New research warns of declining access to safe, reliable and affordable water in the U.S., urging for better water tracking tools and immediate policy reforms.

Research published in Proceedings of the National Academy of Sciences confirms that fossilized marine invertebrates serve as a powerful tool for understanding long-term ecological change and informing modern conservation efforts.

New Arizona State University research reveals the extent to which sewage pollution threatens the fragile coral reef ecosystems of West Hawaiʻi Island. The study identifies exactly where sewage-contaminated water is entering the ocean, further damaging coral reefs already impacted by climate change, and endangering human health. The research team used advanced airborne mapping techniques, along with comprehensive field sampling and sophisticated statistical models, to pinpoint locations where high levels of fecal bacteria associated with populated coastal areas are driving worsening contamination. The study provides the critical data needed by government officials and local communities to mitigate this threat and protect the health and biodiversity of coastal ecosystems.

Researchers have shown for the first time how hidden motions could control how granular materials such as soil and snow slip and slide, confirming a long-suspected hypothesis. The knowledge could help in understanding how landslides and avalanches work and even help the construction industry in the future.
