"The researchers have not tested the process on humans, and it’s not clear what dosage of dye or delivery method would be necessary. Human skin is about 10 times thicker than that of a mouse, according to the researchers.

“Looking forward, this technology could make veins more visible, easing … the procedure of drawing blood or administering fluids via a needle — especially for elderly patients with veins that are difficult to locate,” said senior author Guosong Hong, a Stanford assistant professor of materials science, via email.

“Moreover, this innovation could assist in the early detection of skin cancer, improve light penetration for deep tissue treatments like photodynamic and photothermal therapies, and make laser-based tattoo removal more straightforward.”"

Tony's surgeries in the cave: Part 3. Second Surgery

Why the second surgery was necessary: Part 1, Arrhythmia, Reactor, Part 2

What was done:

Removal of the electromagnet.

Sternectomy - partial removal of Tony's sternum.

Removal of some chest and abdominal muscles (some partially, some completely).

Removal of parts of at least 4 ribs on both sides together with parts of attached muscles.

Yinsen may or may not have removed the thymus.

Tony's heart was slightly shifted back in his chest cavity.

Implantation of pacemaker-ICD electrodes running from the bottom of the reactor housing to the heart (This could be done either directly through the chest cavity outside the heart, or through the subclavian vein into the heart).

Removal of parts of Tony's lungs/lungs moved to the sides.

Displacement of blood vessels in Tony's chest.

Displacement or removal of lymph nodes in the chest. In case of removal - replacement with an artificial system connected to the reactor housing.

Implantation of the titanium reactor housing, its attachment to the parts of the sternum that were not removed.

Connecting the housing to the ribs using rib clamps.

Attaching the reactor with the pacemaker to the housing.

Suturing muscles and tendons to the reactor using surgical/biological mesh.

Closing the wound with polyester cuff around the housing where it meets the skin.

Suturing the sternectomy incision.

How do we know this actually happened?

In addition to the reasons stated in Part 1:

After the first surgery, we don't see the reactor housing in Tony's chest. The electromagnet is bolted to the sternum and, unlike the reactor, cannot simply be temporarily removed from the chest.

As you can see below, unlike the electromagnet, the reactor housing is complex, clean, made of titanium and designed specifically for the arc reactor.

Remember about internal organs - you can't just make a hole and put anything in there, no matter how deep it is. You'll need to remove or displace something.

In the scenes below we can see a fresh sternectomy scar after the reactor was implanted. The scar looks different every time, and sometimes it disappears completely thanks to makeup artists. There is not a single scene with this scar before the reactor.

As I mentioned in The Cave timeline (March 1 - April 12), several weeks passed between the successive scenes: Tony finished working on the reactor and showed Yinsen the armor blueprint > the security camera scene and the backgammon scene.

The two weeks between the first surgery and Tony waking up would not have been enough time to recover from the trauma of the reactor implantation. Tony instantly jumps to his feet and is able to raise his arms above his head and hold a car battery - nope, that's absolutely unrealistic.

The Ten Rings would not allow them not to work, but we see them playing board games. Post-op recovery explains it.

people who work/study in quantitative bio-adjacent fields, rise up. computational neuroscience where you get to see someone's thoughts in feelings in graph form??? so cool. biophysics where you can pass blood plasma through an electric field to determine whether a patient has cancer or not?? unbelievable. biomedical engineering where you can literally build a device to pump someone's heart and be the difference between their life and death??? oh my god. disease modelling, being able to predict AND prevent communities being affected by disease on a large scale through your analysis of data??? i love science

Amputees’ hopes to experience the feeling of human touch using their prosthetics are becoming closer to reality. Now, new technology is allowing them to feel temperature—even in limbs that are no longer part of their bodies. For the first time, a functional artificial limb has been fitted with fingertip sensors that allow an ordinary prosthetic hand to sense and respond to temperature just as a living hand does. The device provides a realistic sense of hot and cold in the missing “phantom” hand by delivering thermal information to nerve areas on the amputee’s residual limb that the brain believes are still connected to the missing hand. The MiniTouch, described in a study published Friday in Med, was created with affordable off-the-shelf electronics, requires no surgery and can be fitted to existing commercial prosthetic hands in a matter of hours.

Considering how many blunt and otherwise traumas the Bats take on, Bruce definitely has all of them typed and matched with potential organ donors in Gotham and beyond or has Lucius ready with organs 3D bioprinted out of their own cells (and built on the Watchtower) for use.

Where Does Viktor Fit in Zaun? What Kind of Message will the Herald Bring?

We all know Viktor's headed to Zaun next season, but I've genuinely been wondering what he'll actually do when he gets there. The obvious answer would be that based on previously canon lore Viktor will become the Machine Herald and preach the path toward Glorious Evolution through cybernetic augmentation. But when I look at the state of Arcane, I just can't see that happening. So much of Viktor's story so far has been entwined with his relationship with the arcane and his own mortality which only becomes more complicated as he feeds the hexcore his Shimmer enhanced blood.

