    Belying their slimy natures, the sticky patches of bacteria called biofilms often form intricate, starburst-like patterns as they grow. Now, researchers at Princeton University have combined expertise in molecular biology, mechanical engineering and mathematical modeling to unravel the physical processes underlying these curious crinkles.

    As COVID-19 spreads worldwide, leaders are relying on mathematical models to make public health and economic decisions.

    A new model developed by Princeton and Carnegie Mellon researchers improves tracking of epidemics by accounting for mutations in diseases. Now, the researchers are working to apply their model to allow leaders to evaluate the effects of countermeasures to epidemics before they deploy them.

  • Quantum computing: Opening new realms of possibilities

    Tuesday, Jan 21, 2020
    by Tom Garlinghouse for the Office of the Dean for Research

    Hidden beneath our everyday world — on the infinitesimal scale of atomic and subatomic particles — is a strange and elusive realm. It is a Lewis Carroll-like place where ghostly particles pop in and out of existence, swirling electrons occupy two positions at once, and objects possess dual natures — they can be both waves and particles simultaneously.
