- When octopus/squid/cuttlefish are out of the water in some videos, are they in pain from the air? Or does their skin keep them safe for a prolonged time? Is it closer to amphibian skin than fish skin?
- Does the size of electromagnetic waves in the visible light spectrum make it impossible to focus a conventional microscope on things close to or smaller than the wave's magnitude?
- Can anyone tell me why was uranium so light Dimitri Mendeleev periodic table?
- Other than radiation, fusion, and fission, are there any natural processes which alter atoms from one element to another? [Chemistry]
- Does a binary star system have interacting Goldilocks zones?
- Is USB charging more battery friendly than charging with AC charger?
- Considering surface tension, how do <1 cm insects consume water safely?
- Did dinosaurs shed their skin like modern reptiles?
- How exactly does fluticasone nasal spray work?
- If hair is made out of keratin (protein), why does heat-curled hair go back to normal after you wash it? What is it about the water that helps hair go back to normal, and why is the protein in hair not permanently denatured?
- How is a rocket able to lift itself off the Earth and escape gravity if total energy is conserved?
- Why is elastin elastic?
- Why does the falcon 9 heaven rocket have a mist coming over it at launch?
- If you dig straight down, do the rocks age with depth?
- Are there clues in the geologic record as to when chunks of subducted tectonic plates have snapped relatively clean from the parent plate?

- How are plants selectively bred/grown?
- Would it be possible to independently determine what 1 volt is without a frame of reference?
- If you build a higher tolerance to alcohol does this mean it takes more alcohol to get the same BAC or just more alcohol to get the same effects?

| Can anyone tell me why was uranium so light Dimitri Mendeleev periodic table? Posted: 09 Feb 2018 01:36 AM PST I was reading this article. The article stated that the atomic weight of uranium in Dimitri's periodic table is about half of what we know. I was wondering why? [link] [comments]  |

| Does a binary star system have interacting Goldilocks zones? Posted: 08 Feb 2018 04:23 PM PST Do binary stars have individual planet systems, or do the two share one? Would a binary star system have any advantages or disadvantages in terms of potential life formation in the "Goldilocks" zone? [link] [comments]  |
| Is USB charging more battery friendly than charging with AC charger? Posted: 09 Feb 2018 06:12 AM PST I've seen it mentioned a couple of times here and there, that when you charge your device with a USB cable (connected to your computer), the battery will get less hot than when you charge it with an AC charger, which affects the battery life. Is that true and doesn't that mean that fast chargers are actually bad for your battery on the long run? [link] [comments]  |

| How exactly does fluticasone nasal spray work? Posted: 08 Feb 2018 09:14 PM PST The stuff immediately makes my allergy symptoms go away. I know it's a corticosteroid but I can't find an actual breakdown of what it's doing once inhaled. [link] [comments]  |

| If you dig straight down, do the rocks age with depth? Posted: 08 Feb 2018 04:30 PM PST Say if you have a vast mineshaft. Are the rocks at the very bottom as old as the Earth itself? Do the rocks become younger as your tunnel upwards? [link] [comments]  |
| Posted: 08 Feb 2018 08:01 PM PST Like large crustal upheavals, rebounds, something like the Great Unconformity being representative of this type of event? I'm wondering what magnitude of earthquake could occur in a region where a few hundred miles of a tectonic plate might have broken off in successive events that caused widespread "really big ones" generated from far deeper than those relatively close to the surface.

| How are plants selectively bred/grown? Posted: 08 Feb 2018 07:21 PM PST I've heard from many times that plants and produce like the Carolina Reaper are "invented" or selectively bred. I understand how this can occur when breeding animals, but how on earth can you do this with plants? And in theory, if somebody wanted to, could they make apples as sour as something like sour skittles? What are the limitations, if any, to what can be bred? [link] [comments]  |
| Would it be possible to independently determine what 1 volt is without a frame of reference? Posted: 08 Feb 2018 05:00 PM PST I was thinking about all those 'you get sent back into the past with your phone and...' posts, and making a simple water wheel powered generator is easy enough to recharge it, relatively speaking, but how would you regulate it to +5v DC? I did a quick glance of Wikipedia and it seems to not be something that can even be easily approximated, like 'one Mississippi' for a second. So, basically, how would you be able to verify the voltage of a generator without a frame of reference since the volt was historically defined comparatively? [link] [comments]  |
