Food additive inhibits longevity enzyme in yeast, increases cell toxicity, new study finds
A common additive found in food and cosmetics has been found to inhibit the activity of sirtuins, enzymes associated with lifespan control in yeast and other organisms, according to a new study led by researchers at the University of California, Berkeley. view more (2005-12-16)
Circadian rhythm-metabolism link discovered
UC Irvine researchers have found a molecular link between circadian rhythms - our own body clock - and metabolism. The discovery reveals new possibilities for the treatment of diabetes, obesity and other related diseases. view more (2008-07-25)
Researchers detail how aging undermines bone healing
Researchers have unraveled crucial details of how aging causes broken bones to heal slowly, or not at all, according to study results published today in the Journal of Bone and Mineral Research. The research team also successfully conducted preclinical tests on a potential new class of treatments designed to "rescue" healing capability... view more... (2009-01-16)
Vitamin extends life in yeast, Dartmouth Medical School researchers find
Imagine taking a vitamin for longevity! Not yet, but a Dartmouth discovery that a cousin of niacin prolongs lifespan in yeast brings the tantalizing possibility a step closer. view more (2007-05-04)
Iron-moving malfunction may underlie neurodegenerative diseases, aging
A glitch in the ability to move iron around in cells may underlie a disease known as Type IV mucolipidosis (ML4) and the suite of symptoms---mental retardation, poor vision and diminished motor abilities---that accompany it, new research at the University of Michigan shows. view more (2008-09-23)
Caring for the caregiver: Redefining the definition of patient
One quarter of all family caregivers of Alzheimer's disease patients succumb to the stress of providing care to a loved one and become hospital patients themselves, according to an Indiana University study published in the November 2008 issue of the Journal of General Internal Medicine. view more (2008-11-11)
The aging brain: Failure to communicate
A team of Howard Hughes Medical Institute researchers has shown that normal aging disrupts communication between different regions of the brain. view more (2007-12-06)
Scientists find molecular trigger that helps prevent aging and disease
Researchers at Mount Sinai School of Medicine set out to address a question that has been challenging scientists for years: How do dietary restriction-and the reverse, overconsumption-produce protective effects against aging and disease? view more (2009-11-19)
Researchers find connection between caloric restriction and longevity
For nearly 70 years scientists have known that caloric restriction prolongs life. In everything from yeast to primates, a significant decrease in calories can extend lifespan by as much as one-third. But getting under the hood of the molecular machinery that drives this longevity has remained elusive. view more (2007-09-21)
Challenging conventional wisdom: advances in development reverse fertility declines, says Penn study
A team of researchers at the University of Pennsylvania and the Università Bocconi in Milan have released a study that challenges one of the most established and accepted standards in the social sciences: Human fertility levels tend to decline as countries advance towards high levels of social and economic development. view more (2009-08-06)
Valve disease study suggests new public health concern, say Mayo Clinic researchers
Research from Mayo Clinic estimates that about 5 million adult Americans have moderate or severe heart valve disease as a consequence of aging, according to a Mayo Clinic study published online in The Lancet. view more (2006-08-23)
Size matters: Obesity leading risk factor of left atrial enlargement during aging
Aside from aging itself, obesity appears to be the most powerful predictor of left atrial enlargement (LAE), upping one's risk of atrial fibrillation (the most common type of arrhythmia), stroke and death. view more (2009-11-10)
UGA study finds physical, emotional burden of breast cancer lingers for older survivors
Surviving breast cancer is both a physical and an emotional ordeal, but the consensus among researchers is that life generally returns to normal for most women within two years of completing treatment. view more (2007-04-06)
Depression may increase Alzheimer's risk in people with memory problems
People with memory problems who are depressed are more likely to develop Alzheimer's disease than those who aren't depressed, according to a new UCLA study. view more (2009-06-16)
Type A personality is not linked to heart disease in large study
Although human genes contribute significantly to a person's health and behavior, these two kinds of traits aren't closely linked at all. view more (2006-08-30)
Study: Fountain of youth for your heart?
An age-related decline in heart function is a risk factor for heart disease in the elderly. While many factors contribute to a progressive age-related decline in heart function, alterations in the types of fuels the heart uses to produce energy also play important roles. view more (2007-11-05)
Aging heart changes shape, shrinks and loses pumping function too
Researchers at Johns Hopkins have evidence to explain why the supposedly natural act of aging is by itself a very potent risk factor for life-threatening heart failure. view more (2007-11-05)
UMCES-led research team quantifies nutrient pollution reductions from urban stream restoration
A team of researchers led by University of Maryland Center for Environmental Science researcher Dr. Sujay Kaushal has been among the first able to quantify the amount of excess nitrogen removed from an urban stream during environmental restoration projects. view more (2008-05-01)
New culprit for viral infections among elderly -- an overactive immune response
Researchers at Yale School of Medicine have found that exaggerated responses of the immune system explain why the elderly succumb to viral infections more readily than younger people. view more (2009-11-19)
Lack of deep sleep may increase risk of type 2 diabetes
Suppression of slow-wave sleep in healthy young adults significantly decreases their ability to regulate blood-sugar levels and increases the risk of type 2 diabetes. view more (2008-01-02)
