An immune signaling pathway for control of Yellow Fever Virus infection

Publish Date: 
Tuesday, August 15, 2017 - 1:15pm

Princeton University researchers have uncovered a critical role for a new immune signaling pathway in controlling infection by the flavivirus Yellow Fever Virus (YFV), according to a paper published Aug. 15 in the journal mBio. The research stemmed from a 2015 Grand Health Challenges grant from the Princeton Environmental Institute.

Projected precipitation increases are bad news for water quality

Publish Date: 
Tuesday, August 1, 2017 - 12:45pm

Researchers from Princeton University and elsewhere have found that increased precipitation due to climate change could substantially overload waterways in the United States with excess nitrogen, especially in the Midwest and Northeast. They reported July 28 in the journal Science that greater nitrogen pollution would likely worsen eutrophication, a process by which waterways become overloaded with nutrients and starved of oxygen.

Analysis shows carbon-slashing promise of new biofuel technology

Finding an alternative vehicle fuel poses a difficult challenge: it has to be relatively cheap and able to reduce carbon emissions without using up valuable crop land or trees from forests.

Now, researchers at Princeton’s Andlinger Center for Energy and the Environment say one possible solution might be all around us. In a recent paper, the researchers evaluated a method that creates fuel from wood residues, sawdust and branches. The method, called catalytic hydropyrolysis, could use the refining and distribution systems now used for gasoline to create a fuel that would work in modern engines.

Peter Grant, the Class of 1877 Professor of Zoology, Emeritus, and professor of ecology and evolutionary biology, emeritus, and B. Rosemary Grant, senior research biologist, emeritus, ecology and evolutionary biology, have been named recipients of the Royal Medal in Biology.

New model projects an increase in dust storms in the US

Could the storms that once engulfed the Great Plains in clouds of black dust in the 1930’s once again wreak havoc in the U.S.? A new statistical model developed by researchers at Princeton University and the National Oceanic and Atmospheric Administration (NOAA)’s Geophysical Fluid Dynamics Laboratory (GFDL) predicts that climate change will amplify dust activity in parts of the U.S. in the latter half of the 21st century, which may lead to the increased frequency of spectacular dust storms that have far-reaching impacts on public health and infrastructure.

New PEI director Michael Celia plans to build on Institute's strengths, expand reach

Publish Date: 
Monday, July 10, 2017 - 12:30pm

Michael Celia, the Theodora Shelton Pitney Professor of Environmental Studies and professor of civil and environmental engineering, has been named director of the Princeton Environmental Institute effective July 1. Celia, who has been involved in PEI's research, teaching programs and governance for many years, succeeds François Morel, the Albert G. Blanke, Jr., Professor of Geosciences and professor of geosciences and the Princeton Environmental Institute, who had served as director since 2014.

Climate change to damage U.S. economy, increase inequality

Publish Date: 
Thursday, June 29, 2017 - 2:00pm

Unmitigated climate change could make the United States poorer and more unequal, according to a study in the journal Science that includes PEI researchers. The poorest third of counties could sustain economic damage costing as much as 20 percent of their income by the end of the century if warming proceeds unabated. States in the South and lower Midwest, which tend to be poor and hot already, will lose the most, with economic opportunity traveling northward and westward. Colder and richer counties along the northern border and in the Rockies could benefit the most as health, agriculture and energy costs are projected to improve.

Hatching a new hypothesis about egg shape diversity

Publish Date: 
Thursday, June 22, 2017 - 2:45pm

The research of Mary Caswell Stoddard, a Princeton University assistant professor of ecology and evolutionary biology and PEI-affiliated faculty, suggests that the shape of an egg for a bird of a given species may be driven in part by features of a bird’s physiology related to its capability for flight.

Rising sea levels will boost moderate floods in some areas, severe floods in others

Publish Date: 
Thursday, June 8, 2017 - 3:00pm

A new study by researchers at Princeton and Rutgers universities found that sea-level rise will boost the occurrence of moderate flooding in cities along the southeastern coast, while areas that have little history of severe flooding are likely to experience a greater uptick in the number of severe, or even historically unprecedented, floods.
