Princeton researchers receive $2.5 million to advance the science of urban food sustainability
November 06, 2019
Princeton University researchers have received a $2.5 million federal grant to lead an interdisciplinary effort with academic, city government and nonprofit partners that will develop a scientific process for establishing urban food systems that are less wasteful and environmentally detrimental. The grant will be administered by the Princeton Environmental Institute (PEI).
Method promises advances in 3D printing, manufacturing and biomedical applications
October 31, 2019
In a development offering great promise for additive manufacturing, Princeton University researchers have created a method to precisely create droplets using a jet of liquid. The technique allows manufacturers to quickly generate drops of material, finely control their size and locate them within a 3D space.
Why are big storms bringing so much more rain? Warming, yes, but also winds
October 29, 2019
For three hurricane seasons in a row, storms with record-breaking rainfall have caused catastrophic flooding in the southern United States. A new analysis by Princeton researchers explains why this trend is likely to continue with global warming: Both the higher moisture content of warmer air and storms’ increasing wind speeds conspire to produce wetter storms.
Shrinking grains expand understanding of self-healing materials
October 22, 2019
Cracks in the desert floor appear random to the untrained eye, even beautifully so, but those patterns of dried clay turn out to be predictable—and useful in designing advanced materials.
Investigating 'fourth state of matter' for renewable energy
October 21, 2019
A team from Princeton University and Ohio State University has been awarded a five-year, $3-million grant from the U.S. Department of Energy to advance research on low-temperature plasmas with the broader goal of improving energy efficiency and renewable energy technologies.
Graduate students help meet data centers' voracious appetite for power
October 18, 2019
A Princeton team's innovation in efficiency could mark a major shift for data centers, which face exponential growth over the coming decade.
Protecting smart machines from smart attacks
October 10, 2019
Machines' ability to learn by processing data gleaned from sensors underlies automated vehicles, medical devices and a host of other emerging technologies. But that learning ability leaves systems vulnerable to hackers in unexpected ways, researchers at Princeton University have found.
Avoiding dangers of AI in warfare requires responsible U.S. leadership among international community, general says
October 03, 2019
International agreements and coordinated diplomatic pressures will be essential in avoiding indiscriminate use of artificial intelligence in lethal military conflicts, retired Gen. John R. Allen told an audience at Princeton University on Wednesday, Oct. 2.
Engineering faculty take on 'Grand Challenges' in the environment
October 02, 2019
The Princeton Environmental Institute (PEI) gave awards to 13 projects, including five within the School of Engineering and Applied Science, as part of its Water and the Environment Grand Challenge program. Totaling $1.01 million, the newly awarded undertakings explore an array of topics in multiple disciplines, from wastewater emissions and the role of climate change in spreading plant diseases, to nitrogen-hungry bacteria and a plan to capture carbon dioxide while mitigating mining runoff. The projects run from 2019 to 2021.
The Moving City
October 01, 2019
Transportation into, out of, and within cities has been one of the key enablers of urban growth. As cities grow larger and more complex, ensuring that people, goods, and information flow smoothly will become all the more important.
