By knowing that AMPK is vital for maintaining muscle mass with aging, researchers can now try to adapt exercise regimes and existing drugs to switch on AMPK in muscle more effectively. The development of new selective activators of the AMPK pathway in muscle may also be effective to prevent muscle loss with aging.

A new Iowa State University study focusing on insulin signaling uncovered surprising genetic diversity across reptiles, birds and mammals. Scientists previously assumed the process remained much the same throughout the animal kingdom, but the new research shows that the genetic pathways in reptiles evolved to include protein forms not observed in mammals.

Adults over 50 who have persistent symptoms of depression may have twice the risk of stroke as those who do not, according to a new study led by researchers at Harvard T.H. Chan School of Public Health. Researchers found that stroke risk remains higher even after symptoms of depression go away, particularly for women.

For the past 20 years, a large portion of the particles measured in the atmosphere were missing from models. At best, models were able to explain one-tenth of the carbon-rich secondary organic aerosols measured in the air. The problem turned out to be a series of fundamental assumptions used in the models due to a lack of experimental data. All of the assumptions were proven false by Dr. Alla Zelenyuk and her colleagues.

America’s population of senior citizens is growing, and with it, a reliance on canes, wheelchairs and scooters. This proliferation of senior mobility devices is surprising considering that prior research showed a correlation between device use and falling — the leading cause of death resulting from injury among adults 65 and older.

An enzyme secreted by the body’s fat tissue controls energy levels in the brain, according to new research at Washington University School of Medicine in St. Louis. The findings, in mice, underscore a role for the body’s fat tissue in controlling the brain’s response to food scarcity, and suggest there is an optimal amount of body fat for maximizing health and longevity.

Everyone knows that 60 is the new 50. But now, Warren Sanderson, a Professor of Economics at Stony Brook University, and Sergei Scherbov, a project leader at an Austrian research institute, have written an article about future population projections for Europe up to the year 2050 published in PLOS ONE, which shows that, counterintuitively, population aging is slower when life expectancy increase is faster – 60 really is the new 50.

We age in part thanks to “friendly fire” from the immune system — inflammation and chemically active molecules called reactive oxygen species that help fight infection, but also wreak molecular havoc, contributing to frailty, disability and disease. The CD33rSiglec family of proteins are known to help protect our cells from becoming inflammatory collateral damage, prompting researchers at the University of California, San Diego School of Medicine to ask whether CD33rSiglecs might help mammals live longer, too.

In work that reconciles two competing views of brain structures involved in memory and spatial perception, researchers at University of California, San Diego School of Medicine have conducted experiments that suggest the hippocampus – a small region in the brain’s limbic system – is dedicated largely to memory formation and not to spatial skills, such as navigation. The study is published in this week’s issue of the Proceedings of the National Academy of Sciences.

In people, a baby’s risk of congenital heart defects is associated with the age of the mother. Risk goes up with increasing age. Newborn mice predisposed to heart defects because of genetic mutations show the same age association. A new study demonstrates that older mouse mothers reduce this risk for their offspring to that of younger mouse mothers through exercise alone, according to researchers at Washington University School of Medicine in St. Louis.

Figuring out what’s happening at a cellular and molecular level may help scientists develop ways to treat or prevent age-related, neurogenerative diseases, such as Alzheimer’s and Parkinson’s. Through National Institutes of Health funding, pharmacy professor Xiangming Guan and his team at South Dakota State University, Guan and his team developed the first imaging reagent that can determine thiol levels in intact living cells. Now they are working on reagents that can selectively show thiol density in subcellular structures, specifically the nucleus and mitochondria. Guan hopes to develop a nontoxic reagent safe enough to be used for diagnostic imaging, like an MRI.

Raising the age of eligibility for the Old Age Security pension and the Guaranteed Income Supplement will increase inequalities between older people. “This change will force retired people into greater dependence on their private savings to support them as they get older. Research shows that greater privatisation of the retirement income system results in growing inequalities among the older population. When you raise the pension eligibility age, you are also opening the door to rising disparities” according to demographer Yves Carrière, of the University of Montreal, who presented, last week in Ottawa, a report on this topic to the Population Change and Life-course Strategic Knowledge Cluster meeting.
