Do people who eat fewer calories live longer? Posted: 17 Sep 2016 02:52 PM PDT I swear I remember reading somewhere that people who are fewer calories tended to have longer lifespans, and for that reason I've tried to eat a little less (not going for a second serving, etc.). Obviously people who are overweight are less healthy than people of average weight, but does the trend continue in the opposite direction, with people who are lighter than average or eat slightly less than average living longer? Recently I thought about it and realized I don't have any idea where the original idea/assumption came from. Is there any basis in science? submitted by /u/yaminokaabii [link] [comments]

Why do matter and anti-matter annihilate each other when coming into contact? Posted: 17 Sep 2016 12:04 PM PDT I was thinking about how a neutron can decay into a proton and electron (plus something else, I think?) - two particles of opposite charge. So how come an electron and an anti-electron (positron?) wouldn't somehow combine into some neutral particle rather than self annihilate and convert their energy to photons? submitted by /u/dougman82 [link] [comments]

What happened to Olestra? Posted: 17 Sep 2016 03:38 PM PDT I understand that it caused negative gastrointestinal effects but can someone explain the science behind it? Is it still legal in North America? submitted by /u/PotMeister [link] [comments]

(Biology) How would you die from cancer as opposed to chemo? Posted: 17 Sep 2016 02:28 PM PDT Maybe I shouldn't be asking this here but how do you die of cancer/what does it feel like opposed to chemo ? So I know how cancer is caused, what it does and how it spreads through the body, but since everyone gets chemo which kills the cells (hopefully the cancerous ones first) a lot of times the body doesn't recover after the cancer is gone because the radiation kills them. Obviously I'm not talking about successful cases of remission, purely cases of death, I want to know the difference biologically and 'how it feels' between dying of chemo but mostly cancer free and dying of cancer having chose no forms of medication. Edit - ahh right thanks guys, this was really informative. So it doesn't really kill you itself, but by (putting it basically) shutting down the systems it's located in (can also cause wasting, explained by /u/iayork ), I know it's not the be all and end all though as it can spread to the lymphnodes. Also /u/Kurgon999 yes I did actually think chemo was directed radiation so no problem, it's not a laser and doesn't cut you so I didn't give it much thought but it seems I was wrong. submitted by /u/The_Meatyboosh [link] [comments]

Are O(2^n) and 2^O(n) the same classes? Posted: 17 Sep 2016 03:27 PM PDT In computer science and math, in order to describe functions bounded from above from the function 2n, some authors use the first notation, some others use the latter. Is there a difference between these class of functions? submitted by /u/a-lumen [link] [comments]

Would reducing the frame rate of the part of a computer screen that's inert while increasing the part of the screen that's active save power? Posted: 17 Sep 2016 03:20 PM PDT From what I understand, GPUs save power by reducing the frame rate of a screen when there is less motion on the screen. But they do this for the entire screen at once. Would a GPU that only reduces the frame rate of part of the screen he efficient? Would it even be possible or would you need a separate controller for each pixel? submitted by /u/lookmanofilter [link] [comments]

Are alpha particles in and of themselves radioactive? Posted: 17 Sep 2016 12:17 PM PDT That is to say, if an alpha particle has already been ejected from the parent isotope, is that particle itself radioactive? If it is, does it have a half life? I think I answered my question already by googling He-4, which is stable. So it's just the speed of the particle and lack of electrons that causes the ionization, right? submitted by /u/shitheadsean2 [link] [comments]

Do black holes accelerate matter to light speed? Posted: 17 Sep 2016 01:58 PM PDT Does matter ever become gravitationally accelerated to c? submitted by /u/bilabrin [link] [comments]

Why is diffusion of hard spheres not affected by the density of the spheres? Posted: 17 Sep 2016 08:52 AM PDT I know that: frictional coefficient = 6*pi*viscosity*Stokes radius and that frictional coefficient is inversely proportional to diffusion coefficient. Stokes radius is the radius of the sphere (as the sphere is hard). Molar flux is the product of the diffusion coefficient and the concentration gradient, so it is the radius of the sphere that is related to it's diffusion, not the mass (as density & mass don't come into any of the equations). But if I think intuitively, the spheres are being bombarded by other particles as they move through the medium. If a sphere is more dense, the bombardments would transfer the same momentum but less speed, and the sphere would move more slowly. If a particle is slowly wiggling through solution, a heavier particle would have smaller 'wiggles' and move more slowly. I have to be wrong somewhere, but where? submitted by /u/994phij [link] [comments]

