Some signs of aging may actually be indicators of diabetes – from vision and hearing loss to longer healing times from cuts and bruises. The American Association of Diabetes Educators (AADE) provides information on these “sneaky” symptoms for those 45 and older.
It’s something we’ve all heard for years: Exercise can help keep older adults healthy. But now a study, the first of its kind, proves that physical activity can help older adults maintain their mobility and dodge physical disability.
Exercise changes the lives of inactive older adults, according to a major new study. Researchers will unveil the results of a study investigating how physical activity affects older adults. The multi-year study, the most comprehensive study of exercise and aging to date, spanned eight field centers and involved more than 1,600 participants. Newswise is offering reporters a behind-the-scenes look at the state of the research and the impact it might have on global public health by interacting with two leading scientists in the field of aging and exercise.
The American Academy of Dermatology (Academy) today launched “Lawn,” a public service advertisement (PSA) that encourages older men to check their skin for suspicious or changing spots. Although melanoma, the deadliest form of skin cancer, can strike anyone, men older than 50 are at a higher risk of developing melanoma than the general population.
Faleh Tamimi, a professor in McGill’s School of Dentistry, is the leader of a research team that has just discovered that melatonin supplements make bones stronger in elderly rats and therefore, potentially, in elderly humans too.

A commonly prescribed antidepressant can reduce production of the main ingredient in Alzheimer’s brain plaques, according to new research at Washington University School of Medicine in St. Louis and the University of Pennsylvania.
A study identifies a new molecular circuit that controls longevity in yeast and more complex organisms and suggests a therapeutic intervention that could mimic the lifespan-enhancing effect of caloric restriction, no dietary restrictions necessary. The team looked for answers in the ISW2 protein, and found that its absence alters gene expression involved in DNA damage protection. Deletion of ISW2 increases the expression and activity of genes in DNA-damage repair pathways –also seen in calorie restriction.
What is the secret to aging more slowly and living longer? Not antioxidants, apparently. Many people believe that free radicals, the sometimes-toxic molecules produced by our bodies as we process oxygen, are the culprit behind aging. Yet a number of studies in recent years have produced evidence that the opposite may be true.
New research suggests that certain types of brain cells may be “picky eaters,” seeming to prefer one specific energy source over others. The finding has implications for understanding the cognitive decline seen in aging and degenerative diseases such as Alzheimer’s and multiple sclerosis.
A strong handshake can say a lot about a person—it can indicate power, confidence, health, or aggression. Now scientists at Stony Brook University and the Institute for Applied Systems Analysis (IIASA) say that the strength of a person’s grasp may also be one of the most useful ways to measure people’s true age. About IIASA: IIASA is an international scientific institute that conducts research into the critical issues of global environmental, economic, technological, and social change that we face in the twenty-first century. Our findings provide valuable options to policy makers to shape the future of our changing world.

With lifespans of up to 31 years, naked mole rats live decades longer than would be expected based on their size. A new study links their remarkable lifespans to high levels of a quality-control protein, offering new insights on age-related diseases like Alzheimer’s and Parkinson’s.
Unhealthy lifestyle habits can accelerate the process of senescence (cell death) and the release of damaging substances from dying cells. Researchers at the Mayo Clinic for the first time demonstrate that exercise can prevent or delay this fundamental process of aging.
The stress hormone cortisol can negatively affect memory and learning ability in the elderly. Researchers at Loma Linda University found that showing a 20-minute funny video to healthy seniors and seniors with diabetes helped them score better on memory tests and significantly reduced their cortisol levels when compared to non-video watchers.

Heart patients with irrational health beliefs - such as doubting the preventive value of a flu vaccine - are more likely to skip cardiac rehab sessions, new research suggests.
A new study from UAB highlights why fibrotic diseases — diseases that feature fibrosis or scarring of organ tissue — are typically associated with aging. Fibrosis, the formation of fibrous scar tissue in response to injury, is part of the normal healing process. In young animals or people, scars resolve or fade away over time and are replaced by newly grown healthy tissue. In older subjects, the scars do not resolve or fade, and scar tissue can build up. In organs such as the heart, lungs, kidneys or liver, the buildup of scar tissue can interfere with normal function, with potentially devastating results. In findings published in Science Translational Medicine, the UAB team describes the mechanism that contributes to persistent fibrosis in the aged, and suggests targets that may help reverse the buildup of scar tissue.
Using a screening method that previously identified a compound in apple peel as a muscle-boosting agent, a team of University of Iowa scientists has now discovered that tomatidine, a compound from green tomatoes, is even more potent for building muscle and protecting against muscle atrophy.
Three neuroscientists discuss the emerging consensus on age-related memory loss and what researchers hope to learn in coming years.

Study suggests people are less timid about broaching end-of-life planning and talking about death.
The latest results from a 25-year study of diet and aging in monkeys shows a significant reduction in mortality and in age-associated diseases among those with calorie-restricted diets. The study, begun at the University of Wisconsin-Madison in 1989, is one of two ongoing, long-term U.S. efforts to examine the effects of a reduced-calorie diet on nonhuman primates.
Physicians have long suspected that chemotherapy can accelerate the aging process in patients treated for cancer. Using a test developed at UNC Lineberger Comprehensive Cancer Center to determine molecular aging, UNC oncologists have directly measured the impact of anti-cancer chemotherapy drugs on biological aging.
People who develop diabetes and high blood pressure in middle age are more likely to have brain cell loss and other damage to the brain, as well as problems with memory and thinking skills, than people who never have diabetes or high blood pressure or who develop it in old age, according to a new study published in the March 19, 2014, online issue of Neurology®, the medical journal of the American Academy of Neurology. Middle age was defined as age 40 to 64 and old age as age 65 and older.
New research suggests that the more muscle mass older Americans have, the less likely they are to die prematurely. The findings add to the growing evidence that overall body composition — and not the widely used body mass index, or BMI — is a better predictor of all-cause mortality.
Study with mice shows moderate exercise can activate Nrf2, leading to stem cell regeneration.
