Rosalind Franklin, The Dark Lady of DNA
#sciencesunday curated by +Allison Sekuler and +Robby Bowles
The award winning biographer Brenda Maddox records the biography of Rosalind Franklin in her book titled ‘Rosalind Franklin, The DarkLady of DNA’ where she portrays Franklin as a determined perfectionist, single minded and forthright, whose work had not been given due recognition for the discoveryof the double helix structure of DNA.
Franklin’s X-ray diffraction photographs of DNA and her precise measurements of the unitcell (the smallest repeating unit) of DNA showed unmistakable evidence of a helical structure, clearly demonstrating that DNA was a doublehelix. This finding contradicted the view held at the time by Watson and Crick, regarding the structure of the DNA molecule.
In 1962 Watson, Crick and Wilkins were awarded the Nobel Prize for the discovery of DNA leavingout Franklin from the greatest scientific discovery of the 20th century. Rosalind Franklin died of ovarian cancer in 1958, (probably her carelessness when handling the x-ray crystallography equipment was a contributory factor). She died not knowing that her work had been crucial forthe discovery of the double helix structure of DNA.
The Nobel Prize is awardedonly to those who are still alive, and it was four years after her death that Watson, Crick, and Wilkins received the award. Though Franklin was not eligible,many share the thought that she deserved explicit mention at the time of receiving the award by the other three scientist.
At a time when the achievement of women scientists were undermined and overlooked Rosalind Franklin carried on regardless, and accomplished much in her field. She was a scientist of the highest calibre,one who devoted her life to science.
The crucial x-ray diffraction image "Photo 51" is shown here.

Satélite artificial estadounidense
satélite
A pesar de que desde Nicolás Copérnico (1473-1543) sabemos que la Luna es satélite de la Tierra y que muchos otros planetas, como Júpiter o Saturno, tienen los suyos, lo cierto es que esta palabra se hizo de uso cotidiano sólo a partir de 1957, cuando la Unión Soviética puso en órbita el primer satélite artificial, el Sputnik I. Pocos imaginaban por entonces que aquella novedad —vista por entonces como una hazaña tecnológica, pero sin mayores consecuencias prácticas— tendría una importancia tan fundamental en las telecomunicaciones y en la vida cotidiana del mundo de hoy.
El vocablo español proviene del latín satelles, satellitis, tomado del etrusco y usado por los romanos para designar a los soldados de la escolta personal de un rey, príncipe o emperador. Según una leyenda romana, el primer gobernante que tuvo guardaespaldas fue el último rey de Roma, Tarquino el Soberbio (534-509 a. de C.). Posteriormente, por una bella metáfora, la palabra pasó a designar, aún en latín, los cuerpos celestes que orbitan en torno de algunos planetas.
