Thank you so much to the SENS Research Foundation for sponsoring this video!
I asked Triangle Bob to design what he thinks humans will look like in the year
2200. He's been at it for like five hours now so I'm just gonna see what he's done.
For the Love of Animator! What the heck is that? Uh I..I mean Wow, Triangle Bob! They look great!
I see it says here that you've also added super mitochondria to make them live longer? Okay,
we'll have to explore this further! Cue the intro! Hey there! Welcome to Life Noggin!
Turns out Triangle Bob was onto something with his mitochondrial Improvement DLC! A
super small tweak can have a really huge impact on human evolution. Yeah it's a pretty big deal,
but to explain it further we need to travel inside the body let's visit your body's power plant,
shall we? Seat belts everyone! I've always wanted to say that
Oh wow! Here it is the city of mitotropolis! If there's anything you humans remember from
biology class it's that mitochondria is the PowerHouse of the cell, but what does that
really mean? After you digest your food the byproducts make their way into your cells,
and eventually into the mitochondria. Here they are broken down and made into
a chemical called adenosine triphosphate or ATP. This is what your cells use to
store and transport the energy they need to function. Uh oh! This isn't good! That
process created waste products called free radicals! These guys can damage important
parts of your cells like mitochondrial DNA. I mean look at the mess they're making!
Normally when we talk about DNA we mean the DNA in your chromosomes which are located in the cell's
nucleus, but mitochondria are really unique in that they have a small amount of their own DNA,
and I mean a really small amount. There used to be a whole lot more actually, but as humans evolved
the majority of them moved inside the nucleus where it's a lot safer, scientists believe that
the remaining ones are the most essential to the energy production process. For instance
13 of these genes create the chemicals needed to make the wonderful ATP. We have to protect those
guys. So here's the issue happening inside you the beautiful flesh monster watching this video. When
mitochondrial DNA is damaged by free radicals it can delete portions of the genetic code making it
impossible to create these chemicals and make energy, but the mutant mitochondria do keep
making free radicals, which can cause oxidative stress leading to diseases like cancer, diabetes,
and heart disease, as well as aging. Humans disliked that. Now how do we even fix this? While
we can't prevent mitochondrial DNA from getting damaged. scientists are finding ways to keep the
mitochondria working properly by taking Evolution into their own hands! Like the mitochondrial genes
that already migrated to the nucleus on their own, scientists are creating backup copies of
the 13 essential genes in the mitochondrial DNA. They're putting them in the nucleus as well where
they're protected. Don't worry these backups will keep things running smoothly for longer. One group
of researchers has already begun working on this and created backup copies of two of the 13 genes
which they're testing in mice! If this works out we could be seeing dramatic drops in cancer rates,
age-related diseases, and yeah it'll slow down the aging process. Humans liked that.

They're doing amazing work in this field, and they definitely should get your support!
