Three doctoral candidates from Stanford University have jointly exposed the "stem cell black market" in the United States to the public media. Their goal is to minimize the harm caused by unregulated stem cell therapies. They are Karen M. Wai, MD, Theodore Leng, MD, MS, and Jeffrey Goldberg, MD, PhD, all from the Stanford University School of Medicine, Palo Alto, California.
In fact, I believe that the United States has long ceased to be the powerhouse it was during and after the Reagan presidency. Therefore, I think there is no significant difference between the United States and China in terms of public health safety, such as the proliferation of rogue stem cell clinics.

Chinese scientists have discovered that the activation of endogenous viral elements in the human genome is a key factor in inducing cellular and organ aging. They cultured and screened millions of human cells, validating dozens of previously undiscovered genes that promote cellular aging from over 20,000 human genes. Through repeated screening, they ultimately identified a novel human pro-aging gene named KAT7. Experiments confirmed that partially inactivating this gene in the livers of elderly mice allowed 81% of the mice to live beyond 130 weeks, which is approximately equivalent to 80 years in human age.

The journal Nature simultaneously published two papers from Xiamen University. They found that a metabolite called lithocholic acid (LCA) plays a key role in the anti-aging effects of "caloric restriction." This discovery suggests that by supplementing with lithocholic acid, one may achieve the "anti-aging" benefits of caloric restriction without having to give up delicious food or subject oneself to hunger.

I tried searching for Lithocholic acid to purchase but can't find any venders . Anyone know where it can be purchased ?

Exogenous LCA has not been proven to be safe for humans and further research is needed. The main value of these papers is the understanding of the AMPK pathway.Its value is not to extend lifespan, and the AMPK pathway itself is not a pathway for extending lifespan

If humanity solves cancer, average life expectancy will significantly increase. This is because the two major causes of human death are cancer and cardiovascular diseases. Particularly in the GLP-1 era, cancer will become the primary cause of death.

This article explains that everyone's response to medications can vary significantly; what is beneficial for one person may be harmful to another. Similarly, the same anti-aging treatment can have different effects on different individuals. Therefore, a personalized approach to anti-aging is the most optimal solution.

Korean researchers figured out a way to throw a few genetic switches to cause the cancer cells to revert back to a healthy state. The technique could have major implications in the way we approach cancer treatment.
Just like the OSKM/OSK factors used in cellular reprogramming.These regulators are known as MYB, HDAC2, and FOXA2 and when they were suppressed in colon cancer cells, the cells switched back to a normal-like state, removing the cancer threat without destroying any cellular material.

The U.S. Preventive Services Task Force released updated draft recommendations on December 17, revising its 2018 guidance on vitamin D and calcium supplementation for older adults. The recommendations advise generally healthy older adults to avoid using vitamin D and calcium supplements to prevent falls and fractures. According to the independent panel of experts, while these essential nutrients are important for overall health, there is not enough evidence to suggest a net benefit for these endpoints, and supplementation may be associated with the risk of developing kidney stones.

The average life expectancy for Chinese men in 2024 is 69.9 years, and for Chinese women, it is 78.5 years.The average life expectancy of Chinese men in 2023 is 73.64 years old. 69.9 is a very small data; I know the average life expectancy of Americans is around 80 years old."

In 2024, the Center for Drug Evaluation and Research (CDER) of the US Food and Drug Administration (FDA) approved a total of 50 new drugs, including 34 new molecular entities and 16 biologics. Among the new molecular entities, small molecules predominated, accounting for about 91% (31), with the remainder consisting of nucleic acid and peptide drugs; among the biologics, 81% were antibody-based (10 monoclonal antibodies and 3 bispecific antibodies), with the rest being fusion proteins and Type A botulinum toxin. It appears that small molecules are still the main force in anti-aging efforts.

President Trump wants to annex Canada, the Gulf of Mexico, Greenland, and the Panama Canal to the United States, and I fully support this move. In fact, if it were possible to include China and other countries around the world into the United States, forming a single nation on Earth, that would be even better. This would eliminate many barriers for the anti-aging geek community, including language barriers, currency obstacles, cultural habits, ways of thinking, and educational levels. By creating a specialized anti-aging knowledge platform（http://longevitydiary.com）, we could use just one language instead of the current one that Chinese geeks and Chinese anti-aging experts can understand.

On January 6th, the United States reported its first death from the avian influenza virus (H5N1). Although no human-to-human transmission has been detected, it is crucial to be vigilant about potential viral mutations. We are currently in an era prone to viral outbreaks for two main reasons: one is natural factors, as viruses periodically emerge that can influence human DNA and drive evolution; the other is human factors, with the novel coronavirus being a coronavirus engineered from HIV. In the future, viruses may become the third leading cause of death for humans. The United States has banned TikTok, and the confrontation between the U.S. and China is intensifying. Despite issues with China's system and bureaucracy, it is the ordinary Chinese people who are affected by this confrontation, while some high-ranking Chinese individuals actually hold U.S. citizenship(most CBC is CBA). We hope that the confrontation between China and the U.S. does not affect humanity's pursuit of combating aging.

A study published in Cell Metabolism magazine indicates that exosomes rich in miR-302b, known as hESC-Exos, can reverse the proliferative stagnation of senescent cells, promote cellular rejuvenation, and restore vitality to aged mice. The research found that miR-302b, by targeting Cdkn1a and Ccng2, restores the expression of cell cycle-related genes, increases cell division, and improves the physiological functions and appearance of aged mice. Long-term delivery of miR-302b can extend the lifespan of mice, ameliorate signs of aging, without increasing the burden of tumors or diseases, effectively slowing down the aging process.

A study published in a Nature journal has indicated that the metabolic product of gut microbes — phenylacetylglutamine (PAGln) — increases with the age of the host and accelerates the aging process of the host. The research found that PAGln activates the adrenergic receptor-AMPK signaling pathway, increases the level of reactive oxygen species (ROS), mediates DNA damage, and leads to cellular senescence. The researchers proposed that the use of adrenergic receptor blockers (carvedilol) and Bcl-2 inhibitors (ABT263) can counteract PAGln-induced cellular aging.
