Lab Notes: Is space junk destroying the ozone layer?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.

The First InventorsEvidence 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. Authors Sean Ulm, Billy Griffiths and Larissa Behrendt explore these ideas in their book The First Inventors.

Lab Notes: Plants can hear youPlants are more aware of their surroundings then we give them credit for. A growing body of work is showing that plants can change themselves in response to different sounds. Dr Samarth Kulshrestha, a molecular biologist from the University of Canterbury, is one of these researchers, looking at the mechanisms behind plant senses.
