A hot area of gerontology is in life extension research and technology, where researchers are working to slow, prevent, and reverse aging. Approaches include curing age-related diseases and slowing down the underlying processes of aging. These researchers are working with those in molecular biology, biotechnology nanoscience, and immunology to develop ways to extend life. This includes replacing diseased or dying organs through xenotransplantation or artificial organs, stem cell technology, and molecular repair. Currently, the most successful method of life extension appears to be caloric restriction, but this has only been observed to be successful in lower mammals such as mice and rats.
Other researchers are focusing on more conventional topics in gerontology. This includes developing new policies for hospices, nursing homes, and other venues where the elderly live with caregivers. New policies always undergoing scrutiny include ethical considerations, staffing levels, medication, and quality-of-life issues. See the articles on public health, nursing, palliative care, and social work for more information.
