  • Researchers apply computing power to track the spread of cancer

    Princeton researchers have developed a new computational method that increases the ability to track the spread of cancer cells from one part of the body to another.

    This migration of cells can lead to metastatic disease, which causes about 90 percent of cancer deaths from solid tumors — masses of cells that grow in organs such as the breast, prostate or colon. Understanding the drivers of metastasis could lead to new treatments aimed at blocking the process of cancer spreading through the body.

  • Timing is key for bacteria surviving antibiotics

    For bacteria facing a dose of antibiotics, timing might be the key to evading destruction. In a series of experiments, Princeton researchers found that cells that repaired DNA damaged by antibiotics before resuming growth had a much better chance of surviving treatment.

    When antibiotics hit a population of bacteria, often a small fraction of “persister” cells survive to pose a threat of recurrent infection. Unlike bacteria with genetic resistance to antibiotics, evidence suggests that persisters stay alive in part by stalling cellular processes targeted by the drugs.

  • Petry finds missing ingredient to spark the fireworks of life

    Most people can name at least a few bones of the human body, but not many know about the cytoskeleton within our cells, let alone the “microtubules” that give it its shape. Now, a group of Princeton researchers has resolved a long-standing controversy by identifying exactly how the body creates these micron-sized filaments.

  • Princeton Research Day puts spotlight on innovative work across University

    Monday, May 14, 2018
    by Princeton University

    Spend the day — or an hour — at Princeton Research Day, and you get an eclectic tour of research at Princeton University shared through presentations designed to make cutting-edge work accessible to the general public.

    For Sarah-Jane Leslie, dean of the Graduate School and the Class of 1943 Professor of Philosophy, that tour included learning how engineers can learn lessons from plants; about new techniques to fight disease; and about novel ways to address the world’s energy crisis.
