Study Shows Electrical Fields Influence Brain Activity

Neuronal activity is measured by EEG. Now it appears that electrical fields influence behavior of brain cells.
Most scientists have viewed electrical fields within the brain as the simple byproducts of neuronal activity. However, Yale scientists report in the July 15 issue of the journal Neuron that electrical fields can also influence the activity of brain cells.

The finding helps explain why techniques that influence electrical fields such as transcranial magnetic stimulation and deep brain stimulation are effective for the treatment of various neurological disorders, including depression. The study also "raises many questions about the possible effects of electrical fields, such as power lines and cell phones, in which we immerse ourselves," said David McCormick, the Dorys McConnell Duberg Professor of Neurobiology at Yale School of Medicine, a researcher of the Kavli Institute of Neuroscience and senior author of the study.

The chemical process that triggers tiny charges in the membranes of neurons causes much of the brain's electrical activity. Electroencephalograms, or EEGs, detect these fluctuations when they occur in large numbers of neurons together. These internal electrical signals contain information about certain cognitive and behavioral states but, until now, it had not been shown whether they actually change the activity of the brain itself.

Tainted Cereal Exposes Soggy Food-Safety System

On June 25, Kellogg's issued a "voluntary recall" of 28 million boxes of its breakfast cereals, including Froot Loops, Apple Jacks, Corn Pops, and Honey Smacks. The company revealed it had detected an "uncharacteristic off-flavor and smell coming from the liner in the package" of the suspect cereal and warned of "possible temporary symptoms, including nausea and diarrhea" from eating it.

Before we plunge our spoon into this cereal bowl of trouble, let's ponder the enormity of the recall. A box of cereal contains about 12 servings. That means Kellogg's recalled enough cereal to serve breakfast to 336 million people - sufficient for every man, woman, and child in the United States, with more than enough left over for every single Mexico City resident.

My brain can barely fathom the enormity; I'm picturing a towering sugar-glazed mountain, a crazy-colored Everest of Froot Loops and Apple Jacks.

But what is the real cost of applying these products to your body?

If I were to tell you that your personal care products could be putting you at risk for hair and skin damage, immunological problems, damage to your eyes, and possibly even cancer, would you pay a little more attention to their ingredients?

The growing awareness of chemicals in the foods you eat has led many of you to begin reading labels. If you are doing this as part of your regular shopping routine, I commend you, and you will likely live longer for it.

Concern: The study suggests pregnant women should think about how many fizzy drinks they consume
Mothers-to-be who down cans of fizzy drink containing artificial sweeteners could be at greater risk of having a premature baby.

Research funded by the EU found a correlation between the amount of diet drink consumed and an early birth among the 60,000 women studied.

Many had switched from sugary drinks to those with artificial sweeteners believing they were a healthier option.

But this study suggests that drinks using sweeteners, such as aspartame, carried dangers for the unborn child.

Some British public health experts are now advising expectant mothers to avoid food and drink containing the chemicals.

Scientists discover how broccoli fights cancer
Scientists may have discovered why eating broccoli seems to reduce the chance of developing prostate cancer.

Broccoli has been hailed as a 'superfood' after several studies suggested it had anti-cancer properties.

Now scientists have identified a chemical in the vegetable which interact with genes involved in cancer development.

Why is Drug Company with 50 Years of Proven Safety Violations Using Taxpayer Money to Make the Next Generation Flu Vaccine?

One of the more dangerous companies with a recurrent history of life threatening recalls is now in commissioned by government to make a new vaccine.

But can you really trust Baxter to produce a safe flu vaccine?

Baxter has a decades-long history of making mistakes that have led to recalls, lawsuits, and even deaths. So what guarantees do we have that they can produce a safe vaccine using a novel method?

As recently as May 18, a Baxter partner, Halozyme Therapeutics, publicly questioned the quality and capabilities of Baxter's manufacturing processes, when flake-like particles were discovered in a product that Baxter packages for Halozyme.

That product, Hylenex, which is used with an injected drug that helps rehydrate sick children, was recalled on May 17 after the contamination was discovered.

Viagra pills made by Pfizer. Pfizer, the world's biggest drug maker, said Tuesday it would eliminate 6,000 jobs worldwide as it restructures manufacturing after buying smaller rival Wyeth last year.
To say that Pfizer has been accused of wrongdoing is like saying BP had an oil spill.

The drug company Pfizer is best known for Lipitor, a drug that brings cholesterol down and Viagra, a drug that brings other things up.

But the "world's largest research-based pharmaceutical company" which sits between Goldman Sachs and Marathon Oil on the Fortune 500, is also closely associated with a seemingly never-ending series of scandals.

To say Pfizer's been accused of wrongdoing is like saying BP had an oil spill. Other drug companies have a portfolio of products, Pfizer has a portfolio of scandals including, but not limited to, Chantix, Lipitor, Viagra, Geodon, Trovan, Bextra, Celebrex, Lyrica, Zoloft, Halcion and drugs for osteoarthritis, Parkinson's disease, kidney transplants and leukemia.

Junk Food Mountain: The Astonishing Amount of Rubbish One Child Eats Every Year

Here we've amassed the average amount of typical snacks, fast food and treats eaten by children between the ages of four and ten in just one year. Scroll down for a breakdown of each food category
This shocking picture, with its piles of oven chips, mini rolls and tubs of ice cream, represents just how much junk food one child in the UK consumes in a year.

It is perhaps unsurprising then that today's children have been labeled the 'junk food generation', with a third of youngsters aged five to 13 already considered obese.

Despite this, the Conservatives have decided to axe the watchdog that was set up a decade ago to regulate the junk-food companies.

The Food Standards Agency was set up in 2000 to hold food firms to account after a series of scandals in which people had died from food-borne illnesses such as e.coli and CJD.

But today Health Secretary Andrew Lansley will unveil a long-awaited white paper containing plans to abolish it as part of a 'bonfire of quangos'.

Pseudoscience, front groups and smear campaigns against scientists questioning industrial agriculture are used to convince the public that chemical-ridden food is safe.

"You've probably heard of the 'Dirty Dozen' - a list of produce items identified by the Environmental Working Group that reportedly contain too many pesticide residues. I thought you might like to know about this webinar that provides perspective on pesticide residues," said an email sent by Elizabeth Pivonka, a registered dietitian who serves as the president and CEO for the Produce for Better Health Foundation.

Who Controls Our Children ? (Public Education Dumb Down Kids)

Mon, 12 Jul 2010 14:34 UTC
While parents, schools, provinces and states across North America bicker about the democratic process of running public schools, forces are manipulating education from behind the scenes. Major international players are reshaping public education to suit their own self-serving agendas, without regard for the wants of parents and the welfare of their children. This video lecture documents how today's educational system dumb down kids deliberately, making zombie-like people who don't ask any questions but just follow orders.
