I was wondering; Is it possible to grow tall even if your parents arent tall? Im 5'7 and would like to grow another 2 inches. I've been taking suppliments like zinc and calcium to assist in growth. Is there anything else I could do or am I wasting my time?

hi, is there a maximum the brain can remember in terms of knowledge?

Before I start, I must warn you I am a chemist/physicist not a biologist. However, this problem has been in my mind for some time and I want to know if anyone can help. I have heard that our perception of time changes with temperature. If I recall correctly, in the cold time seems to pass slower and in the heat in seems to pass faster. During a recent ski holiday, whilst using the sauna facilities, I played some music through the speakers, I couldn't help but notice the beat of the music was slower. Infact it seemed significantly slower. This was at the point where I was about to leave because I was feeling so overheated and exhausted, I stopped as long as I could…

What's the easiest/best ways to describe the differences between: Somatic and autonomic nervous system -somatic has the motor neurone's cell body inside the CNS, while autonomic has its motor neurone's cell body outside the CNS, in the ganglia (2 neurones carry impulse from CNS to organ) Sympathetic and parasympathetic NS. -Sympathetic is concerned with 'flight or fight'; parasympathetic is 'rest and digest'. -In sympathetic NS, ganglia are connected to each other? (not sure about that) -Parasympathetic NS - synapse between preganglionic neurone and autonomic neurone is inside the organ (while sympathetic is in the ganglia close to spinal cord). -Parasympa…

So a friend of mine has a wack idea about drugs and how they work. So, I have a few questions. First, just how far can the brain go in preventing drugs from working? And creating the effects of drugs on their own? I'm talking any sort of drug, from caffine to morphine to marijunana to heorin. Can anyone give me a semi-detailed version of how drugs work on the brain and body. I know that most (all?) get into your blood and effect your nerves and brain by blocking specific types of transfer but I need the fancy names and a better idea of how exactly it all works and how differnt drugs can work differntly and the like. Semi-technical, maybe slightly above what m…

A stomach cell dies after 2 days, will this short life span, mean that even in our own life span our stomache cells will evolute to become stronger?

I was watching a show on the science channel about a man who had a whole bunch of electromagnets and tesla coild, so the whole room was full of electromagnetism. When he pointed a really strong tesla coil, which produces alot of electromagnetism, or maybe it was an electromagnet, but anyway, the electromagnetism was so strong that objects would move, float, and shatter that weren't even metal (there were video clips of this, and it was real). But the strange thing was that when he left the room, the objects stoped moving, and when he came back, they started to float around again. The show also showed a robot (different person now) that moved randomly to move a bead from o…

I read an article (can be found here ) that said that a japanese corporation was able to achieve 'ultimate force feedback' by altering the sense of balance using small electrical currents and a clip on electrode. I have always wanted to integrate our body into the entertainment and games we play. I was wondering if anyone has an idea of how this would be achieved? I am a good electrician and programmer myself (although I am turning 15 in 2 days), and I have even build my own robot (not one of those rinkydink "build it yourself" kits, but I actually went down to a surplus store and bought all the IC's and stuff, soldered them on to a component board, and built myself a…

I was thinking the other day about an instance which occured when I was in grade school. Our third grade class had a sewing project for which the entire class was expected to participate in. My sewing partner knelt down upon a needle which was sticking up out of the carpet. I watched as the needle penetrated into the girls kneecap. However, the girl remained oblivious to the presence of the needle and continued with her work. Nevertheless, I felt the need to notify her of the impaled object and as soon as she noticed it, she began to scream hyterically from the pain. Clearly from my understanding of the central nervous system, there would be nerves located within the vici…

I've been going to bed and getting up at the same time, but recently I am much more tired throughout the day. Sometimes I come home and take naps, which I never used to do. It also seems like I am dreaming more (or I am remembering them better I guess). They are a lot more vivid and kind of "hang around." Do you guys have any idea what may have caused this change? I'm not on any medications and I don't think I'm really stressed or depressed. Maybe you know a way to make sleep more restful? If this is in the wrong forum, then I apologize and a mod can move it at will; i'll find it.

I've never personally gone into the desert, but I'd like to live in a desert climate some day. What kinds of things should I do now if I want to live in a desert? I've gotten some pretty good tips from my friend who's survived off the land in desert climate. Anyone know out of the ordinary things I should be doing to ensure my survival? Should I learn how to live off of meager rations of food and water for 2 weeks or something?

What part of the brain is used when we want (are trying) to remember something? I know stimulus can cause us to remember somthing, but how do we think about remembering?

