Talking Points

Recent interactions between the hosts and their guests.

Night sweats, time travel and dog poo
Q: Sometimes our dog eats its own poo. I don't know why.
Karl discusses possible nutritional and evolutionary explanations. Canine rehabilitation assistant Andrea adds that diet, eating too quickly and gut imbalance may contribute, and suggests reviewing the dog's food and gut health.
Night sweats, time travel and dog poo
Q: I was reading an article the other day that scientists at Northwest University managed to trap and freeze an antimatter particle. Are there any actual practical applications for this kind of research that we might start seeing results from in either the short term or the longer term?
Karl says antimatter is already used in PET scans to help diagnose medical conditions. He describes concentrated energy as a possible future application, but says antimatter is difficult to store and its properties still need to be better understood.
Bruising, cockatoo schedules and roasted potatoes
Q: I've had surgery on both my feet to remove bunions, and I was wondering, is it inevitable that they're going to come back?
Dr Karl says bunions have genetic and lifestyle influences, and recommends roomy footwear, foot-strengthening exercises, attention to walking mechanics and regular follow-ups with qualified health professionals.
Bruising, cockatoo schedules and roasted potatoes
Q: Why does the sauna get hotter and feel hotter when you put water on the coals?
Dr Karl explains that water increases humidity, making sweat evaporate less effectively, and that hot water droplets can land on the skin and transfer heat.
Coral bleaching, bioluminescence and intelligent fish
Q: I was just wondering what we know about how intelligent fish are.
Ceccarelli describes fish memory, navigation, recognition of other species, tool use, and mirror-test results in cleaner wrasses as examples of fish abilities.
