Calls in Canada for trials of a contentious treatment for multiple sclerosis illustrate how social media can affect research priorities, say Roger Chafe and his colleagues.

With the death of Veronica Rodrigues on 10 November, India has lost a leading figure in the resurgence of research and teaching in the biological sciences in the subcontinent. Her scientific influence was widely felt, but she was also intimately connected with fostering and advancing research in molecular biology and developmental genetics at the Tata Institute of Fundamental Research (TIFR) in Mumbai, and more recently in the inception of the landmark center of excellence at the National Centre for Biological Sciences (NCBS) in Bangalore.

Luc Montagnier is applying unorthodox ideas to the treatment of autism. With support from the Autism Research Institute (ARI), based in San Diego, California, the Nobel laureate is about to launch a small clinical trial of prolonged antibiotic treatment in children with autism disorders.

Childhood diet is important for brain development. Furthermore, the quality of breakfast is thought to affect the cognitive functioning of well-nourished children. To analyze the relationship among breakfast staple type, gray matter volume, and intelligence quotient (IQ) in 290 healthy children, we used magnetic resonance images and applied voxel-based morphometry.

The purpose of this study is to explore whether sustained exposure to vehicular air pollution affects the behavior and activities of children. The prevalence of attention-deficit hyperactivity disorder (ADHD) was assessed in two childhood populations.

Yoga and exercise have beneficial effects on mood and anxiety. g-Aminobutyric acid (GABA)-ergic activity is reduced in mood and anxiety disorders. The practice of yoga postures is associated with increased brain GABA levels. This study addresses the question of whether changes in mood, anxiety, and GABA levels are specific to yoga or related to physical activity.

Studies using reconstructed exposure histories have suggested an association between heavy metal exposures, including lead, and Parkinson's disease (PD), and a study that used bone lead as a biomarker of cumulative lead exposure also reported a nonsignificant association with PD. Weisskopf et al. estimated the association between bone lead and PD among 330 PD patients and 318 controls.

This new study confirms that children in Faridkot area have for long been exposed to a large number of heavy metals, including lead, barium, cadmium, manganese and uranium. It has the study has been conducted by Baba Farid Center for Special Children. <br>

Long-term neurotoxicity risks resulting from prenatal exposures to pesticides are uncertain, but a previous study of Ecuadorian schoolchildren suggested that blood pressure and visuospatial processing may be vulnerable to these exposures. Harari et al. conducted a cross-sectional study of cardiovascular and neurobehavioral functions among 84 Ecuadorian children 6

Water supplies in many regions of the world are contaminated with arsenic, which is known to cause several diseases including cancer and skin lesions. Less is known about effects of arsenic on the nervous system, especially following developmental exposure. Wang et al.
