November 30, 2007 05:49 PM -

PORTLAND, Maine - USDA scientists recently concluded that eating Wild Blueberries and other antioxidant-rich foods at every meal helps prevent oxidative stress. (Journal of the American College of Nutrition, Vol. 26, No. 2, 170-181, 2007) This study advances antioxidant research by moving beyond the measurement of antioxidants in foods to actual examination of the performance of specific fruits against oxidative stress in the body. Oxidative stress is linked to chronic diseases and aging.

 

 

 

 

 

Stem cell innovators find a way to cut out cancer
November 30, 2007 05:43 PM - By Maggie Fox, Health and Science Editor, Reuters

WASHINGTON (Reuters) - Researchers who figured out how to make valued embryonic stem cells out of ordinary skin cells said on Friday they had found a way to cut one cancer-causing ingredient out of the mix.

But it came at a price -- the method may be safer, but it is also less efficient.

Shinya Yamanaka of Kyoto University in Japan said the findings, published in the journal Nature Biotechnology, demonstrate that the stem cell breakthrough may have been exciting, but is nowhere near ready to be used in humans.

Abundant Evidence to Warn People Against GE Crops
November 30, 2007 08:25 AM -

There are thousands of toxic or allergic-type reactions in humans, thousands of sick, sterile, and dead livestock, and damage to virtually every organ and system studied in lab animals. Government safety assessments, including those of Food Standards Australia New Zealand (FSANZ), do not identify many of the dangers, and analysis reveals that industry studies submitted to FSANZ are designed to avoid finding them.

Brain abnormalities mapped in autistic children
November 29, 2007 09:50 AM - Reuters

Autistic children have more gray matter in areas of the brain that control social processing and sight-based learning than children without the developmental disability, a small study said on Wednesday.

Researchers combined two sophisticated imaging techniques to track the motion of water molecules in the brain and pinpoint small changes in gray matter volume in 13 boys with high-functioning autism or Asperger syndrome and 12 healthy adolescents. Their average age was 11.
