Mutated beta-catenin in bone cells may cause up to 40 percent of acute myeloid leukemia cases. In the cells of healthy subjects (left), beta catenin proteins (red dots) sit along the outer edges of the cell. In approximately 40 percent of AML patients (right), abnormal beta-catenin proteins (red dots) move into the cell interior; in mouse models, this movement sets cancer-causing changes into motion.

For centuries, researchers in fields as disparate as astrophysics and political science have faced the same hurdle before they could win acceptance for their theories—their peers must replicate and verify their results.
A team of Columbia Engineering researchers, led by Mechanical Engineering Professor James Hone and Electrical Engineering Professor Kenneth Shepard, has taken advantage of graphene’s special properties—its mechanical strength and electrical conduction—and created a nano-mechanical system t