[Biology] There's a dinosaur called Carnotosaurus, whose arms end after the elbow, what are the benefits of this? Posted: 17 Sep 2016 01:31 PM PDT Also, why does it even have arms, do those "stumps" serve a purpose, are they for balance? Is this the case of a mutation and not really just natural selection? Why do we not see more animals with this feature? submitted by /u/Tsunami6866 [link] [comments]

How do you calculate displacement, velocity, and proper time of an object undergoing constant proper acceleration, starting from non-zero, non-collinear velocity with respect to an observer? Posted: 17 Sep 2016 03:36 PM PDT Using the Relativistic Rocket equations, the displacement d, velocity v, and proper time T of an object undergoing proper acceleration a from rest for a given coordinate duration t can be calculated with: d = (c2 /a) (sqrt[ 1 + (at/c)2 ] − 1) v = at / sqrt[ 1 + (at/c)2 ] T = (c/a) ch−1 [ad/c2 + 1] Imagine an object starts with initial relativistic velocity v0, and accelerates with proper acceleration a at some non-zero angle θ from v0. How would I calculate the object's displacement, velocity, and proper time after a given coordinate duration? submitted by /u/taylorules [link] [comments]

How does T-cell know when to stop its immune response? Posted: 17 Sep 2016 04:27 AM PDT I mean, TCR has ITAM domains and inhibitory receptors have ITIM domains. Their both ligands are on APCs (I suppose). If a t cell recognizes a non-self antigen, it will receive both inhibitory and activatory signals. 1) How does t cell know what to do (there is a perfect balance between stimolatory and inhibitory signals)? 2) When t cell begins an immune response, how does it know when to stop this response, in order to not damage your organism? submitted by /u/Biasy [link] [comments]

Do bioluminescent/biofluorescent organisms use sunlight to recharge, or is it primarily an enzyme based reaction? Posted: 17 Sep 2016 06:17 AM PDT The main reason I'm asking this is because on my campus there is a river with these luminescent jellyfish, however I have noticed that they don't light up in the day or on nights where the moon-light is especially bright. There are also what appear to be thousands of luminescent plankton in the river, and during these times they too do not light up. submitted by /u/TheDesertSnowman [link] [comments]

At what size does a wire mesh stop acting as a Faraday cage? Posted: 16 Sep 2016 06:27 PM PDT Wire meshes can often be used as Faraday cages to shield the inside from exterior electromagnetic waves. At some point, the mesh should stop being a Faraday cage if the holes keep getting bigger.

what is the definition of the word "cold" in deep space? Posted: 16 Sep 2016 06:30 PM PDT if cold is the slowing of the vibration of atoms and there are only sparse atoms in some areas of space, how is "cold" expressed where there are so few atoms? submitted by /u/TheQuips [link] [comments]

Is there a way to determine the direction of gravitational pull on the surface of an irregular object? Posted: 17 Sep 2016 07:08 AM PDT Let's say we had a 1000km-thick cereal bowl floating in space. If I started pouring milk onto/into this bowl at any given point (so, not necessarily into the bowl - perhaps on the outer side or bottom), would we be able to determine where the milk would flow? If so, how? My understanding of gravity starts and stops at spherical objects, which is why I'm curious. If we wanted to land a probe on an asteroid shaped like, say, a cereal bowl or a donut, how would we know the best spot to land? submitted by /u/dobu [link] [comments]

Is there such a thing as a core of a star? Posted: 16 Sep 2016 03:44 PM PDT I know hydrogen becomes iron, but does that iron amass in the center of the star to eventually cause the star to fail, either in nova or in red dwarf? submitted by /u/rugbyrun [link] [comments]