While Viktor started out as an engineer, Viktor's work became more associated with a combination of Arcane study and biological experimentation. More often than not, Viktor’s future as the Machine Herald is teased with biological imagery.

When Viktor visits Singed, the equipment that frames him in the shot above is similar to his staff, but more importantly, Rio's silhouette resembles the shape of the Machine Herald's mask. The outline of Rio's body resembles the the 3-pronged shape of the Herald's mask as it appears on Sevika's tarot card. The mask on the card is actually different compared to all of Viktor's existing skins, the three spikes are designed in a way that resembles a crown.

The cave where young Viktor first meets Singed, is covered in holes that resembles thousands of pained howling faces, surrounding both Viktor and Singed. Is it to represent the suffering Singed and/or Viktor will create in the future? Could they represent creatures of the Void, calling out to break free? Maybe the faces represent the already existent suffering of Zaunites who choke and perish in caves similar to the one they stand in?

What's more interesting is that the entrance young Viktor reveals himself to Singed with has the image of ghastly hooded figure carved into it. At first I thought this was supposed to represent inhabitants of the Void. Later, I realized this figure more resembled Zaunites suffering from Shimmer addiction like Huck.

It all feels like the story has been steering Viktor toward Shimmer and the complications of the Void rather than using cybernetics avoid human vulnerability as he did in previous canon. And when you think about Zaun in the context of Arcane, Zaun doesn't need the Machine Herald to promote his augmentations. Cybernetics have already grown in use and popularity in Zaun. After the time skip there's a stark contrast between Vander and Silco's gangs, many members of the latter from Sevika to Ran use augments. It's so prevalent that even members on Piltover's Council know about it. Sure they don't follow the original philosophy of the Glorious Evolution, but Viktor himself doesn't have the foundations for what was originally introduced to League either.

If anything, the visual hints in Arcane lead me to believe that Viktor will become some kind of prophet to the Void. Think about it, so much of what Viktor has done has brought him closer to magic and he's only become further ensnared once Shimmer was involved. From the little that we see of the Shimmer corrupted hexcore, it's likely sentient and it's influence on Viktor will only progress further once he's been completely alienated from Piltovan society.

What does this mean for Zaun though? Well I think Viktor's presence will be a positive presence in the long term for Zaun. The brief moments we see real unobstructed reference to the Machine Herald, hhappens when the design of Viktor's various masks are integrated into the design of the water treatment facility he was implied to have made. The image of the Herald also appears as the the Magician tarot paired with the Death tarot (Jinx) to win Sevika's card game. I previously concluded that the card scene forshadowed that Viktor and Jinx would be the major factors that will win Zaun its independence. On top of that, no matter what universe you stick Viktor in, he fundamentally wants to help others. That drive hasn't stopped in Arcane, and won't stop next season.

Despite Shimmer's justifiably sketchy reputation, it earned it Silco's hope and Singed's interest on it's ability to both sustain life and change it. Outside of being a strength enhancer, Shimmer was shown to effect the rate and longetivity of plant growth in the background of season 1. I think Viktor will be the one to further explore this aspect of Shimmer's effects to make positive impacts in Zaun next season.

I have such confidence because one, Viktor’s research with hexcore and Sky's own note focus on the impact hextech has on biological matter. And two this one shot from Zaun's post-time skip music video.

In the shot above, we see two men with masks and staffs designed in a similar style to the original Machine Herald, stand guard for the building behind them. To the left of these masked men is a sign that reads, "The Herald's Palace". Lofty name aside, what could these men be protecting? If you look into the window behind the two patrons getting their shoes shined you'll notice the outline of broad leaf plants. The masked men are guarding a cultivair! In Zaun, cultivairs are essentially greenhouses only the wealthiest of Zaun can afford to maintain, they're the only sources of fresh air located within Zaun so they have to be well protected. Cultivairs also double as public parks for Zaunites when chembarons want good PR.

The sneakiest possible hint is the design on the wall where "The Herald's Palace" sign is framed, it foreshadows who could have backed Viktor for his rise in prominence in Zaun. It's Jinx. This will make sense, trust me.

First, the swirling patterns of the wall design resemble the smoke cloud tattoo patterns Jinx has around her body. The use of the neon lights in the shot make the swirls appear a similar blue to the real tattoos.

Second, this isn't the only time the artists of Arcane used Jinx's swirly tattoo pattern to refer to her influence. Another time that happened was in the Firelights' music video opening. In the montage, we see bullet casings engraved with cloudy swirls in front of Eve's mask, after Jinx killed her.

Jinx doesn't actually engrave her bullet shells, that's for rich people like the Kirammans. Those engravings are for the audience to know that Jinx was responsible for Eve's death, the early draft even shows the artists were thinking of invoking Jinx's impact by applying her more childish doodles on the shells.

Not only has Viktor and Jinx’s future partnership been foreshadowed more than once in the show, she's the only character outside of Singed I can see betting on Viktor. There's no real reason for Sevika to be interested in Viktor, because when Viktor's reputation is dragged through the mud, even other Zaunites will be wary of him. Sevika also already has a source for her augments in Chembaron Smeech's gang, the Scrap Hackers. What would Sevika want to do with a clearly unstable scientist that not only looks like he's been loyal to Piltover most of his life, but his own experiments killed a fellow Zaunite colleague? How would Viktor not come off any better than Jinx to her?

