WASHINGTON, July 8 (Reuters) - The planet known as HD 189733b, discovered in 2005, already had a reputation as a rather extreme place, a scorching hot gas giant a bit larger than Jupiter that is a striking cobalt blue color and has molten glass rain that blows sideways in its fierce atmospheric winds. So how can you top that? Add hydrogen sulfide, the chemical compound behind the stench of rotten eggs. Researchers said on Monday new data from the James Webb Space Telescope is giving a fuller picture of HD 189733b, already among the most thoroughly studied exoplanets, as planets beyond our solar system are called. A trace amount of hydrogen sulfide was detected in its atmosphere, a first for any exoplanet. "Yes, the stinky smell would certainly add to its already infamous reputation. This is not a planet we humans want to visit, but a valuable target for furthering our understanding of planetary science," said astrophysicist Guangwei Fu of Johns Hopkins University in Baltimore, lead author of the study published in the journal Nature, opens new tab. It is a type called a "hot Jupiter" - gas giants similar to the largest planet in our solar system, only much hotter owing to their close proximity to their host stars. This planet orbits 170 times closer to its host star than Jupiter does to the sun. It completes one orbit every two days as opposed to the 12 years Jupiter takes for one orbit of the sun. In fact, its orbit is 13 times nearer to its host star than our innermost planet Mercury is to the sun, leaving the temperature on the side of the planet facing the star at about 1,700 degrees Fahrenheit (930 degrees Celsius). "They are quite rare," Fu said of hot Jupiters. "About less than one in 100 star systems have them." This planet is located 64 light-years from Earth, considered in our neighborhood within the Milky Way galaxy, in the constellation Vulpecula. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). "The close distance makes it bright and easy for detailed studies. For example, the hydrogen sulfide detection reported here would be much more challenging to make on other faraway planets," Fu said. The star it orbits is smaller and cooler than the sun, and only about a third as luminous. That star is part of a binary system, meaning it is gravitationally bound to another star. Webb, which became operational in 2022, observes a wider wavelength range than earlier space telescopes, allowing for more thorough examinations of exoplanet atmospheres.

In a groundbreaking discovery, researchers from the Xinjiang Institute of Ecology and Geography of the Chinese Academy of Sciences have found a desert moss species, known as Syntrichia caninervis, that has the potential to survive in the extreme conditions on Mars. The Global Times learned from the institute that during the third Xinjiang scientific expedition, the research team focused on studying the desert moss and found that it not only challenges people's understanding of the tolerance of organisms in extreme environments, but also demonstrates the ability to survive and regenerate under simulated Martian conditions. Supported by the Xinjiang scientific expedition project, researchers Li Xiaoshuang, Zhang Daoyuan and Zhang Yuanming from the Xinjiang Institute of Ecology and Geography and Kuang Tingyun, an academician from the Chinese Academy of Sciences, concentrated on studying the "pioneer species" Syntrichia caninervis in an extreme desert environment, according to the institute in an article it sent to the Global Times on Sunday. Through scientific experiments, the researchers systematically proved that the moss can tolerate over 98 percent cell dehydration, survive at temperatures as low as -196 C without dying, withstand over 5000Gy of gamma radiation without perishing, and quickly recover, turn green, and resume growth, showcasing extraordinary resilience. These findings push the boundaries of human knowledge on the tolerance of organisms in extreme environments. Furthermore, the research revealed that under simulated Martian conditions with multiple adversities, Syntrichia caninervis can still survive and regenerate when returned to suitable conditions. This marks the first report of higher plants surviving under simulated Martian conditions. The research team also identified unique characteristics of Syntrichia caninervis. Its overlapping leaves reduce water evaporation, while the white tips of the leaves reflect intense sunlight. Additionally, the innovative "top-down" water absorption mode of the white tips efficiently collects and transports water from the atmosphere. Moreover, the moss can enter a selective metabolic dormancy state in adverse environments and rapidly provide the energy needed for recovery when its surrounding environment improves. Based on the extreme environmental tolerance of Syntrichia caninervis, the research team plans to conduct experiments on spacecraft to monitor the survival response and adaptation capabilities of the species under microgravity and various ionizing radiation adversities. They aim to unravel the physiological and molecular basis of the moss and explore the key life tolerance regulatory mechanisms, laying the foundation for future applications of Syntrichia caninervis in outer space colonization.

