  1. I think nec209 is pointing out that the monetary incentives often don't lead to medications that save the most lives; a company might spend millions on a drug to treat "female sexual arousal disorder" because they believe it will sell well, but not fund research into a tropical disease because those afflicted are often too poor to afford treatment.

     

    That had pathgans that mutate or have many strains.

     

    What I will like to see is the private sector deal with the profitable side of medicine and the government deal with the non profitable side of medicine .

     

    The economic zones in China has worked well with state run and private .Well the USSR all state run did not worked out so good .

     

    Its up to you to tell the government to cough up millions of dollars in cash every year for research.

  2. I;m no sure if this is biomedicine or biotechnology.

     

    If it is biotechnology that is good place to start.Well Scientific American and popular science may be good place to read on what they are working on and what is coming out.

     

    Or go to the library get books on biomedicine or biotechnology.

     

    would medical journals or publication explain in a simpler terms? I know some times Scientific American can get advance even for the pre-med students.

  3. Looks like a cure for HIV around the corner.

     

    Washington - US scientists have discovered the most effective HIV antibodies to date, which could be used to find a vaccine for the virus, according to a study published in Science Thursday.

     

    A team of researchers coordinated by the National Institutes of Health (NIH) found the two proteins that can neutralize more than 90 per cent of known global strains of HIV.

     

    The VRC01 and VRC02 antibodies neutralize more strains with greater strength than any other previously known antibody, the study said.

     

    After finding out how the antibodies work and where they attach to the virus, the scientists have started developing a potential vaccine. They also said that their work could be used in HIV treatment.

     

    "In addition, the technique the teams used to find the new antibodies represents a novel strategy that could be applied to vaccine design for many other infectious diseases

  4. Will the universities and non profit groups/government run the pharmaceutical not the private sector.

     

    That look at the dirty sloppy rich pharmaceutical companies .Most of the fruits have been picked it is getting harder and harder to come up with new drugs now for this reason.Also there is less and less incentive to come up with new drugs to fight infectious disease do to new strains ,mutations and so many new pathgans every year coming out.Where is incentive to come up with drug to fight TB or AIDS virus when in year or more it can mutate or have many strains of the TB or AIDS virus .Look at comman cold so many strains.With so many infectious disease out there and new one coming out every year and so many strains ,mutations there is less and less incentive .

     

    Who is going spend 2 billion to fight TB or AIDS virus when in 2 or 3 years it can mutate .Who is going spend 2 billion to fight comman cold with so many strains.

     

     

    The pharmaceutical companies want to get dirty rich and how to do that is vaccines and birth control pills ,high blood pressure bills that is where the profit is not infectious disease .

  5. Is it called biomedicine or biotechnology that deals with cloning ,stem cell ,cell engineering ,organ transplant ,artificial organs ,genetic engineering and nanotechnology so on.

     

    If so than may be I should get some books on this that talk about it.Will I can get much better reply to my post and much more what are cutting edge technology coming out and what they are working on and what is coming out.Like artificial skin ,artificial bone ,3D printing ,artificial organs ,stem cell ,organs grown in lab,pig organ transplant ,,cell engineering so on.

     

    Than biomedicine or biotechnology deal with this and I should get some books on it.

  6. The thread title is asking about "best results."

     

    In my opinion, that refers to at least an average state of well-being.

    People on artificial organs are not at least an average state of well-being.

    They're living, and I'm sure they like that.

     

     

    Well artificial organs are so very very hard to make it take other 50 years or more before a artificial liver or artificial kidney crude prototype is out.Yes they have a working external belt kidney but it is crude and only a working prototype .

     

    Yes they have prosthetic arms and prosthetic legs but they are crude too.

     

     

    I'm not up on stem cell or organs grown in labs but this looks more promising than artificial organs .I also hear that pig organ for transplant look promising .Well artificial organs are very very very hard to make .

  7. --stem cell to repair damage organ/tissue

    --stem cell to grow new organ.

    --pig organ for transplant

    --artificial organ

    --organ grown in the lab

     

    Out of the above what do you see posable in 15 to 20 years.I say stem cell to repair damage organ/tissue and may be pig organ for transplant. Well stem cell to grow new organ and organ grown in the lab is still other 50 years out.

