David R. Montgomery See book keywords and concepts | Major scientific advances fundamental to soil chemistry occurred in the late eighteenth and early nineteenth centuries. Daniel Rutherford and Antoine Lavoisier respectively discovered nitrogen and phosphotus four years before the American Revolution. Humphrey Davy discovered potassium and calcium in 1808. Twenty years later Friederich Wohler synthesized urea from ammonia and cyanuric acid, showing it was possible to manufacture organic compounds.
Humphrey Davy endorsed the popular theory that manure helped sustain harvests because organic matter was the source of soil fertility. | Devra Davis See book keywords and concepts | In fact, the decline of epidemics in the nineteenth century had nothing to do with breathtaking scientific advances; all of these came much later. Deaths from germ-fed contagious diseases began to ebb long before microscopes or drugs could find or kill them. This decline happened because dirty water, crowded housing, rotten food and dangerous jobs became much less common in developed nations. | Benjamin H. Natelson, M.D. See book keywords and concepts | Sad to say, some doctors don't care much about the latest scientific advances, unless they pertain directly to their own very narrow specialty. Others are too busy to keep up with these advances, and others are just cold fish when it comes to caring about patients.
Often, the key to finding the most appropriate and helpful specialist is being able to trust your primary-care provider to steer you toward the right one. I can't emphasize enough how important it is for you to have a primary-care provider with whom you feel comfortable. | Gregg Braden See book keywords and concepts | During the early 1900s, however, scientific advances showed us two places in nature where Newton's laws just don't seem to work: the very large world of galaxies and the very small one of quantum particles. Before that time, we simply didn't have the technology to watch the way atoms behave during the birth of a distant star or to peer into the subatomic universe. In both these large and small realms, scientists began to see things that couldn't be explained by classical physics. | Bill Sardi See book keywords and concepts | Much work remains to be done, Harris said, adding: "The crux of the crisis in oncology is that for years we have developed tremendous scientific advances in looking at how cancer develops, and that's not being translated into practical solutions that are benefiting patients at the pace you would expect. Look at what the government and all the drug companies are spending, and yet drugs are not reaching the market. | Gary Null See book keywords and concepts | | Putting all these factors together—incorporating scientific advances to increase the natural life span, improving the quality of life, and living an optimal lifestyle, will really pack a synergistic punch against aging.
UPDATING "OLD" IDEAS
By looking at the mass media, you wouldn't necessarily notice that a paradigm shift is occurring. On TV, for instance, there are still a lot of stereotyped "oldsters"—crotchety, annoying people who aren't very active and who like to sit around complaining about their ills. | Marion Nestle See book keywords and concepts | CONCLUSION
THE FUTURE OF FOOD SAFETY
PUBLIC HEALTH VERSUS BIOTERRORISM
SAFE FOOD IS ONE OF THE GREAT ACHIEVEMENTS OF TWENTIETHcentury public health, a result of scientific advances in refrigeration, pasteurization, insecticides, and disease surveillance. This book proposes that food safety also depends on politics. Any doubts about that idea should be thoroughly dispelled by the events of September 2001, when terrorists used airplanes as weapons of destruction and an anonymous correspondent sent letters filled with anthrax spores to civic and media leaders. | Peter Pringle See book keywords and concepts | By the end of the nineteenth century, the Japanese were breeding the most efficient food crops in the world; it would be several decades before the West matched their scientific advances. Some of the more famous dwarfs would come from Taiwan, having survived Japanese efforts to extinguish them. An early rice favorite was called shinriki, which in Japanese means "power of the gods."4
At first, Westerners had viewed the Japanese obsession with dwarf plants as a mere curiosity, like their miniature gardens. When Horace Capron, the U.S. | The Life Extension Editorial Staff See book keywords and concepts | Although scientific advances have been made in defining the metabolic mechanisms that occur in our bodies after we ingest calories, medicine has not progressed beyond the you-ate-too-much'so-you-got-fat concept.
