Hospitals and airplanes ban the use of cell phones, because their electromagnetic transmissions can interfere with sensitive electrical devices. Could the brain also fall into that category? Of course, all our thoughts, sensations and actions arise from bioelectricity generated by neurons and transmitted through complex neural circuits inside our skull. Electrical signals between neurons generate electric fields that radiate out of brain tissue as electrical waves that can be picked up by electrodes touching a person's scalp. Measurements of such brainwaves in EEGs provide powerful insight into brain function and a valuable diagnostic tool for doctors. Indeed, so fundamental are brainwaves to the internal workings of the mind, they have become the ultimate, legal definition drawing the line between life and death.
Brainwaves change with a healthy person's conscious and unconscious mental activity and state of arousal. But scientists can do more with brainwaves than just listen in on the brain at work-they can selectively control brain function by transcranial magnetic stimulation (TMS). This technique uses powerful pulses of electromagnetic radiation beamed into a person's brain to jam or excite particular brain circuits.

Almost one in six cases of depression among working Victorians are caused by job stress. This means more than 21,000 cases of preventable depression are caused by job stress each year, a new University of Melbourne study shows.
Stressful working conditions in this study were defined as a combination of high job demands and low control over how the job gets done (or 'job strain').

Uganda has the highest rate of post-traumatic stress and depression ever recorded, following extremely high of civilian exposure to violence and poor healthcare, a study published in BMC Psychiatry says today.
Health officials from Greece, Israel and Cyprus met in Miami on Thursday to discuss a plan to share transplant organs and overcome the challenge of having small populations and low donation rates.
An informal pooling of medical resources _ organs as well as specialist surgeons _ has existed among them for several years. But the Mediterranean nations are now looking to formalize the relationship, make it more efficient and consistent, and establish a Web-based donor registry to facilitate it, officials said.

Many people haven't heard of Monsanto before. But I guarantee after reading this you will remember it.
Monsanto, the chemical giant, has created some of the most toxic substances whose residues have creates the most polluted places on our earth (Barlett, 2008). With that in mind, it is scary to think they have infiltrated the worlds agriculture with genetically modified seeds and mafia like tactics.
Monsanto has produced Genetically modified soybeans, corn, canola, and cotton. More are in the works including sugar beets, and alfalfa. They are also branching out with a strangle hold on the milk industry marketing artificial growth hormones that increase milk production in dairy cow. Monsanto is taking aggressive steps to put those who do not use growth hormones out of business (Barlett, 2008).
A recent New York Times/CBS poll bears good news for ecopreneurs in the food industry. Fifty-Three percent of consumers said they would not buy genetically modified food. Unfortunately, there's no way to tell the difference between Frankenfoods and the real thing.
A new CBS News poll found that 87% of consumers would like GMO ingredients to be labeled, just as they are in Europe, Japan and Australia. Yet the U.S. Congress has never even held a vote on the issue, to give shoppers the opportunity to exercise their most basic right - to make a choice.Once again, labeling decisions made by the FDA and USDA, influenced heavily by big agriculture are keeping consumers from understanding what is in their food. The FDA's position is: GMOs are the "substantial equivalent" of conventional crops and so does not require "disclosure of genetic engineering techniques...on the label."Of course, there's an explanation for that.
Robert Brackett is spokesman for the Grocery Manufacturers of America.
"I think that consumers have that information available to them if they want to look for it," says Brackett, "You can find it on websites. You can go directly to the manufacturer."
Eighteen per cent of school children who took part in two health surveys carried out a year apart admitted they had eating problems, according to research published in the latest Journal of Advanced Nursing.
Thirteen per cent admitted eating problems in either the first or second survey and a further five per cent reported problems in both surveys.
Students who had ongoing eating problems were more likely to report multiple psychological problems and health complaints.
"For example we noticed that students who reported suffering from anxiety earlier in adolescence were 20 times more likely to have ongoing eating problems" says Lea Hautala from the Adolescent Psychiatry Clinic at the University of Turku, Finland.
"And teenagers who were dissatisfied with their appearance only had recurring eating problems if they also reported anxiety earlier in adolescence."

You may not be what you eat after all.
A new study shows that increased eating does not necessarily lead to increased fat. The finding in the much-studied roundworm opens the possibility of identifying new targets for drugs to control weight, the researchers say.
The discovery reveals that the neurotransmitter serotonin, already known to control appetite and fat build-up, actually does so through two separate signaling channels. One set of signals regulates feeding, and a separate set of signals regulates fat metabolism. The worm, known scientifically as Caenorhabdtis elegans, shares half of its genes with humans and is often a predictor of human traits.
The signaling pathways are composed of a series of molecular events triggered by neurons in the brain that ultimately "instruct" the body to burn or store fat.
If the "separate-channel" mechanism is also found in humans, weight-loss drugs might be developed to attack just the fat-deposition channel rather than the hunger-dampening pathway that has met with limited success, says Kaveh Ashrafi, PhD, assistant professor of physiology at UCSF and senior author on the scientific paper reporting the study.

Do you ever get the feeling that your doctor doesn't know what he's doing? Well, you are probably right. There is little or no evidence that today's $2 trillion-dollar medical system works any better than various other alternatives. Whether you have diabetes, heart trouble, back pain or cancer, this judgment applies. If you are contemplating surgery, you should know that the orthodox disease establishment doctors have little clue about the success rates for the procedures they endorse.
Over recent years, we in the U.S. have become accustomed to the seemingly never-ending parade of prescription drug commercials on television. It's surprising to learn that the only two places advertising of this kind is legal is in the United States and New Zealand.
Would it surprise you to learn that the pharmaceutical industry not only targets Americans directly in this fashion, but also allocates approximately $25,000 per doctor per year? With the help of today's technology, a pharmaceutical representative can know exactly how many prescriptions a doctor has written and for what drugs. Obviously, this information allows the industry to target certain physicians that fit certain profiles.

Comment: Amazing that despite all the evidence presented throughout the article that cell phones pose a grave danger to our mental and physical health, last paragraph offers a calming and damage control message: "Relax people, so what if cell phones have an ability to alter your brain chemistry and function? We assure you that such interesting fact won't cause any serious harm, all the more so, won't be used for insidious purposes. No way!"
Well, consider the following:
