“The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.”
― Isaac Asimov
"There is a cult of ignorance in the United States, and there always has been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that 'my ignorance is just as good as your knowledge.'"
- also Isaac Asimov
the internet has given knowledge to people who can't put it all together correctly and as a result you get some interesting yet incorrect and dangerous deas about the world, i just hope this knowledge in people becomes more refined over the next decade or its gonna be looney town for a while

I guess it goes without saying, but "More research needed." Is there a t-shirt? I might buy one of those if there is. And if there isn't, there needs to be! 😊
Yep there's the usual hedging by experts designed for the benefit of the dumbest among us for liability protection but they have gone well beyond that during this pandemic. Too many are trying to influence people's thoughts as well as actions by constantly saying we won't know anything for quite some time. They know plenty about this virus and the things discussed among the experts and elites behind closed doors and the personal protocols they employ are going to be different than the sanitized, processed and limited information given to the public as well as access to certain treatments and preventative measures. I'm glad professor Gruber of MIT got caught explaining their methods as well as their beliefs about the American public during the ACA scandal.

"you require additional research"
Hm. Haven’t found it yet but the shirt might be out there, somewhere. More research needed.
All those grants and people claim there is no incentive in "green" research .... 97% of dentist agree dentistry is an important field too.
Hank is absolutely right that T cell immunity only refers to T cells activating and exerting an immune response to the coronavirus. This doesn’t necessarily imply that people are immune to it though. If that was the case, authors of these studies would use the term “T cell-mediated protection” or something to that effect. A vaccine will need to elicit a protective immune response for it to be effective. It’s useful to know that T cells react to coronavirus, even in people who haven’t been exposed to it, but until we have clinical data we won’t know if this response is protective or not.
Shorter, simpler version: We're seeing that there might be a common T cell response to Covid-19. What we don't know is whether or not it's an EFFECTIVE response. Not all of them are.
@@Seaton1518 who is correct, a vast sea of educated voices rigourously studying and trying to keep people alive, or you, an intellectual, who doesn't seem to understand that not everyone becomes seriously ill or even symptomatic, but that those people can simply breathe around the wrong person and kill them, their family members, and hospital staff?

“A lie can travel halfway around the world while the truth is putting on its shoes.”
― Mark Twain
Not quite true, imo. "Something interesting can travel halfway around the world while something boring is putting on its shoes."
There can be truth that is really interesting that will spread fast. Unfortunately you might get 'Chinese Whispers' with what's being spread, such that it becomes a lie, but I think it's interesting information is what spreads fast - regardless of whether it's truth or fiction.
Which sounds horribly optimistic to 21st century readers. Until one considers that Samuel Clemens lived before Twitter, before the Internet, before widespread radio, before widespread telephone, before widespread audio recording, before movies...
Though, the quote appears to have originated elsewhere and elsewhen than from Mark Twain.
Edit: Though I haven't found the specifics, the most agreed upon (that I've seen) origin of the quote is from Jonathan Swift (1667-1745).

Any study on if less people have gotten the flu this year, due to people wearing mask?
That's a good question. I'm wondering about that myself since a friend's 20 year old daughter was just diagnosed with flu, not Covid 19.
*if fewer people*
@@tessat338 in germany we had abnormal high cases of rhino viruses in summer, while we have to wear a mask.
What do you think about it?
In the U.K. there are apparently less cases of flu. The real impact of masks and handwashing will become clear during the winter flu season.
I work in disability and my client hasn't had the flu once this year. Usually she's contracted it 3 or 4 cold & flu by this time of year..
Staying indoors has helped her too. It's been a good health year for her..

As always great explanation scishow! Well done on cutting through the antithink.
I've been reading a lot about the new "bradykinin storm" theory in relation to COVID and would love to see a video on that!
Completely agree. Highly underrated comment.
Yes, I read an article on that about a week ago. While it didn't give any conclusions it did posit a few interesting hypotheses. It also may explain a few things that have stumped scientists.
Cytokine is a group of enzymes responsible for inflammation including Histamine, Bradykinine...
@@duyson5632 Bradykinin storm leads to blood vessel dilation and leakiness, allowing fluid to drain into the lungs (or other compartments), and it can screw up the electrolyte balance too, leading to changing mineral levels, and some minerals can cause more heart or other organ complications if they get too low. A cytokine storm is when the immune system goes nuts and produces too many immune cells, which can start attacking healthy body tissue all over the body.
The effects are distinctly different, and both can occur at the same time for some really unfortunate people.

