  • Bretwood "Hig" Higman '99: Broadband, Yes. Toilet, No.

    December 30, 2009

    ON a trip to the Yucatán Peninsula in Mexico during spring break, Bretwood Higman '99 and Erin McKittrick '01 found themselves on a beach, holding a battered tourist map. Sick of the collegiate shenanigans around them, Mr. Higman suggested they ditch the bars, take the map and walk the 30 miles of shoreline to the next town. “The beach is probably continuous, right?” Ms. McKittrick remembers him saying.

    To his surprise, Ms. McKittrick, whom he had met while they were studying at Carleton College outside of Minneapolis, was game. “That was a defining moment,” said Mr. Higman, now 33; he knew Ms. McKittrick was the one.

    Ten years later, they are married, have an 11-month-old son and have walked more than 7,000 miles together. “When we got together, it was more than the sum of the parts,” said Ms. McKittrick, 30. “Much more.”

  • Holly Ewing '89 Leads Students In Lake Water Biochemistry Study

    December 15, 2009

    "Many lakes in Maine are clear and have relatively small amounts of nutrients coming in from outside," says Holly Ewing, assistant professor of environmental studies at Bates College.

    "Those of us who like to live on clear lakes, take drinking water from them and use them for recreation want to see them remain clear," Ewing says. But a process called lake eutrophication is spoiling clearwater lakes in Maine and elsewhere as higher levels of nutrients encourage blooms of algae and bacteria, many of which form scums or mats on lakes.

    When these organisms die and decompose, their decomposition can use up the oxygen in the water — bad news for fish and other organisms that need oxygen.

  • Prof. Mary Savina '72 And Suzanne Savanick Hansen '89 Help Win Funding To Study Adding Sustainability To Undergraduate Curriculum

    December 8, 2009

    Professor Mary Savina '72 and another alum, Suzanne Savanick Hansen '89, were among those who recently received Faculty Career Enhancement (FaCE) grants from the Associated Colleges of the Midwest (ACM) to support collaborative faculty workshops with their proposal entitled "Integrating Sustainability into the Undergraduate Curriculum."

    The goal of this cross-disciplinary and cross-college collaboration is to develop, assess, and then disseminate well thought-out pedagogical strategies and practical, meaningful, usable activities for introductory courses across the disciplines at our institutions and beyond. Teaching and learning resources that will be developed over the course of the project will be disseminated online.

  • Naomi Lubick '94 Is Writing For Scientific American And NATURE

    November 20, 2009

    Carcasses of adult crocodiles do not usually signal the return of winter in South Africa, but mass death seems to be becoming the harbinger of the season. Rangers at the Kruger National Park have found Nile crocodiles floating in the Oli­fants River or bloated and decaying along its banks. Investigators are rushing to figure out the cause and worry that the deaths might be signaling the presence of toxins or pathogens that could threaten not only the croc population but also the livelihoods of the people living near the river.

    The Olifants River runs several hundred kilometers through three South African provinces and into Mozambique. It supplies water to industrial agriculture operations that send food to Europe and to the local rural communities, which also depend on those waters for fishing and farming.

    Thus begins one of Naomi's recent articles in Scientific American.

  • Alton Dooley '91 Discusses The National Decline In Geology Enrollments

    November 20, 2009

    There have been a number of disturbing reports recently about the reduction or elimination of various geoscience organizations, including the University of Wyoming Geological Museum and now (possibly) the Department of Geological Sciences at Michigan State University. I’ve heard other stories from various colleagues at numerous academic institutions about the loss (or feared loss) of personnel, that seems to go beyond the general economic hard times.

    In parallel, there has also been a general decline in geoscience student enrollments over the last 25 years (although the drop has plateaued over the last five years or so, and was actually up this year). This persistent low enrollment means that a large number of professional geoscientists will be reaching retirement age in the next 10 years, and there are not enough up-and-coming students to replace them.

    Why are geoscience enrollments relatively static or dropping, and what can we do to increase them?

  • Jen Carey '87 Publishes A Book: "What's So Great About Granite?"

    November 9, 2009

    Granite may be common, but it's no ordinary stone.

    Even if they don't know much about rocks, most people can name at least one place they have encountered granite. As a rock, granite is speckled, sparkly, and beautiful, and it is used in products we encounter every day, including countertops, headstones, and flooring. In the natural world, granite forms random boulders in fields and many of the planet's loftiest peaks. Granite is everywhere – from Georgia to Alaska and Maine to California – most states have somewhere with granite formations. Now, with What's So Great About Granite? written by Jennifer Carey, everyone can learn more about this enigmatic stone.

  • Laura Veirs '97 To Issue 7th Album Soon: "Wide Eyed, Legless"

    November 6, 2009

    Laura Veirs' seventh album July Flame is out January on her Raven Marching Band imprint. The collection includes appearances by Karl Blau, Jim James, and Eyvind Kang, among others. It also includes 13 gorgeous songs. See, for instance, standout "Wide-Eyed, Legless." We asked Veirs about it.

    "Wide-Eyed, Legless" is an evocative title. It sounds like a stage direction, a Beckett moment. What inspired the narrative? Is it an Andy Fairweather Low reference?
