| What is the biggest distinguishable difference between Alzheimer's and dementia? Posted: 04 Jun 2016 06:33 PM PDT I know that Alzheimer's is a more progressive form of dementia, but what leads neurologists and others to diagnose Alzheimer's over dementia? Is it a difference in brain function and/or structure that is impacted? [link] [comments]  |

| Are the intestines "in order"? Posted: 04 Jun 2016 08:09 AM PDT Ok, so this might be a strange question, but every time you see a depiction of the intestines it looks like a rope, that you try to fit into a small place without properly tangling it up. And if people in movies,tv etc. are severely injured, their belly sliced open and their intestines fall out, they kind of hang out of there like a rope. So my question is, if that was to happen, is there any order or system to put in back in in surgery or do you just try to "make it fit"? Please excuse the informality of the language, I just tried to paint an accurate picture of my problematic understanding. These depictions are meant: NSFW !!! And this one, of a man with his intestines hanging out: AGAIN NSFW NSFW [link] [comments]  |

| [Biology] Do I have the same DNA throughout my whole life? Posted: 05 Jun 2016 01:27 AM PDT If we compare my DNA when I was a baby with the DNA I will have when I'm old, would the two be different? [link] [comments]  |
| Posted: 04 Jun 2016 09:08 AM PDT Google didn't understand what I meant. Is there a name for this type of statistical calculation? If I had any knowledge about programming, I'd have the program randomly pick 10 numbers, keep track of them, but rerun the random drawing of 10 numbers until all numbers are accounted for and then stop. The number of runs it made reported at the end. Do this enough times and I think we'd get a nice curve. However, if there was a way to do this using a formula, it would be much nicer. I know they can calculate the probability cloud of an electron in an atom and that was not by brute forcing it but by using advanced math. I'm hoping someone knows of a way to do the same thing in this scenario. And if it has a name, I'd like to know it. [link] [comments]  |

| Posted: 04 Jun 2016 03:17 PM PDT If not, is there enough space to write how many digits are in the number of digits in Graham's number? If the answer is still no, then how many iterations would it take before arriving at a number small enough to write? [link] [comments]  |
| Posted: 05 Jun 2016 01:43 AM PDT From my understanding of the history of the Earth, it started out as just a big rock covered in lava (magma?) some-billion years ago. And then, a few billion years later, it had some water, which then held life. Now, where the life came from is a question for another time. But, where did the water come from? [link] [comments]  |
| Does the Time you Choose to Sleep at Have an Affect on your Health? Posted: 05 Jun 2016 03:46 AM PDT Growing up in an Asian family, I was told that sleeping and rising earlier was good for you. For example instead of sleeping at 12 and waking at 8, I sleep at 10 and wake up at 6; the total amount of time I sleep does not change, but the time period that I choose to do so does. I could not find any reliable sources on the topic and I am wondering if this is true or a myth. [link] [comments]  |
| Can someone explain the concept of gravitational potential between 2 masses? Posted: 04 Jun 2016 08:00 AM PDT I am struggling with the concept of gravitational potential. I know that by definition it is the work done in moving a unit mass from infinity to a point in the gravitational field (GPE per unit mass), but I don't truly grasp what this means and its significance. I also don't really get how gravitational potential is defined between 2 bodies, such as the earth and the moon. If we talk about bringing an object from infinity into the gravitational field of Earth I can visualise that, but how do you define the potential at a point where 2 fields act (such as that of the moon and the earth)? Where is 'infinity' in this case? Is there a point of 0 potential between the 2 bodies, where essentialy the strengths of the gravitational fields are equal and there is no resultant force on a body at that point, so no gravitational potential? I am only doing A2 physics (pre university) so a simple explanation will suffice. [link] [comments]  |
| Do other animals see face patterns in inanimate objects like humans do? Posted: 04 Jun 2016 09:48 AM PDT I forget the name, but I'm aware of the phenomenon where people see faces in things that aren't really faces. Last night, I was wearing a shirt with my school's sports logo on it, a flat depiction of a large cat. My Dad jokingly held up our cat to look at the cat on the shirt and she didn't really react to it at all. This made me wonder whether or not she even recognized the collection of flat, solid colors on my shirt as the face of a cat in the same way we do. [link] [comments]  |
| Posted: 05 Jun 2016 06:59 AM PDT For example, I weigh about 90 KG. If I go up 8 meters on a few flights of stairs - basic physics says that Mass x Accel. of Gravity x Height = the potential energy created in lifting that object to that height. In that example, 90 KG * 9.8 m/s2 * 8 meters = 7,056 joules, or about 1.7 kCals. So, am I burning exactly that amount in walking up those stairs? Or is there something else going into that equation? Is my body that efficient? Is 100% of the energy that my body creates in going up those stairs created by the food that I've eaten, or does something else (like the oxygen I'm breathing) play a part? Thanks! [link] [comments]  |

| Are there different nerves for pain than for other senses and motor activities? Posted: 05 Jun 2016 12:21 AM PDT I am confused about why pain killers only deaden pain and don't e.g. make your arm numb or make it impossible to move it. Are there two (or more) independent sets of nerves? Like one for pain and others for the other senses and motor activity? Or is there only really one nervous network and pain killers just somehow affect its activity? Or does no one really know? [link] [comments]  |
| Posted: 04 Jun 2016 09:52 PM PDT For example: we have the decomposition of hydrogen peroxide (H2O2) into hydrogen (H2) and oxygen (O2). This happens in the presence of a potassium permanganate catalyst. Why is the potassium needed? How can it be part of the reaction if it is not a part of the product or reactant? What does it do to cause the reaction? [link] [comments]  |

| Posted: 04 Jun 2016 09:10 PM PDT In the human genome only 1.1% of the genome is spanned by exons, whereas 24% is in introns, with 75% of the genome being intergenic DNA. How was this discovered? How exactly did we find the exact regions for exons? [link] [comments]  |
