Each separate biome page contains a brief general description as well as basic information about characteristics such as Temperat
Muscles and Bones
Muscles and Bones offers teachers 10 activities that help students understand how the body's muscles and bones work. The activities in this guide help students explore important questions related to muscles and bones in living things; such as: Do you know which foods have lots of calcium for your bones? What are you doing to keep your muscles strong? and How do your bones and muscles work together?
Nutrition, Inequality and Agriculture: Contested Models of Degenerative Disease in Chiapas, Mexico
The industrial agro-food system has had two significant impacts on world public health: deteriorating human and animal nutrition due to poor food quality and the emergence of new infectious diseases arising from industrial animal production facilities and centralized food processing facilities. This situation is widely misrepresented in media coverage of public health issues. The corporate food system promotes the consumption of high levels of animal protein and processed foods

Dynamic Remodeling of Individual Nucleosomes Across a Eukaryotic Genome in Response to Transcription
The eukaryotic genome is packaged as chromatin with nucleosomes comprising its basic structural unit, but the detailed structure of chromatin and its dynamic remodeling in terms of individual nucleosome positions has not been completely defined experimentally for any genome. We used ultra-high–throughput sequencing to map the remodeling of individual nucleosomes throughout the yeast genome before and after a physiological perturbation that causes genome-wide transcriptional changes. Nearly 80%
Bioterrorism: plague as a biological weapon
Bioterrorism is the utilization of microorganisms or toxins in order to produce a disease and/or death in human beings, animals or plants. Different from conventional weaponry, relatively economic means are used that allow the elimination of living beings without destroying the surrounding atmosphere. The most probably method for spread of bioweapons is aerial transmission, continuing into water supplies and food. The CDC (US Centers for Disease Control and Prevention, Atlanta) has subdivided in
