In this commentary, Suess opines that comparing risk- and non-risk-groups, as is done in the study by Witting, Ruiz, and Ahnert (2016), is a favored approach in developmental psychopathology in order to learn more about underlying mechanisms of normal development, as well as developmental deviations. Witting and colleagues followed up this…

T. F. Denson, M. Spanovic, and N. Miller (2009) meta-analytically tested the hypotheses that specific appraisals and emotions would predict cortisol and immune responses to laboratory stressors and emotion inductions. Although the cortisol data supported the integrated specificity hypothesis, G. E. Miller (2009) raised questions concerning the…

Lipidomics is an emerging discipline in life sciences related to the lipid metabolism of living organisms. In the last decade chemical and biological research has attributed very important roles to membrane phospholipids in relationship to free radical stress and metabolic situations. An entrepreneurial initiative for diagnostic tools and health…

The controversy over the safety of saccharin is not resolved, but the discovery of other sugar substitutes may make the problem moot. (JD)

An argument is made in favor of imperfect or unfinished evolution based on some metabolic pathways in which it seems that intelligent design would have done better. The case studies noted indicate the absence of highly intelligent design and are not intended as comprehensive collection but as a limited sample of inefficient situations in…

William Harvey's discovery of the presence of capillaries and the role played by them without actually seeing them highlights his power of observation and logic. However, his perspective could not be considered as new since he had adopted his disposition for ocular demonstration from Aristotle and Galen.

Do you belong to a sports club or gym? Do you like to work out, play tennis, swim, or run regularly? If so, you are also improving your hearing health. I did not learn this from a sports column; I learned it from interviewing Ray Hull. Dr. Raymond H. Hull, PhD, is a professor of communication sciences and disorders, audiology, and director of the…

New information reveals that dinosaurs have a pelvic structure similar to that of animals that walk upright. Science teachers should remember that theories and assumptions are always provisional and tentative. (JN)

Participating in some form of a warm-up prior to engaging in physical activity is considered an acceptable and valid practice. Nonetheless, the topic has been debated among those in the sport and physical education field for a number of years. Some professionals believe warm-up is essential to physical activity, while others believe warm-up is not…

To illustrate the possible relationships between metabolic disorders and autism, this commentary reviews findings from studies on the characteristics of individuals with Rett syndrome that indicate the genetic mechanism of transcriptional dysregulation can produce pathologic phenotypes which resemble metabolic disorders that stunt axonodendritic…

Ideas and scientific definitions as reported by 9-12 year olds collected from class discussions, essays, or examination papers over the course of 32 years are presented. Topics include the living body, tracts, metabolism, the senses, the skeleton, the heart, respiratory ailments, genetics, microbiology, and modern medicine. (KR)

Good nutrition for athletes demands plenty of water, since water is essential to such vital functions as muscle reactions. Dehydration can result from jet travel as well as from exercise and heat, making it a danger to traveling athletic teams. To avoid dehydration, water needs should be monitored by frequent weighing, and a clean water supply…

The author suggests the use of chronobiology--the body's 24-hour cycle rhythms--to chart children's physical, emotional, and mental reactions in order to more realistically and productively structure learning activities. This exercise also involves math and science skills. (KC)
