  New design revealed for Airbus hydrogen plane
  renzo
  
  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.

  Josh Giddey hits halfcourt buzzer-beater over LeBron James to cap wild finale as the Bulls stun the Lakers
  quickswap exchange
  Josh Giddey hit a game-winning, halfcourt buzzer-beater over LeBron James as the Chicago Bulls stunned the Los Angeles Lakers in one of the wildest endings to an NBA game you are ever likely to see.
  
  Trailing 115-110 with 12.6 seconds remaining, Giddey’s inbound pass found Nikola Vucevic, who pushed the ball to a wide-open Patrick Williams for a corner three-pointer.
  
  James then fluffed the Lakers inbound pass from the baseline, allowing Giddey to steal the ball and find Coby White for a second Bulls triple in quick succession to put Chicago up 116-115 with 6.1 seconds remaining.
  Austin Reaves then made a driving layup to put the Lakers ahead 117-116 with 3.3 seconds left, but the game wasn’t done yet.
  
  With no timeouts remaining, Giddey inbounded the ball to Williams from the baseline, got the pass back, took one dribble and launched a shot from beyond halfcourt.
  
  Supporters in the stands seemed frozen in anticipation as the ball sailed through the air, and the United Center then erupted as it fell through the net. After the dramatic win, Giddey found himself being swarmed by his teammates.
  
  “Special moment to do it with these guys, this team,” Giddey said, per ESPN. “We’ve shown over the last month to six weeks that we can beat anybody. The way we play the game, I think it wears people down.
  
  “We get up and down. We run. We put heat on them to get back. A lot of veteran teams don’t particularly want to get back and play in transition.”
  
  Giddey later told the Bulls broadcast that he’d “never made a game-winner before.”
  
  The ending capped an incredible couple of games for the Lakers, who had themselves won their last game against the Indiana Pacers on Wednesday with a buzzer-beating tip-in from James.

  Water and life
  stargate finance
  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.
  
  Researchers identified salt minerals in the Bennu samples that were deposited as a result of brine evaporation from the asteroid’s parent body. In particular, they found a number of sodium salts, such as the needles of hydrated sodium carbonate highlighted in purple in this false-colored image – salts that could easily have been compromised if the samples had been exposed to water in Earth’s atmosphere.

  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.”

  Some scientists believe that fatty acids such as decanoic acid and dodecanoic acid formed the membranes of the first simple cell-like structures on Earth, Pearce said.
  connext bridge
  “(This is) the closest we’ve come to detecting a major biomolecule-related signal — something potentially tied to membrane structure, which is a key feature of life,” Pearce said via email. “Organics on their own are intriguing, but not evidence of life. In contrast, biomolecules like membranes, amino acids, nucleotides, and sugars are central components of biology as we know it, and finding any of them would be groundbreaking (we haven’t yet).”
  Returning samples from Mars
  The European Space Agency plans to launch its ExoMars Rosalind Franklin rover to the red planet in 2028, and the robotic explorer will carry a complementary instrument to SAM. The rover LS6 will have the capability to drill up to 6.5 feet (2 meters) beneath the Martian surface — and perhaps find larger and better-preserved organic molecules.
  
  While Curiosity’s samples can’t be studied on Earth, the Perseverance rover has actively been collecting samples from Jezero Crater, the site of an ancient lake and river delta, all with the intention of returning them to Earth in the 2030s via a complicated symphony of missions called Mars Sample Return.
  Both rovers have detected a variety of organic carbon molecules in different regions on Mars, suggesting that organic carbon is common on the red planet, Williams said.
  
  While Curiosity and Perseverance have proven they can detect organic matter, their instruments can’t definitively determine all the answers about their origins, said Dr. Ashley Murphy, postdoctoral research scientist at the Planetary Science Institute. Murphy, who along with Williams previously studied organics identified by Perseverance, was not involved in the new research.
  
  “To appropriately probe the biosignature question, these samples require high-resolution and high-sensitivity analyses in terrestrial labs, which can be facilitated by the return of these samples to Earth,” Murphy said.

  Wellness perfectionism doesn’t exist. Focus on these sustainable habits
  sushiswap
  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.

  Why axolotls seem to be everywhere — except in the one lake they call home
  порно анальный секс
  
  Scientist Dr. Randal Voss gets the occasional reminder that he’s working with a kind of superstar. When he does outreach events with his laboratory, he encounters people who are keen to meet his research subjects: aquatic salamanders called axolotls.
  
  The amphibians’ fans tell Voss that they know the animals from the internet, or from caricatures or stuffed animals, exclaiming, “‘They’re so adorable, we love them,’” said Voss, a professor of neuroscience at the University of Kentucky College of Medicine. “People are drawn to them.”
  