This is the best news I've heard
I just want to say thank you for everything you folks do. You do it intelligently, humorously, and keep the politics out of it.
Very interesting. This disease is so confounding in its’ ability to be so many different things at the same time.
I checked in to see about the r value reported in the UK of 1 to 1.2, that's r for reinfection, right? Can you explain what that means?
The R value or R number is the reproductive number at any point in time. Once herd immunity is achieved the R number should drop to almost zero. An R number of 2 means each new infection goes on to infect two more people that are not yet immune or protected. The UK R number of 1 to 1.2 must be for at this point in time, taking into account social distancing, masks, etc.
The initial reproductive number or “R naught” (R0) is more interesting. This is the R number when the virus encounters a virgin population with no prior immunity and they are not yet taking any precautions. It is a worst case and it can only go down from here. It tells us how fast the initial spread can be. Accurate R0 numbers are difficult to ascertain.
*R0 (initial reproductive number) of some pandemics and major diseases*
• 1918 Spanish Flu (H1N1) R0=2.4 to 5.4 (or between 1.4 and 2.8 by some estimates)
• 1957-58 Asian Flu (H2N2) R0=1.8 (or 1.08-1.11)
• 1969-69 Hong Kong Flu (H3N2) R0=1.06-2.06 for the first wave and 1.21-3.58 for the second wave
• 1983-to-now AIDS untreated (HIV) R0=3.4
• 2002-03 SARS (SARS-CoV-1) R0=0.19-1.08 (or between 2 to 5 by some estimates)
• 2009 Swine Flu (H1N1-09, likely the same variant as 1918) R0=1.47 (between 1.4 and 1.6)
• 2013 Avian Flu (H7N9) R0=0.03 to 0.4
• 2013-16 Ebola Virus Disease (Ebola) R0=1.3 to 1.8
• 2014 MERS (MERS-CoV) R0=0.45 to 3.9
• 2020 COVID-19 (SARS-CoV-2) R0=2 to 3 (possibly as high as 5.7)
• Seasonal Flu (influenza A and B, e.g. H1N1, H2N2, H3N2, H5N1 variants) averages about 1.2 now but has an R0 of 2 to 3 depending on the specific virus variant
• Common Cold (multiple viruses, especially rhinoviruses but includes some coronaviruses) R0 is around 6
• For comparison, the R0 of Measles is 12 to 18, Malaria is 16, Chicken Pox is 8.4, Small Pox is 6, Dengue Fever is 5, Cholera is 2 and Bubonic Plague is 1.

In some of the plasma treatments the concentration of antibodies is not high enough. A crucial step is being skipped. It work better if you allow the antibodies to grow and multiply in an incubator before administering them.
That’s strange that this is the question as I was watching a video on the Brain Virus a few days ago
Researchers at the Oak Ridge National Laboratory in Oak Ridge, TN, cracked COVID-19. It actually binds to ACE2 receptors sparking a bradykinin storm and this is what causes the sometimes bewildering symptoms, most of which are also side-effects of ACE inhibitors.
Can life exist in a state of matter other than solid like living plasma or living liquid
Hi!
I have a question, do we know if people that had covid 19 and recovered are completely immuned? Or is there a chance of being re-infected sometime afterwards?
I've been meaning to ask this one for awhile, but I keep on forgetting. If I wanted to volunteer for a vaccine trial, how can I sign up, what can I expect, and how do I know if I would be a good volunteer?
@Scientific Humanist hopefully not life, I just want to do my part to help end this.
@Scientific Humanist He will not die
I've been chilling at home, let me know where I can donate some T cells. Lol
MrGrombie That wouldn’t be useful to anyone tho cuz of graft-vs-host reactions
@@waterunderthebridge7950 Think he's referring to exposing cells in testing to see what happens.....
Corwin Weber Even then, as said in the video, it is very difficult (in some cases even impossible) to induce reaction of the immune system with just in vitro data of a single cell group. You’d need to volunteer your person for testing (there are multiple groups internationally who volunteer for vaccine testing with direct pathogen exposition)
A “safe” option by just donating cells would 1) take very long to establish (as you’d need immortalised cell lines for extended research), 2) be very hard to derive general data applicable to the entire system from and 3) thus not very productive
Nevertheless, there may be novel approaches dealing with this experimental setting