How would Nuclear Propulsion work? Posted: 16 Sep 2016 03:58 PM PDT I want to know how it would work. But most of all, how it could successfully be done without damaging the ship. Also would it be in space or on the ground? submitted by /u/ArmoredBattalion [link] [comments]

Could Mars have had a rich, earth-like flora even when we now can't see any hint of it? Posted: 16 Sep 2016 01:21 PM PDT When we talk about life on Mars we usually talk about microbes or other simple and small life forms. I wonder if there could once have been plant life, forests with huge trees without seeing any evidence today. Like, could they have been completey destroyed after Mars lost its atmosphere? So that not a single tree trunk or something like that survived (as a fossil) ouf of billions of trees all around the planet? Because all we see on pictures from our satellites and rovers today is basically wasteland. Or is the lack of any evidence today a strong hint that if there ever was life on mars, it never was much more developed than microbes. submitted by /u/linknewtab [link] [comments]

What is going on in your body when it starts to hurt after resting on a hard surface for a long time? Posted: 16 Sep 2016 01:20 PM PDT I have been transitioning to sleeping on the floor this past week and although it is not at all necessary to exclude a folded towel beneath my head I would really prefer not to have to do that. Problem is, as you might expect, trying to fall asleep with your head resting on a hard carpeted floor for thirty minutes results in a progressively more irritating pain at the point of contact the longer I refuse to lift it up. What is going on at that part of my head that causes it to hurt that way? Are there going to be any significant consequences to ignoring it? A callus? Reduced blood-flow to my brain while I sleep? I don't really know, so I'm asking science. submitted by /u/SixtyNinePlatypi [link] [comments]

What is implicit egotism and how much does it really affect our lives? Posted: 16 Sep 2016 04:22 PM PDT I read this article today about how people are drawn to things that are similar to their name.

Are there any known weaknesses in the Nielsen Ratings? Posted: 16 Sep 2016 03:19 PM PDT From what I understand they sample cities around the country and estimate viewing based on those samples. Are there any biases or things unconsidered by this method of data collection? I was also curious if perhaps somebody cross referenced data from Netflix viewings. I'm guessing Netflix uses more direct data (i.e. simply how many people streamed this show or movie) and maybe you could compare patterns in viewing of shows or genres by this precise data set and see if there are any interesting discrepancies between the two. The second part makes this a loaded question, but answers on either or would be great! submitted by /u/acollich [link] [comments]

Do painkillers affect more than just perception of pain? Posted: 15 Sep 2016 10:42 PM PDT Do painkillers have other effects on the body, other than just blocking the perception of pain? And does blocking pain cause other changes in the nervous system and body? Today at work I experienced a bad headache. For several hours, I felt tired and slow, and unable to think clearly. My mood was terrible. I took paracetamol at midday, and within an hour my headache had lessened, but the thing I noticed most was that I felt alert and refreshed, like I had just woken up. I could think clearly again, and my mood was much better. My understanding of painkillers was that they simply blocked the pain, without really changing anything else. I suppose I am asking: is perception of pain linked to decreased cognition? Or does something else happen that improves cognition while also reducing perception of pain when painkillers are used? submitted by /u/Noh_weigh [link] [comments]

How does an encryption system share keys with the intended recipient without letting a third party obtain the key as well? Posted: 15 Sep 2016 08:45 PM PDT I understand that encryption works by providing two parties a key that decodes messages or data they exchange. What I don't understand is how this protects information from a third party that has tapped into one of the parties at the beginning of the communication. For instance, let's say someone has hacked my wifi and watches me log onto Gmail. When I log onto Gmail, don't I get the encryption key at that moment? Wouldn't the third party also have the key and have the ability to read my messages? Can't your ISP do the same? submitted by /u/xarici [link] [comments]

