Dr Shane is joined in the studio by Dr Laura and Dr Ray, who share news on beef-flavoured rice grown in the lab and shocking findings by European researchers that microplastics penetrate so deeply into lake sediment that they enter layers laid down before plastics were even invented. Dr Shane interviews three guests: Dr Mehrnaz Shoushtarian from the Bionics Institute shares her research leveraging light-based brain imaging and machine learning to detect tinnitus-related brain changes. This could help to measure effects of new treatments for tinnitus and better identify different types of tinnitus to tailor the treatment. Dr Jayden Newstead from University of Melbourne's School of Physics shares his research, which aims to develop new techniques to detect less frequently occurring types of dark matter. A/Prof Nadia Zatsepin is an ARC Future Fellow from La Trobe University, and her research uses X-rays to image molecules in real time, creating "molecular movies" to better understand the mechanics of certain proteins.