if you could do a similar analysis on the medicine used for MS, specifically Tysabri,
I would like to know what it does in all actuality, and how it affects the immune system, and maybe what it's made of
I have tried asking at the hospital(s), but I have never gotten a real answer, and I think that I would understand it if you explained it 😅
I actually have a question on a kind of related theme, the over/under reaction of our immune system. People on immunosuppressant medications were on the verge of dropping their treatments because of COVID-19, but then some of those folks really got the virus and, surprisingly enough, they got somewhat less damage from known immune havoc like pneumonia than people with not regulated immune systems. No mentions about other problems that are suspected to emerge from COVID-19, though. That information was from a conversation with a neurologist, it would be great if you could find some more info for us. Cheers!
This makes sense. Most of the damage and danger comes from the body’s immune system overreacting to the virus while the virus can actually quietly coexist with us if we let it (e.g. asymptomatic people).
There’s a wide range of problems with our immune systems for all sorts of things. Some years ago, I had a nasty problem when a chunk of bone which had been temporarily removed, then reinstated, turned out to be infected by a bacterium (staph aureus in this case). On account of it being physically disconnected from my main blood stream, the bacteria was warmed up to normal temp and inaccessible, so my main system was completely screwed up, wouldn’t do normal blood clots for other minor injuries etc.
In the longer term, the infected bone, and a bit more, were removed again (and destroyed ), and followed by an aggressive antibiotic (intravenous, 2g every 6 hours for 14 days), then when things had settled down it was replaced by an artificial plastic structure, manufactured specially in line with older x-ray images, in effect.
So does the word immunity in general mean response and not protection? Or is it just in this context?
In late Feb 2020, my husband was on a plane, had a guys weekend, some got sick or had symptoms, before we knew about coronavirus. I was not home for the five days after he came home. After the news broke, we joked, for maybe he had built anitbodies. BUT He was diagnosed with a fast-growing rare T Cell lymphoma by July (over by his left armpit). So Im wondering about the opposite cross-reactivity instead of what is out there and talked about - rather, could the virus and it's tcell relationship cause a tcell reaction and result in ALCL? My husband up to this point was a Hodgkin's Lymphoma survivor from 15 years ago. This time it was completely baffling - no symptoms. Looking to contact researchers to see if they've thought of this angle and to see if there's been research in this or any rise in Tcell lymphomas since covid-19.
Thanks for any help,
Kind regards.

@G O So much misinformation from one person. Incredible.
@matthew styles The summer has already passed and we still have a virus. It won't just "go away" until herd immunity is achieved. And ahhh yes, a infinitesimally small amount of discomfort is far to much to ask to protect other's lives.
@G O
Stay 6 ft apart or spend less than 15 minutes near a stranger and you won't get sick. No need for a mask if you do this. So far very few people have gotten sick because they are doing exactly this.

