May 31, 2024 Burrowed into streambeds and rarely moving for their decades-long lifespans, freshwater mussels are biomonitors, meaning they indicate how clean their environment is, according to researchers. As the bivalves feed on organic matter and filter the water around them, their inner tissues and hard shells begin to reflect whatever is in their ...

May 31, 2024 An international team has found a new RNA virus that they believe is hitching a ride with a common human parasite. The virus is associated with severe inflammation in humans infected with the parasite Toxoplasma gondii, leading the team to hypothesize that it exacerbates toxoplasmosis ...

May 30, 2024 Plants and the animals that eat them have evolved together in fascinating ways, creating a dynamic interplay of survival strategies. Many plants have developed physical and chemical defenses to fend off herbivores. A well-known strategy in flowering plants is to produce nectar to attract 'ant bodyguards.' Recent research explores the evolution of this same defense strategy in ...

May 30, 2024 Research has led to a new tool for forecasting coral disease that could help conservationists step in at the right times with key interventions. Ecological forecasts are critical tools for conserving and managing marine ecosystems, but few forecasting systems can account for the wide range of ecological complexities in ...

May 30, 2024 Although dengue outbreaks cannot be prevented, it is possible to anticipate them. Scientists have recently identified a global climate indicator that may help improve predictions about the magnitude of dengue outbreaks several months in advance. This indicator, which can be used for any world region, is based on temperature fluctuations at the surface of the Indian Ocean. Obtaining reliable ...

May 28, 2024 Life evolved from simple geochemical processes present on the early Earth. However, the details of this transformation remain a mystery. In this study, researchers modeled the emergence of metabolic pathways from simple geochemical precursors and concluded that surprisingly few reactions in the history of metabolism may have been lost to ...

May 30, 2024 A great armada entered the North Atlantic, launched from the cold shores of North America. But rather than ships off to war, this force was a fleet of icebergs. And the havoc it wrought was to the ocean current itself. The future of the Atlantic circulation will be determined by a tug-o-war between Greenland's decreasing ice flux and its increasing freshwater ...

May 28, 2024 A new deep learning model performs a task that biologists have struggled with for centuries -- how to measure the incredibly complex process of embryonic development. Scientists have shown that the AI model, known as Dev-ResNet, can identify what happens and when during embryonic development, from video. While used in pond snail embryos for this study, in future the technique could be used to ...
