Scientists flash videos of brain development in fragile X
Scientists have for the first time captured a dynamic picture of brain defects in young mouse models of fragile X syndrome. The findings appeared in June in the Journal of Neuroscience.
From funding decisions to scientific fraud, a wide range of societal factors shape autism research.

The mouse brain has more than 1,300 regions for which the copy from one parent is expressed more often than the one from the other parent, according to two studies published today in Science. These so-called imprinted genes have been proposed to cause some cases of autism, but the researchers say their findings do not support that theory.
A clever new method records brain activity during live, back-and-forth social interactions and could help scientists study joint attention — the act of looking at an object the same time someone else does.
The U.S. government last week announced a $1 million multi-agency initiative that will evaluate how many new ideas, jobs and medical advances have been generated by its investment into scientific research.
The challenge of finding jobs for adults with autism is the focus of a special issue of the Journal of Vocational Rehabilitation. With the right training and tools, the articles suggest, it’s possible for many people with the disorder to be gainfully employed.
Chromosomal microarray analysis, which screens the entire genome for tiny blips in the sequence, should be the first genetic test performed when diagnosing autism, says a consortium of clinical geneticists. The recommendation comes on the heels of a study that found the test is three times more effective at spotting autism variants than are standard clinical methods.
Some children with autism prefer to look at geometric patterns rather than at ‘social’ images of other children — and this tendency is obvious as early as 14 months of age, according to a poster presented today at IMFAR 2010 in Philadelphia.
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.
Some brain areas involved in speech are larger and some smaller in children with autism compared with healthy controls, according to a series of imaging studies conducted by a Boston research group.
A whopping 95 percent of children with autism have at least three other psychiatric disorders, and 74 percent have five or more, according to a study in the Journal of Autism and Developmental Disorders.
