Getting older means losing things. Some are fine, like any f**ks you have left to give or your tolerance for cheap tequila. Others, like the ability to follow a conversation in a loud room, hit harder.
But scientists now think there’s a way to fight back. And it might start at a piano bench.
Researchers publishing in PLOS Biology found that older adults who have played music for decades have brains that function more like those of someone half their age, at least when it comes to understanding speech in loud environments. In brain scans, they showed cleaner, more focused activity while listening to spoken syllables buried in background noise. Their brains weren’t scrambling. They already knew what to do.
Vascular aging and genetic risk jointly shape coronary artery disease susceptibility across races and sexes.
BackgroundEstimated pulse wave velocity (ePWV), a noninvasive marker of arterial stiffness, reflects vascular aging and has been associated with increased coronary artery disease (CAD) risk. However, the interplay between ePWV and genetic factors, including polygenic risk score (PRS) and apolipoprotein E genotypes, in determining CAD susceptibility remains unclear.
Think of cells as the biological answer to battery-powered electronics. Mitochondria are the batteries that supply them with enough energy to keep going. Unfortunately, just like the two standard AAs in your remote control, they eventually run out of power and die—but (much like actual batteries) they can also be recharged and replaced.
Breakdown of mitochondria causes cells to glitch. Wear and tear can happen with age, usually from years of exposure to free radicals that cause oxidative stress and inflammation, but can also be caused by injury from degenerative diseases or mitochondrial toxicity from certain drugs and other harmful substances. When there is damage to the cell, mitochondria begin to lose their capacity to generate energy. Losing mitochondria is detrimental to cell function. This is why biomedical engineer Akhilesh Gaharwar and his research team at Texas A&M University have come up with a way to regenerate them.
Lipofuscin, a marker of aging, is the accumulation of autofluorescent granules within microglia and postmitotic cells such as neurons. Lipofuscin has traditionally been regarded as an inert byproduct of cellular degradation. However, recent findings suggest that lipofuscin may play a role in modulating age-related neurodegenerative processes, and several questions remain unanswered. For instance, why do lipofuscin granules accumulate preferentially in aged neurons and microglia? What happens to these pigments upon neuronal demise? Particularly in neurodegenerative diseases like Alzheimer’s disease (AD), why does amyloid β (Aβ) deposition usually begin in late adulthood or during aging? Why do lipofuscin and amyloid plaques appear preferentially in grey matter and rarely in white matter? In this review, we argue that lipofuscin should be revisited not as a simple biomarker of aging, but as a potential modulator of neurodegenerative diseases. We synthesize emerging evidence linking lipofuscin to lysosomal dysfunction, oxidative stress, lipid peroxidation and disease onset—mechanisms critically implicated in neurodegeneration. We also explore the potential interactions of lipofuscin with Aβ and their spatial location, and summarize evidence showing that lipofuscin may influence disease progression via feedback loops affecting cellular clearance and inflammation. Finally, we propose future research directions toward better understanding of the mechanisms of lipofuscin accumulation and improved lysosomal waste clearance in aging.

The secret to a healthier and “younger” heart lies in the vagus nerve. A recent study coordinated by the Sant’Anna School of Advanced Studies in Pisa and published in Science Translational Medicine has shown that preserving bilateral cardiac vagal innervation is an anti-aging factor. In particular, the right cardiac vagus nerve emerges as a true guardian of cardiomyocyte health, helping to preserve the longevity of the heart independently of heart rate.
The study is characterized by a strongly multidisciplinary approach, integrating experimental medicine and bioengineering applied to cardiovascular research. Specifically, the research was led by the Translational Critical Care Unit (TrancriLab) of the Interdisciplinary Research Center Health Science, under the responsibility of Professor Vincenzo Lionetti, and by the laboratory of the Biorobotics Institute led by Professor Silvestro Micera, which contributed to the development of the bioabsorbable nerve conduit used to facilitate vagal regeneration.
The study involved a broad network of Italian and international institutions of excellence, including the Scuola Normale Superiore, the University of Pisa, the Fondazione Toscana G. Monasterio, the Institute of Clinical Physiology of the CNR, the University of Udine, GVM Care & Research, Al-Farabi Kazakh National University, the Leibniz Institute on Ageing in Jena and the École Polytechnique Fédérale de Lausanne.
