| Posted: 28 Apr 2018 08:54 PM PDT To my knowledge, various different brain tumors can have negative emotional impacts such as depression or anxiety, but if an individual already suffers from these illnesses, could a tumor have a reversing like effect? [link] [comments]  |
| What is the net greenhouse gas emission of agricultural causes? Posted: 29 Apr 2018 05:31 AM PDT Hi all, doing an economic report on how we need to reduce greenhouse gases without effecting the economy. I've done a few years of chemistry, so it was somewhat bothering me how people claim greenhouse gas is "created" (ie conservation of matter). Can someone with better knowledge of the topic explain whether or not my assumptions are justified: 1) Grass or wheat (grain) photosynthesise CO2 and water, "storing it" inside the plant matter 2) Cows digest said grass and wheat, releasing greenhouse gases into the atmosphere 3)The greenhouse gases is photosynthesised and Chemosynthesised, repeating the food cycle By this assumption, the long term net greenhouse gas emission of cow digestion is a lot less then initially assumed, as the emission results from the digestion of food created for the animals. The same can't be said for the CO2 output from cars, as gas and oil takes millions of years to form, resulting in an "increase" in the atmosphere. I obviously realise there will still be more greenhouse gas transferred into the atmosphere then there is consumed, but does anyone have any thoughts of how much this amount is? If I have made any massive fundamental errors please also correct me Thanks for helping my curiosity! Bonus question: Given cyanobacteria and algea account for 70-80% of O2 production why don't we just cultivate them to reduce greenhouse gases (hopefully no great oxygenation event 2.0) [link] [comments]  |

| Why are elements distributed non-uniformly in the earth's crust? Posted: 28 Apr 2018 08:52 PM PDT How do seems of gold or uranium end up in one rock formation but not another elsewhere? Why isn't the earth's composition uniform or closer to uniform? Is there something about our core or mantle that puts a little more uranium over here than over there? [link] [comments]  |
| Posted: 29 Apr 2018 04:47 AM PDT Does a positive index value of the NAO have the same effect on temperature/climate as a positive value of the AMO? [link] [comments]  |
| why is chemical sunscreen put in certain perfumes? Posted: 29 Apr 2018 12:09 AM PDT the other day I read the ingredient label in a cologne and it had "ethylhexyl/octyl methometoxycinnamate" which i'm pretty sure blocks UVB rays [link] [comments]  |
| If I wanted to travel to the Sun, at which direction do I point my thrusters? Posted: 28 Apr 2018 12:06 PM PDT In a ship that are in earths orbit around the sun. I figure we already have momentum, so if I pointed the thrusters in the opposite direction of my momentum. Then I would decrease my speed around the sun and gravity should pull me in. I think Or is it just as simple as pointing my engines away from the sun and head inwards? Like walking on one of the arms of a carousel towards the center. [link] [comments]  |
| what is the difference between our perception or thoughts and our subconscious? Posted: 28 Apr 2018 12:54 PM PDT its a very abstract thing to try and feel out the boundary between my own thoughts and the subconsciousness (that i can't access with those thoughts). are the thoughts just auxiliary and its all really just my subconscious, with those thoughts just bouncing around the brain but just don't go too close to certain areas that are too personal or traumatic, or just too complicated, sort of like how you can't think two thoughts simultaneously? OR, is it life that's just that complicated, and we're just helpless to understand it one thought at a time? or are thoughts not even quantifiable in that way at all; maybe I'm mixing thought up with perception, and if so, then would it just be my 'perception' that is unable to pierce the veil of my subconscious 'thought'? or in other words, can someone just explain what goes on when a human 'thinks'? or do we not actually think at all, in that way at least, in which case is this just whats called 'internal dialogue', that term where something like half of the population talks to themselves in a constant stream of thoughts but aren't crazy?

| Why does pouring water on a grease fire make it bigger? Posted: 28 Apr 2018 05:53 PM PDT I saw the post on r/WTF and it reminded me that I've always wondered. [link] [comments]  |
| Are there examples of cancers that have a normal copy of p53? Posted: 28 Apr 2018 02:12 PM PDT It's been said that over 50% of tumours have a mutation in p53, but I can never find examples of tumours that actually have an intact p53 protein? Can these tumours even exist? [link] [comments]  |

| Can Lactic Acid be considered an alcohol? Posted: 28 Apr 2018 11:02 AM PDT I was studying HS biology, respiration to be exact. Whilst solving the questions, I wondered the molecule structure of lactic acid. Once I looked at it, I realized it had a carboxyl group (like an acid) and an hydroxy group (like an alcohol). So can lactic acid be considered an alcohol as well as an acid? Edit: [link] [comments]  |
| How does the body make more blood after you finish bleeding? Posted: 28 Apr 2018 11:52 AM PDT As somebody who gets a lot of bad nosebleeds, especially during the winter, I've lost a lot of blood this way, and I've always wondered how more blood gets made once the bleeding stops [link] [comments]  |
| Why is the mass attenuation coefficient inversely proportional to density (mac = μ/ρ)? Posted: 28 Apr 2018 07:23 PM PDT Wikipedia definition: "The mass attenuation coefficient, mass extinction coefficient, or mass narrow beam attenuation coefficient of the volume of a material characterizes how easily it can be penetrated by a beam of light, sound, particles, or other energy or matter." Surely a denser material would make it harder for light to penetrate it? Therefore mass attenuation coefficient should be proportional to density? [link] [comments]  |
| How are mineral seedbeds created? Posted: 28 Apr 2018 03:08 PM PDT What minerals are in trees that get deposited into the soil? Why do certain trees prefer this? Edit: I'm being downvoted and I'm not sure why. This is my first post on here and maybe I'm missing something for my question? I'm learning about post fire forests and the texts mentions mineral seedbeds are produced after fire, but they never really mention what that is. Just that some trees prefer this and I don't really know what that means. I tried Googling it too, but again, most of my results just studies where some plants respond better to this type of soil, but not sure of exactly why or what it is. Thanks in advance to anyone who can help me understand. [link] [comments]  |
| Posted: 28 Apr 2018 06:08 PM PDT So I'm a high school freshman who hasn't yet taken chemistry. However, I do know that the amount of protons in an atom make it a certain element, such as one proton making an atom Hydrogen. So why does having one proton cause the atom to exhibit the properties of hydrogen? Are an atom's properties more dependent on their neutron number (as in different isotopes)? And what would happen if all protons were removed from an atom and how would someone do that? [link] [comments]  |
