  1. I was reading some where on the internet that Canada and US spent more on healthcare in the 70's and 80's than the late 90's. and it is less than 5% of the GDP go to healthcare :eek: They also go on to say that the 90's in the US and Canada the goverment put cap on the number of doctors to drive the cost up and so there is a shortage of doctors. Also saying the amout of money per GDP per healthcare is lower now than the 70's and 80's .And the US spend more on healthcare than Canada. ****** The thing is healthcare is a business base on who has the money for treatment and fat cats who profit of sick people with little money trickling back to by new med supply or cover cost. . The shortage of doctors is artificially created to drive cost up.To fix problem build more med schools ,remove cap of enrolment to schools ,pay school tuition fees , bring immigrants in to work ,remove administration staff who make million a year ,lower wages to countries like Europe ,remove government and administration burecrats who jump in bad with intrest groups and business and make a million yaer being paper pusher . But this will not happen in the US :eek:people want to be rich and yet thing they can get what other Europe countries can get in service that is just digging their own hole and the same thing is happing with NASA. The car companies is other thing where people got too much money and too many benefits.
  2. Many of the things you say above was not there 50 or 100 years ago like Ct scan ,pet scan ,ultrusound ,MRI so on. Those things have been around for 200 years. But here is thing , cancer was a death sentence before.Now alot of people who get cancer live thanks to Chemotherapy ,radiation ,drugs ,surgery and lasers that was not possible 50 yaers ago or even 30 yaers ago. People who had diabetes or allergic to some thing died 50 years ago and now they can live thanks to drugs. Well Asthma you died 50 years ago now you got puffers ,drugs and IV's . If you had a parasite , fungus or virus you died But 200 years ago they discovered parasite , fungus and virus. Good to understand but this is playing god when you mess with people DNA.

  4. Why does the government put cap so there is a shortage of doctors? only allow so many doctors a year? And why have they not buid more med schools.When you look at the GDP heathcare get so little:eek:
  5. Keep in mind 98% of stuff above would not be possible with out electricity or the micrscope. There was not alot of progress in science or medicine in the middle age do to the chuch and alot of science or medicine was lost . The Greek and Roman medicine was very good :-)doing surgery and using herbs ,drinks,flowers even though 60% of the herbs ,drinks,flowers did nothing the other percent did work. (( Hippocrates of Cos maintains that diseases have natural causes and puts forth the Hippocratic Oath, marking the birth of medicine in the west. )) This guy was good to bad he was not in the middle age that thought sin was why there is diseases . The forbidding the dissection of humans in the middle age did not help.Like in the old days and today the church tries to stop progress in science or medicine . http://en.wikipedia.org/wiki/Timeline_of_medicine_and_medical_technology
  6. Why does healthcare cost so much? Like every year healthcare cost is so high .There is a shortage of doctors and the healthcare cost is so high . A cost of a MRI or CT scan is extremely costly and governments are having a very hard time to give money to healthcare . What is going on and why is it like that.Why is there a shortage of doctors. Why was the 60's, 70's, 80's better than now with high cost and shortage of doctors. I hear of long wait times in the ER why is that.Why is the cost so much higher than 30 or 40 years ago
  7. I'm doing a project in school on the medicine we have now and medicine in the past or years ago in the past.The only things I can think of ar. 1.liver, heart, kidney ,face transplant we have now not possible 50 yaers ago. 2.Working on a person brain or heart .No doctor would do that 50 years ago . 3.Microscope invented in 1800's allow us today to understand the microorganism and what causes diseases and illnesses. 4.The Microscope and computers / math allowed inventions in drugs. 5.People with HIV are living longer than 20 years ago. 6.People who have cancer is no longer a death sentence.( only some cancers are easier to treat and well others are harder to treat . 7.New advances MRI ,CT scan, x-rays not possible 50 years ago. 8.Understanding of cell and DNA not possible 100 years ago. 9.Understanding of the brain not possible 50 years ago. A1. There are cures for some cancers, fungi and parasites A2 There are cures for Ebola, and Bubonic Plague A3. There is cure for SARS A4 There is cure for some bird flue strains A5 Has for influenza some strains there is a cure. All of this stuff is treatable, and most curable, depending upon what parasite, fungi, cancer, and strain of TB. Anyways I cannot think of more or cannot elaborate.But I'm doing this project . If anyone will like to add than please do.Also any more information about microscope will help or advance math and computer models to find new drugs
  8. Who deleted my post? Anyways here was my post that should have got posted. Gamma, x-ray and UV are classed as ionizing radiation. Ionizing radiation can cause cell damage by causing cancers and genetic damage as well as skin burns. However, lower energy photons can also cause damage to cells and to the body in general, through different mechanisms. The body usually doesn't respond to magnetic fields. It does respond to electric fields High concentration electromagnetic radiation is not good for you.The stronger the current the stroger the electromagnetic field ans that is bad . Here is one from wikipdia . We are talking about biological so I will skip the electrical part. Health effects of electric power transmission
  9. The rocket exhaust gases and these makes the rocket go up.If there was no hole for the exhaust gases the rocket would not take off . The hole allows the exhaust gases and these makes the rocket go up. The Newton law is any object that is moving has kinetic energy .What is kinetic energy it is energy of motion .Any object that is moving has kinetic energy . The measure of its energy is its momentum.To eleberate in more detail momentum is mass and speed.The more massive the object is or the greater its speed , the geater it its momentum.A big car that is moving fast has alot of momentum and when it hits some thing it tries to keep moving Any object that is not moving will not move unless a force makes it move and any object moving will not stop unless a force makes it stop or slow down.
