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.。
二 | 中新社新疆阿勒泰8月25日电 （苟继鹏）25日，以“石英铸基 芯疆未来”为主题的2026高纯石英产业链发展大会在新疆阿勒泰市召开，40余位行业专家学者以及180余家产业链上下游企业代表参会。 期间，阿勒泰地区高纯石英产业战略咨询委员会正式成立，阿勒泰高纯石英产业研究院及国家级工程技术研究中心高纯石英示范中心、国家级创新中心高纯石英分中心、全国重点实验室高纯石英中试基地集中揭牌，《阿勒泰地区高纯石英产业发展白皮书》同步发布，标志着新疆高纯石英产业发展正加速从资源储备向工业化应用转化。 高纯石英，被称为新材料领域的“工业基石”，是支撑新能源、半导体、算力、精密光学发展的战略性关键矿产。2025年经中国国务院批准，高纯石英矿被正式列为中国第174号新矿种。 中国工程院院士、中国建材集团首席科学家彭寿在会上称，在中国AI产业加速发展的今天，高纯石英产业的突围显得至关重要。中国需突破技术瓶颈，推动高纯石英从资源勘探到高端制品的全产业链创新，并加快在新兴领域的应用拓展。
三 | 阿勒泰地区地处世界级伟晶岩成矿带，高纯石英资源禀赋得天独厚。在该地区发现的高品质矿源经物理选矿预处理后，二氧化硅纯度可达99.998%（4N8级），品质达到世界一流水平，被业界视为中国发展高纯石英产业的“种子选手”。
四 | 近年来，阿勒泰地区立足本地绿电、矿产资源禀赋，加快打造中国高纯石英产业新高地。目前，当地高纯石英产业正加速从“资源发现”向“产业验证”迈进。
