Last year, Venkatraman 'Venki' Ramakrishnan won the Nobel Prize in Chemistry for discovering how the ribosome works. The method he uses has helped a lot of other scientists Maurice Wilkins, Linus Pauling and Dorothy Hodgkin win the Prize too. It's called Crystallography.
A woman scientist from Cambridge University published an article in the April 25, 1953 on the journal Nature about the molecular structure of DNA. However two male scientists had written another article on the same subject in the same issue of the magazine. Those male scientists - Francis Crick and James Watson - got all the credit. The woman, Rosalind Franklin, vanished into history.
Women have often had a tough time in science - first getting jobs, and then getting enough recognition for their research. Kathleen Lonsdale's life is a great inspiration to girls who want to become scientists. She showed they are as good (or even better) than boys.
