That might surprise Delaware Valley residents accustomed to hearing how scarce the once-abundant fish are. But while shad have long suffered in their home range, they have flourished out West. The sleek silver herring is a celebrity

On Feb. 11, 2025, U.S. Sen. Ted Cruz released a database of 3,483 National Science Foundation grants that the Senate Commerce Committee, headed by Cruz, described in a press release as “woke DEI grants.” Cruz had previously used the list of grants to prepare an October 2024 report claiming that the Biden administration had politicized

As head of the Delaware Riverkeeper Network, she led a three-decade battle against the Port of Philadelphia’s plan to deepen the Delaware River’s main shipping channel. Despite environmental concerns and a lengthy lawsuit, the project

In September 2024, Philadelphians saw their monthly water bills jump by about 12%, the second-largest rate hike that year of any large water system in the country. This year, rates went up by nearly another 10%, now pushing a typical monthly bill close to $100, according to the Philadelphia Water Department. But if these recent

Uber-urban South Philadelphia might seem an unlikely place to find the next generation of naturalists, environmentalists and outdoor aficionados. But over the past four years, Adam Forbes, founder and director of the Philadelphia-based nonprofit Discovery Pathways, has done exactly that. After early career stops working with migrants, secondary school students and English language learners, Forbes
