"A team of researchers at Washington University in St. Louis has developed a real-time air monitor that can detect any of the SARS-CoV-2 virus variants that are present in a room in about 5 minutes.

The proof-of-concept device was created by researchers from the McKelvey School of Engineering and the School of Medicine at Washington University...

The results are contained in a July 10 publication in Nature Communications that provides details about how the technology works.

The device holds promise as a breakthrough that - when commercially available - could be used in hospitals and health care facilities, schools, congregate living quarters, and other public places to help detect not only the SARS-CoV-2 virus, but other respiratory virus aerosol such as influenza and respiratory syncytial virus (RSV) as well.

“There is nothing at the moment that tells us how safe a room is,” Cirrito said, in the university’s news release. “If you are in a room with 100 people, you don’t want to find out five days later whether you could be sick or not. The idea with this device is that you can know essentially in real time, or every 5 minutes, if there is a live virus in the air.”

How It Works

The team combined expertise in biosensing with knowhow in designing instruments that measure the toxicity of air. The resulting device is an air sampler that operates based on what’s called “wet cyclone technology.” Air is sucked into the sampler at very high speeds and is then mixed centrifugally with a fluid containing a nanobody that recognizes the spike protein from the SARS-CoV-2 virus. That fluid, which lines the walls of the sampler, creates a surface vortex that traps the virus aerosols. The wet cyclone sampler has a pump that collects the fluid and sends it to the biosensor for detection of the virus using electrochemistry.

The success of the instrument is linked to the extremely high velocity it generates - the monitor has a flow rate of about 1,000 liters per minute - allowing it to sample a much larger volume of air over a 5-minute collection period than what is possible with currently available commercial samplers. It’s also compact - about one foot wide and 10 inches tall - and lights up when a virus is detected, alerting users to increase airflow or circulation in the room.

Testing the Monitor

To test the monitor, the team placed it in the apartments of two Covid-positive patients. The real-time air samples from the bedrooms were then compared with air samples collected from a virus-free control room. The device detected the RNA of the virus in the air samples from the bedrooms but did not detect any in the control air samples.

In laboratory experiments that aerosolized SARS-CoV-2 into a room-sized chamber, the wet cyclone and biosensor were able to detect varying levels of airborne virus concentrations after only a few minutes of sampling, according to the study.

“We are starting with SARS-CoV-2, but there are plans to also measure influenza, RSV, rhinovirus and other top pathogens that routinely infect people,” Cirrito said. “In a hospital setting, the monitor could be used to measure for staph or strep, which cause all kinds of complications for patients. This could really have a major impact on people’s health.”

The Washington University team is now working to commercialize the air quality monitor."

Holy shit. I know it's still early in the technology and more testing will inevitably be needed but holy shit.

Literally, if it bears out, this could revolutionize medicine. And maybe let immunocompromised people fucking go places again

Also, for those who don't know, Nature Communications is a very prestigious scientific journal that focuses on Pretty Big Deal research. Their review process is incredibly rigorous. This is an absolutely HUGE credibility boost to this research and prototype

Clones are real then confirmed. Now the question is are we using this for good or evil?

Why are children dying waiting for transplants when this is possible and you know if it can be done, then they have already been doing it. 🤔

Hey Aby ! I have a question (actually, two) for you regarding bizzare dolls that came into my mind just recently, maybe you’ve answered this question before so i apologize in advance.

Firstly, why do you think the Star Lords exist in the first place ? Like, sure, they “take care” of the blood collecting centers, but what else ? Do you think they have any purpose other than this ? Are they part of something greater ? Because as of now it seems to me they’re actually a waste of energies for Undertaker (like, you know, having to harvest blood for all of them, making sure they’re healthy and don’t lose control…)

Second and last question, why the different blood types ? I’ll explain this better, if Undertaker’s main goal is to keep R!Ciel ‘alive’ why not collecting just Sirius blood and calling it a day ?

I take this opportunity to thank you for being the literal pillar and backbone of our fandom 🫶🏻 who knows what we would be without you ! Lots of love !

