rss feed not updating

I’m using the rss widget in Atalualpa from Environmental Health News. The rss feed has not updated since I first installed it. My site is http://ohiocitizen.org/ the rss url is http://www.environmentalhealthnews.org/archives_rss.jsp?tn=1title,lede,description,text,subject,publishername,coverage,reporter&tv=Ohio&ss=1

I’m wondering what’s wrong. Thanks.
