How a common fungus eliminates toxic mercury from soil and water

Mercury pollution of soil and water is a worldwide threat to public health. This new work suggests Metarhizium could provide an inexpensive and efficient way to protect crops grown in polluted areas and remediate mercury-laden waterways. The study, which was conducted by UMD professor of entomology Raymond St. Leger and researchers in the laboratory of …

Container ship accidents are a little understood but emerging threat to marine ecosystems

However, not all this cargo makes it to market. Fires, collisions, groundings and other seaborne accidents can lead to containers spilling overboard and sinking to ocean floors where they and their contents pollute the marine environment. In a new paper published in the Journal of Cleaner Production, a group of Concordia researchers under the supervision …

Study shows how to boost early intervention for climate-related health risks

In fact, early warning systems designed to do just this have been developed in recent years to help control outbreaks of malaria, dengue fever and other diseases in parts of the Tropics. But their implementation has been undercut by funding uncertainties, overburdened local health systems, insufficient training for local health technicians, and a lack of …

New discoveries made about a promising solar cell material, thanks to new microscope

Richard Kim, a scientist from Ames Lab, explained the two features that make the new scanning probe microscope unique. First, the microscope uses the terahertz range of electromagnetic frequencies to collect data on materials. This range is far below the visible light spectrum, falling between the infrared and microwave frequencies. Secondly, the terahertz light is …

Understanding a cerium quirk could help advance grid-scale energy storage

Flow batteries are one of the methods under consideration for storing intermittent sources of renewable electricity, such as solar and wind power. They can bank large quantities of energy by keeping the chemical potential in liquid form, with two electrolytes that flow through porous electrodes to charge and discharge. The metal cerium could store energy …
