Back in 2017 Jesse spoke with arachnologist Dr Fiona Cross - or Doctor Spider - about her work investigating how tiny spider brains might understand numbers.
She was nearing the end of a Te Pūtea Rangahau a Marsden (Marsden Fund) grant to study a jumping spider named Portia in Kenya.
An update: Fiona recently secured $926,000 from the Marsden Fund to continue to her research.
She joins Jesse to discuss where this research will take her next.
