Few News available?

I searched News for astra zeneca and the newest news was from 2021-04-30 10:46:52. Bing has some news, but they are not in a scope like images: https://www.bing.com/news/search?q=astrazeneca&qpvt=astra+zeneca. Maybe there are ways to add some sources like https://tagesschau.de https://www.dw.com https://spiegel.de. How about a minisearcher?
