got a 403 error.. It could be accessed with read_url.
The below recipe works but images fail with 403.

            feeds.append((section, articles))
        return feeds
I made changes and tried something but got a I got a TypeError
should i've not used index_to_soup with read_url
File "<string>", line 66, in parse_index
File "calibre\web\feeds\news.py", line 731, in index_to_soup
TypeError: science.open() got an unexpected keyword argument 'timeout'
