The 300-million-year-old forest is the largest ever uncovered, providing an unprecedented look at the ecology of one of Earth's earliest tropical forests

Web-based email has made quite the comeback in the past few years thanks to massive increases in email storage offerings, as well as revamped user interfaces. However, it appears that all of the big players have run into some problems actually keeping email systems online. This past week there have been stories of both AOL and Yahoo losing a ton of email (thousands of emails for AOL, millions for Yahoo Japan). This comes just a few months after Google had some problems with mass email deletions in Gmail. While the convenience these services provide is fantastic, all of these stories of lost emails should act as a reminder that you probably shouldn't trust any of these providers alone to care for your email. It's almost surprising that we haven't seen more of an effort by these or other providers to position email backup services as well, promising to keep you running, should your main account get knocked out or deleted.