Australia pledged on Tuesday to increase investment in Pacific island nations, offering A$6.3 million ($4.3 million) to support their financial systems. Some Western banks are cutting ties with the region because of risk factors, while China is trying to increase its influence there. Some Western bankers have terminated long-standing banking relationships with small Pacific nations, while others are considering closing operations and restricting access to dollar-denominated bank accounts in those countries. "We know that the Pacific is the fastest-moving region in the world for correspondent banking services," Australian Treasurer Jim Chalmers said in a speech at the Pacific Banking Forum in Brisbane. "What's at stake here is the Pacific's ability to engage with the world," he said, with much of the region at risk of being cut off from the global financial system. Chalmers said Australia would provide A$6.3 million ($4.3 million) to the Pacific to develop secure digital identity infrastructure and strengthen compliance with anti-money laundering and counter-terrorist financing requirements. Experts say Western banks are de-risking to meet financial regulations, making it harder for them to do business in Pacific island nations, where compliance standards sometimes lag, undermining their financial resilience. Australia's ANZ Bank is in talks with governments about how to make its Pacific island businesses more profitable amid concerns about rising Chinese influence as financial services leave the West, Chief Executive Shayne Elliott said Tuesday. ANZ is the largest bank in the Pacific region, with operations in nine countries, though some of those businesses are not financially sustainable, Elliott said in an interview on the sidelines of the forum. "If we were there purely for commercial purposes, we would have closed it a long time ago," he said. Western countries, which have traditionally dominated the Pacific, are increasingly concerned about China's plans to expand its influence in the region after it signed several major defense, trade and financial agreements with the region. Bank of China signed an agreement with Nauru this year to explore opportunities in the country, following Australia's Bendigo Bank saying it would withdraw from the country. Mr. Chalmers said Australia was working with Nauru to ensure that banking services in the country could continue. ANZ Bank exited its retail business in Papua New Guinea in recent years, while Westpac considered selling its operations in Fiji and Papua New Guinea but decided to keep them. The Pacific lost about 80% of its correspondent banking relationships for dollar-denominated services between 2011 and 2022, Australian Assistant Treasurer Stephen Jones told the forum, which was co-hosted by Australia and the United States. “We would be very concerned if there were countries acting in the region whose primary objective was to advance their own national interests rather than the interests of Pacific island countries,” Mr. Jones said on the first day of the forum in Brisbane. He made the comment when asked about Chinese banks filling a vacuum in the Pacific. Meanwhile, Washington is stepping up efforts to support Pacific island countries in limiting Chinese influence. "We recognize the economic and strategic importance of the Pacific region, and we are committed to deepening engagement and cooperation with our allies and partners to enhance financial connectivity, investment and integration," said Brian Nelson, U.S. Treasury Undersecretary for Counterterrorism and Financial Intelligence. The United States is aware of the problem of Western banks de-risking in the Pacific region and is committed to addressing it, Nelson told the forum's participants. He said data showed that the number of correspondent banking relationships in the Pacific region has declined at twice the global average rate over the past decade, and the World Bank and the Asian Development Bank are developing plans to improve correspondent banking relationships. U.S. Treasury Secretary Janet Yellen said in a video address to the forum on Monday (July 8) that the United States is focused on supporting economic resilience in the Pacific region, including by strengthening access to correspondent banks. She said that when President Biden and Australian Prime Minister Anthony Albanese met at the White House last year, they particularly emphasized the importance of increasing economic connectivity, development and opportunities in the Pacific region, and a key to achieving that goal is to ensure that people and businesses in the region have access to the global financial system.

July 9 (Reuters) - The National Highway Traffic Safety Administration (NHTSA) has opened a recall query into 94,275 Stellantis-owned (STLAM.MI), opens new tab Jeep SUVs over a loss of motive power, the U.S. auto safety regulator said on Tuesday. The investigation targets Jeep's Wrangler 4xe hybrid SUVs manufactured between 2021 through 2024. Chrysler had previously recalled, opens new tab the same model in 2022 to address concerns related to an engine shutdown. A recall query is an investigation opened by safety regulators when a remedy to solve an issue appears inadequate. The complaints noted in the new report include both failures in vehicles that received the recall remedy and those not covered by the prior recall, the NHTSA said.

The world's deepest diving pool, Deepspot, opened this weekend near the Polish capital Warsaw. The 45.5-meter pool contains artificial underwater caves, Mayan ruins and a small shipwreck for scuba divers and free divers to explore. Deepspot can hold 8,000 cubic meters of water, more than 20 times the capacity of a normal 25-meter swimming pool. Unlike ordinary swimming pools, Deepspot can still open despite Poland's COVID-19 epidemic prevention restrictions because it is a training center that provides courses. The operator also plans to open a hotel where guests can observe divers at a depth of 5 meters from their rooms. "This is the deepest diving pool in the world," Michael Braszczynski, 47, Deepspot's director and a diving enthusiast, told AFP at the opening yesterday. The current Guinness World Record holder is a 42-meter-deep pool in Montegrotto Terme, Italy. The 50-meter-deep Blue Abyss pool in the UK is scheduled to open in 2021. On the first day of Deepspot's opening, about a dozen people visited, including eight experienced divers who wanted to pass the instructor exam. "There are no spectacular fish or coral reefs here, so it can't replace the ocean, but it is certainly a good place to learn and train safe open water diving," said 39-year-old diving instructor Przemyslaw Kacprzak. "And it's fun! It's like a kindergarten for divers."
