- A rare mutation that causes growth hormone receptor deficiency (leading to 40% life extension in mice) is found in just 400 to 500 people worldwide. They have dwarfism, but lower risk of age-related diseases, cancer, diabetes and heart disease, and healthier brains and better cognition and memory. https://gero.usc.edu/2024/04/26/people-with-rare-longevity-mutation-may-also-be-protected-from-cardiovascular-disease/ 24 comments science
- Fasting-Like Diet Lowers Risk Factors for Disease, Reduces Biological Age in Humans. First study to show that a food-based intervention that does not require chronic dietary or other lifestyle changes can make people biologically younger, based on both changes in risk factors for aging and disease https://gero.usc.edu/2024/02/20/fasting-mimicking-diet-biological-age/ 65 comments science
- New study challenges previous ideas regarding Alzheimer’s disease. Research found the increase in soluble Aβ may be a general aging-related change in the brain not specific to Alzheimer’s, while higher levels of fibrillary amyloid appear to be a better indicator of poorer brain health. https://gero.usc.edu/2023/01/05/new-study-challenges-previous-ideas-regarding-alzheimers-disease/ 13 comments science

- An updated analysis of American COVID-19 deaths throughout 2021 highlights a continued drop in life expectancy as well as persistent disparities by race and ethnicity. Life expectancy at birth decreased 2.2 years between 2019 and 2021, with the decrease for 2021 being 0.6 years larger than 2020. https://gero.usc.edu/2022/09/01/covid-19-u-s-life-expectancy-continued-to-decrease-in-2021-study-finds/ 7 comments science

- Study finds mitochondrial gene that protects against dementia and other diseases of aging. Research uncovered an unknown genetic risk factor for Alzheimer’s and related dementias. Findings provide insights on how these conditions, and other diseases of aging, might one day be treated and prevented. http://gero.usc.edu/2018/09/21/new-research-reveals-a-mitochondria-gene-that-protects-against-dementia/ 7 comments science
