A Google Groups thread have reports from some users that Google News, the home page, is not auto refreshing with news.
In the past, the page updates the news throughout the day, if you leave the page open. It seems, at least on some browsers, that Google News has stopped auto-refreshing with new news. This requires users to manually refresh the page.
Google News Guide 2 has confirmed the issue and explained they are working on a fix:
Anyone else experiencing similar issues, we've confirmed that there's a bug on our end that's preventing Google News from refreshing. We're working on a fix, and I'll get back to you as soon as there's an update.
