By now, the race to discover regenerative factors present in blood has been underway for a number of years, with numerous researchers seeking a “secret sauce” in blood that has
Trimethylamine May be Involved in Vascular Aging
July 10, 2020
Researchers suggest that trimethylamine, a metabolic byproduct that is created when bacteria in the gut break down foods such as red meat, may be a key player in vascular aging.
Selectivity of the Blood-Brain Barrier Changes with Age
July 9, 2020
The mechanisms at work in the blood-brain barrier change with age, affecting the selectivity of this vital interface. The blood-brain barrier The blood-brain barrier is a layer of cells in
Frailty and Age-Related Immune Decline Reversed in Mice
July 8, 2020
Frailty and the decline of the immune system are two typical features of aging, but new research shows that both can be halted and even somewhat reversed using a novel
Repetitions in Our DNA React to Anti-Aging Interventions
July 7, 2020
A group of scientists from Colorado State University has discovered that repetitive elements (REs) in our DNA increase with aging and react to known longevity-promoting interventions [1]. Are REs genomic
Scientists Induce a New Mode of Aging in Yeast
July 28, 2020
A group of researchers has shown that yeast cells have two different and mutually exclusive modes of aging that seem to be interlinked. The scientists were also able to artificially induce a third mode of aging that prolongs both healthspan and lifespan. Yeast is a popular
A Single Molecule Can Regenerate the Gut Lining
July 27, 2020
New research from Monash University has shown that a single key molecule responsible for cell adhesion and a variety of other bodily functions is also critical in repairing the gut lining and that increasing the presence of this molecule accelerates its repair and regeneration. Supercharging stem
A DNA Methylation Clock to Measure Skin Age
July 24, 2020
A team of researchers have developed a tissue-specific clock that can measure the biological age of skin. There is plenty of new evidence that different organs and tissues in our body age at different rates. In particular, the epigenetic state, the pattern of gene expression, of
Why NAD+ Declines During Aging – Part 1
July 23, 2020
There has been considerable debate around the age-related decline of NAD+, particularly regarding whether or not it occurs in humans as it does in other species, such as mice. Today, as part of a two-part special, we are going to be taking a look at some
Are Epigenetic Clocks Ready for Prime Time?
July 22, 2020
Reason, author of the anti-aging blog Fight Aging and CEO of Repair Biotechnologies, still isn’t convinced that methylation is very useful in assessing biological age or the efficacy of various therapeutics, despite the wide use of methylation-based clocks. He surprised me at this year’s Longevity Therapeutics
