The magic of water...


Water Is Weird

Gregg Davidson, Christianity Today

If someone were to stop you on the street and ask you to name, on the spot, a naturally occurring substance that epitomized ordinary—something entirely lacking in strangeness—there is high probability that you would eventually say “water.” You might note, as an aside, that it is a very important ordinary substance, essential to life and refreshing to the parched, but nothing about water strikes you as being particularly odd.

But you would be wrong. I mean, really, really wrong. The behavior of water, at least when compared to other natural materials, is a bit bizarre. In particular, there are at least five different properties of water that, if you were stumbling upon it for the first time, might strike you as strange.

China: Fake It Till You Make It

Kal Raustiala and Christopher Sprigman, Foreign Affairs
No one knows for sure why some societies are more innovative than others. The United States is a highly inventive society, the source of a host of technologies—the airplane, the atomic bomb, the Internet—that have transformed the world. Modern China, by contrast, is frequently criticized for its widespread copying of foreign inventions and creative works. Once the home of gunpowder, printing, and other transformational inventions, China is today better known for its knockoffs of almost every imaginable product: cars, clothes, computers, fast food, movies, pharmaceuticals, even entire European villages. The United States gave the world the iPhone; China gave it the HiPhone—a cheap facsimile of a groundbreaking American gadget.

First-Ever Lifetime Feeding Study Finds Genetically Engineered Corn Causes Massive Tumors, Organ Damage, and Early Death



Dr. Mercola, September 
 The first-ever lifetime feeding study evaluating the health risks of genetically engineered foods was published online on September 19, and the results are troubling, to say the least. This new study joins a list of over 30 other animal studies showing toxic or allergenic problems with genetically engineered foods.
The study, published in the peer-reviewed journal Food and Chemical Toxicology, found that rats fed a type of genetically engineered corn that is prevalent in the US food supply for two years developed massive mammary tumors, kidney and liver damage, and other serious health problems.
The research was considered so “hot” that the work was done under strict secrecy. According to a French article in Le Nouvel Observateur, the researchers used encrypted emails, phone conversations were banned, and they even launched a decoy study to prevent sabotage.
According to the authors: “The health effects of a Roundup-tolerant genetically modified maize (from 11% in the diet), cultivated with or without Roundup, and Roundup alone (from 0.1ppb in water), were studied 2 years in rats. [Editors note: this level of Roundup is permitted in drinking water and GE crops in the US]
In females, all treated groups died 2-3 times more than controls, and more rapidly. This difference was visible in 3 male groups fed GMOs.
All results were hormone and sex dependent, and the pathological profiles were comparable. Females developed large mammary tumors almost always more often than and before controls, the pituitary was the second most disabled organ; the sex hormonal balance was modified by GMO and Roundup treatments.
In treated males, liver congestions and necrosis were 2.5-5.5 times higher… Marked and severe kidney nephropathies were also generally 1.3-2.3 greater. Males presented 4 times more large palpable tumors than controls, which occurred up to 600 days earlier.
Biochemistry data confirmed very significant kidney chronic deficiencies; for all treatments and both sexes, 76% of the altered parameters were kidney related. These results can be explained by the non linear endocrine-disrupting effects of Roundup, but also by the overexpression of the transgene in the GMO and its metabolic consequences.”
Does 10 percent or more of your diet consist of genetically engineered (GE) ingredients? At present, you can’t know for sure, since GE foods are not labeled in the US. But chances are, if you eat processed foods, your diet is chock full of genetically engineered ingredients you didn’t even know about.
The study in question includes photos and graphs. They really are not exaggerating when they say it caused massive tumors… They are huge! Some of the tumors weighed in at 25 percent of the rat’s total body weight. This is the most current and best evidence to date of the toxic effects of GE foods.
Rats only live a few years. Humans live around 80 years, so we will notice these effects in animals long before we see them in humans. The gigantic human lab experiment is only about 10 years old, so we are likely decades away from tabulating the human casualties. This is some of the strongest evidence to date that we need to avoid these foods.
Do we really wait 50 years to see what GE foods will do to human health and lifespan?
Related news also sheds light on the massive devastation brought on the environment by GE crops, and how soil destruction ends up affecting your health by decimating the nutrient content in the foods you eat.
In response to a scientific study that determined Western corn rootworms on two Illinois farms had developed resistance to Monsanto’s YieldGard corn, the US Environmental Protection Agency (EPA) made an admission about genetically engineered crops: Yes, there is “mounting evidence” that Monsanto’s insecticide-fighting corn is losing its effectiveness in the Midwest. Last year, resistant rootworms infested corn fields in Iowa, Illinois, Minnesota and Nebraska.
But YieldGard is just one of Monsanto’s problems. Roundup-Ready crops are creating super-resistant weeds that no longer respond to the herbicide. In fact, the problem is so bad that 20 million acres of cotton, soybean and corn have already been invaded by Roundup-resistant weeds.
Unfortunately, resistant weeds are not the only, or the worst, side effect of Roundup-Ready crops, genetically engineered to withstand otherwise lethal doses of glyphosate—the active ingredient in Roundup.
Mounting evidence tells us glyphosate itself may be far more dangerous than anyone ever suspected… Earlier this month, Purdue scientist Dr. Don Huber again spoke out about “the woes of GMO’s” and the inherent dangers of glyphosate in an article published by GM Watch.
“Corn used to be the healthiest plant you could grow. Now, multiple diseases, pests, and weak plants are the common denominator of ‘modern’ hybrids,” he writes.
“Over three decades ago we started the shift to a monochemical glyphosate herbicide program that was soon accompanied by glyphosate- and insect-resistant genetically engineered crops.
These two changes in agricultural practices—the excessive application of a strong essential mineral chelating, endocrine-disrupting chemical for weed control and the genetically engineered production of new toxins in our food crops—was accompanied by abandonment of years of scientific research based on the scientific precautionary principle. We substituted a philosophical ‘substantially equivalent,’ a new term coined to avoid accountability for the lack of understanding of consequences of our new activities, for science.”
Dr. Huber commented, “Future historians may well look back upon our time and write, not about how many pounds of pesticide we did or didn’t apply, but by how willing we are to sacrifice our children and future generations for this massive genetic engineering experiment that is based on flawed science and failed promises just to benefit the bottom line of a commercial enterprise.”

