- How many times has the average drop of water been through an animal kidney in the history of Earth?
- Coming from a 3rd year electrical engineering students perspective, I know how static electricity works but what I don't know is why it works essentially. What I'm asking is; why do some materials hold a better charge than others and while one material likes to gain a negative charge, Visa versa?
- When discussing properties of sound, is attack and decay included in the construct of timbre/quality?
- Can stress and anxiety increase body temperature?
- Does violent media affect how people affect how people react to real world violence?
- How, exactly, is electricity and magnetism related?
- Chemical analysis before 1973?
- Where does the flap-flap sound of a helicopter come from? Do all helicopters sound the same?
- How did we measure the mass of the Dwarf Planet Eris?
- How does a cell check its DNA during cell checkpoints? What DNA does the cell check its own DNA against?
- Where does the energy in synchrotron radiation come from?
- How evenly does CO2 spread out in the atmosphere, and are there regions were the level is a a significantly higher levels?
- How earthquakes affect rivers, how drastic can be the change in the flow and the structure of a river ? Are there some interesting examples recorded of river changing after an earthquake? Or maybe there are examples of a river going of its original course for large distances after an earthquake?
- If matter cannot be crated or destroyed, than how does anything exist?
- How do we know how many isotopes exist in the universe for an element, and their percentages, to determine the atomic mass? As we discover new isotopes, does a printed periodic table become obsolete because that element will have a new atomic mass?
- Why do prunes have more sorbitol than plums?
- Is the olfactory system more active in a monkey than in a human, relatively speaking?
- Why can't we solve for the wave function of another element than hydrogen?
- How exactly does a medically induced coma aid recovery?
- If albino plants usually die from lack of chlorophyll, then how does the Caladium plant survive with white leaves?

| Posted: 03 Oct 2019 08:51 AM PDT By Visa versa I mean another likes to give away electrons. I figure it has to do with surface area in some instances like with fur or styrofoam but with glass and other non conductors that can have the same surface area I don't know where these extra electrons or holes are stored.

| Does violent media affect how people affect how people react to real world violence? Posted: 04 Oct 2019 02:32 AM PDT Basically what the title says. Have there been any studies on how media affects how people's reactions when exposed to real world violence/combat situations/any other kind of traumatic experience that they could have been exposed to in the aforementioned media?

| How, exactly, is electricity and magnetism related? Posted: 03 Oct 2019 09:37 PM PDT We'r cal it electromagnetism, right? So through what medium are they related? Electric current creates a magnetic field around it right? How? Why? [link] [comments]  |
| Chemical analysis before 1973? Posted: 04 Oct 2019 05:11 AM PDT Hey all, I've been doing some reading on the Ames test that popped up in the 1970s, but can't seem to find any information as to how chemicals were tested before that. Also, in the research articles I've looked at they've mentioned that 'several' bacterium are used in Ames testing, but I haven't found anything other than E. Coli and Salmonella. Any information on either of these two topics would be greatly appreciated. [link] [comments]  |
| Where does the flap-flap sound of a helicopter come from? Do all helicopters sound the same? Posted: 04 Oct 2019 04:21 AM PDT Sometimes helicopters have a rhythmic sound sometimes a swooshing. Where does the rhythm come from? What causes the sounds? Are there more silent helicopters? [link] [comments]  |
| How did we measure the mass of the Dwarf Planet Eris? Posted: 03 Oct 2019 09:54 PM PDT I found online that we were able to discern the mass based off of it's moon Dysnomia's Orbit, but how do we get a measurement within a 2% margin of error without either flying out a probe to test, or knowing the mass of one of the celestial bodies?

| Posted: 04 Oct 2019 05:26 AM PDT Does a cell check its own DNA against that of its neighbors? Or perhaps the cell that it was made from? [link] [comments]  |
| Where does the energy in synchrotron radiation come from? Posted: 03 Oct 2019 09:43 PM PDT If I have a permanent magnet and a beam of electrons passing by it the electrons will be accelerated and thus emit radiation. This radiation obviously contains energy so some other part of the system must lose energy. [link] [comments]  |

| Posted: 03 Oct 2019 05:06 PM PDT I've seen two chemistry teachers explain atomic mass by saying it's a calculated average of all the isotopes in the universe and their available percentages. What I can't figure out, even by Googling, is how we know the specific percentages of abundance for these isotopes? For example, Chlorine, has a natural abundance of 76% Cl-35, 24% Cl-37, and trace amounts of Cl-36. How'd we get those percentages? [link] [comments]  |

| Is the olfactory system more active in a monkey than in a human, relatively speaking? Posted: 04 Oct 2019 01:08 AM PDT I've learned that a larger percentage of the brain in monkeys - and I guess, other "less complex animals" (I dislike that term) as well - is dedicated to the sense of smelling, than in humans. Hence my question, title. Is this a reasonable conclusion to draw? Thanks. [link] [comments]  |

| How exactly does a medically induced coma aid recovery? Posted: 02 Oct 2019 09:03 PM PDT Assuming it's just to let the body 'heal itself', why not just go with standard bed rest? Or is it that it allows for more procedures to be done without weeks of bedrest between them? [link] [comments]  |