If a sphere is rotating, is it moving relative to itself? Posted: 15 Sep 2016 04:56 PM PDT I had a debate with a co-worker in which he said that an object can move relative to itself. That an object can be its own frame of reference. We were talking about the Sun as it moves through the galaxy. We of course went through the obligatory acknowledgement that the galaxy itself is moving through the universe and so on. However when I said that even the sun's rotation could only be described as it related to other objects, he disagreed and said that an object could be moving relative to itself. I proposed a thought experiment in which a basketball was the only object in the universe. I said that, in this scenario, you couldn't say that the basketball was rotating relative to itself. You couldn't say that the basketball was rotating at all, because it would have to rotate relative to something else. He disagreed and said that in this scenario the basketball could be said to be rotating because it could rotate relative to itself. So we're not talking about position or velocity here, but simply rotation. Can something be said to be rotating relative to itself? submitted by /u/DrSheldonC00per [link] [comments]

This lightning storm over Reading UK has been going on for about 12 hours now - how is it still going? Shouldn't all the air be de-ionized by now? Posted: 15 Sep 2016 09:24 PM PDT I love watching storms when they happen, but this one has been going on since just past 5 p.m. this afternoon, and it's now 5 a.m. I've never seen a storm last this long, and when I did a search, other sites seemed to back up the idea that a storm only lasts about 30-60 minutes. I don't think it's a single storm - one moved across almost overhead at about 6pm, but it's otherwise been quite distant until 3 a.m., and just now - I've seen flashes of lightning almost constantly, but a lot of them have been a few miles away with a 10-30 second flash/rumble difference. Even so, I thought that unless the wind was powerful enough to create its own lightning (e.g. with a tornado or hurricane), it took days of muggy/humid weather to build up enough ionized air for a thunderstorm. It has been very muggy in the past week, with record high September temperatures, but surely the air was de-ionized the first time around - how is there still enough energy in the air for so much lightning? submitted by /u/Patrik333 [link] [comments]

Is there an upper limit on how large a solid object that is one cohesive unit can be? Posted: 16 Sep 2016 05:08 AM PDT I was reading about the Pillars of Creation earlier, those are gas/dust clouds, but it made me wonder if there was an upper limit for a solid object. By solid I mean one cohesive unit that can transmit a vibration or wave all the way through it in the vacuum of space, though I'm also curious if there is an upper limit on an object where all the molecules are bound together into one cohesive solid unit.

Do some people have a chemical need for SSRIs? Posted: 15 Sep 2016 01:23 PM PDT Hi Ask Science, I have a of couple questions on the chemical/ biological need for SSRIs. 1) Do some people naturally produce less serotonin in their brains, meaning they have a chemical need for SSRIs to have the same amount of serotonin in their brain as the average person? 2) Does prolonged use of SSRIs change the chemical/ biological make up of the brain? For example, originally person x produces serotonin at a rate of 10, they take SSRIs for 10+ years and their brain gets use to that absorption rate of serotonin, so takes production rate down to 5. Meaning that person x now has a chemical dependency on SSRIs to have an average level of serotonin in their brain. Researching the topic I found an article 'The mechanisms of tolerance in antidepressant action' (2011) - Giovanni A. Fava, which delves into the topic of long term use of SSRIs, concluding 'appraisal and testing of the oppositional model of tolerance may yield important insights as to long-term treatment'. If any of these questions need more clarification please just say. If anyone has any related questions just post them in the comments and we can try and find out the answers! :) submitted by /u/Redskyeatnight [link] [comments]

I've seen some explanations and theories, but am stumped as to why this mesa has such a curvature. Also, what gives a mesa/plateau/butte etc it's flat top?

What genetic diseases only affect a small percentage of cells in the body? Posted: 15 Sep 2016 08:45 PM PDT Hi Reddit, I realize that this may sound like a silly question as all cells in the body contain the same genetic make up. But are there any known diseases that only affect a small percentage of the total cells in the body? I'm only wondering because of potential applications for sparse gene delivery in the context of gene therapy. Thank you. submitted by /u/KChan85 [link] [comments]

What would happen if you made a cube mirrored on the outside? Posted: 15 Sep 2016 10:26 PM PDT Say you had a cube that was made of 100% reflective material on the outside. If you were inside this (large enough) how cold/hot would it be? Would it still heat up even if no light passed through it? submitted by /u/NUMBER7777777 [link] [comments]
