How could spider sex unlock secrets to engineering?

Not everyone is the biggest fan of spiders...we know that. They might not be the first thing that springs to mind when it comes to romance, either! But, you've got to admit, when it comes to engineering, they're pretty incredible. Capable of making up to seven types of silk, and able to sense vibrations through thousands of 'ears' on their legs, there's a lot we can learn from spiders when it comes to new materials and sensor technologies. So, on this year's Valentine's episode of the Big Questions Podcast, we're asking arachnologist Dr Beth Mortimer how spider mating rituals could help us become better engineers.