  Take one look at an axolotl, and it’s easy to see why it’s so popular. With their wide eyes, upturned mouths and pastel pink coloring, axolotls look cheerful and vaguely Muppet-like.
  
  They’ve skyrocketed in pop culture fame, in part thanks to the addition of axolotls to the video game Minecraft in 2021. These unusual salamanders are now found everywhere from Girl Scout patches to hot water bottles. But there’s more to axolotls than meets the eye: Their story is one of scientific discovery, exploitation of the natural world, and the work to rebuild humans’ connection with nature.
  
  A scientific mystery
  Axolotl is a word from Nahuatl, the Indigenous Mexican language spoken by the Aztecs and an estimated 1.5 million people today. The animals are named for the Aztec god Xolotl, who was said to transform into a salamander. The original Nahuatl pronunciation is “AH-show-LOAT”; in English, “ACK-suh-LAHT-uhl” is commonly used.
  Axolotls are members of a class of animals called amphibians, which also includes frogs. Amphibians lay their jelly-like eggs in water, and the eggs hatch into water-dwelling larval states. (In frogs, these larvae are called tadpoles.)
  
  Most amphibians, once they reach adulthood, are able to move to land. Since they breathe, in part, by absorbing oxygen through their moist skin, they tend to stay near water.
  
  Axolotls, however, never complete the metamorphosis to a land-dwelling adult form and spend their whole lives in the water.
  
  “They maintain their juvenile look throughout the course of their life,” Voss said. “They’re teenagers, at least in appearance, until they die.”

  Axolotl problems
  As Mexico City grew and became more industrialized, the need for water brought pumps and pipes to the lake, and eventually, “it was like a bad, smelly pond with rotten water,” Zambrano said. “All of our aquatic animals suffer with bad water quality, but amphibians suffer more because they have to breathe with the skin.”
  гей член
  To add to the axolotls’ problems, invasive fish species such as carp and tilapia were introduced to the lake, where they feed on axolotl eggs. And a 1985 earthquake in Mexico City displaced thousands of people, who found new homes in the area around the lake, further contributing to the destruction of the axolotls’ habitat.
  
  These combined threats have devastated axolotl populations. According to the International Union for Conservation of Nature, there are fewer than 100 adult axolotls left in the wild. The species is considered critically endangered.
  While the wild axolotls of Lake Xochimilco have dwindled to near-extinction, countless axolotls have been bred for scientific laboratories and the pet trade. “The axolotl essentially helped establish the field of experimental zoology,” Voss said.
  
  In 1864, a French army officer brought live axolotls back to Europe, where scientists were surprised to learn that the seemingly juvenile aquatic salamanders were capable of reproduction. Since then, scientists around the world have studied axolotls and their DNA to learn about the salamanders’ unusual metamorphosis (or lack thereof) as well as their ability to regrow injured body parts.
  In addition to their role in labs, axolotls have become popular in the exotic pet trade (though they are illegal to own in California, Maine, New Jersey and Washington, DC). However, the axolotls you might find at a pet shop are different from their wild relatives in Lake Xochimilco. Most wild axolotls are a dark grayish brown. The famous pink axolotls, as well as other color variants such as white, blue, yellow and black, are genetic anomalies that are rare in the wild but selectively bred for in the pet trade.
  
  What’s more, “most of the animals in the pet trade have a very small genetic variance,” Zambrano said. Pet axolotls tend to be inbred and lack the wide flow of different genes that makes up a healthy population in the wild. That means that the axolotl extinction crisis can’t simply be solved by dumping pet axolotls into Lake Xochimilco. (Plus, the pet axolotls likely wouldn’t fare well with the poor habitat conditions in the lake.)
  
  Fame and misfortune
  The difficulties that axolotls face in the wild are almost diametrically opposed to the fame they’ve found in recent years. Axolotls have captured the human imagination for centuries, as evidenced by their roles in Aztec religion and stories, but the early 21st century seems to be a high point for them. An axolotl graces the 50 peso bill. There are axolotl-inspired Pokemon, and Reddit commenters have noted that the character Toothless from the “How to Train Your Dragon” movie series is distinctly axolotl-like.
  
  The introduction of axolotls to Minecraft in 2021 neatly mapped onto an uptick in Google searches for the animals, and social media makes it easy for people to gain access to photos and videos of the salamanders, particularly the photogenic pink ones often kept as pets.
  
  The axolotl pet trade probably doesn’t directly harm the wild populations since wild salamanders aren’t being poached or taken from Lake Xochimilco. However, Zambrano said, axolotls’ ubiquity in pop culture and pet stores might make people assume that because axolotls “live in all the tanks around the world, they are not in danger.”
