Ageing is not an inevitable fact of life – many animals have already found ways to delay death. Their clues might help us all enjoy longer and healthier lives.
Autophagy biology has emerged as a ray of hope in addressing age-related diseases such as neurodegenerative disorders. Substantial effort in academia has been directed at advancing our understanding of the field and paving the way for ground-breaking therapies. But with genuine challenges in harnessing the power of autophagy and in developing effective therapies in this disease area, how close are we to really finding the first autophagy boosting drugs…?
The devastating impact of neurodegenerative diseases such as Parkinson’s, Alzheimer’s and amyotrophic lateral sclerosis (ALS), the most common form of Motor Neurone Disease (MND), cannot be overstated. According to the WHO, neurological diseases affect over a billion people globally and are the leading cause of disability and the second leading cause of death worldwide [1, 2]. Incidence is increasing too, predominantly driven by population growth and aging. And, with no prospect of a cure, people who develop these conditions face a bleak future.
Justifiably, this disease area has been the subject of intensive research for many years and there have been some breakthroughs along the way, possibly offering hope for the development of new therapies. However, translating scientific breakthroughs into viable drugs for patients has been enormously challenging.
In the 1990 fantasy drama — Truly, Madly, Deeply, lead character Nina, (Juliet Stevenson), is grieving the recent death of her boyfriend Jamie (Alan Rickman). Sensing her profound sadness, Jamie returns as a ghost to help her process her loss. If you’ve seen the film, you’ll know that his reappearance forces her to question her memory of him and, in turn, accept that maybe he wasn’t as perfect as she’d remembered. Here in 2023, a new wave of AI-based “grief tech” offers us all the chance to spend time with loved ones after their death — in varying forms. But unlike Jamie (who benevolently misleads Nina), we’re being asked to let artificial intelligence serve up a version of those we survive. What could possibly go wrong?
While generative tools like ChatGPT and Midjourney are dominating the AI conversation, we’re broadly ignoring the larger ethical questions around topics like grief and mourning. The Pope in a puffa is cool, after all, but thinking about your loved ones after death? Not so much. If you believe generative AI avatars for the dead are still a way out, you’d be wrong. At least one company is offering digital immortality already — and it’s as costly as it is eerie.

Some best practices for longevity can be a real bummer. Everyone knows that regular exercise is good for them, but not everyone enjoys it. Eating a few cups of veggies with every meal may not be as fun as a side of fries.
But every so often, the things that are good for us feel good too. Case in point: the humble massage.
A massage for most people is a spa-day splurge, but it’s also an ancient medicinal practice. A thorough rub-down is a great way to celebrate the end of a stressful semester, but there’s more to it than much-deserved relaxation. At its best, a good massage improves bodily motion and function. While science doesn’t say that each massage adds years to your life (not yet, anyway), the benefits of regular massages (for those lucky enough to get them) can add up over time.
In a recent perspective piece published in the Nature Medicine Journal, researchers discussed the current achievements, challenges, and potential opportunities in using digital technologies, such as remote medicine and wearables in geriatric medicine and care.

Discussion: Much of the association between happiness and increased life expectancy could be explained by socio-demographic, lifestyle, health and functioning factors, and especially psychological health and functioning factors.
Keywords: Happiness; Longevity; Mortality; Positive affect; Well-being.

A VERY interesting 6 minutes. People tests? One pill? Next Gen? Hurry, I’m 52! There is an ongoing idea that it will take several kinds of treatments, but many years ago I recall Cynthia Kenyan talking about how some research shows it might come down to a pill.
David Sinclair shares the latest incredible research they are doing.

In a groundbreaking study, researchers have unlocked a new frontier in the fight against aging and age-related diseases. The study, conducted by a team of scientists at Harvard Medical School, has published the first chemical approach to reprogram cells to a younger state. Previously, this was only achievable using a powerful gene therapy.
The team’s findings build upon the discovery that the expression of specific genes, called Yamanaka factors, could convert adult cells into induced pluripotent stem cells (iPSCs). This Nobel Prize-winning discovery raised the question of whether it might be possible to reverse cellular aging without causing cells to become too young and turn cancerous.
