B | 科技创新、科学普及是实现创新发展的两翼，要把科学普及放在与科技创新同等重要的位置。    LAGOS, Nigeria -- The United Nations said it will repatriate nine peacekeepers from a South African contingent in eastern Congo who were accused of sexual assault and other abuse.The U.N. decided to immediately repatriate the peacekeepers and a senior officer of the South African army “due to the seriousness of the allegations against them,” the organization said in a statement on Friday. The senior officer allegedly tried to hinder a probe into the allegations and threatened other peacekeepers. Two other indicted senior officers will also be replaced, the U.N. said. More than 12,000 U.N. peacekeepers are deployed in eastern Congo, where more than 100 armed groups are active. The U.N. said its preliminary assessment found that the nine peacekeepers were “fraternizing after curfew hours” in prohibited bars where prostitution takes place. The soldiers were also alleged to have assaulted staff of the peacekeeping mission and the military police who were trying to arrest them, the statement added.South African authorities have indicated their “full cooperation, in particular through the deployment of a national investigator,” the U.N. said, promising that victims would be assisted and that the peacekeeping mission would remain committed to upholding U.N. standards.Such accusations of sexual abuse by U.N. peacekeepers are not new in various parts of the world, from Congo to Haiti where peacekeepers are deployed. The victims in many instances are children.The abuses are particularly rampant in Congo, which accounted for one-third of the nearly 2,000 sexual abuse and exploitation complaints made against the U.N. worldwide in 2017. The U.N. has also been accused of not doing enough in handling such allegations. Last year, Secretary-General António Guterres said the organization has "not succeeded in all respects, but neither have we stood still” in handling the sexual abuse crisis.。从国务院出台《全民科学素质行动规划纲要（2021—2035）》，到多部门印发《“十四五”国家科学技术普及发展规划》，再到日前这份部署安排，不难看出，科普被摆在了重中之重的位置，被赋予更多关注和期待。相关统计显示，我国公民具备科学素质的比例从2010年的3.2%提升到2020年的10.56%，可谓成就显著。但也要清醒意识到，这一比例跟发达国家相比尚有不小的差距。一说到科普，很多人可能会想到小区里挂几个科普标语，公共场合的橱窗上贴几篇科普短文，以及电视上播放一些科普节目。这些方式不能说没有效果，但已经不能适应时代发展的潮流，难以深入人心。如何更好地提升科普效果？除“鼓励有条件的地区开展全领域行动、全地域覆盖、全媒体传播、全民参与共享的全域科普行动”外，如何践行“注重提升科普能力，运用公众易于理解、接受和参与的方式开展科普”是关键。换言之，科普不是单向输出，而是要强化互动，注重效果。运用公众易于理解、接受和参与的方式开展科普，才能事半功倍。

C | 说到这里，不得不提到“天宫课堂”。2013年6月20日，神舟十号乘组在天宫一号空间实验室开启中国首次太空授课，为全国数千万名中小学生演示了失重环境下独特的物理现象，并进行了天地互动交流。去年12月、今年3月，神舟十三号乘组两度开课。据统计，“航天员老师”们已为全国青少年展示了20个左右的太空实验，有“高度”，接地气，让学生们兴趣盎然，脑洞大开。更重要的是，这种独特的天地互动激发并增添了不少学生对科学的兴趣。据报道，不独神舟十三号乘组，钟南山、张伯礼和李兰娟都曾获得“科普中国最高荣誉”。由此引出一个话题——科普，谁来做？显然，各级科学技术协会要发挥科普工作主要社会力量的作用，各类学校和科研机构也当强化科普工作责任意识，企业、媒体也要尽到应尽的职责。同时，尤其需要广大科技工作者增强科普责任感和使命感。广大科技工作者要发挥自身优势和专长，积极参与和支持科普事业，自觉承担科普责任，同时鼓励和支持老科技工作者积极参与科普工作。当下，一些院士通过视频、直播等形式进行“云科普”，成了科普领域的新“网红”。他们德高望重、腹笥充盈，具有极高科学素养以及丰富经验，化身科普“网红”，效果奇佳。有热情、有能力、有好的方法，这样的科学家投身科普，值得点赞。有科学家说：“我在科普中承担的角色就像一位导游，希望可以通过自己的讲解，激发出网友们对科学的好奇心。”这样的“导游”越多，科普效果就越明显。创新方式方法，多一些走心的科普，增强科普工作的可及性、针对性、感染力，就能进一步激发大众的好奇心、想象力，为建设科技强国夯实基础，为实现高水平科技自立自强提供支撑。（作者：王石川，系媒体评论员）
