Glowing Plants on Kickstarter - National Center for Case Study Teaching in Science - 0 views

  •  
    This case study is centered on a real scenario from 2013 in which the Kickstarter fundraising platform included a fundraising proposal from a group wanting to use synthetic biology to make glowing plants. The proposal raised controversy because the Glowing Plant group offered to give away their genetically-modified glowing plant product to investors.  Kickstarter subsequently changed its policy to prevent use of genetically modified organisms as rewards or incentives to investors. This case study was developed for a college first-year seminar focused on the ethics of synthetic biology, and was introduced during the first week of the semester. The case uses the jigsaw teaching method to introduce students both to the mechanics of synthetic biology and to questions about how we should distribute the benefits and burdens associated with new or emerging technologies. It could be adapted for courses in introductory college biology, genetics or bioethics.

Disease Along the River: A Case Study and Cholera Outbreak Game - National Center for C... - 0 views

  •  
    This case study centers on an active teaching game that simulates a cholera outbreak among five villages along a river, similar to the Haitian outbreak of 2010. By enacting the behaviors of fictional villagers, students learn how trade, travel, sanitation practices and geographic location contribute to the spread of diarrheal disease. Documenting various contamination events of village water supplies allows students to trace the progression of the disease and illustrates how adequate sanitation facilities provide protection against the bacteria Vibrio cholera. Originally designed for an undergraduate upper-division biology course focusing on the epidemiology of diseases, the simulation is also appropriate for microbiology and public health courses, as well as lower division undergraduate biology courses and high school. Biology or epidemiology components of the case study can be highlighted depending on the emphasis of the course being taught. The game can be completed within a 45- to 60-minute class period. Playing cards are available from the Supplemental Materials tab; detailed instructions are found in the teaching notes.

    SciGuides are a collection of thematically aligned lesson plans, simulations, and web-based resources for teachers to use with their students centered on standards-aligned science concepts. Human modifications to communities of living organisms in an ecosystem can change the function and processes of that system. The flow of energy through an ecosystem depends upon the diversity of organisms within it; therefore, when this flow is altered, substantial biological and geological changes occur. It is important that our students not only realize that when a local ecosystem is destroyed or negatively affected by human transformations (building, agriculture, technology); the effect is eventually felt globally. We cannot ignore the fact that everything we do impacts our natural environment. The main question is, "How can we be better "keepers of the Earth"?

Center for Food Safety | News Room | AquaBounty Fined for Repeated Environmental Violat... - 0 views

  •  
    Officials in Panama have ruled that AquaBounty Technologies' has been operating in violation of environmental regulations as it experiments with genetically engineered (GE) salmon in that country. In a decision that could challenge the U.S. Food and Drug Administration's (FDA) ongoing safety assessment of AquaBounty's GE salmon, Panamanian officials fined the company $9500. Food & Water Watch, Center for Food Safety and Friends of the Earth called on the FDA today to terminate its regulatory review and deny AquaBounty's pending regulatory application to sell the company's GE fish in the United States.

The Path of a Pathogen - National Center for Case Study Teaching in Science - 0 views

  •  
    Scientists and healthcare professionals initially exhibited little concern over the Zika virus even after evidence of human infection was first identified in 1952; Zika appeared to be both rare and unassociated with morbidity or mortality. Around 2015 all of this changed as journalists, scientists, public health officials, and laypeople scrambled to learn about its varied modes of transmission and devastating consequences (e.g., birth defects and autoimmune disorders). Although research continues to rapidly evolve, this case study directs students to reliable scientific sources (e.g., Centers for Disease Control and World Health Organization) that will likely continue to provide the most current information in order to explore questions such as: Where did the virus come from? How does it spread? What can we do to prevent it? Students will also consider the public health challenges and possible solutions associated with emerging infectious diseases. The case was originally written for an upper-level biology or public health course in which students already have some basic background knowledge regarding viruses, vaccines, and infectious disease.

Keeping to the Straight and Narrow - National Center for Case Study Teaching in Science - 0 views

  •  
    This case study tells the story of a group of ten men, recently released from federal penitentiaries, who are housed in a residential reentry center for the remainder of their sentences. Their stay is intended to bridge the gap between incarceration and return to life in the community. Due to the length of time served, the men are poorly skilled in healthy behaviors and self-reliance in the areas of food and activity. Although a work of fiction, the narrative realistically portrays a variety of challenges that the men face including a chronic health issue, menu planning, tight budgets, hunger, boredom, lack of cooking skills, and life without a local supermarket. Innovation, trial and error, and collaboration result in a story of resilience and health behavior change in a sparsely populated area of Northern Michigan. The case was originally developed for a college-level nutrition course, but could also be used in social work, community health, and health education, nursing, and dietetics classes.

Becoming a Friend Instead of a Foe - National Center for Case Study Teaching in Science... - 0 views

  •  
    This case study centers on symbiotic relationships between insects and bacteria using Drosophila melanogaster, the common fruit fly, and the recently discovered bacterial species Sodalis praecaptivus. Until recently, the only known Sodalis species of bacteria were symbiotically associated with several different species of insects. However, free-living non-symbiont Sodalis species are being tested in several different insect species to determine if they can transition into symbiotic relationships. A pre-class assignment (see Supplemental Materials) directs students to read an open access research journal article providing a comprehensive review of S. praecaptivus and describing an experimental weevil model that parallels that of the fruit fly. A PowerPoint presentation shown in class (see Supplemental Materials) provides further background before students work in small groups to complete the case study focusing on results from D. melanogaster and S. praecaptivus model experiments.  Although developed for a genetics course, this interrupted case is appropriate for an upper-level biology course. It can be completed within a 75-minute class meeting, or adapted for shorter time periods.

Relevant pathogens from A-Z - 0 views

  •  
    Which pathogens play a major role in causing infection? Just recently, the Robert Koch-Institute prepared a list of 127 pathogens by ranking them in terms of frequency, spread and burden of disease.   Considering this prioritisation, we extended our search tool by bacteria, viruses and fungi accordingly. In the list, you will find both the clinically relevant pathogens and the spectrum of effect necessary for disinfectants to inactivate them.

World population growth is expected to nearly stop by 2100 | Pew Research Center - 0 views

  •  
    For the first time in modern history, the world's population is expected to virtually stop growing by the end of this century, due in large part to falling global fertility rates, according to a Pew Research Center analysis of new data from the United Nations. By 2100, the world's population is projected to reach approximately 10.9 billion, with annual growth of less than 0.1% - a steep decline from the current rate. Between 1950 and today, the world's population grew between 1% and 2% each year, with the number of people rising from 2.5 billion to more than 7.7 billion.
