Rotten eggs chemical detected on Jupiter-like alien planet

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.

Xinjiang scientists discover plant with potential to survive on Mars
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.
Wto: Members have more trade promotion measures than restrictions
The latest trade monitor released recently by the World Trade Organization shows that between mid-October 2023 and mid-May 2024, WTO members continued to introduce more trade promotion measures than trade restrictive measures. The WTO said it was an important signal of members' commitment to keep trade flowing amid the current geopolitical uncertainty. According to WTO statistics, during the monitoring period, WTO members adopted 169 trade promotion measures on commodities, more than the 99 trade restrictive measures introduced. Most of the measures are aimed at imports. Commenting on the findings, WTO Director-General Ngozi Okonjo-Iweala said that despite the challenging geopolitical environment, this latest trade monitoring report highlights the resilience of world trade. Even against the backdrop of rising protectionist pressures and signs of economic fragmentation, governments around the world are taking meaningful steps to liberalize and boost trade. This demonstrates the benefits of trade on people's purchasing power, business competitiveness and price stability. The WTO monitoring also identified significant new developments in economic support measures. Subsidies as part of industrial policy are increasing rapidly, especially in areas related to climate change and national security.
Hollywood's strongest supporting actor has been launched, AI is not far from subverting "Dreamworks"?
As a major city in the United States and even the global film industry, Hollywood has gathered a large number of veteran film and television production companies, including Universal Pictures, Warner Bros., Paramount Pictures, Disney Pictures, MGM Pictures, etc. In addition, new streaming forces such as Netflix have also entered in recent years. When the new generation of technology represented by generative AI sweeps the world, the movie "dream factory" is also experiencing a transformative moment. In early May last year, the US film and television industry launched a series of strikes that lasted for five months. Two labor disputes, led by the Writers Guild and the Screen Actors Guild, have caused the worst industry disruption since the 2020 pandemic, forcing many film projects and TV shows to halt or delay production. The strike has been costly, with Kevin Klowden, chief global strategist at the Milken Institute think tank, estimating it has cost the U.S. economy more than $5 billion, affecting not only film and television production companies, but also surrounding service industries such as catering, trucking and dry cleaning. One of the main conflicts between labor and management is that many actors and screenwriters have expressed concerns about "unemployment" due to the "invasion" of artificial intelligence. Luo Chenya has been working in the film and television industry for more than 10 years, including scriptwriter, documentary photographer and assistant director. She told the first financial reporter that after ChatGPT became popular, she also tried to use chatbots to assist script creation. "I can talk to the AI about my ideas and ideas, and it will help analyze and refine my ideas, and even make some suggestions that I think are quite effective." But on the execution level, the idea of writing it down into a very specific scene, character action, it doesn't really help me." Luo Chenya said that AI still needs more training and evolution in script writing, but the ability to present images is amazing. "AI can directly generate images, which can indeed save labor to a great extent, and may even replace photographers in the future." In post-production, AI can beautify images and modify flaws." A place to be fought over Earlier this year, OpenAI released the Vincennes video model Sora on its website, which can create videos up to a minute long, generating complex scenes with multiple characters, specific types of movement, and precise theme and background details. In addition to being able to generate video from text, the model can also generate video from still images, precisely animating the image content. "Vincennes Video can quickly produce high-quality video content, greatly improving production efficiency, and generative AI helps to improve the analysis of user preferences and personalized recommendations, and enhance the attractiveness of content." These technologies will disrupt traditional video production and content distribution models, and media companies need to adapt and change their operating models." Wang Haoyu, CEO of Mairui Asset Management, said in an interview with the first financial reporter. For this reason, Hollywood giants have long made big bets and stepped up their layout.
Workers warn of additional walkouts unless demands are met
Members of the National Samsung Electronics Union stage a rally near the company's Hwaseong Campus in Gyeonggi Province, Monday, beginning a three-day strike. Korea Times photo by Shim Hyun-chul By Nam Hyun-woo The biggest labor union at Samsung Electronics initiated a three-day strike on Monday, threatening to disrupt the company's chip manufacturing lines unless management agrees to a wage hike and higher incentives. This marks the first strike by unionized workers in the tech giant's 55-year history. The National Samsung Electronics Union (NSEU) claimed that about 4,000 unionized workers from Samsung's plants nationwide participated in a rally at the company's Hwaseong Campus in Gyeonggi Province. Police estimated that approximately 3,000 union members were present at the rally. According to its own survey, the union reported that a total of 6,540 members expressed their intention to participate in the strike. They emphasized that disruptions in manufacturing are anticipated, with over 5,000 members from facility, manufacturing, and development divisions joining the strike. The comments seem to address market expectations that the walkout is unlikely to cause significant disruptions in the chipmaker's operations, largely because most manufacturing lines are automated. The union said that it may launch another strike for an undetermined period, unless management responds to the union’s demand. Since January, the union has been pressing management for a higher wage increase rate for all members, fulfillment of promises regarding paid leave, and improvements to incentive criteria. With negotiations at an impasse, the union announced on May 29 that it would launch a strike. The NSEU has some 30,000 members, accounting for 24 percent of all Samsung employees. Among the union members, about 80 percent work at the device solutions division, which manufactures semiconductors.
