What on earth is a Neorotransmitter? i saw it on the polls so i don't really know where this question belongs (!!!)

What exactly is the immue system? I have heard people telling other ti boost their immune system. where is our immune system located? How to boost the Immune system? By eating only Vit. C stuff? ah and i think excercise too. My biology classes didn't cover immune system but they taught what are white blood cells and stuff.

I do not speak English but I'll try to do my best. In school I have to support or refute the following proposition: "There must be more students in science and maths if we want to prevent that the technological progress in the western world comes to a stop." What do you think about this? I hope it will be an interesting discussion with pro and contra arguments. Thanks!

What is the voltage required for the effect to be produced ? I would like to know the lowest possible voltage that would need to be supplied. Thanks in advance.

Ok. I don't want anyone beating me up for this. But here something that i was thinking about. How know when u have cotton clothes. Lets say red in colour. Why is it when water is dropped onto it, it goes darker. Any colour in this case. Even though water is transparent. I have an idea, but I'm not giving it out. Just so that i don't influence any other ideas!!! Thanx

Is it frightening to anyone else how similar our world is to Farenheit 451? Not in all actual manifestations, but in mentality, we're goin down that road. What i think the problem is stupid people getting in power. Stupid people in media and buisness feeding us crap, as said in farenheit 451 : man not born equal, but made equal. Society is covered in so many freakin rules and unquestioned mentalities of stupidity, all these things are programming us not to be self thinking individuals. I think the concept of Farenheit 451 goes deeper when combined with the Matrix. I heard that matrix is a remake of some other movies about reality, i haven't seen them, so I chose the …

Just started a new group: http://groups.yahoo.com/group/scmcourseworkhelp Its for coursework help on chem bio physics and math, would be grateful of any contributions (coursework on any of these subjects). Thank you

Sorry about the downtime last night. As a result, the server time was several hours ahead of the actual time. The time was just reset to the accurate time. Thus, all new posts will not show up at the end of the thread until the time is LATER than the last post in the thread. Everything should be correct as of 6pm eastern time tonight. Again, sorry about the inconvenience. We're working on a dedicated server right now.

About the movie 2001 Space Odyssey, in the other post, I think The Matrix is much more important reference movie that will reshape our future. Check, for instance, this link about the Philosophy of the Matrix

I just watched this movie yesterday in its entirety for the first time in a very long while. I enjoyed very much, even though my brother thought it was monotonous, boring, and pointless. What do you all think about the movie?

I was just wondering how an LCD display worked. I heard that they like water bubles and they pass certain ammounts of electricity through them to make them display the right color. I am not sure if all/some of that is correct.

Well, up here in CT were are into our second major snowstorm and I was just wondering why snow sticks to vertical objects such as windshields, windows, walls, etc. Could it be that the snow melts and frezes to the suface or something?

It’s a small world” is such a casual saying, but ever thought what it actually means? The theory of “six degrees of separation" claims that any one of us can be linked to any one else on earth by a chain of six contacts on average. It’s a fascinating research area, especially when harnessing email and the Internet. I am hoping that the Scienceforum community could help me with a small experiment in this area, toward my university final project in web media design, the small-world-network , http://www.small-world-network.com . It’s short, confidential, won’t lead to spam (promise!), and will help further research in a field championed by Stanley Milgram and, more rec…

What measures could a person take to reduce the risk of bacteria infection and the development of bacterial disease? What happens after bacteria has gained entry?

I have read in a book of facts. That the fourth state of matter is plasma. But what actually is plasma? I need some enlightenment. And one more question. What is water retention?

i asked when you think the moon stopped spinning. well i think it was 65 million years ago.

It is the rainy season in Singaopre now. This question crossed my mind as i was sitting on a bus. It was raining outside and i was looking out of the window. I realise that water droplets tends to stick on the glass surface. Instead of falling down and off the glass surface due to gravity, it did not. I find this really surprising. And after that, i read a book "The stuff of life" describing water and its properties and stuff. Two words caught my attention, "surface tension". I was wondering has it anything got to do with that. Need someone to enlighten me. Thanks.

Hey, sorry if this is a repeat, but can you guys reccomend a cood science fair project for me to do? I want it to be something good, but nothing that requires materials or something that would be hard to get. Thanks!

Aoccdrnig to a rscheearch at Cmabrigde Uinervtisy, it deosn't mttaer in waht oredr the ltteers in a wrod are, the olny iprmoetnt tihng is taht the frist and lsat ltteer be at the rghit pclae. The rset can be a total mses and you can sitll raed it wouthit porbelm. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a wlohe. I find this very interesting? Has anyone else here done controlled experiments with this?

hey what i'm new and i have a question, convection currents happen in the asthenosphere and are powered by nuclear decay right? at least thats what my science text book said about convection currents, but there is no nuclear elements inside the earth so how nuclear decay powers convections currents with out having a nuclear element to irradiate nuclear decay?

It is sometimes funny! I get goosebumps out of a sudden. And i can make goosebumps as and when i want. Is it natural? What causes these goosebumps?

I was reading my shaving cream label and it contains stuff i never knew i put on my face. Such as Propane and Butane. Why does it contain these things? and what are the long term effects on my skin?

Well, i'm feeling really tired. For consecutive days i've been sleeping rather later. I only tuck into bed at 1am. So, i always find myself very easily tired. Not only that i realised that my lips are very pale (grey in colour) and my eyelids are very light pink. My finger nails are also very light pink. I don't really know why. Is it possible to do with me not sleeping early? or my diet? Or what? Sometimes, i have some difficulty breathing... but it is not that serious. It is more like i'm not breathing enough oxygen.

here`s a pic I took of an ordinary Domestic house spider, except it`s much bigger than I`ve seen before, any Idea what type it is and why it`s so big? http://www.yt2095.net/experiments/spider1.JPG this thread isn`t a competition by the way, and I know there`s much bigger creatures out there in different countries and pets etc... but this one`s totaly "wild", I`de love to know what sort it is though. any clues?