Hi, This will probably seem a bizarre question, in which case I apologise! I am considering writing a book set in a dystopian near-future, the plot of which will rely on the ability of certain individuals to control the behaviour of their 'subjects'. One idea I have considered involves the use of subcutaenous implants capable of temporarily crippling the 'wearer' with an electric shock on receipt of a remote signal. The intention would be to cause such excruciating pain as to make it almost impossible for most wearers to even contemplate disobedience, but for the shock to be non-lethal and any resulting paralysis only very temporary. It would of course be possib…

Anyway (using home equipment) of trying to work out what blood type you are? And why do people have different blood types?

http://www.sciam.com/print_version.cfm?articleID=000B077E-AD46-1047-AD4683414B7F0000 I had the impression that this statement about using 10% of our brain involved our ability to use only 10% of our brain at any one time. So if that was the case, this article would not be rebutting such a interpretation. Recently I remember an article showing that kids known as "child genuises" have been shown to use more of their brain when figuring out problems. Is this what causes people to be smarter ? If we can use more than the supposed 10% of our brain at once, I suppose it would make problem solving a lot easier. Or would it ?

Sorry about the vagueness of the thread title, But Ive got an ongoing disagreement with a friend that I need settled. I cant find one dang thing on the web concerning it, Except a brief mention in a university study. It was both vague and ambiguous. Do people of African descent, Blacks, Have an extra tendon in their leg? My friend seems to think so. I emphatically say NO!! Ive read about some people having more developed muscles or parts of their body than others, But for one race to have an altogether extra muscle is silly, to me. IF you know of any links that address this matter, Could you please post them so I can end this pointless debate with my friend? Thanx

this is a question posed by my wife the other night, one I could not give an informed answer to. Why is it, that when you`re really tired and you Yawn, you get tears in your eyes? I made a thread a while ago: http://www.scienceforums.net/forums/showthread.php?t=5530 about the contagious factor of Yawning, and was hoping for a better input with regards to it`s possible social implications on an evolutionary scale. but tears??? I`m guessing it`s an "Auto-Clean" routine that happens while we sleep, aided by REM sleep? that`s the best answer I could give / Guess at. I/We would be gratefull for any True / Informed answer Cheerz

i'm doing some physical training with a friend, and he said ballistic stretches are under debate as to whether they are good or bad for you. i had heard a couple years ago that ballistic stretches are bad for you as initial stretches, but good for you after a work out. for those that don't know, ballistic stretches are when you stretch a muscle in a burst, like bouncing when touching your toes, or doing front kicks in a quick swings. so does anyone know the most recent opinion, or does anyone have a good idea of the truth?

My cousin had a child today. The same two fingers are fused together on both hands and the corresponding toes of both feet. He also has a very high fever and is not considered in stable condition. I don't have any more info since they live far away and my uncle was frantic when we talked to him. Last I heard they were running some tests on the chromosomes. Is this a known disorder or some kind of strange mutation? Do you have any idea what it could mean for the child's health in the future, or other problems that may exist that we don't know about yet?

Firstly my neck. If i look up and 45* to the left the left of my neck hurts, like where a muscle might be compressed (that area). Secondly foot. I have a severe pain in the back of my foot (below achillies tendon) like a trapped nerve or something. I havent reasently banged it, it just hurts. I know it would be better if i saw a doctor, but it might provide more interest here.

This is a bit difficult to describe but anyway. When Im relaxed, e.g. quitely typing, along with somebody else doing something , as well as perfect silence (other than a person quietly speaking/ doing something), I sometimes get this sensation in the back of my head. Now its only when im relaxed, and sitting quietly with few others around, But its REALLY nice, i cant really force it to happen, it just does. Anybody know why this happens, or anybody get the same sensation? I get it probably around twice a month.

What would happen if you wore a cap with magnets underneath for a long time? Would the iron in your blood be attracted to the magnet? What would happen if you had a lot of iron in your head? What else might the magnet attract? What are the effects of those things?

so i cant find shit about the effects of different wavelenghts (event within the visiual wavelenghts) that will cause different signaling responces, it seem that when light stimulates a photopigment cell it will cleave or cause a cis trans conformational change that allows farther reactions to cause a perceived responce.....seemingly if these was the case for different wavelenghts then the changing of wavelenghts due to color would only befound in cones(color sensitive) but not in the the rodes......my question is what is the diffent signaling responces to the differnt color wavelenghts, is it just a cell stimuls difference(be different cell react to different wavelenghts…

Hey, I have a big anatomy project, and was hoping someone would be willing to try and help me. It's kind of long, so I don't want to post it... but if you'd like to help, PM me? Thanks.
