This week on Science Weekly, with Kevin Fong standing in for Alok Jha while he's in Antarctica, we take a look at the big science stories of 2013.

Kevin is draws upon the hive brain of the Observer and Guardian science team, namely Observer science editor Robin McKie, Observer Tech Monthly commissioning editor Nicola Davis and Guardian science correspondent Ian Sample.

Including major advances in decoding ancient DNA, a joint Nobel Prize in Physics for the theory that led to the discovery of the Higgs boson, the first beefburger grown in the lab (funded by Google co-founder Sergey Brin), the return of a king, a 3D-printed gun, the Chelyabinsk meteorite, and Voyager 1 leaving the solar system, it has been a momentous year for science.
