There are many articles on PubMed in regard to what is termed Vibroacoustic Disease. The majority of human studies appear to center around aerospace workers and long term exposure to LFN (low frequency noise). Is this phenomena recognized as valid in the scientific community, or is the jury...

I don't subscribe to believeing the chemtrail conspiracy (as its based on a false premise that all contrails should instantly dissipate), but the other day i was walking home when it started raining and my arms started itching, i looked at them and they were covered in red blobs and rashes. I...

I was wondering if anyone knew anything about epidemic models which take into account the ability of a disease to mutate. Basically I’m curious if there are any existing models which could predict how a rapidly changing disease might affect the progression of an epidemic, or how slower...

Homework Statement Approx. 1/1000 has a disease, and the method of testing has a 5 % false positive rate. If a random person tests positive, what is the probability that he has the disease? Homework Equations I'm pretty sure Baye's theorem is the thing to use. The Attempt at a...

Assume there is a population of a given (even) size. One person is ‘infected’ in the beginning. During every ‘round’, everybody in the population pairs off and ‘interacts’ with her partner. If an infected person interacts with an uninfected person, the uninfected person is then infected. If two...

Freakin' ticks! I just got diagnosed this morning with Lyme's disease. Not too surprising since I live just three towns over from Lyme, but dang! Talk about throwing a monkey wrench into my plans! I'm doing a half marathon in three weeks and all my joints are grinding, I've got "sand" in...

Now I am going to throw away all of the assumptions of the original thread and make one other. Let's assume that the physicalists are right. There is no God or Creator. All that is is the natural result of the Laws of Physics, Chemistry and evolution. Who or what now do we blame for all...

Is it possible to prevent it? I heard that learning another language, solving puzzles and stuff like that could protect our mind against this sicknesses, is it true?

I saw this question on Swordfish (awesome movie!) and wanted to ask a variation of it here. If you had the chance to permanently cure all diseases, but the price of doing this was that you had to kill a child, would you? How bout 100, how bout 10,000?

So I apparently have lyme disease. The splotch I mentioned in the flu thread has been getting larger and darker (4 inches across by an inch and a half to 2 inches wide). Also my fever has been up to 103 a couple times in the past few days. And I have a couple more baby splotches on my arm and...

Hello, my name is Richard D. O'Neal, I have a question about lympatic Lymphatic system plays a very important role in immunologic defenses. But how can a physician determine the disease's main location ? Thanks a lot

Vampyred! I have a question...how long does it usually take a lab to do blood work on you? :confused:

Haemolytic disease and the rheasus blood group... Why do you get haemolytic disease in a baby ( not first baby) if the mother is Rh- and her anti D antibodies cross the placenta, yet it is fine to tranfuse Rh- blood to a Rh+ recipient, which will also contain anti D antibodies? Thanks in...

I think it is. Gay people trend to do what organism suppose not do. organism should **** the opposite sex.

In mad cow disease, perhaps the prions cause the brains naturally similar proteins to change into the new form because the new form is somehow more efficient to reproduce than the other, natural form. Perhaps it could be the path of least resistance for the brain to produce the protein in the...

I just read the following article and can't understand why stapling the stomach would be an expense that might get covered under insurance? http://www.washingtonpost.com/wp-dyn/articles/A52835-2004Jul15.html If stapling the stomach reduces the amount of food that gets in, is that the...

I have no clue of what is wrong with me. I had a chemistry test this Thursday and I had studied thoroughly two days before the test. When the day came, my brain completely knowcked out and I could not remember what I should do to solve the problems. Some of reasonings were successful because...

I didn't know it until the U.S. case of mad cow disease appeared. You see what happens when feedlots, etc., result to utilizing Cannibalism? I mean, feeding cattle the ground up remains of their own kind! Ugh. I think I will just eat fruit from now on, the only problem is I can never find an...
