Imagine if you were able to reverse aging and bring your body back to its original health and vigor.
Researchers have already discovered a group of drugs called senolytics which perform this miraculous transformation in mice and are testing them in humans as we speak.
UCLA scientists working with middle-aged fruit flies say they were able to improve the insects’ health while markedly slowing down their aging process. The team thinks its technique could eventually help delay the onset of Parkinson’s disease, Alzheimer’s disease, cancer, stroke, cardiovascular disease, and other age-related diseases in humans.
The researchers zeroed in on mitochondria, which often become damaged with age. When cells can’t eliminate the damaged mitochondria, they can become toxic and contribute to a wide range of age-related diseases, said David Walker, Ph.D., a UCLA professor of integrative biology and physiology, and the study’s senior author.
Dr. Walker and his colleagues found that as fruit flies reach middle age—about one month into their two-month lifespan—their mitochondria change from their original small, round shape.
During the recent Longevity and Cryopreservation Summit in Madrid, LEAF board member Paul Spiegel discussed the social ramifications of increased lifespans thanks to emerging technologies. He spoke of the need for society to adapt to deal with longer lives. We invite you to watch the talk he gave and also to read an interview providing deeper insight on the necessary changes in the pension system.
But first, a few words about Paul. Paul graduated cum laude from the University of California, Berkeley in 1979 and from Boalt Hall School of Law in 1983. He has attended Harvard Law School, the University of Paris, Sorbonne, and International Christian University in Tokyo.
Trained in international business law, he worked on Wall Street, on Montgomery Street, and in Tokyo before entering private practice in IP, business, and entertainment law in San Francisco.
The secret to a long life? A protein that acts as a cellular ‘time machine’ is found to extend the lifespan of fruit flies by 20%.
Biologists have turned back the clock on ageing in the cells of fruit flies, by increasing levels of a protein called Drp1.
This cellular time machine was found to lengthen the life-span of the insects by between 10 and 20 per cent.
Experts hope to develop drugs to mimic this effect in humans with age-related diseases including Alzheimer’s, extending people’s life expectancy and giving them more healthy years towards the end of their lives.
Oxford scientists are collaborating with artificial Intelligence company Insilico Medicine to prevent unnecessary animal sacrifice and derive more data from experiments in age related research.
The MouseAge.org initiative is being managed by UK charity; Biogerontology Research Foundation and will also include researchers from Harvard and Youth Laboratories in the development of tools for cross-species analysis and novel biomarkers of ageing and various diseases in mice.
Insilico Medicine which provides advanced machine learning services to skin care companies, is using the field of ‘omics’ to introduce a broad range of deep-learned biomarkers of ageing and age-related diseases.
By treating one of the root causes of aging – senescent cells – a new class of drugs, known as senolytics, has the potential to treat a wide range of age-related diseases rather than the traditional approach of dealing with them one at a time. We all age, but the research suggests that we may not have to suffer from age-related ill health.
So what are senescent cells?
As we age, increasing amounts of our cells enter into a state known as senescence. Normally, these cells destroy themselves by a self-destruct process known as apoptosis and are disposed of by the immune system. Unfortunately, as we age, increasing numbers of these cells evade apoptosis and linger in the body.
Unable to accept his own end, he decides to freeze his body. Sixty years later, in the year 2084, he becomes the first cryogenically frozen man to be revived in history. Marc discovers a startling future, but the biggest surprise is that his past has accompanied him in unexpected ways.
In case you’ve missed the news, Lifespan.io has another crowdfunding campaign running right now!
Before I’m too late for the party, I’d like to let you know that Lifespan.io’s crowdfunding campaign AgeMeter for the development of a diagnostic system to measure functional human age has been extended by two weeks. Presently, 70% of the necessary funds have been collected, i.e. a little over 20.000 dollars out of 30.000. It would be great if yet this other campaign made it to its goal, so if you haven’t made your donation yet, please do—remember, there’s no such thing as a donation which is too small: Broadly speaking, as long as the amount you donate is a positive real number, it is much appreciated! The AgeMeter campaign will end on September 16, 2017.
Contextually, another Lifespan.io crowdfunding campaign has been launched: MouseAge, an AI project aimed at assessing ageing biomarkers in mice visually, using image recognition techniques. If successful, this approach could help speed up rejuvenation research and reduce animal suffering. I’ll let the researchers speak:
A new study published by scientists at the Salk Institute recently shows how that changes in the nucleolus of progeria cells and normally aged cells share some characteristics that may allow them to be used as a biomarker for biological age[1].
What is Progeria?
Hutchinson-Gilford progeria is a rare genetic disease that causes people to suffer from aging-like symptoms on an accelerated timescale compared to regular aging. Whilst it shares similarities with regular aging it is not accelerated aging per se, but the outcome is much the same.
Kurzweil is one of the world’s leading minds on artificial intelligence, technology and futurism. He is the author of five national best-selling books, including “The Singularity is Near” and “How to Create a Mind.”
Raymond “Ray” Kurzweil is an American author, computer scientist, inventor and futurist. Aside from futurology, he is involved in fields such as optical character recognition (OCR), text-to-speech synthesis, speech recognition technology, and electronic keyboard instruments. He has written books on health, artificial intelligence (AI), transhumanism, the technological singularity, and futurism. Kurzweil is a public advocate for the futurist and transhumanist movements, and gives public talks to share his optimistic outlook on life extension technologies and the future of nanotechnology, robotics, and biotechnology.
Kurzweil admits that he cared little for his health until age 35, when he was found to suffer from a glucose intolerance, an early form of type II diabetes (a major risk factor for heart disease). Kurzweil then found a doctor (Terry Grossman, M.D.) who shares his non-conventional beliefs to develop an extreme regimen involving hundreds of pills, chemical intravenous treatments, red wine, and various other methods to attempt to live longer. Kurzweil was ingesting “250 supplements, eight to 10 glasses of alkaline water and 10 cups of green tea” every day and drinking several glasses of red wine a week in an effort to “reprogram” his biochemistry. Lately, he has cut down the number of supplement pills to 90.
