People with rare disorders that cause shortened telomeres—protective caps that sit at the end of chromosomes—may be more likely to have blood cancers such as leukemia or myelodyplastic syndrome. Now, Johns Hopkins Medicine scientists have discovered several “self-correcting” genetic mutations in bone marrow that may protect such patients from these cancers.
Summary: Researchers have identified 2,000 genes in humans linked to longevity. The genes are associated with biological mechanisms that drive the prolongation of life in mammals, including DNA repair, coagulation, and immune response.

What determines the life expectancy of each species? This is a fundamental and highly complex question that has intrigued the field of research throughout history. From the evolutionary point of view, the major cause of these differences between species lies in their ecological adaptations. For example, life expectancy is longer in species adapted to living in trees, underground, or with large body mass, since all these adaptations reduce mortality by predation.
Youthereum talking about rejuvenation, funding, there is a history lesson here but the modern look starts at 38:01.
My overview of the history of partial reprogramming — a novel approach to epigenetic rejuvenation that uses short bursts of Yamanaka factors expression to periodically roll back the epigenetic state of cells to a younger pattern.
“After demonstrating that cultured meat can reach cost parity faster than the market anticipated, this production facility is the real game-changer,” said Yaakov Nahmias, Future Meat Technologies founder and chief scientific officer, in a press release. “This facility demonstrates our proprietary media rejuvenation technology in scale, allowing us to reach production densities 10-times higher than the industrial standard.”
Cultured meat is made by extracting cells from animal tissue and giving them nutrients, oxygen, and moisture while keeping them at the same temperature they’d be at inside an animal’s body. The cells divide and multiply then start to mature, with muscle cells joining to create muscle fibers and fat cells producing lipids. The resulting nuggets of meat can be used to make processed products like burgers or sausages. Structured cuts of meat with blood vessels and connective tissue, like steak or chicken breast, require scaffolds, and researchers are creating these with biomaterials, like cellulose from plants. Companies are working on several varieties of more elaborate cultured products, from bacon to salmon.
Jeff Bezos, the world richest man is investing in anti-ageing technology that could extend the average human lifespan by up to 50 years, WITHIN NIGERIA learnt.
It was also learnt that Jeff Bezos is one of the several billionaire investors in Altos Labs, a Silicon Valley tech firm working on experimental – and potentially dangerous – new life extension technologies.
This is an excerpt I made from a conversation between Sergey Young and David Sinclair. Along it, they share their impressions as to how much Longevity science have progressed during the last few years.
The link to the entire conversation and the Q&As from the audience that was watching the webinar is in the description of the video.
Dr. The book launch will happen on September 4th, at 3 p.m. (Pacific Time) in Book Passage Ferry Building Store in San Francisco, California! Please come to have an in-person chat with Dr. Katcher.
Dr. Harold Katcher is one of the discoverers of the human breast cancer gene (BRCA1), and has thousands of citations in the scientific literature, with publications ranging from protein structure to bacteriology, biotechnology, bioinformatics and biochemistry. He was the Academic Director for Natural Sciences for the Asian Division of the University of Maryland Global Campus, and nowadays is Chief Scientific Officer at Yuvan Research Inc., which is working on the development of rejuvenation treatments.
She’s among a growing number of “grandfluencers,” folks 70 and up who have amassed substantial followings on social media with the help of decades-younger fans.
Joan MacDonald’s health was in shambles at age 71.
The late 21st century belongs to Superhumans. Technological progress in the field of medicine through gene editing tools like CRISPR is going to revolutionize what it means to be human. The age of Superhumans is portrayed in many science fiction movies, but for the first time in our species history, radically altering our genome is going to be possible through the methods and tools of science.
The gene-editing tool CRISPR, short for clustered regularly interspaced short palindromic repeats, could help us to reprogram life. It gives scientists more power and precision than they have ever had to alter human DNA.
