Scientists have long been reading the code of life - the genome -, as a sequence of letters but now researchers have also started exploring its three-dimensional organization.
 
 
 Children born with Down's syndrome have superior genome that compensates for disabilityChildren born with Down's syndrome have superior genome that compensates for disability
 
Down's syndrome - also known as trisomy 21 - is a genetic disorder caused by an additional third chromosome 21. Although this genetic abnormality is found in one out of 700 births, only 20% of foetuses with trisomy 21 reach full term.
