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.

Ukrainian Presidential Office: Russia's attacks on multiple locations in Ukraine have killed 36 people
The Ukrainian presidential office said on July 8 local time that Russia's large-scale attacks on many parts of Ukraine have killed 36 people and injured 140 others. According to the Ukrainian State Emergency Service, a total of 619 rescue workers and 132 equipment participated in the rescue work across Ukraine that day. Ukrainian President Zelensky said on social media on the 8th that Russia launched more than 40 missiles of various types at Ukraine that day. Residential buildings and infrastructure in many cities in Ukraine were damaged in varying degrees of attacks, and a children's hospital was destroyed. Rescue departments are currently conducting emergency rescue on the scene. The Russian Ministry of Defense issued a statement on the 8th local time saying that Ukrainian officials' claim that Russia used missiles to attack Ukrainian civilian facilities was untrue. The damage suffered by Kiev was caused by the fall of missiles launched by the city's air defense system.
Russian military launches massive missile attack, Kiev children's hospital hit; President Biden issues statement condemning Russia's "brutalism"
A children's hospital in the Ukrainian capital was hit by a Russian missile on Monday as part of a wave of airstrikes across Ukraine that has killed at least 31 people and injured 154 others. "Russian terrorists have once again launched a massive missile attack on Ukrainian cities - Kiev, Dnipro, Kryvyi Rih, Slaviansk, Kramatorsk," said Ukrainian President Volodymyr Zelenskyy. Zelensky said Russia fired more than 40 missiles of different types at the five cities in daytime attacks, hitting residential buildings and public infrastructure. The Ukrainian air force said it intercepted 30 missiles. Authorities said the attack on Kiev killed seven people, while the attack on Kryvyi Rih, Zelensky's birthplace in central Ukraine, killed 10 and injured 47. United Nations Secretary-General António Guterres condemned the attacks, calling the assault on the Kiev hospital and another medical facility in the capital's Dniprovsky district "particularly egregious," said his spokesman, Stephane Dujarric. "Direct attacks on civilians and civilian objects are prohibited under international humanitarian law. Any such attacks are unacceptable and must cease immediately," Dujarric said. The U.N. Security Council will meet Tuesday to discuss the Russian strikes, diplomats said. The Russian Defense Ministry said the strikes targeted Ukrainian defense factories and a military aviation base and were successful. It denied striking any civilian facilities and claimed, without evidence, that photos from Kiev showed the damage was caused by a Ukrainian anti-aircraft missile. Ukrainian Air Force Colonel Yurii Ignat said Russia has been improving the effectiveness of its air strikes by equipping its missiles with enhanced features, including so-called heat decoys that can throw air defense systems off target. In comments sent to The Associated Press, he said the cruise missiles flew low in Monday's attack -- just 50 meters off the ground -- making them harder to hit. Western countries, led by the United States, have provided Ukraine with billions of dollars in arms support. They will hold a three-day NATO summit in Washington starting Tuesday to work out how to reassure Kiev of NATO's strong support and give Ukrainians hope that their country can survive the largest conflict in Europe since World War II. "Today's Russian missile strike that killed dozens of Ukrainian civilians and caused damage and loss of life to Kyiv's largest children's hospital is a horrifying reminder of Russia's brutality," U.S. President Joe Biden said in a statement Monday. "It is critical that the world continues to stand with Ukraine at this important moment and that we do not ignore Russian aggression." Biden said in the statement that he will meet with President Zelensky during the NATO summit in Washington this week "to make clear our unwavering support for Ukraine." Biden continued: "We will join our allies in announcing new measures to strengthen Ukraine's air defenses and help protect their cities and civilians from Russian attacks. The United States stands with the Ukrainian people." Czech President Petr Pavel said the hospital attack was "inexcusable" and he hoped the NATO summit would reach a consensus that Russia is "the greatest threat and we must be fully prepared to deal with it." Zelensky said during a visit to Poland that he hoped the NATO summit would provide Ukraine with more air defense systems. The Ukrainian leader said rescuers were digging through the rubble of the Ohmatdit Children's Hospital in Kyiv and that the number of casualties was not yet known. Kyiv Mayor Vitali Klitschko said at least 16 people were injured, including seven children, and the attack caused a two-story wing of the hospital to partially collapse. Doors and windows were blown off the hospital's 10-story main building, and the walls were charred. The floor of one room was splattered with blood. Hospital officials said the intensive care unit, operating room and oncology department were damaged.
Australia pledges to provide more funds to Pacific island banks to counter China's influence
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.
