二 |     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.。如果说是刻意这么说，刻意替3，2亿灵活就业者做一种掩盖和美化，这个事都不值得我去说。

三 | 因为这个人确实是将视线放在了底层，仅仅这一次的说话，并不至于写文章去“挑剔”。但我看了她的表情以及那种发自本真的言语，才不得不说。

四 | 为何？如果真的，在那个层次和段位，能决定下游群众生活决策的人都是这种发自本真的想法，认为灵活就业是一种福利，很幸福，那么这对这3，2亿的灵活就业者来说，未来造就的苦难是致命的。本来一天干活200元，吃喝完，还能有一点余粮，但这个余粮是建立在你后面几天没有活的基础之上的。灵活就业者，一个很可怕的现实是什么？那就是朝不保夕，不稳定，今天可能赚200，但明天就可能颗粒无收，而你那些能决定决策的人，不能只看到灵活就业者的自由度，还要看到朝不保夕这一点。张丹丹教授这个概念如果被扶正，那么这个苦难附加在个体身上，将是沉重的。

五 | 我在园区周边小镇生活，日常中几乎每天都会和“日结工”打交道。

六 | 日结工今天京东物流那里分拣快递，工人做不完，那么找几十个日结工来做活，但这些临时的活一定是最累的。带班的小班长不会给这些可能做一天这一辈子都不会有交集的人一点怜悯，最大的箱子件一定是他们卸货，最脏的包装一定是他们分拣，而且因为是日结，那个时间会被压缩到极致，压缩到喝水的时间都没有。也是因为这个原因，临时失业的人们，干一天日结工，要休息两天才能缓过来。那么，问题来了，如果张丹丹教授们看不到这个苦难，只看到了自由度，未来这一块也要吸血，那么这个血吸得一定是残忍的，是哀嚎遍地，是一种人性最后的一丝泯灭。也所以，我不厌恶张丹丹，我昨天的文章虽然标题有点攻击性，但本质上我害怕的是更多的张丹丹们，而非只是她一人。也所以，我在看到教授这个发自本真的言论后，建议她们这些专家不妨走一走，不说像我这样如苦行僧一样到一个乡镇走上半天，与小镇各种不同的人攀谈，你那怕到县城的还算可以的宾馆，小酒店住两晚，凌晨到菜市场走一圈，中午到那些闲散的工人聚集地看一看，相信你们的思想就会有很大的改变，能切实的看到这本真的人间。谢谢！
