Will a second covid infection necessarily be milder?

Posted: 08 Aug 2021 01:57 PM PDT

If someone gets infected with mild illness, recovers and also 6 months pass (no more antibodies) and then get infected again, will the immune system still necessarily react better (mild/even milder illness)? What if the second infection was a new (more dangerous) variant?

Does air-conditioning spread covid?

Posted: 09 Aug 2021 12:35 AM PDT

I live in India and recently in my state gyms have opened but under certain restrictions, the restrictions being "gyms are supposed to operate at 50 per cent of capacity, shut down at 4 pm, and function without air-conditioning"

I don't have problem with the first 2 but Working out without ac is extremely difficult especially when the avg temps is about 32C here with 70-90% humidity. It gets extremely hot and is impossible to workout.

Now my main concern is does air-conditioning really spread covid? is there any scientific evidence for this?

Also my gym has centralized air-conditioning

How does the immune system defend from airborne infections?

Posted: 08 Aug 2021 02:24 PM PDT

If I understand things correctly: COVID-19 attaches to ACE2 receptors available in your airway.

So it doesn't need to go through your bloodstream at any point to cause an infection, then once it infects a cell, it releases a protein that suppresses that cell's ability to release cytokines, which is responsible for signalling the immune system.

So does that mean that each successful infection is able to complete its life-cycle, or does the body have a way of defending from this?

Also, does immunity/antibodies play a factor in such cases?

What are the solutions to prevent/reduce wildfires?

Posted: 09 Aug 2021 02:54 AM PDT

Obviously there is a lot of talk that this is all prompted by climate change and we should reduce our emissions, but that's something that won't stop wildfires occuring next year for example. I'm just wondering if Greece/California/etc could do some activity to reduce wildfires from occuring next year, once they get the current ones under control.

How much, if at all, have covid vaccines been improved since public release?

Posted: 08 Aug 2021 07:33 AM PDT

This question applies to the vaccines available to the public. Are we still on version 1.0? Have formulas been improved as more variants are researched? Have we even made it to 1.0 considering that they were released under emergency release guidelines?

Here in the US I only hear about Pfizer, AstraZeneca, and J&J. What are other promising vaccines and how do they stack up to the 3 I mentioned? Are other less reputable countries, like China and Russia, reporting advances in their vaccines and has anyone been able to verify the claims?

Why is Fosbury-flop the most efficient way to do high jump ?

Posted: 08 Aug 2021 02:18 PM PDT

While doing some research about it I saw that it allows the jumper to keep his center of mass below the bar. But in pole vault they also keep their center of mass below the bar but with their body facing the bar.

If one approach is more efficient than the other to keep its center of mass below the bar, why does high jumper don't adopt the technique of pole vaulter (or vice versa) ?

What was wrong with the design of the control rods in the Chernobly reactor?

Posted: 08 Aug 2021 11:33 PM PDT

As far as I understand, the control rods were made of boron, a strong neutron absorber, and their tips, which were seperated by a small space from the boron part, were made of graphite. The graphite slows the neutrons and thus increases the reactivity when it is between the fuel rods.

According to what I see in the images on the internet, when the control rods were fully withdrawn the graphite tips were still inside the reactor and acted as moderators favouring the reactivity. As soon as the SCRAM button was pressed, the rods started travelling downwards and the boron parts started to enter the space between the fuel rods. I read that the graphite tips created a local temperature increase at the bottom of the reactor which started the catastrophic chain of events. My question is: why were there no such a local temperature increase prior to SCRAM if the graphite tips were still inside the reactor, between the fuel rods. Am I wrong by saying that the tips were already in the reactor somewhere in the middle before the SCRAM started?

What caused the largest earthquake and what was its magnitude?

Posted: 07 Aug 2021 07:47 PM PDT

The strongest measured earthquake was 9.5 on the Richter scale (Valdivia earthquake, 1960). This event triggered numerous tsunamis across the Pacific, including a 25 meter (80 ft) tsunami in Chile, and an 11 meter (35 ft) tsunami in Hawai'i. Nearly 1700 people died (including casualties from the tsunamis) and more than 2 million people were rendered homeless.

But this isn't the worst earthquake we know about.

Millions of years ago, a magnitude 12 earthquake permanently altered the shape of our planet and triggered volcanic eruptions around the globe. It can be difficult to imagine how devastating a magnitude 12 earthquake is, so consider this: any place you could have stood on Earth that day would have felt like a magnitude 9 earthquake. This event is known as the Chicxulub Impact, and people remember it for wiping out three quarters of the species on Earth—including the dinosaurs.

But that still isn't the biggest earthquake Earth may have experienced.

The Giant Impact Hypothesis says that the earth's moon may have been formed when a Mars-sized planet ("Theia") collided with proto-Earth around 4.5 billion years ago. Here's an animation of what that might have looked like. Sources don't really describe this event in earthquake terms, but I have a difficult time imagining an earthquake larger than one which could create a moon.

What was the magnitude (Richter scale) of the largest earthquake, and (if it wasn't the Theia Impact) what caused it?

is there always an antibody for all types of antigen?

Posted: 07 Aug 2021 09:10 PM PDT

in the case of humoral immunity, I have been taught that when there is a pathogen or virus the antigen of that virus binds to b cells with complementary receptors or antibodies. the B cell then phagocytes the pathogen, presents an epitope which now makes the B cell an APC (antigen-presenting cell). after the B cell display this epitope T helper cell bind to this epitope secretes interleukin, which influences the B cells to clone and differentiate into plasma and memory cells. Plasma Cells will develop antibodies against that specific virus and neutralize it. however, I was wondering what about when the body encounters a new virus? does the antigen of that virus still find a complementary antibody/receptor on the surface of a B cell? if so how is that possible if the body never encountered that virus before? can someone explain to me or send me a link that explains how exactly are antibodies made against viruses that the body never encountered before

Why isn't water used in hydraulic applications like vehicles?