Having heard the sentence, "Immune people can be aa high as 20-50%", I am now afraid that some people might have paused the video and said that they are already immune.
If the video means always asymptomatic, the current thinking is 16% nationally. If pre-symptomatic people are included in this percentage, well, all infected people are this for a couple days or more so I’m not sure how to count them. It would depend on whether an outbreak was active at the time of counting. In some institutions like prisons, the asymptomatic group has been found to be 95% of the infected population. It might be that another seasonal coronavirus made its way through the prison population somewhat earlier conferring partial immunity against COVID-19.
@@cloudpoint0 you are mixing up "immune" and "asymptomatic". It is a common mistake, but these are different things. And the difference is important when we want to talk about an infectious disease.
"Immune" means you do not get infected. The virus is defeated immediately before it can set up shop in your cells.
"Asymptomatic" means you do get infected, but experience no symptoms. But the virus has infected your cells and is replicating.
@@eljanrimsa5843
You are the one who is mixed up.
"Immune" means you may or may not get infected but you are able to stay healthy. More likely you will get infected, or do you think the virus will sense that you are immune and just bypass you?
"Asymptomatic" means you do get infected, but experience no or few symptoms. You got that part right. But the virus likely is not replicating or not replicating very much or you would be symptomatic. Do you think your lungs can just indefinitely fill with puss and not show any symptoms of being sick?
There is nothing I would change about my earlier reply even if you had been correct. You don’t appear to have digested my point correctly. I did not mention immune and asymptomatic in a context where you could say I was confused. I did not say one where I might have meant the other. Please read more carefully before you start telling someone who has taken a 26-week university-level virology course that he doesn’t understand virus terminology.
@@cloudpoint0 IIRC there have been studies showing that people infected with COVID-19 but who are asymptomatic are just as likely to infect others as those who are symptomatic. Based on that, your claim that the virus is not replicating or the person would be showing symptoms seems inaccurate.
Of course, I haven't taken a 26-week university-level virology course... 🙄
@@lyreparadox
What you say is not true now although earlier studies thought this was the case. Knowledge grows. I think it is actually rather logical that a person who is not sneezing, coughing, etc. will shed very few virus droplets, or maybe even no virus droplets if their infection is not in their respiratory tract or it is deep inside their lungs where little or no air is being exchanged.
The proportion of people that remain asymptomatic after infection is now thought to be 16% (down from about 40%) and about 27% among children. This is true at least in large UK studies per Dr. John Campbell at the link below. This percentage can vary greatly among smaller populations. 95% was reported in one American prison system. Researchers might have been seeing transmissions from pre-symptomatic people in the first studies without discerning them from asymptomatic people. Pre-symptomatic people can definitely transmit the virus during the last couple days of their six-day incubation period and for a week or so beyond (typically).
ruclips.net/video/dbtPshdK1Kw/видео.html
“Asymptomatic transmission refers to transmission of the virus from a person, who does not develop symptoms [ever]. There are few reports of laboratory-confirmed cases who are truly asymptomatic, and to date, there has been no documented asymptomatic transmission. This does not exclude the possibility that it may occur. Asymptomatic cases have been reported as part of contact tracing efforts in some countries. WHO regularly monitors all emerging evidence about this critical topic and will provide an update as more information becomes available.” - The WHO back in April
www.who.int/docs/default-source/coronaviruse/situation-reports/20200402-sitrep-73-Covid-19.pdf
The viral load is very important in terms of whether you can infect someone. The RT PCR test picks up viral loads starting from 100 pieces of RNA debris. That’s when the test says you are positive. At 5000 pieces you are still not infectious. Even at 50,000 pieces you are still not infectious. In theory you might be slightly infectious at 1,000,000 pieces of RNA but this is not likely. You don’t really become infectious, at least in a way that’s a risk to others, until you measure 3,000,000 pieces of RNA in a nasal or throat swap. You still aren’t guaranteed to pass on the SARS-CoV-2 virus even at this high level. [It's hard to count actual viruses so they count something easier instead.] There’s a big difference between being infected and being infectious. Asymptomatic people likely don’t meet the infectious threshold although they are definitely infected. Or at least they are less infectious. The CDC seems to agree with this view now.
*CDC quietly revises coronavirus guidance to downplay importance of testing for asymptomatic people*
The CDC is now calling *asymptomatic* infected individuals “healthy people”. The updated guidance also removed a line on the importance of testing and surveillance to the U.S. national response plan. Testing isn’t all that important, it now seems. They are discouraging general testing and asking to focus testing on certain groups. By this update they are implicitly acknowledging that asymptomatic individuals are not a major cause of the virus spreading. This is more-or-less what the WHO have always said.
“The updated Guidance places an emphasis on testing individuals with symptomatic illness, those with a significant exposure or for vulnerable populations, including residents and staff in nursing homes or long term care facilities, critical infrastructure workers, healthcare workers and first responders, and those individuals (who may be asymptomatic) when prioritized by public health officials.” - The CDC

"Creeper System" and I live in da UK! xD
I was hoping that this addressed the question of whether people infected with Covid 19 develop immunity to sars-cov-2 to further infections, and what that immunity looks like- true immunity or just milder symptoms. I'd love to hear about the current research on that!
I believe it is true immunity although how long it lasts is still up for debate.
If someone got the super power to warp space, if they lets say walked across a street. as an observer would the environment look squishy like a collapsed accordion & the guy look normal crossing the street or would the street look normal & the guy look stretchy like mr. fantastic as he crosses the street?

I've had a positive PCR test on COVID 19 three weeks ago. Fast forward 21 days later, with ZERO symptoms through out, my test for igg antitibodies returns negative. Having had a rather exhausting flu-like illness back in january makes me think that back then it was a virus similar to COVID 19 and that my T-cells actually fought off the virus this time. Any thoughts?
I would like to see more information about re-infection. Specially, after being vaccinated, how long before re-vaccination. Is it like the seasonal flu? Or one time vaccination is enough? Re-infection means the virus has mutations, how often does this virus mutate? I think there are lots of young people who think they can't get covid because they already had it once.
What you gou got on ig M igG values and inmunity?
I wonder how long T cells are viable for testing in stored blood and serum or plasma. Because in the trial I'm a part of at least, they took a few vials of blood before I was given a shot. So they could do the test retroactively potentially - and there's thousands of us.
Has anyone figured out just what happens in the pupae to change from larval stage to adult? This would seem to me to be worth pursuing due to the fact that ALL of the organs are broken down and regrown for a different purpose. This could be useful for human cell repair.

