Natural rubber becomes crystalline when stretched or when cooled, yet the structure of this ordered form has never been satisfactorily determined. We have used film-recorded fiber X-ray diffraction data from oriented unvulcanized natural rubber, comb

Early X-ray diffraction patterns from oriented fibres indicated that DNA must have a simple, repetitious structure and encouraged some researchers, who were already convinced that DNA was the genetic material, to undertake more detailed diffraction a

Maurice Hugh Frederick Wilkins was the 'Third man of the double helix; according to the publishers who were allowed to foist this title on his late-written autobiography. Certainly it is for his role in the discover of the duplex secondary structure

The molecular structure of poly (I)•poly (A)•poly (I) has been determined and refined using the continuous intensity data on layer lines in the x-ray diffraction pattern obtained from an oriented fiber of this polymorphic RNA complex. The polymer

Native, general sequence B-form DNA in uniaxially oriented fibers is a ten-fold helix with identical antiparallel strands: this is to say the molecular symmetry is 2 2 101. The diffraction patterns indicate that local variations, however significant,

John Monteath Robertson (JMR), pioneering chemical crystallographer, died at Inverness in December 1989, seven months before his 90th birthday, 20 years after retiring from the Gardiner Chair of Chemistry and the Directorship of the Chemical Laborato

Substantial growth of universities, whether by internal changes in staff and student populations, or by inter‐institutional mergers raises the question of whether significant economies of scale can be expected. Evidence is emerging that the reverse
