Everyone knows that exercise is good for you, but what type of training helps most, especially when you’re older - say over 65? A Mayo Clinic study says it’s high-intensity aerobic exercise, which can reverse some cellular aspects of aging. The findings appear in Cell Metabolism.
Research into retinal regeneration in zebrafish has identified a signal that appears to trigger the self-repair process, raising the possibility that human retinas can also be induced to regenerate, naturally repairing damage caused by degenerative retinal diseases and injury, including age-related macular degeneration and retinitis pigmentosa.
Mayo Clinic researchers have uncovered three new agents to add to the emerging repertoire of drugs that aim to delay the onset of aging by targeting senescent cells – cells that contribute to frailty and other age-related conditions.
Healthy lifestyle adherence among retired, late middle-aged adults may be more challenging than originally thought.
Age-related macular degeneration (AMD), the leading cause of vision loss among older adults in the United States, is often associated with psychological stress. A simple stress rating scale (the Perceived Stress Scale) is a valid and useful way to evaluate the connection between stress and progressive vision loss from AMD, according to a study in the March issue of Optometry and Vision Science, the official journal of the American Academy of Optometry. The journal is published by Wolters Kluwer.

As people get older so do the hematopoietic stem cells (HSCs) that form their blood, creating an increased risk for compromised immunity and certain blood cancers. Now researchers are reporting in the scientific journal EMBO that the bone marrow niche where HSC’s form also ages, contributing to the problem. In a study published March 2, scientists in Germany and the United States propose rejuvenating the bone marrow niche where HSCs are created.
Images of our faces exist in numerous important databases - driver's license, passport, law enforcement, employment - all to accurately identify us. But can these images continue to identify us as we age? Michigan State University biometrics expert Anil Jain and team set out to investigate what extent facial aging affects the performance of automatic facial recognition systems and what implications it could have on successfully identifying criminals or determining when identification documents need to be renewed.

Cedars-Sinai neuroscientists have uncovered processes involved in how the human brain creates and maintains short-term memories. This study is the first clear demonstration of precisely how human brain cells work to create and recall short-term memories. Confirmation of this process and the specific brain regions involved is a critical step in developing meaningful treatments for memory disorders that affect millions of Americans.
Adult stem cells collected directly from human fat are more stable than other cells – such as fibroblasts from the skin – and have the potential for use in anti-aging treatments, according to researchers from the Perelman School of Medicine at the University of Pennsylvania. They made the discovery after developing a new model to study chronological aging of these cells.
Biologists have known for decades that enduring a short period of mild stress makes simple organisms and human cells better able to survive additional stress later in life. Now, scientists at Sanford Burnham Prebys Medical Discovery Institute (SBP) have found that a cellular process called autophagy is critically involved in providing the benefits of temporary stress. The study, published today in Nature Communications, creates new avenues to pursue treatments for neurological disorders such as Huntington’s disease.
Rutgers scientists say neurodegenerative diseases like Alzheimer’s and Parkinson’s may be linked to defective brain cells disposing toxic proteins that make neighboring cells sick. In a study published in Nature, Monica Driscoll, distinguished professor of molecular biology and biochemistry, School of Arts and Sciences, and her team, found that while healthy neurons should be able to sort out and rid brain cells of toxic proteins and damaged cell structures without causing problems, laboratory findings indicate that it does not always occur.

As the number of grandparents caring for grandchildren full-time continues to swell, so do the stress-induced health risks associated with such a demanding responsibility. Now, a four-year, $2 million grant from the National Institutes of Health will allow researchers at Case Western Reserve University’s Frances Payne Bolton School of Nursing to refine and test a new approach to help grandmothers manage the stresses of the this new role—and hopefully reduce the emotional and physical fallout that often results.
PHOENIX – Mayo Clinic researchers have found that engaging in mentally stimulating activities, even late in life, may protect against new-onset mild cognitive impairment, which is the intermediate stage between normal cognitive aging and dementia. The study found that cognitively normal people 70 or older who engaged in computer use, craft activities, social activities and playing games had a decreased risk of developing mild cognitive impairment. The results are published in the Jan. 30 edition of JAMA Neurology.
