  1. I don't think so, although I believe some are sensitive to magnetic fields. I may be wrong.
  2. Sounds like you may have mild synesthesia, which is neither a disease nor a defect, just a rare condition. It affects (I think) around one in 500,000.
  3. I was bitten by that bastard horse. Odder, but equally true.
  4. I'll go for that one! It's not particularly likely, but it sounds nice and peaceful.
  5. Er...ok? Did you accidentally post your orthopaedic notes, or is there an actual point to this?
  6. Hemp plants (and relatives) are annuals. As such, they don't really like their roots being messed with once they've put out their second set of leaves. Perennials are more robust. However, consider the situation. The temperature in direct sunlight on the inside of a window is going to be a lot higher than in direct sun outside. Plus, there will be minimal air movement, and probably a lot lower humidity. In order to thrive, plant of that family like free-draining, poor(ish) soils. They like direct sun, but also moving air. My advice; make sure the soil is free draining. Don't water too much (wait until the soil has started to dry out before watering. Aim to keep the soil damp, not wet). Don't feed it too much. If you are using a chemical fertilizer, you could dilute it to half the recommended strength. Put the plant outdoors. If it's not already dead, it should pick up after 5-7 days outside, in a spot that recieves plenty of light, but is sheltered from wind.
  7. You are in no other danger, but compressing your spinal cord is dodgey enough to be going on with. If you stop doing it, you should be fine. Come to that, if you keep doing it, you may be fine. I wouldn't advise it though. Like breaking any habit, the first step is to make yourself aware of when you are doing it. To do this, you might want to adopt strategies like recruiting friends, colleagues and family to point out to you when you are doing it. Or you could wear shirts with collars, so the collar digs you when you begin to flex your neck. Anything like that will bring the act to your attention and let you realise how much you do it without thinking. Once you are aware of it, you can stop it easily enough.
  8. Tingling (parasthesia) is a sign of some kind of nerve trauma/ischemia. A temporary tingling shock is usually due to sudden compression (like hitting your funny bone, which is sudden compression of the ulnar nerve). If you cracked your neck and felt a sudden tingling shock in all your limbs, then it's likely you applied some degree of compression to your spinal cord. If your neck cracking is extreme enough to do this, my advice is that you stop doing it.
  9. Well, that doesn't really go very far in establishing the existence of psychic connections, does it?
  10. I still think Navajoeverclear's biology teacher either: was misquoted, or phrased the statement extremely badly. I think would have been better put as "A possible explanation for the hypothetical existence of psychic connections may be that....one brain picks up on the electrical and magnetic fields of another. ". The phrase "psychic connections can be explained by..." includes the inherent assumption that psychic connections exist and that their existence has been established.
  11. And yet it is affected by gravity and can be bent by stars and pulled into black holes?
  12. In light of the above, surely the same disclaimer should be printed in the bible and any other religious texts presenting alternative explanations for the origin of life? In which case, the statement: is fundamentally flawed, because children cannot know they were created by a God, because it is a theory, and not a fact. According to the tripartite (JTB) theory of knowledge, knowledge = Justified True Belief. In order to know something, a) we must believe it, b) it must be true, and c) we must have justification for believing it. Whilst evidence is justification, evidence alone does not make a thing true, therefore, without proof positive, we cannot know how life originated either way, we must decide what to believe based on our own evaluation of the justification (evidence) for believing it. Therefore, if such disclaimers as must appear in science texts through legislation, then it seems reasonable to demand that disclaimers such as "genesis is a controversial story which does not constitute a theory, yet which is presented as an explanation of the origin of living things" and "...the unproven belief that an invisible, omniscient and omnipotent being produced a world of living things." appear in all religious texts presenting a view on the origins of life. If this does not happen, then there is a clear bias both in the legislation and, perhaps worse, in the information with which American students are to be presented. Legislators should note: Passing a law on something does not influence its veracity. I.e. stating the bleedin' obvious (that evolution is a theory) does not make it any more or less true or false, nor does it affect in any way, the validity any evidence that exists for it.
  13. True. When you metabolise fat' date=' the byproducts are carbon dioxide and water. When you breathe out, you expel C02 (the byproduct of fat, not fat itself) and when you urinate you lose water (again, a byproduct of fat). There should be no fat in your stool. If there is, you have a problem with your gall bladder or bile duct. All organs need water to work, but you kidneys require blood-pressure and blood solutes levels to be within certain limits in order to function normally. The liver does break down food to any great extent. It acts as a kind of factory, processing sugars, converting them and storing them in the form of glucogon. Your kidneys are filters only. That's all they do. They need a certain blood pressure to push the filtrates and water through permiable capillary walls in the glomeruli (Bowman's capsules), and they use an osmotic gradient in the loops of Henle to reclaim the water and concentrate the waste products. Increasing the amount of water you drink will reduce the osmotic gradient in the loops of Henle so you lose more water (your urine becomes more dilute). Reducing your water intake increases the osmotic gradient and result in more concentrated urine. As you ahve already stated, water is one of the byproducts of fat metabolism and it is excreted through the kidneys as normal. Unlike with food, the body does not have a 'predictive' system for water; it is too critical. With food, if you fast, the body goes into 'fasting mode' and trais to reduce your energy output as far as possible (which is why slimming diets based on fasting are counter-productive). With water however, the levels are more critical and the margins for error are a lot smaller. When you dehydrate, the osmotic gradient increases and your kidneys reclaim more, but this is a passive function of dehydration, not a predictive physiological strategy. There are mechanisms the body employs to conserve water, but these are short-term compared to the bodies strategy for dealing with fasting. Dehydration will always kill before starvation. The mail fuel for the body is carbohydrate (complex sugars, usually broken down to simple glucose for use). Fat constitutes a rich, but acute source of energy, which is why we store energy in that form. Unit for unit, fat (triglycerides) contains about 2.5 times the amount of energy as sugar, but it takes more to break it down into a usable form. There are also some nasty byproducts of fat metabolism (ketones). If we are forced to break down body fat for energy, one of the side effects an increase in ketone levels; i.e. the individual becomes ketotic and begins to poison themselves. I don't know enough about the Atkins diet to comment on it. But, by own feeling (in the absence of further information) is that a balanced diet, providing for all the body's needs, combined with regular exercise is better than forcing the body to work harder to compensate for an imbalanced diet in order to lose weight.
  14. Yep, and to make it even more efficient, birds have a counter flow system where deoxygenated blood and fresh air run in opposite directions, ensuring the blood is absolutely saturated with oxygen by the time it leaves the lungs. Very efficient system.
  15. That's a bit like a bomb disposal engineer saying "I'll put me tin hat on if it stars exploding"
  16. Can't really help without further information: What plant are you trying to grow? Where are you trying to grow it (indoors or out?) What soil was it in? What soil did you pot it into? What feed are you using?
  17. Try this: http://www.math.toronto.edu/mathnet/questionCorner/geomean.html It may be of some help.

    Rat Vs. Human

    Yes. The rat has a further advantage of being closer to the ground and having a very sensitive sense of smell. As the rat runs the maze, it makes errors. However it has the advantage of being able to smell where it has been before, so never makes the same mistake twice on the first run of a maze. Threfore, rats are faster than people on solving mazes on the first run, and better at 'mapping' the maze than people so it takes fewer attempts to achieve flawless runs.
  19. Yep, that's right. One form of breathing is dependent on the intercostals lifting the rib cage. The other is dependent upon the abdominals lowering the diaphragm.
