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.You can binge more episodes of the Lab Notes podcast with science editor and presenter Jonathan Webb on the ABC Listen app (Australia).

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.You can binge more episodes of the Lab Notes podcast with science editor and presenter Jonathan Webb on the ABC Listen app (Australia).

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.You can binge more episodes of the Lab Notes podcast with science editor and presenter Jonathan Webb on the ABC Listen app (Australia).

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.Get in touch with us: [email protected]:Dr Sara Webb, Swinburne University of TechnologyThis episode of Lab Notes was produced on the lands of the Gadigal, Ngunnawal and Ngambri people.

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.You can binge more episodes of the Lab Notes podcast with science editor and presenter Jonathan Webb on the ABC Listen app (Australia).

It's census time, which means lots of us are about to submit personal information via the Internet.Whether it's the ABS or your favourite online shop — how safe is our data in an era when AI models have shown they can hack companies without even being asked to?Jonathan Webb opens a back door to this new normal of cybersecurity with Professor Toby Murray.You can binge more episodes of the Lab Notes podcast with science editor and presenter Jonathan Webb on the ABC Listen app (Australia).

The longest survey of our southern skies — The Legacy Survey of Space and Time (LSST) — has just begun from the Vera Rubin Observatory in the Chilean Atacama Desert.Over the next 10 years, the largest digital camera on Earth will look at the same patches of sky time and again, aiming to record exploding stars, new asteroids, and maybe find what's behind dark energy.Jonathan Webb gets sucked into grand cosmic questions with Dr Anais Möller, as they discuss how astronomers are getting a head start on their research from the survey.You can binge more episodes of the Lab Notes podcast with science editor and presenter Jonathan Webb on the ABC Listen app (Australia).

This year has been one of the worst starts to the snow season since records began. And it's a trend that researchers say will only continue in the years to come. But what's causing this change? What's the outlook for the rest of this ski season, and should we all just be booking a holiday to Japan? Jonathan Webb goes off-piste with climate reporter Romy Stephens about what this all means.
