How can we tell if new chemicals will cause damage to humans before they are made?
The world has long attributed Tibetan wisdom to the Buddhist monks and their teachings, but largely ignored the wisdom of the nomads. Recently, scientists have proven that traditional grazing practiced by these nomads are crucial for Tibetan rangelands, promoting plant diversity and nectar production.

Household air pollution and contaminated drinking water are the two leading causes of death among children under the age of five in Rwanda. A recent study investigated the effectiveness of using cookstoves and water filters to improve children's health.
Shale gas and oil production have been associated with earthquakes in several parts of the world. New research shows that in the United Kingdom, human activities have caused earthquakes in the past and more fracking will likely increase the frequency of earthquakes.
Anyone with a smartphone can add to the collective understanding of science, including data that can help us understand changes in animal behavior. But how good is the data they collect and is it usable?
Can social media reduce disaster impacts? If so, how much? A recent study successfully explored the influence of social media in reducing financial damages during the 2011 Bangkok flood and quantified the impact.
