In the past, increasing the speeds of electronics required designing smaller components, but further reductions in size are being hampered by increasing resistance. To get around this, researchers have demonstrated a ‘metadevice’, which prevents resistance building up by concentrating the flow of signals into specific regions of the device. The hope is that this meta-method could be used to create even smaller electrical components in the future.

In the last ten years, levels of social media use and reported levels of mental health issues among adolescents have both increased. There is much concern that these trends are linked, but hard evidence has been hard to come by. So how can scientists get a better understanding of what’s going on? In a Comment article for Nature, researchers argue that, rather than lumping ‘young people’ into one homogeneous group, future studies should consider where they are in terms of their development, as this could influence the potential impacts of social media use.
