- Will an Octopus Die If one or two of it hearts stop ? and Why ?
- Vast swathes of North America used to be an ocean, the Western Interior Seaway. If this is true, why are those lands not salted and inhospitable like other dried saltwater bodies that have left behind only barren salt pans?
- How far can the electricity spread when thunderbolt hits the ocean ? How close would you have to be to get hurt ?
- Would it be more fuel efficient to only ever fill the gas tank halfway?
- What was the diet of early humans? How did they know what foods were safe to eat?
- Do quarks have an electric or magnetic field associated with their fractional charge state?
- Are languages changing/developing faster or slower than they have in the past?
- What is the effect of pH on ion mobility?
- In the new Netflix documentary called "Our Planet", a Western Parotia bird of paradise changes it's eye color from blue to yellow during a mating dance. How?
- Is there any limit to how powerful a cyclone (hurricane or tornado) can get before physics prevent further growth?
- In theory, would it be possible to create a whole other internet where the addresses don’t start with letters “www”?
- What happened if you tried to exercise with early pacemakers?
- How does a sociologist isolate socially constructed vs innate differences between behaviors of different sexes, races, ethnicity, etc?
- How does space debris impact earth's environment and atmosphere?
- How does bacteria cause bleeding with a UTI (blood in urine)? Are they biting you?
- Transparency: Pass-through or catch and release?
- Why does conductivity in a material (almost) always exclude transparency? What makes transparent and conducting materials different from usual conductors?
- What “characteristics” allow cryopreservation of embryos to be “reanimated” in assisted reproduction, but make reanimating a cryo preserved adult human something that exists only in science fiction?

| Would it be more fuel efficient to only ever fill the gas tank halfway? Posted: 08 Apr 2019 08:23 AM PDT Gas must be pretty heavy, and adding that much extra weight into a car has to reduce the fuel efficiency to some extent. Would it be worth it to only ever fill the tank to half? [link] [comments]  |
| What was the diet of early humans? How did they know what foods were safe to eat? Posted: 07 Apr 2019 08:21 PM PDT What did they survive off of on a daily basis and beyond that how did they know what plants were safe to eat? [link] [comments]  |
| Do quarks have an electric or magnetic field associated with their fractional charge state? Posted: 07 Apr 2019 10:46 PM PDT I've heard these quark things have a fractional charge, but do they have a magnetic / electric field associated with this charge? Do they have a magnetic moment or electric moment? If a quark is accelerated somehow, would it produce a electromagnetic wave? Lastly, if you apply an electric field onto a proton, would the quarks polarize, like the way we learn that materials polarize when a constant electric field is applied across the material (the positive and negative charges move in a direction as to decrease the externally applied field)?

| What is the effect of pH on ion mobility? Posted: 07 Apr 2019 05:30 PM PDT I am interested in the physical and chemical mechanisms that come into play when analyzing the mobility of nutrients in soil for gardening purpose. [link] [comments]  |
| Posted: 07 Apr 2019 07:23 PM PDT Even more strange, I can't seem to find any references to this eye color change anywhere else on the internet, and yet I just watched it happen several times in its full 4K HDR glory. Can anyone elaborate on this phenomenon? Edit to include video link: https://youtu.be/rX40mBb8bkU?t=135 [link] [comments]  |
| Posted: 07 Apr 2019 06:39 PM PDT I've googled this a few times but a lot of the articles I found were not published by actual scientists nor did they feature any citations to scientist's articles. I figured since there's got to be at least a couple of meteorological super sleuths on here I could get a final, clear cut verdict. I don't care if there's no theory on this yet, simply knowing if there is and if so what the theory is would be pretty helpful for my amateur storm chasing and meteorological studies (I do this for leisure, I'm currently an undergrad in high school who just studies weather from inside his home in Missouri) and shed some light on what I could theoretically expect to see when a true monster strikes the heartland.

| What happened if you tried to exercise with early pacemakers? Posted: 08 Apr 2019 03:18 AM PDT Not 100% sure if this fits here because I'm not looking for numbers or figures, but I don't know where else to post. Studying physiology homework and the textbook tells me that modern pacemakers will artificially increase your heartbeat during exercise. That kind of implies that previous generations of pacemakers didn't do that. So if my understanding of that is correct - what would have happened if you did strenuous exercise that had a higher oxygen requirement that would usually trigger a faster heartbeat? Would you just get tired very quickly? Would you pass out from lack of oxygen? Would your body react the same way it would to anaerobic exercise (say, behaving as if you're sprinting when you're just jogging)? Would you wind up with more lactic acid/muscle pain? Or would something else happen? [link] [comments]  |
| Posted: 07 Apr 2019 04:44 PM PDT So for example, there is a large difference between the occupations women tend to choose and the occupations men tend to choose. How does a sociologist decide whether the differences are due to social constructs or whether men and women naturally prefer different occupations? [link] [comments]  |
| How does space debris impact earth's environment and atmosphere? Posted: 07 Apr 2019 02:01 PM PDT I know that it affects our space travel and satellites but does it have any affect on our environment on earth? [link] [comments]  |
| How does bacteria cause bleeding with a UTI (blood in urine)? Are they biting you? Posted: 07 Apr 2019 06:02 PM PDT How directly is the bleeding in a UTI caused by bacteria? Are they drawing blood directly from your ureter/bladder or are they causing irritation great enough to draw blood through some mechanism like a pH imbalance? The reason I am asking is because I am picturing little bugs inside poking with something sharp to draw blood directly. How else would the blood get there/ where is it coming from? My friend is thinking it's indirectly produced from irritation caused by some protein/chemical imbalance caused by the bacteria but neither of us have medical/biology background. [link] [comments]  |
| Transparency: Pass-through or catch and release? Posted: 07 Apr 2019 07:34 PM PDT When photons traverse through a transparent substance, do they actually pass through without interacting with the substance, or are they absorbed and re-released with the same direction and frequency? If they just pass straight through, then what causes photons to refract (deflect off of their straight line path). [link] [comments]  |

| Posted: 07 Apr 2019 12:52 PM PDT I have a rudimentary understanding that the main difficulty in cryo comes from the prevention of the formation of ice crystals which can damage cell membranes. Obviously an adult has orders of magnitude more cells, which means orders of magnitude more water which can damage cells when frozen and subsequently thawed. Can someone explain why we are able to achieve one and not the other? Is the difference at a molecular/cellular/ macro (tissue) level? [link] [comments]  |
