genetic aspects

Describes how scientists are conducting the search for genes that influence susceptibility to manic-depressive illness by taking DNA samples from relatives who suffer from the disorder, and discusses the implications of their findings for other mental illnesses such as autism, Tourette's syndrome, and schizophrenia.

A scientific tour of the aging of the human body, investigating the complexities of tissues, cells, and genes, looking at how historically familiar people have experienced aging and death, and discussing discoveries that may lead to longer lives.

Describes the hunt for genes that tragically predispose some rare families to Alzheimer's disease.

Explores evolutionary history for answers to why certain diseases exist, discussing the effects of environmental factors such as climate, food, and drink on the genes of human ancestors thousands and hundreds of years ago, and examines connections between genetic inheritance and who gets which diseases.

Examines how mental illness research has progressed to its current state as well as the prime focuses of scientific research, including the search for genetic links and the development of treatments.

Provides a brief overview on the history of Nutrition and the future of nutrigenomics. Discusses the recent controversies and issues relating to nutrition so Americans can make an informed choice about the foods they eat.

Explores key topics in genetics and evolution, focusing on recent discoveries, especially in the area of reproductive technology, and looks at the ongoing debates about the ethics of genetic engineering.

Examines the history of modern genetic cancer research and treatment, which began with scientist David Hungerford in Philadelphia, 1959. Hungerford discovered a missing piece of human DNA; today that missing piece has been linked with chronic myeloid leukemia, and research on it has led to several instances where cancer has been treated at the genetic level.

A collection of articles debating issues related to genetics and intelligence, such as whether genetics influences intelligence, the validity of IQ tests, IQ differences among races, and the role IQ research should play in determining social policies.
