Not sure what is going on with @HealthcareGlob1 - they sure seem to have it out for @NukitToBeSure.

They blocked me after I pointed out that they were incorrect. I could care less about being blocked.

I do care they did not address the issues I raised. 🧵
They retweeted this tweet from DisabledDoctor, which has numerous issues.

1. FARUVC has been safely
& extensively tested on the eyes. There are a rather large number of studies on the topic.

2. FARUVC will not cause AQ issues, besides a Yup. Not even considering the fact that she recommends using her far-UV devices in ways that are possibly unsafe (pointed at face as they are untested on eyes and in poorly ventilated indoor spaces where it is likely it will cause air quality issues leading to or exacerbating respiratory problems). She's harming vulnerable people while profiting off of them and she seems to give no fucks while somehow managing to get people to aggressively support her when she is (fairly) criticized. She's a master manipulator 8:08 AM 11 Sep 29, 2024 7,975 Views
negligible amount of ozone.

But that's not me saying that, but the studies. Two studies in well sealed rooms - about 5 parts per billion, 5 ppb.

If you are in a well sealed room, you would want that window cracked, anyway, right?

If not, and you are In summary, the two published measurements of far-UVC associated ozone in real-world settings, both around 5 ppb, are likely to be upper limits in terms of real-life far-UVC usage; this is both because of the far-UVC doses used in the studies, but also because both rooms were comparatively well sealed (respectively 0.4 and 1.4 ACH, see Table 1), whereas far-UVC will predominantly be used in public indoor spaces, which typically feature higher air-exchange rates.18 Overall it is reasonable to assume that far-UVC-associated ozone levels in real-life settings are extremely unlikely to exceed 1...
gobbling a quick bite in an airport, not a problem, anyway, (I will only be doing a sipmask and shakes, myself) - the ozone will dissipate.

Guess what gobbles ozone? VOC carbon filters. Hit my account plus MEGA VOC to find the build.

But 5 ppb? I am not worried about it.
But, IS 5 ppb a risk?

No risk as low as 10 ppb per this study...and we are 5 ppb below that, with ways to mitigate even that. In summary, based on multiple very large epidemiological studies focusing on the relationship between outdoor ozone concentration and long-term human health, there is no significant evidence for increased ozone risks at ozone concentrations as low as 10 ppb, and there is persuasive evidence for a threshold in risk at ozone exposures below about 35–50 ppb; this pattern does not change whether or not other associated pollutants are included in the risk estimate. Although far-UVC lamps are not classified as medical devices, the epidemiological results are consistent with current FDA guidelines...
VOCs and ozone? You are right to be concerned - and now not be concerned 👇.

But...cleaning with limonene based cleaners (Citrus King , citrus smelling cleaners probably) ?

Turning off the FARUVC would be a reasonable thing to do.

onlinelibrary.wiley.com/doi/full/10.11…Indoors, at the low induced ozone concentrations of relevance here, ozone does not react rapidly enough with preexisting airborne VOCs to compete with even extremely low levels (e.g., 0.1 ACH) of room ventilation, so significant ultrafine particle production via far-UVC-induced ozone is unlikely. Experimental measurements in a real-life hotel room support this conclusion. One specific exception is the cleaning material limonene, which has an unusually high interaction cross-section with ozone; in the far-UVC context, turning off far-UVC lights during cleaning with limonene products would be...
Is Nukit just trying to just make a buck, taking advantage of the vulnerable?

No - lol. They are a huge influencer.

The vulnerable? They are the reason Nukit started w/UVC, to provide Covid free air to the poor jammed into tiny apartments with no room for CR boxes. Indoors, at the low induced ozone concentrations of relevance here, ozone does not react rapidly enough with preexisting airborne VOCs to compete with even extremely low levels (e.g., 0.1 ACH) of room ventilation, so significant ultrafine particle production via far-UVC-induced ozone is unlikely.

One specific exception is the cleaning material limonene, which has an unusually high interaction cross-section with ozone; in the far-UVC context, turning off far-UVC lights during cleaning with limonene products would be...
Finally, there has been a fair amount of discussion of the picture on the Cybermarket website.

Does it depict closer than 50 cm, which is the safe distance as amply discussed by Nukit?

cybernightmarket.com/products/mini-…Cybermarket 75 cm from faces.
Suggested use: Assuming no more than four hours of use in a single day, and an approximate room size of 9-12m², each lamp should be positioned no closer than 50cm away from a room occupant. The more widely the lamps are spread, the more air volume will be exposed. If there are children or pets present, the lamps should be placed well out of reach. For more information, see: How to use your Nukit Torch Far-UVC Lights
No. It is 75 cm. I DM'd that party.

