Science & Discovery News Today — August 27, 2026

As scientists continue to study the far-reaching impacts of climate change, we're seeing its effects manifest in various ecosystems around the world. In the United States, America's largest reservoir, Lake Mead, is bearing the scars of a changing climate, with water levels and quality being significantly affected. Meanwhile, in the Galápagos, researchers have made a surprising discovery about the behavior of yellow sea turtles, with some individuals showing a strong preference for staying in their home territories. This kind of localized behavior is crucial to understand, especially as cities and regions develop climate plans to adapt to a changing world.

Green spaces are a key component of these plans, but a new study suggests that they're being underutilized in European cities, despite their potential to help mitigate the effects of climate change. Unfortunately, not all ecosystems are faring as well. In Australia, populations of lizards and snakes are declining at an alarming rate, highlighting the urgent need for conservation efforts. As researchers work to better understand these trends, they're also exploring natural processes that could help mitigate climate change, such as basalt weathering, which may have a more limited impact on CO2 levels than previously thought. On a more promising note, a new study on seed germination has shed light on the remarkable ability of dry seeds to preserve fully formed mitochondria, allowing for rapid energy production when conditions are right.
