A provocative new study reveals the complex effects of the space environment on human health, providing insight into potential damage to blood, cell structure and the immune system. The study focused on SpaceX's Inspiration4 mission, which successfully sent two men and two women into space in 2021 to orbit the Earth for three days and shed some light on the effects of space travel on the human body. The research data, derived directly from the Inspiration4 mission, shows that even a brief trip to space can significantly damage the human immune system, trigger an inflammatory response, and profoundly affect cell structure. In particular, space travel triggered unprecedented changes in cytokines that play a key role in immune response and muscle regulation but are not usually directly associated with inflammation. In particular, the study found a significant increase in muscle factors, which are physiological responses specific to skeletal muscle cells in microgravity, rather than a simple immune response. Although non-muscular tissues did not show changes in proteins associated with inflammation, specific leg muscles such as soleus and tibialis anterior muscles showed significant signs of metabolic activity, especially increased interleukin in the latter, further enhancing the activation of immune cells.

US politicians are advocating for steep tariffs, echoing the protectionist Fordney-McCumber Tariff of 1922. Despite potential international retaliation, risks to global economic rules and a shift from post-World War II principles, US politicians have promised to increase trade barriers against China, causing concerns for the sustainability of global economic harmony. A century ago, the Republican Congress passed the Fordney-McCumber Tariff of 1922. This post-World War-I effort to protect the US from German competition and rescue America's own businesses from falling prices sparked a global wave of tariff hikes. While long forgotten, echoes of Fordney-McCumber now reverberate across the US political landscape. Once again, politicians are grasping the tariff as a magic talisman against its own economic ills and to contain the rise of China. The Democratic Party of the 1920s opposed tariffs, because duties are harmful to consumers and farmers, but today both President Joe Biden and former President Donald Trump favor national delivery through protectionism. Trump promised that his second term, if elected, would impose 60-percent tariffs on everything arriving from China and 10-percent tariffs on imports from the rest of the world, apparently including the imports covered by 14 free trade agreements with America's 20 partners. He initially promised 100-percent tariffs on electric vehicles (EVs), but when Biden declared that he was hiking tariffs on EVs from China to 100-percent, Trump raised the ante to 200-percent. On May 14, 2024, the White House imposed tariffs ranging from 25 percent (on items such as steel, aluminum and lithium batteries) to 50 percent (semiconductors, solar cells, syringes and needles) and 100 percent (electric vehicles) on Chinese imports. US government officials offer "national security" and "supply chain vulnerability" as the justification for levying high tariffs. To deflect worries about inflation, US Trade Representative Katherine Tai declared, "first of all, I think that that link, in terms of tariffs to prices, has been largely debunked." Contrary findings by the United States International Trade Commission and a number of distinguished economists, as well as Biden's own 2019 statement criticizing Trump's tariffs - "Trump doesn't get the basics. He thinks tariffs are being paid by China… [but] the American people are paying his tariffs" - forced Tai's office to wind back her declaration. The fact that prohibitive barriers to imports of solar cells, batteries and EVs will delay the green economy carries zero political weight with Trump and little with Biden. Nor does either of them worry about the prospects of Chinese retaliation and damage to the fabric of global economic rules. Historical lessons - unanticipated consequences of the foolish Fordney-McCumber Tariff of 1922 and the Smoot-Hawley Tariff of 1930 - are seen as irrelevant by the candidates and their advisers. The US' lurch from its post-World War II free trade principles offers China a golden opportunity. On the world stage, China will espouse open free trade and investment. China will encourage EV and battery firms to establish plants in Europe, Brazil, Mexico and elsewhere, essentially daring the US to damage its own alliances by restricting third country imports containing Chinese components. Whether the fabric of global economic rules that has delivered astounding prosperity to the world will survive through the 21st century remains to be seen. Much will depend on the decisions of other large economic powers, not only China but also the European Union and Japan, as well as middle powers, such as Australia, Brazil, Chile, ASEAN and South Korea. Their actions and reactions will reshape the rules of the 21st century. If others follow America down this costly path, the world will become less prosperous and vastly more unpredictable. If they resist, the US risks being diminished and more isolated. The author is a non-resident Senior Fellow at the Peterson Institute of International Economics. bizopinion@globaltimes.com.cn

