Mayo Clinic Researchers Extend Lifespan by as Much as 35 Percent in Mice

Researchers at Mayo Clinic have shown that senescent cells – cells that no longer divide and accumulate with age – negatively impact health and shorten lifespan by as much as 35 percent in normal mice. The results, which appear today in Nature, demonstrate that clearance of senescent cells delays tumor formation, preserves tissue and organ function, and extends lifespan without observed adverse effects.

New Mathematical Model Illustrates Link Between Energy Use and Aging

Why does a Great Dane have a shorter lifespan than a pug? The answer lies in a complex relationship between energy usage and lifespan. That relationship is quickly being unraveled through the use of numerical modeling by a researcher at Missouri S&T.

Study Shows Zinc Supplement Boosted Serum Zinc Levels and Immunity in Older Adults

A new study finds that providing zinc supplements to older adults in nursing homes increased their serum zinc levels and improved their immune response, providing potential protection against infection. The research group’s previous work found that nursing home residents had low zinc levels.

Cancer Riddle, Solved

Using real-time recording of cellular movement, biologists at the University of Iowa have discovered how tumors form. Cancer cells reach out and grab other cells, and as little as five percent cancerous cells are needed for tumor formation. Findings could lead to more precise cancer testing.

Work Schedule Is Top Barrier to Staying Healthy, According to First-Ever Mayo Clinic National Health Check-Up®

“The Mayo Clinic National Health Check-Up takes a pulse on Americans’ health opinions and behaviors, from barriers to getting healthy to perceptions of aging, to help identify opportunities to educate and empower people to improve their health,” says John T. Wald, M.D., Medical Director for Public Affairs at Mayo Clinic. “In this first survey, we’re also looking at ‘health by the decades’ to uncover differences as we age.”

International Study Reveals New Genetic Clues to Age-Related Macular Degeneration

NEI_Eye_Infographic_FINAL_AMD_PRINT.jpg

An international study of about 43,000 people has significantly expanded the number of genetic factors known to play a role in age-related macular degeneration (AMD), a leading cause of vision loss among people age 50 and older. Supported by the National Eye Institute (NEI), part of the National Institutes of Health, the findings may help improve our understanding of the biological processes that lead to AMD and identify new therapeutic targets for potential drug development.
