How did the Australian coronavirus vaccine produce HIV antibodies?

Posted: 11 Dec 2020 04:01 AM PST

The Australian vaccine effort has been halted after it produced HIV antibodies, leading to a false positive for HIV. Why did a coronavirus vaccine do this?

Was the 1918 pandemic virus more deadly than Corona? Or do we just have better technology now to keep people alive who would have died back then?

Posted: 10 Dec 2020 09:01 AM PST

I heard the Spanish Flu affected people who were healthy harder that those with weaker immune systems because it triggered an higher autoimmune response.

If we had the ventilators we do today, would the deaths have been comparable? Or is it impossible to say?

Will plasma from vaccine recipients be as effective of a therapeutic as plasma from those previously-infected?

Posted: 11 Dec 2020 03:20 AM PST

I've heard (anecdotally) that giving critical patients plasma from someone who has recovered from COVID-19 seems to be a very helpful treatment. Presumably, this plasma is in short supply. Should vaccine-recipients be similarly encouraged to donate plasma? Would the plasma from the vaccinated be as effective or more effective of a treatment?

How does sleep deprivation cause hallucinations/paranoia/etc.?

What part of the brain does it affect? How does sleep do anything? How does it work?

Does Alzheimer's merely hinder access to memories through destroyed pathways, or does it destroy stored memories, or is it a mix of both?

Does water cool down and warm up at the same rate?

Posted: 11 Dec 2020 04:06 AM PST

Example of what I mean: say the ambient room temperature is 25C, I have a two glasses of water, one at 20C and the other 30C. Will the two glasses reach 25C at the same time?

How exactly is limestone (calcium carbonate specifically) formed?

Posted: 10 Dec 2020 10:20 PM PST

Is calcium carbonate only formed biotically like in the case of coral and seashell creatures, or is there a way to form it abiotically? How is there so much limestone inland? Was that formed abiotically or was it left there by ancient oceans or uplifting or something?

If rocks and fossils are millions of years old, how come whenever there is a comet crater there isn't anything there anymore?

Posted: 10 Dec 2020 08:51 AM PST

Excuse the non-scientific explanation. I have always wondered why comets aren't still in the ground and there is only a crater there. Does the comet rock matter get broken down quicker in earth's atmosphere? And the minerals in rock produced in the earth's core out live the comet? I'm baffled

Are we able to isolate, store and accumulate neutrons?

Posted: 10 Dec 2020 10:35 PM PST

Few questions come to mind: what vessel/container could even hold a subatomic particle? And I assume neutrons are stable and inert, but, outside of an atom, are they?

What really drove me to ask this is, what's a pile of (free) neutrons like?

String can never be fully horizontally in centripetal motion?

Posted: 10 Dec 2020 08:54 PM PST

I did a lab in my AP physics class where we spun a rubber stopper on a string in a horizontal circle. However, I was wondering how the fact that the string pulling the stopper isn't fully horizontal creates errors in the experiment. I know the tension force has an upward component to counteract gravity does this affect the radius? What errors does the string not being perfectly horizontal cause? Thanks in advance!

Why don't magnetic fields expelled by solar flares behave like light?

Posted: 10 Dec 2020 03:44 PM PST

I was just reading this news article about how the Northern Lights might be visible in Oregon tonight because of a solar storm: https://www.cnn.com/2020/12/09/us/northern-lights-display-wednesday-night-scn/index.html

The article states that a solar flare already happened on 12/7. Why aren't the magnetic fields created by the solar flare here already--i.e. why didn't they travel at the speed of light? Isn't it all EM radiation?

Will virus-transmission increase exponentially or just marginally when people are simultaneously co-infected with two infectious diseases?

Posted: 10 Dec 2020 06:53 PM PST

Currently we are in the midst of influenza season as well as a global pandemic.

I understand that it is possible that a person can be infected by both COVID and the influenza strain at the same time. That brings us to my question about co-infections.

Covid and the flu, share a lot of the same symptoms that spread infections, with the flu having runny noses as a symptom too. How would this affect transmission ratse when the populace is infected with both the flu and covid?

Would the R0 factor raise dramatically or only marginally? Especially if we take in account that both diseases are mutually spreading each other.

Can a self-replicating vaccine run wild in the body?

Posted: 10 Dec 2020 07:46 AM PST

After I heard some vaccines are self-replicating, the question hit me. What keeps the mRNA from entering every single cell in the body? Is that even a problem if it does? It only changes the outer shell of the cell?

I have no clue about biology other than what's taught in high school.

What is the average number of deaths per day (all causes) in the US and is it clear the pandemic has increased the average deaths per day?

Posted: 10 Dec 2020 06:17 PM PST

First I must be clear I am not a denier of the pandemic. It seams that those that believe COVID deaths are fake may be swayed by a chart showing a substantial increase in overall deaths per day over previous years. I have been unable to locate such a magical chart. Thoughts? If this is not the right place to ask this question I would love to get a recommendation for another sub.

Why does Genetic Anemia effect Asian and African families more?

Posted: 10 Dec 2020 04:35 PM PST

Why are genetic anemia conditions more common in Asian and African families?

Thalassemia runs in my family and the internet says that it is most common in Chinese people.

Why does race have an effect on this?

How significant is age-related (not including disease related, e.g. Alzheimer's) cognitive decline and at which ages?

Posted: 10 Dec 2020 03:35 PM PST

The combination of current age-related political discussion and watching my own parents' mental progress over the last 15 years or so has me thinking about the statistics of age-related cognitive decline. Obviously there is likely to be a distribution among populations, but I think we can all agree it's unusual for someone in their 80s or 90s to have the same mental acuity they had in their 40s.

How much science is there behind this?

What is the fate of hypoblast?

Posted: 10 Dec 2020 11:32 AM PST

I am a little confused about the formation of endoderm and the fate of hypoblast. I understand that epiblast cells migrate through primitive streak to form mesoderm/notochord. I also understand that ectoderm arises from epiblast.

Do mesoderm cells replace hypoblast cells and form endoderm or do hypoblast cells just differentiate into endoderm?

Also an additional question is, do the hypoblast cells line the whole yolk sack? If yes, does hypoblast line the yolk sac even after formation of the endoderm, mesoderm and ectoderm?

Are things in our peripheral vision distorted?

Posted: 10 Dec 2020 03:05 PM PST

I was wondering if there was any impact on our vision due to the curvature of our eyes, similar to how a map is distorted due to the projection of a 3D image on a 2D surface. Am I thinking this out correctly or does the curvature of our eyes contribute to us being able to see in three dimensions?
