A Quote by Michael Denton

Molecular biology has shown that even the simplest of all living systems on the earth today, bacterial cells, are exceedingly complex objects. Although the tiniest bacterial cells are incredibly small, weighing less than 10-12 gms, each is in effect a veritable micro-miniaturized factory containing thousands of exquisitely designed pieces of intricate molecular machinery, made up altogether of one hundred thousand million atoms, far more complicated than any machine built by man and absolutely without parallel in the nonliving world.
During the 20th century, we came to understand that the essence of all substances - their colour, texture, hardness and so forth - is set by their structure, on scales far smaller even than a microscope can see. Everything on Earth is made of atoms, which are, especially in living things, combined together in intricate molecular assemblages.
Bacteria are single-celled organisms. Bacteria are the model organisms for everything that we know in higher organisms. There are 10 times more bacterial cells in you or on you than human cells.
In my lab, we are always thinking about how cells, bacterial cells, can talk to each other and then organize themselves into enormous groups that function in unison.
I decided that the University of Sussex in Brighton was a good place for this work because it had a strong tradition in bacterial molecular genetics and an excellent reputation in biology.
Your brain is built of cells called neurons and glia - hundreds of billions of them. Each one of these cells is as complicated as a city.
It turns out all molecular and biological systems have speeds of the atoms move inside them; the fastest possible speeds are determined by their molecular vibrations, and this speed is about a kilometre per second.
Evolution, cell biology, biochemistry, and developmental biology have made extraordinary progress in the last hundred years - much of it since I was weaned on schoolboy biology in the 1930s. Most striking of all is the sudden eruption of molecular biology starting in the 1950s.
The second half of the 20th century was a golden age of molecular biology, and it was one of the golden ages of the history of science. Molecular biology was so successful and made such a powerful alliance with the medical scientists that the two together just flourished. And they continue to flourish.
Each of these [bacterial] species are masterpieces of evolution. Each has persisted for thousands to millions of years. Each is exquisitely adapted to the environment in which it lives, interlocked with other species to form ecosystems upon which our own lives depend in ways we have not begun even to imagine.
People lose fifty million skin cells every day. The cells get scraped off and turn into invisible dust, and disappear into the air. Maybe we are nothing but skin cells as far as the world is concerned.
Single cells analyze thousands of stimuli from the microenvironment they inhabit. The more awareness an organism has of its environment, the better its chances for survival. When cells band together they increase their awareness exponentially. Division of labor among the cells in the community offers an additional survival advantage. The efficiency it enables more cells to live on less. Evolution is based on an instructive, cooperative interaction among organisms and their environment enables life forms to survive and evolve in a dynamic world.
We are inhabited by as many as ten thousand bacterial species; these cells outnumber those which we consider our own by ten to one, and weigh, all told, about three pounds - the same as our brain.
Borna virus is not a retrovirus. It doesn't actually insert its own genes into our cells. What it does is just hangs out near our DNA and uses some of the molecular machinery to copy itself.
Your brain has more than 100 billion cells, each connected to at least 20,000 other cells. The possible combinations are greater than the number of molecules in the known universe.
The human brain is estimated to have about a hundred billion nerve cells, two million miles of axons, and a million billion synapses, making it the most complex structure, natural or artificial, on earth.
If you like, there is a Guinness time. The reason for that it's fundamental. It is not that we have to keep shortening the time. It turns out all molecular and biological systems have speeds of the atoms move inside them, the fastest possible speeds are determined by their molecular vibrations and this speeds is about a kilometre per second.