So my question is, would efforts made earlier this year to flatten the (Covid-19) curve imply that the influenza curve has also been flattening, and impact the supposed fall flu season at all?
In most US states, the daily case counts began to decline when official case numbers hit 1.5% of the state population. If not due to a combination of some immunity (natural or acquired) and mask/distancing measures, why? Why do daily case counts continue to drop?
I'm very curious to see you cover people who are HIV+ but undetectable and their stats with covid-19. Early on I heard that there seemed to be fewer of that demographic showing up with the disease than expected. It was all speculation, but some professionals infered they we're receiving some protection from their antiviral cocktail.
A few months ago, when cases spiked around the world, we read in science, or some other for public consumption science rag that SARSCOV2 was mutating by a few proteins. Could that have contributed to the sharp rise in cases? Has it really mutated, and if so, what about it has?
I would like to ask if a person who has taken yellow fever vaccine which is actually concentrating on T Cell and not antibody so how it is affect against Covid 19 virus?
Yeah, science!!!
So basically what your saying is that my T-cells are LIKE the captains and generals in my immunity Army? That’s cool.
Oh, past Hank was so optimistic *sighs in 2021*
I find it sad that a lot of this information that you guys always pop-up comes to light when it's information that has been there for a long time but people aren't sharing that information quick enough so their information seems like it's new but it's been there for a while sad still keep up the good work sicshow
Question for a future episode: What would happen if a 1-foot amplitude gravitational wave were to hit Earth?
A paste in head when you feel something high temperatures. Colgate. Ayrbed with neem leaf memory t cells
I'm glad there is a good source of reputable data. I only wish more people cared to understand it.
This video was posted very late here in the UK
I had COVID-19 last month and the symptoms were super-mild, I was super-tired for 3-5 days and my taste buds tripped out, everything tasted wrong and certain foods tasted like my mouth had been burned. Otherwise no symptoms and I got tested so I know I had the virus.
JSeaton that’s exactly what I was thinking the whole 3 weeks I was “quarantining” in my grandpas garage apartment. Just 3 weeks of playing guitar and watching RUclips... ‘twas a nice vacation but yeah, it seemed like it was hardly dangerous at all, but at the same time I know a few people who had to be hospitalized so maybe we have this T-cell immunity and the virus just got manhandled when it entered our systems, where others weren’t so lucky.
Not everyone has mild symptoms, you know. People die from this, even healthy and young people sometimes. And many of those who do will suffer lifelong complications. Saying the virus isn’t dangerous just because you had a mild symptoms is like saying “I got in a car crash, survived and only got a few bruises to boot, so car crashes ain’t dangerous.”
@@Seaton1518 How is it a hoax? Did anyone say that YOU would die? No. Symtoms you describe are exactly what you've been told. Loosing smell and taste means your brain has been affected so it's nothing to shrug at.
@@vileguile4 the loss of taste and smell is due to sinus pressure. From my personal experiences, I loose smell and taste every single time I've had cold/flu.
@@ianhennessy3161 Sinus pressure would mean that you at least notice it, right? At least i feel pretty bad when it's gone that far. With covid many who looses their taste/smell have no other symtoms so only sinus pressure would not be enough. Maybe im wrong but i don't think i am.
Was the first virus Stuxnet? Or was Stuxnet later?
Yes, I have a question: how does the IFR of covid relate to other comparable viruses or flu like viruses and how does the IFR relate to our lifestyles?
Getting to 6.9 million subs
When will the COVID-19 pandemic peak in India? After all we have been facing it since February.
Look at European countries (italy, uk, spain) death per million at their peak then routhly translate that over to India, could be around that mark
We're already peaking
So... Getting closer to T virus... Capcomverse will include megaman as well please?
So why or how did this virus come about?
I'd probably nail the Techie Test but I'm in the US ;-;
Sorry I already watched Cells at Work!
new anesthesiologist came to the hospital im rotating at because he worked on the breast cancer t cell vaccine and hes working a covid19 t cell vaccine as well. claims it lasts 13 years vs the antibodies only lasting 50-60 days.
I wonder, if a friend or relative had the covid-19 and have recovered, and I see them not long after they're better - ie while they're still spreading parts of dead viruses - and if I get in contact would that trigger immune reaction? After all one type of vaccine is with fragments of dead viruses or even artificial receptors (against which we want the immune system to react)
