Recharging the powerhouse of the cell

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

When we need to recharge, we might take a vacation or relax at the spa. But what if we could recharge at the cellular level, fighting against aging and disease with the microscopic building blocks that make up the human body?

The ability to recharge cells diminishes as humans age or face diseases. Mitochondria, often called the powerhouse of the cell, are central to energy production. When mitochondrial function declines, it leads to fatigue, tissue degeneration, and accelerated aging. Activities that once required minimal recovery now take far longer, highlighting the role that these organelles play in maintaining vitality and overall health.

While current treatments for ailments related to aging and diseases like type 2 diabetes, Alzheimer’s, and Parkinson’s focus on managing symptoms, Texas A&M researchers have taken a new approach to fight the battle at the source: recharging mitochondrial power through nanotechnology.

Why some organs age faster than others: Scientists discover hidden mutations in non-coding DNA

Posted by in categories: biotech/medical, life extension

The accumulation of mutations in DNA is often mentioned as an explanation for the aging process, but it remains just one hypothesis among many. A team from the University of Geneva (UNIGE), in collaboration with the Inselspital, University Hospital of Bern and the University of Bern (UNIBE), has identified a mechanism that explains why certain organs, such as the liver, age more rapidly than others.

The mechanism reveals that damages to non-coding DNA, which are often hidden, accumulate more in slowly proliferating tissues, such as those of the liver or kidneys. Unlike in organs that regenerate frequently, these damages remain undetected for a long time and prevent . These results, published in the journal Cell, open new avenues for understanding cellular aging and potentially slowing it down.

Our organs and tissues do not all age at the same rate. Aging, marked by an increase in —cells that are unable to divide and have lost their functions—affects the liver or kidneys more rapidly than the skin or intestine.

Japan’s elderly population rises to record 36.25 million

Posted by in categories: government, life extension

The senior population of Japan aswell as the global population needs to consider taking high dosages of nad plus as it has essentially proven that it can reverse the hallmarks of aging.


Japanese aged 65 or older now account for nearly 30 percent of the population, government data shows.

Archaeologists Discovered an Ancient Immortality Potion That Exposes the Cost of Chasing Eternal Life

Posted by in categories: biotech/medical, life extension

Humans have been trying to cheat death for thousands of years. Myths about elixirs promising immortality span various cultures, as do real concoctions that often did more harm than good. One of the most misguided attempts at creating a potion for immortality involved the first emperor of China and mercury pills. In his obsession with finding a formula that would grant him eternal life, Qin Shi Huang downed mercury and other toxic substances nearly two millennia ago, believing his alchemists had hit upon the perfect magical tonic. Unsurprisingly, he died prematurely at age 49.

Archeologists have discovered another 2,000-year-old “elixir for immortality” that sheds light on the true cost of chasing down eternal life.

While excavating the tomb of a Western Han noble family in China’s Henan province in 2018, researchers unearthed a bronze pot. At first, the team thought the liquid inside was wine, but more recently determined that it was an alchemist’s formulation: a yellow liquid containing potassium nitrate and alunite. These two ingredients are cited in ancient Taoist texts as ingredients for immortality. Potassium nitrate is an inorganic salt used today as a natural source of nitrate, and is a useful ingredient in food preservatives, fertilizer, and fireworks. Alunite is a mineral that forms in volcanic or sedimentary environments when sulfur-rich minerals oxidize. It has historically been used to make alum, which is important for water purification, tanning, and dyeing.

Eggs from older mice regain youth when grown in young cells

Posted by in category: life extension

Growing immature eggs from old mice in the ovarian structures of young mice can reverse signs of ageing in the eggs1.

“Think of this as a five-star anti-ageing spa for the old egg,” says Rong Li, a cell biologist at the National University of Singapore (NUS), who co-authored a study describing the results.

When the rejuvenated eggs were fertilized, the resulting embryos were almost four times more likely to give rise to healthy pups than the eggs that matured in the old environment. The results are published in Nature Aging today.

Decoding Aging: The Science Of Cellular Rejuvenation With Dr. Vittorio Sebastiano

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

It was a career-defining (and perhaps life changing) moment when Dr. Vittorio Sebastiano, a reproductive biologist by training, realized that because we are able to create life, that same body of information could be harnessed to create youth — that is, radically reverse our biological aging process to a younger time point without losing cellular identity.

In 2014, he and his lab began unpacking this epiphany. They made the radical decision to conduct their investigations in human cells and tissue rather than in rodents, with the expectation that such a start would be a better bridge to human clinical trials.

A comprehensive map of the aging blood methylome in humans

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

During aging, the human methylome undergoes both differential and variable shifts, accompanied by increased entropy. The distinction between variably methylated positions (VMPs) and differentially methylated positions (DMPs), their contribution to epigenetic age, and the role of cell type heterogeneity remain unclear.

We conduct a comprehensive analysis of 32,000 human blood methylomes from 56 datasets (age range = 6–101 years). We find a significant proportion of the blood methylome that is differentially methylated with age (48% DMPs; FDR 0.005) and variably methylated with age (37% VMPs; FDR 0.005), with considerable overlap between the two groups (59% of DMPs are VMPs). Bivalent and Polycomb regions become increasingly methylated and divergent between individuals, while quiescent regions lose methylation more uniformly. Both chronological and biological clocks, but not pace-of-aging clocks, show a strong enrichment for CpGs undergoing both mean and variance changes during aging. The accumulation of DMPs shifting towards a methylation fraction of 50% drives the increase in entropy, smoothening the epigenetic landscape. However, approximately a quarter of DMPs exhibit anti-entropic effects, opposing this direction of change.

Cleaning up the aging brain

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

Alzheimer’s, Parkinson’s, and other neurological disorders can be seen as “dirty brain” diseases, where the brain struggles to clear out harmful waste. Aging is a key risk factor because, as we grow older, our brain’s ability to remove toxic buildup slows down. However, new research in mice demonstrates that it’s possible to reverse age-related effects and restore the brain’s waste-clearing process.

“This research shows that restoring cervical lymph vessel function can substantially rescue the slower removal of waste from the brain associated with age,” says Douglas Kelley, a professor of mechanical engineering at the University of Rochester. “Moreover, this was accomplished with a drug already being used clinically, offering a potential treatment strategy.”

Kelley is one of the lead authors of the study, which appears in the journal Nature Aging, along with Maiken Nedergaard, codirector the University’s Center for Translational Neuromedicine. The study is one of many collaborations carried out by researchers at Rochester’s Hajim School of Engineering & Applied Sciences and the Medical Center.
