Cases of bird flu in farm workers in the US may be going underreported, due to supposed poor surveillance and lack of testing. We hear from Amy Maxmen of KFF Health News who has been reporting on a study in Texas. We hear from Bradley Moore, Professor of Marine Chemical Biology at University of California, San Diego about marine algae using massive enzymes, dubbed PKZILLAs to biosynthesize fish-killing toxins. BBC Science Correspondent Jonathan Amos gives us the latest on the two American astronauts who blasted off on a test mission to the International Space Station on 5 June, expecting to be back home in a matter of days. But the pair are still there, floating high above the Earth two months later - stuck indefinitely - now facing the sudden prospect of missing the summer entirely and even spending Christmas and New Year in space. And sea lion camera crews are helping researchers explore previously unmapped ocean habitats in southern Australia. Nathan Angelakis of the University of Adelaide tells us about working with the animal camera operators and what we can learn from viewing their movements.

I'm Rory Stewart, and I want to talk about ignorance.
I will die without having read everything that was written in classical Latin, because ignorance isn't simply the opposite of knowledge, it's part of what it means to be human.
Just about every game I can think of involves ignorance.
There's no adventure without ignorance.
There's no narrative.
The long history of ignorance from Confucius to QAnon.
With me, Rory Stewart.
Listen on BBC Sounds welcome to science in action from the BBC World Service.
With me, Roland Pease.
And this week we've the olympian algae with proteins that outrank anything seen before.
Also, sea lions turned camera crew.
A sea lion might be really quickly pursuing a fish that's really fast and moving away from it.
You have this animal just darting in and around rocks and reefs, and there are some moments that are very fast paced and you're trying to keep up and id everything that's happening and lost in space.
The NASA astronauts, whose eight day visit to the International Space station could turn into an eight month one.
First, we've been banging on, on the program about the continued spread of the highly pathogenic h five n one type of bird flu, particularly through milk herds in the US.
The first edition on that front was at the beginning of April.
And the concern I keep hearing from the experts since then is that not enough surveillance is being done to understand the virus's continued spread past.
Pandemics have started when the adaptable virus moved from flocks or farm animals into those in contact with them, presumably the farm workers.
At the very least.
What we have now is a chance to scientifically study how an infection might behave before a human outbreak.
