Researchers at Northeastern University used machine learning to aggregate nearly five decades of weather data to better understand the factors that lead to New England flooding.

For years, the Endangered Species Act has been interpreted in a way that preserves the environments where endangered and threatened plants and animals live. A proposed regulatory change by the Trump administration would limit the act’s protection to prohibit killing, harming or injuring individual animals and not the habitats on which they rely, some experts say.

Salt marshes are among coastal habitats endangered by both rising sea levels and urban development. Preserving and restoring salt marshes is essential not only for wildlife protection and natural flood mitigation, but also for the numerous ecosystem services — such as carbon storage, bird watching and fishing — they provide to urban dwellers.
