A study being released today finds that bisphenol A, a chemical widely used to make plastic and suspected of causing cancer, stays in the body much longer than previously thought.
The findings are significant because the longer the chemical lingers in the body, the greater chance it has of doing harm, scientists say.
Researchers from the University of Rochester in New York also say the chemical may get into the body from sources such as plastic Read the rest of this entry »

CHICAGO (AP) — A new study from Italy adds to a mountain of evidence that a mercury-based preservative once used in many vaccines doesn’t hurt children, offering more reassurance to parents.
In the early 1990s, thousands of healthy Italian babies in a study of whooping cough vaccines got two different amounts of the preservative thimerosal (pronounced thih-MEHR’-uh-sawl) from all their routine shots.

Doctors have known that some children and adolescents taking stimulant medications for attention deficit hyperactivity disorder experience psychiatric symptoms from the drugs, such as hallucinations, hearing voices, paranoia and mania.

Could our mother’s diet at the time we are conceived set the course for our future health? This intriguing question is at the heart of a new study based on an “experiment of nature” being conducted by Wellcome Trust-funded researchers. We inherit our DNA – the genetic blueprint that determines our make-up – from our parents: 50% of our DNA from our mothers and 50% from our fathers.

Newswise — A recent Northeastern University study has shown, for the first time, the effect of individual genes on the fitness of a marine species at the ecosystem level. Using his innovative computer simulation model, engineering professor Ferdi Hellweger found that eliminating photosynthesis genes from viruses that attack important marine photosynthetic bacterial organisms will negatively impact the fitness of these viruses, ultimately killing Read the rest of this entry »
