Fear of AI in the West is misdirected

Posted by in categories: internet, life extension, robotics/AI

The fear of artificial intelligence is largely a Western phenomenon. It is virtually absent in Asia. In contrast, East Asia sees AI as an invaluable tool to relieve humans of tedious, repetitive tasks and to deal with the problems of aging societies. AI brings productivity gains comparable to the ICT (information and communications technology) revolution of the late 20th century.

China is using AI as an integral part of the Fourth Industrial Revolution, which brings together different “Industry 4.0” technologies – high-speed (fifth-generation) communications, the Internet of Things (IoT), robotics, etc. Chinese ports unload container ships in 45 minutes, a task that can take up to a week in other countries.

Today’s fear of AI has many parallels to the fear of machines at the end of the 19th century. French textile workers, fearing mechanical weaving would endanger their jobs and devalue their craft, threw their “sabots” (clogs) into weaving machines to render them inoperable. They gave us the word sabotage.

Gene Therapies for Eternal Youth

Posted by in categories: biotech/medical, life extension

Now fast forward 10 more years. That same man and his peers will have counted 70 circles round the sun. But John will remain biologically 60. At the same time, someone who is 30 years old in the year 2033 could theoretically begin the therapy at age 30, and stick at a biological age of 30 for the next 30 years, when their calendar would call them 60. That’s what gene therapies for longevity could do.


Longevity startups are riding high as a wave of gene therapies advance through clinical trials. Can they actually turn back the clock?

So far, gene therapy has been approved by the U.S. Food and Drug Administration (FDA) for only a couple of applications like rare inherited diseases and blood cancer. That said, more than 2,000 clinical trials are taking place in 2023, with 200 of them having already reached phase 3 clinical trials. A slew of upcoming gene therapies could be approved—possibly in the months to come—in the United States and Europe, targeting everything from sickle cell disease and hemophilia to metastatic skin cancer. In this future, gene therapy will be approved for everything we can imagine—and many things we can’t.

Powerful gene editing approach boosts rotifers in pantheon of laboratory animals

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

Rotifers are excellent research organisms for studying the biology of aging, DNA repair mechanisms, and other fundamental questions. Now, using an innovative application of CRISPrCas9, scientists at the Marine Biological Laboratory, Woods Hole, have devised a method for making precise, heritable changes to the rotifer genome, enabling the larger community of scientists to deploy the rotifer as a genetically tractable lab organism.

CDC detects coronavirus, HIV, hepatitis and herpes at unlicensed California lab

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

Local and federal authorities spent months investigating a warehouse in Fresno County, California, that they suspect was home to an illegal, unlicensed laboratory full of lab mice, medical waste and hazardous materials.

The Fresno County Public Health Department has been “evaluating and assessing the activities of an unlicensed laboratory” in Reedley, the health department’s assistant director, Joe Prado, said in a statement Thursday. All of the biological agents were destroyed by July 7 following a legal abatement process by the agency.

“The evaluation required coordination and collaboration with multiple federal and state agencies to determine and classify biological and chemical contents onsite, in addition to assessing jurisdictional authority under this unique situation,” Prado said.

Can senotherapeutic peptides reduce skin aging?

Posted by in categories: biotech/medical, life extension

The skin is the largest organ of the body, comprising several compartments and about 20 different cell types that are involved in various skin functions – complexity that is more than skin deep! [1] Skin aging is a multifactorial process that is impacted by several intrinsic and extrinsic factors. Constant exposure of the human skin to such stimuli impacts its function and accelerates aging resulting in dry skin, wrinkling, thinning of the epidermis, and reduced barrier integrity. While we notice most of those changes by looking in a mirror – something the cosmetics industry has leveraged to multi-billion dollar effect – older skin is more at risk of injury, less able to sense touch, heat and cold, slower to heal and more prone to cellulitis and other skin infections.

Aging is a complex and gradual process characterized by a reduction in function and reproducibility along with an increase in the incidence of degenerative diseases. Skin aging has been reported to be associated with the presence and accumulation of senescent cells. “A number of diseases that increase in older people may have a unifying underlying mechanism having to do with senescence,” says Ruth Montgomery, PhD, professor of medicine and epidemiology (microbial diseases) at Yale School of Medicine [2].

Senescent cells are those that have lost their proliferative capacity, are resistant to apoptosis, and secrete factors that can cause tissue deterioration and inflammation [3]. These factors are termed senescence-associated secretory phenotype (SASP) and can lead to extracellular matrix (ECM) deposition, impact epidermal stem cell renewal and worsen melanin synthesis.

Multi-omic rejuvenation and life span extension on exposure to youthful circulation

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

Heterochronic parabiosis ameliorates age-related diseases in mice, but how it affects epigenetic aging and long-term health was not known. Here, the authors show that in mice exposure to young circulation leads to reduced epigenetic aging, an effect that persists for several months after removing the youthful circulation.

Matters Arising: The Information Theory of Aging Has Not Been Tested

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

Yang and co-workers state that “using inducible changes to the epigenome, we find that the act of faithful DNA repair advances aging at physiological, cognitive, and molecular levels, including erosion of the epigenetic landscape, cellular exdifferentiation, senescence, and advancement of the DNA methylation clock, which can be reversed by OSK-mediated rejuvenation. These data are consistent with the information theory of aging, which states that a loss of epigenetic information is a reversible cause of aging.” There is extensive evidence that the key reagent, restriction endonuclease I-PpoI, is cytotoxic. Moreover, the corresponding author published two papers—neither cited—showing that I-PpoI targeted to specific cell types causes a p53 response and cell elimination within a month. Despite globally inducing I-PpoI activation for seven times as long as required to induce a progeric effect, no analysis of mice during this critical window was presented. No significant conclusion of Yang was demonstrated.

Storing dead people at —196°C

In Switzerland, there’s a new cryonics company: and they invited me to have a look around. I had questions: legal, practical, and ethical, and I want to be clear: this is not an endorsement. I just wasn’t going to turn down that invitation. ■ Tomorrow Bio: https://www.tomorrow.bio/

How immunity contributes to aging and neurodegeneration

Posted by in categories: biotech/medical, life extension

As we age, our bodies undergo various changes that can impact our overall health and make us more susceptible to diseases. One common factor in the aging process is low-grade inflammation, which contributes to age-related decline and impairment. However, the precise pathways responsible for this inflammation and their impact on natural aging have remained elusive until now.

A new study led by Andrea Ablasser at EPFL now shows that a molecular signaling pathway called cGAS/STING plays a critical role in driving and functional decline during aging. By blocking the STING protein, the researchers were able to suppress in senescent cells and tissues, leading to improvements in tissue function.

The findings are published in the journal Nature.
