Aging

Scientists are homing in on exactly how two experimental Alzheimer’s drugs may be generating the anti-aging effects seen in animal studies. The discovery of a unique metabolic pathway offers researchers novel directions for future anti-aging studies.

The blood-borne signs of aging – and indeed, perhaps the causes of agiing – make three big shifts around the ages of 34, 60 and 78, a new Stanford-led study has found, potentially leading to new diagnostic tests and avenues of anti-aging research.

In a new study, researchers looked at the immune systems of people who have hit the milestone of 110 years old, and found that they have a high number of a particular type of immune cell that’s rare even in healthy, younger people.

A new study is suggesting a metabolite called called butyrate, produced by gut microbes, could increase neuron production in the brain, improve intestinal function, and ultimately slow the aging process.

A landmark new study is strongly linking excessive neural activity with shorter lifespans. The study suggests a protein known to suppress neural excitation affects a number of longevity pathways, effectively slowing the aging process.

Gait speed, or the pace at which a person walks, has been effectively used as a biomarker for health in older subjects. A new study is now suggesting that gait speed may be an effective measure of biological aging for someone in their 40s.

Researchers have extend the lifespan of fruit flies by 48 percent using a triple drug combination made up of drugs already used in people.

A study is suggesting aerobic exercise may be more effective than flexibility training in directly reducing hippocampal deterioration linked to Alzheimer's.

New research, led by a team from the University of Cambridge, has demonstrated a way to rejuvenate old brain stem cells, making them act young again. The technique points to potential new treatments for multiple sclerosis (MS), but also broader ways to reverse general age-related brain changes.

Electrical stimulation of the vagus nerve holds all kinds of possibilities in medical science, and scientists have now added another to the list by demonstrating how targeting it through the ear could help slow some of the effects of aging. ​

​According to a new study, seniors wishing to boost their cognitive performance would likely do well to drink plenty of Montmorency tart cherry juice. Improvements observed in test subjects who drank the juice may be due to "bioactive compounds" that occur naturally in the cherries.

​There is no shortage of scientists toiling away in the field of anti-aging. This line of inquiry has turned up yet another interesting discovery, this time demonstrating how a certain chemical compound works to keep cells active and young.
