A | 第20号台风生成，海上“三台共舞” 今天，我们迎来24节气中的第14个节气处暑。进入处暑，通常三伏天已过或接近尾声，今年比较巧，刚好是三伏的最后一天，明天就是出伏的日子。往年这个时候，杭州暑热并未完全消退，最高气温都在30℃以上，甚至出现35℃以上的高温天气。这几天因为下雨的原因，气温不算太高，并未触及高温线，杭州市气象台说，今天我市仍有较明显降雨过程，局部雨量可达大雨级别，最高气温大约在33℃。明天开始雨水逐渐减弱，以午后分散性阵雨或雷雨为主。 Breakthrough new research could significantly increase supply of organs for people with rarer blood types waiting for a transplant, reported The Guardian.,A team of scientists from the University of Cambridge have successfully altered the blood type of three donor kidneys. By flushing blood infused with a special enzyme through a human kidney the scientists removed the blood type markers lining the blood vessels of the organ.,The procedure required using a device that is connected with a donor’s kidney to pass oxygenated blood through it - a normothermic perfusion machine. As a result, the organ was converted to type O, considered the universal donor.,Blood Group Compatible,As the blood type of a donor must be compatible with the recipient’s, the new development could increase the supply of kidneys available for transplant.,A kidney from someone with blood type A cannot be transplanted to someone with blood type B, or visa versa. In such a case, the receiving body’s immune system would reject the new organ, interpreting the different blood type as foreign.,So changing the blood type to the universal O would mean the donor organ could be used for people with any blood type.,“Our confidence was really boosted after we applied the enzyme to a piece of human kidney tissue and saw very quickly that the antigens were removed. After this, we knew that the process is feasible, and we just had to scale up the project to apply the enzyme to full-size human kidneys,” Serena MacMillan, a PhD student at the University of Cambridge, said.,Scientists involved in the research, funded by charity Kidney Research UK and due to be published in the British Journal of Surgery, clarified that the outcome might have particular implications for minority ethnic groups.,Science & TechGood News for ABs: Scientists Can Now Change People's Blood Type21 February, 16:34 GMT,Some blood groups such as O Rh positive and B Rh positive are more prevalent among black, Asian and minority ethnic communities. To complicate matters further, some rare blood types are only found within the black, Asian and minority ethnic communities,This typically places them at a disadvantage, as they struggle to find a match. With low donation rates from these populations, stressed the researchers, sometimes such patients wait for as long as over a year for a compatible donor. They cited figures from 2020-21 showing that just over 9% of total organ donations in the UK came from black and minority ethnic donors. On the other hand, black and minority ethnic patients make up 33% of the kidney transplant waiting list.,“It’s very exciting to think about how this could potentially impact so many lives,” added Serena MacMillan.,The “potentially gamechanging” research was applauded by Dr Aisling McMahon, the executive director of research at Kidney Research UK.,The scientists will now test the reintroduction of other blood types and observe how the novel approach in clinical settings.。虽然和之前的高温天相比，现在的气温已经缓和了许多，但叠加高湿度，闷热感难免，同样要注意防暑。进入8月后，海上的动静几乎没停过。目前有三个台风在活动，天气形势越发复杂，提醒大家随时关注相关信息。台风“简拉维”将给浙江带来风雨昨天，今年第20号台风“简拉维”生成，海上进入“三台共舞”时段（另外两个是第18号台风“沙德尔”和第19号台风“紫檀”）。对浙江影响最大的是最新生成的“简拉维”。据中央气象台，“简拉维”（热带风暴级；英文名称：Gaenari）于昨天下午在西北太平洋洋面上生成，浙江省气象服务中心预计，“简拉维”将以每小时5~10公里的速度向偏西方向缓慢移动，逐渐向浙闽沿海靠近，强度变化不大（或逐渐减弱）。受“简拉维”影响，昨天夜里沿海和浙南地区有阵雨或雷雨，局部暴雨。
B | 23日—25日雨势增大，东南沿海和浙南部分地区有大雨暴雨，局地大暴雨。除了雨还有大风，昨天下午至24日夜里东海中南部部分海域有8~10级局部11级阵风；昨天夜里至25日沿海海面和杭州湾水域有8~10级阵风，建议沿海渔场、海上养殖、渔业捕捞、滨海旅游等做好大风防范。
C | 浙江省气象服务中心提醒，此次台风影响下，东南沿海累计雨量大，并与前期强降雨区重叠，暴雨致灾风险较高，需重点防范可能引发的地质灾害、小流域山洪、城乡积涝等次生灾害。因第20号台风“简拉维”对浙江地区的影响，为确保铁路运输和旅客出行安全，铁路部门计划对8月23日途经杭深铁路G7667次等列车、杭台高铁G7713次等列车，采取临时停运、缩短区段和限速运行等措施。下一步，铁路部门将密切关注台风天气变化，根据风速、雨量和影响程度等实际情况，动态调整列车开行方案，保障旅客安全出行需要。具体列车开行信息，请关注车站公告或致电铁路12306客服热线查询，以便妥善安排行程。“沙德尔”可能升级为超强台风对我国影响较大的还有19号台风“紫檀”。昨天18时，“紫檀”中心位于距离广西东兴市东南方向约65公里的北部湾上，强度为热带风暴级，中心附近最大风力为8级（18米/秒），中心气压992百帕，七级风圈半径100~150公里。预计“紫檀”将原地少动，强度逐渐增强。气象专家提醒，“紫檀”将在北部湾海面长时间滞留，海南、广西、广东、福建等地将有持续性强降雨天气，部分地区累计雨量有一定极端性，需做好提前防御工作。
D | 生成最早的18号台风“沙德尔”目前离我们最远。“沙德尔”昨天14时位于我省东南方向约2800公里的西北太平洋洋面上，当时强度还是台风级，中心位置最大风力13级（40米/秒），最低气压960百帕。
E | 15时中央气象台发布的台风快讯显示，它已经成为强台风级，中心附近风力也达到了14级（42米/秒）。中国天气网此前预测，它可能会在今天升级成超强台风。预计“沙德尔”将以每小时20~25公里的速度向西北方向移动，强度逐渐增强，趋向琉球群岛以东洋面，将于26日前后靠近或进入东海。
F | 后期路径不确定性较大，需持续关注。
