How to Make a WITCHER with Science

Being a Witcher means walking a path of monsters and magic, but is there a way to make a Geralt of Rivia... for real?

[@DiZeHiZe]

@@Tuxedosnake00 You don't get my point. Nocturnal animal like cats don't require addiational help to see in the dark.

During the fight with the werewolf in his cave, You couldnt see shit without help.

[@howielowis458]

I guess it just further enhances the effect. Think about it, witchers sometimes have to fight in pitch black darkness against opponents that are super fast and/or almost transparent. Under those conditions having anything less than perfect eyesight might prove to be fatal. This implies that the witcher's normal eyes are simply not perfect, so they need the cat potion.

[@dienicy]

[@alphaplayzz1381]

@@DiZeHiZe ah ah ah, nocturnal animals can see in the dark but cats need to see during the day too, their eyes being too sensitive to light would make them useless while the sun is out, the witcher doesn't need the aid of the potions, they just boost his abilities without making a permanent change that could be highly detrimental later.

[@thetimecapsule1680]

While I would love to go into all the cellular biology and genetics gone through this episode, I sadly don’t have the time to do so on my lunch break. I will however talk about a bonus that comes with the increase number of red blood cells. Known as polycythemia, an increase in blood cells does increase the oxygen carrying capacity. Research has shown that those living at high altitudes develop polycythemia as a way to cope with the lower partial pressure of oxygen. So if Geralt has a form of polycythemia (there are several but again no time) he would also be able to retain his stamina and wouldn’t get short of breath at higher altitudes, which would be pretty useful for slaying griffins in their nests atop a mountain. Love the episode, keep up the great work!

[@axeldornelles5292]

I guess that would match his training in Kaher pretty well, as it's a pretty high ways up.

[@CeltKnight]

Excellent point. I look at it from the other side of the coin: I have a form of anemia wherein I produce a LOT of red blood cells but my body essentially eats them, leaving me somewhat anemic (my doc keeps an eye on things and despite what WebMD says, I'm not dying of any horrible disease .. in fact, the cause of my condition is unknown, although it seems genetic, so it's not really harmful, just annoying). In an attempt to maintain health in my fifties, I work out HARD most of the week (CrossFit, martial arts, etc.) which has greatly improved my blood work results. My resting heart rate is in the mid fifty bpm range (like my age, LOL). But if we're doing some especially aerobic stuff (or I decide to outpace the younger ones working out), once my heart rate gets up pretty good, I'm DONE ... can't breathe, muscles worn out, vision might get dim ... but give me a minute to drop my heart rate and I'm as fresh as if I just took a nap. That's my long-winded way of saying I'm looking at the situation from the opposite side and you are totally right. Hmm ... maybe I should move high up on a mountain, force my body to adjust, develop polycythemia which would then edge me over into "normal" range? Darn my choice to live on the coast! ;) LOL!

The only other witcher I remember being white-haired is Ciri. But for normal witchers like Vesemir or Lambert having white hair doesn't seem to be a expected side effect like becoming sterile (which apparently every witcher is, though not 100% certain)

It's clear that tge whole witcher program was sponsored by a king who put together the best alchemists and mages to cone up with the mutation process and the best knights to train the subjects. What is absurd is why the witchers are independent, even if the kingdom that created them fell surely another kingdom would step in and take over. Witchers would perform much better if they operated inside the organization of a royal army. They'd function as rangers, directly paid a stipend by the royal treasure, always equipped with the best gear available and able to rely on the support of the army for missions that required more manpower.

[@ankokuraven]

Hi Kyle, I have another mutation to add, and it fits nicely with what we are already making our witcher out of. Since we are also increasing our witchers musculature and increasing oxygen transportation, there is another adaptation we can give him with regards to oxygen availability. Mammalian musculature contains another heme based oxygen carrying protien called myoglobin. In marine mammals, especially deep sea mammals, this protien is expressed at greater concentrations and acts as a primary means to store oxygen for their long dives. If we add a mutation to this effect to our witcher, there should be more oxygen available before those pumped up muscles have to resort to anaerobic processes, thus increasing the amount he could swing those big guns around before feeling muscle fatigue.

As a graduate student studying red blood cell development in low oxygen, I approve this episode. In fact, EPO production in the kidney is induced by hypoxia sensing protein HIF-2a, which is degraded by PHD2 protein if oxygen levels are high. So if the witcher mutagen damage the EGLN1 gene (which encodes PHD2 protein), they would have more HIF-2a, and so more EPO, and therefore more red blood cells. There are actual clinical cases where patients have mutated EGLN1 gene, and the symptoms include chronic erythrocytosis (over production of red blood cells). In non witcher normal human this is a problem because too much red blood cells make the blood too thick and easily clot in your body. Another interesting fact is that Tibetan populations have a mutation in EGLN1 gene that *enhances* its activity, and therefore produce less EPO even though they are constantly living in low oxygen environment. This prevents frequent blood clotting from chronic erythrocytosis and gave the Tibetan population a selective advantage in highlands.

