The Failures and Opportunities of Immortality

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

Steven Parton [00:00:37] Hello everyone. My name is Steven Parton and you are listening to the feedback loop on Singularity Radio. This week our guest is business and technology reporter Peter Ward. Earlier this year, Peter released his book The Price of Immortality The Race to Live Forever, where he investigates the many movements and organizations that are seeking to increase the human lifespan from the Church of Perpetual Life in Florida to some of the biggest tech giants in Silicon Valley. In this episode, we explore Peter’s findings, which takes us on a tour from cryogenics to mind uploading from supplements to gene editing and much more. Along the way, we discuss the details of how one might actually achieve immortality, talking about senescent cells and telomeres. Discussing whether it’s better to live healthy than to live long. We also discuss the scams and failures that seem to dominate the longevity space, as well as the efforts that seem the most promising. And now, since we’re on the topic of discussing how precious life is, are waste no more of your precious time? So everyone, please welcome to the feedback loop. Peter Ward. Well then, Peter, thanks for joining me. I think the best place to start is in April of this year. You released a book called The Price of Immortality The Race to Live Forever and where I love to start with anyone who’s written a book is just hearing about your motivations for the book. Why did you decide that this was a topic worth exploring?

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 Undetectable Mechanism Of Antibiotic-Resistant Bacteria Discovered

Posted by in category: biotech/medical

A new mechanism that enables bacteria to form resistance to antibiotics has been discovered in a recent study conducted by researchers in Perth, Australia. In a process currently undetectable using traditional laboratory testing methods, the team observed the bacteria group A Streptococcus – the cause of strep throat – absorbing nutrients from the host organism that, in turn, enable them to bypass antibiotic treatment.

For bacteria to grow and multiply, they produce folates. Bacteriostatic antibiotics work to stop the bacteria’s ability to produce these folates, thus disabling their ability to multiply. The group A Streptococcus bacteria observed in the study, however, were seen to be using folates from the host when their own folate production was inhibited, causing a resistance to treatment from bacteriostatic antibiotics and likely making any infection worse.

The human body cannot become resistant to antimicrobial treatments. Rather, antimicrobial resistance (AMR) refers to bacteria or fungi’s resistance to antibiotics or antifungals, respectively. AMR is thought to pose a serious and rapidly growing threat to society.

Smart stem cells made from fat have the power to heal

Posted by in category: biotech/medical

New smart stem cells show a promising power to heal.

Researchers have reprogrammed human fat cells into adaptive smart stem cells that can lie dormant in the body until they are needed to heal various tissues. They demonstrated the cells’ effectiveness at healing damaged tissue in a mouse study.

To create the smart stem cells, the team from UNSW Sydney exposed human fat cells to a compound mixture. After about three and a half weeks, the cells lost their original identity and began acting like stem cells, or iMS (induced multipotent stem cells).

Nanotech strategy shows promise for treating autoimmune disease

Posted by in categories: biotech/medical, chemistry, nanotechnology

Scientists at Scripps Research have reported success in initial tests of a new, nanotech-based strategy against autoimmune diseases.

The scientists, who reported their results in ACS Nano, engineered cell-like “” that target only the driving an autoimmune reaction, leaving the rest of the immune system intact and healthy. The nanoparticles greatly delayed, and in some animals even prevented, in a mouse model of arthritis.

“The potential advantage of this approach is that it would enable safe, long-term treatment for where the immune system attacks its own tissues or organs—using a method that won’t cause broad immune suppression, as current treatments do,” says study senior author James Paulson, Ph.D., Cecil H. and Ida M. Green Chair of Chemistry in the Department of Molecular Medicine at Scripps Research.

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].

Cancer Weakness Discovered: New Method Pushes Cancer Cells Into Remission

Posted by in categories: biotech/medical, genetics

Cancer cells delete DNA

DNA, or deoxyribonucleic acid, is a molecule composed of two long strands of nucleotides that coil around each other to form a double helix. It is the hereditary material in humans and almost all other organisms that carries genetic instructions for development, functioning, growth, and reproduction. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

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.

MRNA vaccines offer one-two punch to combat malaria

Posted by in categories: biotech/medical, health

Malaria is found in more than 90 countries around the world, causing 241 million cases and an estimated 627,000 deaths every year. Vaccines are one intervention that could help eliminate this deadly disease, yet a highly effective vaccine remains elusive. Recent technological advances in vaccine development–such as the mRNA vaccines for SARS-CoV2–could lead to a new generation of malaria vaccines.

Now, a research team led by George Washington University has developed two mRNA candidates that are highly effective in reducing both and transmission. The team also found that the two experimental vaccines induced a powerful immune response regardless of whether they were given individually or in combination. The study was published today in npj Vaccines, an open-access that is part of the Nature Portfolio.

“Malaria elimination will not happen overnight but such vaccines could potentially banish from many parts of the world,” Nirbhay Kumar, a professor of global health at the George Washington University Milken Institute School of Public Health, said. “The mRNA vaccine technology can really be a game changer. We saw how successful this technology was in terms of fighting COVID and for this study we adapted it and used it to develop tools to combat malaria.”