     

    Well artificial organ seem to be very very very hard to make .We have a artificial heart but it is used temporary and most people do not live more than a year on it.Has for a artificial liver and kidney not even close to a prototype it be very very long time before we have artificial organs.

     

    What are people thought on this and what do you see the best results in the next 15 to 20 years.If money grow on strees out of the above what should get the most money.

  8. Sorry I cannot find a book or any information to clear up the debate .

     

    Some say nerve cells ,brain cells ,heart cells or the spine does not repair or divide and some say it takes 50 years or more to repair or divide.

     

    Why is this not proven or dis-proven ?

    Other debate among science if myth or not or where it got stated is stress , anger ,frustration can cause ulcers or hernia.

     

    Again why the debate hear .

     

    What is with science today.

  9. After watching many programs on discovery health like trauma in ER ,code blue ,mystery diagnosis so on.Reading books and blogs so on.

     

    Doctors say it could be infection or not or say it looks like a infection not sure what type of infection.Or they say ya white count is up or do a LP spine.Or they say he has the symptoms of a infection .

     

    I'm confused :eek:I thought they do blood work to find out if it is a infection or not and type of infection .And I thought doctors do not give meds to they know what type of infection .

     

    what is the confusion if it is a infection or not or a confusion of what type of confusion .

     

    If I got sick and go to ER and the doctor should have no problem if TB ,HIV, swine flue or what ever.

     

    Is a infection not true science? Also friend I know had a hernia and seen like 5 doctors before a diagnosis and the doctor was saying that a hernia is hard to tell.

     

    Is it true hernia is hard to tell or did he get bad doctors ?

  10. So is it true the moon is moving away from the earth and the earth is slowing down when it comes to rotate ? Is the 24 hour clock going be 27 hours or more? DO to the earth is slowing down when it comes to rotate ?

     

    It was a show like the show called life after people.I do not really understand the science.

     

    One show was on running out of oil, other the population of world 14 billion ,sun burns out ,the moon moving away ,earth is slowing down when it comes to rotate , asteroid hits earth ,earth magnetic field , earth axes and poles so on.

     

    So is going happen soon or much later on?All life on earth gone? What is the point of like if in 50 years all like on earth is gone do to moon is moving away from the earth or the spin of the earth is slowing down.

     

    WHY WILL the show not say when this is going to happen. Can it be stoped some how.

  11. All those thinks I posted above science should have a good understanding of it by now.It been years and years of research.

     

    You would think in 15 or 20 years from now they will know how to repair heart cells or the spine .

     

    There was video on youtube of long term meth addic of years of smoking meth and most brain cells gone.After not using meth the brain was slowing making new conntections or making new brain cells or trying to repair it.Do not know if this is true or not but there was some video on youtube .Now they say people who drink or smoke pot kills brain cells.

     

    The UV rays from sun can lead to skin cancer and stress may cause hair loss ,thin hair ,going bold .

  12. Some say nerve cells ,brain cells ,heart cells or the spine does not repair or divide and some say it takes 50 years or more to repair or divide.

     

    Why such confusion.

     

    Other debate among science if myth or not or where it got stated is stress , anger ,frustration can cause ulcers or hernia.

     

    Also say hair loss ,thin hair ,going bold ,gray hair is do to stress , anger or frustration can cause it.

     

     

    Why such a confusion among scientists.

  13. There was show that was saying with out the moon or with out the earth that rotates all life on earth is gone.

     

    What causes the earth to rotate.

     

    Billions of years ago, the formation of the earth from dust and gas coming together caused it to spin.Than large rock hit the earth making it spin quite fast. This also formed our moon.

     

    There is a very slight wandering of the rotation poles. It is due to tugs from other bodies in the solar system, continental drift, and earthquakes.

     

    Also the moon.

     

     

    What factor does moon have on earth and if the moon was gone what will happen?

     

    moon exerts a very strong gravitational pull on the earth. Although it has several effects the strongest implication of what would happen if earth had no moon would be on the tidal waves of the ocean (which would disappear) and the weather patterns, which strongly correlate to the tides.