⚠️ long post ⚠️

Ok, so I've sort of answered these questions before, but I'll try to be more specific and in depth about it here.

Why the Star Lords to begin with?

There are several parts to this answer, and I'll go into some more details about each one:

The star lords exist because Undertaker wants to bring back real Ciel

Even this part of the answer requires looking at a few different aspects. Real Ciel is one of the star lords, so wanting to bring him back automatically explains why he's one of them. Bringing in other individuals can serve some purposes. Such as:

So real Ciel isn't the only one; he's not alone. It gives him the added bonus of having (loyal) allies to go up against our earl and his allies (particularly Baldo, Mey-Rin, and Finny). These star lords can fight very well (though that might not be the case for real Ciel, since he's apparently only getting AB blood transfusions. More on that later. And he might naturally not be as physically inclined or well-trained). We pretty much have to assume, by now, that Polaris is the one who kills Agni. Real Ciel shooting at Soma (who mistook the shooter for our earl) and Polaris (mistaken for Sebastian, probably) killing Agni turned Soma into an enemy. Much of the star lords' existence seems to be about getting rid of our earl's support system.

The others might end up serving real Ciel in some other way, too, such as collecting blood supplies from the other facilities; we know Vega (Layla/Al) and Polaris are sent off by Undertaker to do that. At some point, real Ciel wants one of them to act as his butler, and later Polaris seems to be filling that role, even though he was away and unable to serve as one earlier. Either way, Polaris identifies as a butler "even in death".

So there's a representative for each major blood type (more on that in part two). That's about religion (or occultism), symbolism, and balance. It's also about scientific research.

The star lords exist because Undertaker wants to make a point to our earl about the choices he makes (which I find very ironic).

Choosing Doll (to represent Canopus) might have something to do with wanting to make our earl feel guilty for her death... if he ever sees her or finds out about her return. We won't know what/how he finds out until we get back to him and he's receiving reports. We aren't quite sure yet who Polaris is, but I suspect he's a former Phantomhive butler, and that could make our earl feel bad about his death, too, even though there was no way for him to prevent it. (Mostly, someone like a former Phantomhive butler for Polaris would be for the fierce loyalty that could be achieved with his "episodes".)

The star lords exist because Yana-san needs to provide more adversity.

Undertaker might also see Doll as someone who could take Snake away from our earl, because of their history. And even if Undertaker doesn't have that in mind, Yana-san sure does; it makes sense from a writer's perspective to have each of our earl's helpers deal with something that exposes their emotions and/or weaknesses. With Doll, Snake feels a sense of belonging, while Finny feels guilt. Layla/Al is good to go up against Lau and Baldo because they likely wouldn't suspect a little girl (by all appearances) to be much of a threat. Polaris is so strong, fast, and flexible that Mey-Rin and Ran-Mao have no idea how lucky they are that they were gone by the time Polaris found out what had happened. Agni and Soma weren't as lucky, dealing with Polaris and real Ciel. 😢

The star lords exist because backers of Aurora Society begged and/or paid to have dead loved ones revived.

At least that's what I think in the case of Layla/Al. I suspect she might be Baron Heathfield's dead daughter. Undertaker agreeing to help restore Heathfield's family might be why Heathfield got involved with Undertaker and the Aurora Society. Not just to find the right "soul shape" for his wife... but also to somehow revive his daughter.

The star lords exist because Undertaker is still curious about humanity (life, death, souls, etc.).

He's continuing to experiment. Even though the main purpose seems to be to revive real Ciel, the effects are much wider in scope. They really are one big series of experiments. Some elements of what he's been working on (possibly with a helper, like Druitt, on the medical aspects):

Manipulating cinematic records. He started out -- probably long before real Ciel was killed -- just adding little snippets of himself to their records, much like the BDs on the ship. He says that when he started working on real Ciel his revival techniques weren't up to snuff (not nonexistent, just not strong enough), so he needed to make quick progress. The others on the ship weren't for that purpose, so they don't really count here. The murders at Weston gave him an opportunity to improve upon record manipulation. And so do the other lords of the stars. This gives him more time to cherry pick which "episodes" to use for each one.

