Aging adults have choices when confronting perceived mental declines
Aging adults may joke about memory lapses and "early Alzheimer's." They may worry when they can't understand a drug plan or lose track of the characters in a novel. view more (2007-08-03)
Few friends combined with loneliness linked to poor mental and physical health for elderly
Although not having many close friends contributes to poorer health for many older adults, those who also feel lonely face even greater health risks, research at the University of Chicago suggests. Older people who are able to adjust to being alone don't have the same health problems. view more (2009-03-19)
New vitamin K analysis supports the triage theory
An important analysis conducted by Children's Hospital Oakland Research Institute scientists suggests the importance of ensuring optimal dietary intakes of vitamin K to prevent age-related conditions such as bone fragility, arterial and kidney calcification, cardiovascular disease, and possibly cancer. view more (2009-09-18)
Calorie restriction appears better than exercise at slowing primary aging
Investigators at Washington University School of Medicine in St. Louis have found that eating a low-calorie yet nutritionally balanced diet lowers concentrations of a thyroid hormone called triiodothyronine (T3), which controls the body's energy balance and cellular metabolism. view more (2006-06-01)
Study finds mix of disease processes at work in brains of most people with dementia
Few older people die with brains untouched by a pathological process, however, an individual's likelihood of having clinical signs of dementia increases with the number of different disease processes present in the brain. view more (2007-06-14)
Common weed could provide clues on aging and cancer
A common weed and human cancer cells could provide some very uncommon details about DNA structure and its relationship with telomeres and how they affect cellular aging and cancer, according to a team led by scientists from Texas A&M University and the University of Cincinnati (UC). view more (2009-10-27)
Zeroing in on progeria: How mutant lamins cause premature aging
Children diagnosed with Hutchinson-Gilford Progeria Syndrome (HGPS) race through life against an unfairly fast clock. Cases are extremely rare-one in 8 million births-but time plays cruel tricks on HGPS newborns. view more (2005-12-14)
Agent in red wine found to keep hearts young
How, scientists wonder, do the French get away with a clean bill of heart health despite a diet loaded with saturated fats? view more (2008-06-04)
Weight gain early in life leads to physical disabilities in older adults
Carrying extra weight earlier in life increases the risk of developing problems with mobility in old age, even if the weight is eventually lost, according to new research out of the Sticht Center on Aging at Wake Forest University School of Medicine. view more (2009-04-07)
Forget the antioxidants? McGill researchers cast doubt on role of free radicals in aging
For more than 40 years, the prevailing explanation of why we get old has been tied to what is called oxidative stress. This theory postulates that when molecules like free radicals, oxygen ions and peroxides build up in cells, they overwhelm the cells' ability to repair the damage they cause, and the cells age. view more (2009-02-18)
Substance in red wine found to keep hearts young
How do the French get away with a clean bill of heart health despite a diet loaded with saturated fats? Scientists have long suspected that the answer to the so-called "French paradox" lies in red wine. Now, the results of a new study bring them closer to understanding why. view more (2008-06-05)
Wear and tear of stress: the psychoneurobiology of aging
Age may be more related to reactions to stress and the absence of disease rather than to a person's chronological age, say leading researchers in the fields of neurobiology and psychoneuroendocrinology. view more (2006-08-14)
'Master regulator' of skin formation discovered
Researchers at Oregon State University have found one gene in the human body that appears to be a master regulator for skin development, in research that could help address everything from skin diseases such as eczema or psoriasis to the wrinkling of skin as people age. view more (2009-03-25)
Functional brain imaging in the dog.
Single photon emission tomography is an imaging modality using radiolabelled tracer substances to investigate function and metabolism of various organs in the living patient. We explored this technique in the dog to investigate brain function. Brain perfusion (an indirect indicator for metabolism and related brain function) was measured in normal... view more...

Link identified between age, cardiovascular disease
Researchers in the Linus Pauling Institute at Oregon State University have discovered a fundamental mechanism that causes aging blood vessels to lose their elasticity - a literal "hardening of the arteries" that is often a prelude to high blood pressure and cardiovascular disease. view more (2006-11-06)
Good news for a fast-wrinkling generation: Some anti-aging methods work
Fine wrinkles, deeper creases, saggy areas around the mouth and neck - the sights in the mirror that make baby boomers wince - are not inevitable. They result from a structural breakdown inside the skin that some existing treatments effectively counteract by stimulating the growth of new, youthful collagen, University of Michigan scientists say. view more (2008-05-29)
No proof that growth hormone therapy makes you live longer, Stanford study finds
Surveyors of anti-aging elixirs tout human growth hormone as a remedy for all things sagging-from skin to libidos-and claim it can even prevent or reverse aging. view more (2007-01-16)
Animal study suggests inadequate sleep may exacerbate cellular aging in the elderly
Researchers at the University of Pennsylvania School of Medicine have shown that the unfolded protein response, which is a reaction to stress induced by sleep deprivation, is impaired in the brains of old mice. view more (2008-06-30)
Mental declines can be reversed-report shows
As we get beyond retirement age, most of us will not be as mentally sharp as we once were. But a researcher at the University of Alberta says most people have the ability to reverse the mental declines that come with aging. view more (2005-09-19)
Age-related memory loss tied to slip in filtering information quickly
Scientists have identified a way in which the brain's ability to process information diminishes with age, and shown that this break down contributes to the decreased ability to form memories that is associated with normal aging. view more (2008-09-03)
