North Carolina State University: Researchers Devise Hidden Dune Filters To Treat Coastal Stormwater Runoff

When it rains, untreated stormwater can sweep pollutants into coastal waters, potentially endangering public health. Now researchers from North Carolina State University have developed low-cost filtration systems that are concealed beneath sand dunes and filter out most of the bacteria that can lead to beach closures.

Scripps Institution of Oceanography: Scripps Scientists Discover ‘Lubricant’ for Earth’s Tectonic Plates

Scientists at Scripps Institution of Oceanography at UC San Diego have found a layer of liquefied molten rock in Earth’s mantle that may be acting as a lubricant for the sliding motions of the planet’s massive tectonic plates. The discovery may carry far-reaching implications, from solving basic geological functions of the planet to a better understanding of volcanism and earthquakes.

Daily Bulldog: UMF’s biggest geothermal project set to begin May 19
Some 80 geothermal wells will be dug in the heart of the University of Maine at Farmington campus starting this May. The $1.55 million project, which is expected to save upwards of 30,000 gallons of fuel oil each year, is part of the university’s goal of reaching carbon neutrality by 2035.

Science Daily: Suggestions for a Middle Ground Between Unlogged Forest and Intensively Managed Lands

In the world’s forested regions, two management systems — retention forestry and agroforestry — are being used to alleviate conflicts between preserving biodiversity and addressing human needs in production landscapes. A new article draws a parallel between the ecological effects of the two systems.

Scientific American: Noisy Ships Creep Out Crabs (Podcast)

The cacophony of ships at sea is stressing shore crabs and could be bothering other marine life.