9:51 - Geralt has to take herbs regularly to keep his side effects in check (unless you played Witcher 1 on the easier difficulty). Herbs, especially ginger, contain anti-oxidants and sometimes even vitamin E that absorb the effects of oxidative stress. Those anti-oxidants are plant-based, which is why the human body sucks at making them on its own. That is why the best course is to keep eating that stuff regularly and with food to minimize the chemical stress of the food. Most of the harmful chemicals come from the food, so minimizing the food effects will help to preserve your genome. If people took more olive oil or ate seeds daily, they could get the vitamin E easily that way.

10:20 ish, just to throw this out real quick: another compelling way to prevent ageing in theory is to find a way to preserve (or prevent the loss of) our telomeres. Telomeres are basically a length of sacrificial DNA. You see, during cell replication, DNA polymerase (the enzyme responsible for copying the original DNA onto the new strand of DNA being made) always leaves out a little bit of DNA at the ends, meaning that that part of your DNA isn't replicated. If that happened under normal circumstances, then you'd lose a lot of information in the form of DNA over time (as your cells divided), and eventually die as a result. Our bodies' solution is telomeres, which are basically just added so that _they_ are the part of DNA that isn't replicated (since they code for nothing, this is neat). It is theorised that over time, our chromosomes' telomeres get shorter and shorter until the vital DNA becomes exposed and the cell dies. This is a small scale ageing mechanism, the prevention of which could theoretically slow ageing down on a cellular level. Cool huh? Loved that we got a Witcher episode btw! Keep up the scienceing!

[@alexandergarfield1561]

Darn, didn't scroll down far enough before I did my comment on telomeres. Yeah and there are other organisms that don't have that reduction process that we have in ours. If I recall we do have a specific mechanism that cuts a little bit of it away every replication and we're working on turning that off cause things like the starfish are basically immortal.... If it's in optimal conditions at all times.

[@mriamthekingofyoutub7736]

well no because telomeres are just rebuilt by telomerase, at least for a long while. long-lived populations have been found to have overexpressed telomerase, but still got "old" at the same rate and just didn't suffer the catastrophic cell failure that the absence of telomeres would cause (exonuclease breaking down the DNA due to exposed ends). the real way to make people be "younger" for longer is more efficient cellular repair by slightly overexpressing the proteins that fix simple mismatches or by making the cells keep extra junk copies of the DNA for so it can be used for homologous recombination which doesn't delete any part of the code instead of non-homologous end-joining which deletes as much as the DNA is broken. also more a more sensitive cell death mechanism is probably needed if the speed is cranked up when healing wounds, which would drastically reduce the chance of cancer. witchers or longer-lived people in general need a system for regenerating damaged nerve cells and cleaning up leftover proteins as to not go senile or get altzheimer's.

Hey Kyle, love the show. Thank you for doing this. First of all, sorry for my bad english, I am brazilian. So, I was thinking about the mutation in witchers that would cause red blood cells to increase, and that probably also explains why witchers have such a lower heart rate (4x lower, as said in the series). The simple act of increasing the number of red blood cells is associated with the increased blood viscosity and decreased cardiac output (which is probably compensated by the increase of the heart sise and "strength", caused by the reduction of myostatin produced). This increased blood viscosity and the overall bigger hearth is related to decreasing the heart rate. This extremely low heart rate, is kind of possible in our world. As in the 1990s, when several high performance road bicycle racing athletes who were doing blood dopping, had a resting heart rate of approximately 34 beats/min (which is comparable to an elephant's) and it was even lower while sleeping. It was so low that they had to set their heart-rate monitor to beep whenever their pulse drops below a certain level. So they can wake up and exercise to increase their heart rate, otherwise they would die. Also, just a fun fact. The witchers super slow heart beat probably makes them less susceptible to poisoning. Keep up with the good show! And sorry again for the bad english.

Hey Kyle, love this show. Thank you for doing what you do. This episode took me back to the dragon fight episode and put my brain down a rabbit hole for a bit. What if the silver sword functions as a sort of poison? Silver isn’t toxic to humans, but if it works as an allergen or even a toxin to monsters, could the silver sword be a way to wear them down as a form of pursuit predation? We already alloy silver with other metals to make it less ductile, because pure silver is very soft. If we went further and alloyed or heated it to be brittle, using this alloy as the edge material of a sword could serve a Witcher well. Each time you struck a monster with your silver sword, small flecks or chips of the edge could become embedded in the wound, and since silver is toxic to monsters, this could cause irritation and inflammation at the very least. So if your prey escapes, by the time you find it again it has been weakened or even incapacitated This would also be why you have to watch weapon durability like a hawk, if your sword is too worn down it is either at risk of breaking or isn’t delivering enough silver to do its job anymore. Thanks again for another great episode and happy new year!

I'm pretty sure that that's exactly what the books say: silver is toxic to most monsters, while some fear meteorite steel, which the witcher's other sword is made of.

