Childhood chicken pox could affect oral health years later

CHICAGO (February 18, 2009) - You may recall as a child catching the itchy red rash, chicken pox. The unsightly infection was caused by the varicella zoster virus and was responsible for nearly 4 million cases each year, according to the Centers for Disease Control (CDC), until a vaccine introduce...

The viability of hydrogen transportation markets: Chicken or egg?

Darwin was wrong about the wild origin of the chicken

Charles Darwin maintained that the domesticated chicken derives from the red jungle fowl, but new research from Uppsala University now shows that the wild origins of the chicken are more complicated than that. The researchers mapped the genes that give most domesticated chickens yellow legs a...

Arsenic in chicken feed may pose health risks to humans, C&EN reports

Geoscientists follow arsenic from chicken feed to streambeds

What happened to the chicken when she crossed the road is less important that what happens to what she eats when it is used as fertilizer. Organic arsenic is fed to poultry to prevent bacterial infections and improve weight gain. A little bit of arsenic is taken up by the tissue and the majority ...

Hospitalizations because of chicken pox down dramatically since implementation of vaccine

Since the introduction of the varicella (chicken pox) vaccine in 1995, hospitalizations and doctor visits because of chicken pox have dropped dramatically, according to a study in the August 17 issue of JAMA.
