There is little association between tech use and mental health problems in teenagers, according to a new study by the Oxford Internet Institute. Lead author Dr Matti Vuorre is on the show to explain how they analysed data from 430,000 UK and US teenagers and found little or no associations between adolescents’ tech use and mental health problems. But he says the data they were using is limited. Ideally, he wants to use the data that big tech companies hold on our tech use. The findings are published in the journal Clinical Psychological Science.

AI colourisation of historical photos
Gwen Katz, a historical novelist and games designer, explains the problems of colourising historical photos. To test the efficacy of colourisation AI she compared the artificial colourisation of black and white photos with their colour originals and found that the bright colours of the original images were lost when colourised by an algorithm. Marta Mrak from BBC R&D discusses how the problem of loss of colours is being solved, by providing the algorithms with reference images, as well as future challenges for designing neural networks to colourise film.
