Earlier today at Mountain View, Google used Press Day to announce the launch of a bunch of new widgets. The latest version of Desktop (4), Google Co-op, Google Notebook and Google Trends.
Google Trends does comparisons of searches over time and the impact various news stories had on those numbers. This could be a handy tool for search research.
Google Desktop is now in its fourth version.
Google Co-op is an interesting community builder with human input ad review - this could have all sorts of impact on search results over the next few years.
Google Notebook is not out of beta yet but will be soon and it promises to provide the ability to attached notes to a web page - well sort of like a sticky that is assigned to a particular website with notes that can then be kept and even emailled to friends and colleagues.
