Radiation

辐射
Large doses of gamma radiation also harm you by damaging your DNA; radiation poisoning is probably the kind of real-life injury that most resembles Nina's scenario. The cells most sensitive to radiation are, as with chemotherapy, those in your bone marrow, followed by those in your digestive tract.
大剂量的伽马辐射也会对你的DNA造成损害。辐射中毒可能是最接近尼娜设想的情形的现实损害了。和化疗一样,对辐射最为敏感的细胞是你的骨髓,紧随其后的是你消化道中的细胞。
Radiation poisoning, like destroying angel mushroom toxicity, has a latent period-a “walking ghost” phase. This is the period where the body is still working, but no new proteins can be synthesized and the immune system is collapsing.
辐射中毒和“毁灭天使”中毒一样有一段行尸走肉般的潜伏期,在这段时间里你的身体仍然在运作,但无法生产新的蛋白质,免疫系统也在崩塌。
In cases of severe radiation poisoning, the immune system collapse is the primary cause of death. Without a supply of white blood cells, the body can't fight off infections, and ordinary bacteria can get into the body and run wild.
在严重的辐射中毒病例中,免疫系统崩溃是首要致死原因。失去了白细胞供应,身体无力抵御感染,即使是最普通的细菌也能进入体内胡作非为。
The end result
最终结果
Losing your DNA would most likely result in abdominal pain, nausea, dizziness, rapid immune system collapse, and death within days or hours from either rapid systemic infection or systemwide organ failure.
丢失体内全部DNA最有可能造成腹痛、恶心、眩晕、免疫系统迅速崩溃,几天甚至几个小时之内就会因为急性全身感染或全身器官衰竭而死亡。
On the other hand, there would be at least one silver lining. If we ever end up in a dystopian future where Orwellian governments collect our genetic information and use it to track and control us . . .
不过,至少我们还有一线希望。如果我们未来会遭遇反乌托邦的奥威尔式政府,要通过收集人类基因信息来跟踪并控制所有人时:
. . . you'd be invisible.
……你对于他们而言就是隐形的。
1 Yes, “centrifugal.” I will fight you.
1.是的,是“离心”,我要和你斗争到底。
2 I don't have a citation for this, but I feel like we would have heard about it.
2.对此我没有引用信息,但我觉得如果真有人失去了全部DNA,我们肯定都听说了。
3 There are several members of the Amanita genus called “destroying angel,” and - along with another Amanita called “death cap” - they are responsible for the vast majority of fatal mushroom poisonings.
3.鹅膏属里有好几种蘑菇都叫“毁灭天使”,还有一些叫“白毒伞”,全世界绝大多数致命蘑菇中毒事件都由这种蘑菇引起。
4 Citation: I got one of your friends to sneak into your room with a microscope while you were sleeping and check.
4.引用:我让你的一个朋友趁你睡觉的时候溜进你的屋子,拿着显微镜检查了一下。
5 Immune boosters like pegfilgrastim (Neulasta) make frequent doses of chemotherapy safer. They stimulate white blood cell production by, in effect, tricking the body into thinking that it has a massive E. coli infection that it needs to fight off.
5.免疫增强剂培非格司亭(药名Neulasta)可以使频繁的化疗更加安全。这种药物通过诱骗身体相信有大量大肠杆菌感染需要对抗,从而刺激身体生产大量白细胞。
6 Although it's a little different; if you drip superglue on cotton thread, it will catch fire.
6.其实还是有些区别的,如果你在棉线团上滴超级胶水,棉线团会着火。
7 Extremely high radiation doses kill people quickly, but not because of DNA damage. Instead, they physically dissolve the blood-brain barrier, resulting in rapid death from cerebral hemorrhage (brain bleeding).
7.极大剂量的辐射确实能使人快速死亡,但死因不是DNA损伤,而是由于血脑屏障被大量辐射物理解体,最终死于大脑出血。
