The only three U.N. nations not to ratify the treaty are Somalia, South Sudan and the United States. To mark the twenty-fifth anniversary of the CRC, the UCLA World Policy Analysis...

At the Max Planck Institute for Human and Brain Cognitive Brain Sciences in Leipzig, Germany, scientists were keen on finding out the connection between self-generated thoughts (SGT) and levels of psychological stress indicators. SGT are simply the thoughts that are unrelated to any task being performed. Among others, these thoughts include daydreaming and mind wandering. Some previously conducted studies indicate that SGT do not only...

Cell interconnections in propagation of misfolded proteins in neurodegenerative diseases act like international air routes in the spread of infectious disease epidemics. That is the main finding of a new study in the journal PLOS Computational Biology. The study comes from a research team based in the Montreal Neurological Institute in Canada.

Older people tend to avoid noisy places. Noise can be very distracting to the brain of an elderly person which is less able to filter out background noise and other distractions to maintain focus on a goal. Distractibility is a hallmark of the aging mind, that can affect daily activities, but a new study led by researchers at the University of California, shows that the brains of elderly humans and rats can be trained to better ignore...

Traumatic brain injury to the cerebral cortex activates these glial cells, but does not stimulate production of new neurons. This observation implies that, while supporting cells can help promote neuronal survival, once these neurons are lost they cannot be replenished. However, previous work conducted in cell culture has shown that overexpression of certain transcription factors in some types of supporting cells, including astroglia and...
