Now for your weekly fix of Google news. Google and Yahoo have decided to further delay their controversial search-advertising deal following the announcement of investigation by the US Department of Justice.

The agreement, announced just after Microsoft‘s bid for Yahoo fell apart, will let Yahoo run Google ads with Yahoo’s search results and on some Yahoo sites in the US and Canada. Critics have believe the deal will hurt competition and lead to higher prices, since Google and Yahoo hold the top two market-share positions in search.

“When we announced our advertising agreement with Yahoo in June we agreed to delay its implementation until October to give regulators time to look at the details,” a Google spokesperson explains, “As we are still in conversation with the Department of Justice, we have agreed to a brief delay in implementing the agreement while those discussions continue.”

Still in Googleland, the company has decided to adapt its free email service to help people who have a tendency to send drunken emails that they wake up to regret.

Mail Goggles software starts automatically after dark and on weekends, when people are at there most likely to send intoxicated emails and requires that five simple math problems be answered correctly in less than a minute in order to send.

“Sometimes I send messages I shouldnt send,” Gmail engineer Jon Perlow says, “Like the time I told that girl I had a crush on her over text message. Or the time I sent that late night email to my ex-girlfriend that we should get back together.”

Imagine the great wars that could have been prevented if this application could be used in everyday conversations.