Foes of Modified Corn Find Support in a Study



By Andrew Pollack, NY Times
Rats fed either genetically engineered corn or the herbicide Roundup had an increased risk of developing tumors, suffering organ damage and dying prematurely, according to a new study that was immediately swept up into the furor surrounding crop biotechnology when it was released Wednesday.
The study, conducted by a prominent opponent of genetically engineered crops, was immediately criticized by some other scientists, who said the methods were flawed and that other research had not found similar problems.
But in California, proponents of a ballot measure that would require genetically modified foods to be labeled immediately seized on the study as support for their cause. The French government ordered a review of the findings, saying they could possibly result in the suspension of European imports of that type of corn.
The study, which is being published in the peer-reviewed journal Food and Chemical Toxicology, was led by Gilles-Eric Séralini at the University of Caen in France. He is also a leader of the Committee for Independent Research and Information on Genetic Engineering, which sponsored the research.
The study followed 200 rats for two years, essentially their entire lives, far longer than the typical 90-day feeding studies used to win regulatory approval of genetically engineered crops in some countries. While there have been some other long-term studies, none has involved as many animals or as many detailed measurements.
“The results were really alarming,” Dr. Séralini said in a telephone news conference conducted by an organization in Britain opposed to genetically modified crops. He said that the tumors did not develop until well after 90 days, meaning they might have been missed by shorter studies.
The rats in the study were split into 10 groups, each containing 10 male and 10 female rats. Six of the groups were fed different amounts of a corn developed by Monsanto to be resistant to the herbicide Roundup. In some cases the corn had been sprayed in the field with Roundup.
Three other groups were given different doses of Roundup in their drinking water, with the lowest dose corresponding to what might be found in tap water in the United States, the authors said.
The 10th group, the control, was fed nonengineered corn and plain water.
The study found that in groups that ate the engineered corn, up to 50 percent of the males and 70 percent of the females died before they would have from normal aging, compared with 30 percent of the males and 20 percent of the females in the control group.
Some 50 to 80 percent of the female rats developed tumors compared with only 30 percent of the controls. And there were several times as many cases of liver and kidney injury in the exposed rats.
Some critics pointed out that the new findings contradicted other studies. One review of long-term studies, published earlier this year, concluded that those studies did not present evidence of health hazards.
Dr. Chassy said that people and livestock had been eating genetically modified grains for years without evidence of the high death rates and tumors in the study. “Curious that no increase in tumor incidence has been reported in animals eating large amounts of such grains,” he said.
Monsanto, in a statement, said it would review the study, but that other studies had confirmed the safety of its crops.

