Williams syndrome precludes racial bias, study finds

by  /  20 May 2010

Children with Williams syndrome — a rare genetic disorder that leads to mental retardation and overt friendliness — hold stereotypes based on gender, but not race, according to a report published in Current Biology. Because those with Williams syndrome don’t have social fear, the study suggests racial stereotypes are based partly on fear.

Study implicates cell-adhesion proteins in autism

by  /  18 May 2010

Variations in two genes needed to form connections between brain cells may be associated with autism spectrum disorder, according to a study published 25 March in Molecular Autism. Some variants in the genes seem to increase susceptibility to autism, whereas others protect children from developing the disorder.

Mouse models reveal workings of neuroligin-1

by  /  4 May 2010

Researchers are tinkering with mouse models to investigate the function of a protein that helps wire neurons together and that has repeatedly been linked to autism. Three such reports of the protein, neuroligin-1, have appeared this year.
