As the season for flu comes round again, Simon hears of the lessons learnt from last year's Swine Flu epidemic and how the internet is both hindering and helping the public understanding of its spread. Reasonable people with unreasonable responses: why is it that message boards and forums often contain the most hostile of comments? Simon hears from the worst type of these offenders- a troll- and tries to understand the psychology of their behaviour. And we discover how endangered animals' footprints are being tracked digitally to give scientists the ability to follow the movements of such species as the Bengal Tiger, Black Rhino....and the domestic dormouse. Produced by Lucy Lloyd.
