I am happy to report Mico Tatalovic that we were selected as the 2nd best student magazine in the country by the Guardian Student Media Awards last November. Managing editor This wasn’t the first time we were nominated for the best student Jovan Nedic magazine, though. Back in 2005, when the publication first be- gan, after just two issues we received our first nomination. Three years later, we were among the top five again, but this time we Editorial Team gained a ranking at second place. This is quite an achievement Jacob Aron given that I, Science is a specialist magazine covering what many Jessica Bland people see as a niche area of interest. As far as I am aware this Julia Bracewell is the first time any student science magazine has ever won such Umar Chaudhry an award. This should assure you, the reader, of the quality of the Jessica Hamzelou magazine you are holding in front of you and should also leave Umia Kukathasan us all feeling optimistic about the future of science journalism. Emma Quilligan In keeping with the tradition of the best student science journalism we bring you another ex- citement-packed issue covering various scientific and medical issues. Exploring the unexplored, Olivia Sharp we examine the unlikely bed fellows that are science and pornography. Refusing to be same as Chloe Sharrocks all the others by presenting you with yet another article on Charles Darwin and evolution we do Sam Wong something different to celebrate the 150th anniversary of his book On the Origin of Species: we bring you the story of his ancestor, the unsung hero that was Erasmus Darwin. We also look into Contributors why bees are dying across the planet: we investigate the menace of Colony Collapse Disorder. In Jessica Bland Stringing us Along we explore the science and philosophy of string theory: is this the theory that Maria Hogan will explain everything, and how can we know this if we cannot test it yet? For all the joggers and Catherine Jones runners out there we look into the best substrate to run on for your bones and joints. And finally, Tim Jones we bring you the amazing medical story of a Haitian boy who was saved by modern medicine and Flora Mactavish the will of good people willing to reach out and help others in distress. Alongside these features we also cover a variety of events, films and magazines in our reviews Geoffrey Marsh section. Enjoy your read!
