    Princeton University will undergo one of the most extensive building programs in its history over the next decade — adding some 3 million square feet in new construction to house more students, expand research facilities, and replace aging buildings and infrastructure.

  • Is Lake Carnegie showing a climate trend?

    The heavy snowfalls and frigid days of this past winter in New Jersey let Princeton sophomore Grace Liu finally experience the Northeastern winter she’d only imagined growing up in her Florida hometown of palm trees and sandy beaches.

  • Despite sea-level rise risks, migration to some threatened coastal areas may increase

    In coming decades as coastal communities around the world are expected to encounter sea-level rise, the general expectation has been that people’s migration toward the coast will slow or reverse in many places.

    However, new research co-authored by Princeton University scholars shows that migration to the coast could actually accelerate in some places despite sea-level change, contradicting current assumptions.

  • Adherence to health precautions, not climate, the biggest factor driving wintertime COVID-19 outbreaks

    Wintertime outbreaks of COVID-19 have been largely driven by whether people adhere to control measures such as mask wearing and social distancing, according to a study published Feb. 8 in Nature Communications by Princeton University researchers. Climate and population immunity are playing smaller roles during the current pandemic phase of the virus, the researchers found.

  • Carbon-chomping soil bacteria may pose hidden climate risk

    Much of the earth’s carbon is trapped in soil, and scientists have assumed that potential climate-warming compounds would safely stay there for centuries. But new research from Princeton University shows that carbon molecules can potentially escape the soil much faster than previously thought. The findings suggest a key role for some types of soil bacteria, which can produce enzymes that break down large carbon-based molecules and allow carbon dioxide to escape into the air.

  • Mange in Yellowstone wolves reveals insights into human scabies and conservation biology

    Before wolves were reintroduced to Yellowstone National Park in the mid-1990s, they were vaccinated for common diseases and treated for any parasite infections they already carried. As a result, the first few generations of wolves were relatively disease-free, but over the years, various diseases have found their way into the population. 

  • Plastic pollution is everywhere. study reveals how it travels

    Plastic pollution is ubiquitous today, with microplastic particles from disposable goods found in natural environments throughout the globe, including Antarctica. But how those particles move through and accumulate in the environment is poorly understood. Now a Princeton University study has revealed the mechanism by which microplastics, like Styrofoam, and particulate pollutants are carried long distances through soil and other porous media, with implications for preventing the spread and accumulation of contaminants in food and water sources.
