Deadly effects of certain kinds of household air pollution lead to call for biomarker studies

Posted: 01 Apr 2013 03:13 PM PDT

Almost 4 million people die annually from household air pollution (HAP) caused by exposure to the combustion of biomass fuels, kerosene, or coal. A new article explains the need for studies into biomarkers of HAP exposure and predictors of respiratory disease.

Extreme algal blooms: The new normal?

Posted: 01 Apr 2013 12:10 PM PDT

A research team has determined that the 2011 record-breaking algal bloom in Lake Erie was triggered by long-term agricultural practices coupled with extreme precipitation, followed by weak lake circulation and warm temperatures. The team also predicts that, unless agricultural policies change, the lake will continue to experience extreme blooms.

By keeping the beat, sea lion sheds new light on animals’ movements to sound
