My science writing has always been motivated by big, philosophical questions. What are the laws of nature and where do they come from? Are humans inherently kind and cooperative or selfish and competitive? What about other animals? Will our species relearn to live in balance with the natural world? How do we get there?
Why do some child soldiers heal and not others? What one scholar found.
When a brutal war births a generation of child soldiers, why do some succumb to despair while others recover and thrive? A pivotal study suggests connection and community may be key to healing.
