Feynman's Sprinkler Solved

In graduate school, my advisor introduced us to a particularly vexing fluid dynamical thought experiment known as the Feynman sprinkler. After observing an S-shaped sprinkler that rotated when water shot out its arms, physicist Richard Feynman wondered what would happen if the device were placed in a tank of water with the flow reversed. If the sprinkler was sucking in water, would it rotate and, if so, in what direction? (Image and research credit: K. Wang et al.; via APS Physics) Read the full article

"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

May I ask what the 'no sex in space' rant is? Zero G sounds like fun :<

The space sex rant is my passion. Possibly because I have no emotional investment in the act so when it gets broken down into weird biology and mechanics by the cruel forces of physics, I find it kind of fascinating.

Sticking this below the cut because it will get long. My primary source is Packing for Mars by Mary Roach, but A City on Mars gets into the same issues. Yes, at least two books have entire chapters devoted to the space sex problem.

Note that this is all assuming microgravity. Many of the problems go away if you have artificial gravity, which we haven't cracked yet beyond building centrifuges. Your Star Trek fanfics are safe. So without further ado, and in no particular order, reasons why you probably shouldn't have sex in zero gravity and it probably wouldn't be that fun if you did:

The infamous 'no boners in space'. Since we're evolved to live in gravity, our bodies compensate for it by putting more effort into getting fluids above our heart. In microgravity, that's unnecessary, so you end up with fluid shift - more fluids, including blood, in the upper body. Your total blood volume also goes down. This would make an erection more difficult, and in fact most astronauts interviewed for whom this would be relevant claimed they didn't get any. The outlier here is Mike Mullane, but having read his memoir, he is the kind of guy who would lie about that. Now, as I touched on while despairingly liveblogging Barrayar, that does not prevent you from having a good time. However less blood flow would presumably mean less sensation in general for anyone below the belt. Or if you stimulated too much blood flow, with the lower total blood volume, perhaps that 'got dizzy because I got horny' joke will actually come true.

In microgravity, body heat and CO2 don't disperse the same way they do in regular atmosphere. Astronauts have to make sure they sleep in well-ventilated areas and are also trained on symptoms of CO2 poisoning. If multiple people are in an area exerting themselves, that buildup will happen faster and would need to be taken into account. It would be super embarrassing to suffocate crammed into a closet for some hanky panky.

The laws of motion are not your friend here. I've seen videos of astronauts pushing themselves across the room with a strand of hair. If you're trying to hold onto someone, you'd either want a relatively small space (maybe not a great idea, see point 2) or hold on really well. One astronaut Mary Roach interviewed suggested duct tape. Perhaps fuzzy handcuffs are critical here. Still you're going to need to put a lot of thought into every move you make.

Space is gross. :( Right now astronauts just wipe themselves down with clothes and dry shampoo. "Skin flakes" is a serious problem. Also we're still not entirely sure why, but astronauts develop awful body odor. According to Mary Roach again, while armpits are famous as a BO source, apparently the crotch is as well, it's just that those regions are typically further from our nose. So idk if anyone's going to want to get that close and personal with anyone else while they're up there. Then again I'm sure people have hooked up in grosser situations.

I'm probably forgetting some tidbits since I just woke up, but in summary, zero gravity sex would need to be carefully choreographed, require some equipment (fan, fasteners), and probably wouldn't even be as enjoyable as its Earthnorm counterpart. It's a good thing that's not what anyone's up there for.

Wicked Game

wolverine x vampire!reader

an: set in a timeline where Logan and Alex Summers have beef since i envision this with the days of future past casting!

ch 1

warnings: mentions of blood, needles, generic doctor stuff, cussing i think, angsty lol