US' ban on high-tech investment cannot stifle China's high-tech development
US President Joe Biden signed an executive order on Wednesday restricting investments in China, intended to further stymie China's advances in three cutting-edge technology areas: semiconductors and microelectronics, quantum information technologies and certain artificial intelligence systems. The "decoupling" of high tech from China began under Donald Trump, and the Biden administration has continued that ambition. However, the new order doesn't target US investments already invested in China, but the new ones. The Biden administration has repeatedly claimed that the US restrictions will be narrowly targeted and will not "have a fundamental impact on affecting the investment climate for China." Biden's new executive order is still subject to consultation with the US business community and the public and is not expected to take effect until next year. The order has been brewed for a long time and has generated a lot of publicity. But almost no one believes that this executive order will deal a new practical blow to Chinese high technology, because almost everyone knows that China needs American technology more than American money. The order has gained much attention because it is seen as part of a broader trend of the US drifting away from China. The promulgation and brewing process of the executive order reflects the strong desire of American political elites to suppress China's high-tech development, as well as a fierce game between those supporting the executive order and the concerns of the technology and economic sectors about a potential backfire on the US. It is a kind of compromise. Washington obviously hopes that major allies will follow Biden's executive order. The UK's Sunak government has made cautious statements, stating that it is consulting business and the financial sector before deciding whether to follow suit. In fact, China also has the ability to influence the extent to which Biden's executive order is implemented, as well as the extent to which the US will go in terms of "decoupling" from China. We are definitely not just passive recipients of US policies. American political elites are eager to "decouple" from China as quickly and deeply as possible, but they fear two things: First, this will immediately damage the performance of relevant high-tech companies in the US, undermine their influence and further innovation. The current Biden administration, in particular, does not want to incur strong resentment from Silicon Valley and Wall Street toward the escalating "decoupling," which will ultimately lead to the loss of support for the Democratic Party. Second, they are afraid of pushing China toward more resolute independent innovation to achieve breakthroughs in key technologies such as chips. If the US "decoupling" policy gives birth to major technological achievements in China, it means that Washington will completely lose the gamble: They originally wants to stifle China's high-tech development, but ends up strangling their own companies. What China needs to do next is to fully unleash our innovation vitality, continuously reduce our dependence on high-tech products from the US, and prove that as long as we are determined to achieve independent innovation, we have the ability to accomplish things. We need to prove that being pressured by the US will only make us stronger. As long as there are several solid proofs of this trend, the US policy community will fall into unprecedented chaos, and their panic will be much more severe than when they saw the rapid expansion of the Chinese economy before Trump started the trade war. Regardless of the future of China-US relations, the current battle will be the key battle that determines the future competition between China and the US. China can only win and cannot afford to lose. High-tech products such as chips are not isolated. The innovation power of China's entire manufacturing industry and the creative vitality of the whole society are the foundation for shaping these key achievements. When pressured by the US, our society needs to generate confidence and resilience from all directions, and we need to accelerate and seize every opportunity, rather than shrink and simply defend. Otherwise, the US will gain the upper hand in momentum, and we will truly be in a passive and defensive position. We must see that the US is on the offensive, but its offensive is becoming weaker and weaker, and it is always hesitant with each step. What is presented to China are difficulties and risks, but also the dawn of victory.
Stanford AI project team apologizes for plagiarizing Chinese model
An artificial intelligence (AI) team at Stanford University apologized for plagiarizing a large language model (LLM) from a Chinese AI company, which became a trending topic on the Chinese social media platforms, where it sparked concern among netizens on Tuesday. We apologize to the authors of MiniCPM [the AI model developed by a Chinese company] for any inconvenience that we caused for not doing the full diligence to verify and peer review the novelty of this work, the multimodal AI model Llama3-V's developers wrote in a post on social platform X. The apology came after the team from Stanford University announced Llama3-V on May 29, claiming it had comparable performance to GPT4-V and other models with the capability to train for less than $500. According to media reports, the announcement published by one of the team members quickly received more than 300,000 views. However, some netizens from X found and listed evidence of how the Llama3-V project code was reformatted and similar to MiniCPM-Llama3-V 2.5, an LLM developed by a Chinese technology company, ModelBest, and Tsinghua University. Two team members, Aksh Garg and Siddharth Sharma, reposted a netizen's query and apologized on Monday, while claiming that their role was to promote the model on Medium and X (formerly Twitter), and that they had been unable to contact the member who wrote the code for the project. They looked at recent papers to validate the novelty of the work but had not been informed of or were aware of any of the work by Open Lab for Big Model Base, which was founded by the Natural Language Processing Lab at Tsinghua University and ModelBest, according to their responses. They noted that they have taken all references to Llama3-V down in respect to the original work. In response, Liu Zhiyuan, chief scientist at ModelBest, spoke out on the Chinese social media platform Zhihu, saying that the Llama3-V team failed to comply with open-source protocols for respecting and honoring the achievements of previous researchers, thus seriously undermining the cornerstone of open-source sharing. According to a screenshot leaked online, Li Dahai, CEO of ModelBest, also made a post on his WeChat moment, saying that the two models were verified to have highly similarity in terms of providing answers and even the same errors, and that some relevant data had not yet been released to the public. He said the team hopes that their work will receive more attention and recognition, but not in this way. He also called for an open, cooperative and trusting community environment. Director of the Stanford Artificial Intelligence Laboratory Christopher Manning also responded to Garg's explanation on Sunday, commenting "How not to own your mistakes!" on X. As the incident became a trending topic on Sina Weibo, Chinese netizens commented that academic research should be factual, but the incident also proves that the technology development in China is progressing.
