Scientists at University College London and the Italian Institute of Technology have created a temporary tattoo with light-emitting technology used in TV and smartphone screens, paving the way for a new type of smart tattoo with a range of potential uses.

More than a third of teenagers in the UK are starting adult life overweight or obese, according to research.
Scientists at University College London said those from poorest families are at the greatest risk, with rates of obesity twice as high among this group compared to those from the richest households.
According to the report published by the Centre for Longitudinal Studies (CLS) at the UCL Social Research Institute, one in five (21%) young people were obese at age 17, and a further one in seven (14%) were overweight.
