We are close to dead. There are faces and bodies like gorged maggots on the dance floor, on the highway, in the city, in the stadium; they are a host of chemical machines who swallow the product of chemical factories, aspirin, preservatives, stimulant, relaxant, and breathe out their chemical wastes into a polluted air. The sense of a long last night over civilization is back again.
Dissection... teaches us that the body of man is made up of certain kinds of material, so differing from each other in optical and other physical characters and so built up together as to give the body certain structural features. Chemical examination further teaches us that these kinds of material are composed of various chemical substances, a large number of which have this characteristic that they possess a considerable amount of potential energy capable of being set free, rendered actual, by oxidation or some other chemical change. Thus the body as a whole may, from a chemical point of view, be considered as a mass of various chemical substances, representing altogether a considerable capital of potential energy.
It's chemical, fancying him is purely chemical. It's intoxicating - the frisson, the attraction - it's intoxicating because it's purely chemical. But you'll just have to remember the wedding ring - divorcees don't wear wedding rings. This guy has his own Vita at home. You're his potential Suzie. Is that who you want to be? Do you want the next man in your life to have Tim's principles?
And, as a consequence of the pressure that we've applied over the last couple of weeks, we have Syria -- for the first time -- acknowledging that it has chemical weapons, agreeing to join the convention that prohibits the use of chemical weapons, and the Russians -- their primary sponsors -- saying that they will push Syria to get all of their chemical weapons out. The distance that we've traveled over these couple of weeks is remarkable.
I have spent years... clinging to the understanding that I was a defective biological unit... This may truly be a valuable perspective for those who observe mental illness, but for me, as a subject, this tree bore only dry and tasteless fruit... I have a chemical imbalance; I really didn't feel those things. I have a chemical imbalance; I didn't really experience those things. I have a chemical imbalance; I didn't really think those things... Here is an insight! The entire human drama of love, suffering, ecstasy, and joy, just chemistry.
The digestive canal is in its task a complete chemical factory. The raw material passes through a long series of institutions in which it is subjected to certain mechanical and, mainly, chemical processing, and then, through innumerable side-streets, it is brought into the depot of the body. Aside from this basic series of institutions, along which the raw material moves, there is a series of lateral chemical manufactories, which prepare certain reagents for the appropriate processing of the raw material.
Although the problem of transmuting chemical elements into each other is much older than a satisfactory definition of the very concept of chemical element, it is well known that the first and most important step towards its solution was made only nineteen years ago by the late Lord Rutherford, who started the method of the nuclear bombardments.
You don't seem mad at all, ' she said. But I am, although I'm undergoing a cure, because my problem is that I lack a particular chemical. However, while I hope that the chemical gets rid of my chronic depression, I want to continue being mad, living life the way I dream it, and not the way other people want it to be. Do you know what exists out there, beyond the walls of Villete?
An example of such emergent phenomena is the origin of life from non-living chemical compounds in the oldest, lifeless oceans of the earth. Here, aided by the radiation energy received from the sun, countless chemical materials were synthesized and accumulated in such a way that they constituted, as it were, a primeval 'soup.' In this primeval soup, by infinite variations of lifeless growth and decay of substances during some billions of years, the way of life was ultimately reached, with its metabolism characterized by selective assimilation and dissimilation as end stations of a sluiced and canalized flow of free chemical energy.

At another location, we found barrels of chemical material that was intended for use as biochemical weapons. Everyone talks about there being no weapons of mass destruction in Iraq, but they seem to be referring to completed nuclear bombs, not the many deadly chemical weapons or precursors that Saddam had stockpiled.
I'm a member of the American Chemical Society, and in its magazine, the 'Chemical and Engineering News,' there was an interview of Vince Gilligan when he had first started the television show 'Breaking Bad.' And in that interview, he was stating how important it was to him that he get the science right for the show.
Liebig was not a teacher in the ordinary sense of the word. Scientifically productive himself in an unusual degree, and rich in chemical ideas, he imparted the latter to his advanced pupils, to be put by them to experimental proof; he thus brought his pupils gradually to think for themselves, besides showing and explaining to them the methods by which chemical problems might be solved experimentally.
