This month sees the tenth anniversary of the launch of the British Psychological Society's Research Digest.

It has come a long way since the first fortnightly email newsletter was distributed on 1 September 2003 to a handful of readers. Today the email reaches over 30,000 subscribers and the award-winning Research Digest blog (launched in '05) attracts hundreds of thousands of page-views a month.

Together with its presence on Twitter and Facebook, the Research Digest is now one of the most popular and trusted sources of psychology research news in the world.

To mark the anniversary, this week the Digest is delving into its archive and publish a series of six "self-help" posts, based on past items, that have practical lessons for real life, starting today with evidence-backed tips on studying.
