Novel Fungus Helps Beetles to Digest Hard Wood
Credit: Joshua Peter Kaffer The Asian longhorned beetle's ability to feed on wood may shed light on novel mechanisms for breaking down lignin, possibly for the biofuel industry.
Future Impact of Global Warming is Worse When Grazing Animals are Considered, Scientists Suggest
Credit: Eric Post, Penn State Post and Pederson believe that grazing by muskoxen, such as the one in the photograph, and caribou may reduce the carbon-mitigating benefit of plants in the Arctic.
