The farmers, workers, and pioneers of America in the 1800s were nourished by a tradition of hearty, down home cooking that is still a part of our national cuisine - New England baked beans, roast beef, turkey, corn on the cob, and pumpkin pies. With roots in the British Isles, and with important contributions from Native American food plants and cooking techniques, American food and drink quality and seasonal variety was vastly improved during the 1800s by new technologies in transportation, food storage, hygiene, and preservation, growing national and world markets, and not least the delicious ethnic cuisines of new immigrant groups. Hungry for innovation, quality, and economy, Americans in the 1800s became the best fed nation in the history of the world!
Medicine developed into a science in the 1800s, but it was a long evolution from folk remedies and superstition to a modern understanding of how the human body works and how disease is spread. Throughout much of the century, the life expectancy of the average American was decades shorter than it is now. A lack of understanding of simple hygiene contributed to the early death of many women after childbirth, and children routinely died of common childhood diseases like measles. An incorrectly treated broken arm could kill a healthy young man, and pain, disfigurement, and epidemic disease was the fate of many Americans. Traditional herbal remedies were sometimes the best treatments available, while patent medicines often contained toxic substances, and medical procedures were often painful, disgusting, and ultimately useless. The dedicated scientists and medical researchers of the 1800s made a tremendous contribution to the health and happiness of Americans.

Television programs and feature films present criminal psychology and profiling as a blend of psychic visions, supernatural intuition, and evidence analysis. The reality, however, is quite different.

A flake of skin, a strand of hair, a fleck of saliva, a drop of blood - everywhere we go we leave behind bits of ourselves that are as unique as fingerprints. Each cell contains genetic material called DNA, which holds information that scientists can use to learn about the person who left those cells behind. In the past twenty-five years, researchers have made significant advances in all disciplines of science, including the study of genetics. As science has leapt forward, the effect on forensics has been remarkable. New knowledge of DNA has dramatically changed the amount of information available to forensic scientists at the scene of a crime, opening doors that were never open before.
The famous Lindbergh kidnapping in the 1930s was solved, in part, through a detailed analysis of the kidnapper's handwriting.

Who committed the crime? When? Even the smallest of witnesses can tell scientists stories that will make or break a criminal case. Insects and pollen grains help forensic scientists bring criminals to justice. A suspect escapes a crime scene, leaving not a trace of evidence behind - except for the hind leg of a grasshopper, which helps convict him of murder. A thief runs through a cornfield, relieved that no one saw him commit the crime - unaware of the tiny grains of pollen stuck to his shirt. Plants and insects hold clues to guilt or innocence. Evidence from nature is all around us, silently and swiftly leaving fingerprints, unnoticed by even the most cunning of criminals.
Welcome to the exciting world of forensic investigation, the science of solving crimes. This introduces the field of forensic anthropology, where scientists and criminal investigators use the human skeleton to solve some of the worlds most mysterious and violent crimes. From the nineteenth century murderer who boiled his wife in a vat of acid, to the modern day pig farmer accused of murdering more than sixty women, forensic anthropology shows how even the tiniest fragments of bones can reveal the identities of victims as well as killers. From mass-transit accidents to war to genocide and terrorist attacks, this science also pieces together the most scattered and seemingly unidentifiable remains. Using recent finds such as bags of bones in the woods, or the five-thousand-year-old skeleton of a victim of foul play, forensic detectives use the smallest clues, revealing a massive crime-recording device: the human body. See how the dead do tell tales to those who know how to listen!
Why are programs such as CSI, Law & Order, and Cold Case so popular? Our culture is fascinated with crime, and these television shows reveal investigators’ procedures and secrets.