     

    But the implications are greater than that...because the moon also affected tides of magma in the earths creation, the earth would not exist as it does now without it.

     

    moonlight and how bright the sky would be if there was no moon

    the earth's rotation slowing down

    animal behaviour

    climate change

    the spin of the earth and its affect on winds

     

    All life on earth will be gone.

  14. That is 25 tons, so as far a a 1000 ton payload maybe not, but to say that the laws of physics don't allow for more than eight people to go into space is ridiculous. Unless you can show me the Max people allowed to go into space law.

     

     

     

    Well 25 tons is a big difference than 1000 .Also the space shuttle and old apollo program are under attack has being too big and too conplex.The mood of NASA is build smaller and simpler .

     

    If the space shuttle was big leep in saving money NASA would have had other space shuttle.In the 90's there was research into new shuttle and the x-33 was among them even smaller space shuttle than what they have now and all turn out non was economical.

     

    MASA mood now is use smaller rockets one for payload and one for people than one big rocket for both.

     

    Countries are not looking for bigger rockets and space shuttle but smaller and simpler.If money came from the sky than we can have bigger rockets and space shuttle. And spend $$$ every day on research.

     

    After doing some more reading if in 5 or 10 years from now they send 10 or 15 people on rocket to the space station or the moon that would be a breakthrough.Now 50 or 100 people not going happen or 1000 tons.No propulsion we have or know of on the drawing board like plasma propulsion,antimatter propulsion ,laser propulsion, explosion propulsion, fusion propulsion , ion propulsion or fission propulsion will allow it.

     

    If a SSTO like a DC-X will allow 3 people to go up to the space station that will be a big breakthrough !!

     

     

    The propulsion we have or any thing on the drawing board even the once that are more scfi now like antimatter propulsion and fission propulsion will not allow it.The law of newton's third law does not allow big ships depict in scfi shows like star trek but the opposite.

     

    Remenber boats and planes where dirt cheap and allowed bigger and bigger over time. This is not the case with rockets.A rocket we have now is like big cruise ship to launch a small capsule to the moon!! And you want 1000 ton payload into space.

  15. How so? Just make a bigger rocket. Or a better rocket (nuclear). Or even without a rocket (space elevator or launch loop).

     

     

    Sure it may be possible to have bigger rocket or space capsule to take 10 or 15 people to the moon or mars but at what cost.

     

    The space shuttle was nice idea but slap in NASA face with cost .The X-33 that was to replace the space shuttle was nice idea but again cost .The space plane on rocket sound like a good idea but cost.

     

     

    NASA is even scaling back the apollo program to use one rocket for payload and one for people and smaller rocket!!! The mood that going on at NASA is built smaller ,simple and cheaper ways to go in space than bigger ,more conplex ways .

     

    Cost is big factor .If money came from the sky every country could have a space shuttle and X-33 not say space station.

     

    We may be able to built bigger rockets and bigger space capsule but the cost is factor.

     

    It cheaper to bult smaller ,simple rockets and smaller capsule than big capsule .

     

     

    I know there are many research going into space planes where it takes off like plane to x number of altitude and the rocket kicks in.Others are space planes on rocket .Some are looking at attaching a space plane to airplane and use airplane to take the space planes up to number of altitude than the space planes un-hooks and shoots of.

     

    Other people are looking at SSTO like the DC-X and some looking at Kliper a partly reusable manned spacecraft.

     

    But other than research I do not think any country will go this way but old way of going up. On less there is other cold war I do not think you will see any country going this way .

     

    Why the old way? It simpler ,cheaper to built ,test and use .The other way need research and cost more and more conplex to built and use .

     

     

    So space planes ,DC-X ,x-33 ,Kliper ,rocket combo planes and space shuttle sound nice but too costly:eek::eek:

     

    Other than research I do not think any country will go this path to do cost but take the old path like before.In fact even the old way that is simpler ,less conplex ,cost less :eek::eek: Is too costly !!!

  16. Moontanman no I do not believe any technology we have now or any thing cutting edge technology that may come out will allow 1000 tons payload into space.That is crack pot idea .

