Salmon Exposed to Cocaine Swim Farther, Signaling Environmental Drug Pollution

A study of 105 wild Atlantic salmon in Sweden’s Lake Vattern found fish exposed to cocaine and its metabolite benzoylecgonine swam about 1.9 times farther per week than unexposed fish, with the metabolite exposure adding roughly 7.6 extra miles — highlighting how pharmaceuticals in waterways are altering wildlife behavior and underscoring the need for improved wastewater treatment and monitoring, with related notes on sharks also ingesting drugs in other regions.

Possible Evidence of Martian River Found in Perseverance Rover Images.

Possible Evidence of Martian River Found in Perseverance Rover Images.

New images taken by NASA’s Perseverance rover may show signs of what was once a deep and fast-moving river on Mars, part of a network of waterways that flowed into Jezero Crater. Understanding these watery environments could help scientists in their efforts to seek out signs of ancient microbial life that may have been preserved in Martian rock. The rover is exploring the top of a fan-shaped pile of sedimentary rock that stands 820 feet tall and features curving layers suggestive of flowing water.

Tulare Lake Refills, Affects Kings County Farmland.

Tulare Lake Refills, Affects Kings County Farmland.

The Tulare Lake Basin in Kings County, California is experiencing floodwater covering a large area of agricultural land due to increased flow in all waterways leading to the basin, causing Tulare Lake to reemerge for the first time since 1982-83. The lake was known in the late 1800s as the largest freshwater lake in the western United States. The re-emergence is expected to last through the summer, and there is no natural outflow for the water, so it will be eliminated through evaporation or irrigation. The Kings County Sheriff is reminding everyone that the Tulare Lake Basin is private farmland, and trespassing will be enforced.
