"Greening" stormwater in Philadelphia

When environmental geologist David Wilcots joined Sci-Tek Consultants in 2014, he became involved with the Philadelphia Water Department’s Green Stormwater Infrastructure project. Sci-Tek’s goal was to redesign certain areas of the city’s urban landscape so that “less stormwater goes into the sewage system” and more goes into the ground, explains Wilcots.

Beavers preserve wetlands in water-stressed areas

Once considered detrimental to ecosystems and nuisances where, for example, dams flooded farmland, beavers have been rhetorically touted in recent years as a potential boon for wetland health and water conservation. Anecdotal accounts and qualitative findings have suggested beavers improve water quality and availability in drought-stressed ecosystems, but just how much influence they have was not known. In new research, scientists have examined two creeks in Nevada to directly measure how effective beaver dams are at slowing water flows and storing water through the dry summer months.

Evidence of devastating drought found beneath the Dead Sea

The Dead Sea, a landlocked lake bordered by Israel, Jordan and Palestine, is nearly 10 times saltier than the ocean. And it’s getting saltier. Since the beginning of the 20th century, the water level has dropped by nearly 30 meters, largely because of diversions of the Jordan River, the lake’s primary tributary and the arid region’s main source of fresh water.

Martian channels carved by lava, not water?

A complex system of river-like channels on Mars widely thought to have been formed by flowing water could instead have been carved by a huge lava flow, according to a new study. The findings could affect our understanding of how supportive Mars might have been for life in the past.

Ceres' homemade organic materials

Researchers analyzing data from NASA’s Dawn spacecraft have found signs of organic compounds that arose on the surface of Ceres, a dwarf planet one-fourth the diameter of our moon in the asteroid belt between Mars and Jupiter. The compounds’ origins may provide clues about how life on Earth got started.
