A strong earthquake shook buildings in the Chilean capital of Santiago on Wednesday but there were no immediate reports of damage or injuries, and the country's massive copper mines were not affect

After a downturn during the 1990s, global investments in hydropower infrastructure have begun to rise.

Landslides killed more than 32,000 people across the world from 2004 to 2010 - up to 10 times more than previously thought, the first detailed study of the disasters showed on Thursday.

Antimicrobials used in salmon aquaculture pass into the marine environment. This could have negative impacts on marine environmental biodiversity, and on terrestrial animal and human health as a result of selection for bacteria containing antimicrobial resistance genes. We therefore measured the numbers of culturable bacteria and antimicrobial-resistant bacteria in marine sediments in the Calbuco Archipelago, Chile, over 12-month period at a salmon aquaculture site approximately 20 m from a salmon farm and at a control site 8 km distant without observable aquaculture activities.

A two-day meeting hosted the by US of 17 countries opposed to the EU's emissions trading system (ETS) has ended without a joint declaration.

Promotion of physical activity is a priority for health agencies. We searched for reviews of physical activity interventions, published between 2000 and 2011, and identified effective, promising, or emerging interventions from around the world. The informational approaches of community-wide and mass media campaigns, and short physical activity messages targeting key community sites are recommended.

Deciphering ecological effects of major catastrophic events such as earthquakes, tsunamis, volcanic eruptions, storms and fires, requires rapid interdisciplinary efforts often hampered by a lack of pre-event data. Using results of intertidal surveys conducted shortly before and immediately after Chile's 2010 Mw 8.8 earthquake along the entire rupture zone (ca. 34–38°S), we provide the first quantification of earthquake and tsunami effects on sandy beach ecosystems. Our study incorporated anthropogenic coastal development as a key design factor.

Imprecise measurement of physical activity variables might attenuate estimates of the beneficial effects of activity on health-related outcomes. The researchers aimed to compare the cardiometabolic risk factor dose-response relationships for physical activity and sedentary behaviour between accelerometer- and questionnaire-based activity measures.

Chile's Supreme Court suspended a key permit for Canadian miner Goldcorp Inc's El Morro copper-gold project, the latest setback for the controversial project and one of the biggest legal blows to a

Peru became the latest developing country to enact a domestic climate change initiative in the absence of a binding global pact, adopting a resolution on Thursday to lower carbon emissions in its f