US foreign policy is advanced smartphone with weak battery
A couple of days ago, a Quad summit meeting in Sydney scheduled for May 24 was abruptly canceled. The US president had to pull out of his long-anticipated trip to Australia and Papua New Guinea. Instead, the heads of the four Quad member states got together on the margins of the G7 Summit in Hiroshima on May 20. The main reason for the change of plans was the continuous struggle between the White House and Republicans on the Hill over the national debt ceiling. If no compromise is reached, the US federal government might fail to meet its financial commitments already in June; such a technical default would have multiple negative repercussions for the US, as well as for the global economy and finance at large. Let us hope that a compromise between the two branches of US power will be found and that the ceiling of the national debt will be raised once again. However, this rather awkward last-minute cancellation of the Quad summit reflects a fundamental US problem - a growing imbalance between the US geopolitical ambitions and the fragility of the national financial foundation to serve these ambitions. The Biden administration appears to be fully committed to bringing humankind back to the unipolar world that existed right after the end of the Cold War some 30 years ago, but the White House no longer has enough resources at its disposal to sustain such an undertaking. As they say in America: You cannot not have champagne on a beer budget. The growing gap between the ends that the US seeks in international relations and the means that it has available is particularly striking in the case of the so-called dual containment policy that Washington now pursues toward Russia and China. Even half a century ago, when the US was much stronger in relative terms than it is today, the Nixon administration realized that containing both Moscow and Beijing simultaneously was not a good idea: "Dual containment" would imply prohibitively high economic costs for the US and would result in too many unpredictable political risks. The Nixon administration decided to focus on containing the Soviet Union as the most important US strategic adversary of the time. This is why Henry Kissinger flew to Beijing in July 1971 to arrange the first US-China summit in February 1972 leading to a subsequent rapid rapprochement between the two nations. In the early days of the Biden administration, it seemed that the White House was once again trying to avoid the unattractive "dual containment" option. The White House rushed to extend the New START in January 2021 and held an early US-Russia summit meeting five months later in Geneva. At that point many analysts predicted that Biden would play Henry Kissinger in reverse - that is he would try to peace with the relatively weaker opponent (Moscow) in order to focus on containing the stronger one (Beijing). However, after the beginning of the Russia-Ukraine conflict, it became clear that no accommodation with the Kremlin was on Biden's mind any longer. Still, having decided to take a hard-line stance toward Moscow and to lead a broad Western coalition in providing military and economic assistance to Kiev, Washington has not opted for a more accommodative or at least a more flexible policy toward Beijing. On the contrary, over last year one could observe a continuous hardening of the US' China policy - including granting more political and military support to the Taiwan island, encouraging US allies and partners in Asia to increase their defense spending, engaging in more navel activities in the Pacific and imposing more technology sanctions on China. In the meantime, economic and social problems within the US are mounting. The national debt ceiling is only the tip of an iceberg - the future of the American economy is now clouded by high US Federal Reserve interest rates that slow down growth, feed unemployment and might well lead to a recession. Moreover, the US society remains split along the same lines it was during the presidency of Donald Trump. The Biden administration has clearly failed to reunite America: Many of the social, political, regional, ethnic and even generational divisions have got only deeper since January 2021. It is hard to imagine how a nation divided so deeply and along so many lines could demonstrate continuity and strategic vision in its foreign policy, or to allocate financial resources needed to sustain a visionary and consistent global leadership. Of course, the "dual containment" policy is not the only illustration of the gap between the US ambitions and its resources. The same gap inevitably pops up at every major forum that the US conducts with select groups of countries from the Global South - Africa, Southeast Asia, Latin America or the Middle East. The Biden administration has no shortage of arguments warning these countries about potential perils of cooperating with Moscow or Beijing, but it does not offer too many plausible alternatives that would showcase the US generosity, its strategic vision, and its true commitment to the burning needs of the US interlocutors. To cut it short, Uncle Sam brings lots of sticks to such meetings, but not enough carrots to win the audience. In sum, US foreign policy under President Joe Biden reminds people of a very advanced and highly sophisticated smartphone that has a rather weak battery, which is not really energy efficient. The proud owner of the gadget has to look perennially for a power socket in order not to have the phone running out of power at any inappropriate moment. Maybe the time has come for the smartphone owner to look for another model that would have fewer fancy apps, but a stronger and a more efficient battery, which will make the appliance more convenient and reliable.
