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.

How China can transform from passive to active amid US chip curbs
On Monday, executives from the three major chip giants in the US - Intel, Qualcomm, and Nvidia - met with US officials, including Antony Blinken, to voice their opposition to the Biden administration's plan of imposing further restrictions on chip sales to Chinese companies and investments in China. The Semiconductor Industry Association also released a similar statement, opposing the exclusion of US semiconductor companies from the Chinese market. First of all, we mustn't believe that the appeals of these companies and industry associations will collectively change the determination of US political elites to stifle China's progress. These US elites are very fearful of China's rapid development, and they see "chip chokehold" as a new discovery and a successful tactic formed under US leadership and with the cooperation of allies. Currently, the chip industry is the most complex technology in human history, with only a few companies being at the forefront. They are mainly from the Netherlands, Taiwan island, South Korea, and Japan, most of which are in the Western Pacific. These countries and regions are heavily influenced by the US. Although these companies have their own expertise, they still use some American technologies in their products. Therefore, Washington quickly persuaded them to form an alliance to collectively prevent the Chinese mainland from obtaining chips and manufacturing technology. Washington is proud of this and wants to continuously tighten the noose on China. The New York Times directly titled an article "'An Act of War': Inside America's Silicon Blockade Against China, " in which an American AI expert, Gregory Allen, publicly claimed that this is an act of war against China. He further stated that there are two dates that will echo in history from 2022: The first is February 24, when the Russia-Ukraine conflict broke out, and the second is October 7, when the US imposed a sweeping set of export controls on selling microchips to China. China must abandon its illusions and launch a challenging and effective counterattack. We already have the capability to produce 28nm chips, and we can use "small chip" technology to assemble small semiconductors into a more powerful "brain," exploring 14nm or even 7nm. Additionally, China is the world's largest commercial market for commodity semiconductors. Last year, semiconductor procurement in China amounted to $180 billion, surpassing one-third of the global total. In the past, China had been faced with the choice between independent innovation and external purchases. Due to the high returns from external purchases, it is easy for it to become the overwhelming choice over independent research and development. However, now the US is gradually blocking the option of external purchases, and China has no strategic choice but to independently innovate, which in turn puts tremendous pressure on American companies. Scientists generally expect that, although China may take some detours, such as recently apprehending several company leaders who fraudulently obtained subsidies from national semiconductor policies, China has the ability to gradually overcome the chip difficulties. And we will form our own breakthroughs and industrial chain, which is expected to put quite a lot of pressure on US companies. If domestic firms acquire half of China's $180 billion per year in chip acquisitions, this would provide a significant boost for the industry as a whole and help it advance steadily. The New York Times refers to the battle on chips as a bet by Washington. "If the controls are successful, they could handicap China for a generation; if they fail, they may backfire spectacularly, hastening the very future the United States is trying desperately to avoid," it argued. Whether it is a war or a game, when the future is uncertain, what US companies hope for most of all is that they can sell simplified versions of high-end chips to China, so that the option of external purchases by China continues to exist and remains attractive. This can not only maintain the interests of the US companies, enabling them to obtain sufficient funds to develop more advanced technologies, but also disrupt China's plans for independent innovation. This idea is entirely based on their own commercial interests and also has a certain political and national strategic appeal. Hence, there is no shortage of supporters within the US government. US Secretary of the Treasury Janet Yellen seems to be one of them, as she has repeatedly stated that the US' restrictions on China will not "fundamentally" hurt China, but will only be "narrowly targeted." The US will balance its strict suppression on China from the perspective of maintaining its technological hegemony, while also leaving some room for China, in order to undermine China's determination to counterattack in terms of independent innovation. China needs to use this mentality of the US to its advantage. On the one hand, China should continue to purchase US chips to maintain its economic fundamentals, and on the other hand, it should firmly support the development of domestic semiconductor companies from both financial and market perspectives. If China were to continue relying on exploiting the gaps in US chip policies in the long term, akin to a dependency on opium, it would only serve to weaken China further as it becomes increasingly addicted. China's market is extremely vast, and its innovation capabilities are generally improving and expanding. Although the chip industry is highly advanced, if there is one country that can win this counterattack, it is China. As long as we resolutely continue on the path of independent innovation, this road will definitely become wider. Various breakthroughs and turning points that are unimaginable today may soon occur.
