Shimon Sandler reports that Google Real Estate was launched recently. When searching "houses for sale" in a regular Google search, some users might see a one-box that helps narrow down what type of house they are looking for.
This isn't really a new service per se, but it shows another example of how Google Base items are starting to show up in regular Google result pages. There have been numerous other examples of this type of thing -- Danny Sullivan at Search Engine Watch has a great article about them "Google Recipes! Google Careers! Google Confusion! The UI Madness Continues".
