This is a series of stories about what scientists do at the Agricultural Research Service. It is geared to kids 8 to 13 years old.

In Chiapas, one of the poorest states in Mexico, an estimated 150,000 children are malnourished. To end this problem, governments have implemented food security policies, including food importation and industrial food production. In 2008 alone, Mexico imported 20 million tons of food. While these policies certainly help to remedy the problem in the short term, the massive importation of basic foodstuffs and incentives to industrial agriculture may widen social inequality, threaten health and deteriorate biodiversity and ecosystem services. I will present the objectives and achievements of initiatives born in the highlands of Chiapas to enhance local food production free of hazardous pesticides and appropriate to the culture of the region. Examples include the rescue of local knowledge for food production, a school gardens program and the Network of Producers and Consumers for Healthy Local Food.

Highlights of this course include: Major biological, chemical and physical components of the agricultural systems The scientific basis for understanding these systems and their management How has science influenced policies related to agriculture, food safety and environment in the United States? How have the policies evolved over time in the US? What has worked and what has not; what are the reasons and what are the consequences? Beyond science, what other factors influence policies? How do we link what we learn to ecological agriculture? How do we use what we learn for policy analysis?

In this decision case, a congressional staffer must weigh a number of competing concerns and issues, including popular reactions to genetically modified organisms, in deciding how to present information to her boss, an influential congressman drafting legislation to support agricultural research. The case explores the social and biological issues surrounding micronutrient malnutrition, including deficiencies of several vitamins and essential minerals, especially iron, iodine, and vitamin A, which affect at least one-third of the world's population, primarily in developing nations. Developed for a graduate-level seminar on "Genomics, Agriculture, Food Systems and Development," the case teaches about the issues surrounding genomic applications in agriculture and their implications to health, environmental stewardship, economic sustainability, and national development.

This site provides access to more than 4,000 reviewed resources covering 76 biological science topics: agriculture, anatomy, bacteriology, biochemistry, biodiversity, biotechnology, botany, cardiology, cell biology, ecology, environment, evolution, genetics, geography, human biology, immunology, marine biology, microbiology, molecular biology, neurobiology, pathology, pharmacology, physiology, public health, respiratory biology, soil biology, virology, zoology, and others.

This case focuses on the banana, the most popular fruit in the world. In the first part of the case, students are introduced to the history of "Banana Republics" and the biological constraints to banana production, including the devastating fungal pathogens that cause black Sigatoka and Panama disease. In the second part, they learn about ethical consumerism, organic and conventional agriculture, and Fair Trade products. The case was developed for an interdisciplinary capstone course, "Global Issues in the Sciences." It could also be used in courses in environmental studies, general biology, agriculture, and plant pathology.

This site traces the origins of technological and medical advances. Learn about the genetics of ear wax, a vaccine to control malaria, DNA barcoding, aging and the human brain, a genetic classification of dog breeds, the discovery of the first speech and language gene, how living organisms tune in to the time of day, and more.

Colony Collapse Disorder (CCD) has claimed approximately one-third of the commercial honeybee population in recent years. A number of causes have been suggested for this phenomenon, including the consumption of high fructose corn syrup (HFCS) by the bees. This directed case investigates the issues and chemistry that might be involved in CCD related to HFCS. The case was developed for use in an undergraduate organic chemistry or food chemistry course.

In this case study, students are introduced to concepts and techniques in modern biotechnology, as well as the possible implications of this emerging science, by considering the possibility of in vitro cultured meat. Intended for use in a college-level meat science, food science, or human nutrition course, the case could also be used in courses in environmental science, agribusiness, agriculture law and policy, animal philosophy/well-being, and high school AP food science.
