Your feed url has ' and that breaks the string. Enclose the feed url with double quotes like this:
Code:
feeds = [(u"Alzheimer's Research News", u"yourfeedurl")]
and adding more feeds:
Code:
feeds = [
(u"Alzheimer's Research News", u"yourfeedurl")
,(u"bbb", u"yourfeedurl")
,(u"ccc", u"yourfeedurl")
]
