Legos may seem like an unlikely foundation for scientific research, but the building blocks have been a part of Ozgur Sahin’s work since he made a mechanical adding device with them when he was 11.

The Vilcek Foundation named Thomas M. Jessell as the winner of the 2014 Vilcek Prize in Biomedical Science. Awarded annually, the prizes honor the contributions of immigrants to the American arts and sciences, and include $100,000 cash awards. Dr.

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.

Acute myeloid leukemia (AML) is a blood cancer, but for many patients the cancer may originate from an unusual source: a mutation in their bone cells.

Sonya Dyhrman’s interest in marine biology began when she was a child, exploring tidal pools with her grandfather on the coast near her Tacoma.

In recent years, human interactions with intelligent machines and software have become increasingly commonplace.

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.

The examination of mental disorders would seem to be the almost exclusive domain of psychiatrists and psychologists, not humanities scholars. Yet William V. Harris, the William R.

For the first time, scientists have succeeded in transforming human stem cells into functional lung and airway cells.

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
