Here’s what happened when codeine was made prescription only. No, the sky didn’t fall in

In a virtual universe of ‘perfect’ bodies, Instagram’s new policy offers important protection for young users

Adolescence is a time of heightened vulnerability around body image. Instagram’s policy to stop teens viewing posts advertising weight loss ‘solutions’ and cosmetic procedures is socially responsible.

Climate explained: why don’t we have electric aircraft?
