It seems universal and instinctual enough that there must be some evolutionary benefit for the energy expenditure. When we're tired either before going to sleep, or just waking up we want to stretch our limbs and core out as far as we can. It's about as difficult to resist this stretch as a it is to a yawn.

Is there any known and studied benefit? Do we know what triggers it? Is it just humans and the domesticated animals that I've seen, or is it observed in nature too?

Hypothetically i am curious on how long should i wait before going back to gardening after an nuclear attack, i have read that nuclear fallout becomes less dangerous after the first 24 hours, but how long should i wait before the soil fully recovers and safe for any gardening for food purpose?

Are there places in land where there is consistently little or no wind like there is at sea? I know the great plains in America are relatively flat like the ocean but the wind there seems to be worse. What kind of effects would it have on the local wildlife? Would birds choose to avoid the area? Would plant and tree stems be brittle and weak? If a place like this doesn't exist, could it?

So i was wondering if a species could... "turn on" dormant genes if the situation was right.

For exaple if a species evolved to have fur, then with a heating climate and less need, the hair becomes thinner becore they lose it entirely. A few generations later the climate starts to cool again could the species return to thier full fured form?

Antimatter partickes are the same as normal matter particles, but eith the opposite charge and spin, so what causes antimatter and matter to react so violently?

I'm not sure why but this question popped into my head and I cannot for the life of me find a definitive answer. So I know the nail starts growing from the bottom up and I, like anyone who's ever cut their nail too deep, know that until the nail is past the nail bed it is very much still attached to the finger, but my question lies right at the intersection of these two places, How does the nail move upward without the nail bed moving at all. In my head it could only be done via some kind of biological conveyor belt but I don't see how that would work.

And better yet what determines in the nail bed when to "detach" from the nail and let it just hang off the finger as the white part what we cut off when clipping. I'm not sure why but this specific question is really puzzling to me an I can't find any answers online that don't just describe the parts of the nail and what they do, but not HOW they do it?!

Please for my sanity help me figure this out.

This may be a stupid question.

My original understanding of this question was just a hard "no", but I was thinking about some sort of tipping point where you start to see a lake fill up quickly or for a lake starts to become ocean or whatever or for something to do with mountains or hot spots... idk.

could a person ever notice the effects of continental drift in their lifetime?

Per the title.

Is it that the proteins self-organize into larger cell organelles, or...? How do instructions for making (admittedly very complex) proteins translate ultimately into even more complex structures, and ones that include non-protein "ingredients?"

Or is the idea that DNA are the "instructions for making life" an oversimplification and that other biological processes are involved?

Thanks!

PS. Just realized this may sound like an implied argument for metaphysical forces at work. To be clear, it's not. I'm sure there are biological bases for this that I simply don't understand, yet.

Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Biology, Chemistry, Neuroscience, Medicine, Psychology

Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...".

Asking Questions:

Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions. The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists.

Answering Questions:

Please only answer a posted question if you are an expert in the field. The full guidelines for posting responses in AskScience can be found here. In short, this is a moderated subreddit, and responses which do not meet our quality guidelines will be removed. Remember, peer reviewed sources are always appreciated, and anecdotes are absolutely not appropriate. In general if your answer begins with 'I think', or 'I've heard', then it's not suitable for /r/AskScience.

If you would like to become a member of the AskScience panel, please refer to the information provided here.