ur at the start -- next

~~~~~

The mansion was always having a frenzy. The rotating door of constant students, the random federal agents that never seem to fully go away, and the weird brotherhood that seemed to always succeed in attacking the school and yet never actually hurt anyone. In other words, this was the most fun you have ever had in centuries. The latest fun you ran into at the school was right now. Watching the students frantically try to finish the book report they were assigned by Storm. Listening to their banter and recollection of the book made you giggle at them. Scott Summers, the most vocal of the group, turned to look at you with a scowl on his face.

“Oh like you know anything about, uh, what are we reading?” He said turning back to his friends.

“Dracula?” You inquired, bringing the drink up to your lips.”I was there when it was written.” You smiled. “But don’t expect my help okay? I promised Storm that I wouldn’t say a word.” You walked out of room with a small smirk on your face, listening to their arguing fade.

Humming to yourself, you observed the students on your walk back to your office. As the school nurse, you knew a lot of the students on a first name basis. Many repeat visitors had graced your office with superficial wounds just so they would see you, and your favorite?

Mr. Logan Howlett, the Wolverine himself. Who was sitting on the bench in your office, awaiting your return. Your eyes locked onto his own, and your smile grew, exposing your fangs slightly.

“Well if it isn’t my most needy patient.”

“Guilty as charged,” he muttered standing to greet you. Pulling you into a hug, he squeezed you tight.

“Another day, another blood test?” You inquired, already knowing the answer. Your oldest friend nodded, removing his jacket so you could start to prep his arm for the extraction. Pulling over a stool, you sat as you wrapped the tourniquet over his bicep. “This might hurt”

“You say that everytime.” Logan responded, rolling his eyes and inhaling as the needle entered his skin. “You should train with us again” It was your turn to roll your eyes at him.

“Now you say that everytime,” he huffed at you using his words against him. “I am not who I was a hundred and what? Fifty years ago? I am a doctor, I help people… I am not a vampire.” You muttered the last bit, removing the needle from his arm and taping down gauze. Even though he didn’t need it, it helped him feel human.

You had met Logan around 1899, in the streets of London on the way to America. You both had caused some havoc and needed to escape the city until you had “died”. You both instantly bonded over your mutations and the fact that you both couldn’t die. You certainly had tried, burned at the stake, drowned, stabbed, shot in the head, even a stake to your heart. Your mutation had cursed to you continuously walk to the ends of the earth every time you needed a new identity, and somehow Logan was the same. If it weren’t for the adamantium poisoning his blood.

Holding the vial up to the light, you closed your eyes and focuses on the blood inside. Listening to the way it flowed and coagulated. Reopening your eyes, you stared at the vial until finally, you unscrewed the cap and took a sip. Closing it up, you placed it inside a centrifuge and wiped your mouth of any remains.

“Its so freaky when you do that.” Your rolled your eyes at him. “Especially when you drink it, why don’t you just take it from the source at that point”

“Firstly, I can taste the bourbon you had at lunch. Don’t you know addiction is bad for you? Secondly, I can tell that the serum has been working. I don’t taste the metal as much anymore. You should only need to get three more shots and finish one more round of antibiotics.” You informed him as he put on his jacket. “I love you Lo, but for the love of god please eat a vegetable, I can feel the fat you’ve been consuming.” He chuckled at your request and patted your head. Placing a small kiss on the top of your head, he left your office and shut the door behind him.

Sighing, you turned to start the centrifuge and rested your head on your hand. You hated how he did that. Joked with you and kissed you like you were his world. You knew you weren’t even close to being the owner of his heart. You had tried once, back before the great depression, but he wasn’t interested. He always had his eye on another.

You closed your eyes and let yourself drift away from your thoughts. Enjoying the silence you rarely got.

′′The forces of nature are not separated from each other. They result from a flow of information which under certain conditions give this effect and under other conditions give another effect, but they are not separated.

This space-time circulating like a wormhole generates what we call mass and in the same movement (from the same source) generates gravity. Just as electromagnetism is generated by the centrifugal / radiating force of this dynamics.

We recognize that these effects are the products of one thing, one field, and are not separated even if we study them separately. And we are part of that dynamic. Our existences are the products of this dynamic, from this same source." -Nassim Haramein Buddha Art by Faith Gozenc

Pr and the Mniw

Pr is a minor planet orbiting the millisecond magnetar MMR CHA J1712-2901 ("Ast"), about a thousand light years from Earth, in the constellation Sagittarius. Ast has four major planets: Wsjrhp, Hrw, Mnw, and Bstt. Hrw has one moon, Jmstj. There are five large minor planet in eccentric orbits within 3 AU, Jrb, Bjr, Rrj, Zr, and Pr.

Planetoid

Pr is a large asteroid with a rotation period of about two hours; its average density is less than 4 g/cm^3, but its internal composition is highly variable. About 40% of its solid material is composed of massive diamond fragments fused together at seams formed of carbon glass, and the interior of the planet contains a large irregular cavern roughly 250 kilometers in radius. This cavern is sufficiently enclosed to retain an envelope of water and air with minimal outgassing. Due to the very high rotation speed of the planetoid, the surface of the cavern, at its lower levels, experiences a centrifugal force about 1-2% of Earth's gravity. The axis of Pr's rotation is nearly perpendicular to its orbit.

No complete model of the formation of the Ast system has yet been offered, but several hypotheses have been suggested to account for some of its more unusual features. The formation of a protoplanetary disk may be due to the disruption of a stellar companion, or fallback from the supernova that formed Ast in the first place; the diamond fragments which make up Pr may have originated in a disrupted carbon-rich planet or planetoid, or gas giant. The interior atmosphere of Pr is perhaps due primarily to biological processes releasing volatiles into the cavern.

