Antiaging

The researchers tested common treatments for aging, including intermittent fasting which reduces calorie consumption, targeting a central node of cell metabolism (mTOR), and interfering with the release of growth hormone.A new study has examined the effectiveness of three treatment approaches that were previously thought to slow the aging process. However, when tested on mice, the researchers found that these treatments had a limited impact on aging.“There is no internal clock of aging that you can regulate with a simple…

Senescent cells are distinct in that they eventually stop multiplying but do not die off as expected.Senescent Cells Help To Heal Damaged TissuesAccording to a recent study from the University of California, San Francisco, not all senescent cells are detrimental “zombies” that need to be eliminated to avoid age-related diseases. Instead, some of them are embedded in young, healthy tissues and promote normal recovery from damage.Scientists have now seen these cells in action in lung tissue as well as other organs that…

A new study may suggest that a popular anti-aging supplement could come with associated cancer risks. The supplement in question is called nicotinamide riboside, and it is a variant of vitamin B3. While believed to help brain health, metabolism, and more, the pill may also increase the chance of both breast cancer and brain metastasis, the new study warns. The study suggests that high levels of NR, which is often referred to as an anti-aging vitamin, could increase the risk of developing cancer in…

The mechanism delays and, in some cases, prevents the natural aging of immune cells.The mechanism extends the life of the immune system. A multinational team headed by University College London scientists has discovered a new mechanism that slows down and maybe even prevents the normal aging of immune cells, one of the nine “hallmarks of aging.”The discovery in-vitro (cells) and validated in mice was “unexpected,” according to the researchers, who believe harnessing the mechanism might extend the life of the immune…

New research on aging in roundworms has thrown up some intriguing results, with scientists at Nanyang Technological University (NTU), Singapore finding they could increase the animals' lifespan by feeding them a high-sugar diet. Far from suggesting people adopt this lifestyle intervention, the authors say the breakthrough highlights a new mechanism underlying the aging process, and paves the way for new therapies to tackle age-related disease.“Aging is a critical risk factor for a variety of human pathologies, from…

Senescent cells are somewhat of a boogeyman lately, blamed for many of the unpleasant effects of aging. As such, they’re targeted by an increasing range of anti-aging therapies – but we might not want to wipe them all out, as a new study suggests that some senescent cells play positive roles in healing.Over the decades of our lives, our cells accumulate DNA damage that eventually causes them to stop dividing. These so-called senescent cells are usually cleared out by the immune system, but as we get older they begin to…

According to a clinical trial involving 55 to 70-year-old women, adding this nutrient to the diet can strengthen the body’s antioxidant defenses and possibly lower the chance of developing diabetes, high blood pressure, and cardiovascular disease. However, more research is needed to confirm its effect. According to the study, the amino acid taurine could be employed in anti-aging therapies.Our cells produce potentially toxic by-products known as “free radicals” when they break down the oxygen we breathe and the food we…

Rapamycin is currently the most promising anti-aging drug. Credit: Max Planck Institute for Biology of AgingBrief exposure to rapamycin has the same anti-aging effects as lifelong treatment.Imagine being able to take a medicine that prevents the decline that comes with age and keeps you healthy. Scientists are searching for drugs that have these effects. The current most promising anti-aging drug is Rapamycin. It is known for its positive effects on life and health span in experimental studies with laboratory animals. It…

A new anti-aging project is gaining ground and could eventually help dogs live longer.  The Dog Aging Project is a somewhat new and ambitious research effort that wants to track the aging process of thousands of dogs across the United States. The goal of the research is to find ways to extend the lifespan of dogs. And from there, we could see human age research innovations. Why scientists are researching how dogs age Image source: eufy/AmazonAs I noted above, the point of the Dog Aging Project, and other…

Although we generally understand exercise to be good fo us in all sorts of ways, scientists continue to make interesting inroads around the specifics of this relationship. The latest comes from a team in Germany which has found that even slight changes to regular physical activity, such as taking the stairs instead of the elevator, can counter the age-related loss of volume in brain regions linked to disease.Research has demonstrated how exercise can help combat some of the effects of aging. This includes studies showing…
