A Quote by John E. Walker

These studies resulted eventually in a complete sequence analysis of the complex from several species, and in the atomic resolution structure of the F catalytic domain of the enzyme from bovine mitochondria, giving new insights into how ATP is made in the biological world.
Information of fundamental importance to the general problem of atomic structure has resulted from systematic studies of the cosmic radiation carried out by the Wilson cloud-chamber method.
A great advantage of X-ray analysis as a method of chemical structure analysis is its power to show some totally unexpected and surprising structure with, at the same time, complete certainty.
It must be stressed that there is nothing insulting about looking at people as animals. We are animals, after all. Homo sapiens is a species of primate, a biological phenomenon dominated by biological rules, like any other species. Human nature is no more than one particular kind of animal nature. Agreed, the human species is an extraordinary animal; but all other species are also extraordinary animals, each in their own way, and the scientific man-watcher can bring many fresh insights to the study of human affairs if he can retain this basic attitude of evolutionary humility.
I think the history of the world suggests if one studies the Romans, and one studies the early Greeks, and one studies the history of the world, they all eventually falter if they don't come back to the basic aspect of integrity and honor and feelings of love one for another.
It reflects a prevailing myth that production technology is no more amenable to human judgment or social interests than the laws of thermodynamics, atomic structure or biological inheritance.
A new species is being born inside each one of us. Eventually, we will all express the perceptions and values of this new species.
Could it be that the atomic isolation of the husband and wife nucleus with an orbiting child or two is in fact a culturally imposed aberration for our species? As ill-suited to our evolved tendencies as corsets, chastity belts, and suits of armor? ...a distorted and distorting family structure inappropriate for our species?
I think that Rodney Stark studies of new religious movements in the modern world give us some insights into the kinds of questions that we can ask about early Christianity.
I try to think up material that might apply to the subjects they are studying. How many mitochondria does it take to power a cell? One. Because mitochondria are the powerhouse of the cell. Not ready for prime time, that one.
This work made me more and more interested in biological matter, and I decided that I really wanted to work on the X-ray analysis of biological molecules.
In Darwin's time all of biology was a black box: not only the cell, or the eye, or digestion, or immunity, but every biological structure and function because, ultimately, no one could explain how biological processes occurred.
Studies in the emerging field of cellular bioenergetics, a branch of biochemistry concerned with how energy flows through living systems, suggest that molecules from orchids might be able to repair decaying mitochondria, the powerhouses of cells, in humans.
Dogs are not 'people' of another species. They are another species. To train and care for them properly, to show them how to live in our complex world, requires first and foremost that we understand that.
Historically, very few discoveries were made out of thin air. Most of the greatest insights depended upon the intellectual ecology in which the scientists lived. A certain critical mass of "new findings" occurred, and bright people all over the world found out about it, and several read the tea leaves the same way.
Biological energy comes from the sun. Light energy harvested by photosynthesis in chloroplasts and phototropic bacteria becomes stored in carbohydrates and fats. This stored energy can be released by oxidative metabolism in the form of adenosine triphosphate (ATP) and used as fuel for other biological processes.
But sequence comparisons simply can't account for the development of complex biochemical systems any more than Darwin's comparison of simple and complex eyes told him how vision worked.
