Top 212 Molecular Quotes & Sayings - Page 3

Polymeric materials in the form of wood, bone, skin and fibers have been used by man since prehistoric time. Although organic chemistry as a science dates back to the eighteenth century, polymer science on a molecular basis is a development of the twentieth century.

Music is everything; without it, we [people] are nothing. We're just living vibrations of molecular tinglings, and without music we'd explode into nothing and go down a quantum hole.

In 1995, I founded The Molecular Sciences Institute with a gift from the Philip Morris Company where I hoped that we could create an environment where young people could pursue science in an atmosphere of harmonious purpose and high intellectual challenge.

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.

Biology is far from understanding exactly how a single cell develops into a baby, but research suggests that human development can ultimately be explained in terms of biochemistry and molecular biology. Most scientists would make a similar statement about evolution.

Studying organisms at a molecular level was totally compelling because it was moving from being a naturalist, which was the 19th-century kind of science, to being very focused and really getting to the heart of these molecules.

We live in the hope and faith that, by the advance of molecular physics, we shall by-and-by be able to see our way as clearly from the constituents of water to the properties of water, as we are now able to deduce the operations of a watch from the form of its parts and the manner in which they are put together.

The other advantage is that in conventional manufacturing processes, it takes a long time for a factory to produce an amount of product equal to its own weight. With molecular machines, the time required would be something more like a minute.

Reductionist ideology not only hinders biologists from thinking adequately about the phenomena we wish to understand: it has two important social consequences: it serves to relocate social problems to the individual rather than exploring the societal roots and determinants of a phenomenon; and second, it diverts attention and funding from the social to the molecular.

A renaissance in cellular biology has recently revealed the molecular mechanisms by which thoughts and perceptions directly influence gene activity and cell behavior...Energy psychology, through its ability to rapidly identify and reprogram limiting misconceptions, represents the most powerful and effective process to enhance physical and emotional well being.

There's that effect that is very physical, very down there at the synaptic level, which really means microscopic cellular level, but also molecular level, because all of those structures are operating on an electrochemical basis and so the changes there are very important.

The machine code of the genes is uncannily computer-like. Apart from differences in jargon, the pages of a molecular biology journal might be interchanged with those of a computer engineering journal.

In your letter you apply the word imponderable to a molecule. Don't do that again. It may also be worth knowing that the aether cannot be molecular. If it were, it would be a gas, and a pint of it would have the same properties as regards heat, etc., as a pint of air, except that it would not be so heavy.

Cheetah genes cooperate with cheetah genes but not with camel genes, and vice versa. This is not because cheetah genes, even in the most poetic sense, see any virtue in the preservation of the cheetah species. They are not working to save the cheetah from extinction like some molecular World Wildlife Fund.

Cancer's life is a recapitulation of the body's life, its existence a pathological mirror of our own. Susan Sontag warned against overburdening an illness with metaphors. But this is not a metaphor. Down to their innate molecular core, cancer cells are hyperactive, survival-endowed, scrappy, fecund, inventive copies of ourselves.

Cancer is like the common cold; there are so many different types. In the future we'll still have cancer, but we'll detect it very, very early, so that it won't kill anybody. We'll zap it at the molecular level decades before it grows into a tumor.

The large-scale homogeneity of the universe makes it very difficult to believe that the structure of the universe is determined by anything so peripheral as some complicated molecular structure on a minor planet orbiting a very average star in the outer suburbs of a fairly typical galaxy.

Even present-day fuels possess more than enough energy, if only we knew how to release and use it. Just as molecular energy is so freely used to-day, so atomic energy may bring interplantary travel within easy reach to-morrow.

The mystical perception (which is only "mystical" if reality is limited to what can be measured by the intellect and senses) is remarkably consistent in all ages and all places. All phenomena are processes, connections, all is in flux...have the mind screens knocked away to see there is no real edge to anything, that in the endless interpenetration of the universe, a molecular flow, a cosmic energy shimmers in all stone and steel as well as flesh.

These days vampires gravitated toward particle accelerators, projects to decode the genome, and molecular biology. Once they had flocked to alchemy, anatomy, and electricity. If it went bang, involved blood, or promised to unlock the secrets of the universe, there was sure to be a vampire around.

