    Many Midwestern retailers sell mislabeled invasive vines

    Gardeners hoping to celebrate the beauty of American bittersweet – a native vine that produces orange berries in the fall and is used for wreaths – may be unwittingly buying an invasive bittersweet instead. That’s because many Midwestern retailers are selling oriental bittersweet with labels misidentifying it as the native plant, researchers report. These sales are occurring in stores and online.

  • From left, Matthew Hudson, Arian Avalos, Gene Robinson and their colleagues found genomic signatures associated with the evolution of gentle behavior in Puerto Rico’s Africanized honey bees.

    Genomic study explores evolution of gentle ‘killer bees’ in Puerto Rico

    A genomic study of Puerto Rico’s Africanized honey bees – which are more docile than other so-called “killer bees” – reveals that they retain most of the genetic traits of their African honey bee ancestors, but that a few regions of their DNA have become more like those of European honey bees. According to the researchers, these changes likely contributed to the bees’ rapid evolution toward gentleness in Puerto Rico, a change that occurred within 30 years.

    Corn better used as food than biofuel, study finds

    Corn is grown not only for food, it is also an important renewable energy source. Renewable biofuels can come with hidden economic and environmental issues, and the question of whether corn is better utilized as food or as a biofuel has persisted since ethanol came into use. For the first time, researchers at the University of Illinois have quantified and compared these issues in terms of economics of the entire production system to determine if the benefits of biofuel corn outweigh the costs.

  • A new study reconfigures the elephant family tree, placing the giant extinct elephant Palaeoloxodon antiquus closer to the African forest elephant, Loxodonta cyclotis, than to the Asian elephant, Elephas maximus, which was once thought to be its closest living relative.

    Genetic study shakes up the elephant family tree

    New research reveals that a species of giant elephant that lived 1.5 million to 100,000 years ago – ranging across Eurasia before it went extinct – is more closely related to today’s African forest elephant than the forest elephant is to its nearest living relative, the African savanna elephant.

  • Chill-tolerant hybrid sugarcane also grows at lower temperatures, team finds

    U.S. farmers have long hoped to extend sugarcane’s growing range northward from the Gulf coast, substantially increasing the land available for sugar and biofuels. Several hybrid canes developed in the 1980s have proved hardy in cooler climes, surviving overwinter as far north as Booneville, Arkansas. But until now, no one had tested whether these “miscanes,” as they are called, actually photosynthesize, and thus continue to grow, when the thermometer dips.

  • Groundwater from three main aquifers in the United States contributes to food shipped across the country and around the globe, says a new study from civil and environmental engineers at Illinois and Lehigh University.

    Study: Groundwater from aquifers important factor in food security

    CHAMPAIGN, Ill. — Thirsty cities, fields and livestock drink deeply from aquifers, natural sources of groundwater. But a study of three of the most-tapped aquifers in the United States shows that overdrawing from these resources could lead to difficult choices affecting not only domestic food security but also international markets.
