Paris staged a high-diving demonstration in the reclaimed Seine to showcase the river’s potential as a venue for sport and public events, signaling ongoing river-restoration ambitions and the city’s interest in using waterways for athletic competitions.
Romanian authorities rushed to sink four barges into the Danube to secure the cooling-water intake for the nuclear plant’s second reactor, a move aimed at preventing a shutdown and keeping the facility operating amid pressing reliability concerns.
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.
The Strait of Hormuz—the global oil lifeline—has been blocked amid Iran’s war, and reopening it is a high-stakes, complex challenge with potential ripple effects on global energy markets and regional security.
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.
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.
