Otago University geneticist Associate Professor Julia Horsfield points out that, without genome sequencing or the discovery of the structure of DNA and the principles of sequencing DNA, her work investigating how chromosome structure and development affects the function of genes involved in cancer would not be possible. Watch this video to find out why Dr Julia Horsfield, sees herself as part of a wave of advancing scientific knowledge and why she believes collaboration is so important. It might be that they continue and grow the work of the scientists who have mentored and supervised them or that they build on prior discoveries – both recent and historical. Scientists today build on the knowledge and discoveries made by others. For example, where would computer technology be today without the development of the silicon chip in 1959 and then advanced ceramic versions of it? How long would it have taken humans to learn more about disease if Antonie van Leeuwenhoek hadn’t scraped some gunk off his teeth to examine under a microscope? Microscopy developments have accelerated learning around microorganisms, cells and inorganic materials, enabling great advances in fields from human health and medicine to materials science and space travel. Tying in stories of science in history and scientific breakthroughs can offer engaging opportunities for further exploration and learning.
