Construction began four years ago on Mt. Sinai New York's new 550,000sf Hess Center for Science and Medicine on E. 102nd St., between Madison and Fifth Avenues in East Harlem. Originally due for completion this fall, the new opening date has been pushed into spring of 2013. The 13-storey building is a major advance in the medical institute's larger plan of integrating its clinical and research areas through a strong translational medicine program. Basic research facilities will include wet and dry bench labs, animal facilities, and computer-supported research spaces. There will be lounges, meeting and education rooms, and other open, interactive spaces to encourage collaboration through daily contact. The half million square feet will add to, not replace, Mount Sinai School of Medicine's overall facility space. They have already begun recruiting and hiring new faculty researchers.
