What percentage of genes are purely human?

Posted: 27 Feb 2021 04:58 PM PST

We share ≈96% of our genes with gorillas, ≈50% with bananas, so if we added all the specific shared genes what percentage is purely human?

What is the Yukawa potential calculating?

Posted: 28 Feb 2021 01:08 AM PST

The Yukawa potential seems to predict the strong interaction, the weak interaction AND the electromagnetic force. But that seems "overpowered"...

Have long-haulers or people suffering from chronic symptoms related to SARS-CoV-2 infection shown benefit from any vaccine?

If a nursing mom receives the COVID vaccine, will protective antibodies be transferred to the baby via breastmilk, essentially helping to “immunize” the baby who can’t yet receive the vaccine?

Is it possible to be exposed to COVID and develop antibodies (enough to have short term immunity) without ever having a high enough viral load to test positive?

Why do real vaccines hurt more than placebo vaccines?

Posted: 27 Feb 2021 10:34 AM PST

The tl;dr is the title.

I'm in the J&J 2-shot COVID vaccine clinical trial. (It's double blinded, so I don't know whether I got the real vaccine or a control placebo.) I just got my second shot today. One of the things the nurses said, both times I got a shot, is that if my arm was sore right after the shot, it's more likely that it's the real vaccine.

It could be psychosomatic, of course, but I'm still curious, why does the shot hurt more when it's real? Is it just because the body's immune response is that fast? I figured the pain was a normal response to the skin being pierced and to having a shot, but if that's the case then both the real deal and the control would hurt the same amount. What in the real vaccine — either the way it's administered, or its contents — makes it more painful to receive?

How is the J&J COVID vaccine is manufactured is the "pseudo-virus" cannot reproduce, and what safeguards are in place against unwanted mutations?

Posted: 27 Feb 2021 10:20 AM PST

I'll start by saying I'm not anti-vaxxer and I'm looking forward to my turn to be immunized.

My understanding of how the J&J vaccine works is as follows - it's a "pseudo-virus" that infects our cells and instructs their membrane to produce spikes mimicking the COVID ones, thus teaching our immune system to recognize the virus. I also understand that it's safe, because this pseudo-virus cannot replicate. Now to my questions:

  1. If the pseudo-virus cannot reproduce, how is the vaccine manufactured?
  2. What safeguards are in place to prevent mutations that would allow replication?

What does IQ measure, and how accurate is it st measuring that thing?

Posted: 27 Feb 2021 01:23 AM PST

This seems to be something where people can't give a straight answer and nobody seems to agree. Some people seem to say it is a great measure of intelligence and good at predicting performace in intellectually demanding tasks, others say it is absolute bunk and doesn't measure anything useful. Both groups seem to claim the science is on their side. They can't both be right. Do what actually is the deal?

What is the real efficacy of the Johnson & Johnson vaccine? Are there upper and lower bounds on it?

Posted: 27 Feb 2021 10:17 AM PST

The news articles I have read go to great lengths to say that you can't compare it to Moderna and Pfizer's vaccines due to the different ways they measured efficacy. I get that they don't want people to refuse one vaccine in favor of another, but I would like a science-based explanation, rather than what a journalist's second-hand interpretation.

Why does atopy inversely correlate with severe covid outcome?

Posted: 26 Feb 2021 08:22 PM PST

Can someone explain why atopic conditions like eczema, food allergy, and allergic rhinitis correlate with milder Covid consequences? I am not a medical professional, so I don't understand how atopy would be protective. I would have expected that it would make someone more susceptible to a cytokine storm. Curious to understand why that is not so. Thanks!

Do non-human animals experience psychological biases like the Sunk Cost Fallacy?

Posted: 26 Feb 2021 03:33 PM PST

Most of the time I hear about it in humans. For example, "I prepaid for a Hulu sub this month, even though there's nothing I want to watch I should watch something because I paid for it."

Does this happen with other animals? Like with food storage? Are they caught "throwing good money at bad money" but in their own way?

Can Someone Walk Me Through The Stages of an MRI Scan?

Posted: 26 Feb 2021 12:53 PM PST

I understand generally how it works, that's not what I'm asking.
But I take an MRI regularly and the question I ALWAYS am curious about is: exactly what is going on during an MRI? It's obviously not just one scanning mechanism, so I want to know what is every single stage of an MRI? What are all the different 'scans' going on? There's fast ones, high-powered ones, rapid-fire ones, and all sorts of other types of scans. Is it a different phyiscal mechanism? What is the purpose of each?
I really am looking for a detailed breakdown of how it works, and if possible, a visual representation of each stage (like: does it go from one side to another, does something spin, are there two of one thing, etc).

Thank you in advance, I realise that's a lot to ask for
