DNA damage is common to our cells, but when we’re young our bodies can fix it pretty easily. Unfortunately we lose that ability over time, leading to many of the symptoms of aging that we know all too well. A new study from MIT has found that reactivating a certain enzyme improves repair of DNA damage in neurons, which helps Alzheimer’s patients and others with cognitive decline.

Previous studies by the team have shown that an enzyme called HDAC1 seems to be involved in DNA repair in neurons. For the new study, the researchers examined what happens when HDAC1 doesn’t do its job.

The team engineered mice to be deficient in HDAC1, and monitored their health compared to normal mice. Things looked good during the animals’ youth – there were no differences in DNA damage or behavior between the two groups. But as they aged, the decline became clear.

If you’re interested in superlongevity and superintelligence, then I have a book to recommend., by Sonia Contera, is a book about the intersection of biotech and nanotech. Interesting and well written for the layman, the book covers some of the latest developments in nanotechnology as it applies to biological matters. Although there are many topics, I was primarily interested in the DNA nanobots, DNA origami, and the protein nanotechnology sections. My interest is piqued in these arenas due to my expectation that DNA nanobots and protein nanobots, as well as complex self-assembled custom nanostructures, are going to be key to some of the longevity technologies and some of the possible substrates for mind uploading that are key to superlongevity and superintelligence. There are also sections in the book on 3D bioprinted organs — progress and possibilities, as well as difficulties.

There is even a section that clearly was written specifically to address a discussion that has engaged my friends, Dinorah Delfin and Dan Faggella. The title is:

FUTURE DEVICES: QUANTUM PHYSICS MEETS BIOLOGY MEETS NANOTECHNOLOGY

Now, some might be tempted to consider that particular combination to be “woo woo”, however, please keep in mind the author’s credentials. Sonia Contera is a professor of biological physics in the Department of Physics at the University of Oxford.

If you’re interested in superlongevity and cognitive enhancement, I have a YouTube video to recommend. Our good friend, Ira Pastor, on his excellent podcast ideaXme, discusses with Dr. Rudolph Tanzi the topic of inflammaging, specifically brain inflammation, plaque, tau tangles, brain health, and Alzheimer’s disease. Then they discuss some emergent therapies to prevent Alzheimer’s by protecting the neurons.

The discussion is concise and complete, but also very easy to follow.

Biological age and biomarkers improved to that of rats half their age. Blog post from the Live Forever Club.

Humans are living longer than ever before. But alongside these increases in life expectancy are an increase in the occurrence of age-related diseases such as cancer and dementia.

But understanding the biology of ageing, and knowing the genes and proteins involved in these processes, will help us increase our “healthspan”—the period that people can live in a healthy and productive state, without age-related diseases.

In a recent study, our team identified a novel anti-ageing protein, called Gaf1. We found that Gaf1 controls protein metabolism, a process that has been implicated in ageing and disease. We also found that without Gaf1, cells have a shorter lifespan.

A study published in Current Biology reports on one of the first comprehensive characterizations of poorly formed memories, and may offer a framework to explore different therapeutic approaches to fear, memory and anxiety disorders. It may also have implications for accuracy of some witness testimony.

Senior author Professor Bryce Vissel, from the UTS Centre for Neuroscience & Regenerative Medicine, said his team used novel behavioral, molecular and computational techniques to investigate memories that have not been well-formed, and how the brain deals with them. “For memories to be useful, they have to have been well-formed during an event—that is, they have to accurately reflect what actually happened.

”However, in the real world many memories are likely to be inaccurate—especially in situations where the experience was brief, sudden or highly emotional, as can often occur during trauma. Inaccurate memories can also occur when the memory is poorly encoded, potentially as a result of subtle differences in how each person processes memory or because of disease like Alzheimer’s or dementia.”

A team at Harvard has identified molecules that restore protective caps on the tips of our chromosomes that regulate cells ageing.
