Domestic Short-haired cats are considered what a "true" cat looks like once imposed breeding has been removed. With so many breeds of dogs, is there a "true" dog form that would appear after several generations?

Can a drink actually be “more hydrating” than just water, or is that just made up to sell sports drinks?

Posted: 14 Dec 2021 06:35 AM PST

Basically title. How can something hydrate you more by adding electrolytes or salt? Surely the amount of water you're putting into your body is the only measurement of how hydrated you can be? I'm torn between "I don't know enough about electrolytes to question it" and generally assuming all marketing/advertisement is lies.

If HFCS is fructose and glucose, and raw honey is also mostly fructose and glucose, what makes HFCS *that* bad?

Posted: 13 Dec 2021 04:47 PM PST

Honey is often hailed as having medicinal benefits (or at least being not as bad as table sugar), whereas HFCS is in multiple nutritional black lists (figuratively) and is feared by many for its harmful effects being much worse than straight up table sugar.

Often the explanation is that HFCS has higher fructose which is the bad thing about it, when honey usually have similar if not even higher fructose content compared to glucose. So what gives?

I know that honey has enzymes, minerals and vitamins making it somewhat beneficial, but this doesn't change how the body absorbs and metabolizes fructose whether in HFCS or honey. So what's the deal here?

Is honey just as bad as HFCS or is HFCS not as bad as it is made out to be? Or am I missing something?

If Omicron can infect people who have had Delta, can Delta then carry on infecting people who have had Omicron, and both strains co-exist?

Can you train/exercise your ears to hear better?

Posted: 14 Dec 2021 06:19 PM PST

A while ago I heard someone I work with, who is a fairly smart person, talking to another coworker. He said, "I watch TV with the volume on low to train my ears so I can hear better."

Would this work?

Can sperm really live for 5 days in the uterus at ANY time during a woman's cycle?

Posted: 13 Dec 2021 09:16 AM PST

I have read a lot of posts from women (both trying to conceive and afraid of conception) asking whether or not it's possible to get pregnant at various times of their cycles.

E.g., "I had sex on Day 4 while still bleeding. Can I get pregnant?"

The answer I always see is that "yes you can because sperm can survive for upwards of 5 days in the female reproductive system."

However, I had thought that 5 days was only under optimal conditions (namely fertile window leading into ovulation). Is it true that sperm can easily survive for 5 days during menstruation?

Is there a good study on this? I haven't had luck finding it.

Could a black hole get 'clogged' or 'bottlenecked' by something sufficiently massive collapsing 'all at once'?

Is it possible for people to host two coronavirus variants (or more) simultaneously? That is, can the different variants coexist setting up shop in separate cells in the body, or is the mechanism such that only one variant can emerge and become the cause of infection illness?

Why can’t electric vehicles use total regen braking?

Posted: 13 Dec 2021 05:02 PM PST

Here is my example. A Tesla has two regen settings and you can do one pedal driving to a point. My question relates to the need for physical disc brakes and whether they're really needed. What is it that prevents using the motor as the brake? Is it legalities at this point? Does this generate too much electricity too fast for the battery to ingest? Is it the wiring?

I've heard that an electric drive motor could easily lock up the tires of a car at high speed so I don't think it is the motor.

What’s the fastest physical object? Something that has mass. From any reference point. Are there things traveling close to light speed opposite from something else close to light speed away?

Is there a direct relationship between fat (adipose tissue) and fat (the food type)?

Posted: 13 Dec 2021 04:36 PM PST

I understand that the body will produce adipose tissue when in a caloric surplus, and fat is quite caloric. But is there a more direct relationship between eating fats (butter, olive oil, avocados, etc) and producing adipose tissue?

why isn't the volume of molecules negligible in a real gas?

Posted: 14 Dec 2021 07:52 AM PST

i get that in an ideal gas the molecules have a very small volume in comparison with the actual space the gas moves in, so why not apply that same logic to a real gas?

Are there completely harmless viruses?

Posted: 14 Dec 2021 08:07 AM PST

Every virus we ever hear of - SARS, influenza, herpes, etc - causes some kind of health issue.

Are there also viruses that spread and live in human bodies that have zero negative health effects?

Why are large telescopes, such as NASA's James Webb, considered so fragile and extra precautions are taken before flight, but can survive the forces of acceleration and vibration from a shuttle launch?

