A rising star in the male-dominated world of science, Macinley Butson achieved international success in 2017 when she received the First Award in the category of medical science at the prestigious INTEL International Science and Engineering Fair. Each year, more than seven million high school students develop original research projects for the world’s largest international science competition. Macinley’s idea, ‘Smart Armour’, is a shield that can be used by breast cancer patients to protect their non-treated breast while undergoing radiotherapy treatment. A prolific inventor, 17-year-old Macinley has also taken home science awards for other exceptional ideas, such as a system that simultaneously collects solar power and filters water, a spoon that accurately measures and delivers oral medicine to children, and a device that deters garden snails without the use of poison. While empowering young people to embrace science, Macinley also demonstrates the power of giving back to the community as a national youth ambassador for environmental organisation, Green Cross Australia.
