Legendary U Washington bookseller Duane Wilkins is drowning in medical debt

Nearly every sf writer who's ever toured the west coast knows Duane - he's the encyclopedically knowledgeable sf buyer for the U Washington Bookseller, who has organized some of the best sf signings in Seattle history. He's a force of nature.

He's also broke. A two-week hospital stay left him drowning in medical debt - despite being insured! - and now he's being threatened by a collection agency.

Now, Duane is forced into participating in one of the most barbaric of contemporary American rituals, fundraising to cover his medical debt. He's raised $6k of the $10k he needs (I just pitched in $100).

If you can afford to help out someone who's done so much for our community, please kick Duane whatever you can spare.

"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

Two-headed tortoise Janus turns 25!

Janus, who also has two hearts, two pairs of lungs and two distinct personalities, would not have survived long in the wild as he cannot retract his heads into his shell to seek shelter from predators. But at the Geneva Natural History Museum, where he hatched in 1997, Bourgoin and her team of carers - who believe he is the world's oldest bicephalic tortoise - can cater for his every need!

He is under constant surveillance in case he flips over, which could be fatal, and survived a bladder stone operation in 2020. His heads need periodic treatment with vaseline to stop them getting sore when they rub together.

His two personalities also generate different moods and tastes that can occasionally lead to conflict, for example over which direction to walk. "The right head is more curious, more awake, it has a much stronger personality. The left head is more passive and loves to eat," Bourgoin said, adding that one head was partial to endives and the other to carrots.

I hate to break it to you guys but vets, doctors, and other medical professionals are not automatically scientists and in fact have to work hard to actually be scientists

They are extremely well trained mechanics for the world’s most complicated machines. Not the same as a scientist.

For example: I know of several young earth creationist doctors

For example: many doctors refuse to follow the evidence we have about obesity, but continue to use their outdated ideas on the topic

For example: my vet always learns something new from me about the science around parrot behavior when I come in with my birds for check ups, and she actually does try to keep up

For example: premed training doesn’t require a scientific major

Saying “a doctor said X” or “a vet said Y” is pretty much meaningless unless said medical professional also does scientific work, which is never guaranteed.

Why do sometimes really weird & unexplainable things kind of happen?

Looking at the Theoretical Intersection between Anatomy & Physiology & Electronics

***This is coming from the perspective of attempting to explain (in the most simple ways possible) how foreign advanced technology possibly “hacks” the foundations of organic life. ***

Our bodies are composed of nerves. When electricity goes from one nerve and travels to another nerve then an action occurs. When something in our environment is sensed (like hearing a noise) our organs are able to sense the information & produce electricity to carry that information back to the brain to be processed.

Anatomically we have the brain, the spinal cord, our sensory organs, cranial nerves, and “all the other individually named nerves” that branch off of those.

(There is further differentiation between central nervous system, peripheral nervous system, & autonomic, and other ways to differentiate in anatomy and physiology, but for simplicity this is how I will refer to it).

Cranial nerves are differentiated out on the list in comparison to “other nerves” because they are a specific list of major nerves that do very important & essential functions in the body.

So, nerves act as a path for electricity to follow. This electricity can produce voluntary action or involuntary actions.

Choosing to raise your hand we consider voluntary action produced by the nervous system. When something occurs without your conscious choice & occurs automatically, it is considered an involuntary action of the nervous system. For example, your heart beating would be an involuntary action.

Nerves have gaps between them & in this space neurotransmitters are released. Neurotransmitters are chemicals with the ability to cause another nerve to have an action. Neurotransmitters have different actions at different places in the body. After neurotransmitters are released they stay in this space until they are broken down by the body. The body breaks down the neurotransmitters and attempts to recycle the components to be used to make other things in the body.

Our bodies are able to use electricity because of many processes, but one major one is because we store electrolytes. Our organs and tissues use electrolytes like Sodium and Potassium to create electrical charge. This “electrical spark” causes electricity to generate so that it can be conducted through the nerves.

The human body is very complex & requires more than just electricity to function due to many components of its design, but each neuron as an individual unit is incredibly similar functionally to wires bundled into computer cables.

How does this process intersect with technology?

If someone were to attempt to hurt you with insidiously with technology it could create A LOT of very weird experiences.

If you know how to electrically stimulate parts of the body, like if you put an electrical stimulator/microchip/or another component that alters electricity in someone’s nervous system you could do a lot of weird things that people with no medical background would struggle to explain.

Machinery causing electrical impulses or “shocks” to be sent to certain part of the brain can produce many effects.

If someone sent electrical impulses down the cranial nerves it would produce a wide range of effects.

If certain cranial nerves were stimulated by someone controlling a technological component then someone could cause your body to involuntarily do the following by stimulating one of the 12 cranial nerves with electricity:

Involuntarily, as if your body moved on its own, you could feel the following:

> Your eyes to move in a certain direction, like your eyes are “locking on” to an object. Similar to how a computer program is able to “lock on” to a target

> Cause your vocal cords to move even when your mouth isn’t open

>Jaw movement & other motions of the face

>cause vertigo/dizziness/altered proprioception or your sense of orientation in space. So a lot of the symptoms of being inebriated

>control of your tongue muscles

> ***Vagus nerve or cranial nerve 10 does a lot, tampering with it could do a lot of weird things *** Possibly weird respiratory and/or internal organ symptoms like shortness of breath, changes in swallowing like dysphagia, vocal hoarseness, & many other possible and serious side effects

> Specific neck movements & turns of the head

You could also produce the sensations in someone of:

>hearing voices that aren’t there or altered processing, they talk but it’s like you can’t understand

>hearing sounds that aren’t there or altered hearing

>seeing images that aren’t there or altered sight

>smelling things that aren’t there or altered smell

>feeling things that aren’t there or altered feeling

>tasting things that aren’t there or altered taste

All of these actions and the degree to which you could “control it” would vary. Some of these are more technically complex to do, but at the most basic level “micromovements” from even just these few nerves are highly likely.

Our bodies have more than just electricity that contribute to our ability to do voluntary control as a defensive system to prevent these types of tampering events from occurring, but I think on a basic level it would still be possible to do some of these micromovements.

Without a lot of technological advancement required, the most worrying to me is a combination of seizures (which can occur when you just overload something with electricity) and/or lots of trauma producing something similar to disassociation & making people hear voices. It unfortunately often produces a mind control like feeling where other people attempt to control and/or influence your behavior.

I think in the quest for mind control, some very bad people use these types of things to hurt other people & technological advancements in subliminal messaging have greatly hurt the world through our time.

In order to fix things I think we must first understand them.
