Microwave Experiments Cause Sponge Disasters

gollum123 writes "Reports about a study that found microwave ovens can be used to sterilize kitchen sponges sent people hurrying to test the idea this week — with sometimes disastrous results. A team at the University of Florida found that two minutes in the microwave at full power could kill a range of bacteria, viruses and parasites on kitchen sponges. They described how they soaked the sponges in wastewater and then zapped them. But several experimenters evidently left out the crucial step of wetting the sponge. "Just wanted you to know that your article on microwaving sponges and scrubbers aroused my interest. However, when I put my sponge/scrubber into the microwave, it caught fire, smoked up the house, ruined my microwave, and pissed me off," one correspondent wrote in an e-mail to Reuters."

    There's this method of execution shown in Tom Hanks' 'The Green Mile' in which the guy to be electrocuted is seated in the chair and a wet sponge must be placed on top of his head. Some guy (Percy) with sadistic intentions 'forgets' to do this and the poor convict burns to death in the chair.

    In case of human IQ, the evolution feedback works in the wrong direction.
    Generally, the more intelligent, well-educated and well-established couples get children at a later age, and get fewer of them.
    The "dumber" and lower-class people reproduce faster, and there will be more and more of them.

    This effect is clearly visible both on a global scale (developed/developing countries) and locally (lower/upper class).

    Truly, we need the stupid to start killing themselves again. With the advent of birth control, human evolution is starting to go backwards. In 100 years they will talk about the benevolent reign of George Bush the Wise.
    You raise a very interesting point, those who take advantage of the opportunities presented to them in western society tend to reproduce at a much lower rate than those who get hammered and start breeding while the more capable are still in education.

    The fact that educated women want to establish a career before becoming mothers means that they start a family in their late thirties and consequently have fewer kids, sometimes they have no family at all as it is too late for treatment when they discover infertility issues. Basically the smart people aren't replacing themselves.

  6. How to really sterilise a sponge by giafly · · Score: 2, Interesting
    The only mention of water in the Microwave zaps germs on sponges article was as follows.
    Writing in the Journal of Environmental Health, Bitton and colleagues said they soaked sponges and scrubbing pads in raw wastewater containing fecal bacteria such as E. coli, viruses, protozoan parasites and bacterial spores.
    Seems to me that only very stupid people would follow these instructions.

    IMHO a better way to sterilise a sponge is as follows:
    1. Place sponge in a large, empty drinking mug
    2. Pour boiling water over it from a kettle and dunk it a few times using a spoon
    3. Place a small plate or saucer over the mug to retain the steam
    4. Wait until it's cooled

    The evolution feedback, in case of human IQ, has worked just fine till now. Almost all human institutions are organized in a pyramid-like structure: the more intelligent, well-educated people will be more at the top, leading. The "dumber" and lower-class people are more near or at the bottom, doing more of the menial work.
    Now, until we have robots (or other technological solutions) that can take over most of the unskilled and lower-skilled work, we do need these "dumber" and lower-class people or the entire economy and our way of life will come to a standstill. Or do you really think, that if everybody was more intelligent and well-educated, that we'd have enough people with PhD's who would find satisfaction in working at the checkout of a supermarket or cleaning toilets or ...?

    The question then becomes: what if we do get to the point where we have robots (or whatever) to do most of the unskilled, lower-skilled and maybe even medium-skilled tasks? We'd have 5 billion people in the world, "mostly" not well-educated and due-to the evolutionary feedback up till now a "big" percentage would not be intelligent enough to be well-educated. What should become of these people? What would they do all day if they're all unemployed?
    Even if natural selection would step in hard at that point and we'd be left with only with 1 billion people, all well-educated, what would THEY do all day? I mean, can you imagine 1 billion well-educated people working on innovations or being "artists"? Soon enough there would be little left to invent, or at least not enough to keep 1 billion people occupied, and then what? Spread out across the universe and colonize other planets? Sure, but seeing as everybody would ofcourse take all the knowledge with them there'd be nothing "real" to do on those planets as well, apart from just living. .... So, we'd have 1 billion people, of which 99.99% have nothing to do, except to just try and enjoy themselves. My guess is most of them would get really bored really fast...

    The "zero" in your score makes me laugh. Super patriotism of others for the win.

