  • Biochar shows benefits as manure lagoon cover
    on August 9, 2017 at 6:02 pm

    Manure is a reality in raising farm animals. Manure can be a useful fertilizer, returning valued nitrogen, phosphorus, and potassium to the soil for plant growth. But manure has problems. Odor offensiveness, gas emissions, nutrient runoff, and possible water pollution are just a few. New methods may reduce these negatives while potentially adding some positives: biochar covers. […]

  • Biochar could clear the air in more ways than one
    on July 27, 2017 at 2:29 pm

    Biochar could reduce local air pollution from agriculture by reducing emissions of nitric oxide from soil. Researchers argue that a better understanding of nitric oxide response to biochar will save lives and money, especially on farms near urban areas where agricultural emissions contribute to ozone and particulate matter formation.

  • First oceans may have been acidic
    on April 10, 2017 at 1:56 pm

    New research has looked to the distant past -- all the way back to Earth's earliest oceans. A newly developed model suggests that the early oceans, right around the time that life originated, were somewhat acidic, and that they gradually became alkaline. […]

  • Will grass become the new gasoline?
    on March 31, 2017 at 4:18 pm

    A new process that turns grass into biofuel has been developed by scientists. Although it might sound revolutionary, there’s still a lot to do before this becomes reality, however. Right now the amount of biofuel that can be made from grass is still limited to a few drops. But the researchers ask, will we soon be driving on "grassoline?" […]

  • Unexpected result: Ocean acidification can also promote shell formation
    on January 27, 2017 at 4:29 pm

    More carbon dioxide in the air also acidifies the oceans. It seemed to be the logical conclusion that shellfish and corals will suffer, because chalk formation becomes more difficult in more acidic seawater. But now a group of scientists discovered to their own surprise that some tiny unicellular shellfish (foraminifera) make better shells in an acidic environment. This is a completely new insight. […]

  • First detection of ammonia in the upper troposphere
    on December 5, 2016 at 2:56 pm

    Population is growing, climate is warming -- hence, emission of ammonia (NH3) trace gas from e.g. agriculture will increase worldwide. Recently, scientists for the first time have detected NH3 in the upper troposphere. They analyzed satellite measurements by the MIPAS infrared spectrometer and found increased amounts of NH3 between 12 and 15 km height in the area of the Asian monsoon. This suggests that the gas is responsible for the formation of aerosols, smallest particles that might contribute to cloud formation. […]

  • More frequent, more intense and longer-lasting storms cause heavier spring rain in central US
    on December 1, 2016 at 9:48 pm

    Intense storms have become more frequent and longer-lasting in the Great Plains and Midwest in the last 35 years. What has fueled these storms? The temperature difference between the Southern Great Plains and the Atlantic Ocean produces winds that carry moisture from the Gulf of Mexico to the Great Plains, according to a recent study. […]