My cooking philosophy, what I try to do, is to make a cuisine where the produce and the product shines, compared to some current trends that are maybe more adding additional things, like molecular cuisine, with a lot of additives and chemicals, which are now showing that they could be bad for your health.

The big idea we start with is: "How is the genome interpreted, and how are stable decisions that affect gene expression inherited from one cell to the next?" This is one of the most competitive areas of molecular biology at the moment, and the students are reading papers that in some instances were published this past year. As a consequence, one of the most common answers I have to give to their questions is, "We just don't know."

Society flourishes when and only when its molecular unit, the family, flourishes. We know that lasting improvement comes only in the small increments produced by individuals adhering to the simple rules of life.

There is no publication in the scientific literature - in prestigious journals, specialty journals, or books - that describes how molecular evolution of any real, complex biochemical system either did occur or even might have occurred.

We know evolution happened not because of transitional fossils such as A. natans but because of the convergence of evidence from such diverse fields as geology, paleontology, biogeography, comparative anatomy and physiology, molecular biology, genetics, and many more.

Molecular genetics, our latest wonder, has taught us to spell out the connectivity of the tree of life in such palpable detail that we may say in plain words, "This riddle of life has been solved."

I am a spectator, so to speak, of the molecular whirlwind which men call individual life; I am conscious of an incessant metamorphosis, an irresistible movement of existence, which is going on within me - and this phenomenology of myself serves as a window opened upon the mystery of the world.

According to the belief, molecules closer together than 200 nanometers could not be told apart with focused light. This is because, in a packed molecular crowd, the molecules shout out their fluorescence simultaneously, causing their signal, their voices, to be confused.

The language of God is not English or Latin; the language of God is cellular and molecular.

Most people don't really like to pose. It is difficult to get them to be present and relaxed under this kind of molecular scrutiny. I want them to understand I'm not simply painting them: I am painting them within a precise moment in time, as a shadow moves across their eyebrows. Then it is gone. The moment is over.

When we consider the fact that nearly three-quarters of the surface of the globe is covered by oceanic water, we begin to realise that the molecular scattering of light in liquids may possess an astronomical significance, in fact contribute in an important degree to the observed albedo of the earth.

It's terrifying the way molecular biology has become more and more jargon ridden. But I strongly believe that my book can be read by the intelligent layman. I want everyone who bought a copy of 'A Brief History of Time' to buy a copy of 'Genome'.

I am the life-force power of the universe. I am the life-force power of the 50 trillion beautiful molecular geniuses that make up my form, at one with all that is.

A potato can grow quite easily on a very small plot of land. With molecular manufacturing, we'll be able to have distributed manufacturing, which will permit manufacturing at the site using technologies that are low-cost and easily available.

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.

A paradigm shift is the best a scientist can hope for. Whenever I smell an opportunity like that, I go after it. You have a new discovery that something's working in a different way than you thought. And this is particularly true in molecular and cell biology, which is structural biology and has the least potential for controversy and partisanship among the biological scientists. You're dealing with a concrete object that's either there or not there.

I would say that molecular gastronomy is a field of science. I would - I would say that it's probably lumped under chemistry, maybe. Because cooking, while it has certainly biology and some physics, it's mostly chemistry.

My lab looks at the ability of stress hormones to kill brain cells, and basically we are trying to understand on a molecular level how a neuron dies after a stroke, a seizure, Alzheimer's, brain aging, and what these stress hormones do to make it worse.

Give us detailed, testable, mechanistic accounts for the origin of life, the origin of the genetic code, the origin of ubiquitous bio macromolecules and assemblages like the ribosome, and the origin of molecular machines like the bacterial flagellum, and intelligent design will die a quick and painless death.

I knew, however, that it would cost ten times what I had available in order to build a molecular beam machine. I decided to follow a byway, rather than the highway. It is a procedure I have subsequently recommended to beginning scientists in this country, where research strategy is best modelled on that used by Wolfe at the Plains of Abraham.

The students of biodiversity, the ones we most need in science today, have an enormous task ahead of molecular biology and the medical scientists. Studying model species is a great idea, but we need to combine that with biodiversity studies and have those properly supported because of the contribution they can make to conservation biology, to agrobiology, to the attainment of a sustainable world.

