Before her last deployment, 31-year-old Staff Sergeant Danielle Nienajadlo passed her Army physical with flying colors. So when she started having health problems several weeks after arriving at Balad Air Base in Iraq, no one knew what to make of her symptoms: headaches that kept her awake; unexplained bruises all over her body; an open sore on her back that wouldn't heal; vomiting and weight loss. In July 2008, after three miserable months, Nienajadlo checked into the base emergency room with a 104-degree fever.

She was sent to Walter Reed Army Medical Center and learned she had been diagnosed with acute myelogenous leukemia, a fast-progressing form of the disease. She told her doctors and her family she had felt fine until she started inhaling the oily black smoke that spewed out of the base's open-air trash-burning facility day and night. At times, the plume contained dioxins, some of which can cause the kind of cancer Nienajadlo had.

"She breathed in this gunk," says her mother, Lindsay Weidman. "She'd go back to the hooch at night to go to bed and cough up these black chunks."

As technology has played a bigger role in our lives, our skills in critical thinking and analysis have declined, while our visual skills have improved, according to research by Patricia Greenfield, UCLA distinguished professor of psychology and director of the Children's Digital Media Center, Los Angeles.

Learners have changed as a result of their exposure to technology, says Greenfield, who analyzed more than 50 studies on learning and technology, including research on multi-tasking and the use of computers, the Internet and video games. Her research was published this month in the journal Science.

Reading for pleasure, which has declined among young people in recent decades, enhances thinking and engages the imagination in a way that visual media such as video games and television do not, Greenfield said.

How much should schools use new media, versus older techniques such as reading and classroom discussion?

Apple juice certainly sounds healthy, doesn't it? It's a popular choice for many parents who serve it up as a healthy alternative to sugary drinks and sodas. But new research released by Florida's St. Petersburg Times newspaper suggests that apple juice may not be as healthy as we think. The paper commissioned independent testing on the most popular brands of apple juice sold nationwide and found that many brands contain levels of arsenic that have raised concerns for health experts and parents.

Are you tired and worn out?

Do you have sore muscles, fatigue, and brain fog?

If so, you might have metabolic burnout!

Imagine if you could find a way to tune up your metabolism, increase your energy levels, think clearly, and feel less achy.

Imagine if you could prevent diabetes, heart disease, Parkinson's disease, and dementia.

Imagine if you could heal fibromyalgia and chronic fatigue syndrome.

Imagine if you could get to the roots of aging, slow the whole process, and eliminate most age-related diseases.

These aren't just fantasies.

All these things are possible - if you give yourself a metabolic tune-up.

Dr. David Ayoub is a radiologist and a physician, and has become a specialist on the additives and preservatives used in vaccines. He was a presenter at the National Vaccine Information Center (NVIC) Conference in Washington D.C. last year.

Here he discusses the practice of using aluminum as an adjuvant, and why he believes aluminum may be far more toxic than thimerosal in vaccines.

The globe-spanning presence of wheat and its exalted status among secular and sacred institutions alike differentiates this food from all others presently enjoyed by humans. Yet the unparalleled rise of wheat as the very catalyst for the emergence of ancient civilization has not occurred without a great price. While wheat was the engine of civilization's expansion and was glorified as a "necessary food," both in the physical (staff of life) and spiritual sense (the body of Christ), those suffering from celiac disease are living testimony to the lesser known dark side of wheat. A study of celiac disease may help unlock the mystery of why modern man, who dines daily at the table of wheat, is the sickest animal yet to have arisen on this strange planet of ours.

The Celiac Iceberg

Celiac disease (CD) was once considered an extremely rare affliction, limited to individuals of European origin. Today, however, a growing number of studies¹ indicate that celiac disease is found throughout the US at a rate of up to 1 in every 133 persons, which is several orders of magnitude higher than previously estimated.

