Trees cool their environment  and "heat islands" like Munich benefit from it. However, the degree of cooling depends greatly on the tree species and the local conditions. In a recent study, scientists at the Technical University of Munich (TUM) compared two species of urban trees.

 Today, the U.S. Geological Survey (USGS) and the U.S. Department of Energy (DOE), in partnership with DOE’s Lawrence Berkeley National Laboratory and the American Wind Energy Association, released the United States Wind Turbine Database (USWTDB) and the USWTDB Viewer to access this new public dataset.

Nestled among giant fish tanks at the California Academy of Sciences, there's a black box—just big enough to hold six aquariums and maybe five humans. What it lacks in size, though, it makes up for in preciousness: Running here is a experiment that could help save corals from annihilation.

The vampire bat lives up to its name. Its diet consists of blood, which it gets by biting animals and lapping up their blood. The vampire bat prefers to feed on domestic animals such as cows and pigs. When it does so, there is a risk of transmission of pathogens such as rabies. Now, a new study lead by Assistant Professor Kristine Bohmann from the Natural History Museum of Denmark, University of Copenhagen, describes a new DNA method to efficiently screen many vampire bat blood meal and faecal samples with a high success rate and thereby determine which animals the vampire bats have fed on blood from. Furthermore, the authors show that the technique can be used to simultaneously assess the vampire bat’s population structure.

Among the most damaging effects that climate change has wrought on the natural world are those sustained by coral reefs.
