    This should be a good program but with.altered narrative, very female view. I think woman’s hour around science with hint of anti men.

Talking Points

Recent interactions between the hosts and their guests.

Taking a shortcut
Q: Is it true that only Japanese people can digest seaweed?
Most gut enzymes cannot digest seaweed's dietary fibres, but a small study found that some gut bacteria in Japanese participants could break down a particular carbohydrate in nori. Seaweed can still provide digestible protein, omega-3 fatty acids, minerals and vitamins.
Taking a shortcut
Q: What is quantum teleportation?
It transfers information about a quantum state to a particle of the same type elsewhere. No physical object travels between the locations; entanglement enables the transfer.
Rogue Agents
Q: John asks why hair grows in places where it shouldn't and stops on the top of the head.
Desmond Tobin explains that hormones like androgens drive hair growth patterns differently across body sites; scalp follicles shrink while eyebrow and ear follicles can become more active with age, explaining the characteristic baldness and growth in other areas.
A distorted view
Q: why are all the continents pointing downwards?
The orientation is a historical artifact of how continents split from Gondwana about 200 million years ago; there is no physical force pushing them that way today, it's a relic of tectonic history.
The phizz-whizzing science of Roald Dahl
Q: What is the universe expanding into?
It's not expanding into anything; space-time itself is expanding and creating more space over time.