Japan and the Philippines signed the "Reciprocal Access Agreement". Experts: Japan wants to use the Philippines to strategically contain China
Japan and the Philippines signed an important defense agreement, and the two sides became "quasi-allies". On July 8, local time, Japan and the Philippines signed the "Reciprocal Access Agreement" in Manila. The agreement will relax restrictions on the movement of personnel between the Japanese Self-Defense Forces and the Philippine military during joint exercises, mutual visits and other operations in each other's countries. In response, Chinese Foreign Ministry spokesman Lin Jian responded at a regular press conference on the 8th that exchanges and cooperation between countries should not undermine mutual understanding and trust between regional countries, should not undermine regional peace and stability, and should not target third parties or undermine the interests of third parties. The Asia-Pacific region does not need military groups, let alone "small circles" that provoke camp confrontation and instigate a "new Cold War". Any actions that undermine peace and stability in the region and undermine unity and cooperation in the region will arouse the vigilance and common opposition of the people in the region. Japan and the Philippines upgraded to a "quasi-alliance" relationship On the same day, a "2+2" meeting attended by the foreign ministers and defense ministers of Japan and the Philippines was held in Manila. Japanese Defense Minister Minoru Kihara and Foreign Minister Yoko Kamikawa attended the talks with Philippine Defense Minister Gilbert Teodoro and Foreign Minister Enrique Manalo. This is the second Japan-Philippines "2+2" meeting. The last one was held in Tokyo in April 2022. Witnessed by Philippine President Marcos, the two sides signed the "Reciprocal Access Agreement". Marcos expressed the hope that the bilateral relations between the Philippines and Japan and the trilateral cooperation between the Philippines, Japan and the United States will be further deepened. The "Reciprocal Access Agreement" is also known as the "Military Visits Agreement". Military and defense cooperation between sovereign states, especially sending troops into each other's territory, usually faces complicated procedures and other problems. In order to simplify the procedures, the two countries will reach relevant agreements to simplify the approval procedures for the entry of troops from both sides into each other's countries, and facilitate mutual visits and joint military activities between the two countries' troops. The "Reciprocal Access Agreement" was born. Take the "Reciprocal Access Agreement" signed by Japan and Australia (full name "Agreement between Japan and Australia on Promoting Mutual Access and Cooperation Facilitation between the Japanese Self-Defense Forces and the Australian Defense Force") as an example. The agreement has 29 articles, covering many areas such as entry and exit procedures for troops, jurisdiction, taxation, cost burden and compensation. The key is to simplify the entry and exit procedures for visiting troops and their members, ships, aircraft, etc., relax restrictions on the transportation of weapons, ammunition and materials carried by visiting troops, and provide a legal basis for the two countries' troops and weapons and equipment to enter each other's territory. Japan and the Philippines signed the "Reciprocal Access Agreement", making the Philippines the third country to conclude this agreement with Japan after Australia and the United Kingdom. Cai Liang, Secretary-General and Researcher of the China-Japan Relations Research Center of the Shanghai Institute for International Studies, analyzed to The Paper (www.thepaper.cn) that Japan and the Philippines have their own strategic considerations for signing the "Reciprocal Access Agreement". As for the Philippines, due to its limited strength, it does not exclude any foreign power willing to strengthen military cooperation with the Philippines from intervening in the South China Sea situation. Therefore, it can be seen that in the past two years, the Philippines has actively promoted Australia, France, India and other countries to intervene in the South China Sea and strengthen military cooperation with them, involving intelligence, weapons and equipment, and training and exercises. "Japan's purpose is very simple. Strengthening military cooperation with the Philippines is to strategically balance China. The United States and the Philippines are allies, and the US-Japan alliance has been upgraded to a 'quasi-alliance'. The military cooperation between the United States, Japan and the Philippines has been upgraded to a new level." Cai Liang said, "The signing of an important defense agreement between Japan and the Philippines