Episode 4 of Interronauts and we’ve got a cracking line-up of topics. From non-CSIRO news, we’ll be talking about tardigrades and how in tardigrades’ name they can survive in space, the origins of the human nose – in all their nosey glory, why some droplets splash more than others, and foxes climbing koalas’ trees. From CSIRO news, we talk about using trackers as digital shepherds. And we speak with Ken McColl, the CSIRO researcher behind the ambitious plan to combat Australia’s carp pest problem with a strain of herpes.

Sheep with Fitbits

“Erase that image of headband wearing, treadmill running sheep from your mind (sorry). But in the same way that wearable devices such as Fitbits log your activity and health, activity trackers could soon be a vital tool for Australian farmers to monitor the health and behaviour of their sheep,” from our blog.
