Furthermore, recent collaborative studies have showed the relationship between accelerated telomere shortening and life stress and that low telomerase levels are associated with six prominent risk factors for cardiovascular disease. In 1628 Harvey published An Anatomical Study of the Motion of the Heart and of the Blood in Animals, which explained how blood was pumped from the heart throughout the body, then returned to the heart and recirculated. “Natural selection” was claimed by Darwin virtually to be the cause of evolution, and in his use of the phrase in the book “Origin of Life”; he gives it the power of the Creator. Harvey was fascinated by the way blood flowed through the human body. Served as dept. Found that someone else gave this as an answer.. For this work she was awarded the 2009 Nobel Prize in physiology, sharing it with Carol.W.Greider and Jack.W.Szostak. In my day I was told women didn’t go into chemistry. They used their expertise in developing our local industries, preserving our natural resources, increasing agricultural production, saving biodiversity, and improving the lives of our poor countrymen.

He also serves as the Alexander Rich Distinguished Investigator at Massachusetts General Hospital in Boston. The history of molecular biology begins in the 1930s with the convergence of various, previously distinct biological and physical disciplines: biochemistry, genetics, microbiology, virology and physics.With the hope of understanding life at its most fundamental level, numerous physicists and chemists also took an interest in what would become molecular biology. Elion never married, had no children, and listed her hobbies as photography, travel and listening to music.

This resulted in the well-known phrase survival of the fittest, where the organisms most suited to their environment had more chance of survival if the species falls upon hard times. German biologist and scientific explorer. He argued that global currents tended to flow from east to west, and continents eroded on their eastern borders with the material carried across to be deposited on the western borders. Elion had moved to the Research Triangle in 1970. She completed her graduation from Hunter College with a B.A.degree in chemistry in 1937.

It was rare to have aboard a sailing vessel of the early 19th century a person who could read and write, let alone one, such as Darwin, who could appreciate the necessity of applying scientific principles to the business of gathering data and carrying out research on it.

Thus, depending on cell type telomerase partially or completely counteracts the progressive shortening of telomerase that otherwise occur. Using the crescograph, he further researched the response of the plant to fertilizers, light rays and wireless waves. Darwin believed that organisms had ‘evolved’ to suit their environments, and occupy an ecological niche where they would be best suited to their environment and therefore have the best chance of survival.
