  • Another Clue for Fast Motion of the Hawaiian Hotspot

    The island chain of Hawaii consists of several volcanoes, which are fed by a "hotspot". In geosciences a "hotspot" refers to a phenomenon of columnar shaped streams, which transport hot material from the deep mantle to the surface. Like a blow torch, the material burns through the Earth's crust and forms volcanoes. For a long time, it was assumed that these hotspots are stationary. If the tectonic plate moves across it, a chain of volcanoes evolves, with the youngest volcano at one end, the oldest at the other.

  • To Build Up Mussels, You Need to Know Your Fish

    Times are tough for 31 of Michigan’s 45 varieties of freshwater mussels. Sporting evocative names like wavy-rayed lampmussel and round pigtoe, these residents of the state’s rivers are imperiled by habitat disruption and pollution and are also threatened by climate change.

  • Scientists Monitor Crop Photosynthesis, Performance Using Invisible Light

    Twelve-foot metal poles with long outstretched arms dot a Midwestern soybean field to monitor an invisible array of light emitted by crops. This light can reveal the plants’ photosynthetic performance throughout the growing season, according to newly published research by the University of Illinois.

  • Improved Hubble Yardstick Gives Fresh Evidence for New Physics in the Universe

    Astronomers have used NASA's Hubble Space Telescope to make the most precise measurements of the expansion rate of the universe since it was first calculated nearly a century ago. Intriguingly, the results are forcing astronomers to consider that they may be seeing evidence of something unexpected at work in the universe.

  • ​Could Cleaning Up Beaches Make Americans Better Off?

    Cleaning up beaches could boost local economies in addition to preserving natural treasures and animal habitats.

    In southern California’s Orange County alone, the economic benefits of beach cleanup could range from $13 per resident in a three-month period if debris were reduced by 25 percent to $42 per resident with a 75 percent drop in plastics and other trash along the oceanfront, according to a new study. That could mean up to a $46 million boost to the county’s economy in just one summer.

  • Scientists Discover Key Gene for Producing Marine Molecule with Huge Environmental Impacts

    Researchers at the University of East Anglia have discovered a key gene for the synthesis of one of the world’s most abundant sulfur molecules.

    Dimethylsulfoniopropionate (DMSP) is an important nutrient in marine environments with more than one billion tonnes produced annually by marine phytoplankton (microscopic plant-like cells), seaweed and bacteria.

  • Weather Should Remain Predictable Despite Climate Change

    According to the Intergovernmental Panel on Climate Change, temperatures are expected to rise between 2.5 and 10 degrees Fahrenheit over the next century. This warming is expected to contribute to rising sea levels and the melting of glaciers and permafrost, as well as other climate-related effects. Now, research from the University of Missouri suggests that even as rising carbon dioxide levels in the atmosphere drive the climate toward warmer temperatures, the weather will remain predictable.

  • Urban Heat Island Effects Depend on a City’s Layout

    The arrangement of a city’s streets and buildings plays a crucial role in the local urban heat island effect, which causes cities to be hotter than their surroundings, researchers have found. The new finding could provide city planners and officials with new ways to influence those effects.
