  • Prairie-chicken nests appear unaffected by wind energy facility
    on August 9, 2017 at 11:33 am

    Wind energy development in the Great Plains is increasing, spurring concern about its potential effects on grassland birds, the most rapidly declining avian group in North America. However, a new study suggests that for one grassland bird species of concern -- the greater prairie-chicken -- wind energy infrastructure has little to no effect on nesting. Instead, roads and livestock grazing remain the most significant threats to its successful reproduction. […]

    on August 4, 2017 at 4:40 pm

    Low- and middle-income countries such as Brazil face a lack of epidemiological data, and one of the key priorities for researchers is developing high-quality surveys. Investigators have now studied the difficulties in conducting a longitudinal epidemiological survey in a school-based sample in Brazil. […]

  • Scientists link biodiversity genomics with museum wisdom through new public database
    on August 3, 2017 at 6:11 pm

    A new publicly available database will catalog metadata associated with biologic samples, making it easier for researchers to share and reuse genetic data for environmental and ecological analyses. It links publicly available genetic data to records of where and when samples were collected. Such information is critical for comparing biodiversity in different locations worldwide, across time. Despite calls for more data sharing within the research community, researchers have until now lacked the tools they needed. […]

  • Vertical axis wind turbines can offer cheaper electricity for urban and suburban areas
    on August 3, 2017 at 2:31 pm

    Small vertical axis wind turbines (VAWTs) possess the ability to effectively operate in the presence of high turbulent flow, which makes them ideal energy harvesting devices in urban and suburban environments. In a new article, researchers present results indicating that an optimally designed VAWT system can financially compete with fossil-fuel based power plants in urban and suburban areas, and even spearhead the development of a net-zero energy building or city. […]

    on July 27, 2017 at 2:29 pm

    A team of researchers has recently completed a global study on the trade-offs between the benefits provided by tropical forests and its conversion for agricultural use. The team examined deforestation activities of more than 50 countries in the tropics between 2000 to 2012, and identified regions where deforestation is most and least beneficial. […]

  • From volunteer to decision-maker: How parents can play a greater role in schools
    on July 24, 2017 at 8:21 pm

    Schools tend to offer parents opportunities to volunteer that not only reinforce the top-down power structure of schools, but also cater to mostly white, privileged families, maintaining the institutionalized racism that marginalizes low-income families and families of color. What schools and districts can do instead is partner with families in meaningful ways. […]

  • Tough robots making an ImPACT
    on July 21, 2017 at 2:46 pm

    New and improved rescue robots tough enough to function in extreme and hostile environments were unveiled recently at a demonstration at Tohoku University, Japan. […]

  • Shale gas development spurring spread of invasive plants in Pennsylvania forests
    on July 20, 2017 at 6:23 pm

    Vast swaths of Pennsylvania forests were clear-cut circa 1900 and regrowth has largely been from local native plant communities, but a team of researchers has found that invasive, non-native plants are making significant inroads with unconventional natural gas development. […]

  • Search and rescue dogs do their jobs despite travel stress
    on July 20, 2017 at 3:36 pm

    When disaster strikes, you want the very best tools, functioning at their peak. In the case of catastrophic earthquakes, tornadoes, or even bombings in war zones, those tools are search and rescue dogs. But researchers have found that getting dogs to disaster sites can add to the animals' stress. […]

  • Conserve intact forest landscapes to maximize biodiversity, reduce extinction risk
    on July 19, 2017 at 5:22 pm

    A new global analysis of forest habitat loss and wildlife extinction risk shows that species most at risk live in areas just beginning to see the impacts of human activities such as hunting, mining, logging and ranching. […]

  • Regulating the indirect land use carbon emissions imposes high hidden costs on fuel
    on June 27, 2017 at 2:54 pm

    Biofuel policies like the Low-Carbon Fuel Standard in California are trying to minimize the indirect land use change related emissions by accounting for the indirect land use change factor as part of the carbon emissions per gallon of biofuels. A new study examines the costs and benefits of using this approach at a national level. […]
