How Zinc Protects Injured Arteries From Accelerated Aging

Researchers publishing in Aging Cell have discovered that the nuclei of the cells that line injured arteries quickly become misshapen and that this leads to accelerated cellular senescence. Delivering zinc to these cells partially alleviates this dysmorphism.

Two seemingly unrelated concepts

This paper begins with a discussion of two different concepts that, on the surface, appear to be unrelated. First, the researchers discuss vascular damage, particularly in the context of surgeries; even minimally invasive procedures that involve cutting, scraping, or burning arteries must cause some level of damage. This includes such procedures as catheter implantation as a treatment for heart disease [1] and the resection of cancerous tumors [2].

Exercise Triggers Memory-Related ‘Brain Ripples’, Study Finds

Exercise works wonders throughout the human body, including the brain.

Research suggests an array of neurological benefits, such as reducing the brain’s biological age, enhancing learning and memory, and protecting against dementia.

Now, a new study offers one of the clearest glimpses yet into a suspected mechanism: after a single 20-minute session of light-to-moderate cycling, people showed changes in memory-linked brain activity.

Dick Van Dyke Credits His Longevity to One Habit, And Science Supports It

Dick Van Dyke, the legendary American actor and comedian who starred in classics such as Mary Poppins and Chitty Chitty Bang Bang, turned 100 on December 13. The beloved actor credits his remarkable longevity to his positive outlook and never getting angry.

While longevity of course comes down to many factors – including genetics and lifestyle – there is some truth to Van Dyke’s claims.

Numerous studies have shown that keeping stress levels low and maintaining a positive, optimistic outlook are correlated with longevity.

Lifelong behavioral screen reveals an architecture of vertebrate aging

By tracking nearly every movement of a tiny fish’s life from adolescence to death, a new Science study reveals a hidden behavioral blueprint of aging—one that can predict a fish’s age or how long an individual will live.

Mapping behavior of individual vertebrate animals across lifespan could provide an unprecedented view into the lifelong process of aging. We created a platform for high-resolution continuous behavioral tracking of the African killifish across natural lifespan from adolescence to death. We found that animals follow distinct individual aging trajectories. The behaviors of long-lived animals differed markedly from those of short-lived animals, even relatively early in life, and were linked to organ-specific transcriptomic shifts. Machine-learning models accurately inferred age and even forecasted an individual’s future lifespan, given only behavior at a young age. Finally, we found that animals progressed through adulthood in a sequence of stable and stereotyped behavioral stages with abrupt transitions, revealing precise structure for an architecture of aging.

Recycling senescent cell lipids for targeted senotherapy

Ji, He, Cai, and colleagues report an engineered senescence therapy that exploits lipid metabolic features of senescent cells, repurposing excess lipids as functional resources to improve joint function, and thus alleviating osteoarthritis without eliminating the cells.

Revisiting the proto-transhumanists: Diderot and Condorcet

Think transhumanism is a relatively new social and intellectual phenomenon? Guess again.

Many of the ideas characteristic of the movement have already been bantered about for literally hundreds of years—whether it be such things as radical life extension or the construction of machine minds. The Enlightenment period in particular was a fruitful time for these ideas to take flight, mostly on account of the new sciences, the rise of rationalism and secular humanism, and the waning influence of religion. Two thinkers that best exemplified Enlightenment-era proto-transhumanism were Denis Diderot and Marquis de Condorcet, and their early contributions are worth revisiting.

Cell-type specific TDP-43 pathology in the motor cortex

The hallmarks of cancer comprise six biological capabilities acquired during the multistep development of human tumors. The hallmarks constitute an organizing principle for rationalizing the complexities of neoplastic disease. They include sustaining proliferative signaling, evading growth suppressors, resisting cell death, enabling replicative immortality, inducing angiogenesis, and activating invasion and metastasis. Underlying these hallmarks are genome instability, which generates the genetic diversity that expedites their acquisition, and inflammation, which fosters multiple hallmark functions.
