Well it’s April the first, and that means it’s time for some science-related pranks. Here’s the pick of the jokes from across the Interweb.

The Large Hadron Collider has taken the crown this year. To get things rolling, CERN put out its own bogus press release on the giant collider (which started just a few days ago), claiming that they had discovered a “prehistoric particle”.

London’s the Telegraph ran their joke a few days early (and unintentionally) by falling for the good ol’ Large Hardon Collider typo. Competitor the Independent has a more inventive joke, an exclusive report on plans for building LHCII around London’s notoriously slow circle line:

It would mean that two beams of protons would be travelling in clockwise and counterclockwise directions at 99.999999 per cent of the speed of light, within feet of Circle line passengers stuck in perpetual immobility.

Meanwhile Resonaances blogger Adam Falkowski gets the prize for most believable April fools prank for his announcement of the discovery of supersymmetry, in the form of everyday muons (Adam, if you’re reading this, your post did make me double-check with CERN, so well done).

A more abstruse LHC joke can be found on ArXiv, along with a few other super nerdy pranks. The best of the bunch include a new way to survey zombies without infecting the authors, and a bibliometric study by Zuntz, Zlosnik, Zunckel, and Zwart showing that people whose names appear at the end of the alphabet produce superior science.

Finally, we would be remiss for not mentioning our competitor has announced an unlikely merger. Special props to their art department.