     

    The payload is problem.No I do not believe any technology will allow more than 10 people to go up in space on a rocket.

     

    No propulsion we have or know of will work.I was hopping that plasma propulsion,antimatter propulsion ,laser propulsion, explosion propulsion, fusion propulsion , ion propulsion or fission propulsion may fix this problem we have but no it will not.

     

     

    The laws of physics does not allow more than 8 people to go up in space.

     

    That put simple .

     

     

    real world.

     

    You need this

    http://scienceblogs.com/startswithabang/upload/2009/12/the_perils_of_planet-hopping/A15SaturnV.jpg

     

    to have this .

    http://www.fly.co.uk/blog/wp-content/uploads/orion.jpg

     

     

    And you want mass immigrants to go to moon or mars to live??? A under- water city or dome city to live and work on earth is more real than this.

     

     

    Even if space plane on rocket like this could take 10 or 15 people up to the space station or craft in space and take that to the moon or mars would not work do to cost and not taking up enough people.

     

    http://www.spacetoday.org/images/SpcShtls/SpacePlane/OrbitalSpacePlaneLaunch600x450.jpg

     

    It have to be $2,000 per person and craft that can take up 50 or 100 people and it not going happen now or any thing on the drawing board we have now .The laws of physics just seem to not work this way.

     

    After doing some more reading that put it simple space is for probes and going to the moon or mars to visit not to stay and by astronauts that cost $$$$$ only the state can pay!!!That is all !!

     

    No propulsion we have or know of on the drawing board like plasma propulsion,antimatter propulsion ,laser propulsion, explosion propulsion, fusion propulsion , ion propulsion or fission propulsion will fix this problem .

  17. I'm curious, project Orion which used nuclear detonations to launch a space craft into orbit is being considered as usable technology but the idea of gaseous fusion (nuclear light bulb variant) which could, with relative ease, lift 1000 tons into orbit and return under power one stage, reusable, ground to orbit and back, is not even considered?

     

    Sorry what do you mean ? There is no fusion power station or fusion rocket just like there is no plasma rocket.

     

    The orion project and daedalus project was testing they where doing but than stoped .None of the above propulsion talked about here deal with the problems talked about here.

     

     

    The plasma propulsion,antimatter propulsion ,laser propulsion, explosion propulsion, fusion propulsion , ion propulsion or fission was on the drawing board to deal with trevel close to the speed of light and does not deal with cost or liffing from earth .It was not replacement to chemical rockets.

     

    When it came to the first boats and airplanes they where dirt cheap and the physics allowed over time to build bigger and bigger boats and airplanes and this not the case with rockets .

     

    If the boats and airplanes of today will not allow more than 4 people and cost $1,000,000 per person we would not have this too!!! The physics of going in space is very costly and does not allow more than 8 people to go in space on a rocket .So payload will be big problem and cost.This was not the case boats and airplanes .

     

    You do not see a big cruise ship just to move small raft.This is the case of rockets.

     

    The rocket is like a big cruise ship just to move payload like small raft in space.

  18. Would it be possible to take up 50 people even with new technology coming out that are more scfi now and hope we run into no problem.

     

    That depends on your definition of "possible." Is it a violation of the laws of physics? No. Is it politically viable in any rationally foreseeable environment? No.

     

    No I mean the cutting edge technology that is coming out is it possible.The technology we have now does not allow more than 8 people to go up in space at a time on a rocket.

     

    What about building a space station or space ship in space to take 50 or 100 people to the moon or mars in one trip ? Would this be possible? Take up 5 or 8 people in small rocket to the space station or bigger space ship and take the space station or space ship that can hold 50 or 100 people to the moon or mars in one trip .

     

    Again, not a violation of the laws of physics, but it does nothing to address the cost. Right now it costs (to use recent historical numbers) $20M for a person to get to the ISS. Even if the ISS was a teleportation device that sent the guy to Alpha Centari for free, you're STILL talking $20M per trip. Until you figure out a way to get to LEO on the cheap and easy, NOTHING about space will be cheap and easy.

     

    Is it even possible with todays technology or cutting edge technology coming out the pipe to built a space ship or space station to take 50 or 100 people to mars..