In physics, one of the most exciting areas is in nanotech. With computers exhausting the power of silicon, Silicon Valley could become a Rust Belt, unless we can find replacements, such as quantum computers and molecular computers. To be a leader in any field, one has to have a great imagination. Sure, we have to know the basics and fundamentals. But beyond that, we have to let our imagination soar.

Nature - how, we don't know - has technology that works in every living cell and that depends on every atom being precisely in the right spot. Enzymes are precise down to the last atom. They're molecules. You put the last atom in, and it's done. Nature does things with molecular perfection.

I was first exposed to the idea of macro-molecular sequences while I was a postdoctoral fellow with Jack Strominger at Harvard. During that time, I briefly visited Fred Sanger's laboratory in Cambridge, England, to learn the methodology of RNA fingerprinting and sequencing.

Manufacturing takes place in very large facilities. If you want to build a computer chip, you need a giant semiconductor fabrication facility. But nature can grow complex molecular machines using nothing more than a plant.

Chemical compounds of carbon can exist in an infinite variety of compositions, forms and sizes. The naturally occurring organic substances are the basis of all life on Earth, and their science at the molecular level defines a fundamental language of that life.

Heat energy of uniform temperature [is] the ultimate fate of all energy. The power of sunlight and coal, electric power, water power, winds and tides do the work of the world, and in the end all unite to hasten the merry molecular dance.

The idea would be in my mind - and I know it sounds strange - is that the most important advances in medicine would be made not by new knowledge in molecular biology, because that's exceeding what we can even use. It'll be made by mathematicians, physicists, computer scientists, figuring out a way to get all that information together.

I am not a climatologist, but I don't think any of the other witnesses are either. I do work in the related field of atomic, molecular and optical physics. I have spent my professional life studying the interactions of visible and infrared radiation with gases - one of the main physical phenomena behind the greenhouse effect. I have published over 200 papers in peer reviewed scientific journals.

I began my thesis research at Harvard by working with a team in the laboratory of William N. Lipscomb, a Nobel chemistry Laureate, in 1976, on the structure of carboxypeptidase A. I did postdoctoral studies with David Blow at the MRC lab of Molecular Biology in Cambridge studying chymotrypsin.

My aging body transmits an ageless life stream. Molecular and atomic replacement change life's composition. Molecules take part in structure and in training, countless trillions of them. After my death, the molecules of my being will return to the earth and sky. They came from the stars. I am of the stars.

I was smart enough to know it would probably make me a salable item for the paparazzi. I knew I'd have to move to a home that had a gate. But that pearl of possibility that lives in your heart when you meet somebody you want to know more about has such a different molecular density than everything else that you have to pursue it.

One can say, looking at the papers in this symposium, that the elucidation of the genetic code is indeed a great achievement. It is, in a sense, the key to molecular biology because it shows how the great polymer languages, the nucleic acid language and the protein language, are linked together.

What have I done? I've blundered my way through life. So I have my picture on the wall. The minute I die, that picture will start to yellow and fade and eventually be gone. Blown in the wind and become part of the molecular structure of something else. These things we see as "success," they're non-accomplishments.

The nucleic acids, as constituents of living organisms, are comparable In importance to proteins. There is evidence that they are Involved In the processes of cell division and growth, that they participate In the transmission of hereditary characters, and that they are important constituents of viruses. An understanding of the molecular structure of the nucleic acids should be of value In the effort to understand the fundamental phenomena of life.

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.

Molecular evidense suggests that our common ancestor with the chimpanzees lived, in Africa, between 5 and 7 million years ago, say half a million generations ago. This is not long by evolutionary standards.

The simplest single-celled organism oscillates to a number of different frequencies, at the atomic, molecular, sub-cellular, and cellular levels. Microscopic movies of these organisms are striking for the ceaseless, rhythmic pulsation that is revealed. In an organism as complex as a human being, the frequencies of oscillation and the interactions between those frequencies are multitudinous.

It is fortunate that molecular synthesis also serves the utilitarian function of producing quantities of rare or novel substances which satisfy human needs, especially with regard to health, and the scientific function of stimulating research and education throughout the whole discipline of chemistry.

Addressing the conclusions of The God Delusion point by point with the devastating insight of a molecular biologist turned theologian, Alister McGrath dismantles the argument that science should lead to atheism, and demonstrates instead that Dawkins has abandoned his much-cherished rationality to embrace an embittered manifesto of dogmatic atheist fundamentalism.
