A couple of days ago, a Quad summit meeting in Sydney scheduled for May 24 was abruptly canceled. The US president had to pull out of his long-anticipated trip to Australia and Papua New Guinea. Instead, the heads of the four Quad member states got together on the margins of the G7 Summit in Hiroshima on May 20. The main reason for the change of plans was the continuous struggle between the White House and Republicans on the Hill over the national debt ceiling. If no compromise is reached, the US federal government might fail to meet its financial commitments already in June; such a technical default would have multiple negative repercussions for the US, as well as for the global economy and finance at large. Let us hope that a compromise between the two branches of US power will be found and that the ceiling of the national debt will be raised once again. However, this rather awkward last-minute cancellation of the Quad summit reflects a fundamental US problem - a growing imbalance between the US geopolitical ambitions and the fragility of the national financial foundation to serve these ambitions. The Biden administration appears to be fully committed to bringing humankind back to the unipolar world that existed right after the end of the Cold War some 30 years ago, but the White House no longer has enough resources at its disposal to sustain such an undertaking. As they say in America: You cannot not have champagne on a beer budget. The growing gap between the ends that the US seeks in international relations and the means that it has available is particularly striking in the case of the so-called dual containment policy that Washington now pursues toward Russia and China. Even half a century ago, when the US was much stronger in relative terms than it is today, the Nixon administration realized that containing both Moscow and Beijing simultaneously was not a good idea: "Dual containment" would imply prohibitively high economic costs for the US and would result in too many unpredictable political risks. The Nixon administration decided to focus on containing the Soviet Union as the most important US strategic adversary of the time. This is why Henry Kissinger flew to Beijing in July 1971 to arrange the first US-China summit in February 1972 leading to a subsequent rapid rapprochement between the two nations. In the early days of the Biden administration, it seemed that the White House was once again trying to avoid the unattractive "dual containment" option. The White House rushed to extend the New START in January 2021 and held an early US-Russia summit meeting five months later in Geneva. At that point many analysts predicted that Biden would play Henry Kissinger in reverse - that is he would try to peace with the relatively weaker opponent (Moscow) in order to focus on containing the stronger one (Beijing). However, after the beginning of the Russia-Ukraine conflict, it became clear that no accommodation with the Kremlin was on Biden's mind any longer. Still, having decided to take a hard-line stance toward Moscow and to lead a broad Western coalition in providing military and economic assistance to Kiev, Washington has not opted for a more accommodative or at least a more flexible policy toward Beijing. On the contrary, over last year one could observe a continuous hardening of the US' China policy - including granting more political and military support to the Taiwan island, encouraging US allies and partners in Asia to increase their defense spending, engaging in more navel activities in the Pacific and imposing more technology sanctions on China. In the meantime, economic and social problems within the US are mounting. The national debt ceiling is only the tip of an iceberg - the future of the American economy is now clouded by high US Federal Reserve interest rates that slow down growth, feed unemployment and might well lead to a recession. Moreover, the US society remains split along the same lines it was during the presidency of Donald Trump. The Biden administration has clearly failed to reunite America: Many of the social, political, regional, ethnic and even generational divisions have got only deeper since January 2021. It is hard to imagine how a nation divided so deeply and along so many lines could demonstrate continuity and strategic vision in its foreign policy, or to allocate financial resources needed to sustain a visionary and consistent global leadership. Of course, the "dual containment" policy is not the only illustration of the gap between the US ambitions and its resources. The same gap inevitably pops up at every major forum that the US conducts with select groups of countries from the Global South - Africa, Southeast Asia, Latin America or the Middle East. The Biden administration has no shortage of arguments warning these countries about potential perils of cooperating with Moscow or Beijing, but it does not offer too many plausible alternatives that would showcase the US generosity, its strategic vision, and its true commitment to the burning needs of the US interlocutors. To cut it short, Uncle Sam brings lots of sticks to such meetings, but not enough carrots to win the audience. In sum, US foreign policy under President Joe Biden reminds people of a very advanced and highly sophisticated smartphone that has a rather weak battery, which is not really energy efficient. The proud owner of the gadget has to look perennially for a power socket in order not to have the phone running out of power at any inappropriate moment. Maybe the time has come for the smartphone owner to look for another model that would have fewer fancy apps, but a stronger and a more efficient battery, which will make the appliance more convenient and reliable.

