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.

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.

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.

CAIRO/GAZA, July 6 (Reuters) - At least 16 people were killed in an Israeli strike on a school sheltering displaced Palestinian families in central Gaza on Saturday, the Palestinian health ministry said, in an attack Israel said had targeted militants. The health ministry said the attack on the school in Al-Nuseirat killed at least 16 people and wounded more than 50. The Israeli military said it took precautions to minimize risk to civilians before it targeted the gunmen who were using the area as a hideout to plan and carry out attacks against soldiers. Hamas denied its fighters were there. At the scene, Ayman al-Atouneh said he saw children among the dead. "We came here running to see the targeted area, we saw bodies of children, in pieces, this is a playground, there was a trampoline here, there were swing-sets, and vendors," he said. Mahmoud Basal, spokesman of the Gaza Civil Emergency Service, said in a statement that the number of dead could rise because many of the wounded were in critical condition. The attack meant no place in the enclave was safe for families who leave their houses to seek shelters, he said. Al-Nuseirat, one of Gaza Strip's eight historic refugee camps, was the site of stepped-up Israeli bombardment on Saturday. An air strike earlier on a house in the camp killed at least 10 people and wounded many others, according to medics. In its daily update of people killed in the nearly nine-month-old war, the Gaza health ministry said Israeli military strikes across the enclave killed at least 29 Palestinians in the past 24 hours and wounded 100 others.

Google's new generation of flagship smartphone Pixel 9 series is expected to be officially released in mid-August, and the new machine is likely to be equipped with ultrasonic fingerprint recognition technology for the first time to replace the original optical fingerprint recognition. According to core intelligence, Google Pixel 9 series will use the same Qualcomm 3D Sonic Gen 2 ultrasonic fingerprint recognition sensor as the Samsung Galaxy S24 Ultra. This ultrasonic technology under the screen fingerprint sensor is Qualcomm released at the CES2021 conference, compared with the previous generation of solutions, the module thickness is further reduced to 0.2mm, while the scanning area is expanded to 8mm×8mm, that is, the recognition area is increased by 77%. This will also allow users to realize fingerprint recognition without having to point their fingertips 100% accurately at the identification area indicated on the screen.