The last UN weapons inspectors left Iraq in October of 1998. We are confident that Saddam Hussein retains some stockpiles of chemical and biological weapons, and that he has since embarked on a crash course to build up his chemical and biological warfare capabilities. Intelligence reports indicate that he is seeking nuclear weapons...
The Soviet Union has long been proposing to outlaw chemical weapons, to remove them from the arsenals of states. We are prepared for resolution of this problem either on a global basis or piece by piece. As one of the first steps the USSR and the other socialist countries proposed in January 1984 that agreement be reached on ridding Europe of all types of chemical weapons.
When one studies strongly radioactive substances special precautions must be taken if one wishes to be able to take delicate measurements. The various objects used in a chemical laboratory and those used in a chemical laboratory, and those which serve for experiments in physics, become radioactive in a short time and act upon photographic plates through black paper. Dust, the air of the room, and one's clothes all become radioactive.
The mechanist is intimately convinced that a precise knowledge of the chemical constitution, structure, and properties of the various organelles of a cell will solve biological problems. This will come in a few centuries. For the time being, the biologist has to face such concepts as orienting forces or morphogenetic fields. Owing to the scarcity of chemical data and to the complexity of life, and despite the progresses of biochemistry, the biologist is still threatened with vertigo.
Andre Michel Lwoff
You have heard of the new chemical nomenclature endeavored to be introduced by Lavoisier, Fourcroy, &c. Other chemists of this country, of equal note, reject it, and prove in my opinion that it is premature, insufficient and false. These latter are joined by the British chemists; and upon the whole, I think the new nomenclature will be rejected, after doing more harm than good. There are some good publications in it, which must be translated into the ordinary chemical language before they will be useful.
[G]enes make enzymes, and enzymes control the rates of chemical processes. Genes do not make "novelty seeking" or any other complex and overt behavior. Predisposition via a long chain of complex chemical reactions, mediated through a more complex series of life's circumstances, does not equal identification or even causation.
Stephen Jay Gould
As crude a weapon as the cave man's club, the chemical barrage has been hurled against the fabric of life - a fabric on the one hand delicate and destructible, on the other miraculously tough and resilient, and capable of striking back in unexpected ways. These extraordinary capacities of life have been ignored by the practitioners of chemical control who have brought to their task no "high-minded orientation," no humility before the vast forces with which they tamper.
The nerve agent VX is one of the most toxic ever developed. 13,000 chemical bombs were dropped by the Iraqi Air Force between 1983 and 1988, while Iraq has declared that 19,500 bombs were consumed during this period. Thus, there is a discrepancy of 6,500 bombs. The amount of chemical agent in these bombs would be in the order of about 1,000 tonnes.
We are now witnessing, after the slow fermentation of fifty years, a concentration of technical power aimed at the essential determinants of heredity, development and disease. This concentration is made possible by the common function of nucleic acids as the molecular midwife of all reproductive particles. Indeed it is the nucleic acids which, in spite of their chemical obscurity, are giving to biology a unity which has so far been lacking, a chemical unity.
C. D. Darlington
Every living thing is an elaboration of a single original plan. As humans we are mere increments - each of us a musty archive of adjustments, adaptations, modifications and providential tinkerings stretching back to 3,8 billion years. Remarkably we are even quite closely related to fruit and vegetables. About half the chemical functions that take place in a banana are fundamentally the same as the chemical functions that place in you. It cannot be said too often: all life is one. That is, and I suspect will ever prove to be, the most profound true statement there is.
The chemical compounds are comparable to a system of planets in that the atoms are held together by chemical affinity. They may be more or less numerous, simple or complex in composition, and in the constitution of the materials, they play the same role as Mars and Venus do in our planetary system, or the compound members such as our earth with its moon, or Jupiter with its satellites... If in such a system a particle is replaced by one of different character, the equilibrium can persist, and then the new compound will exhibit properties similar to those shown by the original substance.