In both cases, and many others, a good reason for military conscription is in fact a lack of college. Which isn't saying your too stupid or poor to get into the college mind you. A good example would be my own father-in-law: extremely smart man.

    It's seems to really be a moot point whether IQ is genetic, social or monetary as an individual's children will (generally) be raised in the same social and monetary situation as the parents. No personal experience, but my father has been a guidance counselor at a High School since he retired from the military,(about 7 years) and he swears it's genetic. According to him, 95% of the time, if the kid is an idiot, when the parents come in for a meeting they're going to be idiots too, and the same thing holds true for the smart kids.

    Argh, I'm replying to an anon on a touchy subject....

    The Nazis performed eugenics to an extreme degree. I think that eliminating "stupid" people (using an arbitrary definition of "stupid") by encouraging them to kill themselves would qualify as a moderate-to-extreme form of eugenics. Once they started incarcerating political prisoners, gypsys, and in general bad people in concentration camps in the early 30s, it quickly became easier in germany to add other groups the general population didn't like, such as anyone unable or unwilling to "contribute" or "fit in" to society. Don't forget that Germany, and in fact, most of Europe, were horribly xenophobic at the time. The concentration camps quickly devolved to slave camps and then execution camps, which is a perfect example of the "slippery slope" concept in action.

    Eugenics is practiced with every prenatal screening, gene screening to discover genetic abnormalities prior to conception, and with almost every in-vitro process. Do you consider those "horrible"?

    These are controversial ethical debates. Some people, especially the disabled community, do not believe that those who are born disabled should be screened out. Of course, the definition of "disability" and "disease" varies greatly.

    I agree there's much debate on this topic. In a contrary view, there was a story in the insert in my Sunday paper this past weekend about a married dwarf couple wanting to ensure their child was born a dwarf. This would be intentionally producing a child with what is considered a genetic abnormality by, at a rough guess, 95+% of the population. Personally, I feel that intentionally disadvantaging a child in this manner, because they will be at a disadvantage in today's society, is not unlike unnecessarily amputating a new born's legs or arms at birth. The story also made mention of intentionally selecting deafness for a deaf couple. I feel the same way about that.

    This is merely encouraging a subset to remove themselves from the gene pool.

    Deliberately encouraging people to kill themselves would... land you in a fair bit of trouble, I think.

    Or do you hold that the Darwin Awards website is an abomination as well?

    More like insensitivity to loved ones.

    Telling someone to "drop dead" if you will, is not punishable. As an example of how stupid our society has become as a whole, I was by pure happenstance viewing an ad on TV this morning. It was of the new Lexus IS, and they had one on a runway racing against an IS dropped from a helicopter across the drop target. The ground based IS squeaks right under the falling IS in classic thrilling escaped by a hair style.

    What makes this germane to this discussion is the text that was apparently felt by someone that needed to be included in the ad. Underneath, it stated first off, "all ariel sequences were simulated", followed by "Professional driver on closed course. Do not attempt."

    Now, if you have to tell someone that measuring out 4000 feet on a runway and racing a car dropped from a helicopter @ 4000 feet is something you shouldn't attempt, I'd say that anyone so tempted should be allowed to go ahead and potentially remove themselves from the gene pool.

    Or let's put it another way: the more "advanced" a society gets the less applicable natural selection becomes. Why? Because societies in first world countries will try to safeguard its citizens against stupidity or any other "lack of fitness". Not only does it protect its citizens against natural hazards, such as wild animals, bad weather, famines etc. but it also strives to protect them from any new threats arising due to the new life style.

    The example in this case would be: guy hears about scientists sterilizing a sponge, guy rushes to the microwave in order to replicate the experiment, sponge catches fire, guy frantically jumps around in circles while microwave oven and room catches on fire, this sets off the fire alarm which in turn calls the firefighters, they extinguish the fire, guy sues everybody and their grandma, gets rich and procreates like mad..

    We have basically neutralized effects of natural selection on us by assuring the survival and procreation of individuals that would be "less fit". Instead we are subjected mainly to genetic drift, the other effect that determines the gene pool of a population.

    The movie Idiocracy actually takes it a step further and postulates that stupidity actually increases the "fitness" of an individual (i.e. a stupid individual is more likely to have children), thus a bunch of generations down the line we'll be living in an "idiocracy" such as the one depicted ;) - A funny movie none the less.
