Ladles and gentlespoons, the results are in. We had an amazing response, and after sifting through a mass of #sci140-tagged tweets, discarding all the retweets and publicity (and a huge thank-you to everyone who spread the word), we had 197 unique entries (grep saved my life).

Many of you posted very witty ‘historical’ paper summaries, but there were several who managed to squeeze their own papers into 140 133 characters too. This, I think, was far more difficult, even if it did not lend itself so readily to humour.

It turned out to be quite an interesting social experiment, too. There were a number of themes, possibly the most popular being the structure of DNA (not surprising seeing as most of my twitfriends are at least vaguely biochemical). This from @SelectAgent was one of the best:

Salt of DNA structure= double helix. Strands anti-parallel; has implications. (PS Rosie didn’t help)

Physics, especially quantum mechanics, also featured heavily, and @pssalgado deserves a special mention for

Where are you, Heis? “Don’t know exactly, but I can tell you how fast I’m going!”

Galileo was another favourite among physicists, @sciencebase almost scooping the prize with

Dropped heavy and light ball at Pisa; saw landed at same time. Peer review problems now, especially after telescope incident.

Many entries had fun with Mendel; here’s @marymulv:

Peas for tea. Again! (Damn that gardener.) Smooth, wrinkly, smooth… Is that a pattern? Hm. Should I tell that Darwin fellow??

Stanley Milgram was the subject of a couple of tweets, @sciencebase again making me laugh with

Stanley, is this circuit really 450 Volts, those people look like they’re in real pain? Shut up and just push the lever

Some of you are obviously budding behavioural psychologists, as Pavlov’s famous experiment also attracted a lot of attention? My favourite? @enniscath‘s

Rang bell, fed dogs. Rang bell again, dogs drooled. NO FOOD FOR YOU! BAD DOG! (heh heh. Stoopid dogs).

Honorable mentions should also go to silentypewriter and yokofakun for sheer wit and volume dedication.

But there can be only one winner, I’ve decided. For his poetic take on Watson & Crick’s structure of DNA, and for a smart paper of his own, the winner of the #sci140 competition is…

@CameronNeylon (Cameron Neylon)

The winning entries from Cameron are

Take bacterial cell wall chemistry. Replace proteins + wall with any prot + beads. Easy protein labelled beads! (link)

and

2 interwound helices, with handedness right, and a 3.4 pitch, and hydration just right + keto not enol or they don’t zip up right (link)

A bag full of f1000 goodies will be winging its way to him very shortly.

Mad props to Cameron, and a big thank you to everyone who participated. It was such good fun, I rather think we might run something like this again. Keep an eye on @f1000 on Twitter for the next one. The full list of #sci140 entries are below the fold.