I am in blue, they are in gray. Unless you are IN your dinner plate with your head, these are about an arm length away from your eyes 10:17 PM 3 feet then? At least 91 cm ? I have some long arms....but I went to be accurate. 10:18 PM Between 2 and 3 feet, so roughly 75cm 10:18 PM Ok, thank you.
Here is more by Nukit.

"... 200nm to 230nm is often described as “eye and skin safe” but is perhaps more accurately described as “safer”. There is still an exposure limit- just much, much higher than with other portions of the UV spectrum." Description: The germicidal properties of ultraviolet light are well established and have been in use for almost 100 years, but that effectiveness has always come at a price- the potential for eye and skin damage. Far-UVC, the portion of the ultraviolet spectrum that ranges from 200nm to 230nm is often described as “eye and skin safe” but is perhaps more accurately described as “safer”. There is still an exposure limit- just much, much higher than with other portions of the UV spectrum.
What are my biases?

I have disagreed with Nukit in the past on a couple of non-technical issues, but these are times fraught with tension.

On the technical issues, I have found them
incredibly knowledgeable, and I very much appreciate their engineering.

Anyone accusing Nukit of endangering others are simply not knowledgeable on the topic.

Do I have a Cybermarket light? No. Do I anticipate getting one? Maybe in the future, if they are still available.
I have other projects I am currently interested in.

Am I an expert in FARUVC? No, but I can sure read a study.

And so can you.

Where can you buy the lights?

@TheAtlantic @danengber Heh - I suspect Mr. Engber has been eavesdropping on my (and my fellow Covid Conscious) swimming safer threads. I have a new solution for showering safer for that I will be rolling out tomorrow.

For future articles by those who will come along, let me point out a few things /+
@TheAtlantic @danengber Thank you very much for pointing out that 4% of America is still masking 100% of the time! That is 13.2 million Americans.

The Masking Nation is larger than 38 states. :)

But, 18% of us masking some of the time in the SAME PEW POLL (tch tch). You would think that would be/+ At a basic level, their COVID-conscious attitudes may not be so far from the mainstream. Twenty-one percent of Americans still think of the disease as “a major threat” to public health, according to a recent poll from Pew Research Center. Thirty-nine percent say we’re not “taking it seriously enough.” But if 50 million to 100 million adults harbor such concerns, very few are doing much about them. Masking rates were once as high as 88 percent; now they’re close to nil. For those who still maintain their masking habit—4 percent, says Pew—the whiplash in social norms has been a shock.
@TheAtlantic @danengber be mentioned, @TaylorLorenz, by Mr. Engber, since 18% lines up pretty closely to the 21% still worried that Covid is a big deal (it is) - that he mentioned.

And suddenly, Masking Nation has 59.4 million residents. We are the largest state. Canada /+

This may be one of the most important studies in a decade.

#LongCovidBinder.

"The models produced correctly classified those with severe ME/CFS from recovered controls with an accuracy of 97%, sensitivity of 94%, and specificity of 100%. "

THAT IS HUGE.
"We found that at Stage 1, those fated to develop ME/CFS 6 months following IM had low levels of IL-5 and IL-13 [25]. " We found that at Stage 1, those fated to develop ME/CFS 6 months following IM had low levels of IL-5 and IL-13 [25]. IL-5 enhances the production of B1 cells which are anti-inflammatory (impaired B1 cells have been found in multiple sclerosis, systemic lupus erythematosus, and rheumatoid arthritis), and IL-13 has anti-inflammatory properties. Jason et al. [26] also found that students who failed to recover from IM had more restricted, inflexible cytokine networks whereas those who recovered had more flexible, less interconnected networks. Network analysis suggests that IL-5 and IL-13 influe...
So, this means ME/CFS can be predicted.

And what can be predicted - treatments can be found.

And they are studying LongCovid as well.

This study is easy to read, And everyone should.

A new study just showed what I have been saying since the start of bird flu. H5N1 is airborne.

Still in place?
USDA: YOU ONLY NEED TO TEST LACTATING COWS.

oops.

USDA: FOMITES (infectious objects) SPREAD IT.

oops.

