Genes not solely to blame for different types of autism

Scientists have revealed a new cause of autism spectrum disorders that has nothing to do with your DNA. These disorders share similar modifications in the brain that are independent of genetic activity.

The
study, conducted at the Genome Institute of Singapore, showed that nearly 70% of individuals with both rare and common types of autism spectrum disorder display a similar pattern of histone acetylation.

A powerful study in embryology by a team from European Molecular Biology Labs (EMBL), Heidelberg, Germany and Institut Curie, Paris reveals what drives cells in becoming the fetus rather than the placenta very early in mouse embryo development.

Soon after the sperm and egg meet forming an embryo, it divides into a mass of cells. According to the lead author at Institut Curie, Dr. Jean-Leon Maître, "In the very first days of our development, cells make their very first decision of either...
