Genetically Engineered Crops May Produce Herbicide Inside Our Intestines

Pioneer Hi-Bred's website boasts that their genetically modified (GM) Liberty Link corn survives doses of Liberty herbicide, which would normally kill corn. The reason, they say, is that the herbicide becomes "inactive in the corn plant." They fail to reveal, however, that after you eat the GM corn, some inactive herbicide may become reactivated inside your gut and cause a toxic reaction. In addition, a gene that was inserted into the corn might transfer into the DNA of your gut bacteria, producing long-term effects. These are just a couple of the many potential side-effects of GM crops that critics say put the public at risk.

iPods 'mess with pacemakers'

iPods have joined late-opening restaurants and children playing on old people's lawns on the list of things that can make pacemakers go haywire.

A new study, presented today to a meeting of heart specialists by a 17-year-old high school student, suggests that the music-playing device can interfere with the electromagnetic equipment in implanted pacemakers.

Reuters reports 100 pacemaker patients (with a mean age of 77) were examined in the study.

Holding the iPod just two inches away from their chests for 5 to 10 seconds was enough to cause electrical interference half the time. In some cases, iShenanigans could be detected as far as 18 inches away. The interference usually just caused the equipment to misread the heart's pacing, but one case caused the pacemaker to stop working entirely.

Docs Change the Way They Think About Death

Consider someone who has just died of a heart attack. His organs are intact, he hasn't lost blood. All that's happened is his heart has stopped beating - the definition of "clinical death" - and his brain has shut down to conserve oxygen. But what has actually died?

Study casts new doubts on HPV vaccine

New data on the controversial HPV vaccine designed to prevent cervical cancer have raised serious questions about its efficacy, researchers reported today, potentially undercutting the efforts in many states to make vaccination mandatory.

Study suggests cancer risk from depleted uranium

Depleted uranium, which is used in armour-piercing ammunition, causes widespread damage to DNA which could lead to lung cancer, according to a study of the metal's effects on human lung cells. The study adds to growing evidence that DU causes health problems on battlefields long after hostilities have ceased.

Help Wanted: Human Guinea Pigs

If you've ever wondered why we so rarely hear of drug trials going awry in the United States, Sonia Shah, author of The Body Hunters: Testing New Drugs on the World's Poorest Patients (The New Press, 2006), has the unattractive answer: we "offshore" the drug trials to developing nations and to those who simply can't afford to say "anywhere but here."

Meditation Sharpens the Mind

Three months of intense training in a form of meditation known as "insight" in Sanskrit can sharpen a person's brain enough to help them notice details they might otherwise miss.

Toxic World Trade Center dust linked to lung disease in rescue workers

Rescue workers and firefighters in New York City contracted a serious lung-scarring disease called sarcoidosis at a much higher rate after the Sept. 11 attacks than before, said a study that is the first to link the disease to exposure to toxic dust at Ground Zero.

The study, published by nine doctors including the medical officer monitoring city firefighters, Dr. David Prezant, found that firefighters and rescue workers contracted sarcoidosis in the year after Sept. 11, 2001, at a rate more than five times higher than the years before the attacks.

New fears over additives in children's food

Potential link to behaviour problems prompts advice to parents over diet
Food safety experts have advised parents to eliminate a series of additives from their children's diet while they await the publication of a new study that is understood to link these ingredients to behaviour problems in youngsters.

Stress of deployment increases risk of child abuse, neglect in military families, UNC study shows

Rates of abuse and neglect of young children in military families in Texas has doubled since October 2002, a University of North Carolina at Chapel Hill study shows, raising concerns about the impact of deployment on military personnel and their families across the country.

The study, published in the May 15, 2007 issue of the American Journal of Epidemiology, was designed by UNC School of Public Health researchers to measure the impact of the 9/11 terrorist attacks on military and non-military families. The researchers chose to study Texas because of the large military population there and the availability of data.

Researchers found that prior to October 2002, rate of abuse and neglect - called maltreatment - was slightly higher among non-military families compared to military families. However, after the U.S. started sending larger numbers of troops to Afghanistan and Iraq in 2003, rates of abuse and neglect in military families far outpaced the rates among non-military families. Military files indicate more troops were deployed and fewer returned home in 2003.

In addition, the rate of occurrence of substantiated maltreatment in military families was twice as high in the period after October 2002 compared with the period prior to that date. During the same period, the rate of substantiated child abuse and neglect was relatively stable for non-military families, said Danielle Rentz, Ph.D., lead author of the study, which was part of her doctoral dissertation at the UNC School of Public Health.
