  • The pebble was tossed into the water by Charles Darwin in 1872 when he declared in his book The Expression of the Emotions in Man and Animals that humans are not the only members of the animal kingdom that experience a wide array of emotions and feelings. Despite the reputation of the renowned biologist, the ripples that this tiny rock generated went largely unappreciated at the time. In fact, these ripples remained quite small until the middle of the next century.

  • Tissue culture was first devised at the beginning of the twentieth century [Harrison, 1907; Carrel, 1912] (Table 1.1) as a method for studying the behavior of animal cells free of systemic variations that might arise in vivo both during normal homeostasis and under the stress of an experiment. As the name implies, the technique was elaborated first with undisaggregated fragments of tissue, and growth was restricted to the migration of cells from the tissue fragment, with occasional mitoses in the outgrowth.

  • Much of the literature concerning health benefits of physical activity is based on studies done primarily with men. Only recently have large-scale studies been initiated to investigate the effects of physical activity on women’s health and wellness. Chris Wells, the author of this paper, has been a pioneer in the study of physical activity for women. As you will see, much more research studying girls and women is necessary, but much has been accomplished in recent years. Diseases often thought to be “diseases of men” affect women as well as men.

  • Early interest in selenium by nutritionists concerned its high concentration in certain range plants and the consequent toxicosis in animals that grazed those plants. More recently, the essential nature of selenium has become the center of attention, and this element is now known to be required by laboratory animals, food animals (including fish), and humans. Its role as an integral feature of glutathione peroxidase has been established, and other possible functions are under active investigation.

  • Congress established a standing disaster program in the 2008 farm bill— the Supplemental Revenue Assistance Payments Program. Under this program, Congress funded a $3.8 billion permanent trust fund and directed the Secretary of Agriculture to make crop disaster assistance payments to eligible farmers who suffer crop losses on or before September 30, 2011. USDA—through FSA—began making disaster payments under this program in early 2010 for crop losses incurred in 2008.

  • Nutrition during childhood and adolescence is essential for growth and development, health and well-being. [1,2] Further, eating behaviors established during childhood track into adulthood and contribute to long-term health and chronic disease risk. [3,4] Numerous studies have consistently documented that dietary intake patterns of American children and adolescents are poor and do not meet national dietary goals. [5-8] In addition, US food consumption trend data show a shift over the past few decades.

  • Currently there is uncertainty about the degree of difference in nutrient composition between conventionally and organically produced foodstuffs. Organic foodstuffs are those that are produced according to specified standards which, among other things, control the use of chemicals and medicines in crop and animal production, and emphasise protection of the environment. Recently published non-systematic reviews comparing nutrient composition of organically and conventionally produced foods have come to contrasting conclusions.

  • Within the overall transport process, attenuation processes may cause movement of the chemical to differ from that of the bulk flowing groundwater, for example dispersion, sorption and chemical or biological degradation of the chemical. Such attenuation processes potentially act to mitigate the impact of chemicals and are a function of both the specific chemical and geologic domain. Indeed, attenuation may vary significantly between individual chemicals and within different geological settings.

  • building raised beds. Raised beds have soil a few inches or more higher than the surrounding area, which provides extra rooting depth, and helps the soil drain and warm up in the spring. They’re typically 3 to 4 feet wide, with mulched paths in between, so you walk on the paths and don’t compact the soil in planting areas. Raised bed sides can be made with reused lumber, broken concrete or concrete blocks, recycled plastic lum- ber, or any non-toxic material. (Don’t use treated wood.) You can also make raised beds without sides. Dig a few inches of soil out of...

  • A mandate requiring all individuals to pur- chase health insurance would be an unprece- dented form of federal action. The government has never required people to buy any good or service as a condition of lawful residence in the United States. An individual mandate would have two features that, in combination, would make it unique. First, it would impose a duty on individuals as members of society. Second, it would require people to purchase a specific service that would be heavily regu- lated by the federal government.
