Popular, lengthy article with many embedded links, which I have not followed. https://www.statnews.com/2024/06/04/co2-ventilation-research-virus-airborne-life-haddrell-celebs/ Research Article: Ambient carbon dioxide concentration correlates with SARS-CoV-2 aerostability and infection risk...

This is on my wife's computer, which we bought many months ago but has not been used (much). I am getting this popup. The computer is not running McAfee; it is running BitDefender and Windows Firewall. Task Manager tells me this is Malware nwjs (see background in screenshot). When I ended...

A New York Times article about the current controversy over origin of the COVID-19 virus. Titled: The Government Must Say What It Knows About Covid’s Origins Wide ranging but somewhat superficial, it does have about 15 links to references embedded in it though...

I came across an article on CNN on a bunch of scientists researching the dangers of very old viruses that have been "paused" within the northern permafrost and their prospects of causing infection due to their release which might happen as the permafrost decreases...

forget about chronic fatigue, I remembered it has been tracked to gut bacteria! Epstein-Barr virus seems to be associated with many conditions. "Associated" is the operative there because almost everyone is a host for Epstein-Barr. Science News has a somewhat long but quite readable article...

Hi, I'm getting a warning message that is spoofing my Windows Defender and McCaffee. In my Internet settings, I have blocked popups, yet the message below

I tried a web search but how this immunity stuff works with chicken pox, shingles, and the vaccination I cannot understand. Person can suffer chicken pox infection from the virus, recover, and later be vaccinated (at least age 50) with Shingrix vaccination, to be protected. But the virus is...

Statnews article: https://www.statnews.com/2022/01/13/strong-new-evidence-suggests-virus-triggers-multiple-sclerosis/ Evidence from a colossal blood bank at Walter Reed Army Hospital allowed researchers to look over a long time span of samples for a huge number of US service men/women. The...

Paper, accepted during editing into researchsquare.com, part of nature.com. https://www.researchsquare.com/article/rs-871965/v1 Two species of bats in Laos had Corona viruses very close to the SARS-Cov2-19 virus. Closer than any other virus found. They infect human cells via ACE2, in...

A science team from the university of Kassel (Germany) proved with a physical model, that a moderate electric field inactivates the Convid-19 virus. Source: https://www.nature.com/articles/s41467-021-25478-7 via...

Do virus masks have any effect on preventing or reducing risk of infection from CV19? Have there been any studies on this?

I just found this, but it was published in 2009. A "virus" is described (guessing this is sadly behind a paywall) that is so weird that its not clear it should be classified as a virus. Most of what would be their normal genome has been incorporated into the genome of a parasitic wasp. These...

How can it be that some people develop next to no immunity , cell memory after a Covid infection or vaccination? Immunity develops after the body sees and fights off foreign protein aka virus presenting within the body, so whichever has gotten infected with the virus has to undergo these steps...

I firmly believe China should give financial reparations to the world for creating and spreading Corona virus.

I'll trade a cold for Covid-19 any time! https://www.medicalnewstoday.com/articles/a-common-cold-virus-may-help-fight-covid-19 Cheers, Tom

Paul Biensiasz is a virologist at Rockefeller Medical, he authored this on twitter, titled "musings of a pissed virologist"

Homework Statement:: Does Sars-cov-2 Virus have Reverse Transcriptase enzyme for its replication purpose? Relevant Equations:: None I surfed Google for a relevant answer to my query but failed to find one.I just want to confirm whether Sars-cov-2 has the Reverse Transcriptase or...

The sudden appearance of SARS-COV-2 as a virulent pathogen in humans raises the question of how it gained the ability to attack human cells and why it is highly contagious. If I understand this right, an article in Virology Blog...

Corona has come and it doesn't seem to go away that easily. Why can't modern science find some cure that will prevent so many deaths? Why for example we can't find an antibiotic for this specific virus? What about other approaches(vaccine)? I just wish a cure could be found so we may continue...

Could this year's flu season be used to determine the effectiveness of virus masks? Every other person if wearing one, so if flu cases are significantly less than normal, that means that virus masks are having a noticeable effect?

Here is a Carl Zimmer article in the NY Times showing some fantastic images of the corona virus. These are mostly computer generated images (pretty common these days) based on cryo-EM (Electron Microscopy) and biochemical/molecular biology type data. They are very well rendered, down to the...

Hi All Someone passed onto me the following supercomputer analysis of the Covid virus: https://elemental.medium.com/a-supercomputer-analyzed-covid-19-and-an-interesting-new-theory-has-emerged-31cb8eba9d63 Very interesting. Thanks Bill

This has come up in the press the last few days that they now believe Covid-19 is not just a respiratory disease. This is a very interesting article on it. It explains the virus and how it works. https://www.ucsf.edu/magazine/covid-body

I bought a can of soft drink and was wondering whether I should spray 100% isopropyl on it before putting my mouth on it to drink. I did spray and it smelt bad but I wiped it off and drank the can. Is that unsafe or is it the opposite, safer than drinking without spraying? Would it kill corona...

