United Airlines confirmed that a tire fell off a Boeing 757 passenger plane when it took off from Los Angeles International Airport in the early morning of July 8, local time. It is reported that there has been no report of any material damage or casualties in this accident. United Airlines said in a statement that the aircraft tire has been found and the investigation is ongoing. There were 174 passengers and 7 crew members on the flight involved. The flight left Los Angeles International Airport at around 7:15 on July 8 and flew to Denver. Unlike the aircraft tire falling incident on a United Airlines flight in March, the pilot of this flight continued the journey to Denver and landed smoothly there.

Samsung Electronics expects its profits for the three months to June 2024 to jump 15-fold compared to the same period last year. An artificial intelligence (AI) boom has lifted the prices of advanced chips, driving up the firm's forecast for the second quarter. The South Korean tech giant is the world's largest maker of memory chips, smartphones and televisions. The announcement pushed Samsung shares up more than 2% during early trading hours in Seoul. The firm also reported a more than 10-fold jump in its profits for the first three months of this year. In this quarter, it said it is expecting its profit to rise to 10.4tn won ($7.54bn; £5.9bn), from 670bn won last year. That surpasses analysts' forecasts of 8.8tn won, according to LSEG SmartEstimate. "Right now we are seeing skyrocketing demand for AI chips in data centers and smartphones," said Marc Einstein, chief analyst at Tokyo-based research and advisory firm ITR Corporation. Optimism about AI is one reason for the broader market rally over the last year, which pushed the S&P 500 and the Nasdaq in the United States to new records on Wednesday. The market value of chip-making giant Nvidia surged past $3tn last month, briefly holding the top spot as the world's most valuable company. "The AI boom which massively boosted Nvidia is also boosting Samsung's earnings and indeed those of the entire sector," Mr Einstein added. Samsung Electronics is the flagship unit of South Korean conglomerate Samsung Group. Next week, the tech company faces a possible three-day strike, which is expected to start on Monday. A union of workers is demanding a more transparent system for bonuses and time off.

More than 6,500 employees at South Korea's Samsung Electronics began a three-day mass strike on Monday (July 8), demanding an extra day of paid annual leave, higher pay raises and changes to the way performance bonuses are currently calculated. This is the largest organized strike in Samsung Electronics' more than half century of existence, and the union said that if this strike does not push employees' demands to be met, a new strike may be called. One of the core issues of the current dispute between the labor union and Samsung Electronics is raising wages and increasing the number of paid vacation days. The second demand is a pay rise. The union originally wanted a pay rise of more than 3% for its 855 employees, but last week they changed their demand to include all employees (rather than just 855). The third issue involves performance bonuses linked to Samsung's outsized profits - chip workers did not receive the bonuses last year when Samsung lost about Won15tn and, according to unions, fear they will still not get the money even if the company manages to turn around this year.

Taking the initiative to plead guilty to Boeing is not small, but it can avoid being exposed to more problems when it is publicly tried, which is a "minor penalty" for Boeing. So now the families of the crash victims are very opposed to the move, demanding that the trial continue to be open. But after all, Boeing is America's oldest industrial son, whether it is Trump or Biden, and finally have to gently put down, give a chance. The Justice Department had been seeking a guilty plea from Boeing as early as May, when it launched the investigation. After all, if you plead guilty, you only need to pay a fine, and if you really go to court, you don't know how many quality problems Boeing will be exposed by your witnesses. Boeing also knew it had too many flaws, and paying a $243.6 million fine and bringing in a third party to monitor its compliance for three years, totaling more than $400 million in additional expenses, is small change for Boeing. Given Boeing's style in the past few years, this fine may not even force Boeing to tighten production line management. Just this kind of "reconciliation" that completely excludes the victims of the crash can not get the families to agree. Paul Cassell, an attorney for the victims' families, said he plans to ask the federal judge overseeing the case to reject the agreement and "hold this case to an open trial so that all the facts of this case can be presented in a fair and public manner before a jury." The demand is reasonable, but the US judge will most likely side with Boeing.

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.
