How one gene in a tiny fish may alter an aquatic ecosystem
Linking genomics to evolution to ecology, the work takes an unusual approach to reveal broad implications of how species adapt to their local environment.
Eight Penn faculty share their favorite general interest books about science.
Keeping campus trees—all 6,800 of them—healthy and vibrant
Caring for the trees on Penn’s campus—an official arboretum since last year—is no small undertaking. Staff from Facilities and Real Estate Services and the Morris Arboretum lead the way in ensuring that the University’s trees remain safe, vibrant, diverse, and beautiful.
Tracing the evolutionary origins of fish to shallow ocean waters
Coral reefs are envisioned as the seats of great biodiversity, but they may not be where all that diversity got its start. In a new study in Science, paleobiologist Lauren Sallan and colleagues reveal that the earliest fish may have diversified in shallower waters near shore.
Analyzing roadside dust to identify potential health concerns
Reto Gieré is working with collaborators across the world to identify an overlooked but significant factor in traffic-related air pollution: Tiny bits of tires, brake pads, and road materials that become suspended in the air when vehicles pass over.
Floating art installation brings Schuylkill River history to life

Navigating urban waters, with an interdisciplinary approach
With independent research projects and immersive experiences on and near Philadelphia’s waterways, summer fellows with the Penn Program in the Environmental Humanities are collaborating to develop new ways of learning and sharing knowledge.
Five things to know about the new EPA acting administrator
Following Scott Pruitt’s resignation, will Andrew Wheeler stay the course or chart a new path for the agency, and what does it mean for the environment?
Philly as lab, classroom, and collaborator
Philadelphia’s rich history and forward momentum make it ripe for scientific inquiry for a number of Penn schools and departments, from urban and population studies to medicine and anthropology.
Frigid polar oceans, not coral reefs, are hot spots for formations of fish species
Tropical waters contain a dazzling diversity of fish species compared to colder ocean areas. Yet a new study paradoxically indicates that the colder waters are home to the highest species formation rates.

PGW plan for liquified natural gas facility in Southwest Philadelphia clears hurdle
Christina Simeone of the Kleinman Center for Energy Policy discussed the possible environmental impact of the creation of a new liquified natural gas (LNG) facility in Southwest Philadelphia. “The environmental benefit will happen if LNG displaces diesel or fuel oil,” she said. “But it’s just not clear until there’s a client base who is going to be the end user of this gas.”

Philly affirms commitment to slashing emissions as study shows global increase
Christine Simeone of the Kleinman Center for Energy Policy spoke about cities and states’ continued efforts in the fight against climate change. “In the absence of a national strategy, the state and local strategies actually become much more important,” said Simeone.
