What is the science behind Fomite transmission and Covid-19?

Posted: 15 Aug 2021 05:04 AM PDT

My husband is still incredibly concerned of the likelihood of getting Covid via fomite transmission - we still remove all our grocieries from packages and place them in reusable containers, freezer bags, etc. Almost no outside packages are allowed inside the home unless completely sanitized, etc.

I am looking for the science behind fomite transmission and covid-19 - how likely is it to catch covid via fomite transmission, how viable is the virus, etc?

Thank you.

What purpose does inflammation serve in immune response

Have their been any vaccines that were and still are safe for adults but not for children?

Posted: 14 Aug 2021 02:34 PM PDT

With the current wait for the covid vaccines to get approved for children, has there ever been a vaccine that was and still is approved for adults but not for children? Or even where the adult dosage would be dangerous if given to children?

Isolation period of delta variant?

Posted: 15 Aug 2021 02:22 AM PDT

The delta variant produces 1000 times more viral load than the other variations. Would this mean that the suggested isolation period of 10 days be extented? Or if not, why?

How do we know what the inside of the earth looks like?

Posted: 14 Aug 2021 03:43 PM PDT

We never dug deeper than the crust, so how do scientists know the layers of the earth and how big they are?

Do animals that only breed once a year (ducks in spring for example) only ovulate once a year or only get horny once a year?

What fills the space between our internal organs - and do surgeons need to vacuum out the air after opening us up?

Posted: 14 Aug 2021 09:54 AM PDT

In all the pictures I've seen it looks like our guts are packed pretty tightly, organs filling the volume very efficiently. They always look wet, though; what is that stuff? How does it get recycled? And after a surgeon has had to open you up, do they have to try not to close up any bubbles of air in there?

Why certain minerals occur in certain soils and why they don't in certain soil?

Posted: 15 Aug 2021 02:40 AM PDT

For example alluvial soils are rich in potash but poor in phosphorus. Black cotton soils have are rich in iron but lack phosphorus, nitrogen etc.

Is there any detailed material which provides the reason why these soils have such and such mineral?

Are wildfires actually getting worse globally?

Posted: 14 Aug 2021 09:21 AM PDT

It certainly seems that on the news, there have been reports of unusually fierce wildfires in many places in the past couple years, such as Australia last year, Turkey, Greece, Russia and the western United States. I know authorities in California have stated that this year's fire season has been one of the worst on record. President Putin has been on record as saying the wildfires this year in Russia are "unprecedented".

Is there any academic consensus on whether wildfires are actually getting worse statistically? Are these anomalies, or just skewed news reporting? I've seen data that certain indicators, such as the total number of acres burned and number of fires in California, do not show any significant trend since 2000. But I have no idea if these are the correct metrics to use, or how that compares to the situation globally.

If electrons moving through matter makes electricity, what happens when protons move through matter? Can they even move through matter?

How exactly is the delta variant of Covid-19 “more transmissible/contagious” than regular Covid-19?

Can we create artificial antibodies?

Posted: 14 Aug 2021 09:49 AM PDT

Antibodies were described to me as being like enzymes. We've had a lot of luck modifying restriction endonucleases to "cut" DNA and RNA sequences at specific points. Have we been able to engineer recognition sequences to "cut" proteins and not just DNA and RNA?

Disclaimer: I ask a lot of stupid questions.

Edit: 1. I think restriction endonucleases are modified bacterial defense mechanisms acting like their version of antibodies. Restriction enzyme - Wikipedia

  1. What I was referring to is, from what I can tell, when a restriction endonuclease is produced the DNA or RNA codes for a protein to be synthesized. Then, a guide RNA, or maybe DNA sometimes?, then binds to it or combines with it somehow telling the protein to cut it. I was asking if we have been able to create a protein sequence that does the same thing as the part of the guide RNA/DNA that binds to the protein. Then I didn't know if we could add to that piece of protein a conserved sequence of a protein that we want to render useless.

Is the spike protein in COVID-19 the same in all variants?

How do we know that seemingly random things such as the decay of an atom is truely random?

Posted: 14 Aug 2021 06:25 AM PDT

How can we be 100% sure that things like the decay of an atom or quantum randomness is actually random and not just a very complex formula? E.g things such as atmospheric pressure which is used to generate some pseudorandom numbers seems random but isn't, could it not be the same with the decay of an atom?

Does the earth’s surface temperature have an effect on the likelihood of earthquakes?

Posted: 14 Aug 2021 06:57 PM PDT

Like adding a gap in a bridge to accommodate for heat expansion, if the earth continues to warm, will we see an increased likelihood of fissure activity? Or is the temperature rise negligible over something as large as a tectonic plate?

Why exactly does a still scene fade out when our eyes can't do thier saccadic movements?

Posted: 14 Aug 2021 08:22 AM PDT

There's this old trick, you cover one eye and gently use two fingers to hold your other eyeball in place as you look at a stationary scene. Eventually the scene will fade into nothingness.

I know that the reason this happens is because your eyes can't do thier saccadic movements. The image returns if you shake your head for example. Saccades update your vision, make sure the part of the visual scene you're not focusing on isn't changing.

But I don't get how this would lead to the entire scene fading out. Why don't you retain at least a small cone of vision where your retina is pointing?

Can you recieve a vaccine within a tattoo?

Considering there are millions of microscopic, sensitive veins and arteries in my body, does it mean that every time I move, exercise or just by staying alive, small veins continuously burst, heal and create new pathways?

Posted: 14 Aug 2021 10:04 AM PDT

Am I having natural microscopic internal breedings as I'm writing this right now?

Am I having extremely small ministrokes every day and Im not even noticing it because it's normal?

Is there any motor equivalent of visual imagery in conscious thought processes?

Posted: 14 Aug 2021 09:08 AM PDT

When professional dancers consciously remember and mull over a long and elaborate movement sequence they recently performed, are their representations some sort of recollection of (some stage of) the real motor sketch or just the product of propioceptive and perhaps also visual feedback (if they were seeing themselves in a mirror)?

We know from phenomena such as corollary discharge that there is some feedback from motor to sensory processes, otherwise saccades would make it impossible to compute perceptual constancy. But typically this feedback concerns automatic movements and reflexes. What I am interested in is the amodal representations of our voluntary motor plans.

Are these ever conscious? Do they ever have an impact on higher thought processes? If the answer is no, does anyone have an inkling as to why? Simply saying "perception and action are different" sounds dogmatic to me.
