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.。本届赛事吸引了来自六大洲、16 个国家的 666 支队伍，共有 2056 台机器人同台竞技，队伍数量较首届增长 138%，机器人数量翻了两番。国际方面，美国、德国、日本等机器人传统强国赛队积极参与，巴西还集结了五支机器人足球世界杯队伍，组建起一支国家联队参赛。

三 | 国内方面，157 家企业、200 所院校和科研机构的 641 支队伍、1975 台机器人齐聚赛场。国内第一梯队企业悉数到场，27 所 985 高校踊跃参赛，产学研用各方力量汇聚一堂。IT之家从官方介绍获悉，今年赛项从首届的 26 项增加至 51 项，其中竞技赛 30 项、场景赛 21 项；比赛场次从 487 场增至 1301 场。在竞技赛中，今年新增的跳远、举重、拔河、乒乓球等高强度对抗项目，都是对机器人大脑、小脑、本体结构以及核心零部件的极限考验。

四 | 赛场上每多跳远 1 厘米、每多举起 1 公斤，都是工程师们对关节电机、减速器不断优化设计、精密加工、测试验证的结果。

五 | 此外，田径场比拼将更加激烈，机器人足球比赛将实现带球跑动、大力抽射等技能提升，更有百支队伍上演“舞林争霸”。本届场景赛则将赛项延伸到真实环境，覆盖工业、酒店、家庭、物流等领域，并专门设置了灵巧手赛项。

六 | 其中，灵巧手设有夹豆子、拧螺丝等 8 个“微操”赛项，上演指尖对决。相比去年场景赛机器人仅“一个人战斗”，本届升级为机器人两两同台比拼，进一步增加赛事的精彩程度和观赏性。