will make it easier for Japan to intervene in the South China Sea situation and seek the 'three seas linkage' of the East China Sea, the South China Sea, and the Taiwan Strait, in order to better respond to China's strategy and enhance its international influence." As for whether the signing of the "Reciprocal Access Agreement" means that Japan will deploy the Self-Defense Forces in the Philippines, Cai Liang pointed out that this agreement only simplifies the procedures for the troops of both sides to enter each other's territory, and is more suitable for short-term training, military exercises, etc., and is not a long-term deployment of the Self-Defense Forces in the Philippines. The two countries deepen military cooperation The Philippine presidential office also said in a statement that Japan is one of the four major strategic partners of the Philippines, and the two countries have established a strategic partnership for more than ten years. It seems no coincidence that Japan and the Philippines signed the "Reciprocal Access Agreement" at this time. Recently, China-Philippines relations have become tense around the situation in the South China Sea. The Global Times quoted Japan's Kyodo News Agency as saying that the two sides are seeking to strengthen cooperation against China. Minoru Kihara said last week: "The Philippines is located in a strategically important region, occupies a key position on Japan's sea lanes, and is also an ally of the United States. Joint training and strengthening cooperation with the Philippines are of great significance to the realization of a 'free and open Indo-Pacific region'." Cai Liang said that Japan's intervention in the South China Sea situation is mainly to reduce strategic pressure in the East China Sea and southwest of Japan, but it is not conducive to peace and stability in the South China Sea. It is reported that Japan and the Philippines began negotiations on the agreement in November last year. The signing of the "Reciprocal Access Agreement" by the two sides lays the foundation for the two countries to strengthen bilateral and even multilateral military cooperation in the future. The Japanese government intends to allow the Self-Defense Forces to formally participate in the annual US-Philippines "Shoulder to Shoulder" joint exercises around the Philippines after the agreement comes into effect. The Self-Defense Forces previously participated in the "Shoulder to Shoulder" exercises as observers, and will be able to formally participate after signing the agreement. In April this year, the United States and the Philippines held the largest "Shoulder to Shoulder" exercise to date, involving 5,000 Philippine personnel and 11,000 US personnel. The military exercise also included about 150 Australian military personnel and 100 French naval personnel. According to the plan, 14 countries including Japan and India sent personnel as observers. The "Typhon" medium-range missile launch system deployed by the US military on Luzon Island in the Philippines for the first time participated in the exercise, which aroused great attention from all walks of life. In terms of weapons and equipment exports, Japan and the Philippines have gradually strengthened military cooperation in recent years. The Philippines recently agreed to purchase five Coast Guard patrol ships from Japan to enhance its patrol capabilities in the South China Sea. Defense News reported in November last year that the Philippines had received an early warning radar system from Japan in 2023, the first major equipment transfer since the Japanese government lifted the postwar defense export ban in 2014. The Japanese Ministry of Foreign Affairs stated that Kamikawa mentioned topics such as defense equipment transfer, "government security capability enhancement support" (OSA), and economic and trade cooperation. The OSA project was created by the Kishida government and plans to allocate billions of yen in budget to assist the military construction of the Philippines and other countries, including providing the Philippines with 5 sets of coastal surveillance radars. Regarding Japan's relaxation of restrictions on defense equipment exports, the Chinese Ministry of Defense previously responded that Japan has continuously broken through the constraints of the "peace constitution" and the principle of "exclusive defense", and has been making small moves in the field of military security, which has aroused high vigilance and strong concern from the international community. China requires Japan to deeply reflect on its history of aggression, attach importance to the security concerns of its Asian neighbors, adhere to the path of peaceful development, and win the trust of its Asian neighbors and the international community with practical actions.