Hmmm hmm hmmmm ("hey Kyle, love this show" in Geralt's language) In the show, Geralt mention that Witchers have a lower heartbeat rate than humans helping they to have a longer live and also slowing the effects of a poisoning. Ok cool, BUT, could the fact of the blood flowing slowly in the body make process like oxygen and nutrients transportation inefficients? Make it harder to expell CO2 and other metabolic products that can be toxic to the human body, when in a high concentration? And what about the super healing factor? Cells that help in healing process are transported by the blood, so a slower blood flow would make the whole process take much longer, this contrasts the idea of healing super fast, I guess. Thanks and keep showing to the world how cool science can be!

[@MandaClaudiuMCM]

Usually lower heart beats are associated to people that are fit , athletes and so on .They can have even between 30-40 bpm while resting . A normal person usually has between 65-80 bpm while resting. A fit person with lower bpm can have a heart that is way more effective than a normal person as the heart is stronger and pumps more blood in one beat and therefore more oxygen. So a healthy sporty person with low bpm can have a better blood flow than a healthy person with higher bpm.

Hi Kyle, love the show and thanks for this episode about one of my favorite fantasy genres. Since I´m working on my PhD in chemistry, it kind of got me when you showed oxygen having 7 (valence-)electrons. Elemental oxygen (occuring mostly as O2) has only 6 electrons, making it a double radical. The effect stays the same, but makes Geralt even more impressive :D Keep up the good work and greeting from Germany!

[@alexfm4645]

To be more precise, atomar oxygen has 6 valence electrons. Elemental oxygen, being a molecule out of 2 oxygens, has 12 valence electrons. Due to it's molecular orbitals' energy scheme it has 2 unpaired electrons, forming a double radical. Yet if you have liquid oxygen, a fraction of the oxygen molecules also exist in the form in which all electrons are paired, giving the liquid a slightly blue colour and making it highly volatile. And if you read this Kyle: Heya, amazing show, I love it =). Also greetings from germany, from another dude working on his PhD in chemistry at the time. And since I'm writing now anyway and remembering that once during a live show you were asked why salt decreases the melting temperature of water, I hope that the person asking that question reads this. There are multiple factors for that phenomenon. One is, that a solute, no matter what it is, disturbs the natural crystallization of it's solvent. This also leads to an increase in the vaporization temperature of the solvent, since the chemical potetial of the solution is reduced due to the additive. These are known as colligative properties. Another that is special to salts is that they further disturb the ice structure, because they strongly affect the orientation of hydrogen bridges in the ice structure. On one hand anions, chloride in the case of sodiumchloride, want to ge surrounded by positive (partial) charges, and therefore have the hydrogen atoms of their surrounding watermolecules (also called hydration shell) pointing towards them. The cations, in our case sodiumions, on the other hand want to be surrounded by negative (partial) charges and therefore have the waters' oxygen atoms pointing towards them. The last thing that comes to my mind right now is the size difference of the ions towards watermolecules, which very likely further disturbs the ice structure. I hope that this is comprehensible and that I didn't make any major mistakes. And to emphasize it, I love your show Kyle. Happy new year to all of you! ^^

[@tay012]

Hey Kyle, I’m studying Biotechnology and I wanted to point out that there is a couple problems with decreasing Myostatin levels in a body. In 2007 a paper was published in PNAS of an experiment in mice who produced low Myostatin levels. (Article: Lack of Myostatin results in excessive muscle growth but impaired force generation). 1. So called Double Muscled Cattle who exhibit mutations to the Myostatin gene produce low Myostatin levels. These cows are more prone to muscle damage due to their increase size. 2. The mice were found not to have the correlated strength proportional to the muscle mass. The Witcher would be a beefy boy but not the strength of one.

[@jakubmike5657]

Since you study Biotechnology could you perhaps say a few words about chimpanzee? They are stronger than humans despite being much smaller.

[@erbgorre]

yep, more muscle mass doesnt necessarily mean greater strength. quite the opposite, actually. at least in the specific case of decreased myostatin levels. just one more example for the classic "if one simple mutation could have such a drastically positive effect, it would have happened by now. the fact that it hasnt, should give you pause to think about why that is -.-" argument. i am a vehement subscriber to that school of thought, myself. dont use CRISPR, people. the only thing you might achieve is give yourself cancer. but probably not even that. somewhat similarly, there is also a hard cieling to the benefits of EPO doping, in that systemically increased numbers of red blood cells to way above natural levels will come with considerable drawbacks as well. a much higher general risk of blood clots, for one. and drastically increased danger of heart failiure, especailly when under long periods exertion, due to the increased stress of having to pump blood with significantly higher viscosity. there are cases of professional cyclists dropping dead in the middle of straineous mountain stages from being EPO doped to the gills back in the days when there was alot more unregulated doping going on.

[@tay012]

Jakub Mike, there are a couple differences in the biology that play a role. Humans evolved to walk up right, the extra muscle mass would increase stress on our skeleton. Also compared to Humans Chimpanzees’ muscles have greater proportions of fast fibers that allows for great outbursts of force while Humans have fibers intended for endurance.
