当马斯克在社交媒体上描绘"20年实现火星自给自足"的蓝图时，一份来自《自然通讯生物学》的研究报告正悄然揭示着更残酷的真相：在国际空间站接受体检的14名宇航员中，100%检测到血液干细胞DNA突变，其中85%的样本携带与白血病直接相关的DNMT3A基因 ...

Scientists compared blood from frequent, long-term donors to that of more seldom ones and saw some key genetic differences in ...

Use precise geolocation data. Actively scan device characteristics for identification. Store and/or access information on a ...

Giving blood regularly may not just be saving the lives of other people, it could also be improving your own blood's health ...

Researchers have discovered genetic mutations in frequent blood donors that may promote the production of healthy cells ...

Men who had given blood more than 100 times in their life were more likely to have blood cells carrying certain beneficial mutations, suggesting that donating blood promotes the growth of these cells ...

But when they looked closer, they noticed that the clones from frequent donors carried mutations distinct from those in the control group, particularly in a gene called DNMT3A (a common area of ...

For example, both sample groups contained clones with changes to a gene called DNMT3A, which is known to be mutated in people who develop leukaemia. Interestingly, the changes to this gene ...

The researchers discovered that frequent donors were more likely to carry specific mutations in two genes called DNMT3A and TET2. These mutations were largely low-risk, meaning they were unlikely ...

Specifically, both sample groups contained clones with changes in the DNMT3A gene, which is known to be mutated in people who can go on to develop blood cancers like leukemia. However ...

Researchers at the Francis Crick Institute have identified genetic changes in blood stem cells from frequent blood donors that support the production of new, non-cancerous cells. Understanding the ...
