Orange is the New Green: How Orange Peels Revived a Costa Rican Forest

A team led by Princeton University researchers — including David Wilcove, a professor of ecology and evolutionary biology and public affairs and the Princeton Environmental Institute — found that a barren pasture in a Costa Rican national park became a lush forest 16 years after an orange juice company unloaded 1,000 truckloads of orange peels and orange pulp onto it. The researchers report in the journal Restoration Ecology a 176 percent increase in aboveground biomass within the 3-hectare (7-acre) area studied, which demonstrates the power of agricultural waste to potentially regenerate forests and mitigate carbon at low cost. The research was supported by a 2015 Walbridge Fund Graduate Award from the Princeton Environmental Institute.

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

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.
