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.

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.

Right now, a high-stakes mission is underway to save NASA's Swift telescope before it falls back to Earth.

There's just one problem… the rescue satellite has run into some issues. So who rescues the rescuer?

Jonathan Webb and Dr Sara Webb launch into this issue to see what scientists are doing to get this satellite back on track, and whether it can save Swift in time.

Editor's note: the day after this episode was published, Australian time, NASA announced that its plan to boost the Swift Observatory was being abandoned because of ongoing issues controlling the pointing of the LINK spacecraft. It will still test out "rendesvous and proximity operations" which might provide useful results for similar missions in the future, but will not attempt to grab and lift the telescope as planned.

The last days of winter are here and already you may be seeing flowers blooming around you. Why is that? How do flowers know when to bloom, and is it always around springtime?

Jonathan Webb digs into these questions with Dr Greg Moore to try and uncover the mechanisms behind flowering plants.