Blood typing and transfusion technology. It is way more advanced (than it should be at this time) because of his work... or the work of whoever is helping him in the lab. It's already led to the development of dialysis machines, too, which brings in another money-making opportunity. The star lords might not have functioning hearts, bone marrow, livers, or kidneys, so the blood transfusions are an ongoing need.

Organ transplants. Experimentation continues with organ transplants, since the orphanage staff mentions something about how hard it is to match the kids up with the star lords based on aptitude. With organ transplants, matching blood type isn't always enough. The personality test doesn't guarantee any more precision, of course, either, but that's not exactly the purpose of that test. Also, transplanted organs don't last forever, even in living humans, so they probably last even less time in a BD. As a star lord wears out their transfused blood, they probably also wear out transplanted organs and other tissues.

Soul transplants. We don't have absolute proof just yet, but I do think Undertaker is also experimenting with transplanting souls into the star lords. On the ship, he says BDs can't do anything with the souls of the people they attack. And he says he can't make souls. However, he hasn't said he can't manipulate souls that already exist; definitely, he has soul manipulation abilities that the BDs lack, and I think he's testing the limits of his own abilities. He's also got Heathfield thinking that he needs to find a woman with a soul the same "shape" as his dead wife's. As I said before, I think Undertaker might be using Heathfield's dead wife as a test subject for soul transplants. I do think he wants to transplant a similar or same-shaped soul into each of the star lords. Either Layla has Al due to one of these experiments... or Undertaker chose Layla to be one of the star lords partly because she already has Al, and Undertaker wants to study this dual personality. His reasoning might go that if he could just transplant the right soul into a star lord, then that star lord would be truly revived... would be able to pump and clean the blood that's been transfused... would be able to make more blood for themselves... would be able to make better use of the organs they've received.

The star lords exist because Undertaker needs a gimmick to lure in people to give blood (whether or not they know that blood is being taken) and for patrons to donate money.

And that's where the different blood types become even more important.

Why the different blood types?

I suppose Undertaker could focus all the efforts on just getting AB "Sirius" blood for real Ciel. But there are benefits to collecting all four types in the ABO blood grouping system (ignoring Rh factor).

AB is rare, and it would still require blood typing a large number of people to figure out who has AB. Hence why they opened Sphere Music Hall and made it a mixing space for all walks of life, placed ads for maids of all backgrounds for Heathfield, offered state of the art medical services for veterans at Athena Sanatorium. and provided a shelter and rare education opportunity for orphans at F. O. L. And people would feel unwelcome if most of them (or any of them, really) were turned away. Making the facilities as inclusive as possible (particularly the music hall and Heathfield's manor) increases the likelihood of getting enough AB blood for real Ciel.

And since Undertaker (and whoever) now also has all this blood for A, B, and O, he should do something with it. By then, probably anticipating the fact that he'd have blood supplies for different recipients, he'd have selected the other three star lords to match the remaining blood types. Each star lord just sort of falls into place, most likely. Real Ciel has AB. "Polaris" is A, so that works. This girl Layla is unusual, plus she's got type O; great, let's bring her on board. And Doll happens to be B; perfect, now all four types are covered.

In the case of Sphere Music Hall, there's also a major occult aspect to it, and having these four portray worshipped individuals works out well to lure people in and gives each visitor a purpose. Even the lesser "stars" that make up the multitudes are useful. Truth is, most of them didn't even know about the star lords; they were too caught up in adoration for the idol singers. Built-in idolatry. Layer upon layer to shroud the star lords in mystery.

For a while, there was so much extra A and O blood that they could also distribute it to renal failure patients who donated money to Aurora Society. Like those old guys in Bath.

