The Formula of Immortality

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

Dreaming about Immortality has a long history, almost as long as the failed quests to achieve it. And during all these years and years, the solutions for achieving immortality can fall in several categories. The first is to take some kind of “magic pill” – be it the fountain of youth, the elixir of life, the holy grail, till modern medicine of genetic engineering. After the magic “pills” proved to be a failure, the second attempt was through more creative endeavours, such as building a monastery, a temple, making a sculpture or painting, till nowadays when we talk about digital immortality and I guess soon about virtual immortality. And, of course, there were always the “party-spoilers”, the ones asking: why to be Immortal?

Humanity has changed in many ways, but the hope of the dream of Immortality remained and generation after generation, trying to find it in different ways or forms. So, keep with us as we travel alongside the deepest human dream, to see all (the failed) trials.

New AI-enabled study unravels the principles of aging

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

New work from Gero, conducted in collaboration with researchers from Roswell Park Comprehensive Cancer Center and Genome Protection Inc. and published in Nature Communications, demonstrates the power of AI combined with analytical tools borrowed from the physics of complex systems to provide insights into the nature of aging, resilience and future medical interventions for age-related diseases including cancer.

Longevity. Technology: Modern AI systems exhibit superhuman-level performance in medical diagnostics applications, such as identifying cancer on MRI scans. This time, the researchers took one step further and used AI to figure out principles that describe how the biological process of aging unfolds in time.

The researchers trained an AI algorithm on a large dataset composed of multiple blood tests taken along the life course of tens of thousands of aging mice to predict the future health state of an animal from its current state. The artificial neural network precisely projected the health condition of an aging mouse with the help of a single variable, which was termed dynamic frailty indicator (dFI) that accurately characterises the damage that an animal accumulates throughout life [1].

Scientists discover a new mechanism to generate cartilage cells

Posted by in categories: biotech/medical, life extension

As any weekend warrior understands, cartilage injuries to joints such as knees, shoulders, and hips can prove extremely painful and debilitating. In addition, conditions that cause cartilage degeneration, like arthritis and temporomandibular joint disorder (TMJ), affect 350 million people in the world and cost the U.S. public health system more than $303 billion every year. Patients suffering from these conditions experience increased pain and discomfort over time.

However, an exciting study led by faculty at The Forsyth Institute suggests new strategies for making with huge implications in regenerative medicine for future cartilage injuries and degeneration treatments. In a paper, entitled “GATA3 mediates nonclassical β-catenin signaling in skeletal determination and ectopic chondrogenesis,” co-first authors Takamitsu Maruyama and Daigaku Hasegawa, and senior author Wei Hsu, describe two breakthrough discoveries, including a new understanding of a multifaced protein called β-catenin.

Dr. Hsu is a senior scientist at the Forsyth Insitute and a Professor of Developmental Biology at Harvard University. He is also an affiliate faculty member of the Harvard Stem Cell Institute. Other members conducting the study included Swiss scientists Tomas Valenta and Konrad Basler, and Canadian scientists Jody Haigh and Maxime Bouchard. The study appears in the most recent issue of Science Advances.

Sexual-lineage-specific DNA methylation regulates meiosis in Arabidopsis

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

Year 2017 This is essentially the mechanism for plant immortality.


RNA-directed DNA methylation (RdDM) activity in the Arabidopsis thaliana male sexual lineage that regulates gene expression in meiocytes. Loss of sexual-lineage-specific RdDM causes mis-splicing of the MPS1 gene (also known as PRD2), thereby disrupting meiosis. Our results establish a regulatory paradigm in which de novo methylation creates a cell-lineage-specific epigenetic signature that controls gene expression and contributes to cellular function in flowering plants.

How tardigrades come back from the dead

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

Year 2017 Basically the tardigrade is the most promising set of genes on any creature due to many types of survival genes like going years without food or even genes for radiation resistance which could be used in crispr to augment human genes.


Tardigrades — aka water bears or moss piglets — are perhaps the most resilient creatures on the planet, able to survive complete dehydration, space vacuum and being frozen. However, only recently have scientists begun to unravel the genes that underpin the tardigrade’s biological superpowers. “They’re 0.2mm to 1mm in length and despite being so small they are able to do all these things we cannot,” says Mark Blaxter, a biologist at the University of Edinburgh who has been studying tardigrades for 20 years. “In their DNA, they hold a cornucopia of secrets.”

With Kazurahu Arakawa, from the University of Keio, Japan, Blaxter recently analysed the first true tardigrade genome. The results, published today in the open access journal PLOS Biology, are a first step towards explaining the genetics underpinning the tardigrade’s extraordinary resilience and to pinpoint its place within the evolutionary tree of life. We spoke to Blaxter about his new research and his fascination for this remarkable little animal.

What Happens When Everyone Realises We Can Live Much Longer? We May Find Out As Soon As 2025

Posted by in categories: biotech/medical, life extension

Let’s not just cure cancer: let’s cure aging One of the most exciting areas of modern scientific research is the investigation of the causes and cures for aging. Not individual diseases like cancer and heart disease, but the processes which make us elderly and frail, and which thereby make us more susceptible to these diseases.

New small molecule drug for lowering cholesterol

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

After statins, the next leading class of medications for managing cholesterol are PCSK9 inhibitors. These highly effective agents help the body pull excess cholesterol from the blood, but unlike statins, which are available as oral agents, PCSK9 inhibitors can only be administered as injections, creating barriers to their use.

Longevity. Technology: Having high cholesterol can increase the risk of heart and circulatory diseases such as heart attack, stroke and vascular dementia, but a new study from investigators at University Hospitals (UH) and Case Western Reserve University School of Medicine details an orally administered small-molecule drug that reduces PCSK9 levels and lowers cholesterol in animal models by 70%. Published in Cell Reports, the findings represent a previously unrecognised strategy for managing cholesterol and may also impact cancer treatments.

Cardiovascular disease ranking as the world’s number one killer, so it’s no surprise that a significant amount of research into potential therapeutic options is ongoing; just last week we looked at Cyclarity’s rationally-designed cyclodextrin molecules that remove arterial plaque by clearing the non-degradable oxidised cholesterol and which can be used in conjunction with statins for a broad-spectrum approach. Our report into Cyclarity’s new platform comes out next week, so stay tuned!

Old skin cells reprogrammed to regain youthful function

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

Research from the Babraham Institute has developed a method to “time jump” human skin cells by 30 years, turning back the aging clock for cells without losing their specialized function. Work by researchers in the Institute’s Epigenetics research program has been able to partly restore the function of older cells, as well as rejuvenating the molecular measures of biological age. The research is published today in the journal eLife, and while this topic is still at an early stage of exploration, it could revolutionize regenerative medicine.

What is regenerative medicine?

As we age, our cells’ ability to function declines and the accumulates marks of aging. Regenerative biology aims to repair or replace cells including old ones. One of the most important tools in regenerative biology is our ability to create “induced” stem cells. The process is a result of several steps, each erasing some of the marks that make cells specialized. In theory, these stem cells have the potential to become any cell type, but scientists aren’t yet able to reliably recreate the conditions to re-differentiate stem cells into all cell types.
