    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. convex finance “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.

    Tesla is bringing its electric cars to oil-rich Saudi Arabia amid falling global sales aperture finance Tesla will start selling its electric vehicles in Saudi Arabia entering the Gulf region’s largest economy as the company’s global sales are sliding and CEO Elon Musk courts controversy with his role in the US government. The carmaker announced Wednesday that it would host a launch event in the kingdom on April 10 where it will showcase its EVs. Attendees will also have the chance to “experience the future of autonomous driving with Cybercab and meet Optimus our humanoid robot as we showcase what’s next in AI and robotics” Tesla TSLA said. Tesla may struggle to gain market share in oil-rich Saudi Arabia as EVs make up a little over 1 of all car sales in the country according to a report by consultancy PwC published in September. Tesla’s entry into the new market comes as the company fights battles on several fronts. Last year it recorded the first annual decline in sales in its history as a public company posting a drop of 1. The company is facing intensifying competition in China the world’s largest auto market. On Tuesday BYD a Chinese maker of electric and hybrid cars reported 107 billion in annual sales for 2024 beating the near-98 billion notched by Tesla. And last week BYD unveiled an ultra-fast charging system which it said was capable of adding 250 miles 402 km of range in just five minutes easily outdoing Tesla’s charging technology. Tesla’s Superchargers take 15 minutes to charge an EV providing a range of 200 miles. Tesla has also suffered slumping sales in Europe. In February the carmaker sold around 40 fewer vehicles on the continent compared with the same month in 2024 according to the European Automobile Manufacturers’ Association.

    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.

    Why axolotls seem to be everywhere — except in the one lake they call home жесток порно видео 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.” смотреть порно жесток 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.”
