Does aging vary across different species? How much?
University Professor Caleb Finch discusses the wide spectrum of aging rates in the animal kingdom and what it could mean for humans.
USC scientists identify genetic variants linked to mobility changes in aging
Study suggests changes in strength and mobility may depend on genetic variations in a critical mitochondrial enzyme and provides a new biomarker linked to age-related muscle health.
‘Longevity diet’ characteristics: What (and when) to eat for a long life
USC Professor Valter Longo and a colleague describe the “longevity diet,” a way of eating that considers food composition and calorie intake as well as the length and frequency of fasting.
Keeping the planet healthy could help people have healthier lifespans, too
EARTH WEEK: Experts at the USC Leonard Davis School of Gerontology share why caring for the environment can help people as they age.
Winning collaboration makes homes safer for aging Angelenos
The USC Leonard Davis School of Gerontology joins forces with Rebuilding Together to help those in need and teach professionals how to help older adults age safely at home.
To reduce COVID-19 risk, individual distancing makes a difference
Even when faced with risks such as living in an area with high infection rates, people who avoid large gatherings and other risky behaviors are less likely to be diagnosed with COVID-19, USC researchers say.
How does air pollution influence Alzheimer’s risk?
Studying neural stem cells could shed light on how environmental aspects interact with genetic risk factors for dementia, says University Professor Caleb Finch.
Research into small protein sheds light on battling autoimmune disease
The protein appears to have a big role in regulating the immune system, USC’s David Lee says.
COVID-19 brought bigger drop in average American lifespan than previously thought
The pandemic reduced overall U.S. life expectancy by over 1.3 years, USC research has found, with the effects on Black and Latino populations 2 to 3 times those for the white population.
Beyond genes and environment, random variations play important role in longevity
The USC-UCLA paper introducing a new conceptual model notes that only about 10 to 35% of longevity can be traced to genes inherited from our parents.
Phoebe S. Liebig, 87, celebrated gerontology educator and policy expert on aging
Along with her work at the USC Leonard Davis School of Gerontology, Liebig spent two years as a senior economics policy analyst for the AARP Public Policy Institute.
Hormones in the brain may explain how exercise improves metabolism
USC researchers are studying the function of a mitochondrial hormone in the brain, and their findings could lead to drugs that provide the health benefits of exercise to disabled individuals.
‘Exercise protein’ shows potential to restore physical fitness and performance
Data from hormone research reveal new target for reversing age-related decline, according to USC study.
New findings help explain how COVID-19 overpowers the immune system
USC research offers possible explanations as to why older adults and people with metabolic dysfunction have more severe responses to the coronavirus than other individuals.
Beyond changing DNA, mutagens also cause errors in gene transcription
The USC research discovery opens new avenues of research for diseases like Alzheimer’s and Parkinson’s.
To better understand aging, look at both biological and social factors
Incorporating socioeconomic status and childhood adversity alongside biological mechanisms is critical for improving aging research, a USC study finds.
What history tells us about the long-term effects of a pandemic
USC research showed that people born during or just after the 1918 flu pandemic faced increased heart disease risk more than 60 years later. The legacy of COVID-19 could be worse.
Studying tiny worms could unlock new insights into human life
Two USC studies on diet and sperm quality in C. elegans illustrate how changes in the worm species could lay the groundwork for further research on human lifespan and reproduction.
Predicting the long-term effects of prenatal COVID-19 exposure
Infants born to mothers infected by the virus that causes COVID-19 could suffer from developmental difficulties and accelerated aging down the line, USC research finds.
How social factors impact our genes — and our health
A $2.9 million grant to Eileen Crimmins of the USC Leonard Davis School of Gerontology supports multination research on how life circumstances influence gene expression and affect health.
What it’s like to intern — and live — in a retirement community during COVID-19
Nelson Rubio Argueta’s internship couldn’t go virtual during the pandemic; he was living and working in Kingsley Manor Retirement Community in L.A. The gerontology student discusses his unique experience.
Taking precautions to prevent COVID-19 linked to the media you consume
People who trust left-leaning news sources are more likely to engage in key virus-mitigating behaviors, according to research from faculty and PhD students at USC Leonard Davis.

Backed by the National Institute on Aging, the $4.4 million renewal will support researchers working to improve population health.
Dementia-related deaths in the U.S. may be higher than reported
Death certificate data appear to underestimate the true mortality burden of dementia, Alzheimer’s disease and other cognitive impairment, according to a USC-led study.