The intrinsic difficulty with such simplistic explanations for weight gain is the fact that overeating does not automatically make a person become fat. We all know people with an unfair ability to eat anything and everything without gaining an ounce. There are published studies showing that dieting does not make an obese person thin over the long term (Toubro et al. | Bradley J. Willcox, M.D., D. Craig Willcox, Ph.D., Makoto Suzuki, M.D. See book keywords and concepts | KEY FINDING #4
Biomarkers Show Health Benefits of the Okinawa Diet
One of the most exciting recent scientific advances is the discovery of biological markers of healthy weight and healthy aging.58 Biomarkers are biological or physiological factors in our bodies that can be measured to help predict our risk for certain diseases, how long we will live, and how many of those years will be vital ones (given relatively healthy lifestyles). | The Life Extension Editorial Staff See book keywords and concepts | We call this concept "Scientific Medicine" because it involves the transfer of scientific advances from the laboratory to the front lines of patient care.
SCIENTIFIC PHYSICIANS
Physicians who practice Scientific Medicine react uniquely when they hear about a new therapy. Their curiosity motivates them to evaluate the new therapy for safety and efficacy in the context of treatment regimens appropriate to their patients' conditions. | David Heber, M.D., Ph.D. See book keywords and concepts | The academic community would like to optimize the health value of the diet through scientific advances in our understanding of human biology. Within the constraints of its survival as a profitable venture, the food industry generally operates with good intentions in this regard. Government is caught in the middle, often receiving inconsistent advice from the academic community and having to deal with the food industry's efforts to evade regulations that adversely affect its bottom line. | Richard Gerber, M.D. See book keywords and concepts | To evaluate a drug's effectiveness, doctors will look for precise relations between drug dosage and therapeutic patient responses. scientific advances in pharmacological medicine have all but antiquated the use of once-common natural or herbal remedies.
The Newtonian model of synthetic drug therapy does allow physicians to make reliable predictions of drug behaviors and to eliminate certain side effects of natural remedies—but at what expense? Perhaps there are important energetic healing factors which have been left out in the scientific transformation of herbal medicine to drug therapy. | Donald R. Yance, j r.,C.N., M.H., A.H.G., with Arlene Valentine See book keywords and concepts | Most physicians practicing medicine today make full use of the steadily increasing body of scientific medical knowledge, sophisticated diagnostic procedures, and pharmacology, but many, in their fascination with the latest scientific advances, including diagnostic hardware, blood testing, and the wide array of cytotoxic cancer treatments currently available, have forgotten that some of the most valuable healing experiences—for both patient and healer— come from the human interaction that takes place between the two. | Berkeley Holistic Health Center and Shepherd Bliss See book keywords and concepts | | Since World War II the technical and scientific advances in medicine have far exceeded the social and cultural advances. We physicians need to reassess the total health of our individual patients, and, in turn, that of our entire society. In this all people may benefit from the cultural, the environmental, the mental, the physical, and the religious advances. Further, it seems not unreasonable that physicians must integrate (and engage sooner or later in) the practice patterns that deal with physical, mental, spiritual, and environmental health in some comprehensive manner. | Joseph Glenmullen, M.D. See book keywords and concepts | Reviewing the history of these drugs, one finds a strikingly similar pattern: Initially, the drugs are aggressively marketed with claims that they are revolutionary breakthroughs, remarkable scientific advances over their predecessors. Early on, a few doctors champion their cause, becoming celebrities along with the drugs. Often, a handful of celebrities step forward to endorse the miracle cure. As they gain momentum, use of the drugs spreads beyond the confines of psychiatry and they are prescribed by general practitioners for everyday maladies. | Richard Gerber, M.D. See book keywords and concepts | Recent scientific advances in immunology have discovered that there are subcategories of T-lymphocytes known as T-helper and T-suppressor cells. T-helper cells assist antibody-producing and other types of defender cells in removing foreign or "non-self" proteins and invaders from the body. There are also other special lymphocytes called killer T-cells which are known to destroy cancer cells. These cells participate in the so-called immunosurveillance function of the immune system, which screens, not only for foreign invaders such as bacteria and viruses, but also for cancer cells. | Marion Nestle See book keywords and concepts | Early in the twentieth century, as scientists began to identify the structure and function of one vitamin after another, the USDA immediately translated these scientific advances into advice for consumers. By 1915 or so, the agency had produced at least 30 pamphlets to inform "housekeepers" about the nutritive value of foods, the role of specific foods in the diet, and foods appropriate for young children at home or at school.
