Why does the central nervous system not regenerate after injury?
A major problem for neuroscientists and clinicians is why the central nervous system shows ineffective regeneration after injury. Injured peripheral nerve fibers reform their connections, whereas those in injured spinal cord never re-grow. Insights into the mechanisms for repair and restoration of function after spinal cord injury have been obtained by experiments showing that injured nerve cel...

In the midst of American intervention in Afghanistan and Iraq, and in the aftermath of the presidential election in Iran, support for American involvement in Iran has increased in some circles. In this piece, our desire is to give a conservative, evangelical Christian response to why America should not support any military action against Iran. A position advocated by many of us is “Just War.” I...
متن کاملWhy organizational networks in reality do not show scale-free distributions
This paper discusses chain of command networks that are most likely to exhibit the scale-free (SF) property in organizational networks, explaining why organizational networks do not show SF distributions. We propose an evolving hierarchical tree network model without explicit preferential attachment. The model simulates several kinds of chain of command networks with the span of control ranging...
متن کاملWhy hunter-gatherer populations do not show signs of pleistocene demographic expansions.
The mitochondrial DNA diversity of 62 human population samples was examined for potential signals of population expansions. Stepwise expansion times were estimated by taking into account heterogeneity of mutation rates among sites. Assuming an mtDNA divergence rate of 33% per million years, most populations show signals of Pleistocene expansions at around 70,000 years (70 KY) ago in Africa and ...
