  2. Sugar/Honey on Potato Powder Stops Bleeding, May Help Surgery · · Score: 3, Interesting
    If you don't happen to have a supply of potato powder around, table sugar is reported to have a similar effect.

    I don't know about the clotting effect, but sugar (and even better, honey) can help prevent infection in wounds. It works the same way that concentrated sugar and salt solutions work to preserve fruits and vegetables without boiling/sterilizing in preserves and pickles. The solution MUST be sufficiently concentrated to prevent bacterial growth. Pouring salt on a wound would be just too painful, but sugar and honey both work.

    Honey is even better for treating wounds than sugar for (at least) two reasons: It's already a superaturated sugar solution right out of the jar, and it contains, in addition to some interesting sugars (mostly levulose, maltose), some natural antibiotics/bacterial growth inhibitors.

    Hydrogen peroxide and blood. I really don't remember a thing about the chemistry other than it makes a lot of heat that sterilizes your cuts...

    IIRC it's a simple oxidation reaction, what with hydrogen peroxide (H2O2) being a strong oxidizer and all.

    BTW it's not the heat that "sterilizes" your cuts. For that you would need something like 121C at 20 pounds of pressure for 20 minutes or so, like yer average autoclave. H2O2 is an oxidizing agent (a very powerful one - there's a reason that the stuff you buy at the drug store is only 3% H2O2) and a bleaching agent. IIRC It's the oxidization that makes things foam and the bleaching that kills (some) bacteria.

    It does NOT sterilize wounds. It can, however disinfect them sufficiently to speed healing.

    IMSMC, if you use the really dilute peroxide you get in a drug store, it won't do much, you need a way stronger solution from a lab or something.

    The dilute H2O2 from the drug store produces plenty of bubbles when applied to a bleeding cut, and would presumably do much the same thing to a blood sample in a lab demonstration. But you have to use a rather fresh bottle of H2O2. Over time it reverts to H2O, and won't do anything to the blood except lyse the red cells, which doesn't look near as impressive (not even if you look under a microscope). The problem for a lab demonstration is probably not the H2O2 (the dilute stuff needs no warning labels) but the blood. There are some pretty serious rules for handling and disposing of blood these days, in the age of AIDS and other blood-borne pathogens/diseases.

    Even animal blood requires some rather intensive paperwork for disposal. I know - I have to deal with some of it for my job.

    With the africa continent slowly turning into desert, I am not sure what can be done to preserve the natural wild african elephant.

    There is some evidence that desertification in Africa is, at least in part, caused by human activity such as overgrazing and attempting to grow row crops on unsuitable land. But even if it's entirely due to non-human factors, it's unlikely to be deadly to all large land mammals. Habitats may grow or shrink, but barring things like asteroids slamming into the planet it's not likely that they'll vanish completely, particularly on a large land mass like Africa. Small island environments are another matter.

    Europe isn't rich because it stole but because it worked innovatively.

    Compromise: Europe stole innovatively. It made use of the new things that it found and borrowed or stole. Without the orient, Europe would have no gunpowder or pasta. Without the Americas it would have no corn, potatoes, tomatoes, tobacco, squash, peppers, chocolate, coffee etc. There was far less famine in Europe after contact with the Americas than before.

    The developed world is not rich because the rest of the world is poor. Its rich because it started using better methods to produce, manufacture and trade earlier.

    Often those very methods were borrowed or stolen, though Europe had a fair share of innovation too. The main reason Europe succeeded so rapidly is becuase it applied those methods on a grand (often unsustainable) scale.

Do we WANT robots performing tasks for non-experts? There are more than enough human non-experts around, and we keep making more. I guess it just seems more sensible to me to work on making robots that ARE experts. Particularly if they're made to be expert at things human have difficulty doing.

    Gestures and expressions are just another form of communication, and if you want to use them to communicate with your robot, be my guest. But gestures and expressions are extremely subtle (fractions of a centimeter in eyelid position can communicate volumes) and alarmingly variable, at least as humans use them. They also very subject to contextual cues. I expect that getting a robot to reliably recognize and interpret human gestures and expression will be far more difficult that getting it to recognize and interpret human speech. With speech we at least know most of the rules. We're still learning about nonverbal human communications ourselves.

People you would never ride with by choice. Even though they make up a small minority of the bus- and subway-riding public, they're enough to spoil the experience and make one not want to ride public transportation.

    The dedicated track part could still be a problem. Americans like to go where they want, when they want (doesn't everyone) and with the ready availability of (polluting, road-clogging) cars, I don't see them opting for any track-based transport system in the near future. Americans also take a kind of pride in their vehicles (witness the huge number of heavy, expensive, rollover-prone "off-road" vehicles that have never been off a road).

    I declare the global social space we are building to be naturally independent of the tyrannies you seek to impose on us.

    If it were naturally independent of tyrannies etc., there would be no need to declare it so. It's not natural. Those who inhabit the internet have made it so, and they (we?) can unmake it. I hope that never happens, but it could.

    This is the same complaint I have about another great document - one that declares that there exist certain "inalienable rights", endowed by a creator. If in fact those rights were inalienable, there would be no need to declare them so. The rights exist not because a creator granted them, but because people decided they should have them. They're not inalienable. People might someday decide those rights don't matter. Then those rights would cease to exist. I hope that doesn't happen either, but it could.

    You have no moral right to rule us nor do you possess any methods of enforcement we have true reason to fear.

    Leaving aside the moral right, it's important to remember that certain powers can and do have the means to interfere with the freedom we now enjoy on the internet. In many parts of the world, governments hold a great deal of power over the flesh and blood of their citizens. They may not have the same kind of powers over the thoughts of those citizens, but they can enforce their powers over how those thoughts are expressed, in speech, the press, and yes, on the internet. There are tools to thwart their efforts, but not everyone can gain access to and use those tools. This sort of tyranny may not affect you or me (not now, not yet), but it affects others, and it erodes away the freedom we enjoy on the internet.

    So why I agree with the sentiment "leave the internet alone", I think the tone of this manifesto is far too smug. It seems to say "leave the internet alone - you don't really have a have a choice because none of your intefering affects us anyway". A more realistic declaration might be "leave the internet alone because by doing so you will benefit". Then document the benefits. Document also the costs and unintended consequences when the internet is not "left alone".

When new observations come to light, theories are be revised to reflect them. Religion (well all of the ones I'm familiar with) is based on eternal capital-T Truths. No amount of observation can disprove them or cause them to be revised. If something is observed that seems to contradict the Eternal Truths, then the observations are rejected.

    This having been said, most religions (even most forms of Christianity) don't seem to have a problem with the theory of evolution. They recognize it as a valid SCIENTIFIC principle. Which has nothing to do with valid RELIGIOUS principles. Observations - the best ones we have to date - indicate that life on Earth evolved from earlier forms. These observations say nothing about Eternal Truths. Nothing science says about human origins can contradict religion, and nothing religion says about human origins can contradict science. They're two very different things.

    The creationists seem to have confused science with Truth. In that way they have elevated science far beyond its humble position, and they want to place their Eternal Truths on the same lofty pedestal. But they are in for a disappointment. There is no pedestal. Scientific theories are revised all the time. Sometimes they're discarded altogether. No scientific theory occupies a pedestal as lofty as the one religion already has.

    The Biblical account of creation has endured for thousands of years. It has important moral messages that still resonate today. So do the creation stories of myriad other religions. They still have value even if observations indicate they didn't happen exactly as described. They're not science and they never will be. But so what?

    For me, I'll stick by science for things like the history of life on earth, the positions of the planets WRT to the sun, etc. It just seems to work better for me.
