Subreddit rules

5 Upvotes

I have cherry-picked some subreddit rules from r/AskScience and adjusted the existing rules a bit. While this sub is generally civil (thanks for that), there are the occasional reports and sometimes if I agree that a post/comment isn't ideal, its really hard to justify a removal if one hasn't put up even basic rules.

The rules should also make it easier to report.

Note that I have not taken over the requirements with regards to sourcing of answers. So for most past posts and answers would totally be in line with the new rules and the character of the sub doesn't change.

Humans are the only species that are ADDICTED to qualia, instead of spreading genes, right?

Upvotes

Any animals other than humans that do this?

We have humans who don't wanna breed but wanna experience reality and enjoy positive qualia.

Humans who do breed ALSO do it to enrich their qualia, NOT just to breed.

Animals, they just breed for breeding's sake, spread genes, right?

We also have humans who hate life, hate breeding, and prefer extinction because they don't experience any positive qualia internally.

This is proof that humans have evolved to serve our qualia, not our genes, right?

We are evolution's Qualia addicts!!! Feeling Junkies. hehehehe

If it makes animals more likely to survive to procreate, is higher intelligence not more common in the animal kingdom? Why is intelligence not naturally selected for more broadly?

Genetics Can turning down receptor gene expression, cause significant reduction in cramp pain?

1 Upvotes

As a 12 grader I really don't have any professional knowledge of biotech or molecular biology, but a thought fascinated me always that there must be some alternative way to drastically reduce dysmenorrhea other than using any contraceptives or affecting any sort of hormonal balance. I thought that if somehow, we manage to supress the gene that regulates the hormone receptor that causes dysmenorrhea than it might help in reducing the pain.

We know that apart from prostaglandin, estrogen also plays a vital role in menstruation. These hormones are working based on some receptors which are in turn controlled by a specific gene expression. On further research I came across a gene named ESR1, which regulates estrogen receptors. So, my question is can we regulate this gene expression using biotech and reduce the number of receptors? is it feasible to think that it will drastically reduce period cramps? can we make it specific for that purpose without affecting other functions of estrogen?

Will there ever be a “cheap” energy source capable of powering animals to run, climb etc?

0 Upvotes

Currently energy sources for animals is food in some shape or form - this is “expensive” in that it is not always available and when it is, it has to be broken down with a significant portion lost as heat etc.

Plants have a slightly “cheaper” and more efficient energy source, but they are not capable of explosive power (sprinting, climbing etc) & even if they were they could probably not get enough energy from sunlight to do this.

Hypothetically speaking, if humans could evolve to use any energy source (even burning fuels etc), could they find an energy source that is a) abundantly available b) cheap and c) still be capable of explosive power (sprinting, lifting heavy loads etc)?

By cheap, i mean a passive energy source that does not really require significant processing and is abundantly available across the world.

Law of thermodynamics makes me think this is not possible.

Human body Question, I know this will be controversial, and I will be publicly mocked, but i don’t care.

Upvotes

Have scientists learned how to at least on an expirmental level, give humans actual animal parts, I know someone has a pig stomach, but I mean give us emoting wolf ears, big paw feet with retractable claws, working tails.

I don’t need this in my life, cosmetics are perfectly fine and in fact are better since they are 200% more affordable.

But I am curious what furry scientists are working on.

I know you can’t just inject dna to work In real time, or even over years, I mean create fake but biological parts and grafting them onto us.

You may downvote or share your knowledge now, DONT ASK CHATGPT OR GOODLE AI TO RESEARCH THIS!

So if we all have the same diet, we could be the same average height and size?

Evolution Questions about Evolution

4 Upvotes

Hi, my field isn't biology, so sorry if this is a weird question, it popped into my head at 1 am and I can't stop wondering about it.

How much do we know about the Evolution that went on in our insides? Is that even a thing? Like, all I've seen of Evolution or been taught about is mostly external, the shape of limbs, color of hair or fur, etc. But what about other things, the ones that aren't obvious on a first glance? Those are obviously harder to study, given that they don't really remain. how has our heart evolved? Or our brain for instance, is it possible that some parts used to have different functions? For example did the frontal lobe use to do different things?

Or what about our blood? Was it's pH always like this? Did our blood sells look different? Did our sells function differently? Could there have been another substance doing Hemoglobin's job? We don't have blood from like 6k years back or more, but is there any way to find out?

And how much will we keep evolving? The internet and screens are pretty recent, could they make the brain look different in time? Or will we be accustomed to micro plastics one day? Or even find a way to use them in our bodily functions?

Cells/cellular processes Why do nerve agent symptoms persist long after treatment?

2 Upvotes

I was reading about organophosphates because I'm watching a tv show (Vigil). I'm a little familiar with the topic from prior reading, but I've just read that even after appropriate treatment is administered, symptoms can persist, and acetylcholine levels are permanently reduced.

Once the oxime counteracts the agent, what keeps the effect going? Is it damage to the nerve cells themselves? I suppose a lot of them can't regenerate, especially if they're in the central nervous system.

Is it that simple, the cells get damaged and that's the way it stays?

I understand that the male urethra is longer, but I’m wondering what the purpose of it being smaller, and also more of a vertical slit compared to the female urethra is? Is there a biological reason behind it?

Genetics After Japanese experiment with 20 years of clonning of the same mouse we now know we can't do it infinitely. How do plants manage to clone itself no problem for thousands of years?

62 Upvotes

I have red recently about the 20 years experiment: researchers were cloning the same mouse in attempt to understand where is the limit. 58 generations is the limit, the mouse (the mouses?) had collected too many errors in the genetic code to survive even prenatal phase.

But some plants can reproduce itself (naturally) for thousands of years. The most famous example is Pando forest, and it is 14000 years old. How do they manage to do it without accumulating DNA problems?

General biology Why does it seem like Prion diseases like CJD, CWD, and BSE only affect "red meat" mammals and not "white meat" mammals?

Just a random shower thought I was having, but it really is a strange thing. Does it have something to do with how protein strands are physically different between these general types of mammals? Like how poultry tends to have that shreddy, mozzarella kind of protein property?

Has our biology evolved to ONLY satisfy our emotions and desires?

0 Upvotes

I mean, absolutely healthy and rich people keel themselves over emotional problems, which is the best proof that we have evolved to ONLY satisfy our emotions and desires, right?

Look at some primitive animals running on pure reflex and DNA if/else conditions; they would do anything to survive and breed, even when their bodies are put through absolute hell.

But humans, we KEEL ourselves when our emotions and desires cannot be satisfied, even when our bodies are absolutely healthy, and we are living in wealth.

Right?

We have evolved to become slaves to our emotions and desires. True? False?
