一 |     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.。    8月24日消息，据报道，智能驾驶赛道的人才争夺战正愈演愈烈，奔驰、宝马、大众等海外车企加大在中国的研发布局，开出高额薪资抢夺本土智驾人才，顶尖岗位年薪可达200万元级别。     面对外资的高薪攻势，国内车企不再只比拼现金工资，而是以股权激励锁定核心技术人员，把员工收益与企业长期发展深度绑定。    长城汽车2026年推出限制性股票计划，向1351名管理及技术骨干授予超3198万股股票，授予价格10.03元每股。这份激励设置严苛考核门槛，只有达成对应年度销量、净利润目标，股权才能够解锁，推动核心人员从打工人向事业合伙人转变。    理想汽车也向三名核心高管发放合计3500万份购股权，按授出当日股价折算，市值接近19.9亿港元。这份权益并非直接到手，需要企业港股市值分五档逐级达标才能解锁全部份额，行权还需要高管自行出资，企业发展越好，股权价值才越高。    算上股权收益，国内头部车企核心岗位整体薪酬比外资高出两成至三成五，高管层级的期权预期，让外资的现金薪资优势大幅削弱。    与此同时，外资供应链企业内部出现分化，博世、采埃孚、安波福等企业优化国内智驾相关岗位，不少资深工程师转而加入本土车企，人才呈现反向流动态势。
