Adherence to health precautions, not climate, the biggest factor driving wintertime COVID-19 outbreaks
Feb. 9, 2021
Written by Morgan Kelly, High Meadows Environmental Institute

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…

Carbon-chomping soil bacteria may pose hidden climate risk
Jan. 28, 2021
Written by Molly Sharlach, Office of Engineering Communications

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…

Mange in Yellowstone wolves reveals insights into human scabies and conservation biology
Jan. 25, 2021
Written by Liana Wait, Department of Ecology and Evolutionary 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. 

Big but affordable effort needed for America to reach net-zero emissions by 2050, Princeton study shows

Plastic pollution is everywhere. study reveals how it travels
Nov. 30, 2020
Written by Molly Seltzer, Andlinger Center for Energy and the Environment

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…

People in developing countries eat less wild game as they migrate from rural to urban areas
Nov. 16, 2020
Written by B. Rose Huber, Princeton School of Public and International Affairs

People around the world, especially in developing countries in Africa, Asia and South America, consume wild game, or bushmeat, whether out of necessity, as a matter of taste preference, or, in the case of particularly desirable wildlife species, to connote a certain social status. Bushmeat consumption, however, has devasted the populations of…

Princeton University has established an endowed fund with a gift from Currie C. and Thomas A. Barron that will significantly increase support for environmental research related to…

Large, delayed outbreaks of endemic diseases possible following COVID-19 controls
Nov. 9, 2020
Written by Morgan Kelly, High Meadows Environmental Institute

Measures to reduce the spread of COVID-19 through non-pharmaceutical interventions (NPIs) such as mask wearing and social distancing are a key tool in combatting the impact of the ongoing coronavirus pandemic. These actions also have greatly reduced incidence of many other diseases, including influenza and respiratory syncytial virus (RSV).
