent ill health in the first season of “White Lotus,” which premiered to rave reviews in summer 2021. He added: “When you play a character, you want to find his empathetic side, and you want to understand where they came from, and what got them to where they are.”
But when he was contacted by creator Mike White about appearing in Season 2, Gries realized he would have to adjust his framing of Greg, despite having previously imagined a “comprehensive history” for him on his own.
“(White) said, ‘I’m writing it right now, and I’m writing you, and I just need to know here and now: If you’re in, I’ll continue writing. If not, I’ll stop,’” Gries recalled.
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.
[url=https://hop-excharge.com]hop exchange[/url]
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.
Tyler O’Neill hits record-extending sixth straight Opening Day home run
[url=https://orbiferfi.com]orbiter finance[/url]
For six seasons in a row, Tyler O’Neill has homered on MLB Opening Day.Making his debut for the Baltimore Orioles on Thursday, O’Neill started the season with his record-extending sixth straight home run on Opening Day during his team’s 12-2 win against the Toronto Blue Jays.
No other player has homered on more than four consecutive Opening Days, with the 29-year-old outfielder’s three-run shot sending the Orioles into a 5-0 lead at the top of the third at Rogers Centre.
Todd Hundley (1994-97), Gary Carter (1977-80) and Yogi Berra (1955-58) all hit four consecutive home runs on Opening Day, while the Major League Baseball record for the total number of Opening Day home runs is held jointly by Adam Dunn, Ken Griffey Jr. and Frank Robinson on eight.“I’m just not trying to make too much of it,” O’Neill told reporters about his streak. “I’m just trying to go out, have a good first at-bat and see what the game gives me from there.
“Obviously, I understand what’s going on, but it’s not like I’m going out there trying to do anything crazy.”
O’Neill, who signed a three-year, $49.5 million contract to join Baltimore from the Boston Red Sox in the offseason, finished three-for-three with three RBIs and two walks against the Blue Jays.
“It’s a little different when the lights turn on and you’ve got to show up, so it was really cool to see all the guys show up today,” he said. “We got after it out there.”
While the first two games of the MLB regular season took place between the Chicago Cubs and Los Angeles Dodgers in Tokyo last week, Thursday marked the first official day of the season in the United States.
The voice of ‘White Lotus’ star Walton Goggins is the lullaby we didn’t know we needed
[url=https://jumper-ex.org]jumper exchange[/url]
While his “White Lotus” character Rick has been the source of some stress this season, Walton Goggins is here to soothe us into a state of dreamy sleep to make up for it.The actor has partnered with relaxation and meditation app Calm for one of their famed Sleep Stories, lending his smoky voice to a fable titled “The Yard Sale.”
Goggins announced the Sleep Story on his verified Instagram on Tuesday, writing, “A friend once said to me the first question you ask someone shouldn’t be, ‘How are you?’ but rather, ‘How did you sleep last night?’ I agree.”
The post included an excerpt from the story, in which Goggins is heard languidly instructing listeners to relax their bodies and get into bed. “You could even climb into a hammock,” he added. “I wouldn’t do that because I’ve never gracefully got in or out of one.”
In the caption, the actor also wrote that he “wanted to create a Sleep Story that feels dreamlike, helping people slow their minds down by wandering through a yard sale (which happens to be one of my favorite things to do), uncovering hidden treasures.”
“It’s the Walton Goggins version of counting sheep. I hope you enjoy,” he added.
Other celebrities who have read bedtime stories in the hopes of putting audiences to sleep include Dolly Parton and the late Jimmy Stewart, whose voice was featured in a Calm Christmas Sleep Story in 2023 thanks to generative AI technology.
Goggins currently stars on “The White Lotus,” where his character is often the most stressed out and tortured of the ensemble, at one point setting a slew of snakes free.
Aged 15, New Zealander Sam Ruthe has already run a four-minute mile. He would ‘love to try and qualify’ for the 2028 Olympics
[url=https://parasvvap.com]paraswap[/url]Sam Ruthe had the eyes of thousands on him when he stepped onto a running track in Auckland just over a week ago.
Undaunted by the occasion, Ruthe went on to become the first 15-year-old to run a sub-four-minute mile, even managing a nonchalant shrug of the shoulders as he crossed the finish line.
The race was almost entirely engineered for the high school student to break the fabled four-minute barrier – a feat first achieved by Roger Bannister more than 70 years ago – but the weight of running history was a burden that Ruthe seemed to bear lightly.
The first three laps, he later said in a video documenting the race, “felt pretty comfortable – nothing too crazy.”
Perhaps the most intimidating part of his achievement occurred when Ruthe returned to school the next day, only to be immediately called into the principal’s office.
“He’s like, ‘Alright, so you’re gonna have to go up on stage and we’ll get the whole school to clap you,’” Ruthe tells CNN Sports’ Patrick Snell. “It was really scary, actually. I headed into class and everyone thought I was famous.”
It’s easy to forget, given his history-making performance last week, that Ruthe is like most other 15-year-olds in New Zealand. He goes to school, spends time with his friends, and helps with chores around the house.
He also just happens to be one of the most exciting middle-distance runners on the planet, one of the latest star athletes to emerge from sports-mad New Zealand.
