Welcome to issue 42 of


The exciting science journal for young people aged 14-19 and their educators. Covering scientific research and industrial developments, real life STEM stories, career journeys, STEM expeditions and adventure.

Catalyst Magazine brings STEM subjects to life, showcasing real world topics, issues, and solutions. Written by academics, scientists, engineers, and educators. Published three times a year and accompanied by learning notes filled with activities and ideas to support curricular learning and encourage research and informed debate.

Catalyst delves into the peculiar powers of polarisation within the natural world and the quantum realm before exploring the maths used to survey the Antarctic. We blast off with a look at rocket science and uncover how maths and submarines come together for a sustainability engineer. The secret world of bacteria is uncovered as we explore their dormant status. And finally, we take a journey into the future of medical technology before exploring the past through the eyes of a student scientist looking to use discoveries of the past to shape solutions for the future.
