|An earthy non-prescription anti-depressant|
Grist - 4/8/2009.By Kit Stolz – Medical researchers in the United Kingdom have found evidence that “friendly” bacteria found in soil may activate the immune system, produce the brain compound serotonin, and help ward off depression. According to a study published last week in Neuroscience, researchers from Bristol University and University College London found that mice treated with the soil agent Mycobacterium vaccae behaved much like mice treated with anti-depressants.
|Pesticides blamed for some childhood brain cancers|
Organic Consumers - 4/8/2009.By Heather Hamlin, Environmental Health News – Little is known conclusively about what causes brain cancer in children, but research studies are consistently finding links to prebirth pesticide exposure. A new study finds that children who live in homes where their parents use pesticides are twice as likely to develop brain cancer versus those that live in residences in which no pesticides are used. Herbicide use appeared to cause a particularly elevated risk for a certain type of cancer.
