Your Blood Could Be Aging Your Brain, Increasing Risk of Dementia

Posted by in categories: biotech/medical, life extension, neuroscience

Our brains change more rapidly at various times of our lives, as though life’s clock was ticking faster than usual. Childhood, adolescence and very old age are good examples of this.

Yet for much of adulthood, the same clock seems to tick fairly regularly. One lap around the Sun; one year older.

However, there may be a stage of life when the brain’s clock starts speeding up. The brain starts changing without you necessarily noticing it. It may even be caused (partly) by what’s in your blood.

Can epigenetic reprogramming reverse aging?

Posted by in categories: biotech/medical, chemistry, genetics, life extension

The field of aging research has made significant progress over the last three decades, reaching a stage where we now understand the underlying mechanisms of the aging process. Moreover, the knowledge has broadened to include techniques that quantify aging, decelerate its process, as well as sometimes reverse aging.

To date, twelve hallmarks of aging have been identified; these include reduced mitochondrial function, loss of stem cells, increased cellular senescence, telomere shortening, and impaired protein and energy homeostasis. Biomarkers of aging help to understand age-related changes, track the physiological aging process and predict age-related diseases [1].

Longevity. Technology: Biological information is stored in two main ways, the genomes consisting of nucleic acids, and the epigenome, consisting of chemical modifications to the DNA as well as histone proteins. However, biological information can be lost over time as well as disrupted due to cell damage. How can this loss be overcome? In the 1940s, American mathematician and communications engineer Claude Shannon came up with a neat solution to prevent the loss of information in communications, introducing an ‘observer’ that would help to ensure that the original information survives and is transmitted [2]. Can these ideas be applied to aging?

Psat1-generated α-ketoglutarate and glutamine promote muscle stem cell activation and regeneration

Posted by in categories: biotech/medical, life extension

Alpha ketoglutarate, or AKG, has long been used as a dietary supplement in the bodybuilding world.


By satisfying bioenergetic demands, generating biomass, and providing metabolites serving as cofactors for chromatin modifiers, metabolism regulates adult stem cell biology. Here, we report that a branch of glycolysis, the serine biosynthesis pathway (SBP), is activated in regenerating muscle stem cells (MuSCs). Gene inactivation and metabolomics revealed that Psat1, one of the three SBP enzymes, controls MuSC activation and expansion of myogenic progenitors through production of the metabolite α-ketoglutarate (α-KG) and α-KG-generated glutamine. Psat1 ablation resulted in defective expansion of MuSCs and impaired regeneration. Psat1, α-KG, and glutamine were reduced in MuSCs of old mice. α-KG or glutamine re-established appropriate muscle regeneration of adult conditional Psat1 -/- mice and of old mice. These findings contribute insights into the metabolic role of Psat1 during muscle regeneration and suggest α-KG and glutamine as potential therapeutic interventions to ameliorate muscle regeneration during aging.

Keywords: aging; glutamine; ketoglutarate; muscle regeneration; muscle stem cells.

Age-related changes in fibroblast cells promote pancreatic cancer growth and spread

Posted by in categories: biotech/medical, life extension

Older people may be at greater risk of developing pancreatic cancer and have poorer prognoses because of age-related changes in cells in the pancreas called fibroblasts, according to research led by investigators from the Johns Hopkins Kimmel Cancer Center, the Johns Hopkins Bloomberg School of Public Health and the Bloomberg~Kimmel Institute for Cancer Immunotherapy.

The study, published online Feb. 8 in Cancer Research, provides clues as to why pancreatic cancer is more common and aggressive in older people. It may also help scientists develop new therapeutic approaches for this difficult-to-treat cancer. The study showed that aging alters fibroblasts in ways that enable them to promote pancreatic cancer tumor growth.

“Older fibroblasts release proteins that directly affect pancreatic cancer cells and ultimately lead to the growth and spread of pancreatic cancer tumors,” says the study’s lead author, Daniel Zabransky, M.D., Ph.D., assistant professor of oncology at the Johns Hopkins University School of Medicine. “The younger fibroblasts did not have these capabilities. We think this is a key reason why we see pancreatic cancer more commonly in older patients.”

Facebook Is Making Insane AI-Generated Fever Dreams Go Viral for Gullible Boomers

Posted by in categories: life extension, robotics/AI

Facebook is quickly being overrun by dubious, AI-generated junk — which is somehow attracting huge amounts of attention from its aging user base.

Worse yet, according to a new analysis by Stanford and Georgetown University researchers, first spotted by 404 Media, scammers and spammers are using this lowbrow content to grow their audiences on Facebook.

Even with the proliferation of AI image generators, the novelty has clearly yet to wear off for users on the largest social media network, a veritable social media dinosaur.

New Research: Talking Faster Is Linked to Better Brain Health As We Age

Posted by in categories: life extension, neuroscience

As we age, we might begin to observe that it takes more time to recall the exact words we want to use. This situation can raise worries about cognitive deterioration and the risk of dementia.

However, a new study by Baycrest and the University of Toronto suggests that talking speed is a more important indicator of brain health than difficulty finding words, which appears to be a normal part of aging. This is one of the first studies to look at both differences in natural speech and brain health among healthy adults.

“Our results indicate that changes in general talking speed may reflect changes in the brain,” says Dr. Jed Meltzer, Baycrest’s Canada Research Chair in Interventional Cognitive Neuroscience and the lead author on this study. “This suggests that talking speed should be tested as part of standard cognitive assessments to help clinicians detect cognitive decline faster and help older adults support their brain health as they age.”
