Innovation At The Intersection Of Cancer & Aging, Via Digital Health & Behavioral Sciences — Dr. Corinne Leach, Ph.D. American Cancer Society
Dr. Corinne Leach, PhD, MPH, MS, is a gerontologist, digital health strategist, and behavioral scientist, who serves as the Senior Principal Scientist, Behavioral Research, at the American Cancer Society (https://www.cancer.org/).
Dr. Leach, leads survivorship research on behalf of the Population Sciences group, serving as the Principal Investigator of the American Cancer Society (ACS) survivorship cohorts, and as the ACS-lead for the ACS-National Cancer Institute online self-management platform, Springboard Beyond Cancer, a novel eHealth tool that empowers cancer survivors to better manage their cancer-related symptoms, live healthier, and improve their communication skills about cancer (as well as other health conditions), during and after treatment.
Dr. Leach’s cancer survivorship research focuses in the areas of aging, cancer-related symptom assessment, and chronic disease self-management, and her research aims to improve the understanding of: behavioral factors that contribute to healthy aging and the best way to promote them, the unique experiences of older cancer survivors, such as physical late effects and psychosocial issues, and ways to improve survivors’ self-management of cancer-related issues.
Dr. Leach also studies accelerated aging after a cancer diagnosis, including the accumulation of multiple chronic conditions after a cancer diagnosis, and she evaluates the benefits of health behavior interventions, such as chronic disease self-management.
Becoming Immortal through Mind Uploading sounds like something that’ll only be possible around the 2100’s. But amazingly, a group of scientists at Nectome are working on giving us the ability to live forever inside of a computer simulation by the end of this decade for around 10000$.
Ray Kurzweil, director of engineering at Google, has long predicted that people will be able to upload their entire brains to computers and become digitally immortal by 2045. Kurzweil made this claim for many years, e.g. during his speech in 2013 at the Global Futures 2045 International Congress in New York, which claims to subscribe to a similar set of beliefs. Mind uploading has also been advocated by a number of researchers in neuroscience and artificial intelligence, such as the late Marvin Minsky.

Aging affects everybody, so it’s easy to understand why so much scientific attention is focused on studying it. Scientists in Canada now claim to have found that telomeres play a different role in cellular aging than previously thought.
One of the main points of interest in anti-aging biology are what’s known as telomeres. These are sections of “junk” DNA that form caps on the ends of chromosomes, protecting important genetic information from damage when a cell divides. But a piece of the telomere is eroded away with each cell division, and when it gets too short the cell stops dividing entirely, entering a dormant state known as senescence. The build-up of these senescent cells contributes to a range of symptoms we associate with aging, such as frailty and age-related diseases.
The implication of this model is that telomeres take on a pre-emptive protection role – they signal to cells to stop dividing as soon as one telomere wears out. But there is evidence to suggest that cell division can continue with as many as five dysfunctional telomeres.
Cryogenically frozen dead people are held preserved in a clinic at Scottsdale, Arizona in the hope that maybe someday science would be advanced enough to bring them back to life. This unique cryonics clinic is run by Alcor Life Extension Foundation, and surprisingly, many people, including some famous personalities like PayPal co-founder Peter Theil, are actually spending hundreds of thousands of dollars to have their bodies preserved here after death.
The idea of waking up in the future sounds like a great plot for a sci-fi movie or a novel but through cryonics 0 organizations like Alcor are trying to do the same in reality. Max Moore, a futurist and the former CEO of Alcor, believes that people can be rescued from death. “Our view is that when we call someone dead it’s a bit of an arbitrary line. In fact they are in need of a rescue,” he said in an interview. What’s perhaps more surprising is that Alcor is not the only cryonics clinic preserving dead bodies for revival in the future.
Discussing The Future Of “Seno-Therapeutic” Development — Dr. Judith Campisi, PhD, Professor of Biogerontology, Buck Institute for Research on Aging.
