A tiny rainforest country is growing into a petrostate. A US oil company could reap the biggest rewards <a href=https://swell-net.com>swell network</a> 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 <a href=https://solffare.com>solflare</a> 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.”

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. <a href=https://ve1odrome.net>velodrome finance</a> 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.

Scientists redid an experiment that showed how life on Earth could have started. They found a new possibility <a href=https://web-safepal.com>safepal</a> 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.

Family affair <a href=https://rhimo-fi.org>rhino fi</a> Americans Brittany and Blake Bowen had never even been to Ecuador when in 2021 they decided to move to the South American country with their four children. Tired of “long commutes and never enough money” in the US, the Bowens say they love their new Ecuadorian life. “We hope that maybe we’ll have grandkids here one day.” Erik and Erin Eagleman moved to Switzerland from Wisconsin with their three children in 2023. “It feels safe here,” they tell CNN of their new outdoorsy lifestyle in Basel, close to the borders with France and Germany. Their youngest daughter even walks to elementary school by herself. For adventures with your own family, be it weekend breaks or something longer-term, our partners at CNN Underscored, a product review and recommendations guide owned by CNN, have this roundup of the best kids’ luggage sets and bags. Starry, starry nights For close to 100 years, Michelin stars have been a sign of culinary excellence, awarded only to the great and good. Georges Blanc, the world’s longest-standing Michelin-starred restaurant, has boasted a three-star rating since 1981, but this month the Michelin guide announced that the restaurant in eastern France was losing a star. More culinary reputations were enhanced this week, when Asia’s 50 best restaurants for 2025 were revealed. The winner was a Bangkok restaurant which is no stranger to garlands, while second and third place went to two Hong Kong eateries. You don’t need to go to a heaving metropolis for excellent food, however. A 200-year-old cottage on a remote stretch of Ireland’s Atlantic coast has been given a Michelin star. At the time of awarding, Michelin called it “surely the most rural” of its newest winners.
