    Plastic pollution is ubiquitous today, with microplastic particles from disposable goods found in natural environments throughout the globe, including Antarctica. But how those particles move through and accumulate in the environment is poorly understood. Now a Princeton University study has revealed the mechanism by which microplastics, like Styrofoam, and particulate pollutants are carried long distances through soil and other porous media, with implications for preventing the spread and accumulation of contaminants in food and water sources.

  • Cava brings materials expertise to Quantum Consortium

    Most scientists start conversations about quantum computing with the warning that it’s a really weird field – random, unforgivingly complex, indifferent to the laws of physics as we know them. Even Albert Einstein and Niels Bohr were drawn into a battle 90 years ago over the principles that underlie quantum theory, with Einstein famously saying during that row, “God does not play dice with the universe.”

  • Clifford Brangwynne to lead Princeton Bioengineering Initiative

    by Steven Schultz, Office of Engineering Communications

    Clifford Brangwynne, professor of chemical and biological engineering, has been appointed the inaugural director of the Princeton Bioengineering Initiative. This initiative will support and expand the bioengineering activities already underway at the University, and ignite new directions in research, education and innovation at the intersection of the life sciences and engineering.

  • Princeton’s “Dinky” train helps nuclear arms control researchers

    With a new crisis seeming to dominate every news cycle, for now the threat of nuclear war has faded into the background of public attention. Yet the arsenals themselves have not vanished, and researchers at Princeton University are working to develop new methods to verify compliance with arms limitations treaties to help reduce the possible risk of a nuclear exchange.

  • A new spin on atoms gives scientists a closer look at quantum weirdness

    by Scott Lyon, School of Engineering

    When atoms get extremely close, they develop intriguing interactions that could be harnessed to create new generations of computing and other technologies. These interactions in the realm of quantum physics have proven difficult to study experimentally due the basic limitations of optical microscopes.

  • Robert Prud’homme named first recipient of Princeton’s Dean for Research Award for Distinguished Innovation

    Robert Prud’homme, professor of chemical and biological engineering at Princeton University, has been selected to receive the inaugural Dean for Research Award for Distinguished Innovation for the invention of flash nanoprecipitation, a method for creating nanoparticles that promises to improve the delivery of drugs throughout the body.

  • How exactly do we spread droplets as we talk? Engineers found out.

    For the first time, researchers have directly visualized how speaking produces and expels droplets of saliva into the air. The smallest droplets can be inhaled by other people and are a primary way that respiratory infections like COVID-19 spread from person to person.

  • Novel drug could be a powerful weapon in the fight against malaria and toxoplasmosis

    Tuesday, Sep 15, 2020
    by Adam Hadhazy for the Office of Engineering Communications

    Princeton researchers are making key contributions toward developing a promising new treatment for the widespread and devastating diseases toxoplasmosis and malaria.

    The Princeton scientists specialize in preparing the drug compound into a medicine that is both safe and effective for humans and able to reach its intended sites of action in the body in sufficient doses.