There's also the fact that a major truth about the ABO blood grouping system has been, so far, either ignored or misunderstood within the story. When it comes to whole blood transfusions, AB is the universal recipient, so real Ciel doesn't have to "starve" from the scarcity of his blood type. All this time, he could have accepted any of them. It actually all could have been collected for him... from anyone (again, ignoring rh factor). All this trouble to collect AB blood for him could have been avoided, but either the researchers don't yet know this fact, or they know but still aren't making use of it. There is also the possibility that even real Ciel now knows this, but he's refusing anything but AB due to elitist bias. Keep in mind that they have created their own caste system within this "blue cult", despite saying how everyone is welcome and to be treated equally. There's obviously a premium put on Sirius and Canopus. And there've been a few times where individuals talked down to anyone who wasn't amongst the cult's elite and described the vast majority of participants as lesser or "dim" stars.

I'm still waiting for someone (maybe Sieglinde?) to point this out to Undertaker (and whoever is doing the bulk of the blood work). So, part of the reason to have a star lord for each blood type might be to lead up to the revelation that they went through a bunch of completely unnecessary lengths... and to maybe show them that -- for all the knowledge they had -- they still knew so little.

Well, I hope this sufficiently answers your questions. 😂 I feel like I'm forgetting something, but after typing this much, I can't think too clearly about what that might be. 😮‍💨 😅

And thank you so much!! 😊

Wound treatment hydrogel infused with amino acid kills bacteria naturally and promotes cell growth

Hydrogels are popular for use in skin ailments and tissue engineering. These polymer-based biocompatible materials are useful for their abilities to retain water, deliver drugs into wounds, and biodegrade. However, they are complicated to manufacture and not very resilient to external forces like rubbing against clothing, sheets, or wound dressings. They are also not inherently able to battle bacterial infections, so they are often infused with antimicrobial drugs or metal ions, which can cause antibiotic resistance and negative effects on cell growth. In a paper published in APL Materials, researchers created a hydrogel that is easier to synthesize, contains natural antibiotic properties, and promotes cell growth. "A diabetic patient may have skin wounds that do not heal easily due to metabolic disease," author Jing Sun said. "The patient may try to treat the wounds with topical medicines such as erythromycin, and it may be effective at first, but over a long period of time, it may fail to relieve symptoms. This could be due to antibiotic resistance."

Hey all, so the crowdfund is up for ReachAI. If anyone wants to go check it out it would mean a lot to me! Also you can watch the video there on IndieGOGO or here:

youtube

It should give you a bit of an idea on what ReachAI is and what the nonprofit will be doing as well as the benefits of becoming a donor (which there are even more than I talked about in the video including Webinars, 1-on-1 sessions with me, a newsletter update on research the organization is working on or right now that I am). I am excited to be bringing ReachAI closer to launch day, I am really hoping I can raise the money to get it started! I know it could do so much good in the world :3

I hype myself up for my Asian parent-mandated medical-related course by making art for it apparently Fun fact the test tube they’re holding contains culture medium known as a butt-slant (the butt part being the lower flat portion). You stick the inoculating loop with the sample in the butt and you drag it out in a zig-zag pattern over the slant as you pull it out. The more you know (I know you should wear a mask in a bacteriology lab. Shhhh)

I like your idea about Druitt and Unny still in cahoots. It fits well with them both involved in what occurred at Weston. Redmond called on uncle Druitt so he knows the secrets of the Music Hall and the school. And of course none of it would've been possible w/o Unny, and there they both are on the Campania. I never did buy Undertaker's excuse for refusing to reap Druitt or let him be killed. Your idea makes much more sense. Toboso makes us laugh at Druitt so we won't suspect him 2 much, right?

⚠️ long post ⚠️

Undertaker and Druitt connections

I suspect that -- unless they are somehow related, and they might be -- Undertaker first became interested in what Druitt was up to when the viscount began selling off children and young women at auctions, if not sooner (and I'll get to that later in this reply).

If Undertaker was called upon to remove remains from any of the buyers, or from Druitt's estate, he'd want to know what they were doing to those victims/bodies. We know he's picked up remains from Phantomhive Manor on numerous occasions; Sebastian has the other servants pile up the remains from the circus troupe attack and cart them to some back or side gate for Undertaker to collect them. Most likely, this was done whenever there was a failed attack at the manor, even before our "Ciel" became earl and master. The Phantomhives, going back however far they go, would have been common targets to anyone who wanted to get rid of the queen's watchdog. And we know that before other servants were even hired by Sebastian and our earl, assassins and thieves were showing up on a nearly nightly basis. Somewhat regularly, in any case.

