Language patterns are roller-coaster ride during childhood development

Research from North Carolina State University found that African-American children's language use fluctuates as they adopt and abandon vernacular English patterns. The study, tracking 88 children since 1990, reveals a cyclic pattern in the use of African-American vernacular English.

Fatty liver may herald impending Type 2 diabetes

A recent study published in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism found that individuals with fatty liver were significantly more likely to develop type 2 diabetes than those without. Fatty liver was shown to be an independent risk factor for type 2 diabetes, regardless of insulin resistance levels.

Serotonin plays role in many autism cases, studies confirm

Researchers have found that increasing serotonin levels improves social behavior in mice with autism. A medication called buspirone was used to mimic the effects of serotonin, resulting in improved social interaction behaviors. Further study is planned to investigate the impact of a diet rich in tryptophan on social behavior.