A children's hospital in the Ukrainian capital was hit by a Russian missile on Monday as part of a wave of airstrikes across Ukraine that has killed at least 31 people and injured 154 others. "Russian terrorists have once again launched a massive missile attack on Ukrainian cities - Kiev, Dnipro, Kryvyi Rih, Slaviansk, Kramatorsk," said Ukrainian President Volodymyr Zelenskyy. Zelensky said Russia fired more than 40 missiles of different types at the five cities in daytime attacks, hitting residential buildings and public infrastructure. The Ukrainian air force said it intercepted 30 missiles. Authorities said the attack on Kiev killed seven people, while the attack on Kryvyi Rih, Zelensky's birthplace in central Ukraine, killed 10 and injured 47. United Nations Secretary-General António Guterres condemned the attacks, calling the assault on the Kiev hospital and another medical facility in the capital's Dniprovsky district "particularly egregious," said his spokesman, Stephane Dujarric. "Direct attacks on civilians and civilian objects are prohibited under international humanitarian law. Any such attacks are unacceptable and must cease immediately," Dujarric said. The U.N. Security Council will meet Tuesday to discuss the Russian strikes, diplomats said. The Russian Defense Ministry said the strikes targeted Ukrainian defense factories and a military aviation base and were successful. It denied striking any civilian facilities and claimed, without evidence, that photos from Kiev showed the damage was caused by a Ukrainian anti-aircraft missile. Ukrainian Air Force Colonel Yurii Ignat said Russia has been improving the effectiveness of its air strikes by equipping its missiles with enhanced features, including so-called heat decoys that can throw air defense systems off target. In comments sent to The Associated Press, he said the cruise missiles flew low in Monday's attack -- just 50 meters off the ground -- making them harder to hit. Western countries, led by the United States, have provided Ukraine with billions of dollars in arms support. They will hold a three-day NATO summit in Washington starting Tuesday to work out how to reassure Kiev of NATO's strong support and give Ukrainians hope that their country can survive the largest conflict in Europe since World War II. "Today's Russian missile strike that killed dozens of Ukrainian civilians and caused damage and loss of life to Kyiv's largest children's hospital is a horrifying reminder of Russia's brutality," U.S. President Joe Biden said in a statement Monday. "It is critical that the world continues to stand with Ukraine at this important moment and that we do not ignore Russian aggression." Biden said in the statement that he will meet with President Zelensky during the NATO summit in Washington this week "to make clear our unwavering support for Ukraine." Biden continued: "We will join our allies in announcing new measures to strengthen Ukraine's air defenses and help protect their cities and civilians from Russian attacks. The United States stands with the Ukrainian people." Czech President Petr Pavel said the hospital attack was "inexcusable" and he hoped the NATO summit would reach a consensus that Russia is "the greatest threat and we must be fully prepared to deal with it." Zelensky said during a visit to Poland that he hoped the NATO summit would provide Ukraine with more air defense systems. The Ukrainian leader said rescuers were digging through the rubble of the Ohmatdit Children's Hospital in Kyiv and that the number of casualties was not yet known. Kyiv Mayor Vitali Klitschko said at least 16 people were injured, including seven children, and the attack caused a two-story wing of the hospital to partially collapse. Doors and windows were blown off the hospital's 10-story main building, and the walls were charred. The floor of one room was splattered with blood. Hospital officials said the intensive care unit, operating room and oncology department were damaged.

The Ukrainian presidential office said on July 8 local time that Russia's large-scale attacks on many parts of Ukraine have killed 36 people and injured 140 others. According to the Ukrainian State Emergency Service, a total of 619 rescue workers and 132 equipment participated in the rescue work across Ukraine that day. Ukrainian President Zelensky said on social media on the 8th that Russia launched more than 40 missiles of various types at Ukraine that day. Residential buildings and infrastructure in many cities in Ukraine were damaged in varying degrees of attacks, and a children's hospital was destroyed. Rescue departments are currently conducting emergency rescue on the scene. The Russian Ministry of Defense issued a statement on the 8th local time saying that Ukrainian officials' claim that Russia used missiles to attack Ukrainian civilian facilities was untrue. The damage suffered by Kiev was caused by the fall of missiles launched by the city's air defense system.

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%.

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.
