    In the summer of 2019, a group of Princeton undergraduates embarked on a six-week Global Seminar in central Kenya, studying ecology and conservation as well as filmmaking fundamentals with Princeton faculty and other renowned instructors.

    Their classroom was Mpala, 48,000 acres of privately owned conservation lands managed by the University in partnership with the Smithsonian Institution, the National Museums of Kenya and the Kenya Wildlife Service.

  • Microbe chews through PFAS and other tough contaminants

    In a series of lab tests, a relatively common soil bacterium has demonstrated its ability to break down the difficult-to-remove class of pollutants called PFAS, researchers at Princeton University said.

    The bacterium, Acidimicrobium bacterium A6, removed 60% of PFAS — specifically perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) — in lab vials over 100 days of observation, the researchers reported in an article in the journal Environmental Science and Technology.

  • Innovative tiny laser has potential uses in drug quality control, medical diagnosis, airplane safety

    In a major step toward developing portable scanners that can rapidly measure molecules on the pharmaceutical production line or classify tissue in patients’ skin, a Princeton-led team of researchers has created an imaging system that uses lasers small and efficient enough to fit on a microchip.

    The team demonstrated the system’s resolution by using it to image a U.S. quarter. Fine details like the eagle’s wing feathers, as small as one-fifth of a millimeter wide, were clearly visible.

  • Fewer fish may reach breeding age as climate change skews timing of reproduction, food availability

    Climate change may be depriving juvenile fish of their most crucial early food source by throwing off the synchronization of when microscopic plants known as phytoplankton bloom and when fish hatch, according to Princeton University researchers. The long-term effect on fish reproductivity could mean fewer fish available for human consumption. 

  • New research raises possibility of better anti-obesity drugs

    Friday, Jun 28, 2019
    by Princeton University

    Effective weight-loss strategies call for eating less food, burning more calories — or ideally, both. But for the more than 90 million Americans who suffer from obesity, a disease that contributes to conditions ranging from heart disease to cancer, behavioral change is hard to accomplish or not effective enough, which is why scientists have long sought drugs that would help people shed pounds. Yet effective, long-lasting treatments have thus far eluded them.