  10. They say this problem was fixed and it will not work.They say this was the problem in the old days and now it is fixed. +++++++++++++ Can a rocket engines be inprove by doing the following things? Can we get a rocket engines more powerful and fuel efficient by re-designing the combustion chamber ,inproving the thrust chamber ,amout of fuel burn or the layout of the thrust chamber where the oxydizer are mixed and burned? And cutting back on moving parts and heat ?I just thought inproving the combustion chamber or new layout of the combustion chamber or a new state of the art combustion chamber . Or cutting back on moving parts or heat.Or the amout of fule burn. It will be intresting to see what NASA is doing. +++++++++++++++++ Thay say NASA has done the above and there is no way for those things above will work. Anyways I'm lost has I know nothing about rocket engines .Will this work or not?
  11. Well Stem cells is not the only one that will stimulate bone growth or repair.This substance that is soft like toothpaste than gets very hard will stimulate bone growth or repair. So if you brake your bone and go to the ER they will put this substance that is soft like toothpaste than gets very hard and it will be like your bone. The substance that is soft like toothpaste than gets very hard is better substance the bone is made out of.
  12. And if it has no where to pushe ? Like if there was no hole on the rocket that what will happen? You mean if the mass has enough speed?
  13. Do they not have a howstuffworks for kids ?
  14. What I'm having a hard time to understand is tumorigenesis and why some proteins are bad. When the cell mutated or deregulated why can't the proteins function properly .Why is the protein different. Why can't they make a protein inhibitor they do it with HIV protease .
  15. Wow I did not know there was so much Chemistry . That takes care how they look for a cue but does not explain the conplex of the problem or why it takes so long for cure . It is not snap there is problem in 2 years there is cure it takes years and years some times 40 years to cure comes out.It is very conplex. I'm going ask for some web sites on the human body chemistry ,make up ,drug design.
  16. From my understanding it is the type of electromagnetic radiation and intensity and the duration of exposure . The type of electromagnetic radiation being the wavelength band. The intensity being how strong the EMF is A radio trasmitting at 80 watts is not strong but a radio trasmitting at 500 watts is vey strong. The Ultraviolet,X-rays ,Gamma rays are bad type of electromagnetic radiation do to cell damage. Other types of electromagnetic radiation cannot cause cell damage. The short wavelength have alot of energy it holds and the long wavelength have less energy .. I think most EMF are good if the trasmitting power is low .But I do not want to get job at a power station or MRI tech.
  17. I'm trying to understand Newton's Third Law of Motion: for every action there is an equal and opposite reaction. If a rocket does not push on air than what drives it? Is it internal pressure in the Combustion chamber ? When the gas escape pushes on gas accelerating it backward then the gas must therefore push forward on rocket:eek: The mass have be the same? Small mass cannot move big mass it has be the same mass.
  18. By changing currents you mean AC ? So only electronic devices or electrical device we changing currents AC ? Can you or someone elaborate that quote.
  19. I think the past 2 replies should have been posted in the thread understanding cancer. But I'm really trying to understand how drugs are made and how pharmaceutical companies go about looking for a cure.
  20. We do not want to stop cells that replicate only the bad cells that replicate .Sure cells have to replicate and divide to replace the dead cells or damaged cells. But you say the DNA in the cell tell the cell how to replicate or divide ?And the DNA in the cell does the various check-points ? When a cell is misbehaving what is it doing and why can't the DNA fix it? But the cells need protein to live .How can the protein be bad ? This what I do not understand how can the cells DNA get damaged? And how can the DNA fix it self? Some people can have bad food and smoke every day for 70 years and have no problem some people cannot do this for 10 years. Your body is so conplex and everyone is different. Anyways I will reply to your other posts soon.
  21. I'm looking for web site other than Wikipedia and howstuffworks at a elementary level not high school level .The problem with Wikipedia and howstuffworks is it is at a adult level . I need web site at elementary level that walks their grade 2 to 8 on biology ,electricity ,space rockets ,computers , medicine:eek: I'm try to learn and understand. With pictures ,illustrations and simple english.
  22. Why do people call electronic devices or electrical devices radio frequency or part of the spectrum when it is not Radio,Microwave,Infrared,Visible, Ultraviolet,X-rays ,Gamma rays. I know every electronic devices when turn on or electrical devices when turn on have Electromagnetic field or any electric current have a Electromagnetic field . I know if the electromagnetic field is strong it can cause interference.That is why some times radios get interference from power lines ,cell towers ,electric saw if the electromagnetic field is strong.Any electronic devices or electrical devices cause interference if the electromagnetic field is strong. But can EMF do harm to the body or get cancer ?Are EMF bad for people.What is SAR ??
  23. Yes every cancer has different symptoms but basic of what cancer is cells gone bad replicating and taking over. What do you mean bt agents .Can they not come up with a drug that is not poisonous . So they have to find a way so the drug is not alter by the body chemistry . The idea how the pharmaceutical companies go about looking for a cure is conplex .Do they use math or different combinations ?
  24. I dont really understand Stem cells and how it will stimulate bone growth or repair.Some say Stem cells can be used to will stimulate cells or tissure growth or repair too !!
  25. I think the debade part you hear on the news about evolution is people who have problems go to hospital or see a doctor. And believe the body is starting to reject drugs like the flu virus.After time the virus , bacteria or parasite find way around the drug.And believe medicine in 21 century is doing more harm than good for the body.By the immune system too depended on drugs and technology to live.
