We don't know a lot about deep-sea eels, so when 2.8 million of them are found in the same place every year, scientists (and science reporters) get excited. Why are they there? Where are they coming from, and why should we care about these creatures from the depths? Jonathan Webb dives into this world of eels off the coast of Tasmania with environment reporter Peter de Kruijff.

Across south-eastern Australia, bogong moths seem to be everywhere. A few years ago, it was a different picture: scientists witnessed a population crash, and habitat threats put the species on the IUCN Red List. Are we seeing a bogong bounce-back? Jonathan Webb speaks to Dr Kate Umbers about these incredible critters, the many unsolved mysteries of their lives — and what their future could look like.

Over the past few years, our environment seems to have experienced multiple extreme events in quick succession. With a summer fuelled by what may be the strongest and wettest El Niño ever, can our wildlife withstand more extremes? Jonathan Webb speaks with Professor Euan Ritchie about what we're currently seeing with flying foxes, what could happen to other species over the summer, and what we can do to help our native creatures.

And palm oil producers in South-East Asia have changed their ways, considering the environment more than they did. Brendan May is turning his attention now to nickel mines in tropical countries.

In March 2018, a South African astronomer looking into the distant universe "discovered" a bright red spot in the sky that hadn't been there previously; it felt like an exciting potential discovery. A message was sent to other astronomers, asking them to look at this new dot and study it further. After forty minutes and a few more calculations, he realised this "star" was much closer to home and nothing new at all: it was the planet Mars. According to Dr Kat Ross, making this kind of mistake is something of a rite of passage for astronomers.

Your phone battery doesn't like being fully charged or discharged. This is why it's sometimes advised that to extend its life, you shouldn't charge your phone beyond 80 per cent, or let it drop below 20 per cent. But what's actually happening inside a lithium-ion battery to cause this effect, and what does it mean for battery engineering — and the life of the battery in your phone, or your electric car?

Millions, perhaps billions of sharks teeth lie on the ocean floor. Valuable mineral deposits collect on their fossilised remains. Now they are viewed as a resource and if exploited devastation will come to an little known ecosystem.

Deep in an old gold mine in South Dakota, scientists witnessed a flash of energy in a giant pool of xenon. Some in the astronomical community are pretty excited, saying this is our best hint yet at what dark matter is. How do we know, why does it matter — and what happens next?

It's been three months since the first case of bird flu was found on the Australian continent. Many cases have been found in birds since then, along with other mammals. So where has it spread?

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?

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.

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.…

Old satellites and bits of space junk regularly fall back to Earth, burning up as they pass through the atmosphere. All this burning metal causes a chain reaction and ultimately destroys ozone molecules, which keep us safe from most of the Sun's harmful UVB rays. Could a new era of satellite "megaconstellations", like the one run by SpaceX's internet company Starlink, undo humanity's hard work repairing the ozone layer? ‌Jonathan Webb launches into this issue with Dr Alice Gorman (AKA Dr Space Junk), taking stock of just how many satellites are burning up and what can be done to solve the problem.

Evidence is mounting that Indigenous people were in Australia early than the 65,000 date most now know. And there are suggestions the continent supported a population of at least 2 million people.