Big Shit: Information in mankind's intestines measures 60 thousand times the length of the universe!


by F.G.Helmke 

Figure it out yourself: The information for one microbe written on paper would take a distance about from here to the moon

Distance to the moon: 380 000 km (38 x 104km)
Number of microbes in the body: 100 trillion (10x1012)
Information for 100 trillion microbes written on paper:
100 trillion x 380 000 km =
10 x 10 12 x 38 x 10 4 = 38 x 10 17 km
(1 light year equals 10 13 km)
38 x 10 17 : 10 13 =
= 380 000 light years

The information in the DNA of all the microbes of just one person written on paper would take a paper 380 000 light years long.

World population:about 7 billion people
7 billion x 380 000 light years = 2 700 000 billion light years
Total information in mankind’s intestines written on paper: 2 700 000 billion light years 

Size of the universe: 45 billion light years
Length of the information divided by the length of the universe:
2 700 000 billion km  : 45 billion km = 60 000

Result: If the information in the intestines of mankind were written on paper you would need a paper about 60 000 times the length of the universe.

Even if these numbers are not 100% exact, they are still very impressive. Do you really believe that such a size of information can have happened by chance, or might there be some intelligent design? Remember, these are just the simplest creatures!  Panda Bears and Human Beings have thousands of trillions times more information stored in their genes…

The incredible amount of oil burned unto today. Deadly experiments part two


by F.G.Helmke
 
Can you kill the Earth "by burning an oil lamp?" Let’s calculate:
Total oil produced up to date: 100 billion tons
One ton is one billion milligrams
That’s one hundred billion billions of milligrams of oil produced
(100 000 000 000 000 000 000 mg)

The atmosphere of the Earth: 4 billion cubic kilometers (at sea level conditions)
One cubic kilometer is one billion cubic meters
So the atmosphere contains four billion billions of cubic meters of air
(4 000 000 000 000 000 000 m³)

100 billion billions of milligrams divided by 4 billion billions of cubic meters 
That’s  25 milligrams of oil burned per cubic meter of air in our atmosphere.
100 000 000 000 000 000 000 mg
:   4 000 000 000 000 000 000 m³
= 25 mg/m³

  Now let’s do the following experiment: Get a one cubic meter cardboard box. Put you head inside and seal it. Take a syringe with 25 mg or about 33 ml of crude oil, put it into an oil lamp and light it. If you survive, keep on driving your car! If not, be sure you go to heaven! When you arrive there you’d better have a good apology why you allowed this to happen your planet!

Sugar can make you dumb, US scientists warn


 AFP 
Eating too much sugar can eat away at your brainpower, according to US scientists who published a study Tuesday showing how a steady diet of high-fructose corn syrup sapped lab rats' memories.
Researchers at the University of California Los Angeles (UCLA) fed two groups of rats a solution containing high-fructose corn syrup -- a common ingredient in processed foods -- as drinking water for six weeks.
One group of rats was supplemented with brain-boosting omega-3 fatty acids in the form of flaxseed oil and docosahexaenoic acid (DHA), while the other group was not.
Before the sugar drinks began, the rats were enrolled in a five-day training session in a complicated maze. After six weeks on the sweet solution, the rats were then placed back in the maze to see how they fared.
"The DHA-deprived animals were slower, and their brains showed a decline in synaptic activity," said Fernando Gomez-Pinilla, a professor of neurosurgery at the David Geffen School of Medicine at UCLA.
"Their brain cells had trouble signaling each other, disrupting the rats' ability to think clearly and recall the route they'd learned six weeks earlier."
A closer look at the rat brains revealed that those who were not fed DHA supplements had also developed signs of resistance to insulin, a hormone that controls blood sugar and regulates brain function.
"Because insulin can penetrate the blood-brain barrier, the hormone may signal neurons to trigger reactions that disrupt learning and cause memory loss," Gomez-Pinilla said.
In other words, eating too much fructose could interfere with insulin's ability to regulate how cells use and store sugar, which is necessary for processing thoughts and emotions.
"Insulin is important in the body for controlling blood sugar, but it may play a different role in the brain, where insulin appears to disturb memory and learning," Gomez-Pinilla said.
"Our study shows that a high-fructose diet harms the brain as well as the body. This is something new."
High-fructose corn syrup is commonly found in soda, condiments, applesauce, baby food and other processed snacks.
The average American consumes more than 40 pounds (18 kilograms) of high-fructose corn syrup per year, according to the US Department of Agriculture.
While the study did not say what the equivalent might be for a human to consume as much high-fructose corn syrup as the rats did, researchers said it provides some evidence that metabolic syndrome can affect the mind as well as the body.
"Our findings illustrate that what you eat affects how you think," said Gomez-Pinilla.
"Eating a high-fructose diet over the long term alters your brain's ability to learn and remember information. But adding omega-3 fatty acids to your meals can help minimize the damage."
The study appeared in the Journal of Physiology.

