A brain chemical recently found to boost trust appears to work by reducing activity and weakening connections in fear-processing circuitry, a brain imaging study has discovered. Scans of the hormone oxytocin's effect on human brain function reveal that it quells the brain's fear hub, the amygdala, and its brainstem relay stations in response to fearful stimuli. The work suggests new approaches to treating disorders involving social fear, such as social phobia and autism. Umbilical Cord Clamping Should Be Delayed,Says Expert

Researchers at Johns Hopkins have shown that transplanting human stem cells into spinal cords of rats bred to duplicate Lou Gehrig's disease delays the start of nerve cell damage typical of the disease and slightly prolongs life. The grafted stem cells develop into nerve cells that make substantial connections with existing nerves and do not themselves succumb to Lou Gehrig's, also known as amyotrophic lateral sclerosis (ALS). The study is published in this week's issue of Transplantation. PCs Get Set to Scream in 2007

Groundbreaking new discoveries have opened the door for a new and better understanding of Alzheimer's disease, as one of the most important future public health challenges.

Neuronal and synaptic losses in AD are correlated with dementia and occur in specific brain areas involved in memory processing. Long-standing evidence shows that progressive cerebral deposition of A plays a seminal role in the pathogenesis of AD. Moving Wildlife Detrimental To Oral Rabies Vaccination Project
