The state of soil science v. medical science
Comments (18)As a student in the field of medical science, I have to say that it's totally false that modern medicine has a good grip on the way the human body works. Totally false. For some reason, we in westernized societies, America especially, tend to look at the medical establishment as some sort of golden god. We are sick, we are getting sicker by the day. Our children have more allergies, asthma and chronic health conditions than any generation EVER has. And the experts can't even begin to agree on why so many children now suffer from anaphylactic peanut or dairy allergies, why the incidence of autism has skyrocketed or why healthy children are now developing shingles, which used to be a disease of the elderly and immune compromised. Doctors still do not routinely recommend or even understand probiotics, even though many still prescribe antibiotics for every ear ache. The medical establishment is so ignorant of the function of normal flora of the upper respiratory tract that they never even saw serotype replacement coming when they began vaccinating children against certain bacteria that reside in the URT. They generally have no idea how the human body works as a whole, instead reducing each bit of it to a small part that they seem sure is unrelated to all the other small parts. Old thread, I know, but I was looking for something else and stumbled across this. I think the premise that it's always better to see an MD because cellular biologists understand cells just doesn't hold water. Yes, cellular biologists understand some things (not all!!!) about human cells. We aren't just a collection of cells, though, and your prescription drugs aren't only affecting a few cells here and there. The fact that cellular biologists understand cells in no way implies that *anyone* has a good grip on all the complex interactions that take place within a body that is ill or injured and all the additional complex interactions that take place within that body when drugs are added to the mix. Sometimes prescription drugs will be better. Sometimes they won't, cellular biologists' understanding of human cells notwithstanding....See MoreProposed Science Fair project for 5th grader
Comments (14)"One last thing is for the student to know why their experiment is important in the real world." One of my problems with the original hypothesis of which kitchen scraps would a worm prefer is how that makes a difference. It's not practical to separate food scraps into separate components. You might show that worms prefer watermelon rinds to beans but have you ever heard anyone complain about the amount of watermelon rinds causing problems at the landfill even after the 4th of July picnic? In this world of 'going green', I think I'd look at items that do present problems at the landfill but should not. A recycling company wants the easy to recycle stuff like newspaper, magazines, junkmail and old telephone books. Even in our city where we now have an active recycling initiative for paper and plastic we have things that are routinely sent to the landfill. A couple things come to mind. One is the papertowels from a restaurant or airport restroom. You could probably even get the information from the airport to compute the tonnage of waste paper they deal with. Another is disposable diapers -even though human waste is probably not something I would think a young child should be exposed to. And I'm not sure how well the worms can handle decomposing diapers anyway. A better choice would be lawn scraps. Particularly now that this is the time of year people will sending tons to the landfill instead of composting it themselves. You could even separate the lawn refuse into pure grass clippings vs chipped shrubbery scraps. I am aware that these will heat up and all that but you can do a week of precomposting them all after innoculating them with a measured amount of casting tea before adding the worms. The experiment would then not be a preference study but rather one of efficiency. Perhaps a mixture as another variable. After a specified time, sift the vermicompost for castings and compare with unprocessed material. You can do both bulk and weight comparisons....See MoreResearch project: How to recycle toilet paper ... (need help)
Comments (14)In Korea, almost 50 years ago, nearly everyone lived in single-family homes, usually each in a walled compound. Every home, including city ones, had a latrine in a small shed out back, a hole in the ground, over which one squatted to do one's business. Without contacting the facility: orientals think our habit of having multiple persons' rear ends (serially) touching the facility quite distasteful - as well as unhygienic in the extreme. Only a very few newspapers came into the average village, were passed from hand to hand for reading (reused), and then again for final use after the news had staled (recycled). No problem with surplus used newspapers. Entrepreneurs trundled ox-carts into town and charged householders a fee to empty their latrines, dipping the product with dried half-gourds on a stick, then pouring it into wooden tanks (which were much more durable than steel), which all the foreign community called "honey buckets". They hauled the loads out to the nearby farms, sold the product to the farmers to enrich their fields and scattered it immediately on the land - without composting. We were cautioned not to eat raw vegetables without thorough cleansing, with green ones to be used uncooked washed in water to which we'd added a chemical, as roundworm infestation was almost universal. Something like a third of the population were farmers in those days - with each farmer's holding being something like 3 acres. Many local farmers had been displaced to build military barracks for both Korean and a number of international brigades, airfields, etc. (including Prisoner of War camps which held many thousands of detainees). Refugees mostly had to scrounge a location wherever they could find it - a shack built of scraps over an open drain, high on mountainsides on unclaimed land, etc. So refugees who'd been farmers found it impossible to obtain land to work. In wartime, many businesses, industry and commerce were closed down, so it was very difficult also for non-farmers to find employment. Huge changes have taken place in Korea since those days. By the way - it's important for us to help the Afghans get back on their feet: they've known nothing but destructive war for a couple of generations - and (unlike the Iraqis) have few resources to pay for the rebuilding. By the way, we Canadians have a major lesson to learn from the Koreans - how to live next door to big neighbour(s) for centuries, without getting eaten. I hope that you're all enjoying a summer which adds some new polished facets to the diamond of your being. joyful guy...See MoreResearch Paper
