Xinjiang scientists discover plant with potential to survive on Mars

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.

China will reach climate goal while West falls short
There has been constant low-level sniping in the West against China's record on climate change, in particular its expansion of coal mining, and its target of 2060 rather than 2050 for carbon zero. I have viewed this with mild if irritated amusement, because when it comes to results, then China, we can be sure, will deliver and most Western countries will fall short, probably well short. It is now becoming clear, however, that we will not have to wait much longer to judge their relative performances. The answer is already near at hand. We now know that in 2023 China's share of renewable energy capacity reached about 50 percent of its total energy capacity. China is on track to shatter its target of installing 1200GW of solar and wind energy capacity by 2030, five years ahead of schedule. And international experts are forecasting that China's target of reaching peak CO2 emissions by 2030 will probably be achieved ahead of schedule, perhaps even by a matter of years. Hitherto, China has advisedly spoken with a quiet voice about its climate targets, sensitive to the fact that it has become by far the world's largest CO2 emitter and aware that its own targets constituted a huge challenge. Now, however, it looks as if China's voice on global warming will carry an authority that no other nation will be able to compete with. There is another angle to this. China is by far the biggest producer of green tech, notably EVs, and renewable energy, namely solar photovoltaics and wind energy. Increasingly China will be able to export these at steadily reducing prices to the rest of the world. The process has already begun. It leaves the West with what it already sees as a tricky problem. How can it become dependent on China for the supply of these crucial elements of a carbon-free economy when it is seeking to de-risk (EU) or decouple (US) its supply chains from China? Climate change poses the greatest risk to humanity of all the issues we face today. There are growing fears that the 1.5-degree Celsius target for global warming will not be met. 2023 was the hottest year ever recorded. Few people are now unaware of the grave threat global warming poses to humanity. This requires the whole world to make common cause and accept this as our overarching priority. Alas, the EU is already talking about introducing tariffs to make Chinese EVs more expensive. And it is making the same kind of noises about Chinese solar panels. The problem is this. Whether Europe likes it or not, it needs a plentiful supply of Chinese EVs and solar panels if it is to reduce its carbon emissions at the speed that the climate crisis requires. According to the International Energy Authority, China "deployed as much solar capacity last year as the entire world did in 2022 and is expected to add nearly four times more than the EU and five times more than the US from 2023-28." The IEA adds, "two-thirds of global wind manufacturing expansion planned for 2025 will occur in China, primarily for its domestic market." In other words, willy-nilly, the West desperately needs China's green tech products. Knee-jerk protectionism demeans Europe; it is a petty and narrow-minded response to the greatest crisis humanity has ever faced. Instead of seeking to resist or obstruct Chinese green imports, it should cooperate with China and eagerly embrace its products. As a recent Financial Times editorial stated: "Beijing's green advances should be seen as positive for China, and for the world." The climate crisis is now in the process of transforming the global political debate. Hitherto it seemed relatively disconnected. That period is coming to an end. China's dramatic breakthrough in new green technologies is offering hope not just to China, but to the whole world, because China will increasingly be able to supply both the developed and developing world with the green technology needed to meet their global targets. Or, to put it another way, it looks very much as if China's economic and technological prowess will play a crucial role in the global fight against climate change. We should not be under any illusion about the kind of challenge humanity faces. We are now required to change the source of energy that powers our societies and economies. This is not new. It has happened before. But previously it was always a consequence of scientific and technological discoveries. Never before has humanity been required to make a conscious decision that, to ensure its own survival, it must adopt new sources of energy. Such an unprecedented challenge will fundamentally transform our economies, societies, cultures, technologies, and the way we live our lives. It will also change the nature of geopolitics. The latter will operate according to a different paradigm, different choices, and different priorities. The process may have barely started, but it is beginning with a vengeance. Can the world rise to the challenge, or will it prioritize petty bickering over the vision needed to save humanity? On the front line, mundane as it might sound, are EVs, wind power, and solar photovoltaics.

