Teens Connect With... Mutant Bacteria?!  Innovative STEM Lab Gets Hands-on With Evolution

Associate professor of microbiology and genetics Vaughn Cooper has been working with graduate student Taylor Warren ’13 to develop a simple, hands-on method of teaching teenagers about the complexities of evolution. The curriculum, called “Evolution in Action,” takes the abstract concept and turns it into a hands-on activity involving colonies of harmless bacteria that reproduce and mutate at astonishing speeds, allowing students to watch evolution unfold before their eyes over the span of a few weeks. Working with Cooper and Winnacunnet science teachers Mike Handwork ’98 and Shani Scarponi, Warren is assessing the effectiveness of the curriculum as part of her thesis. The long term goal is to create kits that will allow high school students around the country to engage in similar experiments.

From Mill Town to Metropolis, the People and Places of Manchester

Robert Macieski, associate professor of history and director of museum studies at UNH Manchester, is creating a web site that will tell the story of how Manchester grew from mill town to metropolis. With the help of Geographic Information System (GIS) mapping software, census data going back to 1790, city directories, historic maps, and multi-media resources, People and Places will provide a unique tool for exploring the history and geography of the Queen City.

Antarctic Ice Sheet Is Result of CO2 Decrease, Not Continental Breakup

In a paper published in Nature, Matthew Huber of the UNH Institute for the Study of Earth, Oceans, and Space and department of Earth sciences provides evidence that the most likely explanation for the initiation of Antarctic glaciation during a major climate shift 34 million years ago was decreased carbon dioxide (CO2) levels. The finding counters a 40-year-old theory suggesting that massive rearrangements of Earth's continents caused global cooling and the abrupt formation of the Antarctic ice sheet.
