Impact of wastewater systems on Edwards Aquifer evaluated
Researchers developed an integrated hydrologic computer model to evaluate the impact of different types of wastewater disposal facilities on the Edwards Aquifer, the primary water source for San Antonio and its surrounding communities. The research results will guide authorities on what actions to take to protect the quality and quantity of water entering the aquifer.
75 ways Trump made America dirtier and the planet warmer
“I want crystal clean water and air.” That’s what Donald Trump said in the first chaotic presidential debate with Joe Biden. But there is scant evidence of that desire in the actions of his administration, which has spent nearly four…

Management of a popular game fish, the smallmouth bass
For recreational fishing enthusiasts, the thrill of snagging their next catch comes with discovering what’s hooked on the end of the line. In many freshwater streams and rivers — across the central and eastern parts of the U.S. — anglers are often catching a popular freshwater game fish: the smallmouth bass. Now, scientists have discovered a new level of biodiversity within that species.
Cheaters don’t always win: Species that work together do better
The sign of a healthy personal relationship is one that is equally mutual – where you get out just as much as you put in. Nature has its own version of a healthy relationship. A team of researchers investigated these interactions, known as mutualisms, and why they are so critical for healthy environments.

Severe air pollution drives food delivery consumption and plastic waste
When the air outside is bad, office workers are more likely to order food delivery than go out for lunch, which in turn increases plastic waste from food packaging, according to a study by researchers from the National University of Singapore.
Driver of the largest mass extinction in the history of the Earth identified
252 million years ago, at the transition from the Permian to the Triassic epoch, most of the life forms existing on Earth became extinct. Using latest analytical methods and detailed model calculations, scientists have now succeeded for the first time to provide a conclusive reconstruction of the geochemical processes that led to this unprecedented biotic crisis.
Early-arriving endangered Chinook salmon take the brunt of sea lion predation
A new study found that sea lions have the largest negative effect on early-arriving endangered Chinook salmon in the lower Columbia River.
Oldest securely dated evidence for a river flowing through the Thar Desert, Western India
(Max Planck Institute for the Science of Human History) Using luminescence dating of ancient river sediments, a new study published in Quaternary Science Reviews presents evidence for river activity at Nal Quarry in the central Thar Desert starting from approx. 173 thousand years ago. These findings represent the oldest directly dated phase of river activity in the region and indicate Stone Age populations lived in a distinctly different Thar Desert landscape than we encounter today.