WASHING YOUR HANDS WILL STOP IT.

oops. This new Federal Order does not override or supersede USDA's April 24 Federal Order, which still requires the mandatory testing of lactating dairy cows prior to interstate shipment and requires that all privately owned laboratories and state veterinarians report positive test results connected with those tests. The new Federal Order announced today is intended to complement and enhance this existing order.
Question [00:51:52] Given the CDC's vaccination program, I'm wondering if this means you think it's no longer realistic to expect that the outbreak will be contained this year? Eric Deeble, USDA [00:52:12] Just on the animal side and all that Dr. Nirav speak to the human side, there's a lot about this disease that makes us feel as if we can arrest its progress. And we've actually seen some success demonstrated to date. With this disease, it does not appear to move by respiratory transmission. We know that there are high viral loads in milk, and we've identified through close, collabora...
In addition to testing, biosecurity is the key to containing this virus, and ultimately ensuring that it is eradicated so that producers do not have to deal with this virus in dairy cattle permanently. Good biosecurity including cleaning and disinfection of vehicle and equipment - is critical to minimizing the risk of disease spread. USDA works closely with state animal health official, producers, and industry organizations to provide guidance and resources for cleaning and disinfection not only on affected farms but for all livestock producers as a part of practicing good biosecurity. APHI...
The study.

✅ 20% of the cows showed up as sick. Had symptoms. But....

✅ It turns out that 89.4% were actually infected.

✅ 83.7% of those had no symptoms. Remind you of any other airborne diseases?

✅ 40.5% of the dry cows not being milked? Infected. So, no Image

There is not much that scares me. Freaks me out.

I am freaking out.

You should be, too.

Do you know what this shows?

Do you know how to avoid this? Holy cow.
This is the continued accumulation of dementia-causing microplastics in your brain. Simple linear regression (shown with 95% CI represented by dashed lines) was performed for total plastics, polyethylene, polypropylene, polyvinyl chloride and styrene-butadiene rubber measured in normal decedent brains from 2004 (average of east coast samples), 2016 and 2024 (NM OMI samples).
See how it increased from 2016 to 2024?

And it actually is worse - they found less plastics in brains from a decade earlier.

Great interview of Ed Yong - I am just covering the C0V1D part.

/1 The Interview Ed Yong Wants to Show You the Hidden Reality of the World Ed standing with his arms folded. His eyes tell you COVID is not over.
You've been clear in saying that C0V1D has not gone away. You ask people to wear masks at your events..... You’ve been clear in saying that Covid has not gone away. You ask people to wear masks at your events. But that attitude is not necessarily where the rest of the world is. How do you think about continuing to take precautions and advising others to do so when it feels as if society has moved on? I do it for a bunch of reasons. Firstly, I have learned that I enjoy not being sick. I know that the cost of long Covid is real and substantial, and I don’t want to run that risk lightly.
"I think it makes a huge difference to them to have the person at the front of the stage wear a mask. It tells them, It’s not weird." . I also know that I have many friends and people I’m close to who are immunocompromised. So for the sake of the people around me, I also don’t want to get sick. When I do events, I wear a mask for those reasons, and because I know that every time I do a talk, while the vast majority of people in the audience have probably moved on, there are going to be other people who haven’t. I think it makes a huge difference to them to have the person at the front of the stage wear a mask. It tells them, It’s not weird. So I do it for that reason, too. In terms of holding this line at a point when a l...

I am sorry if this will upset you. A lot of people depend on NASAL SPRAYS for C0V1D.

I have been iffy on them, but viewed them as "if they don't hurt, why not" but not for me.

There's an analysis
on Reddit that you should read in detail, and make up your own mind.
/1
Here is the link:


Here is a 4 tweet TLDR version.

Here is how it starts - the author goes HARD at the underlying studies. reddit.com/r/ZeroCovidCom…There is no convincing evidence that nasal sprays prevent COVID-19 There is a lot of misinformation out there about nasal sprays preventing COVID-19. Unfortunately, there are no convincing studies showing that nasal sprays prevent COVID-19. The published studies investigating whether or not nasal sprays prevent COVID-19 each have major issues, which I will detail here. I have a PhD in biochemistry and one of my PhD projects was on COVID-19. The main takeaway of this post is that there is no sound evidence that nasal sprays prevent COVID-19. Thus, nasal sprays should not be used for COVID-...
Some pretty harsh language, but to me the important thing is we still have clean air.

Which is good, because it boils down to only 2 studies saying that nasal sprays work, per them. 5. Summary/TLDR and final thoughts Unfortunately, many people including covid influencers have fallen for the grift of nasal sprays preventing COVID-19. Some such influencers have promoted these nasal sprays for free and helped spread the misinformation that they prevent COVID-19. Unlike with nasal sprays, there is ample, sound evidence that high-quality well-fitting respirators, ventilation and air purification prevent COVID-19. The human clinical trials testing whether or not nasal sprays prevent COVID-19 are garbage, and to my knowledge there are only two! Please don't lower your covid...
