A | GENEVA -- After nearly 20 months of waging war in Ukraine, Russia was suspended by the IOC on Thursday for a land grab in sports administration.The International Olympic Committee's executive board imposed the suspension on the Russian Olympic Committee for a breach of the Olympic Charter — a book of rules and principles for international sports bodies — by incorporating sports councils in four regions in eastern Ukraine.Russian Olympic officials provoked the dispute last week by accepting the councils in Donetsk, Kherson, Luhansk and Zaporizhzhia as its members.“(This) unilateral decision,” the International Olympic Committee said in a statement from Mumbai, India, “constitutes a breach of the Olympic Charter because it violates the territorial integrity of the NOC of Ukraine, as recognized by the International Olympic Committee (IOC) in accordance with the Olympic Charter.”The suspension does not immediately affect any Russians who are returning to compete in international sporting events as neutral athletes. However, it did suggest rising frustration from the IOC and its president, Thomas Bach, who can ultimately decide to impose a blanket ban on all Russian athletes from next year's Paris Olympics."(The IOC) reserves the right to decide about the participation of individual neutral athletes with a Russian passport in the Olympic Games Paris 2024 and the Olympic Winter Games Milano Cortina 2026 at the appropriate time,” the IOC said.The Russian Olympic Committee criticized the IOC for “another counterproductive decision with obvious political motivations.”However, the IOC under Bach has often been seen as too sympathetic to Russia during a decade-long doping scandal by never excluding all the country's athletes and teams from any Olympics despite proven allegations of state-backed cheating and tampering with evidence.The latest decision by the IOC board comes seven months after it publicly supported Russian athletes by advising governing bodies of Olympic sports to find ways of including them in qualifying events for the Paris Games.That IOC policy to ease a blanket ban was in defiance of calls from Ukrainian President Volodymyr Zelenskyy and many Ukrainian athletes to maintain the exclusion of athletes from Russia and Belarus.Those vetting processes by different sports will continue despite the IOC suspension imposed Thursday, which does not affect Belarus.“The suspension of the national Olympic committee doesn’t affect in any way the participation of independent athletes,” IOC spokesman Mark Adams said at a news conference after the board meeting.Adams said the Russian Olympic Committee had been informed of its suspension before the IOC announced it publicly.Russia remains excluded from international events in team sports, despite a short-lived and failed attempt this month by European soccer body UEFA to put Russian under-17 teams into qualifying groups for their European Championship.The new ban removes the right of the ROC to get funding from the Switzerland-based IOC, which is worth millions of dollars in each four-year Olympic funding cycle. Russian officials reportedly have been weighing legal action to access the money that was not being paid during the war.The Russian Olympic Committee can challenge the IOC decision at the Court of Arbitration for Sport in Lausanne, Switzerland.“ROC, as a participant in the international sports movement, reserves the right to protect its own interests, as well as the interests of athletes and organizations of a sovereign country, which we represent in good faith,” the Russian Olympic body said.___AP coverage of the Paris Olympics: https://apnews.com/hub/2024-paris-olympic-games。

E | 我们为什么要睡觉？科学家们并不确定，但很明显，睡眠有助于大脑处理记忆，对情绪、注意力和新陈代谢有好处。睡眠也是大脑清理废物的一个机会。睡个好觉的小贴士白天让自己疲惫不堪，保持忙碌和活跃，但在睡觉前放慢速度；避免白天小睡；建立良好的夜间生活习惯，确保你的卧室是放松的，有利于睡眠--厚厚的窗帘或遮光的百叶窗，舒适的室温和床上用品，没有大的干扰，如在床上看智能手机；在接近睡觉时间时减少或消除咖啡因和酒精；如果你不能打瞌睡，不要强迫它或变得沮丧 - 起床做一些放松的事情，如看书，然后在更多的时候回来。如果你的工作是轮班，试着在连续几个晚上的第一次轮班前小睡一会儿，以便过渡。如果你即将结束夜班工作，试着小睡一下，让你度过难关，然后当晚早点睡觉。
