  • Green roofs to reduce the effects of climate change
    on November 10, 2017 at 4:39 pm

    It would be necessary to have between 207 and 740 hectares of green roofs in a city like Seville (Spain), depending on the scenario that is contemplated, to reduce the effects of climate change in relation to the maximum temperature rises of between 1.5 and 6 ºC that are estimated by the end of the century. This would require between 11 and 40 percent of the buildings in the city. […]

    on November 8, 2017 at 5:41 pm

    Elephants are often blamed for extensive loss of woody vegetation in Northern Botswana, but study results suggest that this may not be the case. […]

  • Signs may help history buffs get more buff
    on November 7, 2017 at 2:28 pm

    Visitors to the country's national parks and historic sites may be just a sign -- and a few steps -- away from improving their health and fitness while enjoying their park trips, according to a team of researchers. […]

  • Swapping where crops are grown could feed an extra 825 million people
    on November 6, 2017 at 4:19 pm

  • Fisheries given a solution to overharvesting
    on November 1, 2017 at 4:24 pm

    Many commercial fisheries are threatened by overharvesting. However, they can't address the problem because of inadequate scientific information, from overall population numbers to data on how fast fish grow and reproduce. Researchers have developed a model using information about landed fish catches and prices for any species. This model allows fisheries to net enough to meet rising demand while ensuring adequate income and replenishment of natural stocks. […]

  • From Cellulose to 3-D Objects
    on October 27, 2017 at 4:27 pm

    In our modern world, eliminating plastics is inconceivable. Unfortunately, they do have disadvantages, including the formation of CO(2) in both production and combustion, depletion of fossil feedstocks, and growth of landfills. Researchers have now introduced a new way forward, a polymer made entirely from biomass that can easily and inexpensively be used in 3-D printing. Objects produced in this way are of high quality, easily recyclable, and highly solvent-resistant. […]
