Hello, Dan,
what I could come up with so far:
IQ - Science and Research
This is a podcast I like to listen to.
Patric Heizmann
Patric Heizmann gives very good tips on sports, health and healthy nutrition. He often interviews experts on the subject. He also has a podcast. Enter his name in the search function and you should find him.
kenfm.de
This is an alternative medium. It is mainly about politics and socio-political topics. Very good alternative or at least a very good addition to the mainstream media, which in my opinion conceal a lot and therefore present reality in a very distorted way.

This is a series of broadcasts about real operations of fire and rescue services in Germany. I think that's a great show. You can see what a great job the fire brigade does and what nice people they are.
