Between bone-lines
\nand water\u2019s map,
\nwhat lingers moves unseen \u2013
\na script of salt,
\nunspooled beneath the skin.
\nThe child does not know
\nthe weight they carry,
\nhow old hands pressed
\nbefore they curled to form
\nthemselves.
\nThrough blood-thread
\nand quiet etching,
\na mark remains \u2013
\nnot of wounds seen
\nbut of what was given
\nwithout touch.
\nIn the marrow\u2019s hush,
\na memory takes root
\nnot as story
\nbut as something the body
\nhas always known.<\/p>\n

This poem is inspired by recent research<\/a>, which found war-related trauma changes DNA in Syrian refugee families, affecting children and grandchildren.<\/p>\n

Violence does not just affect those who experience it directly – it can have lasting effects across generations. Trauma during pregnancy may alter how genes function through biological changes known as epigenetic modifications, potentially shaping long-term health. While past research has shown that trauma impacts individuals, less is known about how these effects are passed down. Understanding this process is crucial for recognising the lasting consequences of conflict and displacement, particularly for refugee communities.<\/p>\n

This study examined DNA patterns in three generations of Syrian refugees to explore how war-related violence influences gene expression. Analysing biological samples from 131 participants, researchers found clear genetic markers linked to both inherited and direct exposure to violence. Children exposed to trauma before birth showed signs of accelerated ageing, highlighting pregnancy as a critical period of vulnerability. This research offers the first direct evidence of a biological signature of intergenerational trauma, shedding light on how conflict affects families long after it ends.<\/p>\n