The Apple Watch is reportedly getting a birthday makeover
Apple is planning to revamp its smartwatch as its 10th birthday nears. The improvements include larger displays and thinner builds, Bloomberg reported. The revamped watches may also get a new chip, which could enable some AI enhancements. The Apple Watch is about to turn 10, so Apple is planning a birthday revamp, including larger displays and thinner builds, Bloomberg reported. Both versions of the new Series 10 watches will have screens similar to the large displays found on the Apple Watch Ultra, the report said. The revamped watches are also expected to contain a new chip that may permit some AI enhancements later on. Last month, Apple pulled back the curtain on its generative-AI plans with Apple Intelligence. Advertisement It hopes the artificial-intelligence features will prove alluring enough to persuade consumers to buy new Apple products. The announcement has been generally well received by Wall Street. Dan Ives of Wedbush Securities wrote in a Monday note that the "iPhone 16 AI-driven upgrade could represent a golden upgrade cycle for Cupertino." "We believe AI technology being introduced into the Apple ecosystem will bring monetization opportunities on both the services as well as iPhone/hardware front and adds $30 to $40 per share," he added. Apple's stock closed on Friday at just over $226 a share, up 22% this year and valuing the company at $3.47 trillion. That puts it just behind Microsoft, which was worth $3.48 trillion at Friday's close. The tech giants have been vying for the title of the world's most valuable company in recent months — with the chipmaker Nvidia briefing claiming the crown last month. Apple also announced some software updates for the watch at its Worldwide Developers Conference last month. The latest version of the device's software, watchOS 11, emphasizes fitness and health, introducing tools that allow users to rate workouts and adjust effort ratings. WatchOS 11 will also use machine learning to curate the best photos for users' displays. Apple has previously used product birthdays to release new versions of devices. The iPhone X's release marked the 10th anniversary of the smartphone. However, it's not clear exactly when Apple plans to release the revamped watches, Bloomberg said. The company announced the Apple Watch in September 2014, with CEO Tim Cook calling it "the most personal product we've ever made." Apple did not immediately respond to a request for comment made outside normal working hours.
South Korean government decides not to punish interns who resign
South Korea's Minister of Health and Welfare Cho Kyu-hong said at a press conference on the 8th local time that after comprehensively considering the suggestions of frontline interns and the situation on the front line of medical care, the government decided that from that day on, all interns and residents who resigned would not be given administrative sanctions such as revoking their medical licenses. Cho Kyu-hong also said that for interns and residents who have returned to work and those who have resigned and are preparing to re-register for internship courses in September, the government will make special cases to try to minimize the internship gap and not affect the relevant doctors from obtaining specialist medical licenses. Cho Kyu-hong said that the government believes that in order to minimize the diagnosis and treatment gaps for critically ill and emergency patients and ensure the smooth training process of interns and residents, it is in the public interest, so it has made a decision not to punish interns and residents who resigned. It is hoped that major hospitals will complete the resignation processing of doctors who have not returned to work before July 15 and determine the scale of vacancies. Previously, large general hospitals in South Korea, such as Seoul National University Hospital, Yonsei University Severance Hospital, and Seoul Asan Medical Center, suspended or limited their medical services in an effort to cancel all penalties against interns and residents.
Hamas chief says latest Israeli attack on Gaza could jeopardise ceasefire talks
AIRO, July 8 (Reuters) - A new Israeli assault on Gaza on Monday threatened ceasefire talks at a crucial moment, the head of Hamas said, as Israeli tanks pressed into the heart of Gaza City and ordered residents out after a night of massive bombardment. Residents said the airstrikes and artillery barrages were among the heaviest in nine months of conflict between Israeli forces and Hamas militants in the enclave. Thousands fled. The assault unfolded as senior U.S. officials were in the region pushing for a ceasefire after Hamas made major concessions last week. The militant group said the new offensive appeared intended to derail the talks and called for mediators to rein in Israel's Prime Minister Benjamin Netanyahu. The assault "could bring the negotiation process back to square one. Netanyahu and his army will bear full responsibility for the collapse of this path," Hamas quoted leader Ismail Haniyeh as saying. Gaza City, in the north of the Palestinian enclave, was one of Israel's first targets at the start of the war in October. But clashes with militants there have persisted and civilians have sought shelter elsewhere, adding to waves of displacement. Much of the city lies in ruins. Residents said Gaza City neighbourhoods were bombed through the night into the early morning hours of Monday. Several multi-storey buildings were destroyed, they said. The Gaza Civil Emergency Service said it believed dozens of people were killed but emergency teams were unable to reach them because of ongoing offensives. Gaza residents said tanks advanced from at least three directions on Monday and reached the heart of Gaza City, backed by heavy Israeli fire from the air and ground. That forced thousands of people out of their homes to look for safer shelter, which for many was impossible to find, and some slept on the roadside.