Deliberate planetary engineering has been mooted as a possibility, but the crew of the DSE Scholiast, the only vessel to survey the system so far, has not yet found evidence of such engineering by other civilizations, and the indigenous inhabitants of Pr are likely incapable of such undertakings at this time.

[Map of Pr, with some regions and bodies of water labelled, plus many major settlements. The relief of the cavern interior is very great; the large plateaus have scarps tens or hundreds of kilometers high. Note that the equilibrium potential at the interior surface of a rotating body is cylindrical, not spherical, and this projection is adjusted accordingly, and so shows true shapes near the poles. The nature of the geological processes that have shaped Pr's interior are not fully understood at this time. The total land area visible here is roughly equivalent to Texas or the Iberian Peninsula.]

Biology and Ecology

Pr's internal heat is maintained by the radiation from Ast, which is converted to thermal energy in Pr's crust. Thinner regions of the crust, particularly near the equator, have higher heat flow from the exterior; the high axial tilt of Pr also means that the northern and southern hemispheres can experience somewhat different heat flows throughout the year. Much more important to Pr's seasons, however, is the variability of Ast's magnetic field created by the eccentricity of Pr's orbit. When Pr is closest to Ast, organisms can extract energy from the magnetic field, as Pr's rotation allows them to create selective ion gradients whose diffusion provides energy, or to directly extract mechanical energy from electrically charged cilia. (Induced current is much too weak to be a useful source of biological energy).

As on Earth, the native lifeforms can be broadly classified into producers and consumers, but even the consumers on Ast obtain a significant portion of their energy budget from autotrophy, using heterotrophy only to supplement this budget. A minority of producers are also radiotrophs, who extract energy from the radioactive elements in Pr's crust.

Pr biology does not use DNA and is highly resistant to radiation. It also does not seem to experience Darwinian genetic drift. Instead, cells seem able to adapt their own internal machinery in response to certain kinds of stress, and to disseminate these changes throughout the organism, or even to conspecifics. The nature of this process and how it could have evolved is still a mystery, nor can they apparently account for all of the different forms observed among the native life.

The interior of Pr is dim, but not dark. Some plant species have evolved to emit light as a form of signaling, incentivizing some animal species to evolve eyes in response.

Because of the energy inefficiency of pure heterotrophy, to say nothing of pure heterotrophy that involves predating on other heterotrophs, no carnivorous animals are known on Pr.

[Above, the Mniw. The upper Mni has a fully-grown set of skin-plates; the lower Mni has either shed or removed hers, possibly as a cosmetic choice. The dark patches of skin shown are the rough beds from which the skin-plates grow.]

The Mniw

The Mniw (singular Mni) are the indigenous inhabitants of Pr. They are 12-18 centimeters long, with tough gray skin, and usually found with a mineralized defensive covering that grows out from the skin. They have a single sex, and reproduce via parthenogenesis. However, they still engage in a form of sexual intercourse, which is divorced from reproduction: instead, sex among the Mniw exists as a means of facilitating horizontal gene transfer, which then alters the nature of the offspring they bear. It can also allow a limited sharing of experiential memory. In addition to sight, hearing, and the other usual senses, the Mniw have the ability to sense the weak induced electrical currents in Pr's crust, which helps them perceive their environment better.

Mniw hatch from eggs and are generally raised in family units; they do not make sex-based distinctions, but do make social distinctions based on relationships. A mwt is the Mni who laid the egg; all other adults in the same household involved in childrearing are jtw; the sntw are siblings who share a mother, while other children raised in the same house are snw. Children from one's own eggs are srtw, while children from one's partner(s) are mnw.

As in humans, Mni adolesence is marked by gradual sexual maturity; reproductive fertility comes later in life, however, around the age of 30. Past 50, fertility declines slowly, as does the capacity to engage in horizontal gene transfer, though the capacity for sexual intercourse remains. Past 65 or so, Mniw enter their equivalent of "old age," but Mni do not experience a sudden collapse in their physiological health late in life, and can in principle life forever so long as they are not felled by accident, violence, or disease. In practice, lifespans are around 130-200 years, with a great deal of variability.

Mniw have many social elements, like hierarchy and emotions and social roles, that would not be entirely alien to humans, but they have no direct analogue to human sex roles or orientations. Instead the major cleavage in Mni society historically is between Mniw who tend to be primarily exogamous, preferring to mate and rear children with Mniw from distant communities, vs Mniw who tend to be primarily endogamous, with about 85% of Mniw being primarily endogamous; these traits perhaps evolved in the context of horizontal gene transfer to take advantage of different patterns of dissemination of useful traits.

Mniw can survive outside of Pr, but without a strong, moving magnetic field must consume a large amount of food; and the food they are normally adapted for will not grow at all absent such a field. An Earth-standard gravitational field would render them totally immobile, and would be extremely unpleasant, though probably not fatal, and it's possible given their unique physiology that they could eventually adapt to such an environment.

Mniw generally inhabit large, almost hive-like cities that are built out in three dimensions; historically, these could be strongly fortified against attack in a way that made wars of conquest nearly impossible until the invention of gunpowder. Mniw have had writing for about 5,000 years, and the first confederate states emerged around 3-4,000 years ago. The dissemination of gunpowder weapons 1,500 years ago radically altered politics and society on Pr, but the absence of easy paths to industrialization has caused a certain degree of stagnation since.

Modern Pr is divided into about a dozen large states, in an area of roughly 750,000 kilometers square, with a fair amount of diversity in languages, cultures, and social systems, given the small size of Pr. A very loose framework of international diplomacy is carried out through a series of councils called the Jaw Mwad, and on the occasion of the Scholiast's arrival, the Mniw convened a great council, a Wr Jaw Mwad, for the first time in over a century to open formal channels of communication.
