A new study from Cambridge University has for the first time found that autism diagnoses are more common in an IT-rich region. The Medical Research Council (MRC) funded study, published today in the Journal of Autism and Developmental Disorders, has important implications for service provision in different regions and for the ‘hyper-systemizing’ theory of autism.

A team of researchers have discovered that, on average, thirty mutations are transmitted from each parent to their child, revising previous estimations and revolutionizing the timescale we use to calculate the number of generations separating us from other species. “Your genome, or genetic code, is made up of six billion pieces of information, called nucleotides,” […]
For the first time, a research group at Lund University in Sweden has succeeded in creating specific types of nerve cells from human skin. By reprogramming connective tissue cells, called fibroblasts, directly into nerve cells, a new field has been opened up with the potential to take research on cell transplants to the next level. […]
A clinically extensive and mathematically powerful study of 1000 families with one autistic child and one unaffected sibling has validated a controversial theory of autism’s complex genetic causation. The study for the first time estimates the minimum number of locations in the human genome – 250 to 300 – where gene copy number variation (CNV) […]
For decades, autism researchers have faced a baffling riddle: how to unravel a disorder that leaves no known physical trace as it develops in the brain. Now a UCLA study is the first to reveal how the disorder makes its mark at the molecular level, resulting in an autistic brain that differs dramatically in structure […]
New research involving the University of York explores the interplay between genes and environment when determining whether a mother is at high or low risk for post-natal depression. As part of the continuing Fragile Families and Child Wellbeing Study, launched in 1997, researchers, including Professor John Hobcraft, of York’s Department of Social Policy and Social […]
Children whose mothers or grandmothers smoked during pregnancy are at increased risk of asthma in childhood, but the underlying causes of this are not well understood. Now a new study indicates changes in a process called DNA methylation that occurs before birth may be a root cause. The study will be presented at the ATS […]
Researchers at Washington University School of Medicine in St. Louis and King’s College London have independently identified DNA on chromosome 3 that appears to be related to depression. Jim Dryden explains these results in an audio interview with the researchers; check the end of this report for a link to this interview.
