Survey by researchers in 16 countries is published in Science. Authors say chytrid fungus is responsible for heaviest biodiversity loss ever caused by a single pathogen.

Using a combination of crop models and expertise from farmers and others -- and applying them to our current trajectory of high greenhouse gas emissions -- scientists built a tool to assess climate risk vulnerability to help pinpoint communities in need of support for adaptation and mitigation. The study was carried out in Vietnam, Uganda and Nicaragua -- developing countries that embody many of the climate shocks in store for the coming decades, including droughts, floods and high temperatures.

Long-distance migrations are common for large whales, but when in their evolutionary past did whales begin to migrate and why? Scientists from the Smithsonian Tropical Research Institute and the University of California, Berkeley looked for these answers in fossil whale barnacles.

Few novel drugs have been developed to treat neglected diseases in recent decades, Brazilian researchers warn.

Researchers used C. elegans as an animal model to investigate the importance of certain human genes for the treatment of schizophrenia.

Dysregulation of the signaling pathway known as the beta-catenin-dependent Wnt can also cause embryo malformation and contribute for the development of breast and cervical cancer.

The back-and-forth relationship between insects and their food plants may drive tropical biodiversity evolution according to work on Barro Colorado Island's 50 hectare plot in Panama.
