n a recent interview with ABC, US President Joe Biden said he had no intention of dropping out of the race, blaming his poor debate performance on a cold. He also insisted he was "still in good shape" and would remain in the race, saying only "Almighty God" could pull him out. An insider who has worked with Mr. Biden for a long time said that signs of aging had become apparent over the past year, but that Mr. Biden's team had failed to address it. Biden's televised debate performance heightened concerns about an already slow-moving issue. Mr. Biden's advisers have long dodged questions about his age. But now they acknowledge that Biden's aging is an undeniable fact. The debate forced the president to more openly acknowledge the limitations of his age, which he had previously largely dismissed. But they have only taken superficial measures and have not fundamentally solved the problem. They replaced the long staircase that Mr. Biden used to board Air Force One with a shorter one; Assistants often accompanied him in public to make his stiff gait less noticeable; While he has a busy schedule, aides have arranged for buffer time, such as long weekends at his homes in Wilmington and Rehoboth Beach, Delaware, or extended stays at Camp David, a Maryland resort, to rest after a "grueling" stretch of travel. Under the authority of one of his top advisers, Anita Dunn, Mr. Biden's public interactions -- especially with reporters -- were severely limited. Even at major events with Democrats or other supporters, the White House sometimes limits the amount of time Biden can spend with the audience, two people familiar with the matter said. As a protective response, designed to protect their longtime boss.

At the beginning of this year, Elon Musk had a fortune of $251 billion and could almost single-handedly solve world hunger. However, Tesla's stagnant sales, the endless struggle to buy Twitter, and the volatility of Tesla's stock price meant he lost a lot of money this year. According to Forbes, Musk is the billionaire with the most losses so far this year, with his wealth shrinking at a rate of about $5 billion a month. According to the website, his wealth shrank by more than 10% from the end of 2023 to June 28, 2024. As the website explains: Between December 31, 2023, and June 28, the last day of regular stock market trading for the first half of the year, Musk's net worth fell from $251.3 billion to $221.4 billion, a bigger drop than any other billionaire tracked by Forbes, but Musk remains the richest person on the planet. The main reason for the dip in Musk's pocketbook is that a Delaware judge in January canceled Musk's then-record Tesla compensation package worth $51 billion, which led Forbes to cut the value of the equity award by 50 percent because of uncertainty about whether Musk would receive those stock options. Excluding that bonus, Musk's wealth has remained volatile over the past six months, with the value of his 13 percent stake in Tesla shrinking by about $20 billion as falling profits and car deliveries sent the stock down 20 percent. But that was partly offset by the growth of Musk's stake in his generative artificial intelligence startup xAI to $14.4 billion (Musk also has a roughly $75 billion stake in private aerospace company SpaceX, a $7 billion stake in social media company X, And smaller stakes in other companies, such as brain experimentation startup Neuralink).

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.

On June 27, the U.S. Space Command announced that a retired Russian satellite disintegrated in low Earth orbit on June 26, generating more than 100 pieces of debris, forcing astronauts on the International Space Station to hide for about an hour. The X-platform account of the International Space Station showed that shortly after 9 p.m. Eastern Time on June 26, NASA instructed the crew on the space station to hide in their respective spacecraft for safety because NASA learned in the morning of the 26th that a satellite disintegrated near the space station. About an hour later, the crew was allowed to leave the spacecraft and the space station resumed normal operation. There are rumors on social platforms that the satellite hit six U.S. GPS satellites after the disintegration and damaged 20 Starlink satellites developed by Space Exploration Technologies Corporation (SpaceX) led by Musk, triggering speculation that the relevant satellites were deliberately disintegrated.

Byd has grown rapidly in China over the past few years, becoming the country's best-selling car brand and the world's biggest selling electric car brand. Byd opened its first electric car factory in Southeast Asia on Thursday in Thailand. Byd also took over a former Ford Motor Co. plant in Brazil and has been looking for a site for a Mexican plant. Europe's first automotive plant is under construction in Hungary. Byd's second-quarter sales jumped to a record 982,747 vehicles, up more than 40 per cent from a year earlier. Although the company's sales in Europe have been sluggish so far, it is making a big marketing push in the region to replace Volkswagen as the main automotive sponsor of the European Championship. According to a recent Fortune report, officials said that Turkish President Recep Tayyip Erdogan is expected to announce the agreement for BYD to build the plant at a signing ceremony on Monday in Manisa province, where the plant will be built. The officials spoke on condition of anonymity because they were not authorized to speak publicly. Byd representatives declined to comment. Turkish Industry and Technology Minister Mohamed Fatih Kassir said in May that he was in advanced discussions with BYD and Chery on investment in Turkey. The new plant will improve BYD's access to the European Union, as Turkey has a customs union agreement with the EU. The European Union this week announced temporary punitive tariffs on electric vehicles imported from China, with BYD imposing an additional 17.4 percent tariff on top of the existing 10 percent tariff. Other Chinese carmakers have been hit with higher tariffs. Investing in Turkey would strengthen the presence of Chinese carmakers in Europe at a time of escalating trade tensions.