In any viral infection, we know that an invading virus enters the cell and damages them (cytolytic/cytopathic). This may be a starting point for inflammation down the road. Though initial inflammation may be beneficial, a longer than necessary inflammatory process proves more damaging than...

I've been thinking about this but now especially with regards to Covid-19 there are a lot of theories out there starting from absolute fringe and lunacy to somewhat scientific and even ones with sources to academia. For starters not to get too long my question is, What is our current known...

I once read that just because a virus mutates doesn't mean you lose immunity to it. I do not know much biology, but could one of you please explain how that is possible?

What is the probability that a healthy person with fully functional immunity will become infected when he receives a tiny amount of some (flu kind) virus on a) hands, b) eyes, c) lungs? I don't know how to define a small dose of a virus, but I guess if only one virus gets in my lungs, my immune...

Covid-19 affects mainly the elderly so the results are partial lockdown and many youth still swimming at Miami Beach. And the elderly victims are drowning at ICUs even with ventilators. In Contagion. The virus affectedthe brain instead of the lungs and the result was encephalitis (infection of...

Viruses when they infect us, enter the target cells, hijack the machinery and start producing their own Copy and eject out. So what? Question is, how do they directly cause injury to our cells? Do they harm injury our cells directly? Of course we know that our own immune system which becomes...

I keep wondering why we do not know more about the virus? How hard is it to expose some mice to Coronavirus and see what happens? Then I considered that perhaps the virus is primarily a human virus and does not effect other life forms like lab mice. There have been cases with dogs and the...

1. are there H2O molecules inside a Corona vírus? If yes, drying the virus kills it? 2. the lipid external layer of the Corona virus acts as a glue that attach the virus to any surface? 3. how much time a Corona vírus survives in the dry air? and in a dry surface?

If oxygen is effective against bacteria virus and cancer why isn't it used against coved-19? DMSO is known to bond with certain substances and could carry HP into the blood stream and kill off COVID-19.

The summary says it all. But to give an example, imagine a mild virus that has gone the rounds of Region A. Later it makes its way to Region B, and immediately mutates into a more rapidly spreading strain that puts B's inhabitants at great risk. Now that new strain travels back to Region A...

I have a question both with regards to the current virus as well as to other potential diseases that are carried around in aerosol form, I have seen that commonly all hand sanitizers or sanitizers in general that use substances that are safe to humans use alcohol in some form. So I would presume...

I was trying to put together a basic mathematical model for the Coronavirus and happened to stumble across the predator prey model; if ##x## is the number of humans and ##y## is the number of Covid-19 viruses, then $$\frac{dx}{dt} = ax-bxy$$ and $$\frac{dy}{dt} = cxy - dy$$ I took the reciprocal...

Name Yaravirus found in an artificial lake with 90% novel genes. Evolution significance?

Science believes that a virus does not have life. They do not display any of the properties of 'life' such as homeostasis - they lack, growth - they don't grow, response to stimuli - they don't respond etc. i.e., They're not as alive as bacteria, animals, humans. If so, how come they want to...

I installed mapsnow.co on my computer, is that a virus or just an apt?

This Science News article reports that researchers using a modified adenovirus (that normally causes mild respiratory infections) that only grows in retinoblastoma tumor cells, researchers were able to improve upon (but apparently not cure) the results of cancer drugs in rabbits and mice. Trials...

Hi. Double slit experiments are being performed successfully with increasingly large molecules. Some physicists (e.g. Anton Zeilinger) believe it might work with viruses as well. Assuming it works with a system that qualifies as a measurement device (be it a virus or something else complex...

I noticed this widespread adware infecting chrome on nearly all devices. For a few days though i have noticed that on all the devices when the spam sites are opened by that virus they close immediately. Is it that chrome got to know about it and has defeated it? But why is the virus still...

I just want to let you know what I suspect I got the virus from. I don't serve on questionable sites, no porn sites or anything close to like that. I read articles on Yahoo front page. Lately ( last year), they start to have articles like "How's you favorite tv stars from the 80s look like now"...

Can virus infect memory stick? I backed up my files onto the memory stick from my infected laptop. Can virus get copied into the memory stick? Can virus infect pdf, jpg, doxx or other files? How can I scan the memory stick without worry about infecting another computer that try to scan the...

This new virus used multiple means of attack to infect machines on a network. The initial attack came from a legitimate software updater program: http://www.zdnet.com/article/microsoft-petya-ransomware-attacks-were-spread-by-hacked-software-updater/
