Doctors, apps and artificial intelligence — The future of medicine

Artificial intelligence is changing health care. It promises better diagnoses and fewer mistakes and all in less time. While some associate AI with a frightening dystopian future, many doctors see it as a source of support.

To help them care for patients, doctors are programming apps and supplying AI with data. At Berlin’s Charité hospital, Professor Surjo Soekadar is researching how neurotechnology might support paralysis patients in their everyday lives — for example, via assistance systems that are controlled via their thoughts.

This could offer hope to people like Guido Schule and Anne Nitzer had a stroke shortly after the birth of her second child and has been unable to move or speak since then — even though she is fully conscious.

At Vienna General Hospital (AKH) Professor Ursula Schmidt-Erfurth has already developed an AI-based diagnostic tool that has been licensed for use. Nowadays, she is researching how AI could improve both the diagnosis and the treatment of age-related macular degeneration (AMD). This chronic eye disease can lead to loss of vision — even with treatment. This is a fate that Oskar Zlamala could face. But since the retiree began treatment at the AKH Vienna, he is hoping that it might be possible to halt the progression of his illness.

Computer science experts and medics are also working together to help the Essen University Hospital go digital. Dr. Felix Nensa and Professor Arzu Oezcelik are improving care for transplant patients with the help of artificial intelligence. AI can calculate the size of organs, like the liver, for example, much more precisely and more quickly than people — and thereby improve outcomes and the safety of the procedure.

Turning Back the Clock: Surgical Procedure Slows Cellular Aging and Extends Lifespan by up to 10%

A process of surgically joining the circulatory systems of a young and old mouse has been found to slow aging at a cellular level and extend the older animal’s life by as much as 10%.

Recently published in Nature Aging, a study led by researchers from Duke Health discovered the longer the animals shared circulation, the longer the anti-aging benefits lasted once the two were no longer connected.

The findings suggest that the young benefit from a cocktail of components and chemicals in their blood that contribute to vitality, and these factors could potentially be isolated as therapies to speed healing, rejuvenate the body, and add years to an older individual’s life.

Ray Kurzweil Wants To Put Nanobots In Our Bloodstream

Would you want to live forever? On this episode, Neil deGrasse Tyson and author, inventor, and futurist Ray Kurzweil discuss immortality, longevity escape velocity, the singularity, and the future of technology. What will life be like in 10 years?

Could we upload our brain to the cloud? We explore the merger of humans with machines and how we are already doing it. Could nanobots someday flow through our bloodstreams? Learn about the exponential growth of computation and what future computing power will look like.

When will computers pass the Turing test? Learn why the singularity is nearer and how to think exponentially about the world. Are things getting worse? We go through why things might not be as bad as they seem. What are the consequences of having a longer lifetime? Will we deplete resources?

Will there be a class divide between people able to access longer lifespans? What sort of jobs would people have in the future? Explore what artificial intelligence has in store for us. What happens if AI achieves consciousness? We discuss the definition of intelligence and whether there will be a day when there is nothing left for humans to do. Will we ever see this advancement ending?

Thanks to our Patrons Johan Svensson, Galen J., Kellen Bolander, Sunshine, and Brian White for supporting us this week.

New Yale Initiative Looks Beyond Life Span to Increase Years of Health

Aging is a major risk factor for most chronic conditions, evidence shows, yet much of current research focuses on addressing specific diseases. The new translational geroscience initiative at Yale School of Medicine (YSM) seeks to change that approach by studying the effects of aging on various ailments.

“Yale School of Medicine has a long legacy in studying aging, but with this new initiative we are bolstering our ability to delineate basic mechanisms of healthy and accelerated aging,” said Nancy J. Brown, MD, Jean and David W. Wallace Dean of the Yale School of Medicine and C.N.H. Long Professor of Internal Medicine.

The mechanisms underlying the aging process are often also driving the development and progression of chronic conditions, explains Thomas Gill, MD, Humana Foundation Professor of Medicine (Geriatrics) and professor of epidemiology, Yale School of Public Health, and of investigative medicine at YSM, who leads the Yale Pepper Older Americans Independence Center.

