Butterflies in the Stomach - National Center for Case Study Teaching in Science - 0 views

  •  
    Why is the North American population of monarch butterflies declining? In 1999, a study published in the journal Nature suggested that a variety of genetically modified corn was killing these iconic butterflies. While it was later shown that the conditions in this study did not mirror those in the field, the results garnered a lot of media attention and many people today still believe that monarchs are being killed by GMOs. This case familiarizes students with the plight of the monarchs, encourages them to think about how to test the hypothesis that a toxin is responsible for their decline, and takes a critical look at several studies that investigated the role of Bt corn in the life cycle of monarchs. This interrupted case takes 60-90 min to complete, requires little to no science background, and can be used to explore the ecology and wildlife management of monarchs; risk assessment, toxicity, and exposure; experimental design, the scientific method, hypothesis, and critical thinking; or the relationship between science, the media and the public.

Vaccines, Social Media, and the Public Health - National Center for Case Study Teaching... - 0 views

  •  
    While the "vaccine controversy" has made headlines since the late 1990s, the emergence and popularity of social media has created a public opinion space bursting with pseudoscience, debatable claims and anecdotes regarding the value and importance of childhood vaccines. Because college students get a good deal of news and information from these resources, it is imperative that they distinguish science from pseudoscience and do not perpetuate rumor and falsehoods.  In this case study, written for lower division non-science majors, students will view videos on the scientific method and a mock talk show, analyze data, and scrutinize social media posts.  One of the takeaway points is that if a post/blog/interview identifies a victim, villain, and hero then the student should suspect a story grounded in belief involving pseudoscience.  Following completion of the case, students will hopefully come to conclusions about vaccines based more in the realm of science rather than pseudoscience and continue to apply the scientific method when evaluating social media posts on other scientific topics.

    Reporting on a small preliminary study, Johns Hopkins researchers say a simple blood test based on detection of tiny epigenetic alterations may reveal the earliest signs of pancreatic cancer, a disease that is nearly always fatal because it isn't usually discovered until it has spread to other parts of the body.

Snakebites deadly as other diseases in West Africa | Science/AAAS | News - 0 views

  •  
    West Africa was under the media spotlight this year-and rightly so after nearly 11,000 people died in the largest Ebola outbreak ever recorded. But although the disease flickers in and out of the public consciousness, a new study shows that another killer was nearly as deadly: snakebites.
