out by interdisciplinary research teams, focus on five program areas: health and health care; children and families; aging, chronic conditions and end of life; science and the self; humans and nature. Research projects consist of seminar-style meetings that bring together people with diverse views and expertise to address issues that pose dilemmas and challenges to society. Recent projects include Goals and Practices for Next-Generation Prenatal Genetic Testing; The Last Stage of Life, a planning process to determine how best to meet the new and complex needs of our aging society; Public Deliberation on Gene Editing in the Wild; Actionable Ethics Oversight of Human-Animal Chimera Research; and ongoing work on immigrant health. Hastings Center research strives to frame and explore issues that inform professional practice, public conversation, and policy. The Robert S. Morison Library, located at the center's offices in Garrison, New York, serves as a resource for Hastings' scholars, fellows and visitors. Influence The Hastings Center is recognized as having established bioethics as a field of study. The Hastings Center's 1987 "Guidelines on the Termination of Life-Sustaining Treatment and the Care of the Dying" was foundational in setting the ethical and legal framework for U.S. medical decision-making. It was cited in the 1990 Supreme Court ruling in Cruzan v. Director, Missouri Department of Health, which established patients' constitutional right to refuse life-sustaining treatment and affirmed that surrogates could make decisions for patients lacking that capacity. An updated, expanded edition, The Hastings Center Guidelines for Decisions on Life-Sustaining Treatment and Care Near the End of Life, was published in 2013. Recommendations from The Hastings Center's Undocumented Patients project in partnership with the New York Immigration Coalition informed New York City Mayor Bill de Blasio's announcement in January 2019 that New York City would guarantee comprehensive health care for all New Yorkers, regardless of immigration status. Hastings Center research scholars are frequently called upon for policy advice by committees and agencies at both the federal and state levels. Recent examples include The National Academies of Sciences, Engineering, and Medicine's Gene Drives on the Horizon report, which was produced by a committee that included Hastings Center research scholar Gregory Kaebnick, and the National Academies Physician-Assisted Death workshop, whose planning committee included Hastings research scholar Nancy Berlinger. Notable fellows, past and present Hastings Center fellows are elected for their contributions to informing scholarship or public understanding of the complex ethical issues in health, health
