Three-Dimensional Structure of HIV Revealed

Mutatis Mutandis writes "The BBC is reporting that a team of scientists from Oxford, Heidelberg and Munich has created the first accurate three-dimensional images of the HIV virus. The virus was found to have an average diameter of 125 nanometers, well below the wavelength of visible light. In the past the structure of viruses with a regular structure has been produced by 3D reconstruction techniques that work on a set of electron microscopy images of different viruses, but the irregular structure of HIV does not allow this. Scientists have now used a tomography technique that employs a series of images taken from a single virus, somewhat similar to the better known X-Ray CAT scan, but on a quite different scale." Structure also has a video of the 3-d rendering available for download. Relatedly an anonymous reader writes "A research team at Brown University has genetically modified bacteria found in yogurt so that the bugs produce a protein proven to block HIV infection in monkeys. The results offer hope for a microbicide that can prevent the spread of HIV, which now affects about 40 million people."

    It's the same way in the states. I live in NY, which has a relatively high percentage of HIV cases (HIV is very prevalent amongst poor African American and Hispanic communities - with additional stressors of a dense population). A friend teaches teens and told me that one of her students commented that it "wasn't a big deal" and that he'd just take "the pills" if he contracted it. He concluded by saying he wore no protection for sex.

    There is a perception that it is a rare, chronic, and treatable disease.

    Not that big of a deal?
    Society treats you like a leper. Most people wouldn't shake your hand if you told them you were HIV positive. Many people are so afraid of HIV, they would rather throw away the cutlery you ate dinner with than "take a risk" and wash it, if they invited you to dinner at all.
    Intimacy is all but impossible. How many people would knowingly have (protected) sex with an HIV-infected partner? Most people would not dare kiss you if you are HIV positive, much less any other intimate activity. With appropriate protection, it is perfectly safe, but good luck convincing someone of that.
    The financial strain is huge. Repressive therapy is quite expensive, and even if the patient is not paying the costs, someone is. The majority of HIV positive patients worldwide can't afford a tenth of the medication they need. Without adequate treatment, these same people will develop AIDS within 10 years of infection, and then the medical bills skyrocket, as even a minor cold calls for hospitalization.
    HIV is a slippery target. Every day could be the day that the virus mutates again, and becomes resistant to current therapies. Those who contract this new variant could very well be dead before medicines catch up.

    In short: Use protection, every time. That's all it takes. Would you play Russian roulette with a 1000-shot revolver? I hope not. Knowing only 1 in a thousand people dies of AIDS is no comfort when you are that 1.

    Aren't most ID proponents (like even many old-fashin creationists) keen on the idea that some evolution is possible, microevolution or maybe even some new species, but that certain changes are too big "leaps" (the human eye being a popular example)?

    Most ID proponents are for any argument which will support their position in a public debate & let them get religion into science classes. They don't really care whether they believe that argument, as long as they can fool the public.

    People don't have to stop having sex, they just need to be careful. It is like saying that "because driving kills most adults in US -- driving should be stopped". But all that needs to happen is for people to be careful. and here is where education comes into play. Dating doesn't have to be stopped, people should just not have unprotected sex on the 3rd date. Honest prostitution should be legalized. The number of the truly stupid would have to be reduced. On a large scale, education and better living standards might help. But if they choose not to listen, they will eventually end up in jail or dead -- it is their choice. They should be informed about and then decide.

    Those who are extremely stupid will end up in jails anyway -- it will be expensive to feed them but so be it, I'll pay taxes to keep my white trash neighbours in jail before I'll pay taxes to fund their drug use and their welfare checks.

    We do live in a world of self denial, we are even in denial about our denial (the same thing really...). Everyone today will defend their and others behaviors as "just natural" -- the animals do it, so I will do it too, It's in my genes and I can't help it. "The genes made me rob that store, your honor!" Pesonal responability and restraint is something that is fading away and there is not sign of it coming back.
