Across the long history of medicine, sleep has been observed as both a mirror and a maker of mental suffering — its disruption a signal, its restoration a hope. Now, researchers at Maynooth University are leading a twelve-institution international programme called DataGenChrono to move beyond that observation and into the biological architecture beneath it, tracing the genetic and neurological pathways that bind sleep to depression, anxiety, bipolar disorder, and schizophrenia. Drawing on genomics, artificial intelligence, and vast health datasets spanning Europe and Canada, the effort seeks n