Posted: 06 Aug 2021 09:55 AM PDT

If water is generally non-compressible, why is it not used in more hydraulic applications like cars?

Could you empty the brake lines in your car and fill it with water and have them still work?

The only thing I can think of is that water freezes easily and that could mess with a system as soon as the temperature drops, but if you were in a place that were always temperate, would they be interchangeable?

Obviously this is not done for probably a lot of good reasons, but I'm curious.

With such a high r0, why didn't measles just burn itself out?

Posted: 06 Aug 2021 12:14 PM PDT

I've seen speculation floating around the internet that we will get to herd immunity faster with the delta variant because it spreads so quickly, but I wonder even if that is the case, why didn't we develop enough herd immunity naturally for measles to simply burn itself out (for reference, measles has an r0 of 12-18 compared to the delta variant's 5-9.5). I guess I'm generally curious as to why some viruses burn themselves out (or mutate to become far less deadly, like Spanish flu) but others do not. Thanks r/askscience!

Does the COVID vaccine inoculate against the RNA sequence or the protein sequence?

Posted: 07 Aug 2021 06:46 AM PDT

A virus is an RNA, or less commonly DNA, sequence that gets translated into a protein sequence. From what I can remember a virus consists of at least two genes, a polymerase (pol) and an envelope (env). In theory we can have multiple RNA/DNA sequences that code for the same polymerase and envelope proteins. Does the vaccine inoculate against the RNA/DNA sequence or the protein sequence?

Also, are there multiple variants of the pol and env genes that code for the same protein sequence? For the virus to replicate, I assume there has to be a certain protein sequence. As the virus replicates it mutates. If the pol gene has a leucine it can be coded by the triplet UUA, uracil, uracil, and adenine. The gene could mutate to CUC, cytosine, uracil, and cytosine and still translate to leucine. This may still be functional, but not be protected against. If the pol and env genes do have multiple DNA/RNA sequences, can we just inoculate against the protein sequence? Would we be able to eliminate the DNA/RNA of the virus with RNAase or DNAase and not damage the protein sequence?

Do we have any data about how often COVID causes anosmia or hyposmia and how long it tends to last?

Posted: 06 Aug 2021 05:43 PM PDT

I keep hearing that COVID often causes anosmia and it's usually talked about as occurring in 'mild' cases.

As someone who has had long-term anosmia and hyposmia in the past from other causes, this description of the condition... really grinds my gears, I think is the technical phrase. Anosmia and severe hyposmia are debilitating and drastically reduce QOL.

If COVID caused temporary - or permanent - blindness, we wouldn't be calling it mild.

Anyway, what do we know about the frequency and duration of this symptom of COVID?

Is it possible to to model and predict COVID-19 variants and their effects ahead of time?

Posted: 06 Aug 2021 11:41 PM PDT

And if so, is anyone working on it?

I keep reading news all the time like, say, DeepMind's fantastic success recently with using AI to predict protein folding to roughly atomic accuracy. I don't know biology, really, but I gathered that was a big deal.

So I wonder: do we still lack the tech and/or knowledge to randomly explore the state space of potential COVID-19 mutations and be able to have a good enough guess at their characteristics that we could flag potential problematic variants for further review? Even if the prohibitive factor is the enormous range of possible mutations, I'd think a random search would be still be useful inasmuch as that's how the actual disease operates, so it could at least hint at which variants are particularly likely to emerge.

And it seems like it would be nice to know whether any real monsters are lurking around the corner, if such a thing were possible. If it's not currently possible, why not?

There are 'mutations' of the COVID 'delta variant'. P681R increases the viral load.

Mutation L452R may perform a similar function by thwarting antibodies. At what point does the 'delta variant' become the 'epsilon variant'?

Does the brain learn more when it succeeds or when it learns from a failure?

Posted: 05 Aug 2021 11:13 PM PDT

I am getting conflicting answers:

We learn more from success because when we succeed at something we already know, it reinforces the connections between our neurons, and when we succeed at something new, it sticks with us because it's novel. Success also activates our reward system, which makes our brains want to keep succeeding at that thing. You can use muscles as a metaphor: Every time you use a muscle, it gets stronger, just like every time we use our brains, the connections between our neurons get stronger.

We learn more when we fail and take the time to understand why. This is because when we realize that we did something wrong, our brains put in extra effort to strengthen neurons that make the correct associations. You can use muscles as a metaphor: If you want to grow a muscle, you have to stretch and strain it. You don't do things that are easy for your muscles to do. You do things that your muscles struggle with. This helps your muscles grow stronger. The same goes for your brain. The more you fail and learn, fail and learn, the stronger it gets.

Maybe one is true but the rationale used isn't accurate. I think it's funny that both ideas use a muscle metaphor.

Why does biological matter not rot under specific circumstances?

Posted: 05 Aug 2021 11:23 PM PDT

I know this is an odd question but the item in mind that brought the question up was egg tempera.

Egg tempera is a primitive form of ink composed of egg yolk and pigments.

Egg yolk decomposes and rots over time, correct? We all know how bad rotten eggs smell.

So why then does egg yolk not rot when it's made into egg tempera? In theory, shouldn't the ink decompose over time and lose its composition as the egg yolk breaks down?

As far as I know, the egg yolk itself is still biological in nature, so why does adding certain chemicals suddenly make it stop decomposing?

Upon further reading, I see that egg tempera can "rot" if not handled properly. But, if handled properly, it's considered stable, permanent, and unable to decompose.

So what prevents the decomposition there??

Another example is animal glue, glue made from melting animal hide. It is 100% biological material that doesn't necessarily show decomposition. Why not?
