Talking Points

Recent interactions between the hosts and their guests.

Honeybees, climate change and pollination
Q: Alison in Wodonga asks why some deciduous plants change leaf color in cold weather.
Leaves lose chlorophyll in winter; carotenoids reveal orange/red colors, and some plants may have hairs or other features that reduce water loss and protect tissues in cold, dry conditions.
Honeybees, climate change and pollination
Q: Jade in Brisbane asks how to pollinate fruit trees when local bees have disappeared.
Encourage biodiversity by planting native plants to attract alternative pollinators and create a garden ecosystem that supports various pollinator species, which can help with pollination even when European honeybees are scarce.
Radio stars, spiral galaxies and threadworms
Q: What was the most recent astronomical discovery that blew scientists' minds?
Laura describes long period radio transients and other slow, repeating radio bursts as a surprising recent development, illustrating how new data can overturn expectations in astronomy.
Black tea, pins & needles and toilet doors
Q: Can you stop yourself from sneezing?
The hosts explain that you can suppress a sneeze temporarily through controlled breathing or swallowing, but generally you don't want to suppress it because sneezing is a normal reflex; suppressing it can push irritants into the sinuses.
The third eye, scented candles and norovirus
Q: Rosanne asks if there will ever be a finite limit to musical notes in an octave given tempo and rhythm changes.
Dr Karl explains that with 12 semitones per octave, tempering and extending scales can create exponentially many unique note sequences, so while there are practical limits, mathematically there are vast possibilities depending on how you combine notes, rhythms, and dynamics.
