The treatment, which scientists hope could stop the progression of MS, involves removing a patient's immune cells, editing the DNA within, and then reinjecting the cells.

科学家希望这种治疗方法可以阻止多发性硬化症的进展，治疗方法包括去除患者的免疫细胞、编辑其中的 DNA，然后再注射这些细胞。

So we scoured the globe and found a start-up that turns polluted water into clean water and clean electricity, by using methane from the process and reinjecting the facility.

因此，我们走遍全球，找到一家初创公司，通过使用过程中产生的甲烷并重新注入设施，将受污染的水转化为清洁水和清洁电力。
