A collaboration between more than seventy researchers across the globe has uncovered nine new genes on the X chromosome that, when knocked out, lead to learning disabilities. This international team studied almost all the X chromosome genes in 208 families with learning disabilities--the largest screen of this type ever reported.
Remarkably, the team also found that approximately 1% of X chromosome genes have no apparent effect on an individual's ability to function in the ordinary world 
Changes in gene may stunt lung development in children

Mutations in a gene may cause poor lung development in children, making them more vulnerable to diseases such as chronic obstructive pulmonary disease (COPD) later in life, say researchers at the University of Pittsburgh Graduate School of Public Health and the German Research Center for Environmental Health. Their study, published online in Physiological Genomics, measured expression levels of the gene and its variants in both mouse lungs and children aged nine to eleven.

Abuse Leaves Its Mark on the Brain

Child abuse doesn't just cause emotional problems; it also causes long-lasting changes the brain. A new study shows that in men who were abused as children, a gene involved in stress control is affected even decades later, following a pattern also seen in stressed baby rats.
Rat studies have revealed that maternal neglect alters the workings of the hypothalamic-pituitary-adrenal (HPA) axis, a system that secretes particular hormones in response to stress

A mother's early experiences in life may shape the memories of her children. Providing mice with a stimulating environment can prevent or reverse memory problems, and mother mice can pass these protections on to their pups even if they do not experience the stimulating environments themselves. This involves no known changes to the mice's DNA.
Beach vacations may increase future skin cancer risk in children

Vacationing at the shore led to a five percent increase in nevi (more commonly called "moles") among seven-year-old children, according to a paper published in Cancer Epidemiology, Biomarkers and Prevention, a journal of the American Association for Cancer Research.
Number of nevi is the major risk factor for malignant melanoma, the most dangerous form of skin cancer. Melanoma rates have been rising dramatically over recent decades. More than 62,000 Americans are diagnosed with melanoma each year and more than 8,000 die
Key to Regulation of Puberty Discovered

A team of scientists from the University of Cambridge and the University of Cukurova in Turkey have taken a major step to understanding how the brain controls the onset of puberty.

Puberty is a puzzle for teenagers and researchers alike. Although scientists can explain part of the process that turns children into adults, no one knows exactly what triggers it. Now a team has identified a hormone that helps tell the brain when "it's time!" The find could have broader implications for fertility treatments, contraceptives, and even fighting cancer.
It's no secret that teenagers have raging hormones
Brain reorganizes to make room for math
sea-maid submitted, created time 1 year 3 months (www.sciencenews.org)
It takes years for children to master the ins and outs of arithmetic. New research indicates that this learning process triggers a large-scale reorganization of brain processes involved in understanding written symbols for various quantities.
According to this article, when adults work on math problems, they show activity in a part of the brain known to be associated with linking written symbols to the things they represent, like numerical values, words, and musical notes
Walks through the trees help ADD students concentrate ...scientists aren't sure why
Darkfrog submitted, created time 1 year 4 months (well.blogs.nytimes.com)
For some time, the parents of schoo-aged children with attention deficit disorder and attention deficit hyperactivity disorder have been reporting that allowing children to spend some time outside helps them concentrate, and the effect lasts.
A carefully controlled study out of the University of Illinois at Urbana-Champaign confirms it. Students were separated into groups and taken on twenty-minute walks through either the park, a downtown area or a suburban area. Nothing else was ever changed, not the time of day, not the composition of the groups
Exercise Guidelines: Less Gym, More Fun

New federal guidelines are more of the same. This article recommends at least 2.5 hours per week of moderate exercise or 1.25 hours per week of intense exercise for adults and gives examples. However, the newer note is that people, especially children, will be more likely to stick with the plan if the activity in question si fun.

Surgery may help, but not cure, obese children with sleep disorders

Surgical interventions for many obese children suffering from obstructive sleep apnea may not cure the problem, says new research presented at the 2008 American Academy of Otolaryngology – Head and Neck Surgery Foundation (AAO-HNSF) Annual Meeting & OTO EXPO in Chicago, IL. Obese children are at increased risk for developing obstructive sleep apnea (OSA), a sleep disorder that is associated with a decreased quality of life as well as behavioral, neurocognitive, cardiovascular, metabolic, endocrine, and psychiatric complications
Fat Mum Hastens Path to Childhood Obesity

There is a correlation between children's obesity rates and those of their mothers, finds a new study. Other factors linked to a child's tendency to become obese include too much time spent in front of the TV and rapidly piling on the pounds in early childhood.
High-Fat Diet Found to Fight Seizures in Kids
kavin submitted, created time 1 year 7 months (www.usnews.com)
A diet high in fat—extremely high in fat, that is—has just been shown in a clinical trial to cut seizure frequency in children with severe, drug-resistant epilepsy. It's not a cure, and it's not an easy treatment to stomach, but it works, British researchers reported Friday in the journal Lancet Neurology.
Dr. Atkins himself might have gagged on the therapeutic regimen, which is called the ketogenic diet. It's so fatty that carbohydrates and protein combined aren't permitted to account for more than twenty-five percent of total calories
Lack of time on tummy shown to hinder achievement

The American Physical Therapy Association is urging parents and caregivers to ensure that babies get enough "tummy time" throughout the day while they are awake and supervised, in light of a recent survey of therapists who say they've noticed an increase in motor delays in infants who spend too much time on their backs while awake.
