    MONDAY, Oct. 19 (HealthDay News) -- Surfing the Internet just might be a way to preserve your mental skills as you age. Researchers found that older adults who started browsing the Web experienced improved brain function after only a few days. "You can teach an old brain new technology tricks," said Dr. Gary Small, a psychiatry professor at the Semel Institute for Neuroscience and Human Behavior at the University of California, Los Angeles, and the author of iBrain. With people who had little Internet experience, "we found that after just a week of practice, there was a much greater extent...

    Vienna (dpa) -- A substance contained in sperm fluid prolongs life and might be used in fighting Alzheimer disease, Austria's Graz University announced Monday. Researchers Tobias Eisenberg and Frank Madeo have found that the substance spermidine extends the lifespan of human immune cells, as well as of mice, flies, worms and yeast fungus. "We might have found the holy grail of age research," said Eisenberg, whose study involved 29 colleagues in six countries and was published in the British journal Nature Cell Biology on Sunday. In tests with mice treated with spermidine, cell damage linked to aging was reduced, and...

    Could a pill one day slow ageing in humans?Punchstock Rapamycin, a drug commonly used in humans to prevent transplanted organs from being rejected, has been found to extend the lives of mice by up to 14% — even when given to the mice late in life. In flies and worms, drug treatments have been shown to prolong lifespan, but until now, the only robust way to extend life in mammals has been to heavily restrict diet. The researchers caution, however, that using this drug to extend the lifespan of humans might be problematic because it suppresses the immune system —...

    The American Medical Association is taking on a segment of the $50 billion "anti-aging" industry that promotes the use of hormones as a treatment for consumers to slow or reverse the aging process. In a report presented Sunday in Chicago to a committee of the AMA's 543-member policymaking House of Delegates, the AMA Council on Science and Public Health calls into question claims made by for-profit Web sites, anti-aging clinics and other businesses promoting hormones as anti-aging treatments. "Despite the widespread promotion of hormones as anti-aging agents by for-profit Web sites, anti-aging clinics and compounding pharmacies, the scientific evidence to...

    Mental powers start to dwindle at 27 after peaking at 22, marking the start of old age, US research suggests. Professor Timothy Salthouse of Virginia University found reasoning, speed of thought and spatial visualisation all decline in our late 20s. Therapies designed to stall or reverse the ageing process may need to start much earlier, he said. His seven-year study of 2,000 healthy people aged 18-60 is published in the journal Neurobiology of Aging. To test mental agility, the study participants had to solve puzzles, recall words and story details and spot patterns in letters and symbols. The same tests...

    Getting old already? 27-year-old singer Beyonce Knowles is already past her mental peak according to new research According to scientists, our mental abilities begin to decline from the age of 27 after reaching a peak at 22. The researchers studied 2,000 men and women aged 18 to 60 over seven years. The people involved – who were mostly in good health and well-educated – had to solve visual puzzles, recall words and story details and spot patterns in letters and symbols. The first age at which performance was significantly lower than the peak scores was 27 – for three tests...

The pores that permit only certain molecules to enter and exit the nuclei of our cells start leaking. A new study raises the possibility that permissive pores trigger some of the physical decline of old age. Nuclear pores aren't mere portholes. Each consists of about 30 different proteins called nucleoporins that control what...

    Improving blood flow to brain is a preventive strategy CHICAGO --- A slow, chronic starvation of the brain as we age appears to be one of the major triggers of a biochemical process that causes some forms of Alzheimer's disease. A new study from Northwestern University's Feinberg School of Medicine has found when the brain doesn't get enough sugar glucose -- as might occur when cardiovascular disease restricts blood flow in arteries to the brain -- a process is launched that ultimately produces the sticky clumps of protein that appear to be a cause of Alzheimer's.

    ScienceDaily (Dec. 20, 2008) — It turns out there's a scientific reason why older people tend to see the past through rose-colored glasses. Medical researchers have identified brain activity that causes older adults to remember fewer negative events than their younger counterparts. Neuroscientists from Duke University Medical Center have discovered that older people use their brains differently than younger people when it comes to storing memories, particularly those associated with negative emotions.

    Adding another reason for people to watch their blood pressure, a new study from North Carolina State University shows that increased blood pressure in older adults is directly related to decreased cognitive functioning, particularly among seniors with already high blood pressure. This means that stressful situations may make it more difficult for some seniors to think clearly.

    HAVANA – In the palace of a fallen dictator, the grade-school kids in their red Communist Pioneer bandanas are getting their mandatory introduction to the glories of the revolution. Clattering from one display case to the next, they gaze wide-eyed at an antique gun, a fighter's bloodied shirt, the engine of a downed U.S. spy plane. Moving on, they stare at the yacht named Granma that carried Fidel Castro back from exile to launch his guerrilla war, and the combat boots his brother-successor wore as a ponytailed 27-year-old rebel.

    Harvard Medical School scientists claim to have discovered a mechanism that may be the universal cause of aging. The study, published in the journal Cell, shows how DNA damage eventually leads to a breakdown in the cell’s ability to understand which genes are switched on and which are switched off. The cell’s decreasing ability to detect patterns of gene expression plays a critical role in aging, the researchers report. “This is the first potentially fundamental, root cause of aging that we've found,” says Harvard Medical School professor of pathology David Sinclair. “There may very well be others, but our finding...

Credit: Courtesy of Philipp Oberdoerffer/Harvard Medical School It seems there's just no way to beat Father Time. As we age, our chromosomes fracture, and specialized proteins rush in to reverse the damage. But new research shows that in doing so, these proteins inadvertently switch on genes that can contribute to aging, allowing senescence to march ever onward. The idea that a protein might patch up a rickety, aging chromosome is not...

    A new insight into the reason for aging has been gained by scientists trying to understand how resveratrol, a minor ingredient of red wine, improves the health and lifespan of laboratory mice. They believe that the integrity of chromosomes is compromised as people age, and that resveratrol works by activating a protein known as sirtuin that restores the chromosomes to health. The finding, published online Wednesday in the journal Cell, is from a group led by David Sinclair of the Harvard Medical School. It is part of a growing effort by biologists to understand the sirtuins and other powerful agents...

    The housing crisis has kept thousands of older Americans who need support and care from moving into retirement communities or assisted-living centers, effectively stranding them in their own homes. Without selling their houses or condominiums, many cannot buy into retirement homes that require a payment of $100,000 to $500,000 just to move in. So they are scratching themselves off waiting lists, canceling plans with packing services and staying put, in houses that fit well 30 years ago, but over the years have become lonely, too large or too treacherous to navigate. “It is part of the hidden problem of the...
