How Crick and Watson deciphered the DNA

How Crick and Watson deciphered the DNA

On February 28, 1953,  American molecular biologist James D. Watson and English biophysicist Francis Crick announced to friends that they succeeded to determine the chemical structure of DNA. “When finally interpreted, the genetic messages encoded within our DNA molecules will provide the ultimate answers to the chemical underpinnings of human existence.” – James D. Watson, in [11] DNA and RNA – the Prelude In 1869, the Swiss physician Friedrich Miescher discovered a…

Oswald Avery and the Avery-McLeod-McCarthy Experiment

On February 1, 1944, physician and medical researcher Oswald Avery together with his colleagues Colin MacLeod and Maclyn McCarty announced that DNA is the hereditary agent in a virus that would transform a virus from a harmless to a pathogenic version. This study was a key work in modern bacteriology. Prelude – The Griffith Experiment The achievement by the scientists Avery, MacLeod, and McCarty were based on Frederick Griffith’s studies on bacteria,…

Frederick Sanger and the Structure of Proteins

Frederick Sanger and the Structure of Proteins

On August 13, 1918, British biochemist Frederick Sanger was born. In 1958, he was awarded a Nobel Prize in chemistry “for his work on the structure of proteins, especially that of insulin“. In 1980, Walter Gilbert and Sanger shared half of the chemistry prize “for their contributions concerning the determination of base sequences in nucleic acids“. “Scientific research is one of the most exciting and rewarding of occupations. It is like a…

Peter Debye – Dipole Moments, X Rays, and Light Scattering

Peter Debye – Dipole Moments, X Rays, and Light Scattering

On March 24, 1884, Dutch-American physicist and physical chemist Peter Joseph William Debye was born. Debye’s investigations of dipole moments, X rays, and light scattering in gases brought him the 1936 Nobel Prize in Chemistry. Most of his work was in chemical-physics with special interest in electrolytes and dipolar momentum analysis. He established a theory of specific heat with some improvements on that proposed by Einstein.[5] “If a problem is clearly stated,…

Mark Weiser and his vision of Ubiquituous Computing

Mark Weiser and his vision of Ubiquituous Computing

On July 23, 1952, computer scientist Mark David Weiser was born. Weiser was chief scientist at Xerox PARC in the United States and is widely considered to be the father of ubiquitous computing, a term he coined in 1988. In contrast to desktop computing, ubiquitous computing can occur using any device, in any location, and in any format. A user interacts with the computer, which can exist in many different forms, including laptop computers,…
