White supremacy or white supremacism is a racist ideology centered upon the belief, and promotion of the belief, that white people are superior in certain characteristics, traits, and attributes to people of other racial backgrounds and that therefore white people should politically, economically and socially rule non-white people.
Neural tube defects occur when the bones of the spine do not correctly form, leaving the spinal cord and its nerves and coverings to protrude out through the skin (or lie just beneath it). The use of folate vitamins during pregnancy has decreased the incidence of neural tube defects.
According to the March of Dimes, neural tube defects happen in about 3,000 pregnancies each year in the United States. About 1,500 babies are born in the U.S. with spina bifida, the most common NTD, according to the National Institute of Child Health and Human Development.
