During this year’s National Nursing Home Week (May 11-17), Dr. James Ellor, Ph.D., professor in Baylor University’s School of Social Work and gerontology expert, offers six questions people should ask while investigating – and before choosing – a nursing home.
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. IIASA is independent and funded by scientific institutions in Africa, the Americas, Asia, Oceania, and Europe. www.iiasa.ac.at

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.
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 and an author who has investigated the research for over a decade. With all the elements of a great story, the search for healthful human longevity sheds light on discoveries that could fundamentally reshape human life.

Older people who have apathy but not depression may have smaller brain volumes than those without apathy, according to a new study published in the April 16, 2014, online issue of Neurology®, the medical journal of the American Academy of Neurology. Apathy is a lack of interest or emotion.

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.
New research by Canadian sports medicine physician Mark Tarnopolsky, MD, PhD, suggests that a person can slow the speed at which they age by exercising regularly.
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.
A new study suggests that Alzheimer’s disease may contribute to close to as many deaths in the United States as heart disease or cancer. The research is published in the March 5, 2014, print issue of Neurology®, the medical journal of the American Academy of Neurology.

The accumulation of age-associated changes in a biochemical process that helps control genes may be responsible for some of the increased risk of cancer seen in older people, according to a National Institutes of Health study.
A chemical that's found in fruits and vegetables from strawberries to cucumbers appears to stop memory loss that accompanies Alzheimer's disease in mice, scientists at the Salk Institute for Biological Studies have discovered. In experiments on mice that normally develop Alzheimer's symptoms less than a year after birth, a daily dose of the compound----a flavonol called fisetin----prevented the progressive memory and learning impairments. The drug, however, did not alter the formation of amyloid plaques in the brain, accumulations of proteins which are commonly blamed for Alzheimer's disease. The new finding suggests a way to treat Alzheimer's symptoms independently of targeting amyloid plaques.
The ultraviolet radiation (UVR) present in sunlight is the most common environmental carcinogen. To develop better methods of protection from the sun, we need to understand how the human skin detects and responds to UVR. Researchers provide new insight into the molecular pathway underlying this process.
