Facebook has taken the wraps off a new search function dubbed "Graph Search" that indexes the social network by people, photos, places and interests as it looks to boost user engagement on the site.
The new feature will allow users to make queries on the site such as "photos of my friends in 2001", "restaurants nearby" or "who are my friends who like Guinness World Records".
Facebook currently holds the Guinness World Records title for largest online social network, boasting one billion monthly active users as of 4 October 2012, with more than 140 billion "friend" connections between them, and over 219 billion photos having been uploaded to the site.
Meanwhile, investigations are under way to try to find out how beefburgers on sale in UK and Irish Republic supermarkets became contaminated with horsemeat.
Irish food safety officials, who carried out tests two months ago, said the products had been stocked by a number of major supermarket chains across the UK.
The world's rarest horse breed is the Abaco Barb. By July 2010, only five individuals existed, all of which were apparently infertile. Once common in the Bahamas, the breed's demise is believed to be due to hunting for food and sport, as well as to poisoning by farming pesticides.

Finally, Police in the UK have launched an appeal for information after a limited edition Ferrari worth £230,000 was stolen in a daring robbery from a showroom in Surrey.