Jinx will likely be the more empathetic party to Viktor and the disaster he created for himself, she can relate to it. And in related media, like RiotxArcane, he's one of the few people that extends empathy towards her character. She'd be one of the few that probably wouldn't flinch at the line of logic he'll follow in the next season as he continues to double down on the hexcore and the Void. I can only guess, but based on how Viktor reacts in other alternate universes, he'll probably push to further integrate Shimmer into the physiology of its users. Viktor would see it as a means to embrace the necessary change needed to survive the harsh environment of Zaun and the world itself. Who better to pitch such an idea to than one of the more successful Shimmer mutants like Jinx, and probably the extremists who really like her.

Tldr: To understand how Viktor will find his niche in Zaun, we need to understand that Viktor isn't defined by robotics. Viktor's defined by his devotion to helping others no matter how unethical. It's a mixture of his genuine empathy and compassion to those in need, and in his characterization in Arcane, the fact that he sustains his self worth from his ability to create and innovate. So it doesn't matter what kind of world he's placed in, a gothic cowboy world, a psychic soldier battlefield, or a world that worships death he will embrace the most extreme elements of his world and turn it back against the obstacles that put the common people down. Even if his solution is off-putting.

Sidenote: I didn't know where to fit this, but the one concept art that had Viktor's Machine Herald silhouette only further convinced me that Viktor doesn't actually become the Machine Herald like in League.

Thanks to @MPiltovian on twitter for the sketch outline we can see in concept that Viktor's transformation is so stark he looks to be at least a full 2 ft taller. And I know that Arcane's a scifi-fantasy setting, but that's just not how prosthetics work. There's no way that even his full body could support the weight of all that metal, plus a giant laser claw on his back. Viktor probably completely fortified his body using Shimmer and the hexcore to strengthen it and is wearing an exoskeleton on the outside. Honestly, how does anyone single-handedly even turn themself into a full-conversion cyborg anyway?

Saturday, November 11th

Little time lapse of me catching up to my immuno class, and drafting a sociology response. I’ve been wildly unmotivated so I have soooo much to catch up on. Hopefully tomorrow is a more productive day.

[entropicfeline]

they could cook with this…

planet x would probably mitigate a few of these but still, provided planet x isn’t significantly denser than jupiter, the mass discrepancy alone would shake things up quite a bit…

the next few episodes should be interesting 😳

Tony's surgeries in the cave: Part 1. Why there were 2 surgeries

As I mentioned earlier and as suggested in this post, Tony had to undergo two surgeries in the Afghan cave: the first to remove the shrapnel and attach the electromagnet to his sternum, the second to implant the socket for the arc reactor, pacemaker for Tony's heart, and finally the reactor.

We were not shown the second surgery on screen, but there had to be one for the following reasons:

Yinsen did not implant reactor's housing and pacemaker during the first surgery.

Here is the only shot from the movie showing Yinsen inserting the electromagnet into Tony's chest. We don't see the socket for the arc reactor or a huge hole. Because at that time, Yinsen obviously had no plans to place a reactor there. All he did - bolted a shallow electromagnet to Tony's sternum.

Yinsen was not an engineer. Despite what you can read on the MCU fandom wiki page about him, he wasn't "Master Engineer". You don't have to be an engineer to know that electromagnets attract metal. Yinsen was smart, educated, and had extensive experience dealing with shrapnel wounds. That's all. As we see in the movie, he wasn't particularly confident with technology. Under those circumstances, he could not build a pacemaker and an arc reactor housing on his own. You can see how complex it was in that post about reactor. The only person who could do it was Tony. And during the first surgery he certainly wasn't able to build anything.

For all the technology that was implanted into Tony's body, Tony and Yinsen needed a lot of things, such as titanium, a pacemaker or parts to create one, surgical mesh, etc. Unlike rusty electromagnets and car batteries, these things are not found in caves. They had to order it or take from other stuff they were given after the first surgery.

Making things like a pacemaker and the socket takes time. If you are Tony Stark - less time, if you are a biomedical engineer - more time, not an engineer - much more time or eternity. No way Yinsen would have been able to do this before/during the first surgery even if he had all the necessary components.

Tony didn't need a pacemaker during the first surgery. Yinsen didn't mention that something's wrong with Tony's heart itself, that Tony needs a pacemaker or that he implanted one. Something happened to Tony's heart after that, so pacemaker became a necessity, and it was implanted along with reactor.

Complexity of the procedure: as you could see in the post, such a surgery requires serious changes in the patient's chest, affecting the bones, heart, lungs, muscles, nerves, etc. It would require a huge amount of time, a lot of drugs, including a good general anesthetic (chloroform and an awake patient are incompatible with such a procedure), a ventilator, and a lot of recovery time.

You're probably thinking that Marvel made a mistake and forgot about the second surgery, but they just didn't show it for the sake of time and PG-13 rating.