These findings have led researchers to visualize CD as an iceberg². The tip of the iceberg represents the relatively small number of the world's population whose gross presentation of clinical symptoms often leads to the diagnosis of celiac disease. This is the classical case of CD characterized by gastrointestinal symptoms, malabsorption and malnourishment. It is confirmed with the "gold standard" of an intestinal biopsy. The submerged middle portion of the iceberg is largely invisible to classical clinical diagnosis, but not to modern serological screening methods in the form of antibody testing³. This middle portion is composed of asymptomatic and latent celiac disease as well as "out of the intestine" varieties of wheat intolerance. Finally, at the base of this massive iceberg sits approximately 20-30% of the world's population - those who have been found to carry the HLA-DQ locus of genetic susceptibility to celiac disease on chromosome 6.⁴

The "Celiac Iceberg" may not simply illustrate the problems and issues associated with diagnosis and disease prevalence, but may represent the need for a paradigm shift in how we view both CD and wheat consumption among non-CD populations.

First let us address the traditional view of CD as a rare, but clinically distinct species of genetically-determined disease, which I believe is now running itself aground upon the emerging, post-Genomic perspective, whose implications for understanding and treating disease are Titanic in proportion.

High doses of lead have for some time been linked to chronic kidney damage. But a recent study out of Johns Hopkins Children's Center found that even small levels of lead exposure may be damaging to children's kidneys.

The report, published January in the Archives of Internal Medicine, looked at the records of 769 healthy youth ages 12 to 20 with average blood lead levels of 1.5 micrograms per deciliter (well below the 10 microgram "threshold" of concern per the Centers for Disease Control and Prevention).

Researchers found that children with levels of just 2.9 micrograms per deciliters had worse kidney function than those with lower levels. With each doubling of lead levels, the filtration capacity dropped.

It is just the latest study in a growing body of research finding that lead levels well below the CDC's threshold may have a detrimental impact on children's health.

New study shows that self-control can be automatically, unconsciously bolstered by abstract thinking.

Wouldn't it be great if we could just spontaneously and automatically exercise self-control, without all that painful back-and-forth battle with ourselves?

Just automatically resist that cake and choose the apple; or suddenly find ourselves out jogging without resorting to self-blackmail; or effortlessly write more articles for our websites (bit of a personal one there!).

Unfortunately so often temptation wins. And experiments show that when we are run down from exercising self-discipline all day, we become even more likely to give in to temptation.

Extreme obesity is affecting more children at younger ages, with 12 percent of black teenage girls, 11.2 percent of Hispanic teenage boys, 7.3 percent of boys and 5.5 percent of girls now classified as extremely obese, according to a Kaiser Permanente study of 710,949 children and teens that appears online in the Journal of Pediatrics.

This is the first study to provide a snapshot of the prevalence of extreme obesity in a contemporary cohort of children ages 2 -- 19 years from a large racially and ethnically diverse population using the recent 2009 U.S. Centers for Disease Control and Prevention extreme obesity definition. Previous research was based on recent National Health and Nutrition Examination Survey (NHANES) data and included information on obesity but not extreme obesity.

"Children who are extremely obese may continue to be extremely obese as adults, and all the health problems associated with obesity are in these children's futures. Without major lifestyle changes, these kids face a 10 to 20 years shorter life span and will develop health problems in their twenties that we typically see in 40 -- 60 year olds," said study lead author Corinna Koebnick, PhD, a research scientist at the Kaiser Permanente Southern California's Department of Research and Evaluation in Pasadena, Calif. "For example, children who are extremely obese are at higher risk for heart disease, type 2 diabetes, fatty liver disease and joint problems, just to name a few."

Chronic feelings of loneliness take a toll on blood pressure over time, causing a marked increase after four years, according to a new study at the University of Chicago.

A new study shows, for the first time, a direct relation between loneliness and larger increases in blood pressure four years later -- a link that is independent of age and other factors that could cause blood pressure to rise, including body-mass index, smoking, alcohol use and demographic differences such as race and income.

The researchers also looked at the possibility that depression and stress might account for the increase but found that those factors did not fully explain the increase in blood pressure among lonely people 50 years and older.

"Loneliness behaved as though it is a unique health-risk factor in its own right," wrote researcher Louise Hawkley in an article published in the current issue of the journal Psychology and Aging.