Apple is giving the Apple Watch a major update for its 10th anniversary. The watch's display will be larger, and the entire device will be thinner and lighter. Both the Apple Watch Series 10 and the new Apple Watch Ultra 3 will be equipped with new chips, which may be paving the way for future Apple AI capabilities. According to sources, the Apple Watch health detection function has encountered some technical obstacles in the upgrade process, the blood pressure measurement function or can only realistically display fluctuations and cannot display values, and the sleep apnea detection and other functions can not appear on the new product. The shell material of Apple Watch SE series products may be replaced by hard plastic from aluminum shell. The plastic-clad Apple Watch may be sold at a lower price to compete with Samsung's cheapest Watch, the Galaxy Watch FE. In addition, Siri's new features may be delayed, and AirPods with cameras may arrive in 2026.

TOKYO, July 9 (Reuters) - Russia's deepening military cooperation with North Korea has underlined the need for Japan to forge closer ties with NATO as regional security threats become increasingly intertwined, Prime Minister Fumio Kishida told Reuters. In written remarks ahead of his attendance at a NATO summit in Washington DC this week, Kishida also signalled concern over Beijing's alleged role in aiding Moscow's two-year-old war in Ukraine, although he did not name China. "The securities of the Euro-Atlantic and the Indo-Pacific are inseparable, and Russia’s aggression against Ukraine and its deepened military cooperation with North Korea are strong reminders of that," Kishida said. "Japan is determined to strengthen its cooperation with NATO and its partners," he added. The world, the Japanese leader said, should not tolerate attempts by some countries to disrupt the established international order and reiterated a warning that Ukraine today could be East Asia tomorrow. He also urged cooperation to confront new security threats that transcend geographical boundaries, such as cyber-attacks and conflicts in space. The U.S. and its allies have accused Pyongyang of providing ballistic missiles and artillery shells that Russia has used in its war in Ukraine and say they fear Moscow in return could provide support for North Korea's nuclear missile development. Washington has also said China is supplying droneWithout naming China, Kishida told Reuters "some countries" have allegedly transferred dual-use civilian-military goods to Russia which has served "as a lifeline" for its Ukraine war. "It is necessary to grapple with such situations in a multi-faceted and strategic manner, taking a panoramic view that considers the full range of international actors fuelling Russia’s attempt to change the status quo by force," he said. "The geographical boundary of 'Euro-Atlantic' or 'Indo-Pacific' is no longer relevant in safeguarding global peace and security. Japan and Indo-Pacific partners can play a great role for NATO allies from this perspective." Constrained by decades of pacifism, Tokyo has been reluctant to supply lethal aid to Ukraine. It has, however, provided financial aid to Kyiv, spearheaded efforts to prepare for its post-war reconstruction, and contributed to NATO’s fund to provide Ukraine with non-lethal equipment such as anti-drone detection systems. Tokyo has also repeatedly warned about the risks of a similar conflict emerging in East Asia, where China has been taking an increasingly muscular stance towards its territorial claims including the democratic island of Taiwan. "This summit is a critical opportunity for Japan, the U.S., and the other NATO allies to confront the ongoing challenges against the international order and to reaffirm values and principles that have shaped global peace and prosperity," he said. There may be limits, however, over how far NATO members are prepared to go in forging closer ties in Asia. A plan that surfaced last year for NATO to open a liaison office in Japan, its first in Asia, was blocked by France and criticised by China. and missile technology, satellite imagery and machine tools to Russia, items which fall short of lethal assistance but are helping Moscow build its military to sustain the Ukraine war. Beijing has said it has not provided any weaponry to any party.

July 9 (Reuters) - Lucid Group (LCID.O), opens new tab will recall about 5,251 of its 2022-2023 Air luxury sedans due to a software error that could cause a loss of power, according to a notice from the U.S. National Highway Traffic Safety Administration published on Tuesday. The regulator added the EV maker will also recall about 7,506 of its 2022-2024 Air luxury sedans due to an issue with a coolant heater that could fail to defrost the windshield. Lucid had released an over-the-air software update in June as a fix for the software error and a separate update to identify a high voltage coolant heater failure and provide a warning to the drivers of the affected vehicles. The company had reported second-quarter deliveries above market expectations on Monday, as price cuts helped boost demand for its luxury electric sedans.
