Scientists Discover New Technique to Remove Fluoride from Drinking Water. Written by Andrew Puhanic AROUND the world, it is estimated that tens of millions of people are affected by both dental and skeletal fluorosis.
In many cases, it is the addition of fluoride into drinking water supplies by governments that is the primary cause of both dental and skeletal fluorosis. Common techniques used for defluoridation are coagulation-precipitation, membrane process and ion exchange. The problem with these three techniques is that they are either too expensive or they further pollute the water.
Researchers from the National University of Sciences and Technology in Pakistan have discovered an effective method to removefluoride from drinking water that is less expensive than conventional filtration processes and is safe to use. Modified immobilized activated alumina (MIAA) was added to water that was tainted with fluoride and then analysis was conducted to evaluate the quantity of fluoride that was removed from the water.

The origins of these struggles are fairly clear.
The largest crisis of capitalism since the Great Depression continues today. States bailed out deregulated banks using trillions in public funds, and now people are left to suffer. Some teachers in Greece bring toilet paper from their homes because schools can no longer afford basic supplies. People are struggling for basic human dignity. And for many in the world, resistance is not a moral imperative. The latest crisis of capital has exacerbated these trends, with the potential of increasing infant mortality rates by 400,000 per year, according to a United Nations report. As a visible gauge of this crisis, the Greater London Pensioners’ Association recently held a demonstration with an infuriating, saddening demand: “No More Deaths from Fuel Poverty.”
If people in the UK believe in democracy, and most invariably do, than the blame rests squarely on public shoulders. This is not simply a global humanitarian crisis. Parents decry new Carroll schools palm scanner. Instead of paying for their lunches with crumpled dollar bills and loose change, students in Carroll County schools are having their palms scanned in a new check-out system — raising concerns from some parents that their children's privacy is being violated.
The county is one of the first localities in Maryland to use the PalmSecure system, in which children from kindergarten to 12th grade place their hands above an infrared scanner. It identifies unique palm and vein patterns, and converts the image into an encrypted numeric algorithm that records a sale. Though the school system does not store those images, some parents have complained about the implications of having their children's hands scanned. About 20 percent of parents have declined to participate in the program, said supervisor of food services Karen Sarno. "I didn't appreciate how they handled it," said Mike Richmond, who has two children at Westminster's Cranberry Elementary School.

Rupert Sheldrake challenges the mechanistic dogma of contemporary mainstream science. He has recently released a new book, Science Set Free: 10 Paths to New Discovery, which addresses the ideas that have become dogmas in modern scientific thought, exposes their weaknesses, and offers intriguing solutions for a way forward. Gabriel Roberts: Dr. Sheldrake, you are known for raising the public's awareness about morphic fields.
What are they and what's the evidence to support them? Universe, Brain, Internet: Growth Patterns Similar In Large & Small Networks, Computer Study Suggests - The Huffington Post. By: Tia Ghose, LiveScience Staff Writer Published: 11/26/2012 04:13 PM EST on LiveScience The universe may grow like a giant brain, according to a new computer simulation.
The results, published Nov.16 in the journal Nature's Scientific Reports, suggest that some undiscovered, fundamental laws may govern the growth of systems large and small, from the electrical firing between brain cells and growth of social networks to the expansion of galaxies. "Natural growth dynamics are the same for different real networks, like the Internet or the brain or social networks," said study co-author Dmitri Krioukov, a physicist at the University of California San Diego. The new study suggests a single fundamental law of nature may govern these networks, said physicist Kevin Bassler of the University of Houston, who was not involved in the study.
[What's That? "At first blush they seem to be quite different systems, the question is, is there some kind of controlling laws can describe them? " Your-Argument-is-Irrelephant.gif 486×391 pixels.
