The Science Show

The Science Show gives Australians unique insights into the latest scientific research and debate.

Most people know the feeling of ticklishness, whether it's the tickle attacks that bring about uncontrollable laughter or the feather-like touch from something brushing against your skin.
But why do we feel ticklish? Can we stop it? And why did we — and all our ape cousins — evolve this sensation?
Jonathan Webb speaks to Dr Anina Rich to explore the science of this everyday experience.

Dust storms on Mars make the biggest on Earth seem like a gentle breeze. Chelsea Huang describes the Martian conditions which produce humungous dust storms that cover the entire planet.

These little spiders that live in the dark corner of your garage have a pretty crazy sex life. Researchers have known for a while that male redback spiders get eaten during sex — but not only that, they somersault themselves right onto the fangs of the female.
Considering the ultimate aim of this process is to create more spiders , this seems pretty counterintuitive. So it begs the question: why do they do it?
Jonathan Webb and Ellen Phiddian get caught up in the science of this act, discussing what researchers have uncovered in the genes of the redback spider and its relatives.
