A sub-study, which was part of the large-scale VITAL trial, determined that vitamin D supplementation slows telomere attrition in leukocytes almost to a halt. This could have real-life clinical implications [1]. The chromosome guardians Attrition of telomeres, repetitive sequences that cap chromosomes, is one of the original hallmarks of aging. Our cells' replication machinery does...

What is aging? Sadly, we don’t know. If we ask the experts in the field, they will give us different answers [1]. Consensus has not been reached on even the trivial definition of aging, let alone its primary mechanisms. But, can we cure aging without understanding it? I think not. Knowledge is essential to target...

For most of the history of human civilization, humanity expanded at an astonishing pace: faster than exponential, nearly hyperbolic. This trend was famously described in a 1960 paper by Heinz von Foerster and colleagues, who extrapolated global population data to predict a so-called "Doomsday", a demographic singularity in which human numbers would become infinite by...

Science is Working on Therapies For Healthy Longevity People call it life extension, anti-aging, age-reversal, longevity research, geroscience, rejuvenation biotechnology, and even biomedical gerontology but what exactly is it? What life extension is While life extension is technically correct, it is somewhat more nuanced than simply just increasing lifespan. It describes the development of advanced...

How Sleep Apnea Accelerates Biological Aging
Alarmingly common yet routinely ignored, severe untreated obstructive sleep apnea can steal 7 to 8 years of life, second only to cigarette smoking (~10 years lost) and far exceeding the losses linked to lifelong physical inactivity (~3 years) or persistently high mid-life cholesterol (~1 to 2 years) [1-5].

Why We Age: Dysbiosis
In youth, the human gut is buzzing with a mix of helpful microbes working in harmony. With aging, however, that harmony fades, replaced with inflammation-stirring bugs that happily sip on your bile acids. This slide is so consistent that López-Otín and colleagues upgraded “dysbiosis” from bit player to full-fledged hallmark, grouping it with chronic inflammation at the “integrative” tier of aging biology.

Why We Age: Chronic Inflammation
Chronic inflammation refers to a persistent, low-grade buzz of immune activity that settles into the body without the drama of an infection or obvious injury. In the world of aging, this slow, smoldering fire is often called inflammaging, a term coined by Claudio Franceschi to capture the systemic, hard-to-detect inflammation that creeps in with advancing years.

Low-Dose Naltrexone: Benefits and Side Effects
Naltrexone is an FDA-approved medication for the treatment of opioid addiction and alcohol dependence that was developed in 1961. Naltrexone blocks the action of opioids at three key receptors that regulate a range of bodily functions, including immune function; cell growth and proliferation; and mood and cognition.

Why We Age: Disabled Macroautophagy
In autophagy, damaged proteins and organelles are wrapped in a double-membraned autophagosome structure. These sacs then join with lysosomes, which act like molecular incinerators. They break down waste and recycle the parts. However, as cells age, this well-oiled system falters. Autophagosomes form more slowly. Lysosomes lose their acidic power, and the cell's waste builds up.

Why We Age: Cellular Senescence
As your body ages, more of your cells become senescent. Senescent cells do not divide or support the tissues of which they are part; instead, they emit potentially harmful chemical signals, collectively known as the senescence-associated secretory phenotype (SASP), which encourages nearby cells to enter the same senescent state. Their presence causes many problems: they degrade tissue function, increase chronic inflammation, and can even eventually raise the risk of cancer and other age-related ...

The Reasons We Age - Hallmarks of Aging
There are multiple aging theories, but one of the most popular and well supported is the Hallmarks of Aging, a 2013 paper that defined aging as nine distinct categories (hallmarks) and explained how these interact with each other to drive the development of age-related diseases. This framework gives researchers insights into how they might directly intervene against these aging processes to prevent age-related diseases.
