    For Thomas Pisano, the motivation to become a doctor and scientist was personal. A skiing accident left his legs paralyzed, fueling his aspiration to become a physician and biomedical researcher who could both conduct scientific investigations and apply that knowledge to saving lives in the clinic.

  • Habits and history determine if conservation succeeds or fails

    The ghosts of harvesting past can haunt today's conservation efforts.

    The conservation or overharvesting of a resource such as fish, timber or other wildlife often is determined by past habits and decisions related to that resource, according to a study led by researchers at Rutgers and Princeton universities that examined why conservation succeeds or fails.

  • Red wolf DNA found in mysterious Texas canines

    Though red wolves were declared extinct in the wild by 1980, a team of biologists has found their DNA in a group of canines living on Galveston Island off the coast of Texas.

  • Hummingbirds dive to dazzle females in a highly synchronized display

    When it comes to flirting, animals know how to put on a show. In the bird world, males often go to great lengths to attract female attention, like peacocks shaking their tail feathers and manakins performing complex dance moves. These behaviors often stimulate multiple senses, making them hard for biologists to quantify.

  • Biologists turn eavesdropping viruses into bacterial assassins

    Princeton molecular biologist Bonnie Bassler and graduate student Justin Silpe have identified a virus, VP882, that can listen in on bacterial conversations — and then, in a twist like something out of a spy novel, they found a way to use that to make it attack bacterial diseases like E. coli and cholera.

  • Researchers find a way to peel slimy biofilms like old stickers

    Slimy, hard-to-clean bacterial mats called biofilms cause problems ranging from medical infections to clogged drains and fouled industrial equipment. Now, researchers at Princeton have found a way to cleanly and completely peel off these notorious sludges.

  • New tools illuminate mechanisms behind overlooked cellular components’ critical roles

    Creating new tools that harness light to probe the mysteries of cellular behavior, Princeton researchers have made discoveries about the formation of cellular components called membraneless organelles and the key role these organelles play in cells.

    In two papers published Nov. 29 in the journal Cell, researchers from multiple Princeton departments report on the conditions that lead to the formation of membraneless organelles and the impact that the formation has on cellular DNA.

  • Princeton geneticist solves long-standing finch beak mystery

    by Liz Fuller-Wright, Office of Communications

    Bridgett vonHoldt is best known for her work with dogs and wolves, so she was surprised when a bird biologist pulled her aside and said, “I really think you can help me solve this problem.” So she turned to a mystery he’d been wrestling with for more than 20 years.
