The story behind DNA’s double helix

The notorious race to uncover the structure of DNA, the molecule of inheritance, began in 1951, when American biologist James Watson  arrived at the University of Cambridge. Here he met Francis Crick, an English physicist and the two began building scale models to test their ideas of what DNA’s appearance might be.

Meanwhile, two scientists at King’s College London called Maurice Wilkins  and Rosalind Franklin were also studying DNA. They were attempting to crystallise the molecule to make an x-ray pattern of it. They hoped this would provide important clues about its structure.

Although the two institutions were effectively competing against each other, Francis Crick (University of Cambridge) and Maurice Wilkins (King’s College London) communicated regularly. Letters sent from Wilkins to Crick reveal their close personal relationship.

It was Rosalind Franklin’s famous x-ray image, nicknamed ‘Photo 51’, that finally revealed the structure of DNA in May 1952. The pattern appeared to contain ‘rungs’, like those on a ladder, set between two strands. The fuzzy “X” pattern indicated DNA’s helix shape. In early 1953, Wilkins showed Watson the image, seemingly without Franklin’s knowledge.

Thor 2: The Dark World 

what are you willing to sacrifice?

#the old empire will crumble; beneath the pride of odin; the madness of loki; the humanism of thor     #all of them stripped bloody and bare to the tides of war; with the mortals creeping up behind     #staring into space now and knowing what’s out there; and how dangerous they can be with that knowledge     #and the fear that knowledge gives     #with the breaking of the bifrost the very spine of asgard’s rule is already broken; and the worlds are mustering     #muttering; rebellious; rising in the dark     #asgard cannot hold now; not ever again as they were; sure in their glory and gold     #and thor; the living embodiment of golden asgard; will strip his godhood from his bones and rise as something strange and new     #like asgard itself must     #and loki will be the mechanism; the hinge; the catalyst to the burning and the flaying of his brother     #for love and for loathing and for the chaos he cannot unbind from his own bones     #thor     #loki     #thor 2     #the rise and fall of empires

1920’s Hairstyles
A collection of 1920’s photographs, depicting some of the hairstyles of the time, like the kiss curl, the orchid bob, the charleston cut, coconut bob, earphones hairstyle, cottage loaf (bun) and popular styles you’ll probably never see in a period drama like extreme windblown style, the frizzy hairstyle and the Poodle cut.

I wish quite a few of these would come back, not just with hipster type girls who think they are unique because they are into burlesque cabaret fashion or in a band that does that sort of thing.

Gosh, I love these. If I knew how to style my own hair I would attempt some of these for myself.
