Short Wave

A microbiologist explains why we age and die

 

DNA keeps replicating, part of that process means it does get shorter and may miss more and more genetic information.

*helix 나선(형)

On a DNA helix, telomeres are the little ends of the strands.

*chromosome 염색체

*methylation 메틸화 

It's when your body uses methyl groups, which is just CH3, a carbon with three hydrogens, to silence parts of your gene.

In stress, you would increase methylation of your DNA.

*differentiate 분화하다(단순하거나 등질인 것에서 복잡하거나 이질인 것으로 변하다)

Well, as cells differentiate, they don't need all the genes.

*chronological age 실제연령, 생활연령

How much more our bodies have internally aged than our chronological age, which is just like how many years we've been alive.

I'm almost a decade older than you.

*demise [dɪˈmaɪz] 죽음, 사망

Eventually leads to our demise.

*macabre [məˈkɑːbrə] (죽음이나 다른 무서운 것과 관련된) 섬뜩한, 으스스한

+) macabre experiment

*even more so 더욱더, 더욱이

*detrimental 해로운

Even more so, the old blood had detrimental effects on the younger animal.

*sprout up 여기저기 우후죽순처럼/빠르게 생겨나다.

It hasn't stopped companies from sprouting up, selling young blood from young donors.

+) New businesses have been sprouting up all over the city.

+) Mushrooms sprouted up overnight after the rain.

*on one hand 한편으로는

On one hand, obviously, I want people to, like, not suffer from disease, not age super fast.

*evade 피하다, 모면하다

It's also scary to me, how badly people seem to want to evade death and aging.

I mean, it's understandable. It's me too.

There's so many things that I can't control.
