While observing the crayfish, the research team saw that the crustaceans exposed to low levels of the antidepressant were more adventurous and twice more likely to pop out of their shelters and explore their surroundings.

Crayfish Exposed to Antidepressants Are More Adventurous

While the traces of drugs found in waterways alter the crustacean’s behaviors, it may leave them more vulnerable to predation

New research finds oxygen levels in the world's temperate freshwater lakes are declining due to the rising temperatures caused by climate change.

Climate Change Is Draining the World’s Lakes of Oxygen

Hotter, longer summers are increasing water temperatures, which reduces lake oxygen levels, especially in deep waters

This July 9, 2020, photograph shows a 14th-century bell tower peeking out of Lake Resia in northern Italy. The building—and the historic town it once stood in—were submerged in an artificial lake in 1950 to generate power for a nearby hydroelectric plant.

Construction work revealed the foundations of Curon, a historic alpine town, for the first time since 1950

Researchers found that the bears could withstand an impact of up to 900 meters per second and shock pressures of up to 1.14 gigapascals (GPa). Any higher than those speeds, the seemingly invincible water bears turned to mush.

Water Bears Can Survive Impact Speeds of 1,845 Miles Per Hour

Tardigrades thrive in a variety of extreme conditions, so researchers wanted to know if they could withstand simulated space landing impacts