Longitudinal analysis of blood markers reveals progressive loss of resilience and predicts ultimate human lifespan limit

150 YEARS MAXIMUM BIOLOGICAL AGE — “We observed, that the age-dependent population DOSI distribution broadening could be explained by a progressive loss of physiological resilience measured by the DOSI auto-correlation time. Extrapolation of this trend suggested that DOSI recovery time and variance would simultaneously diverge at a critical point of 120 − 150 years of age corresponding to a complete loss of resilience. The observation was immediately confirmed by the independent analysis of correlation properties of intraday physical activity levels fluctuations collected by wearable devices. We conclude that the criticality resulting in the end of life is an intrinsic biological property of an organism that is independent of stress factors and signifies a fundamental or absolute limit of human lifespan.”

We investigated the dynamic properties of the organism state fluctuations along individual aging trajectories in a large longitudinal database of CBC measurements from a consumer diagnostics laboratory. To simplify the analysis, we used a log-linear mortality estimate from the CBC variables as a single quantitative measure of aging process, henceforth referred to as dynamic organism state index (DOSI). We observed, that the age-dependent population DOSI distribution broadening could be explained by a progressive loss of physiological resilience measured by the DOSI auto-correlation time. Extrapolation of this trend suggested that DOSI recovery time and variance would simultaneously diverge at a critical point of 120 − 150 years of age corresponding to a complete loss of resilience.

Cell biologists identify new organelle present in mammalian cells made of rings of DNA

Researchers at ETH Zurich recently identified a previously unknown compartment in mammalian cells. They have named it the exclusome. It is made up of DNA rings known as plasmids. The researchers have published details of their discovery in the journal Molecular Biology of the Cell.

The new compartment is in the cell plasma; it is previously uncharacterized in the literature. It is exceptional because eukaryotic cells (cells with nuclei) usually keep most of their DNA in the , where it is organized into chromosomes.

Some of the plasmids that end up in the exclusome originate from outside the cell, while others—known as telomeric rings—come from the capped ends of chromosomes, the telomeres. Particularly in certain , the ones from the telomeres are regularly pinched off and joined together to form rings. However, these don’t contain the blueprints for proteins.

Targeting A $2 Dose AGING REVERSAL Therapy For Everyone

George Church at his most optimistic. June 1, 2022.

Dr George Church talks about combination therapies for age reversal, recently published papers from his lab and expresses his wish on developing inexpensive gene therapies like vaccine that can be equitably distributed to human.

Dr George Church is the Robert Winthrop Professor of Genetics at Harvard Medical School, a Professor of Health Sciences and Technology at Harvard and the Massachusetts Institute of Technology (MIT), and a core faculty member of the Wyss Institute.

Same as Dr David Sinclair, Dr George Church currently runs the Church Lab at Harvard Medical School. Both labs collaborate many projects together especially on age reversal topics. Dr Church also directs the Personal Genome Project, a long-term cohort study that allows scientists to connect human genetic information (human DNA sequence, gene expression, associated microbial sequence data, and more) with human trait information (medical information, biospecimens, and physical traits) and environmental exposures.

Australian Seaweed Boosts Collagen Levels in Human-Like Skin Cells in The Lab

If you believe the headlines, seaweeds can do almost anything from storing tons of carbon and stopping cows from belching methane, to making biofuels and renewable plastics – all while sustaining vibrant coastal ecosystems and feeding communities.

Add to that list their potential wound-healing properties and possible anti-aging effects, and it’s no wonder the seaweed farming industry is booming.

A new study adds to that fanfare, with lab experiments based on human-like skin cells revealing extracts from two brown seaweeds can inhibit reactions linked to skin aging and boost collagen levels.

11 Best Biological Age Tests for 2024

Do you use biological age tests to quantify your fitness goals? I updated this piece with the latest products (there are a ton) and found a few discount codes too.

Update 10/2/2023: This post has been updated since we originally published it. I evaluated additional top biological age tests for 2024, removed companies that are no longer offering tests, and updated the post to reflect the most recent pricing. The post has been cleaned up and links were made current.

According to TikTok, I’m either 46-years-old, 37-years-old, or 29-years-old. As a 34-year-old woman, that’s, ahem, less than ideal.

TikTok offers a filter that guesses how old the user is based on their uploaded face. Pulling my long hair up into a ponytail ages me by over a decade, and standing in natural lighting makes me appear younger than I actually am.
