Emissions that occur over the lifetime of a fossil-fuel-burning electric generator are today routinely assigned to the year of emission ((a), blue blocks). Socolow and Davis present an alternate accounting where the same emissions are instead recorded as committed emissions in the year the generator begins operating (i.e. online year; (a), green blocks). As time passes, it is possible to track the fraction of these committed emissions that have been realized and the fraction that remain co
Researchers from Princeton University and the University of Edinburgh find first evidence that natural selection favors an individual’s tolerance to infection.
Princeton researchers supported  by the Grand Challenges Program have found, overall, water availability has increased in African maize-growing regions, with exceptions in parts of East Africa.
Simon Levin, the George M. Moffett Professor of Biology at Princeton University, was elected a foreign member of the Lombard Institute Academy of Science and Letters.

The Wellcome Trust, a global charitable foundation focused on improving human and animal health, noted Grenfell's more than 30 years of experience in researching the population dynamics of infectious diseases.
Global use of antibiotics is surging according to Princeton University researchers who have conducted a broad assessment of antibiotic consumption around the world.
The study, "Global Trends in Antibiotic Consumption, 2000-2010," found that worldwide antibiotic use has risen a staggering 36 percent over those 10 years, with five countries — Brazil, Russia, India, China and South Africa (BRICS)— responsible for more than three-quarters of that surge, according to study auth
Although scenes of people fleeing from dramatic displays of Mother Nature’s power dominate the news, gradual increases in an area’s overall temperature actually lead more often to permanent population shifts.
Leaders from industry and academia met recently at Princeton University to discuss three big questions surrounding the broad theme of "water": infrastructure, the water/energy nexus, and industrial water.
A five-year study led by Princeton University researchers suggests that certain wild African animals, particularly elephants, could be a boon to human-raised livestock because of their voracious appetite for the toxic and invasive plant Solanum campylacanthum, or the Sodom apple.
Princeton University researchers found that as water freezes it takes on a sort of split personality wherein, at very cold temperatures and above a certain pressure, it may split into two liquid forms.
