Read moreThe biodiversity buzz is alive and well in Fiji, but climate change, noxious weeds and multiple human activities are making possible extinction a counter buzzword. Just as Australian researchers are finding colourful new bee species, some of them are already showing signs of exposure to environmental changes.
Read moreWith the help of advanced genetic testing and hundreds of frog skin swabs, an international team of researchers has created the most complete map to date of when and where different genetic variants of the frog-killing Batrachochytrium dendrobatidis have infected frog populations around the world. The investigation also uncovered a whole new genetic lineage of the fungus, one that appears to have originated in Asia and may be the oldest variant yet discovered.
Read moreAn increase in the generation of wind energy is a key component of the U.S. strategy to reduce carbon emissions from the power sector. Approximately 97 gigawatts of wind energy production capacity are currently installed in the U.S., and in 2018, wind energy supplied about 6.5% of the nation's electricity. Scenarios developed by various groups, including U.S. Department of Energy, indicate that a four- to five-fold expansion over current levels of electricity produced by wind is needed by the year 2050 to help meet U.S. carbon emission reduction goals.
