    As the oceans warm in response to climate change, fishing boats in the Mid-Atlantic that focus on only one or two species of fish are traveling more than 250 miles farther north than they did 20 years ago, while others catching a wide diversity of species have not changed fishing location, reported Talia Young, a postdoctoral research associate in ecology and evolutionary biology at Princeton.

  • MERMAIDs reveal secrets from below the ocean floor

    Seismologists use waves generated by earthquakes to scan the interior of our planet, much like doctors image their patients using medical tomography. Earth imaging has helped us track down the deep origins of volcanic islands such as Hawaii, and identify the source zones of deep earthquakes.

  • Sewers could help clean the atmosphere

    Sewage treatment — an unglamorous backbone of urban living — could offer a cost-effective way to combat climate change by flushing greenhouse gases from the atmosphere.

  • Andlinger Center Speaks: U.S. carbon dioxide emissions rise by 3.4 percent

    Carbon dioxide emissions rose in the U.S. by 3.4 percent in 2018, according to preliminary estimates released this week. Increased electricity demand and economic growth are among the contributing factors the report cites. Interestingly, electricity production from coal actually dropped last year.

    Experts Judi Greenwald, Eric Larson and Michael Oppenheimer from Princeton University’s Andlinger Center for Energy and the Environment comment on the news.

  • Researchers track hurricane’s effects on river pollution and beneficial bacteria

    On a rainy Saturday in October, Princeton graduate students Arianna Sherman and Weitao Shuai parked their car by a bridge on a rural road in Hillsborough, North Carolina. In rubber boots, they waded into a muddy stream to begin investigating how farm waste and a giant storm may have disrupted an ecosystem.

  • Treasure in ancient trash: Learning about Japan's history through metals waste

    Thomas Conlan fiddled with a strange, brownish-black rock on his desk. For centuries, people had considered the piece of rubble worthless, but it is priceless to Conlan’s research.

    The lumpy rock is a sample of slag, the material left over after heating ore to extract valuable metals. With researchers from art, engineering and materials science, Conlan is exploring whether these discarded scraps can fill gaps in early Japanese history.

  • Habits and history determine if conservation succeeds or fails

    The ghosts of harvesting past can haunt today's conservation efforts.

    The conservation or overharvesting of a resource such as fish, timber or other wildlife often is determined by past habits and decisions related to that resource, according to a study led by researchers at Rutgers and Princeton universities that examined why conservation succeeds or fails.

  • Houston's urban sprawl increased rainfall, flooding during Hurricane Harvey

    Houston's urban landscape directly contributed to the torrential rainfall and deadly flooding experienced during Hurricane Harvey in August 2017, according to Princeton and University of Iowa researchers. The researchers report in the journal Nature Nov. 15 that Houston's risk for extreme flooding during the hurricane — a category 4 storm that caused an estimated $125 billion in damage and killed 68 people — was 21 times greater due to urbanization. 

  • Human activities are dissolving the seafloor

    With increasing carbon dioxide from human activities, more acidic water is reaching the deep sea, dissolving some calcite-based sediments, say an international team of researchers.
