Blame it on the rain: Study ties phosphorus loading in lakes to extreme precipitation events

Thu, 11 Jan 2018 14:01:00 EST

While April showers might bring May flowers, they also contribute to toxic algae blooms, dead zones and declining water quality in U.S. lakes, reservoirs and coastal waters, a new study shows.(image)



In urban streams, pharmaceutical pollution is driving microbial resistance

Wed, 10 Jan 2018 11:11:00 EST

In urban streams, persistent pharmaceutical pollution can cause aquatic microbial communities to become resistant to drugs. So reports a new study published today in the journal Ecosphere. (image)



U.S. Waterways Are Getting Saltier, With Possible Effects on Drinking Water

Wed, 10 Jan 2018 09:52:00 EST

Streams and rivers across much of the U.S. are getting saltier and more alkaline due to an uptick in the use of road deicers and fertilizers in recent decades, according to a  50-year-long analysis of 232 monitoring sites by the U.S. Geological Survey.(image)



In urban streams, pharmaceutical pollution is driving microbial resistance

Tue, 09 Jan 2018 11:01:00 EST

Resilient bacteria might help streams but could threaten human health(Millbrook, NY) In urban streams, persistent pharmaceutical pollution can cause aquatic microbial communities to become resistant to drugs. So reports a new study published today in the journal Ecosphere. Emma Rosi, an aquatic ecologist at the Cary Institute of Ecosystem Studies and lead author on the study explains, "Wastewater treatment facilities are not equipped to remove many pharmaceutical compounds. We were interested in how stream microorganisms - which perform key ecosystem services like removing nutrients and breaking down leaf litter - respond to pharmaceutical pollution." (image)



Frog genome mapping sheds new light on environmental contaminants

Tue, 09 Jan 2018 08:24:00 EST

A University of Victoria molecular biologist has gained new insights into how environmental contaminants may disrupt thyroid systems. The discovery was made while assembling the genome of the North American bullfrog.Caren Helbing’s findings could help explain the mechanisms of early development, as well as how environmental contaminants cause thyroidrelated diseases and malfunctions.(image)



NUS Researchers Pioneer Water-Based, Eco-Friendly and Energy-Saving Air-Conditioner

Mon, 08 Jan 2018 16:01:00 EST

A team of researchers from the National University of Singapore (NUS) has pioneered a new water-based air-conditioning system that cools air to as low as 18 degrees Celsius without the use of energy-intensive compressors and environmentally harmful chemical refrigerants. This game-changing technology could potentially replace the century-old air-cooling principle that is still being used in our modern-day air-conditioners. Suitable for both indoor and outdoor use, the novel system is portable and it can also be customised for all types of weather conditions.(image)



US Rivers and Streams are Compromised by Increasing Salt Loads

Mon, 08 Jan 2018 15:53:00 EST

Human activities are exposing US rivers and streams to a cocktail of salts, with consequences for infrastructure and drinking water supplies. So reports a new study in the Proceedings of the National Academy of Sciences that is the first to assess the combined, long-term changes in freshwater salinity and alkalization across the country.(image)