South African rand stable as markets await US interest rate hints
JOHANNESBURG, July 9 (Reuters) - The South African rand was little changed in early trade on Tuesday, as markets awaited the Federal Reserve chair's testimony in Washington and U.S. June inflation data for clues on the country's future interest rate path. At 0644 GMT, the rand traded at 18.1300 against the dollar , near its previous close of 18.1175. "The rand has opened marginally softer at 18.13 this morning, and we expect trading to remain range-bound in the short term," said Andre Cilliers, currency strategist at TreasuryONE. Markets will listen to the tone of Fed Chair Jerome Powell's testimony in Washington on Tuesday and Wednesday and look to June inflation data out of the U.S. later this week for hints on the future interest rate path in the world's biggest economy. "Analysts will be gauging the Fed's response to the recent softer U.S. economic and labour data, with markets already starting to price in two rate cuts this year," Cilliers added. The risk-sensitive rand often takes cues from global drivers like U.S. economic policy in the absence of major local factors. South Africa's benchmark 2030 government bond was slightly stronger in early deals, with the yield down 1 basis point at 9.74%.
Amid rising regional tensions, the US announced that it will hold another Rim of the Pacific military exercise
The U.S. Navy's Pacific Fleet announced on Wednesday (May 22) that the 2024 Rim of the Pacific Exercise (RIMPAC 2024) is expected to take place on June 26, with 29 countries participating in and around the Hawaiian Islands, a larger lineup than the previous exercise in 2022. The Philippines, which has had multiple maritime conflicts with China recently, and Japan, which has tense diplomatic relations with China, will send troops to participate. China has been excluded from participating in the international military exercise since 2018, and its aggressive actions and reactions are causing tensions in the Pacific region to continue to rise. The biennial Rim of the Pacific military exercise is the world's largest international maritime exercise. The U.S. Navy said that the exercise will last until August 2, and it is expected to involve 29 countries, 40 surface ships, 3 submarines, 14 countries' army forces, more than 150 aircraft and more than 25,000 personnel. The U.S. Navy said that the theme of the 29th RIMPAC 2024 is "Partners: Integrated and Ready", emphasizing inclusiveness as the core, promoting multinational cooperation and trust, and using military interoperability to achieve their respective national goals to strengthen integrated and ready alliance partners. Its goal is to "enhance collective strength and promote a free and open Indo-Pacific region" through joint training and operations. The 29 countries participating in the exercise this year include Australia, Belgium, Brazil, Brunei, Canada, Chile, Colombia, Denmark, Ecuador, France, Germany, India, Indonesia, Israel, Italy, Japan, Malaysia, Mexico, the Netherlands, New Zealand, Peru, South Korea, the Philippines, Singapore, Sri Lanka, Thailand, Tonga, the United Kingdom and the United States. Compared with the 28th RIMPAC held in 2022, which involved 26 countries, 38 surface ships, 4 submarines, 9 countries' army forces, more than 170 aircraft, and about 25,000 officers and soldiers, the number of countries, ships and army forces participating in this exercise has increased. The countries participating in this year's RIMPAC military exercise include all members of the Quadrilateral Security Dialogue (QUAD) between the United States, Japan, India and Australia, and the Australia-UK-US Trilateral Security Partnership (AUKUS), as in the previous exercise. In addition, countries surrounding the South China Sea and the South Pacific island nation of Tonga are also participating. Many analysts believe that the military exercise itself is sending a message to China: China's expansion in the Western Pacific region will be blocked and defeated. The United States invited China to participate in the RIMPAC military exercise twice in 2014 and 2016. In 2018, due to China's expansion in the South China Sea, the United States withdrew its invitation to China. In addition, despite Taiwan's repeated willingness to participate, Taiwan is still not included in the 29 countries participating in this year's RIMPAC military exercise. Analysts pointed out that the US-led RIMPAC military exercise is intended to unite allies to militarily intimidate China. If Taiwan is invited to join, it will be too provocative to China, which will not only aggravate the tension between the United States and China, but also embarrass some allies. The U.S. Navy said the commander of the U.S. Third Fleet will serve as the commander of the joint task force for the exercise, while Chilean Navy Commodore Alberto Guerrero will serve as deputy commander of the joint task force, which is a first in the history of the RIMPAC military exercise. In addition, Japan Maritime Self-Defense Force Rear Admiral Kazushi Yokota will also serve as deputy commander. Other key leaders of the multinational force exercise include Canadian Commodore Kristjan Monaghan, who will command the maritime forces, and Australian Air Force Commodore Louise Desjardins, who will command the air forces. According to the U.S. Stars and Stripes, Vice Admiral Michael Boyle is currently the commander of the U.S. Third Fleet. Vice Admiral John Wade has been nominated to replace Boyle. The U.S. Navy press release said the exercise will enhance the ability of international joint forces to "deter and defeat aggression by major powers in all domains and conflict levels," but did not provide specific information on which exercises will be held this summer. Previous RIMPAC training exercises have included sinking ships at sea with missiles, amphibious landings and the first landing of a Marine Corps Osprey aircraft on an Australian ship.
Musk is the billionaire who lost the most money in the first half of 2024: $5 billion a month
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).
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.
