SELECT * FROM wp_users, wp_posts WHERE wp_users.ID = wp_postts.post_author AND wp_posts.post_type = 'post' AND wp_posts.post_status = 'publish' ORDER BY wp_posts.post_date DESC LIMIT 10

Select wp_users and wp_posts to retrieve data from both tables in order to display post title, post date, author name with gravatar (gravatar isn't listed in this code)
Note: probably not idea solution, but it's one of many fixes