     

    Sure such a breakthrough could bring the cost down. But could it bring the cost down ENOUGH? No, I don't believe so.

     

    From what I read plasma propulsion,antimatter propulsion ,laser propulsion,explosion propulsion or fusion propulsion or ion not to say fission have low thrust and high inpulse and can never lift any thing from earth.

     

    Only the orion project and daedalus project have high thrust and high inpulse .

     

    From what I read none of the things we have now or cutting edge technology coming out like plasma propulsion,antimatter propulsion ,laser propulsion, explosion propulsion, fusion propulsion , ion propulsion or fission deal with fact that they can never lift any thing from earth and will not bring cost down.

     

    Nothing on the drawing board seem to fix the problem.The future looks sad. On less there was some breakthrough in atigravity:eek::eek::eek: space is for the astronauts and may be the rich in the future.

     

    The laws of physics just seem to paint space is for astronauts and may be and I use the word may be the rich and cost lots and lots of $$$$$ and we will never be able to send up more than 8 people on rocket and never send more than 8 people to the moon or mars on craft.

     

    The fuel will be a big problem and it TAKE MORE fuel than the payload :eek:The fuel they use now is just not powerful enough so need lots and lots of fuel just to lift 10% of the rocket into space and shedding the 90% empty fuel tank.

     

    And from what I read it sad but plasma propulsion,antimatter propulsion ,laser propulsion, explosion propulsion, fusion propulsion , ion propulsion or fission will not fix the problem I talk about.

  19. My mother thinks that you get colds from being cold and also that beening cold lowers your immune system. Why do most people think that your immune system stops your body from infection? Is there any other silly disease myths that aren't true?

     

     

    Cold or hot has nothing to do with the immune system .

     

    Tried ,run down and stress does.Very hot or very cold kills most germs.

  20. And right now not even the wildest, craziest far out dreamers in the industry think in such terms. When I came up with the number $150k earlier in the thread that was using crazy-optimistic assumptions. Laughable assumptions, really. The development of a technology that would allow a trip to Mars for $15M per person would be deemed an AMAZING revolution in propulsion. Even it would be "off the charts." And you want $1k? Not gonna happen even in your great grandchildren's lifetime.

     

     

    Okay what about plasma propulsion,antimatter propulsion ,laser propulsion,explosion propulsion or fusion propulsion that are very much scfi now and if there was a breakthrough in these technology to allow it , could this not bring the cost down and take up more payload.

    Would it be possible to take up 50 people even with new technology coming out that are more scfi now and hope we run into no problem.I believe the most people taken up where on the space shuttle is 9.Would the technology allow to take up 50 people even with new technology they are working on now.

     

    What about building a space station or space ship in space to take 50 or 100 people to the moon or mars in one trip ? Would this be possible? Take up 5 or 8 people in small rocket to the space station or bigger space ship and take the space station or space ship that can hold 50 or 100 people to the moon or mars in one trip .

  21. Already stated, but no, it's just pushing a hot gas through a nozzle. Same concept as chemical propulsion the only difference is the source of the heat (burning something vs. running it through a heat exchanger powered by fission reaction).

     

     

     

    I don't know the difference of burning something vs. running it through a heat exchanger and what is better. Well pushing a hot gas through a nozzle is good idea but the question is what gas has more thrust and last longer with out the fuel used up

     

     

    Light gases work better. Not gonna get anything lighter than hydrogen. For the purpose of fission-powered nuclear rockets, the fact that hydrogen is useful in fusion is irrelevant.

     

     

     

     

    What do you mean.

     

     

     

     

    Irrelevant. If you're looking to expand to the stars to save the planet from human overpopulation you're barking up the wrong tree. Right now it costs on the order of $5,000 per pound to get to GSO. That's not even to the Moon, but it's a useful benchmark.

     

    Suppose that tomorrow there was some breakthrough that lowered that to $50 per pound. A reduction in cost by two orders of magnitude!

     

    What would that mean?

     

     

     

     

    Has of now the only people that can go in space is astronauts and just may be the rich.The lower income ,middle income ,upper income do not have enough money to go in space.Only the astronauts and may be the rich if the private sector can pull it off.

