AudioMoth is a low-cost, full-spectrum acoustic logger, based on the Gecko processor range from Silicon Labs. Just like its namesake the moth, AudioMoth can listen at audible frequencies, well into ultrasonic frequencies. It is capable of recording uncompressed audio to microSD card at rates from 8,000 to 384,000 samples per second and can be converted into a full-spectrum USB microphone.

Looks a bit tricky to actually buy at the moment, but interesting device.

Listened Feeding the People in Wartime Britain From National Kitchens to British Restaurants by Jeremy Cherfas from eatthispodcast.com
At the same time, during both World War One and World War Two, there were concerted efforts to feed people. It started with centrally cooked meals that people took home to eat, but soon blossomed into a far-reaching network of government-run restaurants.

Another really interesting episode from Jeremy Cherfas. I’d never heard of the British Restaurants that were more common in the midst of WW2 than MacDonalds are now. Where they came from, what happened in different places and the possibility of a return were all covered.