Food Groups
In 1917, the USDA issued its first set of overall dietary recommendations as a 14-page pamphlet, titled How to Select Foods. | Carl Jensen See book keywords and concepts | The IFPRI reported that while scientific advances in agriculture have boosted worldwide food production in recent decades, a record explosion in the world's population will outstrip food production in coming years if research on new farming technologies and food policies is neglected (Chicago Tribune, 4/4/94).
One hopeful sign is the formation of the Tufts International Famine Centre at University College, Cork, Ireland, according to Dr. J. Larry Brown, of Tufts University in Boston. He said for the first time, widespread famine and disaster related deaths could be prevented. | Samuel S. Epstein, M.D. See book keywords and concepts | DHHS Secretary Sullivan announced that he would request Congress to repeal the Delaney law on which the ban was based in view of recent scientific advances which have allegedly made this law obsolete. Still more ominously, OMB economists have attempted to enforce on OSHA's scientists new definitions of chemical carcinogens, which would restric-tively exclude from regulation the majority of chemicals found to be carcinogenic in valid animal tests, and which would impose requirements for epidemiological confirmation of animal carcinogenicity data. | Martin L. Cross See book keywords and concepts | In many ways, as we shall see, medicine is moving backward rather than forward even as new scientific advances are made daily.
We shall look beyond the taboos of the profession to closely examine physicians, hospitals, insurers, and medical colleges and their students, after which we will offer reasoned suggestions on how to solve the many problems. In a burst of optimism, we will try to redesign much of the conventional system of medical care in America at the turn of the new century. | Francisco, M.D. Contreras See book keywords and concepts | | Our professors were of the opinion that infectology would be an extinct specialty because scientific advances in pharmacology were so promising that surely there would soon be antibiotics to eradicate every kind of infection. I felt proud and at the same time unworthy to be part of a group of scientists that could have such an impact on the future of humanity. While my comrades deliberated the specialty they would enter, I was set on surgery. I had made that decision many years earlier when I accepted that my future as a pianist was limited. | | Field of Medicine
The second half of this century has seen the greatest technological explosion in the history of medicine - chemical syntheses of pharmaceuticals, genetic engineering, computerization in microbiology, nuclear medicine, gamma knife, transplants, endoscopic surgery, surgical training simulators, and hundreds of other scientific advances. In the clinical field, new devices facilitate the work of physicians. Computer programs exist which diagnose and recommend a treatment. It is now possible to examine organs using a tiny probe that functions as a video camera. | | Before the advent of these scientific advances, the authorities used desperate methods to try and control epidemics. They buried corpses together with all their belongings and burned them; in some cases even entire cities. They petitioned the heavens and offered all sorts of sacrifices. Some placed the blame on Jews and in desperation and hatred, massacred 600 in Brussels and 2000 in Strasbourg.
Up to this time, scientists could do nothing but just stand as spectators of the plague's hurricanes. | | In fact, the downward slope in the graph indicates that improvement began a long time before modern scientific advances, like radiation therapy, were introduced. The improvement is due to a simple invention in 1928 by Dr. Papanicolau, who created the test which detects cervical cancer - the "PAP SMEAR." As hard as it may be to believe, the FDA wouldn't approve this test until 1940. Imagine how many women died needlessly because of this terminal delay. Yet, no one claimed responsibility for this negligence. | | In all the other malignancies graphed, statistical records indicate that the "enormous scientific advances" have not helped patients survive. On the contrary, where the malignancies are treated with aggressive remedies, the death rates are incredibly high. Even if the patients survive, the quality of life they endure afterwards is impaired, often permanently. The death rate of people suffering from pulmonary cancer has literally exploded. This is due to the fact that many women began smoking cigarettes in the 1960's as a result of the women's liberation movement. | Alexander Hellemans and Brian Bunch See book keywords and concepts | Its progress was not only determined by the great discoveries of a talented few, such as Einstein, Bohr, and Rutherford, but also by the numerous small steps made by specialized researchers who did not have a famous formula or law named after them. Many scientific advances were also made by teams of researchers, each working on a small piece of the puzzle. |
