British biophysicist and x-ray crystallographer helped discover DNA’s structure but controversially missed out on Nobel prize.

The latest Google doodle celebrates the life and work of British biophysicist and x-ray crystallographer Rosalind Franklin, whose research led to the discovery of the structure of DNA.

Franklin was born in Notting Hill, London on 25 July 1920.

The second “o” in the doodle contains her image, while the “l” has been replaced with the DNA double helix.

Franklin also made critical contributions to our understanding of the molecular structures of RNA, viruses, coal and graphite.

She died from ovarian cancer in April 1958, aged just 37.

The scientist has perhaps become best known as “the woman who was not awarded the Nobel prize for the co-discovery of the structure of DNA”.

During her DNA research, Franklin worked at King’s College London under Maurice Wilkins.

The story goes that he took some of her x-ray crystallography images without her knowledge and showed them to his friends, Francis Crick and James Watson, who were also trying to discover the structure of DNA.

Wilkins, Crick and Watson were awarded the Nobel prize in Chemistry in 1962.

Crick later acknowledged that Franklin’s images were “the data we actually used” to formulate their 1953 hypothesis regarding the structure of DNA.

The most significant of those images is known as Photo 51, which is also the inspiration for an exhibition currently at Somerset House in London.

Podcast: nature

natureNature werd niet geschapen op 23 oktober 4004 v.o.t., maar op 4 november 1869. Ondertussen is het magazine uitgegroeid tot een van de meest geciteerde interdisciplinaire wetenschappelijke tijdschriften op deze aardbol. Voor de boeiende geschiedenis van het blad, de hoogtepunten en de missers, kan u terecht op de geschiedenispagina van Nature, of in het archief.

Fast forward naar nu, vooral omdat ik de nature podcast onder de aandacht wil brengen. Korte afleveringen, normaliter een klein half uur, met interessante interviews en besprekingen, worden afgewisseld met speciale episodes en boeiende historische interviews.

Een paar recente korte inhouden, om u een idee te geven, hoewel ik u aanraad om dit hier te negeren en direct naar het archief van de podcast te surfen.

  • Podcast Extra: Many physicists are happy with the idea that time doesn’t exist. Now a new book, Time Reborn by Lee Smolin, wants to put time back into physics.
  • 30 May 2013: This week, mosquitoes that can’t smell humans, a new birdy dinosaur shakes the bird family tree, and what makes a planet habitable?
  • 23 May 2013: This week, the man who sent spacecraft to the edge of the solar system, our skin’s fungal friends, and Neanderthal childhoods.
  • Nature PastCast – May 1985: Jonathan Shanklin was sifting through a backlog of data when he made the startling discovery of a hole in the ozone layer above Antarctica. In this podcast, he and others recall events in the mid-1980s and discuss how the ‘ozone hole’ became the poster child for environmentalism.

Mijn persoonlijke favoriet is het interview met Raymond Gosling, die o.a. samengewerkt heeft met Rosalind Franklin en Maurice Wilkins. Goslin, 87, blikt terug op zijn rijke carrière. Hij vertelt over de ontdekking van de structuur van DNA en legt uit waarom de namen Crick en Watson wél een bel doen rinkelen. Zet u in uw zetel, neem een glas wijn en laat u meevoeren naar het Cambridge van de jaren 50, onder en boven de Thames. (Listen now,Download mp3).
