Matt Baker returns for a chat about some of the latest science news.
This week: why a single shot of gene therapy may replace surgical sterilisation for cats, how accidentally collected airborne DNA offer a biodiversity snapshot, and a new brain–spine interface that has digitally bypassed a spinal cord injury, allowing a tetraplegic to walk.
Dr Baker is Scientia Associate Professor in the School of Biotechnology and Biomolecular Science at the University of New South Wales in Sydney.
