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

goes in cell culture with no gloves, still somehow doesn’t get contamination 

that one insane person who actually enjoys the stress of working with RNA

doesn’t even do SDS-PAGE but still has coomassie stain all over his lab coat 

keeps launching dry ice rockets 

homebrewed a microfluidics system in the lab, it makes weird noises at night and everyone is slightly terrified of it

keeps materialising in the corner of the microscope room when mitsuba is in the middle of taking images. the cause of many a dropped slide.

plots his data in excel

worlds worst file names. no system, no dates, just a keyboard smash and a prayer

who needs desk space when you can just move your laptop into the lab

gave into temptation and tasted the cell culture media once. it was disappointing 

either the most incoherent presentation you’ve ever seen, or a major scientific breakthrough, no inbetween

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.