We now know quite a bit about how our earl ended up with his current servants, but we've learned very little about how he ended up with his various connections; we don't even know how he connected with Vincent's old, remaining network. I imagine that one of the first reconnections he made (besides Madam Red and Tanaka, of course) would be Undertaker. People would show up to the manor, Sebastian would kill them, and then what? Sebastian would have asked his young master how he wants to dispose of the bodies. At first, our earl might have suggested to bury them on the vast estate. But, as the numbers mounted, this would have taken more time and space, plus it could open them up for investigation, if remains were found (by others) that weren't proper burials in the family cemetery. Another option would be to dump them off the grounds, as far away as possible. This could still become a problem. Our earl would remember the creepy undertaker that popped up around the manor (and possibly also the estate grounds) from time to time, back when his predecessor was in charge. During the instruction both boys received about being earl and watchdog, Vincent might have already explained why he has Undertaker in his network... at least the professional reason, though definitely not the personal reason.

I don't know whether Druitt was ever in Vincent's circle, a member of the evil nobles. They probably attended Weston together, but we don't know if he's the Scarlet House prefect. Either way, Druitt might have actually become a subject for investigation before. There's even a scene during the curry arc that could be a hint to that. The jeweled lady that Druitt recalls might actually be Vincent in drag, at some event years ago, there to investigate Druitt or someone else in attendance.

We have no idea how long ago Druitt started trafficking humans, so perhaps it was related to that... and he just got away to do it again and again... much like we've seen him get away with the things he does while our earl is watchdog. Even when Druitt is arrested, he goes free. Probably bribery to corrupt officials. Some of the higher-up ones might be clients/buyers. Yana-san really drives home how much corruption and fraud and abuse there is in her Victorian England. Sadly, it's not too far from reality.

Doctors were largely detested during the era because of some shady practices that many engaged in. Practitioners would be hired to have people committed to asylums... or even to examine girls to see if they were still virgins, so their families could prostitute them out and charge more for their first assignations. Surgeons (for practice) and anatomists got their human dissection subjects through various means; some were acceptable and others were downright despicable. They prescribed dangerous substances as medicines; sometimes the "cures" really were worse than the conditions.

Though Druitt doesn't have a medical practice, he has a medical license. Before he even got into selling live humans, I wouldn't be surprised if he was involved with supplying and/or buying corpses for study. It would be interesting if Druitt cut out the grave robbers by going straight to undertakers for a supply, because he seems like the sort of person who would do a lot of studying on his own, particularly since he's an aristocrat with no intention of opening a public medical practice. Druitt's connections to Undertaker might go back quite a long way, maybe even back to Druitt's Weston years... when Undertaker would have likely re-entered Vincent's life. Who knows, but I'd be very interested to find out.

When Sebastian investigates all the people with events for the social season, narrowing down the ones that might line up with Jack the Ripper, we don't know where he gets all of his information. It's entirely possible that some of it comes from Undertaker, particularly about people like Druitt. Which supports the idea that Undertaker might already have a history of dealing with the remains of people who have passed through Druitt's doors.

Well, they definitely meet before the events of the Campania, since they already have some sort of dealings with each other, including the Aurora Society. Druitt could easily be the one who introduces Undertaker to Stoker. I very much doubt it would be the other way around, with Stoker making introductions between Undertaker and Druitt.

I'm sure there was more I wanted to get to here, but this reply has been sitting in draft for ages, and I've forgotten whatever else I'd wanted to say. 😬

But Druitt has got to supply more to Undertaker than simply laughter. Knowledge and/or experimentation that leads to medical technology would be very helpful for his current activities.

And we can't ignore the possibility they are also related. Particularly if Undertaker ends up being Cedric K. Rosewood, Rosenthal, Rosedale or any other last name that would make him sound right at home in Scarlet House....