Science Reveals Why We Brag So Much

By Robert Lee Hotz, WSJ 
Talking about ourselves—whether in a personal conversation or through social media sites like Facebook and Twitter—triggers the same sensation of pleasure in the brain as food or money, researchers reported Monday.
About 40% of everyday speech is devoted to telling others about what we feel or think. Now, through five brain imaging and behavioral experiments, Harvard University neuroscientists have uncovered the reason: It feels so rewarding, at the level of brain cells and synapses, that we can’t help sharing our thoughts.
“Self-disclosure is extra rewarding,” said Harvard neuroscientist Diana Tamir, who conducted the experiments with Harvard colleague Jason Mitchell. Their findings were published in the Proceedings of the National Academy of Sciences. “People were even willing to forgo money in order to talk about themselves,” Ms. Tamir said.
“It rings true to me,” said psychologist James Pennebaker at the University of Texas at Austin who studies how people handle secrets and self-disclosure, but was not involved in the project. “We love it if other people listen to us. Why else would you tweet?”

Unraveling how children become bilingual so easily


By Lauran Neergaard, Associated Press
WASHINGTON--The best time to learn a foreign language: Between birth and age 7.
New research is showing just how children's brains can become bilingual so easily, findings that scientists hope eventually could help the rest of us learn a new language a bit easier.
"We think the magic that kids apply to this learning situation, some of the principles, can be imported into learning programs for adults," says Dr. Patricia Kuhl of the University of Washington, who is part of an international team now trying to turn those lessons into more teachable technology.
Each language uses a unique set of sounds. Scientists now know babies are born with the ability to distinguish all of them, but that ability starts weakening even before they start talking, by the first birthday.
Kuhl offers an example: Japanese doesn't distinguish between the "L" and "R" sounds of English--"rake" and "lake" would sound the same. Her team proved that a 7-month-old in Tokyo and a 7-month-old in Seattle respond equally well to those different sounds. But by 11 months, the Japanese infant had lost a lot of that ability.
Time out--how do you test a baby? By tracking eye gaze. Make a fun toy appear on one side or the other whenever there's a particular sound. The baby quickly learns to look on that side whenever he or she hears a brand-new but similar sound. Noninvasive brain scans document how the brain is processing and imprinting language.
Mastering your dominant language gets in the way of learning a second, less familiar one, Kuhl's research suggests. The brain tunes out sounds that don't fit.
It's remarkable that babies being raised bilingual--by simply speaking to them in two languages--can learn both in the time it takes most babies to learn one.
On average, monolingual and bilingual babies start talking around age 1 and can say about 50 words by 18 months.
Italian researchers wondered why there wasn't a delay, and reported this month in the journal Science that being bilingual seems to make the brain more flexible.
The researchers tested 44 12-month-olds to see how they recognized three-syllable patterns--nonsense words, just to test sound learning. Sure enough, gaze-tracking showed the bilingual babies learned two kinds of patterns at the same time--like lo-ba-lo or lo-lo-ba--while the one-language babies learned only one, concluded Agnes Melinda Kovacs of Italy's International School for Advanced Studies.
While new language learning is easiest by age 7, the ability markedly declines after puberty.
"We're seeing the brain as more plastic and ready to create new circuits before than after puberty," Kuhl says. As an adult, "it's a totally different process.
You won't learn it in the same way. You won't become (as good as) a native speaker."
What might help people who missed their childhood window? Baby brains need personal interaction to soak in a new language--TV or CDs alone don't work. So researchers are improving the technology that adults tend to use for language learning, to make it more social and possibly tap brain circuitry that tots would use.
Recall that Japanese "L" and "R" difficulty? Kuhl and scientists at Tokyo Denki University and the University of Minnesota helped develop a computer language program that pictures people speaking in "motherese," the slow exaggeration of sounds that parents use with babies.
Japanese college students who'd had little exposure to spoken English underwent 12 sessions listening to exaggerated "Ls" and "Rs" while watching the computerized instructor's face pronounce English words. Brain scans--a hair dryer-looking device called MEG, for magnetoencephalography--that measure millisecond-by-millisecond activity showed the students could better distinguish between those alien English sounds. And they pronounced them better, too, the team reported in the journal NeuroImage.
"It's our very first, preliminary crude attempt but the gains were phenomenal," says Kuhl.
But she'd rather see parents follow biology and expose youngsters early. If you speak a second language, speak it at home. Or find a play group or caregiver where your child can hear another language regularly.
"You'll be surprised," Kuhl says. "They do seem to pick it up like sponges."
