A comprehensive review in the journal Cell outlines a unified framework for classifying and validating aging biomarkers, aiming to streamline their integration into clinical research and practice. The study categorizes biomarkers into types like molecular, functional, and clinical, and sets criteria for their feasibility, validity, and applicability, all with the goal of better understanding and intervening in the aging process.

This week in neuroscience, we’ve seen groundbreaking advancements ranging from a diet that can potentially extend lifespan without calorie restriction, to a new drug that could revolutionize obesity treatment.

The Death of Death is an international bestseller by José Cordeiro and David Wood that claims that “death will be optional by 2045” – or even earlier, if more public and private funds are invested in rejuvenation technologies.

Longevity. Technology: Already available in more than 10 languages, the book provides insight into recent exponential advances in AI, tissue regeneration, stem cell treatment, organ printing, cryopreservation and genetic therapies that, say the authors, offer a realistic chance to solve the problem of the aging of the human body for the first time in human history. In fact, the book’s subtitle is The Scientific Possibility of Physical Immortality and its Moral Defense.

Given that until relatively recently, just mentioning the concept of ‘biological immortality’ was enough to raise eyebrows and with most of the opinion that it should be filed away under ‘science fiction’ or ‘charlatanism’. However, longevity science is advancing at an incredible pace and today there are people who no longer wonder if immortality is possible, but when it will be a reality. We sat down with José Luis Corderio PhD to find out more.

Global worming?

Scientists recently revived microscopic creatures frozen for 46,000 years in the Siberian permafrost.

The ancient nematodes, better known as roundworms, are able to shut their bodies down in unsuitable environments — a process called anabiosis.

After a certain age, approximately 40% of people experience some degree of hearing loss. While age-related hearing loss is most prevalent in adults over the age of 65, it can start occurring far earlier than that, when people are in their 40s or 50s.

Despite their widespread use, existing diagnostic techniques might be unable to detect earlier signs of hearing loss, such as the loss of the ability to hear speech in crowded or noisy environments. Some researchers have thus been trying to devise viable techniques to detect subtler forms of hearing loss, so that they can be addressed early, before they are irreparable.

To this end, two neuroscientists at the Rotman Research Institute in Canada have recently been exploring the relationship between effortful listening and eye movements. Their most recent paper, published in The Journal of Neuroscience, suggests eye movements tend to decrease while young adults are placing greater effort in trying to hear speech.

Scientists from the Babraham Institute suggest an alternative connection between diet and aging, based on studies in yeast. Dr. Jon Houseley and his team have published their experiments, demonstrating that healthy aging is achievable through dietary change without restriction by potentially optimizing diet and that ill health is not an inevitable part of the aging process.

Scientists have long known that caloric restriction – intentionally consuming far fewer calories than normal without becoming malnourished – improves health in later life and may even extend life. However, studies in mice show that caloric restriction really needs to be maintained throughout life to achieve this impact, and the health benefits disappear when a normal diet is resumed. Dr. Houseley’s new research conducted in yeast suggests an alternative to calorie restriction can lead to improved health throughout the lifecycle.

A collaboration between researchers at the University of Sheffield and Budapest Zoo sees an aging gorilla walk again with ease. Will this treatment be fruitful for humans?

Scientists at the university of sheffield.

Liesel, the elderly matriarch of the Budapest Zoo, had been struggling to walk on her left leg, signaling a possible battle with arthritis. This marked the initiation of a unique collaboration between veterinary expertise and cutting-edge science to alleviate the suffering of the aging primate.

The research paper reviews the potential benefits of marine plasmalogens, a type of glycerophospholipid, in combating age-related diseases like Alzheimer’s and Parkinson’s. These compounds, abundant in marine resources, could improve lipid metabolism and reduce oxidative stress, offering a new avenue for improving the quality of life in aging populations.