Art alone makes life possible "" this is how radically I should like to formulate it. I would say that without art man is inconceivable in physiological terms... I would say man does not consist only of chemical processes, but also of metaphysical occurrences. The provocateur of the chemical processes is located outside the world. Man is only truly alive when he realizes he is a creative, artistic being... Even the act of peeling a potato can be a work of art if it is a conscious act.
How would you describe the difference between modern war and modern industry-between say, bombing and strip mining, or between chemical warfare and chemical manufacturing? The difference seems to be only that in war the victimization of humans is directly intentional and in industry it is "accepted" as a "trade-off." Were the catastrophes of Love Canal, Bhopal, Chernobyl, and the Exxon Valdez episodes of war or of peace? They were in fact, peacetime acts of aggression, intentional to the extent that the risks were known and ignored.
In the four years since the inspectors left, intelligence reports show that Saddam Hussein has worked to rebuild his chemical and biological weapon stock, his missile delivery capability, and his nuclear program. He has also given aid, comfort, and sanctuary to terrorists, including al Qaeda members. It is clear, however, that if left unchecked Saddam Hussein will continue to increase his capacity to wage biological and chemical warfare, and will keep trying to develop nuclear weapons.
There is no sharp boundary line separating the reactions of the immune bodies from chemical processes between crystalloids, just as in nature there exists every stage between crystalloid and colloid. The nearer the colloid particle approximates to the normal electrolyte, the nearer its compounds must obviously come to conforming to the law of simple stoichiometric proportions, and the compounds themselves to simple chemical compounds. At this point, it should be recalled that Arrhenius has shown that the quantitative relationship between toxin and antitoxin is very similar to that between acid and base.
Nature has put itself the problem how to catch in flight light streaming to the earth and to store the most elusive of all powers in rigid form. To achieve this aim, it has covered the crust of earth with organisms which in their life processes absorb the light of the sun and use this power to produce a continuously accumulating chemical difference. ... The plants take in one form of power, light; and produce another power, chemical difference.
Depression, we are told over and over again, is a brain disease, a chemical imbalance that can be adjusted by antidepressant medication. In an informational brochure issued to inform the public about depression, the US National Institute for Mental Health tells people that 'depressive illnesses are disorders of the brain' and adds that 'important neurotransmitters - chemicals that brain cells use to communicate - appear to be out of balance'. This view is so widespread that it was even proffered by the editors of PLoS [Public Library of Science] Medicine in their summary that accompanied our article. 'Depression, ' they wrote, 'is a serious medical illness caused by imbalances in the brain chemicals that regulate mood', and they went on to say that antidepressants are supposed to work by correcting these imbalances. The editors wrote their comment on chemical imbalances as if it were an established fact, and this is also how it is presented by drug companies. Actually, it is not. Instead, even its proponents have to admit that it is a controversial hypothesis that has not yet been proven. Not only is the chemical-imbalance hypothesis unproven, but I will argue that it is about as close as a theory gets in science to being dis-proven by the evidence.
In the vestibule of the Manchester Town Hall are placed two life-sized marble statues facing each other. One of these is that of John Dalton... the other that of James Prescott Joule... Thus the honour is done to Manchester's two greatest sons-to Dalton, the founder of modern Chemistry and of the atomic theory, and the laws of chemical-combining proportions; to Joule, the founder of modern physics and the discoverer of the Law of Conservation of Energy. One gave to the world the final proof... that in every kind of chemical change no loss of matter occurs; the other proved that in all the varied modes of physical change, no loss of energy takes place.

My laboratory is interested in the related challenges of understanding the origin of life on the early earth, and constructing synthetic cellular life in the laboratory. Focusing on artificial life frees us to explore novel chemical systems, but what we learn from these systems helps us to understand possible pathways leading to the origin of life. Our basic design for a synthetic cell involves the encapsulation of a spontaneously replicating nucleic acid, which acts as the genetic material, within a spontaneously replicating membrane vesicle, which provides spatial localization. We are using chemical synthesis to make nucleic acids with modified nucleobases and sugar-phosphate backbones.