Dr. Judith Campisi, PhD (https://www.buckinstitute.org/lab/campisi-lab/) is a biochemist, cell biologist, and Professor of Biogerontology at the Buck Institute for Research on Aging.
Dr. Campisi received a PhD in biochemistry from the State University of New York at Stony Brook and completed her postdoctoral training in cell cycle regulation at the Dana-Farber Cancer Institute and Harvard Medical School. As an assistant and associate professor at the Boston University Medical School, she studied the role of cellular senescence in suppressing cancer and soon became convinced that senescent cells also contributed to aging. She joined the Lawrence Berkeley National Laboratory as a senior scientist in 1991 working with Dr. Mina Bissell. In 2,002 she started a second laboratory at the Buck Institute. At both institutions, Dr. Campisi established a broad program to understand the relationship between aging and age-related disease, with an emphasis on the interface between cancer and aging.
Dr. Campisi is a member of the National Academy of Sciences and a fellow of the American Association for the Advancement of Science.
Dr. Campisi has received numerous awards for her research, including two MERIT awards from the National Institute on Aging and awards from the AlliedSignal Corporation, Gerontological Society of America, and American Federation for Aging Research. She is a recipient of the Longevity prize from the IPSEN Foundation, the Bennett Cohen award from the University of Michigan, and the Schober award from Halle University, and she is the first recipient of the international Olav Thon Foundation prize in Natural Sciences and Medicine. Dr. Campisi currently serves on advisory committees for the Alliance for Aging Research, Progeria Research Foundation, and NIA’s Intervention Testing Program. She is also an editorial board member for more than a dozen peer-reviewed journals. Dr. Campisi is a scientific founder of Unity Biotechnology, a California-based company focused on developing senolytic therapies for age-related pathologies. She has served on the scientific advisory boards of the Geron Corporation, Sierra BioScience, and Sangamo Biosciences.

In a groundbreaking study of people living with HIV, University of Alberta researchers found that elusive white blood cells called neutrophils play a role in impaired T cell functions and counts, as well as the associated chronic inflammation that is common with the virus.
Neutrophils are a foundational part of the body’s immune system and the most abundant type of white blood cell, making up about 60 to 80 per cent of circulating immune cells in the blood. However, unlike other types of white blood cells, neutrophils are extremely short-lived and cannot be frozen and thawed like other immune cells, making them extremely difficult to examine, said study lead Shokrollah Elahi.
“Neutrophils live for hours to a day or two maximum,” Elahi said. “The body produces a lot of neutrophils, and they do their job and then they die and have to be regenerated in the bone marrow. But despite the fact that neutrophils are the most abundant white blood cells in the blood circulation, their role in the context of HIV has not been very well defined.”
In a study published in Nucleic Acids Research, the team of cancer researcher Francis Rodier, an Université de Montréal professor, shows for the first time that cellular senescence, which occurs when aging cells stop dividing, is caused by irreversible damage to the genome rather than simply by telomere erosion.
This discovery goes against the scientific model most widely adopted in the last 15 years, which is based on one principle: telomeres, caps located at the ends of chromosomes whose purpose is to protect genetic information, erode with each cell division. When they get too short, they tell the cell to stop dividing, thus preventing damage to its DNA. Made dormant, the cell enters senescence.
For this model to be valid, the inactivation of a single telomere should be sufficient to activate the senescence program. Rodier’s laboratory and many others had already observed that several dysfunctional telomeres were necessary.
A futuristic Pill will soon have the ability to fix any issue with the Human body, cure any disease and even make you live longer. This advancement in Biology is made possible with the help of Artificial Intelligence in the form of Google’s Alphafold 2.0 which solved Protein Folding and created a huge medical database of all proteins for all scientists and researchers to use for free.
Protein folding is the physical process by which a protein chain is translated to its native three-dimensional structure, typically a “folded” conformation by which the protein becomes biologically functional. People like David Sinclair are using it to increase longevity and create future medicine and pills to give human actual superpowers.
