Genes affecting brains and brawn?

Genes located in "copy number variants" (CNVs) — parts of chromosomes that are missing in some individuals and duplicated in others — that are associated with neurodevelopmental disorders affect more than just brain development, according to new research..

Apparent new rise in autism may not reflect true prevalence

New statistics on autism prevalence in the United States suggest a dramatic rise in the number of children with the condition. But it is unlikely that these numbers reflect a true rise in prevalence, experts say.

Researchers Create Mini Livers To Test Disease Progression

Scientists have bioengineered miniature human livers – possibly for the first time. The livers were created by University of Pittsburgh researchers in an effort to move away from less reliable experiments on mouse livers.
