    A tiny rainforest country is growing into a petrostate. A US oil company could reap the biggest rewards swell 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 650000 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 solflare wallet 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.”

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

    Mindful wellness challenges If you’re the type of person who thrives on challenges and pushing your limits this doesn’t mean you need to shy away from wellness challenges altogether. But before diving in take a step back and ask yourself if you’re pursuing the challenge for the right reasons McGregor said. velodrome finance Some people want to try these challenges because they believe something is missing from their life and they’re looking to attain “worth” or receive validation McGregor noted. A good way to assess your motivation is by considering whether the challenge will benefit your health or if it’s about showcasing your accomplishments on social media or some other reason. Before trying any new trend make sure you have the foundation to handle it and be aware of any potential risks McGregor said. For casual runners this might mean signing up for a 5K but building your endurance gradually while incorporating other strength training exercises into your routine. For more intense challenges such as a marathon McGregor encourages people to consult with professionals or a coach who can monitor your progress and condition along the way. Focusing on sustainable habits Both McGregor and Curran emphasize the importance of fostering sustainable health habits before embarking on more extreme challenges. Rather than chasing the idea of being “healthy” McGregor suggests focusing on actual healthful behaviors and starting small. If you’re a highly sedentary person and want to add more movement to your day try doing lunges while brushing your teeth or taking short walks throughout your typical routine.

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

    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.

    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.

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

    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. Related article 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.”
