Researchers reconstructed the Indus River's discharge over 30 million years and found a significant change in sediment source five million years ago. The study suggests that rivers were diverted from their original southeasterly flow by uplifted mountain ranges in modern-day Pakistan.

Researchers at NIST discovered that acetaminophen, a widely used pain reliever, transforms into 11 new toxic compounds when exposed to chlorine disinfection in wastewater. The study highlights the need for environmental scientists to consider downstream reaction products when assessing pharmaceutical impacts on the environment.