Posted: 13 Dec 2021 09:43 PM PST

I've seen news outlets report on the "drop" that happened with the telescope, and how it delayed it a little bit. It seems like everyone is so worried about the fragility of the components within these telescopes and their parts, but how are they able to survive the sustained vibrations and forces of a rocket launch if people have to be so careful with it even prior to the launch?

Is it possible to predict if there may have been life on a planet based on its parent stars life cycle?

Posted: 14 Dec 2021 04:58 AM PST

In our solar system 5 billion years from now our sun will become a red giant scorching our planet and making any evidence that life that had existed a distant memory. Knowing that stars generally dictate the life cycle of their solar system, could we look at a star that's dying and predict with certainty that life may have existed on a distant exo planet within that solar system?

Is the geography under the Antarctic ice pockmarked in a grid pattern, and if so why?

Posted: 14 Dec 2021 05:10 AM PST

https://upload.wikimedia.org/wikipedia/commons/e/e0/AntarcticaRockSurface.jpg

Found the above while looking on Wikipedia for information about the news on the Thwaites Glacier. Was trying to figure out an approximate timeline for sea level rise if the dramatic words in today's science news (about the Thwaites Glacier iceshelf melting) become reality but that's apparently too much to ask (I should have known). Not sure if Earth science or Planetary science but I'm guessing that it has less to do with plate tectonics than ice/weathering/imaging artifacts.

Original paper that led to the articles I saw: https://agu.confex.com/agu/fm21/meetingapp.cgi/Paper/978762 - shelf collapse in 5 yrs possible, with slight acceleration of sea level rise after?

What is the fastest speed a small rock could be accelerated to naturally in a solar system?

Posted: 14 Dec 2021 03:46 AM PST

Lets assume you had complete control over a solar system, and through any combination of collisions, gravity assists, etc. you wanted to accelerate a rock the size of a baseball - how fast could you get it going?

I'm thinking of experiments like this one where impacts can potentially speed up an object much more than expected, though I don't expect a rock would survive this particular scenario. Is it possible a moon colliding or other violent/unlikely event could somehow end up ejecting a pebble near the speed of light?

How much was the per-head CO2-footprint in different countries during their first (or hardest) lockdown in comparison to 1 year before during exactly that period? (+ bonus questions!) --> Hope to find some environmentalist help here <--

Posted: 13 Dec 2021 11:54 PM PST

_________

I hope there are some sort of standard factors for at least some of the partial questions. Hopefully also any that are worldwide acknowledged and are comparable.

In order of my personal interest, thankfulness for answers and (imo) gradation...

1. data on carbon-footprint: How much CO2 did each person of the country of your choice use in the specific time of the lockdown and exactly one year before? Which sectors of public/common goods and individual expenses have changed how much in that time?

bonus level 2. data on industrial sectors: Which industry in your country changed productivity (and therefore most often carbon footprint) to what amount? (Which segment has changed with delivery services to which amount?)

total bonus level 3. How much have people changed psychologically? What are significant factors (besides forms of violence) to describe the mood in a society? Which were outer factors (so there could be a relation also i.e. to how rich / poor a person or family changed in society)

Pls also hit me up with interesting thoughts of yours regarding the idea.

Have a great day and thanks for any involvement in advance :)

____________

Just a thought on how people could perceive what a reduced (in my final question: complete transition to degrowth or circular) economy in society could imply for their everyday life: I'd like to create a comparison between life standards in lockdown and 2019 (business-as-usual scenario, referring here to pre-corona). I think it could create an interesting chart, in order to make socio-economic sufficiency more relatable to how that feels as a society (and imo also to some extent between individual life standards and a vast economical shutdown, never seen before); I think mostly about transportation, production of closed businesses during lockdown or the whole culture/event-based segment and consumption as felt by everyone around the globe. Therefore, it would also be necessary, that industry-comparison during lockdown would have to be taken into consideration. Then, people could probably better understand, which reduction of the carbon footprint means which degree of sufficiency in the world.

OT: I hope you find my question(s) also very interesting, once you started thinking about it and I wanna know really bad now (also since this is my first post)!)

Wanna know (at least some comparable...? numbers (at best make a comparable chart for it), so people could compare their and the industry's footprint usually and during the probably lowest of all production rates possible in the quiet lockdown world economy.)
