i've asked this a few times before but it never got answers, i'm extremely interested in the answer:
do animals recognize rhythm? so if i'm sitting on the couch with my dog, and we're both listening to music, we can both hear it. my hand rests on his back, and i start tapping my fingers to the beat of the music. does my dog recognize that the music and my finger tapping are connected/the same?
Have their been many studies done on ASMR? I'm curious about things like the prevalence and difference between people who claim the experience and people who do not. I've only been able to find one or two pretty generic studies.
How does a small birds survive freezing temperatures? Coupled with colder air at higher altitude, it seems like a sudden freeze would result in a lot of dead birds. Do they just huddle up and hope for a chance to get somewhere warmer? Do their feathers provide insulation like, per se, a squirrels fur?
Why can I pull up mental pictures of other people’s faces really well, but I can’t picture my own?
1.) What happens to individual atoms when a material flexes or bends? Do their bond angles and bond lengths change at all?
2.) What would happen if we could enclose helium atoms inside another material? I don't mean in bonding, I mean like a cage of atoms surrounding a helium atom (I believe there's a name for such a configuration but I can't think of it). Would the material be lighter? Would it have any unusual properties?
Ok I really want to know this because I want to be better informed when I talk about things and this topic is important.
Can someone explain to me the degrees of change that people are using when they talk about climate change? For example the sea level is going to rise a couple of inches in the next couple of decades. Who cares? 4 inches up the shore is not a lot. Is this relevant because of desalination? But it is spoken about in such an urgent way that I can tell that it's important.
Similarly, why is it a big deal if the planet gets like 2 degrees warmer? Is that important because of the upper margins when speaking about averages? Or?
It just seems like this situation is being spoken about in very small measurements that seem by themselves insignificant. I believe that climate change is real and dangerous and I want to understand the metrics being used to describe and discuss it.
Sorry for the lengthy post and thanks in advance.
Edit: Thank you so much for all your amazing and thought out responses. I am going to digest it all for a while but I feel a lot more informed now. (if anyone else wants to keep chiming in I'm always welcoming of more info)
How close are we to seeing applications of CRISPR in humans to help cure diseases (such as Cystic Fibrosis) and fight cancers? Also related to this, are there any firm ethics lines established and agreed to in the international genetics science community — eg no modification of an human embryo, which was a soft line that the [Chinese crossed in 2015](https://www.nature.com/news/chinese-scientists-genetically-modify-human-embryos-1.17378)?
I have ADHD. My psychiatrist asked me (a while back) if I had chronic ear infections as a child. I did. What is the link between childhood ear infections and ADHD? Is there any accepted theory about why there is a correlation between ADHD and ear infections?
What harm does a cold or flu virus actually do to the body?
All the unpleasant symptoms seem to be from the body's attempt to expel the virus: fever, sneezes, coughs, etc... But clearly we've evolved to view it as a threat.
What is something within your field of study that is considered "settled" that the general public considers controversial?
Why doesn't acid eat the container it comes in?
Some microorganisms can survive boiling water, e.g. the ones that inhabit hot sprints at Yellowstone.
Given many microorganisms that make us sick are susceptible to boiling, why isn't there more selection pressure on them to evolve to survive at higher temperatures thus thwarting our attempts to stop them from infecting us?
Why is it that I can't "cure" my dry throat by swallowing my spit?
So when we eat really spicy food, our tummy tum gets really violent and makes us want to shit all day. When we poop it out, our butthole feels burny. My question is, is that fecal matter spicy? Like if we ate our shit, would we need milk to tone the the heat?
