Study design: groups, ages and epigenetic clocks

A new review of screen use and sleep in young people finds no link between the amount of use and sleep quality or duration.

When a young child comes to hospital with a broken bone or a bad sprain, how should their pain be managed?

And could a multivitamin slow your rate of ageing? Spoiler - no, not really.

But there's a little more to it ... and it involves epigenetic clocks. For more on that story, read this piece from our colleagues on the ABC Science digital team.
