Canadian ecologists have discovered that antidepressants and opioids accumulate in the tissues of small river fish living downstream from wastewater treatment plants. The study revealed gender differences in toxin accumulation and proposed a new analytical method to assess the impact of pharmaceutical pollution on aquatic ecosystems.
For many years, residents of Central Africa have told stories about fish capable of climbing waterfalls. Now, these accounts have received scientific confirmation: Parakneria thysi have been captured on video as they scaled a 15-meter waterfall. The study reveals the unique mechanisms behind their vertical movement and highlights the distinctive features of their migration.
A new study has shown that the sleep and activity patterns of fish in the early stages of life can predict their lifespan. These behavioral patterns are linked to internal biological changes and may serve as indicators of health and aging.
