University Of Utah Scientists Study Microbial Lifeforms In High pH Springs

Oddly enough, rocks don’t always need heat and pressure to metamorphosize. In the process of serpentinization , rocks actually change with a reduction in both heat and pressure. This process is underway in many places around the world, and researchers at the University of Utah are working to better understand it as well as the extremophile lifeforms that reside in the water bodies nearby. In one investigation, scientists at the university are sampling along the Tablelands Ophiolite in Canada’s Gros Morne National Park. Ultramafic rocks at this site, marked by low silica contents and rich mineral levels, are undergoing serpentinization and playing a role in the creation of highly basic natural springs that vent hydrogen and methane gas.

Flood Warning Systems

Chapter Overview: Flood Warning A Real-Time Solution Streamflow Measurements Typical Flood Warning System Monitoring Location Data Management Quality Assurance Recommended Equipment Why Monitoring Matters While some areas are more prone to flooding than others, the establishment of flood warning systems near any major waterway or body of water provides critical information that can protect property and save lives. Of course, the most effective flood warning methods extend beyond the installation of gages and telemetry equipment, and employ qualified staff and carefully designed procedures to provide the earliest warning about whether a flood should be expected, when it will occur, and how severe it will be.

Pollutants In Fish May Inhibit Human Immune System

Pollutants in fish aren’t good, and we have reported on the persistence with which they still affect populations in the oceans today. But there are still other impacts of pollutants that have gone undescribed. In recent research from scientists at the Scripps Institution of Oceanography , it’s been shown that pollutants in ocean fish may actually inhibit the immune systems of humans. The researchers say that their results, published in the April 15 edition of the journal Science Advances , could one day be used to better assess the risks posed to human health by eating fish tainted by persistent organic pollutants. The crux of the findings have to do with a certain protein that humans use to get rid of pollutants, called P-gp.

Zebra Mussels Impact Lake Minnetonka

Researchers at the Minnehaha Creek Watershed District have just released the results of a five-year investigation into the impacts that zebra mussels in Lake Minnetonka have had on the lake’s water quality. Their findings reveal a lot of variation in the mussels’ effects, thanks partly to the lake’s numerous bays. In some of the water body’s bays, there are more zebra mussels while there are fewer in others. In those areas with more mussels, scientists with the District have found the biggest changes to water quality. In Wayzata Bay, where the mussel population topped out at an estimated 200,000 zebra mussels per square meter in 2014, there has been an increase in water clarity and a decrease in algae and phosphorus.