     

    The only way we can deel with overpopulation is spend trillion of money on rocket research and hope revolution spark can bring the cost down has going on plane ticket from LA to New York.If the laws of physics does not allow it than no one will be going in space other than astronauts and may be the rich in crude way.

     

     

     

    Well, the Apollo command module weighed about 5,000 pounds. That supported 3 guys for what, 1 week? A Mars mission is going to take a lot more support and such. I'll be VERY nice and say that a Mars habitat would weigh 9,000 pounds for 3 guys for - what is it to Mars? - 6 months? In any event... Call it 3,000 pounds per person. Again, this is insanely generous if we're talking a resettlement and not just a flyby of Mars. Still, let's run with it....

     

    If there is a revolution sparks that say in 10 years that can bring the cost down to 1,000 per person than I and you have enough money to go to mars.If there is revolution sparks it may allow up 500 people or 1,000 people per rocket to mars .Has of now nothing is over 10 .

    Ah, but then we can expand "us" to include everyone on earth, something we couldn't do without having a "them" off our planet. I really do think going into space will unify Earth, at least a little. (If done internationally or independently.) Also, we'll once again have a frontier, rather than having to fight others for territory.

     

     

    What are you talking about .No one can go in space other than the astronauts and may be the rich in the future.

     

    Living on mars the moon ,space station sound nice but put it simple the technology and money does not allow it now.

     

    Space mining ,looking for other resources and energy in space sound cool but the technology just does not allow it ,It cost more just to get there in energy than what we will bring back.

     

     

    The only way this can happen is a revolution in space rockets.Where it is cheap has getting on air plane and the technology that can do it.

     

     

    Put it simple we are going in space in rafts not even columbus ship.

  22. In earlier tissue engineering a basic 3D scaffold made using processed animal collagen to which cell cultures were added to build the structure. These scaffolds were, say, in the form of an ear, nose or even a urinary bladder. The cultures grew in this scaffold until they matured and yes, they are implantable - several patients have new bladders that were grown in a lab. This type of scaffold dissolved in time and is replaced by naturally growing collagen.

     

    Why does the scaffold have to dissolved ? And why add cell cultures to the scaffold ?

     

     

    Now they're working on literally 'printing' the structure one 2D layer at a time, including natural collagen tissue, until the full 3D structure is complete. If successful we're talking the ability to manufacture replacement organs or other parts.

     

    What the differnce of using natural collagen and animal collagen ?

  23. Yes from doing internet search I found this.

     

     

     

    Foamy Urine

    Sometimes people perceive foamy urine as "bubbles in urine." This may not mean anything if it only happens once in awhile, and doesn't seem to be getting progressively worse. It could just be from urinating rapidly, which can come from dehydration. Drink plenty of water for awhile and see if it goes away. If it doesn't go away, then it could be a sign of protein in your urine (proteinuria), which may indicate a kidney infection. It's best to see your doctor if you're concerned.

     

    Proteinuria

    There's almost always some trace of protein present in urine. But when too much of it is found, it could be proteinuria. There are vessels in the kidneys that filter water and waste, but still keep protein and red blood cells in the bloodstream. When these vessels, called glomeruli, are damaged or inflamed, they allow for the passage of too much protein. When the excessive amount of protein reacts with the air when you urinate, it hits the water and produces a foamy urine.

     

    Vesicocolic Fistula

    A fistula is an abnormal connection between two body cavities. A vesicocolic fistula means that a connection has formed between the urinary bladder and the colon. Sometimes an edema, an accumulation of fluid beneath the skin, can form on the base of the bladder. When air bubbles are released from the middle of the edema, they can show up in the urine. This could be a symptom of Chron's disease, a tumor, or it may not need treatment at all. Only a doctor or urologist will be able to tell for sure

     

     

     

     

     

    Urinary Tract Infection

    Bubbles in your urine stream could also be caused by a urinary tract infection by a gas-forming organism. This usually only occurs in people with diabetes. But if you're aging and haven't been diagnosed with diabetes, that doesn't mean you don't have it. Speak with your doctor.

    Like I said it could be this or that and the only way is to see the doctor that does tests to find out what all these things are.
