Heman Bekele, a 15-year-old from Virginia, US, has been honoured by Time magazine for his pioneering work and research into skin cancer treatment.
Heman was four years old when he started conducting his own science experiments at home, creating concoctions with whatever he could find. At six, he was given a chemistry set for Christmas, helping Bekele to the realisation that he wanted to help the world in some way using science.
He grew up in Ethiopia, witnessing first-hand the damaging effects of the sun, particularly on labourers, who often work in the blistering sun without skin protection. Bekele was shocked to realise that the cost of skin cancer treatment for those without insurance could be up to $42,000 (£32,000). It became his mission to come up with a more affordable treatment.
