Live fast, die young? Maybe not
The theory that a higher metabolism means a shorter lifespan may have reached the end of its own life, thanks to a study published in the journal Physiological and Biochemical Zoology. The study, led by Lobke Vaanholt (University of Groningen, The Netherlands), found that mice with increased metabolism live just as long as those with slower... view more... (2009-03-10)
Researchers discover that growing up too fast may mean dying young in honey bees
Reactive oxygen species (ROS) occur as a by-product of aerobic metabolism and impair cellular function by damaging proteins, nucleotides and lipids. view more (2008-09-25)
An Anti-Frailty Pill for Seniors?
Researchers at the University of Virginia Health System report that a daily single oral dose of an investigational drug, MK-677, increased muscle mass in the arms and legs of healthy older adults without serious side effects, suggesting that it may prove safe and effective in reducing age-related frailty. view more (2008-11-05)
Topical application of chemotherapy drug may improve appearance of aging skin
Topical application of the chemotherapy medication fluorouracil appears to reduce potentially precancerous skin patches and improve the appearance of sun-damaged skin. view more (2009-06-16)
Scripps research scientists find cause of cartilage degeneration in osteoarthritis
The scientists describe their work in this week's Early Edition of the Proceedings of the National Academy of Sciences. In the study, the team shows how the loss of the protein HMGB2, found in the surface layer of joint cartilage, leads to the progressive deterioration of the cartilage that is the hallmark of osteoarthritis. view more (2009-01-13)
Scientists Discover New Planet Orbiting Dangerously Close to Giant Star
A team of astronomers from Penn State and Nicolaus Copernicus University in Poland has discovered a new planet that is closely orbiting a red-giant star, HD 102272, which is much older than our own Sun. view more (2008-11-19)
Vitamin D protects cells from stress that can lead to cancer
By inducing a specific gene to increase expression of a key enzyme, vitamin D protects healthy prostate cells from the damage and injuries that can lead to cancer, University of Rochester Medical Center researchers report. view more (2008-05-14)
Ben-Gurion U of the Negev study demonstrates link between appetite and elderly mortality
A new study by a Ben-Gurion University of the Negev (BGU) researcher reveals a linkage between elderly people's appetite and mortality rates, with those who report impaired appetite more likely to die sooner. view more (2009-05-12)
Study: Personality traits associated with stress and worry can be hazardous to your health
Personality traits associated with chronic worrying can lead to earlier death, at least in part because these people are more likely to engage in unhealthy behaviors, such as smoking, according to research from Purdue University. view more (2009-08-19)
For elderly, extra pounds may lower mortality rates
If you're more than 80 years old, carrying a few extra pounds might not be such a bad idea. In fact, it may be beneficial. view more (2006-05-16)
Post-mortem brain studies reveal features of mild cognitive impairment
The brains of patients with mild cognitive impairment display pathologic features that appear to place them at an intermediate stage between normal aging and Alzheimer's disease, although some patients with mild cognitive impairment develop other types of dementia. view more (2006-05-09)
Experienced air traffic controllers work smarter, not harder, making up for normal mental aging
Older air traffic controllers can head off mid-air collisions at least as well as younger controllers, using experience to compensate for age-related declines in mental sharpness, a new study finds. The evidence that experience triumphs over the normal changes of aging could help to overturn myths about older workers that are contributing to the... view more... (2009-03-13)
Overweight middle-aged women cut chances of enjoying healthy old age
Women who put on weight as they approach middle-age could reduce their chances of enjoying a healthy old age by up to 80%, according to research from the University of Warwick. view more (2009-09-30)
Blocking a premature aging syndrome with anticancer drugs
A class of anticancer drugs currently being evaluated in phase 3 clinical trials may also be an effective treatment for Hutchinson-Gilford progeria syndrome (HGPS), a fatal genetic disorder that causes premature aging. view more (2005-08-30)
Carbon dioxide laser resurfacing may reduce wrinkles over long term
Carbon dioxide laser resurfacing appears to be an effective long-term treatment for facial wrinkles, according to a report in the July/August issue of Archives of Facial Plastic Surgery, one of the JAMA/Archives journals. view more (2008-07-22)
Diabetes research takes wing thanks to long-lived fruit fly
The creation of an extraordinarily long-lived fruit fly by genetics researchers at the University of Rochester has led scientists down an unexpected new path in the fight against diabetes. view more (2006-06-08)
Study examines testing model to predict and diagnose new cases of dementia
A report published by researchers at Albert Einstein College of Medicine of Yeshiva University in the August 20 issue of JAMA suggests that measuring how much an individual's performance varies across several neuropsychological tests enhances the accuracy of predicting whether older adults will develop dementia. view more (2008-08-20)
Naked mole-rat unfazed by oxidative stress
The long-lived naked mole-rat shows much higher levels of oxidative stress and damage and less robust repair mechanisms than the short-lived mouse, findings that could change the oxidative stress theory of aging. view more (2006-10-09)
UCLA finds cancer drug may improve progeria; genetic disease causes accelerated aging in children
UCLA researchers found that an experimental cancer drug improves the signs of progeria in a mouse model. Progeria is a rare genetic disease causing accelerated aging and cardiovascular disease in children. view more (2006-02-17)
Study finds estrogen therapy gives aging brain cells a boost
Cyclical, long-term estrogen injections protected brain cells from age-related deterioration, according to a new study conducted at Mount Sinai School of Medicine. view more (2007-06-26)
