• In world's first genetically engineered marsupials, scientists get a fresh window into human biology

    When the pile of opossums arrived at John VandeBerg's lab from the Smithsonian's National Zoo in 1978, the geneticist had an ambitious plan for the soft-eyed, hamster-sized animals. He wanted to domesticate them to live in a lab anywhere on the planet. Mice were well and good, but imagine what biomedical insights might be lurking inside marsupials, he thought. Their young, rather than being encased inside a uterus, develop attached to a nipple in a pouch or on a belly where they're much easier to observe.
    VandeBerg succeeded, and today manages the largest Monodelphis domestica colony in...
