Also, cerebral palsy is not a single problem, but a complex disease in which virtually all brain cell types could need repair.

"Although these deadly viruses were isolated from dead migrating birds, we don't know if the birds are actually spreading H5N1," ...Animal research suggests plant estrogens in soy do not increase breast cancer risk
