Aging

A team of Harvard scientists has finally solved the mystery of how acute stress causes hair to turn gray. The researchers discovered when stress triggers the "fight or flight" response, it depletes pigment-producing stem cells in hair follicles.

A new study has examined the relationship between telomere length and intake of milk with different fat concentrations, suggesting there is a link between consumption of low-fat variants and longer telomeres that can equate to several years of aging.

Finding ways to slow down aging would help reduce all kinds of diseases. And now scientists have made a pretty substantial breakthrough, extending the lifespan of worms by a staggering 500 percent by tweaking a couple of cellular pathways.

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.
