From today's Globe and Mail:
New research suggests our capacity to remember things is lower than previously thought.
Our working memories may max out at three or four items, according to a study published this month in the journal Proceedings of the National Academy of Sciences.
Earlier research had pegged that number at about seven. But the study by University of Missouri researchers suggests the true number is lower when people are not allowed to use memory aids, such as grouping items together or repeating them over and over.

Chromosome abnormality linked to autism, study finds
Researchers have identified a chromosomal abnormality that seems to increase a person's chances of developing autism.
A group of U.S. researchers, associated with a group of Boston-based hospitals known as the Autism Consortium, conducted complete genome scans of 1,400 samples of DNA from families of autistic children.
They found that in one per cent of people with autism, or similar disorders, a portion of chromosome 16 is either absent or duplicated. This is not inherited from the parents.

Gifted children 'caused distress by TV news'
A leading Australian expert on gifted children has warned parents about the effects of watching television news.
University Professor Mirica Gross says highly-gifted children are often more sensitive and deeply feel the sadness of others at a very young age.

Researcher sees link between vitamin D and autism
Globe and Mail
The growing prevalence of autism is one of the biggest scientific whodunits in the medical world, with few clues for its rising incidence.
But a U.S. researcher is advancing a controversial hypothesis: that autism is related to vitamin D deficiency during fetal development and early childhood.
Dr. John Cannell, a psychiatrist and prominent vitamin D advocate, says flagging levels of the vitamin in pregnant women and young children could be the elusive factor explaining the rising rate of autism.
The evidence for such a link is circumstantial, and autism experts describe the hypothesis as speculative. But Dr. Cannell, founder of the Vitamin D Council, a non-profit advocacy group, says autism rates have skyrocketed in lockstep with medical advice given to the public since the late 1980s to avoid all exposure to bright sunshine.

Study: Learning disorders might be genetic
Here is the link to the journal where you can read the article discussed in this article below: http://www.blackwell-synergy.com/doi/full/10.1111/j.1751-228X.2007.00002.x
LONDON, March 14 (UPI) -- A British researcher suggests a wide variety of learning disabilities might be caused by "generalist" genes.
"Old studies tend to focus on finding the genes responsible for single disorders," said review author Robert Plomin, "but with the new analysis techniques available, new studies are providing evidence that genes can be responsible for a wide range of learning disorders."
